Description

[0001] Endoscope, base module and handling module for an endoscope, sterile single-use product, system and method for providing an endoscope

[0002] The present invention relates to an endoscope, a base module for an endoscope, a handling module for an endoscope, a sterile single-use product, a system and a method for providing an endoscope.

[0003] An endoscope is often used to perform a diagnostic and / or therapeutic procedure on a hard-to-reach part of a patient's body. Hard-to-reach parts of the body are particularly hollow spaces such as a body cavity and / or a hollow organ. The endoscope is designed in such a way that it can be partially guided into the patient's cavity to perform the diagnostic and / or therapeutic procedure. To visualize anatomical structures or to better monitor the diagnostic and / or therapeutic procedure, the endoscope is usually configured to shine light into the patient's cavity.

[0004] Endoscopes consist of an elongated shaft that is partially inserted into the patient's cavity. To examine an anatomical structure, the distal end of the shaft is aligned so that it points directly toward the anatomical structure. This allows the anatomical structure to be specifically illuminated. The light reflected from the anatomical structure can then be captured by the distal end of the shaft for imaging. After imaging, the anatomical structure can be displayed to a user.

[0005] For handling, endoscopes comprise a handle and / or a handling section that has an ergonomic shape for better handling. The handle is often milled from a solid metal material, which is sometimes a complex and / or cost-intensive manufacturing step. The handle manufactured in this way is permanently connected to the other parts of the endoscope. In addition, electronic components, control elements and / or the like can be provided in the handle. However, for some applications of the endoscope it may turn out that a different shape of the handle would be advantageous. The user is then faced with the choice of continuing to use the endoscope with the less advantageously shaped handle or using a different endoscope that has a advantageously shaped handle.

[0006] Furthermore, when using endoscopes for medical purposes, it is essential to ensure that they are sterile and can be sterilized as easily and reliably as possible. Consequently, the handle and the entire endoscope must meet specific requirements regarding tightness, particularly fluid and / or gas tightness. The endoscope, and especially the handle, must enclose the electronics contained within it in such a way that the entire endoscope, including the permanently fixed handle, can be sterilized as easily and reliably as possible. This may include autoclaving, which imposes high requirements for temperature resistance and gas tightness.

[0007] Furthermore, it may be provided that the endoscope is partially covered with a sterile disposable sheath, a so-called "drape," to at least largely protect critical sections of the endoscope, especially the handle, from contamination during a procedure. The process of covering the endoscope with the sterile disposable sheath can be time-consuming and / or labor-intensive. Furthermore, the sterile disposable sheath is usually intended for single use.

[0008] Another aspect related to endoscopes is the multitude of different types of endoscopes, each designed for a specific application. These endoscopes comprise electronic components adapted for the respective application, which may be integrated with a handle. This can result in a highly fragmented development and / or manufacturing process in which only minimal synergies between different types of endoscopes are exploited. Consequently, it can be comparatively costly for endoscope manufacturers to offer a broad product range.

[0009] Yet another aspect can relate to the development of heat during operation of endoscopes. In particular, waste heat generated by electronic devices, especially lighting elements such as LEDs, can heat up the handle, which is made of metal and permanently connected to the rest of the endoscope. As a result, the handle can heat up to such an extent that the user can hardly grip it and / or the power of the electronic devices has to be reduced. In general, the power of the electronic devices can be restricted or limited by the heating of the handle. This can sometimes result in limitations on the maximum light intensity. This is not caused by the built-in or generally installable lighting elements, but by the undesirable development of waste heat, which can affect the user's comfort or the handling of the endoscope.

[0010] Furthermore, one aspect relates to a cable that connects the endoscope to a power unit. This cable may have a preferred rotational position relative to the endoscope and / or define a preferred rotational position of the endoscope, which may result in disadvantages when using the endoscope. Connecting the endoscope may therefore require a high degree of attention to properly position the components involved and establish the connection correctly. Furthermore, the cable may be designed such that cable replacement can only be performed by trained specialists.

[0011] Based on the prior art, it is an object of the present invention to improve the flexibility, efficiency and / or cost-effectiveness of an endoscope.

[0012] The object can be achieved according to the invention by an endoscope, a base module for an endoscope, a handling module for an endoscope, a sterile single-use product, a system and a method for providing an endoscope, as described herein and defined in the claims.

[0013] According to the invention, an endoscope can be provided. The endoscope can comprise a base module. The base module comprises a housing and control electronics, wherein the housing encloses the control electronics. Furthermore, the endoscope can comprise a handling module that is configured to make the base module manageable and that comprises a base body that defines a receiving space for the base module. The base module can be introduced into the receiving space of the handling module by a user to establish a manageable state. Furthermore, the handling module and the base module can jointly form a fixing mechanism by means of which the housing can be releasably fixed to the handling module. According to the invention, a base module for an endoscope can also be provided.

[0014] According to the invention, a handling module for an endoscope can also be provided.

[0015] According to the invention, a system can also be provided. The system can comprise a base module and at least two different handling modules, wherein the two handling modules implement different functionalities in a manageable state of the base module. In other words, a first handling module can implement a first functionality in a first manageable state of the base module, in which the base module is inserted into the first handling module, and a second handling module can implement a second functionality, which is different from the first functionality, in a second manageable state of the base module, in which the base module is inserted into the second handling module.

[0016] According to the invention, a method for providing an endoscope to a user can also be provided. The method comprises providing the base module, providing the handling module, and inserting the base module into the handling module by the user.

[0017] Advantageously, an endoscope can be provided that is characterized by high flexibility, high efficiency, and / or low operating costs. The endoscope can be configured by the user for a specific application, thus improving the quality of use of the endoscope. Furthermore, development and / or manufacturing costs can be saved. Furthermore, it is possible to react more quickly and / or more precisely to events during use of the endoscope; for example, should it become apparent during use that a different handling module is advantageous. The user can configure the endoscope, and in particular the handling, in an optimized manner based on their own needs and / or requirements. The design of the endoscope can be simplified by providing modules that each have their own function.For example, the handling module can be compatible with various base modules, thus enabling standardized handling modules to be provided. Furthermore, the overall material usage and / or energy expenditure for use over a longer period of time can be reduced. The inventors have recognized that conventional draping is a comparatively complicated process that regularly requires at least two people. This presents a risk of contamination. The invention makes it possible to provide all components in a sterile manner. These can be assembled by a single person. This increases patient safety, particularly with regard to hygiene. Furthermore, the inventors have determined that the cost of a drape is the same as that of a single-use handling module, particularly if it is designed as an injection-molded part, for example.In both cases, single-use products are disposed of, so there are no significant differences in terms of waste generated. Handling modules according to the invention may even be advantageous in this regard because they are easier to recycle.

[0018] The features described herein are generally usable for an endoscope and / or an endoscope device. Thus, in some aspects, the disclosure generally relates to an endoscope device. The endoscope device may comprise a base module. The base module comprises a housing and control electronics, wherein the housing encloses the control electronics. The endoscope device may comprise a handling module. The base module may be insertable into the receiving space of the handling module to create a manageable state. This may occur during manufacture of the endoscope. This may alternatively or additionally be performed by a user. The handling module and the base module may jointly form a fixing mechanism by means of which the housing may be fixed to the handling module. The fixing may be releasable. It is understood that the aspects described below may be combined with the general aspects mentioned.

[0019] The disclosure further relates to an endoscope having such an endoscope device. Furthermore, the disclosure relates to a method for producing such an endoscope device and / or such an endoscope.

[0020] The endoscope can be a flexible and / or a rigid endoscope. For example, the endoscope can comprise a section that is movable and / or controllable.

A main extension axis can extend along the main extension direction. A "main extension direction" of a component is understood to mean, in particular, a direction that runs parallel to a longest edge of the smallest imaginary cuboid that just completely encloses the component.

[0023] The user can be an end user and / or a user. In particular, the user is not involved in the manufacture of the base module and / or the handling module. Furthermore, the user is not involved in bringing the endoscope into a sale-ready state and / or in production and / or manufacturing prior to distribution of the endoscope. Rather, the user can use the endoscope in a state in which it has already been purchased. The user can be a doctor, a medical assistant, clinical staff and / or medical staff. The manageable state is created in particular in a patient-related context. The manageable state is created, for example, immediately before use of the endoscope, for example no more than 60 minutes, no more than 30 minutes, no more than 10 minutes or even no more than 5 minutes before use.The creation of the handleable state may serve to make the endoscope ready for operation. In particular, the creation of the handleable state does not take place within the scope of manufacturing and / or production and / or in a factory and / or plant.

[0024] The control electronics comprise electronic components configured to enable imaging by means of the endoscope. For example, the control electronics may comprise a computing unit such as a microprocessor, a communication and / or network element, a memory element, a voltage converter, and / or a motor controller. The control electronics may be configured to supply the elements configured to generate image data, for example, the image sensor and / or the lighting element, with electrical energy and / or to control a function. For example, the generation of image data may be initiated and / or brightness may be adjustable. Furthermore, the control electronics may be configured to digitize image data, particularly when the image sensor is a CCD sensor, a CMOS sensor, a silicon image sensor, a SWIR image sensor, or another digital sensor.The control electronics can, in principle, be configured to operate many different elements. These elements can be provided as needed, for example, depending on the type of endoscope and / or the endoscope's application, and can be coupled and / or compatible with the control electronics.

[0025] In addition, the control electronics can be configured to transmit image data to a supply unit and / or a display unit. The supply unit can be configured to process the image data. The display unit can be configured to display the image data, particularly during operation of the endoscope. The housing can be configured to absorb waste heat from the control electronics and / or the components of the base module and / or to dissipate it via an outer surface of the housing, particularly to an environment of the housing. The housing can also be configured to enclose the control electronics in a fluid-tight manner.

[0026] The handling module can generally provide an interface for mechanical manipulation of the endoscope. Making it manageable can mean, for example, that the handling module can be grasped by a user and / or that the endoscope can be moved spatially. Furthermore, the endoscope can be attachable to a robot, in particular a medical robot, by means of the handling module and / or can be grasped and / or held by the robot. In this context, the user can establish the manageable state by initiating a particularly automatic establishment of the manageable state by a robot, in particular by operating an interface to the robot. The robot can be configured to perform an action, in particular a diagnostic action and / or an intervention. Furthermore, the endoscope can be attachable to a holding arm by means of the handling module.The holding arm can be configured to hold the endoscope, in particular to assist the user in performing the action. Furthermore, the handling module can have an ergonomic shape with regard to use by the user. This can mean, in particular, that the handling module has a preferred orientation with respect to a user's grip. The handling module can be free of electrical and / or electronic components. The handling module can be free of an electrical power supply and / or a power supply and / or an electrical energy storage device.

[0027] The handling module can be compatible with multiple base modules. For example, the system can comprise different base modules, each implementing a different functionality. The different base modules, in particular the housings of the base modules, can be inserted into the receiving space of the handling module and / or the base modules can be releasably fixable to the handling module. In particular, the base body can form the ergonomic shape on a lateral circumferential surface. The receiving space can have a size and / or shape that ensures that the base module, in particular the housing, can be inserted into the receiving space with a significant degree of precision. In some embodiments, the base module, in particular the housing, is at least partially spaced from inner surfaces of the receiving space and / or from inner walls of the base body when the handling module is inserted.Insertable can in particular mean insertable, insertable, pluggable, pushable and / or pressable.

[0028] The fixing mechanism can in particular be designed to at least substantially restrict axial mobility of the base module relative to the handling module. Furthermore, lateral and / or rotational relative movement can be restrictable. The fixing mechanism can comprise at least one movable part. The movable part can be provided on the handling module. Alternatively or additionally, the movable part can be provided on the base module. Releasably fixable can in particular mean that the handling module can be quickly, easily and / or reversibly fixed to the base module. In particular, the handling module can be repeatedly fixed to and detached from the base module without damage. In particular, the base module can be used repeatedly. Damage-free can in particular refer to the base module.In some embodiments, it can be provided that the handling module is designed to be releasably fixable in such a way that it is destroyed and / or damaged if it is released. For example, the handling module can be connectable and / or detachable within 30 seconds, in particular within 20 seconds and preferably within 10 seconds. Preferably, simple can mean that the handling module can be connectable and / or detachable by just a single user, preferably without tools. The fixing mechanism can be passive or active. Passive can mean that the base module can be activated by inserting the base module into the receiving space. Active can mean that the fixing mechanism can be operated and / or activated by the user, in particular when the base module is inserted into the receiving space.In some embodiments, the fixation mechanism can be provided on a portion of the base module and / or the handling module that is proximal to the user. Furthermore, the fixation mechanism can be provided on a proximal end surface of the base module and / or the handling module. Alternatively or additionally, the fixation mechanism can be provided on a lateral side surface of the base module and / or the handling module.

[0029] In particular, the handling module can be intended for single use. This can mean that the user inserts the base module, in particular the sterilized base module, into the receiving space of the handling module shortly before performing an action, for example, a few minutes. After the action, in particular a therapeutic and / or diagnostic action, has been performed, the user can detach the handling module from the base module.

[0030] For example, the user can integrate the base module into another handling module. The other handling module can have other application-specific features that are advantageous for a particular application.

[0031] According to the invention, a sterile single-use product can also be provided. The sterile single-use product can comprise a handling module and sterile outer packaging, wherein the handling module is packaged in a sterile state in the outer packaging. Advantageously, the user can quickly make the endoscope ready for use. The endoscope can be provided in such a way, or the base module can be inserted in such a way, that the endoscope does not need to be sterilized before use. This can enable significant time savings, a high level of convenience, and / or a flexible and / or rapid response to events during use.

[0032] In addition, the handling module can be configured to make the base module manageable and operable for the user, and an operable state can be achieved by introducing the base module into the receiving space. In the operable state, the endoscope can be at least substantially fully usable by the user. Advantageously, the user can, for example, handle an application-specific base module using a handling module that is advantageous for them. In particular, the base module cannot be fully handled without the handling module. The usability of the endoscope can arise from the user connecting the base module to the handling module. The endoscope can be intended to be purchased and / or kept in stock and / or stored disassembled into the individual components base module and handling module, and to be made ready for operation only before use by assembling these individual components.Furthermore, the base module can be detachable and / or fixable to the handling module without tools. Operation can be simple. Tool-free can specifically mean that the user does not need any additional items to attach and / or detach the base module to / from the handling module.

[0033] Furthermore, the fixing mechanism can comprise a prestressed and / or prestressable prestressing element. For example, the fixing mechanism can comprise a spring, in particular a spiral spring, a torsion spring, a disc spring and / or an annular spring. The prestressing element can generate a prestressing force. A fixing force can be connected to the prestressing force. The prestressing element can be prestressed by inserting the base module. For example, the base module and / or the handling module can comprise a clamping element, for example a projection, a stop, a ramp, a wedge, an elevation and / or the like, along which the prestressing element can be guided. The clamping element can extend in particular in a direction in which the prestressing force acts partially and / or substantially. Furthermore, the prestressing force can be provided specifically for the base module.For example, in the context of a larger and / or heavier base module, a greater preload force and / or fixing force can be provided. In some embodiments, the preload force can act partially and / or at least substantially in a radial direction. The fixing mechanism can be characterized by ease of use. In particular, a single user can fix the base module and / or the base module can be fixable by a single user. High operational reliability and / or user-friendliness can be achieved.

[0034] In addition, the fixing mechanism can comprise a holding element configured to releasably fix the housing to the handling module by engaging behind it. The holding element can be provided on the handling module. Alternatively, the holding element can be provided on the base module, in particular the housing. The fixing mechanism can comprise further holding elements configured to releasably fix the housing to the handling module by engaging behind it. The holding elements can be provided on the handling module and / or the base element, in particular the housing. By engaging behind it, a high degree of fixing force can be achieved. This can significantly increase operational reliability. In addition, the detachability of the base module can be implemented in a structurally simple manner.Furthermore, the fixing mechanism can have at least one rotatable fixing element, wherein the rotatable fixing element can be moved by rotation between a fixing state and a release state. In particular, "rotatable" can mean rotatable about a rotation axis. For example, the rotation axis can be arranged coaxially with the main extension direction and / or with a longitudinal axis of the base module. In the release state, the base module can be inserted into the receiving space of the handling module by a user to establish the manageable state. In some embodiments, an axial force can be exerted on the base element and / or the handling module by the rotatable fixing element. The fixing mechanism can further comprise a pretensioning element. Such a fixing mechanism can be characterized by high reliability and low susceptibility to failure.The user can receive almost immediate feedback about a successful fixation. The fixation status can be easily visible to the user.

[0035] Furthermore, the receiving space can be opened and closed. Openable can mean that the receiving space can be made laterally accessible. For example, a lateral side of the receiving space can be removable. In particular, the receiving space can also be opened and / or closed by the user. Advantageously, operational reliability and user-friendliness can be increased. The receiving space can have an open and closed state. In the open state, the base module can be inserted into the receiving space and / or removed from the receiving space. In the closed state, the base module cannot be inserted into the receiving space and / or removed from the receiving space. Opening and / or closing the receiving space can comprise a mechanical movement of at least one component of the handling module, in particular by the user.

[0036] Furthermore, when the receiving space is open, the base module can be inserted into the receiving space, and when the receiving space is closed, the housing can be fixed to the handling module. In particular, the housing can be inserted into the receiving space. The housing can be inserted and / or fixed by a user. In this context, insertable can mean, in particular, insertable. In particular, the base module, in particular the housing, can be inserted into the receiving space from a lateral side and / or in a direction perpendicular to the main extension direction and / or longitudinal axis of the base module and / or the handling module and / or the receiving space. Advantageously, in the closed state, at least the housing is enclosed by the receiving space, or the receiving space at least substantially encloses the housing. In particular, the control electronics can be protected in this way.A malfunction can be prevented. Advantageously, operational reliability can be increased. Another advantage can be that the base module can be inserted into the receiving space in particular such that the user grips the base module in the area of ​​the housing. For example, the user can grip the base module at the housing and insert it, in particular, into the receiving space. This can be particularly advantageous if the base module is designed to be more stable and / or robust in the area of ​​the housing compared to other sections of the base module. For example, the base module can be inserted into the receiving space without having to grip an endoscope shaft. The risk of damage to the base module during insertion can be significantly reduced.

[0037] Furthermore, the base body can comprise at least two base body parts that are hingedly connected to one another and movable relative to one another for opening and closing the receiving space. In particular, the two base body parts can be pivotally movable relative to one another and / or define a pivot axis. For example, the pivot axis can be arranged parallel to the main extension direction and / or the longitudinal axis of the base module. This can make insertion particularly simple and / or safe. Furthermore, the endoscope can be particularly user-friendly.

[0038] Furthermore, the base body can comprise a handle. Advantageously, the handle can be formed integrally and / or in one piece with the base body. The handle can be designed in such a way that it provides the user with a high level of grip comfort. In particular, the handle can be irregularly and / or asymmetrically designed. Operating costs and / or manufacturing costs can be reduced.

[0039] Furthermore, in the manageable state, the handle can at least partially encompass the housing. This makes it possible to achieve a compact design. In addition, the endoscope can be operated and / or handled in a similar way to conventional endoscopes. For example, the handle can completely encompass at least a section of the housing relative to a longitudinal axis of the handle and / or relative to a longitudinal axis of the housing. The handle can define a handle interior that is completely surrounded by an end face and / or a lateral surface and in which at least a section of the housing is arranged when the base module is inserted. The handle can be at least partially cylindrical. The housing can be at least partially cylindrical.

[0040] Furthermore, in the manageable state, the handle can be arranged at least partially distally with respect to the housing. For example, a circumference of the base module can be larger in the region of the housing than distally of the housing. The housing and / or the handle can be designed such that the handle can be at least substantially grasped by a user's hand, or the handle can be substantially enclosed by the hand. The handle can also be designed such that the handle can be partially grasped by the hand. Distal with respect to the housing, the circumference can be, for example, 0.1, 0.2, 0.3, 0.4, 0.5, or 0.6 times the circumference in the region of the housing. In particular, the section of the handle arranged distally with respect to the housing can be designed like a pen. "Pen-like" can mean that the section can be grasped by the user as if it were a pen used for writing.Accuracy can be increased with this type of grip. The endoscope can be aligned more easily, more precisely, and / or more accurately, for example, to an anatomical structure. The user has greater sensitivity when positioning an elongated object when gripping it like a pen for writing than when grasping it with one hand and / or clenching it in a fist, for example.

[0041] Furthermore, in the manageable state, the handle can be arranged at least partially proximally with respect to the housing. Furthermore, in the manageable state, the handle can be arranged at least significantly laterally and / or radially outwardly with respect to the housing.

[0042] Furthermore, a longitudinal axis of the handle can correspond to a longitudinal axis of the receiving space. For example, the base module can be arranged substantially coaxially with the handle, particularly when the base module is inserted. This advantageously provides a compact and cost-effective endoscope.

[0043] Furthermore, a longitudinal axis of the handle can be inclined relative to a longitudinal axis of the receiving space. The longitudinal axis of the handle and the longitudinal axis of the receiving space can, for example, enclose an angle of 0° to 179°, in particular of 25° to 145°, preferably of 45° to 120°, and particularly preferably of 75° to 100°. Operating comfort can advantageously be increased. Furthermore, the endoscope can be more ergonomically grippable and / or handled.

[0044] Furthermore, the handle can be a pistol grip. A pistol grip is characterized by particularly high operating comfort and an ergonomic grip. Ergonomic can mean that the user's wrist does not need to be bent or only slightly bent during use of the endoscope. In particular, the pistol grip can be advantageous if the main extension direction of the base module extends at least substantially perpendicular to the user's frontal plane during use.

[0045] Furthermore, the handle can have a smaller diameter than the housing. Advantageously, the diameter of the handle can be designed such that the endoscope, in particular the handle, can be easily and comfortably grasped by the user. The handle can have sections with different diameters, with at least one section having a diameter smaller than the diameter of the housing.

[0046] Furthermore, the handle can have an ergonomic shape. A high level of comfort can be achieved. In addition, it can be ensured that the endoscope can be handled by the user over an extended period of time. An endoscope that is ergonomic for the user can be provided. The ergonomic shape can be a shape adapted to a human hand. The handle can have shaping elements whose size, spacing and / or orientation are adapted to a human palm and / or to the palmar side of at least one human finger. This information relates in particular to the average anatomy of an adult human, for example a woman and / or a man. Furthermore, the handling module and the base module can jointly form an alignment aid that defines a preferred position and / or a preferred orientation of the housing relative to the handling module.The preferred position and / or the preferred orientation can be defined, in particular, with respect to a characteristic of the base module. The preferred position and / or the preferred orientation can, in particular, be a radial preferred position and / or preferred orientation. Alternatively or additionally, the preferred position and / or the preferred orientation can, in particular, be an axial preferred position and / or preferred orientation. The radial preferred position and / or preferred orientation can, in particular, relate to the position of the longitudinal axes relative to one another. For example, the base module can be designed asymmetrically. The alignment aid enables repeatable and error-free insertion of the base module.

[0047] In addition, the alignment aid can have at least one guide slat and a guide groove corresponding to the guide slat. In some embodiments, the guide slat and / or the guide groove can extend along the longitudinal axis of the housing and / or the handle. Furthermore, multiple guide slats and / or guide grooves can be provided. For example, the alignment aid can comprise two, three, four, five, and / or six guide slats and / or guide grooves. Guide slats and / or guide grooves are characterized by particularly secure and / or reliable guidance. The base module can be guided particularly securely in the handling module. Furthermore, a high level of operational reliability can be achieved.

[0048] Furthermore, the base module can comprise at least one actuating element, by means of which at least one function of the base module can be controlled, and the handling module can comprise at least one operating element which, in the manageable state, acts on the actuating element such that operation of the operating element, in particular by the user, causes the actuating element to be actuated. The base module can comprise one, two, three, four, five, or six actuating elements and / or the handling module can comprise one, two, three, four, five, or six operating elements. In particular, the base module can comprise more actuating elements than the handling module comprises operating elements.A controllable function of the base module can include, for example, an image recording function, in particular a recording start, a recording stop, and / or a recording frequency; an illumination function, in particular an illumination light wavelength and / or an illumination light intensity; a base module mode, comprising, for example, a white light mode, a multi- and / or hyperspectral mode, a red light mode, a blue light mode, a green light mode, a video mode, a guidance mode in which an application is supported by guidance elements displayed together with the image data; and / or a focusing mode; a control of an actuator, in particular an actuator configured to move at least a portion of the base module; and / or a cooling function, in particular of the base portion. Action can include contactless action.The actuating element can, for example, comprise a sensor that at least partially detects a movement of the operating element. For example, a switching position of the operating element at which the action can be brought about can also be detected. Alternatively or additionally, the operating element can be provided such that it acts mechanically on the actuating element. Several switching positions, each of which can be actuated, can be provided for each operating element and / or actuating element. The operating element can comprise a knob, a key, a switch and / or the like. In particular, the operating element can be mounted radially in the handle, in particular in the base body. The handle, in particular the base body, can comprise an operating element guide arrangement. In particular, the operating element guide arrangement can comprise a linear guide.Advantageously, the handle does not need to include an opening to the base module that is designed to allow operation by the user.

[0049] In addition, the operating element can be rotatable, and actuation of the operating element can occur according to the rotational position of the operating element. Advantageously, a function can be gradually adjustable. This can be particularly advantageous in connection with adjusting the illumination intensity, controlling the movable portion of the base module, and / or a focal plane of the at least one image sensor.

[0050] In addition, the actuating element and / or the operating element can comprise at least one magnet. Actuation and / or actuation detection and / or actuation transmission can be based on a magnetic force. In particular, the magnet can be a permanent magnet. Magnets can be inexpensive components available in large quantities. The endoscope, in particular the handling module, can be manufactured cost-effectively and / or be simple in design.

[0051] Furthermore, the actuating element can comprise a Hall sensor. Hall sensors are particularly characterized by their compact size, their resistance to interference, such as liquids, dust, dirt, high and / or low temperatures, and / or low and / or high brightness, and / or their ability to switch quickly. Furthermore, Hall sensors can be inexpensive to purchase and / or operate. Advantageously, a reliable and / or error-resistant endoscope can be provided.

[0052] In addition, the base module can comprise at least two functionally identical actuating elements that are arranged at different circumferential positions, in particular opposite one another with respect to a longitudinal axis of the receiving space, and that are each configured to interact with the operating element. For example, the base module can be rotatable by 180° about the longitudinal axis of the housing and can be inserted into the handling module in the relevant rotational position. This can be particularly advantageous if the base module is designed asymmetrically, at least in sections. Advantageously, a handling module for operating the base module can be provided in at least two rotational positions of the base module, in particular without requiring rotation of the handling module in this regard. For example, the user can detach the base module and remove it from the handling module.The user can then rotate the base module around its longitudinal axis, in particular by 180°, and insert and / or fix the base module in the new rotation position into the handling module.

[0053] The base module can further comprise a shaft with a distal section and a proximal section, wherein the proximal section is attached to the housing. The distal section is particularly designed to be introduced into and / or located in a cavity to be examined in an operating state, for example during the diagnostic and / or therapeutic action. The proximal section is particularly designed to be arranged outside the cavity to be examined in an operating state, for example during the diagnostic and / or therapeutic action. “Distal” is to be understood, in particular, during use, facing towards a patient and / or away from a user. “Proximal” is to be understood, in particular, during use, facing away from a patient and / or away from a user. In particular, proximal is the opposite of distal. The shaft can be an elongated object.Furthermore, the shaft can at least partially and preferably at least largely form the distal section. For example, the shaft can have a smaller diameter than the housing. The shaft can be configured to be introduced into a body cavity of a patient. The shaft can have a diameter, in particular a main diameter, which significantly defines the shaft, for example from 1 mm to 50 mm, in particular from 4 mm to 25 mm, preferably from 7 mm to 15 mm. The shaft can be arranged coaxially with the longitudinal axis of the housing. Furthermore, the shaft can be rigid and / or flexible. In particular, the distal section can be provided to be flexible, controllable and / or bendable. In particular, the shaft can comprise mechanical elements that make the shaft controllable. The shaft can extend along the main extension direction of the base module.In particular, the shaft can significantly define the main extension direction. The shaft can, for example, comprise 20% to 95%, in particular 40% to 90%, preferably 60% to 85%, of a main extension of the base module along the main extension direction. In addition, the shaft can comprise the heat pipe and / or the line. In particular, the heat pipe and / or the line can extend along the shaft, in particular from the distal section to the proximal section. The heat pipe and / or the line can protrude beyond the proximal section, in particular into the housing. The line can be connected to the control electronics. In particular, the line can be configured to connect controllable and / or electronic elements to the control electronics.

[0054] Furthermore, the shaft can be designed as an interchangeable shaft. The interchangeable shaft can be detachably connected to the base module and / or the handling module. In particular, the endoscope can comprise a connection unit, in particular a connector, which is designed to connect electronic elements of the interchangeable shaft to the control electronics. Different interchangeable shafts, or interchangeable shafts that implement different functionalities, can also be provided. Advantageously, the interchangeable shaft can be detachably connected to the housing without the need for tools. Furthermore, the distal section can comprise a camera and / or a light source. The camera can comprise the image sensor and / or the optics. The image sensor can be, for example, a CCD chip or a CMOS chip. According to some embodiments, the camera can comprise more than one image sensor. For example, the camera can be a stereo camera and / or comprise two image sensors.In some embodiments, the camera can be configured to generate digital image data. Alternatively or additionally, the camera can be configured to generate analog image data. In particular, the camera can comprise a computing unit configured to generate digital image data from analog image data. The light source can comprise the luminous element. The light source can further comprise a plurality of luminous elements. According to some embodiments, the light source can comprise an LED and / or a laser diode. At least one of the luminous elements can be a white-light luminous element, in particular a white-light LED. The control electronics can be configured to supply the light source with application-specific and / or operating-state-specific electrical energy.

[0055] Application-specific / operating-state-specific can mean, in particular, that a luminous intensity and / or an emission spectrum of the luminous element can be adjusted with respect to an application / operating state. In some cases, this can be achieved by mixing light from different luminous elements and / or selectively activating and / or deactivating certain luminous elements for different applications / operating states. The luminous intensity can be adjustable automatically and / or by the user. The connection unit can be configured to connect the camera to the control electronics and to transmit image data from the camera to the control electronics.Advantages can arise from the fact that the distal section comprises the camera and / or the light source. It can be particularly advantageous that light received by the distal section does not have to be guided to a proximal end of the shaft by means of optical elements such as glass fibers, light guides, rod lenses or the like. This can, for example, reduce and / or avoid imaging errors that can occur due to the light being guided along the shaft. Furthermore, small shaft diameters can be achieved because the shaft only has to contain electrical lines and no optical components. Furthermore, there is no need to provide a light guide that guides illumination light to the distal section. Overall, high image quality can be achieved with a small shaft diameter.Furthermore, the distal section can comprise at least one optical element that defines a main viewing direction, wherein the main viewing direction is inclined with respect to a longitudinal axis of the shaft. Furthermore, the main viewing direction can coincide with the main extension axis and / or the longitudinal axis of the housing. The optical element can be, for example, a lens of the optics. Furthermore, the optical element can be transparent to light such that light can be admitted into the distal section from outside the shaft virtually unchanged, in particular with regard to spectral components and / or an image plane. According to some embodiments, the main viewing direction can enclose an angle with the longitudinal axis of the shaft and / or the main extension axis. The included angle can be the reference measure for an angular specification of the main viewing direction. This can mean that if the main viewing direction is parallel to the longitudinal axis of the shaft, the main viewing direction is 0°.The main viewing direction can generally be 0° to 90°. Preferred main viewing directions are at least 0°, 10°, 20°, 30°, 40°, 45°, 60°, 75°, and 90°. The main viewing direction can be oriented within an angular range of + / - 5° starting from one of these values. The image sensor can be arranged orthogonally to the main viewing direction. According to further embodiments, the image sensor can be arranged such that the longitudinal axis of the shaft extends partially along the image sensor. The inclined main viewing direction can expand the area that can be imaged and / or viewed by the endoscope. In particular, the base module can be rotated 180° around its longitudinal axis and reinserted into the handling module. This can be particularly advantageous if the main viewing direction is inclined. For example, the user can enlarge the observation space in this way, whereby the handling module can be used in a preferred orientation.

[0056] Furthermore, the endoscope can comprise a supply cable that is connected and / or connectable to the base module. The supply cable can be configured to transmit electrical energy, analog and / or digital data, in particular image data and / or control signals. Connectable can mean that the supply cable can be connected easily and / or quickly. In particular, no specialist personnel need be required for the connection. Advantageously, there does not have to be a connection between the handling module and the supply cable. In particular, the supply cable can be connected and / or connectable independently of the handling module. Furthermore, the supply cable can be permanently connected to the base module. Advantageously, tightness, in particular gas tightness and / or fluid tightness, can be ensured. In particular, the supply cable can be configured to be sterilized and / or autoclaved.Incorrect operation can also be prevented.

[0057] In addition, the base module and the supply cable can jointly form a connector. Advantageously, the connector can be designed independently of the handling module. This allows for a simplified design and / or the use of differently designed handling modules.

[0058] Furthermore, the supply cable can be a coaxial cable. Furthermore, the base module, in particular the control electronics, can comprise a serializer and / or filter configured to bundle multiple data signals and / or power-related signals and / or currents into a differential pair and / or to provide communication and / or electrical power via a differential pair. By providing the coaxial cable, there is no preferred insertion orientation of the supply cable. Operation of the endoscope, in particular insertion of the supply cable, can be simplified and quick. Furthermore, the risk of incorrect operation can be reduced. In particular, insertion of the supply cable does not require any special attention from the user.

[0059] Furthermore, the supply cable can be rotatable relative to the base module when connected. Rotatable can mean, in particular, that the supply cable is mounted so that it can rotate. For example, the supply cable, in particular the coaxial cable, can only be secured against axial displacement. Advantageously, there is no preferred orientation of the supply cable relative to the base module. The base module can be rotatable during operation. In particular, the risk of twisting and / or knotting of the supply cable can be at least reduced. Operating safety can thereby be increased.

[0060] In addition, a cable outlet direction of the supply cable from the base module can be inclined relative to a longitudinal axis of the base module. Cable outlet direction can mean that the supply cable, in a connected state, includes a rigid section in a close range to the base module, which deflects an extension direction of the supply cable. For example, this can prevent the supply cable from getting in the way of the user and / or the user from damaging the supply cable. This can improve the operational reliability and / or durability of the endoscope.

[0061] Furthermore, the base body can form an opening on its proximal side through which the base module can be inserted into the receiving space. In this context, "insertable" can mean, in particular, "slidable."

[0062] In particular, the opening may have a diameter that corresponds at least to the diameter of the base module, in particular the housing.

[0063] Advantageously, the base module can be grasped by the housing for insertion. In particular, it can be avoided that the base module must be grasped by the shaft. Gripping the shaft can, for example, lead to plastic deformation of the shaft and / or damage to components enclosed by the shaft, in particular rod lenses. Furthermore, insertion can be carried out quickly and easily by a user. In particular, insertion can be carried out during a treatment and / or examination of a patient.

[0064] Furthermore, the control electronics can be enclosed in a gas-tight housing. In particular, the housing can enclose the control electronics in a gas-tight manner. This advantageously allows for the provision of a sterilizable, easily sterilized, and / or autoclavable base module.

[0065] Furthermore, the handling module can be configured to be autoclaved and / or sterilized separately from the base module. The handling module can be provided in sterile outer packaging. The user can remove the handling module from the sterile outer packaging. This enables, for example, a quick and reliable change of the handling module, in particular without the user having to worry about the sterilization status of the handling module. The handling module can always be available and / or quickly ready for use. This can mean that the user can, for example, have various sterile handling modules at their disposal during patient treatment. The base module can be inserted into the handling module as needed. However, the user does not require multiple base modules, which can reduce treatment costs.After a treatment, the associated handling module and the associated base module can be separately autoclavable and / or sterilizable. This allows them to be provided ready for further treatment. Several sterile single-use products can be provided, each of which can comprise a sterile outer packaging and at least one handling module. The sterile single-use product can, in particular, be storable and / or able to be kept in stock.

[0066] Furthermore, the handling module can be made at least partially and in particular at least largely from plastic, in particular a polymer material. The expression “at least largely” should be understood to mean in particular at least 55%, more preferably at least 65%, more preferably at least 75%, particularly preferably at least 85% and most preferably at least 95%, and advantageously completely, in particular with reference to a volume and / or a mass of a component. The plastic can be and / or comprise a thermoplastic and / or a thermosetting plastic and / or an elastomer. Furthermore, the base body can be made from sustainable materials, in particular degradable and / or recyclable materials.The plastic can be a bioplastic and / or a bioplastic, for example a plastic based on renewable raw materials and / or a plastic that is biodegradable, and / or comprise such. Advantageously, a cost-effective handling module can be provided. Furthermore, the plastic can have a heat-insulating effect, particularly compared to a metal. The handling module can therefore be easier to handle for the user. In particular, heating of the handling module, in particular of the handle, beyond a threshold temperature that the user finds just comfortable can be prevented. This allows a larger number of lighting elements and / or more powerful lighting elements to be provided, or to use a higher power when operating lighting elements.Particularly in emergency situations, this allows a higher maximum illumination intensity to be used at least temporarily without the temperature making handling impossible because the user can no longer hold the endoscope securely due to its heating.

[0067] In addition, the base body can be manufactured by injection molding and / or additively. The base body can be formed integrally and / or in one piece. In particular, the base body can be an injection-molded part. In further embodiments, the base body can be formed in two parts and / or several parts. The base body can in particular be permanently assembled, for example if the base body is formed in two parts and / or several parts. Furthermore, the base body can be characterized by inexpensive production and / or low material usage. Particularly simple manufacturability can be achieved in particular if the base body can be demolded as a whole, in particular in a direction parallel to the main direction of extension and / or parallel to the longitudinal axis of the base body.In some embodiments, the base body may be made of two half-shells that are, for example, glued and / or welded together, for example by means of ultrasonic welding.

[0068] Furthermore, the handling module can be a single-use product. In particular, the handling module can replace and / or eliminate the sterile disposable sheath. In particular, providing the sterile disposable sheath can be time-consuming. By eliminating the sterile disposable sheath, significant time savings can be achieved. Furthermore, the entire process can be simplified and / or the operation of the endoscope can be more economical. Furthermore, fewer personnel may be required to operate the endoscope.

[0069] Furthermore, in the operable state, a longitudinal axis of the base module can coincide with a longitudinal axis of the receiving space. In particular, the longitudinal axis of the base module can coincide with the main extension axis and / or with the longitudinal axis of the shaft. In particular, the base module can be designed to be rotationally symmetrical, particularly with regard to its shape. The endoscope can have a simple construction with minimal installation space requirements.

[0070] In addition, the handling module can have at least one sealing element that seals against the base module in the operable state. In particular, the receiving space can not be completely filled by the base module in the operable state. In other words, there can be a free space between the base module and walls of the handling module. The at least one sealing element can be designed to seal the receiving space in a gas-tight and / or fluid-tight manner. For example, the handling module can have the at least one sealing element only on one side, in particular an end face and / or a distal side. The at least one sealing element can seal against the base module in particular on a distal side of the handling module. In particular, the sealing element can seal against the base module in a close region around the shaft.Contamination of the interior of the handling module and / or the base module, in particular the housing of the base module, can advantageously be prevented and / or at least significantly reduced. Furthermore, it is possible to prevent, for example, fluid from flowing along the shaft into the space between the handling module and the base module. The endoscope can thus be more cost-effective and reliable in operation and can be used over a longer period of time. Furthermore, cooling of the base module can be unaffected and / or only slightly impaired.

[0071] The handling module can further comprise at least one air inlet at a distal portion of the handling module and at least one air outlet at a proximal portion of the handling module, wherein the at least one air inlet is connected to the at least one air outlet. This allows air circulation to be achieved, which can be particularly advantageous for cooling the base module by convection. In particular, air circulation can be achieved in the free space. In particular, it can be ensured that the control electronics can be maintained below a limit temperature range. Above the limit temperature range, a function of the control electronics can be restricted. Furthermore, waste heat can be dissipated, for example, from the distal portion of the shaft, in particular by means of the heat pipe along the shaft, to the housing. The waste heat can, in particular, heat the housing.In this regard, the housing can function as a heat sink. Furthermore, the base module can comprise a further heat sink, for example, a heat sink, which can include cooling fins, and / or a copper plate. Furthermore, the base module can comprise a section that has an enlarged surface area, for example, due to the provision of cooling fins, and / or is made of a material that has good heat-transfer properties. The air inlet can be configured to admit air, in particular cooling air, into the receiving space, wherein the air can cool the base module, the control electronics, the housing, and / or the further heat sink. Advantageously, control electronics, a camera, and / or a light source with higher power can be provided. Furthermore, the operation of the endoscope can be more comfortable for the user.In particular, heating of the handling module, in particular of the handle, can be prevented and / or reduced.

[0072] Furthermore, it can be particularly advantageous to provide the air inlet and / or the air outlet if the handling module is made of plastic. The heat-insulating effect of the plastic can significantly reduce cooling of the base module. By providing the air inlet and / or the air outlet, cooling of the base module can be ensured, particularly despite the provision of a plastic handling module. Advantageously, the handling module and the base module can exhibit synergy through the provision of the cooling effect. The handling module can be inexpensive and / or convenient, while the base module can be powerful at the same time.

[0073] In addition, the at least one air inlet can be connected to the at least one air outlet via an air duct, wherein, in the handleable state, a radial inner surface of the air duct is defined by the housing. Furthermore, a radial side surface of the air duct can be defined by the alignment aid, in particular by the at least one guide lamella. In addition, a radial outer surface of the air duct can be defined by the handling module. The air duct can extend, in particular, along a large part of the housing. For example, the air duct can extend along at least 30%, in particular at least 60%, and / or preferably at least 80% of the housing, in particular along the longitudinal axis of the housing. Advantageously, the housing can be cooled particularly efficiently. By directing the air along the housing, a high cooling performance can be achieved.

[0074] Furthermore, the air duct can be hollow-cylindrical. This can mean that the air duct extends substantially around the entire circumference of the housing and / or the base module. In particular, the air duct can surround and / or enclose the housing. The surface area of ​​the base module, in particular the housing, intended for cooling can be raised and / or particularly efficient cooling can be achieved.

[0075] In addition, the handling module can comprise a coolant communication interface via which a cooling fluid can be introduced into the receiving space. The cooling fluid can be conducted to the coolant communication interface, in particular by means of hoses, and / or can be discharged from the coolant communication interface. In particular, the system can comprise a cooling fluid conveying device. The cooling fluid conveying device can comprise a pump and / or a heat exchanger. For example, the cooling fluid can be conveyed to the handling module in a first state by means of the pump. In the receiving space, the coolant can in particular come into contact with the base module or absorb enthalpy of the base module, in particular in order to cool the base module. By absorbing the enthalpy, the cooling fluid can reach a second state. Furthermore, the cooling fluid can be conveyed to the cooling fluid conveying device, in particular to the heat exchanger.The heat exchanger can be configured to transfer the cooling fluid from the second state to the first state. The cooling fluid can be a special cooling fluid with application- and / or operation-specific properties. Furthermore, the cooling fluid can be water, in particular distilled water. Cooling by means of a cooling fluid can, in particular, achieve better cooling performance than cooling by means of air and / or convection.

[0076] Furthermore, in the handleable state, the receiving space can be sealed from the environment. In particular, this can achieve a better and / or more efficient cooling effect. For example, cooling air can be introduced into the receiving space via an air inlet duct. For example, the air can be introduced at a pressure greater than the ambient pressure. The seal can effect air circulation in such a way that the air can be forced out of at least one air outlet. As a result, the air circulation can be provided more efficiently and / or in a more adjustable manner.

[0077] Furthermore, the endoscope can comprise a cooling module, wherein the base body defines a cooling module receiving space into which the cooling module can be inserted, and wherein, in an inserted state of the cooling module in the handleable state, the cooling module and the base module are in at least thermal contact. Advantageously, the cooling module can be provided for cooling the base module. Should the cooling performance of the cooling module decrease during operation of the endoscope, the cooling module can be replaced by another cooling module that can have the same properties as the cooling module. In particular, the user can replace the cooling module with the additional cooling module. The additional cooling module can subsequently make the base module efficiently coolable again. In particular, the cooling module can be designed such that it can absorb and / or store a large enthalpy in a small installation space.

[0078] Advantageously, good cooling performance can be achieved.

[0079] Furthermore, the cooling module can comprise and / or be designed as a latent heat storage device. The latent heat storage device can be configured to store absorbed thermal energy, in particular heat, in the form of latent heat. For example, the absorbed energy can be stored by a phase change, for example, from solid to liquid, of a medium. The latent heat storage device can comprise a phase-change material. Advantageously, good heat storage properties can be achieved while simultaneously requiring a small installation space.

[0080] In addition, the cooling module receiving space can open into the receiving space, and the cooling module can be brought into physical and thermal contact with the base module when inserted into the cooling module receiving space. This allows for particularly efficient thermal energy transfer. The cooling module can be pressed against the base module during insertion, establishing both physical and thermal contact. The cooling module can rest on the side of the base module. Furthermore, the design can be simpler, in particular since no additional heat-conducting elements are required. The endoscope can be more cost-effective and efficient.

[0081] In addition, the base module and / or the cooling module can have a heat-conducting, deformable element that rests against the cooling module or the base module in the handleable state and in the inserted state. If, for example, two rigid bodies are brought into contact with each other for heat exchange, heat-insulating air gaps can form between the two bodies. This can reduce and / or impair heat transfer. By providing the heat-conducting element, the air gaps can be filled, for example. This can mean that the surface area significantly involved in heat transfer is increased. In principle, a heat exchange surface can be increased. Consequently, the efficiency of the endoscope and / or a cooling effect can be increased. In particular, a more powerful base module can be provided. Furthermore, user comfort can be improved.The heat-conducting, deformable element can be made of, for example, a heat-conducting rubber. Alternatively or additionally, a deformable metallic structure can be provided.

[0082] Furthermore, in the manageable state and in the inserted state of the cooling module, the cooling module can apply a force to the base module. In particular, an interaction with the deformable element can be achieved. For example, the deformable element can be subjected to a force such that the heat exchange surface is increased and / or thermal contact is improved. Furthermore, the heat exchange surface can generally be increased. Consequently, the efficiency of the endoscope and / or the cooling effect can be increased. In particular, a more powerful base module can be provided.

[0083] Furthermore, the handling module can be configured to be attached to a holder of a medical robot and to make the base module manageable for the robot. Furthermore, the handling module and the holder can jointly form a single component. Furthermore, the handling module can be permanently attached and / or attachable to the robot. Advantageously, the base module can be made quickly and efficiently manageable for the robot. In particular, the base module can be quickly and efficiently replaced with another, in particular differently designed, base module.

[0123] Fig. 1 shows a system 10 comprising a supply unit 12, a display unit 14, an endoscope 20, and a sterile single-use product 134. The endoscope 20 comprises a base module 22. The base module 22 has a housing 24 and control electronics 26 which are encased in a gas-tight manner.

[0124] Furthermore, the endoscope 20 comprises a handling module 28. The

[0125] The handling module 28 is configured to make the base module 22 manageable. Furthermore, the handling module 28 comprises a base body 30 that defines a receiving space 32 for the base module 22. The base module 22 can be inserted into the receiving space 32 of the handling module 28 by a user to create a manageable state. In the illustrated case, the base module 22 is inserted into the receiving space, and the endoscope 20, in particular the base module 22, is manageable.

[0126] The user can generally remove the base module 22 from the handling module 28 and insert another base module into the receiving space 32 of the handling module 28. This could make the additional base module manageable.

[0127] The handling module 28 and the base module 22 together form a fixing mechanism 34, shown only schematically, by means of which the base module 22, in particular the housing 24, can be releasably fixed to the handling module 28. In particular, the base module 22 can be removed and / or fixed to the handling module 28 without the need for tools.

[0128] The handling module 28 is configured to make the base module 22 manageable and operable for the user. By inserting the base module 22 into the receiving space 32, an operable state can be established. In this regard, the base body 30 comprises a handle 44. The handle 44 has an ergonomic shape not shown in Fig. 1. In the manageable state, the handle 44 completely encompasses the housing 24. A longitudinal axis of the handle 44 corresponds to a longitudinal axis of the receiving space 32. These longitudinal axes coincide accordingly on the axis 86 shown in Fig. 1. In the operable state, a longitudinal axis of the base module 22 also coincides with the longitudinal axis of the receiving space 32. A main extension direction of the base module 22 and / or the receiving space 32 and / or the handle 44 runs parallel to the aforementioned longitudinal axes or to the axis 86.

[0129] The handling module 28 is made at least partially, and in particular at least largely, of plastic. In addition, the base body 30 is manufactured by injection molding. Alternatively, the base body 30 can be manufactured additively, or by an additive manufacturing process. In particular, the handling module 28 is manufactured inexpensively and / or with low material expenditure. In the present case, the handling module 28 is intended for single use. It could be referred to as single-use. In addition, the handling module 28 and / or the base module 22 are configured to be autoclaved and / or sterilized separately. In particular, the handling module 28 is configured to be autoclaved and / or sterilized separately from the base module 22.

[0130] Furthermore, the handling module 28 comprises operating elements 64, two of which are shown as examples in Fig. 1. However, it is understood that a different number of operating elements 64 can be provided. The operating elements 64 are arranged on the handle 44 and / or are part thereof. The user can operate the base module 22 using the operating elements 64. The operating elements 64 act in particular indirectly. In other words, the operating elements 64 are not part of the base module 22, but rather act on it in a manner that enables the user to operate the base module 22 by operating the operating elements 64.

[0131] The base module 22 comprises a shaft 70 with a distal section 72 and a proximal section 74, wherein the proximal section 74 is attached to the housing 24. The distal section 72 comprises a camera 78 and / or a light source 80. The shaft 70 is, for example, 40 cm long and has, for example, a 2 cm diameter. A longitudinal axis of the shaft 70 coincides with the longitudinal axis of the base module 22, the longitudinal axis of the receiving space 32, the longitudinal axis of the handle 44, and the axis 86.

[0132] The shaft 70 comprises a heat pipe (not shown) and lines (not shown). The heat pipe and / or the lines extend along the shaft 70, in particular from the distal section 72 to the proximal section 74. The heat pipe and / or the lines extend beyond the proximal section 74 into the housing 24 of the base module 22 and / or into the handling module 28 or are connected and / or connectable to the housing 24 and / or the base module 22 via suitable connections. The lines are connected to the control electronics 26. The lines are configured to connect controllable and / or electronic elements to the control electronics 26.

[0133] In particular, the lines connect the camera 78 and / or the light source 80 to the control electronics 26. The heat pipe conducts waste heat generated during operation of the camera 78, the light source 80, and / or the other electronic components along the shaft 70 to the housing 24 of the base module 22. The distal section 72 comprises an optical element 82 that defines a main viewing direction 84. The main viewing direction 84 is inclined with respect to the axis 86 and is, in particular, 45°. The optical element can, for example, be a lens that is installed at a specific angle relative to a longitudinal axis of the shaft 70.

[0134] The camera 78 includes an image sensor (not shown), which may be, for example, a CCD chip or a CMOS chip. In some embodiments, the camera 78 may be a stereo camera and / or include two image sensors. The camera 78 is configured to generate image data.

[0135] The light source 80 comprises a lighting element (not shown). The light source 80 can also comprise multiple lighting elements. The lighting element is, for example, an LED, in particular a white light LED. The light source 80 can be multimodal and provide illumination light optionally in different spectral ranges. Furthermore, the light source 80 can be configured to provide illumination light continuously and / or in pulsed form. The light intensity of the light source 80 can be adjusted automatically and / or by the user. The control electronics 26 are configured to supply the light source 80 with application-specific and / or operating state-specific electrical energy. The lines are configured to transmit the image data from the camera 78 to the control electronics 26.

[0136] In other embodiments, the supply unit 12 can also supply illumination light for the endoscope 20. For example, a lighting device can be provided that supplies illumination light for imaging. The endoscope 20 can be coupled and / or connected to the lighting device via a fiber optic cable. The endoscope 20 can then have a suitable fiber optic element in its shaft 70, by means of which illumination light can be guided to the distal end 72. The light source 80 can then be omitted or provided additionally. In other embodiments, a separate lighting device and / or illumination light source can be provided.

[0137] In the present case, the base module 22 is also connected to a supply cable 88. In some embodiments, the supply cable 88 can be permanently attached to the base module 22 and / or be part thereof. In the present case, the supply cable 88 is detachable. The supply cable 88 is a coaxial cable and is configured to be sterilizable and / or autoclavable. In a connected state, the supply cable 88 is rotatable relative to the base module 22. In particular, the supply cable 88 is rotatable about the longitudinal axis of the base module 96. The base module 22 includes a supply cable bearing configured for this purpose (not shown). The supply cable 88 is connected to the supply unit 12 and is configured to supply the base module 22, in particular the control electronics 26, with electrical energy and to enable data exchange.In particular, image data generated by camera 80 is transmitted to supply unit 12 via supply cable 88. Supply unit 12 is also connected to display unit 14. Display unit 14 is configured to display the image data to the user.

[0138] The user can use the endoscope 20 for a diagnostic and / or therapeutic procedure. For example, they can guide the shaft 70 into a patient's body cavity to view the anatomical structure 16. The anatomical structure 16 is displayed to the user by the display unit 14. It may occur that the user is restricted in performing the diagnostic and / or therapeutic procedure by the main viewing direction 84 of the endoscope 20. Consequently, the user can provide a different base module that defines a different main viewing direction. To do so, the user can remove the base module 22 from the handling module 28 and insert the other base module into the receiving space of the handling module 28 and releasably secure it.

[0139] The sterile single-use product 134 comprises an outer packaging 136 and an additional handling module 29. In the exemplary case, the additional handling module 29 is different from the handling module 28. The two handling modules 28, 29 implement different functionalities in the handleable state of the base module 22. The additional handling module 29 is packaged in a sterile state in the outer packaging 136.

[0140] It is understood that the handling module 28 may also have been packaged in a similarly designed sterile outer packaging prior to its use in the endoscope 20. The handling module 28 is advantageously part of such a single-use product. It is unpacked by the user or other clinical personnel only immediately before use, for example, in preparation for a procedure, and is therefore sterile. Additional sterilization is eliminated, as is the need for draping. The user can then insert the base module 22 into the handling module 28, thus making the base module 22 manageable.

[0141] Analogously, the user can remove and / or prepare the additional handling module 29 from the outer packaging 136. For example, the handle of the handling module 28' is a pistol grip, which can be advantageous with regard to the action. Furthermore, the user can detach the base module 22 from the handling module 28 and remove the base module 22 from the handling module 28. The user can then insert the base module 22 into the additional handling module 29, in particular into a receiving space thereof. The handling module 28 can be disposed of or thrown away by the user. Furthermore, the base module 22, in particular together with the supply cable 88, can be sterilized and / or autoclaved before the user inserts the base module 22 into the handling module 28'. Furthermore, the user can releasably fix the base module 22, in particular the housing of the base module 22, to the additional handling module 28 before an endoscope thus created is used.

[0142] In this case, the shaft 70 is firmly connected to the housing 24. The shaft 70 can be formed integrally with the housing 24. Alternatively or additionally, the shaft 70 can be welded or glued to the housing 24, for example. A connection between the shaft 70 and the housing 24 can be vapor-tight.

[0143] In some embodiments, the shaft 70 can be designed as an interchangeable shaft. The shaft 70 designed as an interchangeable shaft can then be detachably connected to the housing 24 without tools. In this way, different interchangeable shafts can be used, which, for example, have different cameras, different light sources, different lengths, different diameters, different materials, etc. and / or define different main viewing directions. In general, different interchangeable shafts can be provided for different applications. Fig. 2 shows a schematic view of the distal end 72 of the shaft 70 in a side view. Some details can be seen in more detail therein. The camera 78 comprises the optical element 82 and an image sensor 148. The optical element 82 defines the main viewing direction 84 of 45°, which is inclined relative to the longitudinal axis of the shaft 70 or the axis 86.In addition, the shaft 70 comprises the light source 80. Furthermore, the shaft 70 comprises a heat pipe 152. The heat pipe 152 extends at least into a close range of the camera 78. Furthermore, the shaft 70 comprises two electronic elements 150, 151. These can be, for example, circuit boards, control processors, circuits, sensors or other components.

[0144] Fig. 3 shows a schematic representation of the base module 22. As mentioned, the system 10 comprises the supply cable 88, which can be connected to the base module 22. The base module 22 and the supply cable 88 together form a connector 90. The supply cable 88 is a coaxial cable 92 and, when connected to the base module 22, is rotatable relative to the base module 22. A part of the supply cable 88 (not shown) can be connected to the supply unit 12. A connector can also be provided for connecting the supply cable 88 to the supply unit 12. This can also establish a rotatable connection. Alternatively, as shown in Fig.1, the connection between the supply cable 88 and the supply unit 12 may be designed differently than the connection between the base module 22 and the supply cable 88, for example as a plug with several contacts arranged next to one another and / or as a plug with a preferred insertion orientation.

[0145] The base module comprises a plurality of actuating elements 62, which are all provided with the same reference numeral for simplicity. The actuating elements 62 can be configured differently and / or control different functionalities of the base element 22. For example, they can be used to actuate the camera 78 and / or the light source 80 and / or to adjust a light intensity and / or light color.

[0146] Fig. 4 shows a schematic representation of the handling module 28 and the base module 22 before the base module 22 is inserted into the receiving space 32 of the handling module 28. The handling module 28 has a plurality of operating elements 64 arranged on an outer side of the base body 30. For the sake of simplicity, the operating elements 64 are all provided with the same reference numeral, but can be designed differently. For example, at least one of the operating elements 64 can be designed as a push button. Furthermore, at least one of the operating elements 64 can be designed as a rotary knob. In addition, at least one of the operating elements 64 can be designed as a slide control. The operating elements 64 can be part of an operating assembly 65. The operating assembly 65 can comprise its own housing that is connected to the base body 30. The operating assembly 65 can be manufactured separately from the base body.In the present case, for example, the base body 30 is an injection-molded part into which the operating module 65 is installed.

[0147] In other embodiments, the operating elements 64 can be formed integrally with the base body 30. These can be connected to adjacent material, for example, via webs and / or film hinges and / or the like, and can be manufactured in a single injection-molding step.

[0148] The operating elements 64 are arranged such that they act on the actuating elements 62 in at least one insertion position of the base module 22. In particular, a clear, in particular one-to-one, assignment can be provided, so that a specific functionality of the base module 22 can be controlled by means of a respective operating element 64, in that the operating element 64 acts on an actuating element 62 assigned to the functionality.

[0149] As can be seen in Fig. 3, actuating elements 62 are arranged at different circumferential positions of the housing 24 of the base module 22. In the case shown, two groups of actuating elements 62 that are identical and / or analogous to one another are arranged at opposite positions of the housing 24. This makes it possible to insert the base module 22 into the receiving space 32 in two different orientations, with one of the groups of actuating elements 62 interacting with the operating elements 64 for each of the two orientations. If, as in the present case, an angular main viewing direction 84 is provided, two different viewing directions can be realized with the same base module 22 for a given hand-holding position of the handling module 28, for example +45° and -45°, depending on the orientation. The receiving space 32 extends, for example, along 90% of a length of the handling module 28. Fig.Fig. 5 shows a simplified schematic view of the handling module 28 viewed from its proximal side 98. Reference is also made below to Fig. 5. The base body 30 forms an opening 100 on its proximal side 98, through which, in particular, the base module 22 can be inserted into the receiving space 32. Furthermore, the handling module 28, in particular the base body 30, forms a distal opening 154 on its distal side 156. The distal opening 154 is configured such that the shaft 70 can be inserted through the distal opening 154.

[0150] The receiving space 32 has a circular cross-section. The housing 24 of the base module 22 has a circular cross-section. In an inserted state, the housing 24 is arranged concentrically with the receiving space 32. The receiving space 32 has a cylindrical section. The housing 24 has a cylindrical section. In the inserted state, the cylindrical section of the housing 24 is arranged in the cylindrical section of the receiving space 32.

[0151] In principle, base modules can also be inserted into a receiving space for handling modules during factory assembly. In this context, the user may be different from the end user. For example, the user could be an assembly worker in a factory. It is also conceivable that the user operates a machine designed to insert base modules into a receiving space for handling modules.

[0152] Fig. 6 shows a schematic representation of an endoscope 220. The endoscope 220 is generally designed analogously to the endoscope 20 described above. The differences will be discussed primarily below. The endoscope 220 comprises a base module 222 and a handling module 228. The base module 220 can be inserted into a receiving space 232 of the handling module 28 and is shown in an inserted state in Fig. 6. The base module 222 can be inserted into the receiving space 232 from a proximal side of the handling module 228 through an opening. The handling module 228 has a handle 244. In the present case, the handling module 228 has a base body 230 which forms the handle 244. The handle 244 is arranged at least in sections distally with respect to a housing 224 of the base module 222. The 244 has a first diameter 252. The housing 224 has a second diameter 254.The first diameter 252 is smaller than the second diameter 254.

[0153] Fig. 6 shows the endoscope 220 in a user's hand. It can be seen that the portion of the handle 244 arranged distally relative to the housing 224, or the handle 244 as a whole, is designed to be pen-like. Pen-like means that the handle 244 is grippable by the user as if it were a pen used for writing. This allows the endoscope 220 to be guided very precisely. Small movements can thus be performed in a controlled manner. The endoscope 220 is suitable, for example, for applications in neurosurgery.

[0154] Fig. 7 shows a schematic representation of an endoscope 320. The endoscope 320 is generally designed analogously to the endoscopes 20, 220 described above. The following primarily discusses the differences. The endoscope 320 comprises a base module 322 and a handling module 328. The base module 320 can be inserted into a receiving space 332 of the handling module 328 and is shown in an inserted state in Fig. 7.

[0155] The handling module 328 comprises a handle 344. The handle 344 is arranged at least partially proximally with respect to the housing 324. In the present case, the handle 344 encloses the housing 324 on a proximal side. According to other embodiments not shown, the base body according to Fig. 5 can form an opening on its proximal side through which, in particular, the base module 22 can be introduced into the receiving space. A longitudinal axis 346 of the handle 344 is inclined with respect to a longitudinal axis 348 of the receiving space 342. The longitudinal axis 348 of the receiving space 342 and the longitudinal axis 346 of the handle 344 enclose an angle of 100°, for example. The handle 344 is a pistol grip. In addition, the handling module 328 comprises two operating elements 364, one of which is shown in more detail in Fig. 8. The operating elements 364 are arranged on the handle 344.The operating elements 364 can be operated, for example, with an index finger and / or a middle finger and / or a ring finger when the handle 344 is gripped, in particular in the manner of a trigger. Fig. 8 shows a further schematic representation of the endoscope 320 from Fig. 7 with a detailed view of the operating element 364 of the endoscope 320. The operating element 364 is coupled to an actuating mechanism 358. The actuating mechanism 358 can also be part of the actuating element 364. The operating element 364 can have at least two operating states. One of the operating states is shown in solid lines, while another operating state is shown in dashed lines. By operating the operating element 364, the actuating mechanism 358 is actuated and, in particular, moved into another actuating state.The actuating mechanism 358 includes, in particular, a lever mechanism 360 configured to guide a movement of the operating element 364 into the vicinity of an actuating element 362 of the base module 322. The movement can be caused by the user, for example, by the user exerting a pressure force on the operating element 364. The operating element 364 can be spring-loaded, in particular into a non-actuated position.

[0156] The actuating mechanism 358 can be coupled to a trigger element 370. The trigger element 370 can also be part of the operating element 364. In this case, the trigger element 370 comprises a magnet 366. The magnet 366 can be a permanent magnet, for example. By operating, in particular pressing, the operating element 364, the trigger element 370 can be moved away from the actuating element 362. As a result, the operating element 364 can act on the actuating element 362 in such a way that an actuation of the actuating element 362 can be effected, in particular by the user.

[0157] In this case, the actuating element 362 comprises a Hall sensor 368. The Hall sensor 368 is configured to detect a movement or a position and / or a change in position of the trigger element 370. For this purpose, the Hall sensor 368 senses a magnetic field of the magnet 366.

[0158] Fig. 9 shows a schematic representation of the handling module 328 in a view parallel to a longitudinal axis of the receiving space 332. A base body 330 of the handling module 328 has two base body parts 340, 342 that are pivotally connected to one another. The base body parts 340, 342 are movable relative to one another to open and close the receiving space 332. When the receiving space 332 is open, the base module 322 can be inserted into the receiving space 332. When the receiving space 332 is closed, the housing 324 of the base module 322 is fixed to the handling module 328.

[0159] The base body 330 has a hinge 350. The hinge 350 can be designed, for example, as a hinge strip that extends parallel to a longitudinal axis of the receiving space 332. In some embodiments, the hinge 350 can be a film hinge. The hinge 350 can then be manufactured in a single manufacturing step together with the two base body parts 340, 342, in particular by means of injection molding and / or additive manufacturing. The base body parts 340, 342 are preferably made of plastic.

[0160] The handling module 328 has a fixing mechanism 334. In this case, the fixing mechanism 334 comprises a locking element 336 that can engage in a locking receptacle 338 to establish a locking state. The locking element 336 and the locking receptacle 338 are each provided on one of the base body parts 340, 342. The fixing mechanism 334 is a clip closure. After inserting the base module 322 into the receiving space 332, the user can fold the two base body parts 340, 342 together and close the fixing mechanism 334. The base module 322 is then fixed in the handling module 328.

[0161] In some embodiments, the base body 330 can be provided on an inner side with at least one elastic heat-conducting element 352, which can be formed, for example, from a heat-conducting elastomer. In the present case, such an elastic heat-conducting element 352 is provided on each of the base body parts 340, 342. When the base module 322 is inserted, the at least one heat-conducting element 352 contacts the housing of the base module 322. This allows waste heat to be dissipated via the at least one heat-conducting element 352. Furthermore, the at least one heat-conducting element 352 can clamp the base module 322, thereby securely holding it in the receiving space 332.

[0162] Fig. 10 shows the handling module 328 in a state in which the receiving space 332 is closed. The two base body parts 340, 342 are closed and locked together by means of the fixing mechanism 334. Fig. 11 shows a schematic representation of a fixing mechanism 34. For example, this can be the fixing mechanism used in Fig. 1. The fixing mechanism 34 for the endoscope 20 and its components are described below. However, a fixing mechanism of this type can also be used in other embodiments described herein.

[0163] The base module 22, in particular its housing 24, is inserted into the receiving space 32 of the handling module 28 such that a free space 160 is present between the housing 24 and the base body 22. The free space 160 is formed as a hollow cylinder. Due to the free space 160, the housing 24 of the base module 22 does not rest with its entire outer surface against an inner wall of the base body 30. Fig. 12 shows a schematic representation of the fixation mechanism 24 viewed from a proximal side. Reference is also made in part to Fig. 12 below.

[0164] The fixing mechanism 34 comprises a pre-tensioned and / or pre-tensionable pre-tensioning element 36. In the present embodiment, the pre-tensioning element 36 is attached to a cable base 166. The cable base 166 can be part of the supply cable 88. The pre-tensioning element 36 can be removable from the base module 22 together with the supply cable 88. In other embodiments, the pre-tensioning element 36 can be permanently attached to the base module 22. This is possible both in variants in which the supply cable 88 is also permanently attached to the base module 22, and in variants in which an interface between the base module 22 and the supply cable 88 is detachable. For example, in these cases, the cable base 166 can be replaced by a base element of the base module 22 and / or a projection of the housing 24, which carries the pre-tensioning element 36.

[0165] The prestressing element 36 is designed as a spring element. The prestressing element 36 can have a plurality of spring-loaded arms and / or arm sections. The prestressing element 36 can be radially deformable. In particular, an outer diameter of the prestressing element 36 can be reduced by the application of force. The prestressing element 36 can be designed in the manner of a disc spring, in particular as a multi-slotted disc spring. Alternatively, the spring element 36 can have individual arms. For example, two of these arms can be shown in Fig. 9. Preferably, at least two, at least three, at least four, at least five, or at least six arms are present. The fixing mechanism 34, in particular the handling module 28, comprises a holding element 38, which is designed to releasably fix the housing 24 to the handling module 28 by engaging behind it.In particular, the pretensioning element 36 is designed to releasably fix the housing 24 to the handling module 28 by engaging behind the holding element 38.

[0166] The pre-tensioning element 36 is shown in two different positions in Fig. 11. The position shown further to the right (solid lines) is a position in a locking state. The pre-tensioning element 36 is in a locking position. The position shown just to the left (dashed lines) corresponds to a state of the pre-tensioning element 36 during insertion and / or removal from the receiving space 32. The pre-tensioning element 36 is in a release position.

[0167] To insert the base module 22, the user compresses the pre-tensioning element 36 radially to move it into the release position. Upon insertion of the base module 22 into the receiving space 32, the pre-tensioning element 36 can then pass the holding element 38. The pre-tensioning element 36 then relaxes into its fixed position, engaging behind the holding element 38. The pre-tensioning element 36 exerts a force on a distal contact surface of the holding element 38, thereby pressing the base element 22 into the receiving space 32 and / or holding it in the receiving space 32. If a force acting in the proximal direction is exerted on the base module 22 in the inserted and fixed state, the pre-tensioning element 36 counteracts this force and holds the base module 22 in the handling module 28.

[0168] In addition, the handling module 28 and the base module 22 jointly form an alignment aid 56, which defines a preferred position and / or a preferred orientation of the housing 24 relative to the handling module 28. In particular, the alignment aid 56 comprises two inclined sections 162, 163 that extend along the circumference of the handling module 28 and the base module 22, in particular of the housing 24, and are configured to interact with one another, in particular through mechanical contact, such that the base module 22 assumes an axial preferred position in a handleable state. Furthermore, the alignment aid 56 is configured to center the base module 22 such that the longitudinal axis of the base module 22 coincides with the longitudinal axis of the handle 44. The inclined sections 162, 163 are conical in this case. They comprise conical surfaces that lie against one another and which together center the base module 22.

[0169] In addition, the handling module 28 has a sealing element 104, which seals against the base module 22 in the operable state. The sealing element 104 is arranged proximally with respect to the alignment aid 56. The sealing element 104 is, for example, an O-ring. The sealing element 104 is preferably made of a deformable material, in particular an elastic one, such as rubber and / or an elastomer. In the present case, the preloading element 36 presses the base module 22 or its housing 24 against the sealing element 104 when inserted.

[0170] In this case, the base body 30 further comprises a support element 169. The support element 169 supports the housing 24 inside the receiving space 32. In the illustrated case, the support element 169 rests against an outer circumferential surface of the housing 24 at a proximal end of the housing 24 of the base module 22. The support element 169 defines an inner diameter that at least substantially corresponds to an outer diameter of the housing 24. The support element 169 can be annular. Alternatively, multiple support elements can be provided at different circumferential positions.

[0171] In embodiments in which the shaft 70 is designed as an interchangeable shaft, an interface 71 can be provided between the shaft 70 and the housing 24. Such an interface 71 is shown in Fig. 9 as an optional component in dashed lines. Such an interface 71 can be arranged such that, when the base module 22 is inserted, it is located within the receiving space 32. For example, the interface 71 is located proximal to the distal opening 154 of the base body 30. As a result, the interface 71 is protected by the handling module 28.

[0172] Fig. 13 shows a further embodiment of a handling module 428 and a base module 422. The design is similar to that in Figs. 7-9. However, in contrast, a sealing element 404 is arranged distally of the receiving space 432. The sealing element 404 can seal against a shaft 470. In the present case, the sealing element 404 is an O-ring and / or is preferably made of a, in particular elastically, deformable material, for example rubber and / or an elastomer.

[0173] If the shaft 470 is designed as an interchangeable shaft and can be connected to a housing 424 of the base module 422 via an interface 471, the interface can be arranged proximally with respect to the sealing element 404. The interface 471 can thus be protected by the handling module 428. In particular, the interface 471 is tightly enclosed at least from one distal side.

[0174] Fig. 14 shows a schematic representation of another embodiment of a fixing mechanism 624, viewed from a proximal side. The embodiment is similar to the embodiment shown in Fig. 12. Therefore, the following primarily focuses on differences. The fixing mechanism comprises a rotatable fixing element 640, which is rotatably arranged on a proximal end surface of a base module 622. In particular, the rotatable fixing element 640 is rotatably mounted about a longitudinal axis 696 of the base module 622. The longitudinal axis 696 coincides with a longitudinal axis of a handling module 628 when the base module 622 is inserted. In the present embodiment, the fixing element 640 is attached to the cable base 166, similar to Fig. 12. The cable base 166 can be part of the supply cable 88. Further features and alternative embodiments can be similar to those of the supply cable 88 of Fig. 12.In particular, the fixing element 640 can be provided instead of the pre-tensioning element 36. In such a case, the base module 622 can be identical to the base module 22. The fixing element 640 can, in particular, be provided on the cable base 166, and the fixing element 640 can be removable together with the cable base 166. For example, if the base module 22, 622 is to comprise the pre-tensioning element 36 instead of the fixing element 640 in order to make it manageable with the handling module 28, the cable base 166 can be connected to the base module 22, 622.

[0175] In addition, the fixing mechanism comprises two holding elements 638 formed by the handling module 628. The holding elements 638 are arranged on opposite sides of the handling module 628. The holding element 638 is configured to releasably fix a housing 624 of the base module 622 by engaging behind the handling module 628. In particular, the fixing element 640 is movable by rotation between a fixing state and a release state. In Fig. 14, the fixing element 640 is shown in solid lines in the release state. In this state, the base module 622 can be inserted into a receiving space 632 and / or removed from the receiving space 632. The base module 622 can be inserted into the receiving space 632 such that a lateral section of the fixing element 640 engages behind one of the holding elements 638 in the fixing state. The fixing state is represented by dashed lines.In particular, the fixing state and / or the release state can be achieved without tools.

[0176] The user can insert the base module 622 into the receiving space and rotate the fixing element 640 such that the fixing element 640 engages behind at least one of the holding elements 638 to establish the fixing state. Furthermore, the user can rotate the fixing element 640 such that the release state is established and remove the base module 622 from the handling module 628. Furthermore, the user can detach the supply cable 88 together with the cable base 166 and the fixing element 640 from the base module 622. Subsequently, the user can connect the supply cable 88 and the cable base 166 of Fig. 12, including the pretensioning element 36, to the base module 622. This allows the user to make the base module 622 compatible with the handling module 28.

[0177] A further aspect of the fixing mechanism 624 is partially illustrated with reference to Fig. 15. The fixing element 640 comprises a prestressable prestressing element 636. In particular, the fixing element 640 can be the prestressing element 636. The prestressing element 636 is elastically deformable in the axial direction. Fig. 15 shows a schematic side view of the holding element 638. The holding element 638 can partially define a guide track 643 that is angled with respect to a plane perpendicular to the longitudinal axis 696. The guide track 643 is configured to deform the prestressing element 636 in the axial direction upon rotation of the fixing element 640. In addition, the holding element 638 comprises a locking section 645, which is designed as a locking recess, in particular as a groove. In the fixing state, the locking portion 640, or the locking recess, at least partially encloses the prestressing element 636.In this state, the preload element 636 is in an axially advanced position. To move it out of the advanced position, an axial force must be applied to the preload element 636, preferably by the user. The preload element 636 deforms in the axial direction during rotation as it is guided along the guideway. This generates tension and / or potential energy in the preload element 636. If the fixing element 640 and / or the pre-tensioning element 636 is rotated beyond the angled guide track 643, the pre-tensioning element 636 moves, or snaps, into the preferred position in which the tension, or the potential energy, is lower than on the angled guide track 643. To release the fixing mechanism 634, the pre-tensioning element 636 can be deformed in the axial direction, in particular by a user, such that the fixing element 640 can be rotated beyond the locking section 645.In particular, in order to release the fixing mechanism 634, the user can axially deform the biasing element 636, or press on the biasing element 636 from the proximal side, and move the fixing element 640 into the release state.

[0178] It is understood that the illustrated embodiments of the fixing mechanisms can be combined with base modules and / or handling modules as desired. In particular, the fixing mechanisms relate to features that are to be understood as independent of other features of the base modules and / or handling modules.

[0179] Fig. 16 shows a view of a transverse section through another embodiment of a base module 722 and a handling module 728. The base module 722 and the handling module 728 together form an alignment aid 756. The alignment aid 756 comprises four guide slats 758 formed on a radial inner side of the handling module 728. The guide slats 758 protrude into a receiving space 732 of the handling module 728. In addition, the alignment aid 756 comprises four guide grooves 761. The guide grooves 756 are each formed to correspond to one of the guide slats 758. In particular, the guide grooves are formed as recesses in a housing 724 of the base module. By means of the alignment aid 756, a radial preferred position of the base module 722 can be defined by the guide lamellas 758 contacting all guide grooves 761.In particular, the base module 722 is centerable, or the base module 722 is arranged centered in the receiving space 732 when inserted. The guide slats 758 also protrude into the receiving space 732 such that, when the base module 722 is inserted, a free space 760 remains between the housing 724 and the handling module 728. In addition, the guide grooves 761 at least partially accommodate the guide slats 758. In particular, the guide slats 758 can contact side walls, in particular all side walls, of the guide grooves 761. This allows a preferred rotation position to be defined. Furthermore, the guide slats 758 and the guide grooves 761 can improve the guiding properties of the base module 722 when the base module 722 is inserted into the receiving space 732.

[0180] Fig. 17 shows a further embodiment of a handling module 828 in a schematic representation, wherein the base module 622 is shown in an inserted state, or ready-to-use state, in a receiving space 832 of the handling module 828. The handling module 828 is very similar at least to the handling module 28. Differences will therefore be discussed primarily. The present embodiment of the handling module 828 is described below with the aid of Fig. 18 and Fig. 19. Fig. 18 shows a schematic representation of the handling module 828 viewed from a distal side of the handling module 828. Fig. 19 shows a schematic representation of the handling module 828 viewed from a proximal side of the handling module 828.

[0181] The handling module 828 comprises four air inlets 806 on a distal portion 808 of the handling module 828. The air inlets 806 are configured as openings to the receiving space 832 of the handling module 828. The openings are perforations through a distal end surface 817 of the handling module 828. The air inlets 806 can jointly extend over a large portion of the circumference of the distal end surface 817 of the handling module 828. In the illustrated case, the air inlets 806 extend over 90% of the circumference of the distal end surface 817 of the handling module 828. Alternatively, different configurations of the air inlets 806 can be provided. For example, any desired number of air inlets, in particular two, three, five, six, or seven air inlets, can be provided.The air inlets can collectively extend, for example, over 30% to 99%, in particular over 50% to 95%, preferably over 70% to 90%, of the circumference of the distal end surface 817 of the handling module. In particular, the extension of the air inlets can be selected with respect to a power output of the base module. If a greater cooling effect is desired because the base module has a higher power output during operation, a greater extension of the air inlets can be provided. In other embodiments not shown, the air inlets can be arranged at least partially on a radial outer surface of a handling module. Furthermore, the air inlets can be arranged at least partially on a radial outer surface of a handling module and / or at least partially on a distal end surface 817 of the handling module.Referring again to the embodiment shown, the remaining part of the distal end surface 817 comprises four webs 867 which extend particularly radially between the air inlets 806.

[0182] Furthermore, the handling module 828 comprises four air outlets 810 on a proximal section 812 of the handling module 828. The air outlets 810 are interrupted by four support elements 869. The support elements 869 together form a ring, viewed from the proximal side, which tapers in the axial direction. In particular, the support elements 869 together form a cone. The section of the cone with the smallest diameter defines an inner diameter that at least substantially corresponds to an outer diameter of the housing 624. In the inserted state, the support elements 869 are configured to axially guide the base module 622 and to define a radial preferred position. In particular, the support elements 869 are configured to center the base module 622. In the manageable state, a free space 860 exists between the base module 622 and the handling module 828.In other embodiments of a handling module, the proximal side of the base module 722 can be enclosed. In this case, air outlets can be formed, similar to the air inlets, as openings at least partially through a proximal wall and / or at least partially through a radial outer surface of the handling module.

[0183] The air inlets 806 and the air outlets 810 are connected to each other, in particular via the free space 860. The connection between the air inlets 806 and the air outlets 810 can also be defined as an air duct 814. The air duct is hollow-cylindrical in shape. In particular, in a central section of the housing, there is primarily no contact with the handling module 828. A radial inner surface 816 of the air duct is defined by the housing 624.

[0184] In addition, the handling module 828 has a sealing element 804, which seals against the base module 622 in the operable and / or manageable state. The sealing element 104 is, for example, an O-ring. The sealing element 104 is preferably made of a deformable material, in particular an elastic one, for example, rubber and / or an elastomer. Furthermore, the handling module comprises an operating assembly 865, which is designed according to the operating assembly 65. The base module 622 also comprises actuating elements according to the base module 22. It should be noted that the operating assembly 865, in particular, is optional and / or any number of operating elements can be provided.

[0185] The handling module 828 is a one-piece injection-molded part made of a plastic material that has particularly good heat-insulating properties. The user, who guides the handling module 828 by hand, is not adversely affected during use, particularly by the heat-insulating effect of the handling module 828, even though the base module 622, in particular the housing 624, may heat up during operation. In order to keep the base module 622 within a suitable temperature range and / or to dissipate heat from the base module 622 to the environment, the air inlets 806 and the air outlets 810 are provided. Ambient air can enter the free space 860 through the air inlets 806, absorb heat, and exit again through the air outlets 810. The air can thus circulate around the housing 624 and cool it by convection.In particular, a suitable distance must be provided between the housing 624 and the base module 828 in order to achieve air circulation, in particular according to the arrows shown in Fig. 17.

[0186] In the illustration shown, the base module 622 comprises a fixing element 840, which is arranged on a shaft 670 of the base module 622 in close proximity to the housing 624, in particular immovably, and a supply cable 88, which is detachably connected to the base module 88. The supply cable 88 does not comprise a fixing element. With reference to Figs. 12 and 14, it should be noted that the supply cable 88 is compatible with, or connectable to, the base modules shown there. If, for example, air cooling according to Fig. 17, or the handling module 828 for handling the base module, is provided, the supply cable 88 can be connected to the base module without a fixing element, in particular by the user.

[0187] The handling module 828 and the base module 622 together form a fixing mechanism 834, as described below. In the operable state, the fixing element 840 is arranged axially within the handling module 828. Furthermore, the fixing element 840 is arranged distally to the sealing element 804. The fixing element 840 comprises two radial projections 871 that extend from circumferentially opposite sides of the shaft 670. According to Fig. 18, the handling module 828 comprises a holding element 838 and two recesses 866 formed corresponding to the projections 871. The holding element 838 is configured to releasably fix the housing 624 to the handling module 828 by engaging behind it. The recesses 866 are designed such that the projections 871 can be passed through the recesses 866, in particular during the introduction of the base module 622 into the receiving space 832. As soon as the projections 871 are distal to an axial outer surface, orend face of the holding element 838, or completely passed through the recesses 866, the base module 622 together with the shaft 670 and the projections 871 is rotatable in order to bring the base module 622 into a fixing position.

[0188] In order to guide the projections 871 completely through the recesses 866, the sealing element 804 is axially compressed. In particular, the housing 624 presses on the sealing element 804, particularly in the inserted state and / or during insertion. As a result, the sealing element 804 exerts an axial force on the housing 624 counter to an insertion direction of the base module 622. In particular, even after the base module 622 has been rotated, the sealing element 804 presses on the housing 624. As a result, the fixing element 840 presses on the holding element 838 from the distal side. In particular, the handling module can be clamped by the sealing element 804 and the projections 871 and / or is clamped in the operable state. In order to release the handling module, the housing can be pressed axially against the sealing element 804 and, as a result, the base module 622 can be rotated so that the projections 871 can be guided through the recesses 866.

[0189] To insert the base module 622 into the receiving space 832 and / or fix the base module 622 to the handling module 828, in particular to establish the operable state, the user extends the shaft 670 from the receiving space 832 on the distal side of the handling module 828. Furthermore, the user guides the projections 871 through the recesses 866. In doing so, the user presses the housing 624 against the sealing element 804. As soon as the projections 871 are arranged distal to the holding element 838, the user rotates the base module 622 to establish the operable state and consequently no longer exerts any force on the base module 622 and / or the housing 624. In the operable state, the sealing element 804 presses the housing 624 in the axial direction such that the handling module 828 is clamped between the projections 871 and the housing 624.To release, the user presses the housing 624 against the sealing element 804 and rotates the base module 622 such that the projections 871 can be guided through the recesses 866 and guides the projections 871 through the recesses 866.

[0190] Fig. 20 shows a further embodiment of a handling module 928 in a schematic representation, wherein the base module 622 is shown in an inserted state, or ready-to-use state, in a receiving space 932 of the handling module 928. The handling module 928 is very similar at least to the handling module 828. Therefore, differences will be discussed primarily. With regard to a fixing mechanism 934, reference is made in particular to the fixing mechanism 834, which are designed in the same way. The present embodiment of the handling module 928 is described below with the aid of Fig. 21 and Fig. 22. Fig. 21 shows a schematic representation of the handling module 928 viewed from a distal side of the handling module 928. Fig. 22 shows a schematic representation of the handling module 928 as viewed from a proximal side of the handling module 928.

[0191] The primary difference between handling module 928 and handling module 828 is that handling module 928 has no openings through a distal end surface 917. In particular, it should be noted that handling module 928, like handling module 828, can be used with or is compatible with many base modules. Handling module 928 is shown together with base module 622 purely as an example. Furthermore, handling module 928 has similar advantages with regard to thermal insulation as handling module 828. In particular, handling module 928 is made largely of a plastic and / or can be at least substantially formed in one piece. In particular, a base body 930 is formed in one piece.

[0192] A coolant communication interface 921 is provided for cooling the base module 622. In particular, the handling module 928 comprises the coolant communication interface 921, via which a cooling fluid, in particular cooling air, can be introduced into the receiving space 932. A hose 971 can be releasably attached to the coolant communication interface 921. The hose 971 can be releasably attached to the coolant communication interface 921, for example, by means of a rotary coupling, in particular comprising a union nut, a claw coupling, or a plug-in coupling. Furthermore, the hose 971 can be coupled, for example, to the supply unit 12 and / or an air supply unit, which is configured to provide cooling air. In particular, the cooling air can be provided with a controllable and / or adjustable pressure and / or flow.

[0193] The cooling air can be directed and / or forced into a channel 969 via the hose 971. The channel 969 extends within a lamella 929, which extends from the proximal end of the handling module 982 to a distal portion 908 of the handling module 928. In particular, the lamella 929 extends over 85% of the length of the housing 624. In other embodiments, the lamella can extend over, for example, 90%, 95%, 80%, and / or any other distance relative to the housing 624. The lamella 929 is formed by the handling module 928 and protrudes from a radial inner surface of the handling module 928 into the receiving space 932. In particular, at least one radially inner point of the lamella 929 contacts the base module 622 in the operable state. The slat may have similar properties, in particular guiding properties and / or centering properties, as the support elements 869, 169 and / or the guide slat 758.At the distal portion 908, the channel 969 opens into the receiving space 932 and defines an air inlet 906.

[0194] In addition, the handling module 928, similar to the handling module 828, has a sealing element 904 that seals against the base module 622 in the operable state. Furthermore, the sealing element 904 has the same properties with respect to the fixing mechanism 934 as with respect to the fixing mechanism 834. The receiving space 934 is sealed from the environment at the distal portion 908. Air is introduced into the receiving space 932 through the air inlet 906 via the coolant communication interface 921. The air flows, as shown by the arrows in Fig. 20, toward the proximal portion 912. In particular, the air flows along a hollow cylindrical air channel 914, which is defined by a free space 960, similar to the free space 860. A radially inner surface 916 of the air channel 914 is defined by the housing 624. A radially outer surface of the air channel 914 is defined by a radially inner surface of the handling module 928.At the proximal section 912, the handling module 928 comprises three air outlets 910. The air outlets 910 are connected, as already described, to the air inlet 906. Air flowing into the receiving space 932, in particular the air duct 914, through the air inlet 906 flows out of the receiving space 932, in particular the air duct 914, through the air outlets 910. The air can absorb and / or dissipate heat from the base module 622 as described in connection with the handling module 828. In contrast, the amount of air introduced into the receiving space 932 through the air inlet 906 can be controlled and / or regulated as needed and / or in a specific application. If, for example, a greater cooling effect is required, a larger amount of air can be introduced and / or air at a lower temperature can be introduced.

[0195] The air outlets 910 extend along the circumference of the handling module 928. This is particularly clearly visible in Fig. 22. The air outlets 910 are interrupted circumferentially by the lamella 929, which encompasses the channel 969, and two further lamellae 929. For clarity, the further lamellae 929 are provided with the same reference numerals. Viewed from the proximal side, the lamellae 929 together form a ring that tapers in the axial direction. In particular, the lamellae 929 together form a cone. A radially innermost section of the cone defines an inner diameter that at least substantially corresponds to an outer diameter of the housing 624. The lamella 929, which encompasses the channel 969, does not taper, unlike the other two lamellae 929. In the operable state, the slats 929 are configured to guide the base module 622 axially and to define a radial preferred position.In particular, the fins 929 are configured to center the base module 622. The fins 929 can have a similar function to support elements 169, 869 with regard to the insertion of a base module and / or spatial alignment of a base module. The additional fins 929 extend over the same distance to the same axial position as the fin 929 that encompasses the channel 969. At the distal section 908, the fins 929, in particular, do not extend to the distal end surface 917, or a wall defining the distal end surface 917. The air can flow around the fins 929 at the distal section 908.

[0196] Another embodiment of a handling module 1028 is shown in Fig. 23 and

[0197] Fig. 24. Fig. 23 shows a schematic representation of a proximal section 1012 of a handling module 1028, wherein the base module 622 is shown in an inserted state, or in an operational state, in a receiving space 1032 of the handling module 1028. The handling module 1028 is very similar at least to the handling module 928. Therefore, differences will be discussed primarily. Fig. 24 shows a schematic representation of the handling module 1028 viewed from a proximal side of the handling module 1028.

[0198] In contrast to the handling module 928, the handling module 1028 is configured to enable liquid cooling of the base module 622. The handling module 1028 comprises a support element 1069, designed as a ring element, on the proximal section 1012. The support element 1069 is formed integrally with the handling module and / or extends from a radial inner surface of the handling module 1028 into the receiving space 1032. The handling module 1028, in particular the support element 1004, also has a sealing element 1004, designed as an O-ring. The sealing element 1004 is partially received by a sealing element circumferential groove on a radial inner surface of the support element 1069 and / or seals against the base module 622, in particular the housing 624, in the operable state. The support element 1069 also tapers conically.The support element 1069 can guide, align, center and / or support the base module 622 according to the other support elements and / or the like.

[0199] The distal portion of the handling module 1028 is configured similarly to the distal portion 908 of the handling module 928. In particular, the receiving space 1032 at the distal portion is sealed from the environment. Generally, in the handleable state, the receiving space 1032 is sealed from the environment.

[0200] In addition, the handling module 1028 comprises a coolant communication interface 1021, via which a cooling fluid can be introduced into the receiving space 1032. The handling module 1028, in particular the coolant communication interface 1021, comprises two hoses 1071 that are guided through the support element 1069. In particular, the hoses 1071 are permanently connected to the handling module 1028. The handling module 1028 is also a single-use product and is disposed of and / or recycled together with the hoses 1071 after use. The cooling fluid, for example water and / or any other suitable liquid coolant, can be introduced into the receiving space 1032 via one of the hoses according to the arrows shown in Figs. 23 and 24. The tube 1071, by means of which the cooling fluid is introduced, extends to the distal section not shown.At the distal portion, the cooling fluid is introduced into the receiving space 1032. The hoses 1071 can be coupled, in particular, to the supply unit 12, a pump, and / or a coolant supply unit. These can be configured to introduce the cooling fluid, similar to the cooling air according to the handling module 928, into the receiving space 1032 at a controllable and / or adjustable volume flow and / or pressure and / or at a controllable and / or adjustable temperature.

[0201] The handling module 1028 also comprises at least two fins 1029, in the present case four fins 1029, of which only one is visible in the figures. The fins are designed similarly to the fins 929 and, in particular, contact the housing 624 along their longitudinal direction. The fin 1029, which is shown in Fig. 23, extends to a distal end surface, or rather its receiving space-side wall, in the distal section of the handling module 1028 (not shown). The cooling fluid, which is introduced at the distal section, is guided through a fluid channel to the proximal section. A radially inner surface of the fluid channel is defined by the housing 624, and a radially outer surface is defined by a radially inner surface of the handling module. Side surfaces of the fluid channel are defined, in particular, by the fins 1029.

[0202] The illustrated lamella 1029 does not extend to the support element 1069 at the proximal portion 1012. In particular, a proximal end 1073 of the lamella 1029 is spaced from the support element 1069. In particular, the lamella 1029, in particular the proximal end 1073 of the lamella 1029, is spaced from the support element 1069 such that the cooling fluid can pass through the lamella 1029 circumferentially. In contrast, a circumferentially next lamella 1029 extends from the support element 1069 to a distal end, wherein the distal end is spaced from the distal end surface such that the cooling fluid can pass through the lamella 1029 circumferentially at the distal portion. Additional fins 1029 may extend in the same pattern such that they are alternately spaced from the distal end surface and the support element. In summary, the cooling fluid can be directed labyrinthinely along the housing.The cooling fluid is led to the hose 1071 of the coolant communication interface 1021 and out of the receiving space 1032 via the hose 1071.

[0203] Advantageously, a liquid cooling fluid can achieve better cooling performance compared to air cooling. Furthermore, a smaller diameter of the handling module 1028 can be provided.

[0204] Fig. 25 shows a further aspect of the endoscope 320, comprising the handling module 328 and the base module 322, in a schematic representation. Fig. 26 shows a schematic representation of the handling module 328 in a sectional view of the proximal side of the handling module 328. With reference to these two figures, an exemplary embodiment of a base module cooling system is described below. It should be noted that this form of base module cooling can be combined with other embodiments of handling modules, including those shown herein. The endoscope 320 comprises a cooling module 122, which is provided for cooling the base module 322. The cooling module 122 can be arranged within the handle 344. In particular, the cooling module 122 comprises a latent heat accumulator 126. The latent heat accumulator 126 is arranged in a housing of the cooling module 122. The housing has good heat-conducting properties.The base body 330 of the handling module 328 defines a cooling module receiving space 124 into which the cooling module 122 can be inserted. Furthermore, a longitudinal axis of the handle 344 of the endoscope 320 is inclined with respect to a longitudinal axis of the receiving space 334. In particular, the handle 344 is a pistol grip.

[0205] In particular, the user can insert the cooling module into the cooling module receiving space 124 and / or create a handleable state. When the cooling module 122 is inserted in the handleable state, the cooling module 122 and the base module 322 are at least thermally in contact. This can mean that the cooling module 122 is in thermal contact with the base module 322 indirectly via, for example, heat conductors, in particular copper elements, or directly. In the illustrated form, the cooling module 122 can be inserted from a lateral side into the handle 344, in particular into the cooling module receiving space 124. Furthermore, the cooling module receiving space 124 opens into the receiving space 332 of the handling module 328. In the handleable state, the cooling module 122 can be brought into physical and thermal contact with the base module 322 by inserting it into the cooling module receiving space 124.Furthermore, the base module 322 and / or the cooling module 122 has a heat-conducting, deformable element 128, which rests against the cooling module 122 or the base module 322 in the handleable state and in the inserted state. The heat-conducting, deformable element has similar properties to the elastic heat-conducting element 352 and / or can be formed, for example, from a heat-conducting elastomer. In the present case, the heat-conducting, deformable element 128 is arranged on the cooling module 122. Waste heat is dissipated via the heat-conducting element 128 and / or conducted from the base module 322 to the cooling module 122. In addition, the heat-conducting element 128 can clamp the base module 322, whereby it is securely held in the receiving space 332. In particular, in the manageable state and in the inserted state of the cooling module 122, the cooling module 122 applies a force to the base module 322.A fastening mechanism 321 is provided to maintain the force application. The fastening mechanism 321 comprises two push buttons 323, two locking lugs 325, and a locking hole 327. The push buttons 323 are arranged laterally on the base body 344. Furthermore, the push buttons are mechanically connected to the locking lugs via a lever arrangement. The locking lugs 325 protrude partially into the cooling module receiving space 124. By operating the push buttons 323, the locking lugs 325 can be moved at least substantially out of the cooling module receiving space 124. Furthermore, the locking lugs 325 can be moved out of the cooling module receiving space 124 by inserting the cooling module 122 into the cooling module receiving space 124. When the cooling module 122 is inserted, the locking lugs 325 engage in the locking hole 327. In particular, the locking lugs 325 hold the cooling module 122 by engaging behind it in the cooling module receiving space 124.Furthermore, the user can apply a force to the heat-conducting, deformable element 128 during the insertion of the cooling module 122. The locking lugs 325 are configured to hold the cooling module 122 in the cooling module receiving space 124 in such a way that the base module 322, in particular the heat-conducting, elastic element 128, is subjected to a force. To remove the cooling module 122, the user can operate the push buttons 323. In this case, the force applied to the base module 322 causes the cooling module 122 to move in the opposite direction to the insertion direction of the cooling module 122.

[0206] Fig. 27, Fig. 28 and Fig. 29 show a schematic detailed representation of the operating module 65 and the associated operating elements 64. Fig. 27 shows a schematic side view of a section of the base module 22, a section of the main body 30 of the handling module 28 and the operating module 65. The operating module 65 has already been described in principle in connection with Fig. 4. It can be seen in Fig. 27 that the operating module 65 can be manufactured separately from the main body 30. The operating module 65 comprises a housing 69 and three operating elements 64. Two of the operating elements 64 are designed as push buttons 67. The third operating element 64 is designed as a rotary knob 70.

[0207] The actuating elements 64, in particular the push buttons 67, each comprise a magnet 66, which is in particular a rare earth magnet, for example comprising neodymium, dysprosium, and / or samarium. In the embodiment shown, the magnet 66 of the push buttons 67 comprises two poles arranged consecutively in the radial direction. Furthermore, the push buttons 67 are guided such that they are movable in the radial direction. By actuating, in particular pressing, the push buttons 67, the respective magnet 64 can be moved toward an associated actuating element 62 of the base module 22.

[0208] Furthermore, the rotary knob 70 comprises a magnet 66, which is in particular a rare earth magnet, for example comprising neodymium, dysprosium, and / or samarium. This magnet 66 comprises two poles arranged consecutively in the axial direction. By actuating, in particular pressing, the push buttons 67, the respective magnet 64 can be moved toward an associated actuating element 62 of the base module 22. By actuating, in particular rotating, the rotary knob 70, the magnet 64 can be moved relative to an associated actuating element 62 of the base module 22, in particular rotated, or moved into a different rotational position.

[0209] In principle, instead of at least one magnet 66, a component made of a ferro-, ferri- and / or paramagnetic and / or other electrically conductive material can be provided.

[0210] At least one of the actuating elements 62 can comprise a Hall sensor 68. In the present example, all actuating elements 62 each comprise a Hall sensor 68. The function of the actuating elements 62 is explained using an example of an actuating element. By means of the actuating element 62 comprising the Hall sensor 68, a particularly local magnetic flux density of the magnet 66 of a push button 67 can be measured. By knowing the magnetic flux density, a relative radial position of the push button 67 and / or the magnet 66 associated with the push button 67 to the actuating element 62 can be deduced. The push button 67, together with the actuating element 62, can form a switch that can be switched between two positions. The switch can, in particular, be a proximity switch, for example a magnetic proximity switch, a capacitive proximity switch, an optical proximity switch, and / or an inductive proximity switch.Furthermore, the switch can be switchable between more than two positions, for example, three, four, or five positions. The positions are defined by a radial relative position of the push button 67, in particular the corresponding magnet 66, to the actuating element 62, in particular the corresponding Hall sensor 68. The push button 67 can comprise a reset element configured to return the push button 67 to an initial position after actuation. The reset element can be an elastic element, in particular a spring element.

[0211] Furthermore, a rotational position of the rotary knob 70 and / or the magnet 66 associated with the rotary knob relative to the actuating element 62 can be deduced. The actuating element 62 can comprise several, in particular two, three, or four, Hall elements 62, in particular for measuring the rotational position. The actuating element 62 can be configured to measure the rotational position with a resolution of, for example, 0.1° to 20°, in particular 0.5° to 10°, and preferably 1.0° to 5°. The associated actuating element 62 is actuated according to the rotational position.

[0212] Fig. 28 shows a schematic view of the operating assembly 65 from the proximal side. In particular, one can see the rotary knob 70 comprising the magnet 66 and the actuating element 62 assigned to the rotary knob 70, which comprises at least one Hall sensor 68. Furthermore, a further aspect can be seen that has already been described in connection with Fig. 3. In Fig. 28, in addition to the actuating element 62 assigned to the push button 70, one can see a further actuating element 62 that is structurally identical and / or functionally identical to the other actuating element 62. The further actuating element 62 is located opposite the other actuating element 62. By rotating the base module 22, which can be advantageous in particular with regard to a viewing direction of the endoscope 20, the further actuating element 62 can be arranged with respect to the operating element 64, in particular the rotary knob 70, in such a way that it can interact with the latter.

[0213] Fig. 29 shows a schematic top view of the operating assembly 65. The three actuating elements 64 can be seen, two of which are designed as push buttons 67 and one as a rotary knob 70. Also visible is the housing 69 of the operating assembly 65, into which the actuating elements 64 are at least partially embedded. In embodiments not shown, the operating assembly comprises one, two, four, five, six, and / or seven actuating elements 64.

[0214] 30 and 31 show a further aspect of the supply cable 88; the respective embodiments shown differ only slightly. Referring to Fig. 30, it can be seen that the supply cable 88 comprises a plug 91 of the connector 90 already described in connection with Fig. 3. The plug 91 extends along the longitudinal axis 96 of the base module (not shown). The supply cable 88 is rotatable when connected to the base module. Furthermore, it can be seen that a cable outlet direction 94 of the supply cable 88 from the base module is inclined with respect to the longitudinal axis 96 of the base module. In the case shown, the cable outlet direction 94 is inclined by 90° with respect to the longitudinal axis 96. The inclination of the cable outlet direction 94 is defined in particular by a transition section 92 of the supply cable 88 which adjoins the plug 91.In the present case, the transition section 92 is made of hard plastic. Alternatively or additionally, the transition section 92 can be made of rubber, a plastic, and / or a metal. In particular, the supply cable 88 is reinforced in one area of ​​the transition section 92.

[0215] Fig. 31 shows a section of a substantially identical supply cable 88. The difference is that the cable outlet direction 94 is inclined by 45° relative to the longitudinal axis 96.

[0216] Fig. 32 shows a schematic representation of a medical robot 132. The robot 132 comprises a robot arm 133, a robot control unit 129, and a holder 130. The holder 130 is arranged at a proximal end of the robot arm 133. The handling module 28 is configured to be attached to the holder 130 of the medical robot 132 and to make the base module 22 manageable for the robot 132. The holder 130 is formed together with the handling module 28. In other embodiments, the holder is formed separately from the handling module. By means of the robot arm 133, the base module 22 can be moved in all spatial directions and / or pivoted about at least one, in particular adjustable, spatial point.

[0217] Fig. 33 shows a schematic flow diagram of a method for providing the endoscope 20. For a detailed description, reference is made to the explanations at least in connection with Figures 1 to 4. The method comprises at least a step 1100 of providing the base module 22, a step 1102 of providing the handling module 28, and a step 1104 of inserting the base module 22 into the handling module 28 by the user. It is understood that the described method is transferable to at least all embodiments of base modules and handling modules according to the invention and / or shown.

[0218] In other words, the following aspects are described here, among others.

[0219] A base module can comprise an endoscope shaft and a proximal end section with an interface to the CCU (Computer Control Unit). The base module can also include sensors for detecting key magnets. Functions for generating an image (camera and illumination) can be located within a hermetically sealed housing, ensuring autoclavability. A special feature can be the installation of magnetic sensors on two opposite areas of the housing. This is advantageous for angled-view endoscopes, as the user can determine whether the viewing direction is upwards or downwards relative to the keys by inserting them into the handle at 180° offsets.

[0220] A cable interface is preferably designed coaxially. This allows a cable outlet that is not 0° to be rotated in the direction desired for the respective application. Likewise, the user can replace the cable in the event of a defect, as no rotation angle on the axis needs to be observed during the plugging process. Thanks to the serializer in the base module and an additional filter for power transmission, a simple coaxial cable is sufficient to connect to the CCU. These simple cables are so inexpensive to purchase that single-use could also be considered. If autoclavable materials are used for the cable, the cable can remain plugged in permanently. This solution is advantageous because the user does not have to make any further electrical connections besides the always-required connection to the CCU.

[0221] In handheld applications, a handle part takes over the tasks of guiding the endoscope, providing thermal insulation and controlling the electrical functions (buttons, rotary dial).

[0222] In some variants, the base module with the cable plugged in can be inserted into the handle from proximal to distal and locked.

[0223] If a base module is positioned centrally within the handling module, it can dissipate its power losses directly into the air flowing through it. By omitting any electronics in the handling module, it can be designed as a disposable plastic part (the cost of any magnets is negligible). The poor thermal conductivity of the plastic insulates the user from the high temperatures of the base module surface. This has a positive effect on heat dissipation, as convection improves the greater the temperature difference between the incoming cooling air and the base module surface. If the LEDs are installed proximally, the better heat dissipation allows them to be operated at higher power, which provides a reserve of lighting for critical situations such as heavy bleeding, or allows the surgical site to be better illuminated overall.

[0224] If a cooling fluid is introduced into the space between the base module and the handle via a supply hose, the coolant exits warmed at the proximal end. Since the coolant has no contact with the patient, ambient air can be used for cooling. The overall diameter of the handle can be reduced, which provides a handling advantage.

[0225] If liquid cooling is used, a return line and a seal in the proximal area can be provided. At the same flow rate, a significantly greater amount of heat can be removed than with air due to the high heat capacity of water or other cooling liquids. This variant is therefore suitable for high-performance LEDs installed proximally in the base module, which make a stationary light source obsolete for most applications.

[0226] When using media cooling, the single-use version of the handling module is preferable, as the necessary supply and return hoses can be integrated into the handle and no problems arise during reprocessing.

[0227] For positioning within the handling module, there can be centering bevels in the front part which, together with the rear guide and the spring force of the locking mechanism, ensure a precise and secure position. Different designs can be identical or similar to one another, particularly except for one type of seal. The rear part can contain a snap spring which automatically locks when inserted. To unlock and pull out the base module, the spring must be manually pushed into an unlocking position. A similar situation applies with a locking option where the tension of the spring can be generated by screwing it in along a slightly inclined path. The end position can be slightly recessed compared to the bevel so that the spring clicks into place and can only be unlocked again by pressing it together and turning it.The options shown represent basic solutions, which are primarily intended to demonstrate the ease of assembly during surgical preparation.

[0228] The buttons on pistol grip variants are operated via a simple mechanism that moves the magnets to the correct position on the base module, thus triggering the desired function. With a pistol grip, the cable exits downwards, preferably at the knob. For this purpose, the base module can be equipped with a cable variant with an angled angle to the plug-in axis.

[0229] Another handle variant, as explained, is a pen-like handle. The endoscope is then constructed like a so-called penscope. The pushed-on handle section is extended forwards. However, the diameter of the extended section is only slightly larger than the shaft diameter, so that the instrument can be held and rotated between the thumb and index finger like a pencil. The larger diameter rests on the metacarpal in the area between the thumb and index finger. This variant is particularly preferred in neurosurgery. In some variants, the power loss generated in the base module can be transferred to a cooling module filled with phase-change material. The phase transition allows a large amount of energy to be stored in the cooling module despite its small volume.This makes it possible, for example, to eliminate the need for water cooling with the additional hoses, water reservoir, and pump required. The system can be operated indefinitely because the cooling module can be easily replaced. For improved heat transfer, the cooling module can be equipped with an elastic yet highly thermally conductive material at the contact surface with the base module, thus ensuring a large or maximized heat exchange surface.

[0230] Particularly in variants with a pistol grip, it can be designed to clamp the base module after the clip closure is closed. The pistol grip can then absorb the lost heat via an elastic, heat-conducting material and distribute it over a larger surface area. Due to the elastic material, the base module can no longer be inserted in some versions, but is conveniently clamped in place. The principle is not limited to a pistol grip. Depending on the power to be dissipated, simply increasing the diameter of a round handle may be sufficient to keep temperatures within the user's comfort zone.

[0231] A variety of user input elements are possible based on contactless magnetic sensors. In addition to touch functions, analog input can also be provided via a rotation angle sensor. This type of input is advantageous for controlling image focus or a continuous electronic zoom. A rotation angle sensor, in particular, is very sensitive to the correct distance on the Z-axis. In the area of ​​this sensor, the round base housing can have a flattened section so that the magnet can be placed as close as possible to the sensor. Likewise, the material of the base module housing can be diamagnetic, which is the case with steel, for example.

[0232] If the selectability of the button position relative to the oblique viewing direction is desired and the Hall sensor is installed mirrored, the option of making inputs on the top and bottom can be used to place sparsely used functions or functions that should not be accidentally adjusted during operation (e.g. focusing with a rotary wheel) on the more difficult-to-access side.

[0233] In principle, the insertion direction of the base module can also be reversed, i.e., it is inserted from distal to proximal. This is advantageous if the receiving handling module is equipped with electronics and is not autoclaved, but rather covered with a drape for each application.
