Description

[0001] The present invention relates to the disassembly and disposal of a medical instrument, in particular a disposable medical instrument. The present invention relates specifically to the medical instrument itself, a supply unit for it, a medical system comprising a medical instrument and a supply unit, a disposal device, and a method for disassembling and disposing of a medical instrument.

[0002] German patent DE 30 21 263 A1 describes an adhesive bonding process for manufacturing a component that can be assembled from individual parts. An electrically conductive fiber is embedded in the adhesive in the bond line. The application of resistance heat can destroy the adhesive bond.

[0003] German patent DE 39 08 842 A1 describes a device with a thermally detachable connection between two parts with different expansion properties. An inner part made of a thermally conductive material is arranged around a support element made of a material with a low coefficient of thermal expansion. An outer part made of a thermally conductive material with a comparatively much higher coefficient of expansion has a recess into which the inner part can be inserted at an assembly temperature, forming an assembly gap. The outer part has a heating device in the area of ​​the assembly gap.

[0004] EP 0 521 825 A2 describes a releasable adhesive bond. A heatable separating element is arranged on or within a bead of adhesive. The heatable separating element can be applied by co-extrusion together with the adhesive bead or applied to one of the parts to be joined before the adhesive bead is applied, for example, by spraying, brushing, or printing a layer. The heatable separating element is, in particular, electrically conductive or heatable by means of high-frequency, microwave, or infrared radiation.

[0005] German patent DE 198 22 044 A1 describes a releasable adhesive bond for joining a window pane to a frame. An exothermic reaction of a substance added to the adhesive bond irreversibly reduces its mechanical strength, as high temperatures lead to rapid thermal decomposition of the bond.

[0006] German patent application DE 199 51 599 A1 describes a method for the adhesive separation of bonded joints. A primer layer between a substrate layer and an adhesive layer contains nanoscale particles in a binder matrix. In an alternating electric, magnetic, or electromagnetic field, the nanoscale particles heat up. The energy input into the primer layer results in a significant local temperature increase, which enables the adhesive joint to separate.

[0007] US Patent 2013 / 0180973 A1 (US 2013 / 0 180 973 A1) describes a printed circuit board with integrated heating for a printed circuit. Heating traces within the board serve as resistive heating elements. A horizontal heating layer and a vertical heating layer are provided.

[0008] US Patent 2016 / 0091932 A1 (US 2016 / 0091932A1) describes connection arrangements for a computer device.

[0011] WO 2021 / 213815 A1 (WO 2021 / 213 815 A1) describes a heat-separable two-layer adhesive system. One of the two adhesive layers contains conductive particles. When a low voltage is applied, the conductive particles are heated to loosen the interface between the first and second adhesive layers, making the adhesive system easily separable.

[0012] US Patent 2022 / 0127496 A1 (US 2022 / 0127496A1) describes a photonic debonding process for wafer-level packaging applications. A stack comprises a component substrate with a first and a second surface, a bonding layer on the first surface, a transparent substrate with a front and a back surface, and a light-absorbing layer with a first side and a second side. The first side of the light-absorbing layer is located on the front surface of the transparent substrate, and the second side of the light-absorbing layer is located on the bonding layer. Exposure of the bonding layer to pulsed broadband light enables the separation of the component substrate from the transparent substrate.

[0013] US Patent 2024 / 0006048 A1 addresses the recovery of surgical instrument parts. A surgical instrument should include components that can be easily opened to provide access to the internal components, allowing them to be separated into separate waste streams with minimal tooling. A robotic surgical system includes tools for separating the parts of a surgical instrument.

[0014] In WO 2025 / 012798 A1, a surgical system with an interactive disposal guide is described. Instructions can be provided at each step of the separation process to guide the user through the details of the separation, based on the components to be separated and the relevant waste disposal procedures.

[0015] German patent application DE 10 2009 037 315 ​​A1 describes a device for receiving items to be disposed of in an operating room. The device comprises an identification unit with multiple read heads for reading information from data carriers attached to the items to be disposed of, a sorting device, and a container. The read heads can be configured as barcode readers or RFID readers.

[0016] CN 115870937 A describes a device for the maintenance and disassembly of endoscopes.

[0017] CN 217699843 U describes an integrated workbench for bonding after a repair and for disassembling a flexible medical endoscope.

[0018] CN 212170257 U relates to the maintenance of medical equipment. It describes an auxiliary heating device for disassembling a rigid-shaft endoscope.

[0019] US Patent 2009 / 0267765 A1 describes a medical device monitoring system that uses RFID technology.

[0022] US 6 387 858 B1 describes the treatment of surgical instruments after a surgical procedure with an antimicrobial gel that prevents drying and crusting of blood.

[0023] In DE 42 05 697 C1 a device for preparing used medical disposable instruments for disposal and sterilizing them by melting is described.

[0024] One object of the present invention is to provide an improved medical instrument, an improved supply unit for a medical instrument, an improved disposal device and an improved method for dismantling and disposing of a medical instrument.

[0025] This task is solved by the subject matter of the independent claims.

[0026] Further embodiments are defined in the dependent claims.

[0027] A medical instrument comprises a first component, a second component, a connection between the first component and the second component, and a release device for weakening the mechanical connection between the first component and the second component, wherein the connection weakened by the release device resists a predetermined separating force for a predetermined duration.

[0028] Medical instruments are increasingly being designed and manufactured for single use. This eliminates the need for complex cleaning and sterilization processes, which place particular demands on disassembly and—in the case of sterilization by autoclaving—on heat resistance and leak tightness. However, the disposal of single-use instruments objectively represents a waste of resources, which can also be subjectively perceived as burdensome by the users. Disassembly of the used instrument allows for the recycling of materials and / or the reuse of components, thus significantly reducing resource consumption.

[0029] The medical instrument is designed and intended for use in minimally invasive procedures. For this purpose, the instrument may have a long and thin, rigid or partially or fully flexible shaft that connects a handling device at a proximal end of the instrument to a camera or other observation device, or a tool or other working device, at a distal end. The handling device is designed and intended for placement outside a patient's body, and the distal end of the instrument is designed and intended for placement within a body cavity. The medical instrument could be, for example, an endoscope or a tool for grasping, squeezing, cutting, punching, or coagulating.

[0030] The first and second components are made of different materials. However, both components can also be made of partially or completely the same materials. Both components can be manufactured separately and then joined, with the joining point being the connection point. If both components are made of the same material, they can be manufactured simultaneously and originally as a single piece. The connection point is then, for example, an area with a reduced cross-section.

[0031] The first and second components are specifically designed and intended for different further treatments and processes. These further processes include, in particular, reprocessing for reuse, further dismantling, material recycling, thermal recovery, or disposal in a landfill.

[0032] The connection point can be a material-bonded connection, such as an adhesive bond, a soldered joint, or a welded joint. Alternatively or additionally, the connection point can be a force-fit connection, where, for example, one of the two components is shrunk onto the other or both components are connected by a clamp. Alternatively or additionally, the connection point can be a form-fit connection, such as a screw connection or a snap-fit ​​connection.

[0033] The joint can be a surface, for example, the interface between two components joined by friction (also known as force-fit). The joint can also be a two-dimensional, but thin-walled and more or less sharply defined volume, for example, the volume of an adhesive layer, a solder layer, or—somewhat less sharply defined—a weld seam between the components. The surface or thin-walled volume can be flat, curved, or bent, and simple or multiply connected.

[0034] The surface or thin-walled volume can, for example, have the shape of a section of the lateral surface of a cylinder with a circular or other cross-section, or a section of a lateral surface of a cone with a circular, polygonal, or other base.

[0035] The surface or thin-walled volume can be composed of several planes or curved sub-surfaces.

[0036] The connection point can also be a three-dimensionally extended and more or less sharply defined volume, for example an area of ​​reduced wall thickness or reduced cross-section between the two components.

[0037] The mechanical connection is weakened or partially disconnected when the release device has partially disconnected the mechanical connection as intended, for example, by receiving a predetermined power supply during a predetermined release time. The predetermined release time and power supply are provided, in particular, by a supply unit as described herein or by a disposal device as described herein. Due to the compatibility specified by the manufacturer through operating instructions or similar documents, and also, for example, by the geometry of connectors, the predetermined power supply and release time are clearly defined. Furthermore, medical device law, which regulates the use and disposal of medical devices, contributes to this.

[0038] The release mechanism is specifically designed to receive electrical power. Alternatively, the release mechanism can be designed, for example, to receive optical power. The medical instrument and the release mechanism are designed to receive power from an external power source, such as via a cable. When power is supplied, the release mechanism weakens the mechanical connection between the components.

[0039] The release device is specifically designed to heat the connection point.

[0040] The connection point and the release mechanism can be designed such that the release mechanism weakens the connection point and the mechanical connection between the components only while power is being applied. In this case, the mechanical connection is weakened to its maximum extent, particularly at the end of the release period, thus offering minimal resistance to separation. For example, the release mechanism softens an adhesive or solder, or areas of the components that create a positive-locking connection, or reduces static friction and thus a frictional connection between the components. If the components are not separated during or immediately after the power is applied, the connection point returns to its original state after the power supply ceases, and the mechanical connection regains—at least approximately—its original strength.

[0041] If the joint includes an adhesive or other material in a gap between the components, the release device can be designed to soften the material in the gap. Even in its softened state, the material in the gap maintains a residual adhesion between the components due to its viscosity or surface tension. To achieve this, the release device heats the material in the gap, particularly with a predetermined power output, up to a predetermined temperature range. Within this range, the material softens but does not yet vaporize, burn, or completely flow out of the gap. Instead, it remains in the gap and exerts a predetermined residual force to prevent the components from separating. Especially when this residual force is based on the viscosity of the softened material, a lower release force can maintain the mechanical connection for a longer period than a higher release force.

[0042] If the connection point includes a positive locking connection of the components, the release device can be designed to heat the first component and / or the second component at the connection point to such an extent that it softens locally and a positive locking connection - for example a snap-fit ​​connection or a thread - between the two components is weakened.

[0043] If the joint includes a welded connection between the components, the release mechanism can be designed to release the weld between the two components. The joint can then, for example, resist the predetermined separating force for the predetermined duration due to the viscosity or surface tension of the molten material. Alternatively, the joint can include an additional mechanical connection besides the weld that resists the predetermined separating force for the predetermined duration.

[0044] If the joint comprises a frictional connection between the components, the release mechanism can be designed to reduce the surface normal force created by the frictional connection. For example, the joint comprises a (particularly cylindrical) convex region on the first component, which is arranged in a (particularly cylindrical) recess in the second component, wherein the convex region of the first component has a lower coefficient of thermal expansion than the material of the second component surrounding the recess. Heating the joint reduces the surface normal force and thus also the static friction between the contacting surfaces of the components.

[0045] The connection point and the release mechanism can be designed in such a way that the release mechanism can permanently damage and weaken the connection point and the mechanical connection between the components. In this case, the residual adhesion between the components is permanently and significantly reduced, even after the power supply to the release mechanism has ceased.

[0046] If the joint involves an adhesive or other material in a gap between the components, the removal device can chemically alter the material of the gap, thereby permanently weakening the joint. In an extreme example, the removal device heats the material in the gap so intensely that it burns. The force required for complete separation relies, for example, on a permanently reduced viscosity or strength of the chemically altered material in the gap.

[0047] Alternatively, the dissolving device heats the material in the joint so intensely that the material – partially or completely – emerges from the joint in liquid form or evaporates.

[0048] If the connection point includes a positive-locking connection between the components, the release device can be designed to heat the first component and / or the second component at the connection point to such an extent that it deforms there, permanently destroying or permanently deforming and thereby permanently weakening a positive-locking connection – for example, a snap-fit ​​connection or a thread – between the two components. In the event of complete destruction of the positive-locking connection, the connection point can include, in addition to the positive-locking connection, a further mechanical connection that resists the predetermined separating force for a predetermined duration.

[0049] If the joint includes a welded connection between the components, the release mechanism can be designed to irreversibly weaken or loosen the weld between the two components. If the release mechanism is designed to completely loosen the weld, the joint can include, in addition to the weld, a further mechanical connection that resists the predetermined separating force for the predetermined duration.

[0050] In the case of a material-bonded connection using adhesive or another material in a joint between the components, the joint is arranged and oriented in such a way that the material in the joint is subjected to shear stress by the separating force. For this purpose, the surface areas of the components bonded by the adhesive extend, in particular, parallel to the direction in which the components can be separated and in which the separating force is to be applied.

[0051] When handling medical instruments after their intended use, and when the mechanical connection weakens or partially loosens due to the release mechanism, separating forces can occur, particularly due to the inertia of all masses. This applies even with careful handling. To prevent unintentional separation of the components, the connection point and the release mechanism are designed so that mechanical separation occurs when a separating force of a predetermined magnitude acts for a predetermined duration. The components are not separated if the predetermined separating force acts for a shorter duration than the predetermined duration, or if a separating force smaller than the predetermined force acts during the predetermined duration.However, a lower separating force can cause mechanical separation after a longer period of time, and conversely, a higher separating force can cause mechanical separation after a shorter period of time.

[0052] In the case of a medical instrument such as the one described here, the force required to separate the weakened joint shall in particular not exceed one tenth, one twentieth, one fiftieth, or one hundredth of the force required to separate the original, non-weakened joint.

[0053] Such a pronounced weakening of the mechanical connection allows for easy separation, even in the case of a connection point that was originally designed to be robust, and in particular, purely manual separation. It may be possible to separate the weakened connection point without tools, namely with just gloves and a force that can easily be generated manually.

[0054] In the case of a medical instrument such as described herein, the weakened connection point, in particular, resists a separating force corresponding to 1.5 times, 2 times, or 3 times the weight of the medical instrument for a period of one second, two seconds, or five seconds.

[0055] The effects of these forces can easily be avoided by, for example, preventing jerky or jarring movements. This minimum robustness of the weakened connection point also makes accidental separation of the weakened connection point easily preventable.

[0056] In a medical instrument such as described here, the weakened mechanical connection, in particular, resists a separating force corresponding to 1.5 times, 2 times, or 3 times the weight of the less massive of the two components for a period of one second, two seconds, or five seconds.

[0057] In many cases, the central section of a medical instrument is clearly much heavier than its peripheral components. This is true, for example, of the flexible shaft of an endoscope used in gastroenterology. Medical personnel therefore often intuitively grasp the instrument by its heaviest component. In other cases, the rule to always grasp the instrument by its heaviest component is easy to communicate, quick to learn, and reliably implemented. The weight of the less massive end components is then so low that the force required for separation is not generated accidentally, and especially not dynamically. In particular, an impact force of 1.5, 2, or 3 times the weight of the less massive component can be easily avoided by not moving the instrument abruptly.

[0058] In a medical instrument such as described here, the weakened connection point resists, in particular, a separating force of 1 N or of 2 N or of 5 N or of 10 N for a period of one second or of two seconds or of five seconds.

[0059] For many medical instruments, the total mass of the instrument or the mass of the individual component to be separated from an adjacent component does not exceed 50 g (grams), corresponding to a force of approximately 0.5 N (newtons). Given the specified minimum robustness of the weakened connection, unintentional separation is easily avoided.

[0060] In the case of a medical instrument such as described here, the weakened connection point is separated, in particular, by a separating force corresponding to three, five, or ten times the weight of the medical instrument, within a period of one second, two seconds, or five seconds.

[0061] For the typical dimensions of many medical instruments, even three, five, or ten times the weight of the medical instrument can easily be generated manually for separation.

[0062] In a medical instrument such as described here, the weakened connection point is separated, in particular, by a separating force corresponding to three, five, or ten times the weight of the less massive of the two components, within a period of one second, two seconds, or five seconds.

[0063] For components of typical mass to be separated in many medical instruments, even three, five or ten times the weight force for separation can easily be generated manually.

[0064] In the case of a medical instrument such as described here, the weakened connection point can be separated, in particular, by a separating force of 5 N, 10 N, or 20 N within a time period of one second, two seconds, or five seconds.

[0065] A force of 5 N, 10 N, or 20 N can easily be generated manually.

[0066] In a medical instrument as described herein, the medical instrument consists in particular of a first component group consisting of or comprising the first component and a second component group consisting of or comprising the second component, wherein the weakened junction resists a separating force corresponding to 1.5 times, 2 times, or 3 times the weight force of the less massive of the two component groups for a period of one second, 2 seconds, or 5 seconds.

[0067] Since the medical instrument consists of the first component group and the second component group, it has no further components or component groups. Rather, the first component group and the second component group together constitute the medical instrument. If the first component group consists of the first component, then the first component group has no further components. Rather, then the first component alone constitutes the first component group. If the second component group consists of the second component, then the second component group has no further components. Rather, then the second component alone constitutes the second component group.

[0068] The advantages of a minimum robustness of the weakened connection point described above for the first component and the second component apply particularly to the minimum robustness of the weakened connection point between the two component groups of a medical instrument mentioned here.

[0069] In the case of a medical instrument as described herein, the medical instrument consists in particular of a first component group consisting of or comprising the first component and a second component group consisting of or comprising the second component, wherein the weakened connection point is separable by a separating force corresponding to three times, five times, or ten times the weight force of the less massive of the two component groups within a time period of one second, two seconds, or five seconds.

[0070] The advantages of separability of the weakened connection point described above for the first component and the second component apply particularly to the separability of the weakened connection point between the two component groups of a medical instrument mentioned here.

[0071] A medical instrument comprises a first component, a second component, a connection point between the first component and the second component for the mechanical connection of the first component and the second component, and a release device for releasing the mechanical connection formed by the connection point.

[0072] A medical instrument comprises a first component, a second component, a connection point between the first component and the second component, and a disassembly device for releasing the mechanical connection between the first component and the second component at the connection point and for partially or completely separating the second component from the first component.

[0073] Most of the options and variations shown above also apply to this medical instrument.

[0074] Breaking the mechanical connection between the two components is irreversible. Separating the two components can also be irreversible.

[0075] The disassembly device's process of breaking the mechanical connection between the components includes, in particular, damaging, weakening, or destroying the mechanical connection between the components. The disassembly device is specifically designed and configured to generate a force and / or torque that separates the two components, namely, a force driving them apart.

[0076] The loosening of the mechanical connection can involve the direct damage or destruction of a joint between the two components, for example, dissolving, melting, softening, or otherwise damaging or destroying an adhesive layer, a solder layer, or a weld. Alternatively or additionally, the loosening of the mechanical connection can involve damaging or destroying an area of ​​one of the two components immediately adjacent to a joint.

[0077] The disassembly device can be designed and configured to continuously generate a force and / or torque separating the two components. In this case, the force or torque is dimensioned such that it does not significantly stress, or at least does not overload, the connection point before it is released by the disassembly device, but overloads the weakened or damaged connection after it has been released by the disassembly device, thus forcing the two components apart.

[0078] Alternatively, the disassembly device can be designed and configured to generate a controllable force and / or torque separating the two components. The separating force or torque can be generated automatically, either simultaneously with or after the connection is released.

[0079] The disassembly device separates the two components from each other to such an extent that they no longer touch. Alternatively, the disassembly device moves the two components relative to each other only to such an extent that they still touch and are optionally also weakly mechanically connected, but can be completely separated from each other manually, for example, without any difficulty and, above all, with minimal force.

[0080] The connection point can also mechanically connect more than two components.

[0081] The disassembly device, with its functionality not only to release the mechanical connection between components but also to partially or completely separate them, can significantly simplify component separation. It can thus also support the reuse of materials, components, and assemblies, reduce resource consumption, and improve the acceptance of single-use instruments.

[0082] In the case of a medical instrument such as the one described here, the disassembly device includes in particular a release device for releasing the mechanical connection between the first component and the second component and a separation device for partially or completely separating the second component from the first component after releasing the mechanical connection.

[0083] The release device and the separation device are distinct devices. The release device can be directly adjacent to the separation device or arranged next to it. Alternatively, the release device can be spatially separated from the separation device.

[0084] Alternatively, the release device and the separation device can be partially identical, meaning that at least part of the release device can also be a separation device and at least part of the separation device can also be a release device.

[0085] The release device is arranged, in particular, directly adjacent to or near the connection point. Alternatively, the release device can be integrated with the connection point. Alternatively, the release device can be spatially separated from the connection point, especially if its release action is based on a remote effect, for example, on the chemical action of a substance released by the release device or the heating effect of electromagnetic radiation. Even if the effect of loosening the mechanical connection is based, for example, on heat generated by the release device and this heat is transferred to the connection point via a thermal conductor, the release device can be spatially separated from the connection point.

[0086] The separating device is arranged in particular directly adjacent to or near the connection point in order to be able to exert its intended spatially separating effect.

[0087] The joining device includes, in particular, a heating element. The heating element is, for example, a resistance wire or another electrical component across which a voltage drop occurs and which therefore releases heat as soon as an electric current flows through it. The heating element can be integrated with the joint, for example, embedded within it. Another example is a material-bonded connection using an electrically conductive thermoplastic as both the joining element and the heating element.

[0088] In a medical instrument such as described here, the separating device includes in particular a pre-tensioned spring or other pre-tensioned elastic component, the force of which partially or completely separates the second component from the first component.

[0089] The pre-tensioned spring or other pre-tensioned elastic component constantly generates a force that does not significantly stress the unreleased mechanical connection, but overloads the mechanical connection weakened or destroyed by the release device.

[0090] A pre-tensioned spring can simultaneously be used as a Bowden cable housing for a power transmission device if its coils are in contact with each other.

[0091] In a medical instrument such as the one described here, the separating device includes in particular a component which, when heated, generates a force that partially or completely separates the second component from the first component.

[0092] In the case of a medical instrument such as the one described here, the disassembly device shall in particular include at least either an electromechanical drive or an element made of bimetal or a shape memory material.

[0093] The electromechanical drive or the element made of bimetal or shape memory metal forms the separating device or is a component of the separating device.

[0094] An electromechanical drive comprises, in particular, an electric motor with a spindle drive, a linear motor, or an electromagnet in magnetic interaction with another magnet. The bimetallic or shape-memory metal element is activated, in particular, by heating, which simultaneously releases the mechanical connection.

[0095] In a medical instrument such as described herein, the connection point comprises in particular a positive-locking mechanical connection between the first component and the second component, wherein the disassembly device or the release device comprises a heating device which is integrated with or thermally connected to the connection point, for heating the connection point to a temperature at which the positive-locking mechanical connection is lost or weakened by softening or liquefaction.

[0096] The positive-locking mechanical connection includes in particular one or more retaining latches, catches, hooks or other snap connections between the components.

[0097] Latches, catches, hooks, or other locking mechanisms can each be partially or fully integrated with one of the components. In particular, the latches, catches, hooks, or other locking mechanisms are made of thermoplastic, which is melted or sufficiently softened by the heating device to weaken or release the mechanical connection. Complete melting is not strictly necessary.

[0098] In the case of a medical instrument, as described here, the connection point includes in particular a material-bonded mechanical connection between the first component and the second component.

[0099] The material-bonded mechanical connection includes, in particular, an adhesive connection, a soldered connection or a welded connection.

[0100] In a medical instrument such as described herein, the connection point comprises in particular an adhesive bond between the first component and the second component, wherein the disassembly device or the release device comprises a heating device which is integrated with or thermally connected to the adhesive bond for heating the adhesive bond, and wherein the adhesive bond is designed to become embrittled upon heating.

[0101] A medical instrument comprises a first component, a second component, an adhesive joint between the first component and the second component, and a heating device which is mechanically integrated with the adhesive joint or thermally connected to it for heating the adhesive joint, wherein the adhesive joint is designed to become embrittled when heated.

[0102] Embrittlement can weaken the adhesive bond to such an extent that it can subsequently be cut, in particular broken, manually with minimal effort and without the use of tools, or possibly by the cutting device.

[0103] In a medical instrument such as described here, the connection point includes in particular an adhesive layer, wherein the heating device consists of a wire or strand and is embedded in the adhesive layer.

[0104] When the wire or strand is loosened, a heating current flows through it, especially along its entire length.

[0105] The adhesive bond therefore comprises not only electrically conductive particles, fibers, or wire segments through which an electric current flows in a random pattern caused by random contact between the particles, fibers, or wire segments, but a single wire or strand whose entire length is electrically connected in series. This can allow for a less random and thus more uniform heat input, even with very small layer thicknesses, and consequently, a very thin adhesive layer.

[0106] Depending on the spatial shape of the adhesive layer, the wire or strand is arranged in a helix, spiral, or meandering shape.

[0107] Directly embedding the heating element in the adhesive layer optimizes heat transfer to the adhesive layer and minimizes the time and energy required to weaken or destroy the adhesive layer.

[0108] In a medical instrument such as described here, the connection point comprises in particular a cylindrical adhesive layer, wherein the heating device comprises a coil which is embedded in the cylindrical adhesive layer or which lies flat opposite the cylindrical adhesive layer in the immediate vicinity.

[0109] A cylindrical adhesive layer is particularly suitable for the material-bonded mechanical connection of two pipes or of a pipe in a bore or of a stud in a pipe.

[0110] In a medical instrument as described here, the adhesive bond is formed in particular by an electrically conductive adhesive in its cured state, wherein the first component is electrically conductive or has an electrically conductive area immediately adjacent to the adhesive, wherein the second component is electrically conductive or has an electrically conductive area immediately adjacent to the adhesive, wherein the electrically conductive first component or the electrically conductive area of ​​the first component immediately adjacent to the adhesive on the one hand, and the electrically conductive second component or the electrically conductive area of ​​the second component immediately adjacent to the adhesive on the other hand, are connected electrically only by the adhesive, so that a current can be conducted through the adhesive via the first component and the second component, which heats the adhesive.

[0111] In this case, the electrically conductive, cured adhesive itself constitutes a heating device.

[0112] Connecting the electrically conductive, cured adhesive to electrically conductive components can be particularly simple, as no additional conductors are required. The electrically conductive components themselves can also be connected very easily, provided their outer surfaces are clean.

[0113] Contacting the electrically conductive adhesive via electrically conductive areas on the components allows for almost any desired current direction within the adhesive, depending on the design of these conductive areas. If the conductive areas are planar, the adhesive can flow in the direction of its thickness, as is the case with electrically conductive components. Alternatively, the conductive areas can be arranged so that the adhesive flows through the layer essentially parallel to the layer it forms. In the case of a cylindrical adhesive layer, the conductive areas can be arranged in a ring shape at the edges of the adhesive layer, so that the adhesive layer carries current in a direction parallel to the axis of symmetry of the cylinder.

[0114] A medical instrument such as described here is in particular an endoscope with a shaft, wherein the shaft or a part of the shaft forms the first component.

[0115] The shaft can be completely rigid, partially or completely flexible.

[0120] The printed circuit board (PCB) can be rigid or flexible. It can contain electrical or electronic components or be mechanically and electrically connected to them. Electronic components include, for example, a light source, an image sensor, another sensor, and a connector. The PCB can extend from a proximal end to a distal end of the medical instrument and, similar to a cable, may be designed and configured to transmit power, control signals, image signals, or other sensor signals.

[0121] In the case of a medical instrument such as the one described here, the second component includes, in particular, an image sensor or an electrical conductor or cable.

[0122] In particular, the second component is an image sensor, an electrical line, or a cable.

[0123] In a medical instrument like the one described here, a heating device for melting solder is integrated into the circuit board.

[0124] The heating element includes, in particular, conductive traces designed as heating resistors. These conductive traces are arranged either locally under individual solder pads of the printed circuit boards or under an entire surface area with many solder pads for connection to, for example, an image sensor.

[0125] The heating element can melt solder from solder joints between the circuit board and, for example, an image sensor. This can enable both the removal of an electronic component from the circuit board and the placement of an electronic component on the circuit board.

[0126] In the case of a medical instrument as described here, the medical instrument is in particular a heated tubing set, the first component being a splitter.

[0127] A splitter is a component for connecting at least three hoses, pipes, or other devices, allowing or specifying different paths for fluid, energy, and / or signal flows. For example, the splitter specifies a path for a fluid flow from a first coupling to a hose, and for an energy flow, a path from a second coupling to a heating element within the hose.

[0130] In a medical instrument as described herein, the first component is specifically designed and configured to transmit a force or torque from a proximal end region to a distal end region of the medical instrument and is electrically conductive, wherein the first component is designed and configured to conduct an electric current to heat and thereby loosen the connection point, and wherein the medical instrument further comprises an electrical contacting device for contacting the first component and introducing an electric current into the first component.

[0131] A medical instrument comprises a transmission device designed and configured to transmit at least either a force or a torque from a proximal end region to a distal end region of the medical instrument, movable relative to a shaft of the medical instrument, and electrically conductive; a connection point mechanically connecting a first component and a second component; and an electrical contacting device for contacting the transmission device and introducing an electric current to transfer electrical power into the transmission device, wherein the transmission device is designed and configured to conduct the electric current and the electrical power heats the connection point to break the mechanical connection between the first component and the second component.

[0133] Most of the options and variations shown above also apply to this medical instrument.

[0134] The second component is located, in particular, at a distal end of the medical instrument. Alternatively, the second component can be located at a proximal end of the medical instrument. The connection point that mechanically and, in particular, electrically connects the first and second components is, in particular, an adhesive or soldered connection.

[0135] The second component is in particular a lever or wheel or other device that can be operated directly or indirectly by hand or by motor in a proximal end area of ​​the medical instrument, especially in a handling device.

[0136] The contacting device comprises, in particular, a stationary sliding contact against which the first component rests, or conversely, a sliding contact integrated with or rigidly connected to the first component, which rests against a stationary contact area. Alternatively, the contacting device comprises, for example, a flexible conductor, a lever, or a wheel for force transmission, which is simultaneously designed and configured for contacting.

[0137] The connection point must be designed to simultaneously conduct the current carried by the first component. Due to its electrical resistance, the connection point itself can also act as a heating element to warm itself. Alternatively, a heating resistor can be provided adjacent to or directly connected to the connection point to heat it, thereby weakening or destroying it and thus breaking the mechanical connection.

[0138] In the case of a medical instrument such as the one described here, the first component is subjected to tensile stress, in particular exclusively or predominantly, during its intended use.

[0139] In a medical instrument such as the one described here, the first component is subjected to tensile stress, particularly when generating the intended effect of the medical instrument.

[0140] The intended effect is, in particular, cutting, crushing, punching, gripping of fabric or bending or pivoting of a shaft section.

[0141] In a medical instrument such as the one described here, the first component is in particular an electrically conductive pulley or pull wire.

[0142] A Bowden cable core is also a cable or wire that runs smoothly and with minimal play in a guide tube or hose. Optionally, a Bowden cable core can be designed to transmit compressive forces with minimal loss, even with only slight compression.

[0143] In the case of a medical instrument such as the one described here, at least either the first component or the second component is designed and configured as a separating device for separating the second component from the first component after the connection point has been released.

[0144] Energy stored in an elastically prestressed component can cause the two components to separate after the connection is released. For example, a previously tensioned cable or pull wire, or a tensioned Bowden cable core, will detach itself from the second component automatically when the mechanical connection to it is released.

[0145] In a medical instrument such as the one described here, the first component and the connection point, and if applicable a heating device at the connection point, are designed in such a way that an electric current flowing in the first component heats the connection point more than the first component.

[0146] The current heats the junction more than the first component if the temperature of the junction rises faster or reaches a higher value than the temperature of the first component.

[0147] Especially if the second component is also carrying the same electric current, the second component is also designed in such a way that the electric current heats the connection point more than the second component.

[0148] In a medical instrument such as the one described here, the electrical resistance of the junction or of a heating resistor thermally connected to the junction is, in particular, greater than the electrical resistance of the first component or of a section of the first component whose length is equal to the largest linear dimension of the junction in the current direction.

[0149] Alternatively or additionally, thermal insulation of the connection point and thermal coupling of the first component to its environment can ensure that the connection point heats up more than the first component and especially also more than the second component.

[0150] A medical instrument as described herein further includes, in particular, an interface for receiving electrical power for disassembling the medical instrument ().

[0151] A medical instrument comprises a first component, a second component, a connection point between the first component and the second component, a release device for receiving electrical power and for weakening or releasing the mechanical connection between the first component and the second component at the connection point, and an interface for receiving electrical power for the release device.

[0156] A medical instrument as described herein further includes, in particular, a device for locking the mechanical connection between the interface of the medical instrument and a corresponding interface of a supply unit.

[0157] A locking mechanism can prevent separation of the interfaces using forces typically applied manually. Alternatively, a locking mechanism can make separation of the interfaces significantly more difficult. This can signal to a person using or disassembling the medical system (consisting of the medical instrument and supply unit) that their action is undesirable.

[0158] A locking mechanism on the mechanical connection of the interfaces can help enforce or increase the likelihood of a desired sequence of events. For example, the lock can be released only after power has been supplied to the release mechanism. This, in turn, can simplify the disassembly of the medical instrument while simultaneously preventing the reuse of a single-use medical instrument, thus significantly improving hygiene and substantially reducing the risk of infection for patients.

[0159] In the case of a medical instrument such as the one described here, the locking device includes at least either a recess for receiving a latch or a magnet.

[0160] One or more (e.g., symmetrically arranged) recesses for one or more corresponding locking bolts can enable reliable locking of the mechanical connection between the interfaces. The locking bolt(s) are located at the interface of the supply unit and are movable relative to it.

[0161] Alternatively or additionally, the interface of the medical instrument can have a magnet that can be attracted to a corresponding magnet at the corresponding interface of the supply unit in order to hold the interface of the medical instrument to the interface of the supply unit. The magnet at the interface of the medical instrument is, in particular, designed as a permanent magnet or as an electromagnet.

[0162] A medical instrument as described herein shall in particular further include a device for generating at least either a signal indicating whether the release device is receiving or has received electrical power, or a signal indicating whether the mechanical connection between the first component () and the second component () has been released.

[0171] A supply unit as described here further includes, in particular, a locking device for locking a mechanical connection between the interface of the supply unit and a corresponding interface of the medical instrument.

[0172] The locking device includes, for example, an electromagnetically or electromechanically movable latch or hook for locking the interface of the medical instrument to the interface of the supply unit. Alternatively, the locking device may, for example, include an electromagnet at the interface of the supply unit that interacts with a magnet at the interface of the medical instrument.

[0173] A supply unit as described herein further includes, in particular, a locking control for controlling the locking device, wherein the locking control is designed to release the locking only after power has been provided to the disassembly device of the medical instrument.

[0174] The locking control is specifically designed and configured to receive a signal indicating whether the release device is receiving or has received electrical power, or indicating whether the mechanical connection between the first component and the second component of the medical instrument has been released.

[0175] The locking mechanism ensures that a medical instrument can only be disconnected from the supply unit after use once the mechanical connection between a first and second component of the medical instrument has been released. This simplifies the subsequent disassembly of the used medical instrument and prevents its reuse, thus preventing the risk of infection.

[0176] A medical system comprises a medical instrument, as described here, and a supply unit, as described here.

[0177] A disposal device for the disassembled disposal of medical instruments comprises several containers for receiving different components of a medical instrument to be disposed of and a device for assisting the disassembly of the medical instrument to be disposed of from several joined components by separating at at least one predetermined connection point.

[0181] Alternatively, the sensor can be coupled to an interface of the disposal device, which can be connected to a corresponding interface of a medical instrument. This interface of the medical instrument is specifically designed to receive power and / or control signals from a power supply unit for the intended operation of the medical instrument during its intended use, and to receive power for a disassembly device when the medical instrument is disassembled. The interface of the medical instrument can further be designed and configured to provide information about the identity or type of the medical instrument to the disposal device via its corresponding interface. This information is transmitted, in particular, in the form of electrical or optical signals.This information is received by the sensor. The medical instrument identifies itself or its type by receiving or using this information.

[0182] The sensor generates a type signal that identifies the detected type of medical instrument or its component, or an identity signal that represents the detected identity of the medical instrument or component.

[0183] A signal output of the sensor, at which the sensor provides the type or identity signal, is coupled to a signal input of the device for assisting disassembly, for example by an electrical or optical signal line.

[0184] The recorded identity or type of the medical instrument or its component is used by the facility to support disassembly, depending on the identity or type.

[0186] The signaling device is designed and configured, for example, to generate a colored and / or time-modulated light signal or to display a pictogram or text such as "Deposit here," "Here," "Yes," or "No." For ease of identification, the display device is positioned directly at the entrance opening. Alternatively, the signaling device's position relative to the entrance opening can be indicated, for example, by an arrow or a line. The signaling device can partially or completely surround the entrance opening, for example, as a ring-shaped light signal.

[0187] In particular, each container's inlet opening is assigned its own signaling device.

[0188] The signal control is specifically designed and configured to control the signaling device or devices depending on the detected identity or type of a component of a medical instrument.

The signal output may be designed and configured to provide the image and / or sound signal as an electrical, optical, or electromagnetic signal.

[0191] The output control primarily governs the display of manual and optionally machine-assisted steps in the dismantling and disposal process. Furthermore, the output control can adjust the display of the dismantling steps based on the current stage of dismantling.

[0192] In a disposal device such as the one described here, the output control is coupled in particular to the sensor in order to receive an identity signal or a type signal from the sensor and to control the output device depending on the identity signal or the type signal.

[0193] The output controller can only be designed and configured to support a single type of medical instrument. If the identification or type signal indicates a different type, disassembly of the medical instrument will not be supported.

[0194] Alternatively, the dispensing controller can be designed and configured to support multiple types of medical instruments. In this case, the dispensing controller directs the dispensing device based on the detected identity or type to display the disassembly and disposal steps specific to that type.

[0195] A disposal device as described here further includes, in particular, a contour mask at an entrance to one of the containers, which at least either makes it recognizable for which component the container is intended, or hinders or prevents the passage of another component.

[0196] For example, the contour mask at the inlet opening of a container intended for shafts has only a small cross-sectional bore, which is only slightly larger than the outer cross-sections of the shafts of medical instruments to be disposed of.

[0206] For irradiation, the treatment device may have a radiation source that generates X-rays, ultraviolet radiation, or microwaves. The irradiation can have a partially, predominantly, or exclusively physical effect, and a partially, predominantly, or exclusively chemical effect. For example, the irradiation can heat components or their fragments, split molecules, or trigger chemical reactions. Thus, the irradiation can also have an indirect biological effect, particularly a germicidal and sterilizing effect. Therefore, the irradiation can reduce the risk of infection emanating from the container and its contents.

[0207] For sonication, the treatment device can, for example, include an ultrasound source. Ultrasound can cause or assist the removal of adhering contaminants or the separation of components within a part.

[0208] For wetting, the treatment device may have one or more nozzles through which a solvent, acid, base, other chemical reagent or disinfectant can be sprayed, dripped or injected onto the component or its constituent parts.

[0217] In a disposal device such as the one described here, the mixing control is specifically designed to detect the power consumption of the mixing device and to control the mixing device depending on the power consumption.

[0218] The mixing control system can, for example, measure the current draw of the mixing unit at a given supply voltage, the voltage drop across the mixing unit at a given current, or the rotational speed of the mixing unit. The rotational speed can be directly measured using a sensor or calculated from the frequency of fluctuations in the mixing unit's current draw.

[0221] In a disposal device such as the one described here, in particular the entrance opening to one of the several containers is designed in a funnel shape.

[0222] A funnel-shaped design of the inlet opening can simplify the insertion of the component intended for the container.

[0223] The funnel-shaped inlet opening can be integrated with the contoured plate, thus tapering to the contour of the intended component. This simultaneously simplifies the insertion of the component intended for the container and makes it more difficult or prevents the insertion of other components into the container.

[0236] The first component can be the transmission device itself. The connection point is, in particular, a joint between a distal end region of the transmission device (the first component) and a second component.

[0237] Heating causes, in particular, a liquefaction of a solder or a weld seam, an embrittlement of an adhesive in an adhesive joint, or a reduction of a pressing force on a friction-fit connection due to different coefficients of thermal expansion.

Description of the embodiments

[0259] Fig. Figure 1 shows a schematic representation of a medical system consisting of a medical instrument, namely an endoscope 10, and a supply unit 100. A distal end region 12 of the endoscope 10 is formed by a distal end component 20 of a shaft 13. In the example shown, the shaft 13 is flexible. The shaft 13 extends to a proximal end region 14 of the endoscope 10, which is formed by a handling device 40.

[0260] The handling device 40 of the medical instrument 10 is connected to the supply device 100 by a cable 50. In the example shown, a distal end region 51 of the cable 50 is permanently connected to the handling device 40. The connection between the distal end region 51 of the cable 50 and the handling device 40 is permanent in that it cannot be separated non-destructively. Destructive separation can be achieved similarly to the following example: Fig. 2 to 5 and 7 to 10 may be possible as described.

[0261] A connector 57 is provided at a proximal end region 55 of the cable 50. The power supply unit 100 has a corresponding connector 107. Both connectors 57 and 107 have, for example, corresponding contact pins and sockets. The mechanical connection between the two connectors 57 and 107 can be achieved solely by friction between electrical contact surfaces and / or between other corresponding surface areas. Additionally, a snap-fit ​​connection and / or a screw connection or a locking mechanism can be provided. Alternatively or additionally, a (particularly electrically) controllable positive locking or magnetic locking mechanism can be provided, as is also shown in the figures described below.

[0262] In the Fig. In the configuration shown, connector 57 on cable 50 is connected to connector 107 on power supply unit 100. In this configuration, the intended use of the medical instrument 10 is possible. After the intended single use of the medical instrument 10, connector 57 on cable 50 of the medical instrument 10 is disconnected from the corresponding connector 107 on the power supply unit 100, and the medical instrument 10 is disposed of. The power supply unit 100 can be reused. As described below, disassembly of the medical instrument 10 can be prepared or carried out before disconnecting connectors 57 and 107.

[0263] The power supply unit 100 includes a first power source 102 for providing electrical power to the medical instrument 10. The first power source 102 can be designed and configured to provide electrical power to a light source, an image sensor, or a camera of the medical instrument.

[0264] Contrary to the representation in Fig. 1. Alternatively or additionally, the supply unit 100 may have a power source for providing light. This light is, for example, illumination light, laser light, or other high-intensity light for direct physical and transformative interaction with tissue.

[0265] If the medical instrument 1 differs from the illustration in Fig. 1 For example, if the instrument is an electrosurgical instrument, the first power source 102 of the supply unit 100 may be designed and equipped to provide electrical power for electrocautery.

[0266] The supply unit 100 further comprises a camera control unit 104 – often also referred to as a CCU. The camera control unit 104 is designed and configured to provide control signals for one or more image sensors or cameras of the medical instrument 10. The camera control unit 104 is further designed and configured to receive, optionally amplify, or otherwise process, store, process, combine, or superimpose analog or digital image signals from the one or more image sensors or cameras of the medical instrument 10. The camera control unit 104 is further designed and configured to generate image signals for one or more displays, projectors, video glasses, or other image output devices that are located in Fig. 1 are not shown.

[0267] Supply unit 100 also has a second power source 106 for a Fig. Figure 1 shows a disassembly device for the medical instrument 10 (not shown). The second power source 106 is designed to provide power not during the intended use of the medical instrument 10 in a medical procedure, but only after its completion, in order to effect or assist in the disassembly of the medical instrument 10. The second power source 106 generates, for example, electrical power for heating and melting a solder, for heating and melting or softening a plastic, for heating and embrittlement of a plastic, for heating a bimetallic element or a shape-memory metal element, or for driving an electric motor in or on the medical instrument 10.

[0268] The power for the intended operation and the power for the disassembly device of the medical instrument 10 can be provided via different paths, for example, via at least partially different contacts or wires of the connector 107. The power for the intended operation and the power for the disassembly device of the medical instrument 10 can be provided in different ways, for example, in one case as light, in the other case electrically, or with different electrical polarities, voltages, currents, or frequencies.

[0269] The power supply unit 100 also includes a control unit 108, for example a microprocessor, a controller, or a computer, which is coupled to the first power source 102, the camera control unit 104, and the second power source 106. The control unit 108 can be configured as shown in Fig. 1 may be coupled in a star-shaped manner by individual point-to-point connections, by a bus system or in another way with the other components, assemblies and functional units of the supply unit 100.

[0270] The supply unit 100 further comprises a user interface 110 for providing information to a person using the medical system 10, 100 and for receiving input from that person. The user interface 110 may include a display or other optical output device, or an interface to a display or other optical output device, a loudspeaker or other acoustic output device, or an interface to an acoustic output device. The user interface 110 may also include one or more manually operated buttons, rocker switches, rotatable, pivotable, or translatable controls, or a touch-sensitive surface—for example, a display device.

[0271] The user interface 110 is designed and equipped to control the medical system 10, 100 during its intended use, during a medical procedure and / or to configure the medical system 10, 100.

[0272] The user interface is further designed and configured to receive an input by which a person using the medical system 10, 100 indicates the end of the intended use of the medical instrument 10. This input can trigger the provision of power by the second power source 106 to a disassembly device for the medical instrument 10. Furthermore, this input can trigger a subsequent unlocking of the mechanical connection between the connector 57 at the proximal end 55 of the cable 50 on the one hand and the corresponding connector 107 on the power supply unit 100 on the other.The control of the timing sequence of the provision of power by the second power source 106 for a disassembly device of the medical instrument 10 and the unlocking of the mechanical connection between the connector 57 at the proximal end region 55 of the cable 50 of the medical instrument 10 on the one hand and the connector 107 of the supply unit 100 on the other hand is carried out in particular by the control 108 of the supply unit 100.

[0273] Contrary to the representation in Fig. 1. The first power source 102, the camera control unit 104, the second power source 106, the controller 108, and the user interface 110 of the power supply unit 100 can be partially or fully integrated. For example, the first power source 102 and the second power source 106 can be implemented as a single power source. This single power source can be controllably provided either for the intended operation during the intended use of the medical instrument 10 or for a disassembly device for the medical instrument 10.

[0274] Fig. Figure 2 shows a schematic and enlarged representation of an embodiment of the distal end component 20 of the shaft and a proximally adjoining area of ​​an outer shaft 30 of the medical instrument 10. Fig. 1. The distal end component 20 of the shaft and the outer shaft 30 are shown in cross-section, so that components within them are visible. In the example shown, the distal end component 20 of the shaft forms a rigid unit, i.e., exhibiting low elasticity. The distal end component 20 is in Fig. 2 is represented primarily by its housing with a window component indicated on the distal front face.

[0275] The outer shaft 30 and the components arranged within it are flexible, creating a flexibility of the shaft that is advantageous, for example, for examinations of the digestive tract. Near the distal end component 20 of the shaft, the outer shaft 30 exhibits increased flexibility, for example, due to the Fig. 2. Indicated reduced wall thickness in several ring-shaped areas. 32. Within the outer shaft, a [missing word] can be found. Fig. 2. A support structure not shown and / or a joint for absorbing compressive forces and ensuring a defined deformation may be provided.

[0276] The distal end component 20 of the shaft comprises a camera device with a lens 23 and an image sensor 24. The image sensor 24 is mechanically and electrically connected to a distal end of a flexible printed circuit board 25 by numerous solder joints. The solder joints are configured, for example, as a ball grid array. Further electrical and electronic components can be provided on the flexible printed circuit board 25, which are arranged in Fig. 2 are not shown. The flexible circuit board 25 extends, in particular within the lumen of the outer shaft 30, to the proximal end region 14 of the medical instrument 10 and to the distal end region 51 of the cable 50 (cf. Fig. 1) In the proximal end region 14 of the medical instrument 10, conductor tracks of the flexible circuit board 25 can be directly or indirectly connected to electrical conductors of the cable 50, for example, by soldered, plug-in, clamped, or crimped connections. Alternatively, the flexible circuit board 25 can extend to the connector 57 at the proximal end region 55 of the cable 50. Conductor tracks on and in the flexible circuit board 25 can enable the transmission of electrical power and control signals to the image sensor 24 and the transmission of image signals from the image sensor 24 to the proximal end region 14 of the medical instrument 10.

[0277] A proximal edge region 26 of the distal end component 20 of the shaft 13 is mechanically connected to a distal edge region 36 of the outer shaft 30. In the illustrated example, the proximal edge region 26 of the distal end component 20 and the distal edge region 36 of the outer shaft 30 overlap. An adhesive layer 62 is provided between opposing surface regions of the proximal edge region 26 of the distal end component 20 on the one hand and the distal edge region 36 of the outer shaft 30 on the other, bonding the two. In the illustrated example, a compressed helical spring 81 is also provided in a cavity between the proximal edge region 26 of the distal end component 20 and the distal edge region 36 of the outer shaft 30.

[0278] In the outer shaft 30 several transmission devices 33 are provided, which are separated from the handling device 40 (see Fig. 1) extend to the distal end component 20 of the shaft 13. The transmission devices 33 are designed and configured to transmit forces and movements and are therefore displaceable in their longitudinal direction relative to the outer shaft 30. These forces and movements are generated, in particular, at the handling device 40, for example, manually by rotating one or more wheels, pivoting one or more levers, or moving one or more displaceable components. Alternatively, the forces or movements can be generated by a motor. The transmission devices 33 can be operated by means of Fig. 1. The transmission devices (not shown) are guided in such a way that they can only move in their longitudinal direction. Examples of transmission devices are steel wires or steel strands.

[0279] The distal ends 34 of the transmission devices 33 are mechanically connected to the distal end component 20 of the shaft 13, in the illustrated example by plumb line 61. Due to the increased flexibility of the outer shaft 13 at the annular areas 32, the distal end component 20 of the shaft 13 can be pivoted by the forces and movements transmitted by the transmission devices 33. A downward pivoted position is indicated by a dashed contour as an example of such a pivoting movement.

[0280] The transmission devices 33 are electrically conductive, so that they are suitable not only for transmitting forces and movements but also for transmitting electrical power to the distal end component 20 of the shaft 13. The distal ends 34 of the transmission devices 33 are electrically connected to each other exclusively via heating resistors 71. The heating resistors 71 are thermally coupled to the adhesive layer 62, which mechanically connects the proximal edge region 26 of the distal end component 20 to the distal edge region 36 of the outer shaft 30, and to the solder 61, which mechanically connects the distal ends 34 of the transmission devices 33 to the distal end component 20 of the shaft 13. For this purpose, the heating resistors 71 are arranged in close proximity to the adhesive layer 62 and the solder 61. The heating resistors 71 form a heating device for heating the solder 61 and the adhesive layer 62.

[0281] At the in Fig. In the example shown, the pivotability of the distal end of the shaft 13 is due to a flexibility of the outer shaft 30 and optionally a Fig. 2. Joint not shown in the outer shaft 30. Alternatively and deviating from the illustration in Fig. 2. The pivotability of the distal end of the shaft 13 can be realized in the distal end component 20 itself. For this purpose, the distal end component 20 has, in particular, at least in some areas, a flexible material and optionally one or more areas with reduced wall thickness. This corresponds to a design compared to the illustration in Fig. 2. Inverted arrangement of the mechanical interface between distal end component 20 and outer shaft 30 (especially the adhesive layer 62) on the one hand and the ring-shaped areas 32 with reduced wall thickness on the other.

[0282] Fig. Figure 3 shows a further schematic representation of the distal end component 20 of the shaft 13 and the outer shaft 30 of the medical instrument 10. Fig. 2. The type of presentation corresponds to that of the Fig. 2.

[0283] In Fig. Figure 3, however, depicts a situation that arises after the heating device formed by the heating resistors 71 is supplied with electrical power by the second power source 106 of the supply unit 100, and the adhesive layer 62 has been heated until it softens and the solder 61 until it melts. The melting of the solder 61 releases the mechanical connection between the distal ends 34 of the transmission devices 33 and the distal end component 20 of the shaft 13. Simultaneously, the softening of the adhesive layer 62 largely eliminates the mechanical connection between the distal end component 20 of the shaft 13 and the outer shaft 30. As a result, the elastic restoring force of the initially compressed helical spring 81 is sufficient to separate the distal end component 20 from the outer shaft 30.In this way, the heating resistors 71 act as a release device to release the mechanical connection and the originally compressed helical spring 81 as a separating device.

[0284] The flexible circuit board 25 can remain mechanically connected to the distal end component 20 of the shaft 13 and then be pulled distally out of the outer shaft 30. Alternatively, the flexible circuit board 25 can be separated from the distal end component 20 of the shaft 13, in particular from the image sensor 24, for example as shown in the Fig. 6 shown.

[0285] Contrary to the representation in Fig. 3. The helical spring 81 can be designed to detach the end component 20 only partially, rather than completely, from the outer shaft 30. In this case, even after the originally compressed helical spring 81 has fully relaxed, a (particularly small) overlap remains between the proximal edge region 26 of the distal end component 20 and the distal edge region 36 of the outer shaft 30. A small portion of the adhesive layer 62 then continues to connect the proximal edge region 26 of the distal end component 20 and the distal edge region 36 of the outer shaft 30. Thus, a significantly weakened mechanical connection remains. The helical spring 81 and the adhesive layer 62 are dimensioned such that the distal end component 20 cannot easily fall off, but can be separated from the outer shaft 30 with a force that can be easily generated manually.

[0286] Fig. Figure 4 shows a schematic and enlarged representation of a further embodiment of the distal end component 20 of the shaft 13 and a proximally adjoining area of ​​the outer shaft 30 of the medical instrument 10. Fig. 1. The type of presentation in Fig. 4 corresponds to that of the Fig. 2 and Fig. 3. The in Fig. The embodiment shown in section 4 is similar in some features, properties and functions to the one shown in the Fig. 2 and Fig. The following are the main differences compared to the embodiment shown in section 3. Fig. 2 and Fig. 3. This is described in the illustrated embodiment.

[0287] At the in Fig. In the embodiment shown in Figure 4, the adhesive layer 62 between the proximal edge region 26 of the distal end component 20 and the distal edge region 36 of the outer shaft 30 is electrically conductive. At least the surface areas of the distal end component 20 and the outer shaft 30 immediately adjacent to the adhesive layer 62 are electrically conductive. They contact the adhesive layer 62 and allow electrical power to be supplied to it. The electrically conductive adhesive layer 62 can be heated by the supplied electrical power to a temperature at which it softens or liquefies, or otherwise loses its ability to transmit forces and torques, for example, by becoming brittle.

[0288] At the in Fig. In the embodiment shown in Figure 4, the housing of the distal end 20 is electrically conductive, and the outer shaft 30, which otherwise consists at least predominantly of an electrically insulating material, has an electrically conductive coating 31. The electrically conductive surface of the distal end component 20 and the electrically conductive coating 31 of the outer shaft 30 are located opposite each other over a large area at a relatively small distance. This allows an electric current to flow in the essentially circular cylindrical adhesive layer 62, primarily in a radial direction. The contact between the distal end component 20 and the electrically conductive coating 31 of the outer shaft 30 is in Fig. 4 not shown.

[0289] Fig. Figure 5 shows a schematic and enlarged representation of a further embodiment of the distal end component 20 of the shaft 13 and a proximally adjoining area of ​​the outer shaft 30 of the medical instrument 10. Fig. 1. The type of presentation in Fig. 5 corresponds to that of the Fig. 2 to 4. That in Fig. The embodiment shown in section 5 is similar in some features, properties and functions to the one shown in the Fig. 2 and Fig. 3 illustrated embodiment and even more so the one based on the Fig. 4 illustrated embodiment.

[0290] The following are, in particular, differences compared to the one based on the Fig. 4. This is described in the illustrated embodiment.

[0291] As with the one based on the Fig. The example shown in 4 is also the one in Fig. In the embodiment shown in section 5, the adhesive layer 62 between the proximal edge region 26 of the distal end component 20 and the distal edge region 36 of the outer shaft 30 is electrically conductive. Unlike the embodiment shown in the Fig. The four examples shown are from the one in Fig. In the example shown in Figure 5, the distal end component 20 of the shaft 13 and the outer shaft 30, or at least their surface areas bordering the adhesive layer 62, are largely electrically insulating. Only a narrow annular surface area 31 of the outer shaft 30 at the proximal edge of the cylindrical adhesive layer 62 and a narrow annular surface area 21 of the distal end component 20 at the distal edge of the cylindrical adhesive layer 62 are electrically conductive. This allows an electric current to flow in the essentially circular cylindrical adhesive layer 62, primarily in an axial direction.

[0292] The contacting of the electrically conductive annular surface area 21 of the distal end component 20 and the electrically conductive annular surface area 31 of the outer shaft 30 are in Fig. 5 not shown.

[0293] Contrary to the representations based on the Fig. In cases 2 to 5, the coil spring 81 can be omitted. In this case, the adhesive layer 62 is chemically altered by the heating provided by the heating resistors 71 to such an extent that the mechanical connection between the distal end region 20 and the outer shaft 30 is permanently and significantly weakened. A separating force, which can easily be generated manually, is sufficient to break the weakened connection.

[0294] Alternatively, the mechanical connection is permanently and significantly weakened by partial outflow or evaporation of the adhesive 62 from the joint between the proximal edge region 26 of the distal end region 20 and the distal end region 36 of the outer shaft 30. A separating force, which can easily be generated manually, is then sufficient to separate the weakened connection.

[0295] Alternatively, the mechanical connection is temporarily weakened significantly by temporarily softening the adhesive 62 between the proximal edge region 26 of the distal end region 20 and the distal end region 36 of the outer shaft 30. During the heating of the adhesive 62, a separating force that can easily be generated manually is sufficient to separate the weakened connection.

[0296] Fig. Figure 6 shows a schematic top view of the distal end region of the in the Fig. The flexible printed circuit board 25 shown in sections 2 to 5 serves as an example of a printed circuit board for a medical instrument that is to be disassembled for disposal after a single use. The drawing plane of the Fig. 6 is orthogonal to the cutting planes of the Fig. 2 to 5 and parallel to the light-sensitive plane of the image sensor 24. For the sake of clarity and in accordance with the schematic nature of the illustrations, the number of solder contacts is different from the Fig. Reduced by 2 to 5.

[0297] At the in Fig. The surface of the flexible printed circuit board 25 shown in Figure 6 is provided with contact pads or contact surfaces 27, which are located in Fig. 6 are indicated as circles. Each contact surface 27 is designed to be mechanically and electrically connected by means of a solder bead to a corresponding contact surface on the back of the image sensor 24 facing the flexible circuit board 25. The actual number of contact surfaces 27 may be lower or significantly higher than shown. Fig. 5 indicated. The contact surfaces 27 are arranged in a rectangular grid and are intended to form a ball grid array.

[0298] The flexible printed circuit board 25 has numerous features in one or more layers. Fig. 6 conductor tracks (not shown), in particular for contacting the contact surfaces 27. The flexible circuit board 25 also has a conductor track 72, which is located in Fig. 6 is shown and is electrically insulated from the contact surfaces 27. For this purpose, it is formed in a layer within the flexible printed circuit board 25, which is electrically insulated from the contact surfaces 27. Simultaneously, the conductor track 72 is thermally coupled to the contact surfaces 27 to enable effective heat transfer to the contact surfaces 27. For this purpose, the conductor track 72 is primarily located directly beneath the contact surfaces 27, separated from them only by a layer that is as thin as possible, electrically insulating, but thermally conductive.

[0299] At the in Fig. In the example shown in Figure 6, the conductor track 72 has a narrow, meandering section 73 directly below each contact surface 27. This section has a small cross-section and high electrical resistance. The narrow, meandering sections 73 serve as heating elements. In sections between the contact surfaces 27, the conductor track 72 has a greater width and thus lower electrical resistance per unit length.

[0300] The narrow and meandering areas 73 of the conductor track 72 below the contact surfaces 27 can – as in Fig. 6 indicated - electrically connected in series. Alternatively, the narrow and meandering sections 73 of the conductor track 72 can be connected in parallel in groups. Alternatively, all narrow and meandering sections 73 of the conductor track 72 can be connected in parallel.

[0301] The supply of electrical power to the devices based on the Fig. 2 and Fig. 3 heating resistors 71 shown or to the one based on the Fig. 4 and Fig. 5 electrically conductive adhesive 62 shown on the one hand and the supply of electrical power, to which the Fig. The operation of the conductor track 72 shown in Figure 6 can be simultaneous or sequential. For simultaneous electrical power supply, the heating resistors 71 or the electrically conductive adhesive 62, on the one hand, and the conductor track 72, on the other hand, can be connected electrically in series or in parallel. In this case, the electrical power supply can also deviate from the illustration shown in Figure 6. Fig. 2 to 6 via the same electrically conductive components.

[0302] Fig. Figure 7 shows a schematic representation of an embodiment of the mechanical connection between the outer shaft 30 and the handling device 40 of the medical instrument 10. Fig. 1 and simultaneously an embodiment of the proximal contacting of the electrically conductive transmission devices 33 (see Fig. 2 to 5).

[0303] A proximal end region 38 of the outer shaft 30 and a distal end region 41 of the handling device 40 are each shown in section along a plane containing the longitudinal and symmetry axis of the outer shaft 30. The handling device 40 is shown in Fig. 7 is represented in particular by its housing. A user interface in the form of one or more wheels, levers, buttons or other manually operated devices on the outside of the handling device 40 and most of the devices inside the handling device 40 are not shown.

[0304] A recess 42 is provided at the distal end 41 of the handling device 40, in which the proximal end 38 of the outer shaft 30 is arranged. A bimetallic component 63, shaped like an almost complete ring (i.e., C-shaped with a small gap between the ends), is arranged within the proximal end 38 of the outer shaft 30. The component 63 rests against the inner surface of the proximal end 38 of the outer shaft 30. At room temperature, the component 63 presses the proximal end 38 of the outer shaft 30 outwards against the inner surface of the recess 42 in the handling device 40. This creates a force-fit or friction-fit mechanical connection between the proximal end 38 of the outer shaft 30 and the distal end 41 of the handling device 40.

[0305] Heating resistors 71 are arranged near component 63. When electrical power is supplied to the heating resistors 71, they and their surroundings, and thus also the bimetallic component 63, are heated. Component 63 is designed such that it shrinks when heated, i.e., its circumference and diameter decrease, or the radially outward pressing force exerted by component 63 on the proximal end region 38 of the outer shaft 30 decreases. Upon sufficient heating, the force-fit or friction-fit connection between the proximal end region 38 of the outer shaft 30 and the distal end region 41 of the handling device 40 is lost, and the outer shaft 30 and handling device 40 can be separated.

[0306] The heating resistors 71, together with the bimetallic component 63, act as a release device to weaken or loosen the mechanical connection between the outer shaft 30 and the handling device 40. The weakening of the mechanical connection by heating the bimetallic component 63 is limited, and the static friction remains high enough, that the shaft 13 and the handling device 40 cannot be easily separated, especially not solely due to the acting weight forces, but can be separated by a separating force that can be easily generated manually.

[0307] Contrary to the representation in Fig. 7 can be done similarly to the ones based on the Fig. In embodiments 2 to 5, a compressed helical spring or another elastic device may additionally be provided as a separating device. This separating device then pushes the outer shaft 30 away from the handling device 40 as soon as the mechanical connection between the two is sufficiently released by the release device 71, 63.

[0308] Contrary to the representation in Fig. Furthermore, the bimetallic component 63 itself can be designed as a heating element if its electrical resistance is suitable to produce sufficient heating through current flow. In this case, no separate heating resistors 71 are provided; instead, for example, the ends of the C-shaped component are contacted.

[0309] Component 63 can be made of a shape-memory material with a suitable transformation temperature instead of bimetal. In this case, one or more separate heating resistors can also be provided, or component 63 itself can be contacted to be heated by an electric current.

[0310] Furthermore, a wheel 43 is provided in the handling device 40, to which the proximal ends of the transmission devices 33 (see Fig. 2 to 5) are attached. Wheel 43 is mechanically coupled to a Fig. 7. Manually operated device not shown, for example a wheel or a lever on the outside of the handling device 40. Alternatively, the wheel 43 can be driven by a motor.

[0311] A rotation of the wheel 43 is accompanied by a distal movement of one transmission device 33 and a proximal movement of the other transmission device 33. These movements have the effect of the in Fig. 2. The distal end component 20 of the shaft 13 pivots, indicated by a dashed contour. To allow pivoting of the distal end component 20 about two orthogonal axes, the following may be used, deviating from the illustration in Fig. 7 Three, four or more transmission devices 33 may be provided. Their proximal ends can be moved by means of two wheels or by more complex devices.

[0312] As shown by the Fig. 2 and Fig. As shown in Figure 3, the transmission devices 33 can be electrically conductive and, in addition to their mechanical function, can be designed to transmit electrical power to the heating resistors 71. Fig. Figure 7 shows an embodiment of an electrical contacting of the transmission devices 33 in the handling device 40.

[0313] Each of the transmission devices 33 is provided with a sliding contact 45. Each sliding contact 45 is pressed against the associated transmission device 33 by an elastic device (not shown). The sliding contacts 45 have, for example, a graphite or bronze surface, or a gold-plated surface. The sliding contacts 45 can simultaneously perform mechanical functions, such as generating a mechanical stress in the associated transmission device 33.

[0314] Alternatively and deviating from the representation in Fig. 7 The sliding contacts 45 can, for example, be in contact with electrically conductive areas of the wheel 43, each of which is electrically connected to only one of the two transmission devices 33.

[0315] Alternatively and deviating from the representation in Fig. 7. The transmission devices 33 can be guided in tubular or hose-shaped housings similar to Bowden cables. These housings are designed to be particularly pressure-resistant, meaning they are not or only minimally compressible in their longitudinal direction. These housings can, for example, be made of coiled wire with a rectangular cross-section. These housings can also conduct electrical current and transmit electrical power. For detachable contact, pressure contacts are provided on the outer surfaces of the housings.

[0316] Fig. Figure 8 shows a schematic representation of a further embodiment of the mechanical connection between the outer shaft 30 and the handling device 40 of the medical instrument 10. Fig. 1 and simultaneously a further embodiment of the proximal contacting of the electrically conductive transmission devices 33 (see Fig. 2 to 5). The type of presentation corresponds to that of the Fig. 7. The in Fig. The embodiment shown in section 8 is similar in some features, properties and functions to the one shown in the Fig. 7 illustrated embodiment.

[0317] The following are four key differences compared to the one based on the Fig. The exemplary embodiment shown in section 7 is described, which is largely independent of each other and is based on the features of the Fig. 7 can be combined in the illustrated embodiment.

[0318] As with the one based on the Fig. In the embodiment shown in Figure 7, a recess 42 is provided in the distal end region 41 of the handling device 40, in which the proximal end region 38 of the outer shaft 30 is arranged. In the embodiment shown in Figure 7, a recess 42 is provided in the distal end region 41 of the handling device 40, in which the proximal end region 38 of the outer shaft 30 is arranged. Fig. In the embodiment of the mechanical connection shown in Figure 8, the handling device 40 has several pawls, locking lugs, or barbs 64 on flexible webs 65 that engage in corresponding recesses on the inside of the proximal end region 38 of the outer shaft 30. When the proximal end region 38 of the outer shaft 30 is inserted into the recess 42 in the handling device 40, the pawls 64 can be deflected against an elastic restoring force of the webs 65. As soon as the proximal end region 38 of the outer shaft 30 is fully inserted into the recess 42 in the handling device 40, the pawls 64 are pressed into the recesses on the inside of the outer shaft 30 by the elastic restoring force of the webs 65. The latches 64 thus engage in the corresponding recesses in the proximal end region 38 of the outer shaft 30.From this point on, the latches 64 form a positive locking connection between the handling device 40 and the outer shaft 30.

[0319] Heating resistors 71 are arranged near the pawls 64 and the ridges 65 and are thus thermally coupled to them. The pawls 64 and the ridges 65 can be heated by means of the heating resistors 71. The pawls 64 and the ridges 65 are made of a material that softens or melts within a predetermined temperature range above room temperature, for example, a thermoplastic. By supplying sufficient electrical power to the heating resistors 71, the pawls 64 and the ridges 65 can be heated to such an extent that they melt or soften to such an extent that they no longer hold the outer shaft 30 and the handling device 40 together, or only weakly. The heating resistors 71 thus act as a release device to weaken or loosen the mechanical connection between the outer shaft 30 and the handling device 40.

[0320] The weakening of the mechanical connection due to the heating and softening of the pawls 64 and bridges 65 goes in particular only so far that the shaft 13 and handling device 40 are not yet easily separated, in particular not solely due to the acting weight forces, but can be separated by a separating force that can be easily generated manually.

[0321] Instead of individual latches 64 and web 65, a ring-shaped latch can be provided on a cylindrical web, resulting in the same cross-sectional appearance. The ring-shaped latch then engages in a similarly ring-shaped groove on the inside of the proximal end region 38 of the outer shaft 30.

[0322] Contrary to the representation in Fig. 8 Furthermore, in this embodiment, a pre-tensioned helical spring or other elastic device can also be provided as a separating device between the proximal end region 38 of the outer shaft 30 and the distal end region 41 of the handling device.

[0323] Another difference of the in Fig. 8 shown embodiment, which is based on the Fig. The feature shown in Figure 7 consists in the fact that a flexible conductor 46 is provided for each of the transmission devices 33, for example as in Fig. 8 indicated in the form of a spiral spring. Each flexible conductor 46 can simultaneously perform a mechanical function, for example, centering the pivotable distal end component 20 in a central orientation by means of its elastic restoring force. Alternatively and deviating from the illustration in Fig. 8 The flexible conductors 46 can, for example, be connected to each electrically conductive area of ​​the wheel 43, wherein each electrically conductive area of ​​the wheel 43 is only electrically connected to one of the two transmission devices 33.

[0324] Another difference of the in Fig. 8 shown embodiment, which is based on the Fig. The difference shown in Figure 7 is that the manually rotatable wheel 42 is only designed to be wheel-shaped to the extent necessary. In the example shown, the wheel 42 can be rotated approximately a quarter turn, i.e., 90 degrees. Therefore, the arc-shaped sections on which the transmission devices 33 can rest each encompass only slightly more than 90 degrees.

[0325] Contrary to the representations based on the Fig. 7 and Fig. 8 Instead of a complete or incomplete wheel 43, only a lever may be provided, at the ends of which the proximal ends of the transmission devices 33 are attached.

[0326] Another difference of the in Fig. 8 shown embodiment, which is based on the Fig. The mechanism shown in Figure 7 consists in the fact that the anchoring of the proximal ends of the transmission devices 33 to the wheel 43 can be thermally weakened or loosened. For this purpose, the wheel 43, for example, comprises a thermoplastic or other material that melts at a predetermined temperature or softens to such an extent that the proximal ends of the transmission devices 33 are released. In the case described in Fig. In the embodiment shown in Figure 8, two further heating resistors 71 are arranged near and at the anchorages of the proximal ends of the transmission devices 33 in the wheel 43. When a predetermined electrical power is supplied to the heating resistors 71, the fastenings of the proximal ends of the transmission devices 33 in the wheel 43 are heated to such an extent that the mechanical connection between them is released. This can be facilitated by the fact that the transmission devices 33 are under mechanical tension.

[0327] Mechanical connections, release devices and disconnect devices, as described in the Fig. The connections described in sections 1 to 5 for the connection between a distal end component 20 and an outer shaft 30 are similarly possible for the connection between the outer shaft 30 and the handling device 40, as well as for the connection between the handling device 40 and the cable 50, for the connection between the cable 50 and the connector 57, and for other connections between components of medical instruments. Mechanical connections, release devices, and disconnect devices, as described in the Fig. 7 and Fig. 8 for the connection between outer shaft 30 and handling device 40, similar connections are also possible for the connection between a distal end component 20 and an outer shaft 30, as well as for the connection between handling device 40 and cable 50, for the connection between cable 50 and connector 57 and for other connections between components of medical instruments.

[0328] Fig. Figure 9 shows a schematic representation of a medical system consisting of a heated hose set 90 as a further example of a medical instrument and an associated supply unit 100.

[0329] The heated tubing set 90 includes a tube 91 for delivering fluid to a patient. The tube 91 is designed and configured to be connected to a trocar tube or other device intended to be at least partially inserted into a patient's body and to create artificial access to a natural or artificial cavity in the body.

[0330] The heated hose set 90 further comprises a branch 92 and a fluidic connector 93. The branch creates a fluidic connection between the fluidic connector 93 and a proximal end of the hose 91. The fluidic connector 93 is designed and configured to be fluidically coupled to a corresponding connector of the supply unit 100, in particular as shown in Fig. 9 indicated, immediately.

[0331] The heated hose set 90 further comprises a heating wire 94 which is arranged in the lumen of the hose 91. This differs from the illustration in Fig. 9 The heating wire 94 can be arranged in the wall of the hose 91. Heat can be supplied to a fluid flowing in the hose 91 by means of the heating wire 94. This can, in particular, compensate for heat loss through the wall of the hose 91 to the surroundings.

[0332] The heated hose set 90 also includes an electrical cable 50. An electrical connector 57 is provided at a proximal end of the cable 50. The electrical connector 57 of the heated hose set 90 is designed and configured for mechanical and electrical connection with a corresponding connector 107 of the power supply unit 100. The splitter 92 forms a mechanical connection between the distal end of the electrical cable 50 and the proximal end of the hose 91. Furthermore, the splitter 92 provides an electrical connection between the electrical cable 50 and the heating wire 94.

[0333] The supply unit 100 includes a device 103 for conveying or supplying a fluid, for example, a pump or a blower. Alternatively or additionally, the device 103 may include one or more cascaded pressure-reducing valves for reducing the high gas pressure from a gas cylinder or from a gas supply network of a hospital or other medical facility. The supply unit 100 allows, in particular, the setting of a setpoint and the control of the pressure, mass flow rate, volumetric flow rate, and / or composition (especially the moisture content) of the fluid flow supplied by the device 103. Fluid supplied by the supply unit 100 flows through the fluidic connector 93, the branch 92, and the hose 91 to exit at its distal end.

[0334] The supply unit 100 includes, in addition to the device 103 for conveying a fluid, a first power source 102 for providing electrical power for the heating wire 94, and a second power source 106 for providing electrical power for a [missing information]. Fig. 9 not shown dissolving device and a control 108 for controlling the device 103 for conveying, the first power source 102 and the second power source 106.

[0335] The supply unit 100 also has a user interface 110. At the user interface 110, a person using the medical system consisting of the heated tubing set 90 and the supply unit 100 can adjust operating parameters, in particular the properties of the fluid flowing through the tubing set. These properties include the temperature of the fluid, which is influenced by the heating wire 94.

[0336] Furthermore, the end of the intended use of the heated hose set 90 can be indicated at the user interface 110 by means of a user input. The controller 108 then controls the supply of electrical power by the second power source 106 for the aforementioned release device of the heated hose set.

[0337] Fig. Figure 10 shows a schematic and enlarged view of a section through the proximal end of the hose 91, the branch 92 and the fluidic connector 93 of the heated hose set 90. Fig. 9. The cutting plane of the Fig. Figure 10 contains the axes of symmetry of the hose 91 and the fluidic connector 93.

[0338] The connection of the proximal end of hose 91 to the branch 92 is made at the point shown in Fig. In the example shown in Figure 10, the branch 92 is secured by inwardly projecting latches, locking lugs, or barbs 66, which engage from the outside in corresponding recesses in the proximal end of the hose 91 or simply dig into the flexible material of the hose 91. While the shape of the latches, locking lugs, or barbs 66 allows the proximal end of the hose 91 to be inserted into the branch 92, the locking lugs or barbs 66 offer considerable resistance to separating the hose 91 from the branch 92. This resistance is not overcome by the forces occurring during the intended use of the heated hose set 90.

[0339] In the illustrated example, the mechanical connection between the branch 92 and the fluidic connector 93 is also formed by latches, locking lugs, or barbs 67, which, however, are provided on the fluidic connector 93 and engage in corresponding recesses in the branch 92. The shape of the latches, locking lugs, or barbs 67 allows the distal end of the fluidic connector 93 to be inserted into the branch 92. However, the locking lugs 67 offer considerable resistance to the separation of the fluidic connector 93 from the branch 92, resistance which is not overcome by the forces occurring during the intended use of the heated hose set 90.

[0340] In the branch 92, heating resistors 71 are provided near the locking lugs or barbs 66 and near the locking lugs 67 for local heating of the branch 92. Fig. Figure 10 indicates the heating resistors as coaxial windings of a resistance wire, respectively, to the lumen of the hose 91 and to the distal end of the fluidic connector 93. These windings are recognizable as series of cross-sections through the resistance wire. To optimize heat transfer, the heating resistors 71 are directly embedded in the material of the splitter 92.

[0341] When the second power source 106 of the supply unit 100 provides sufficient power for the heating resistors 71, the material of the splitter 92 melts or softens. This weakens or loosens the mechanical connection between the splitter 92 and the hose 91, and the mechanical connection between the splitter 92 and the fluidic connector 93, allowing them to be manually disconnected. The heating resistors 71 thus act as disconnecting devices.

[0342] The weakening of the mechanical connection due to the heating of the branch 92 and the locking lugs 66, 67 goes in particular only so far that the hose 91 and the connector 93 are not yet easily separated from the branch 92, in particular not solely due to the acting weight forces, but can be separated by separating forces that can be easily generated manually.

[0343] Alternatively and deviating from the representation in Fig. 10 One or more prestressed elastic devices can be provided as separating devices which, after melting or softening of the branch 92 or the latches 66, 67, separate the proximal ends of the hose 91 or the fluidic connector 93 from the branch 92.

[0344] Fig. Figure 11 shows a schematic and enlarged representation of an embodiment of the connector 57 at the proximal end region 55 of the cable 50 and of the corresponding connector 107 of the supply unit 100. Fig. 1 or off Fig. 9. Cable 50 and connectors 57 and 107 are shown in a longitudinal section. The mechanical connection between cable 50 and connector 57 can be visualized similarly to the... Fig. 1 to 5 and 7 to 10 are depicted and are in Fig. Figure 11 is not shown in detail. Connectors 57 and 107 are shown spatially separated from each other, but oriented in such a way that they can be mechanically and electrically connected to each other by a simple straight-line movement.

[0345] The connector 57 at the proximal end region 55 of the cable 50 has contact pins 58. The connector 107 of the power supply unit 100 has corresponding contact sockets 118 in a corresponding number and arrangement for the contact pins 58.

[0346] At least two of the contact pins 58 and two corresponding contact sockets 118 are for transmitting electrical power from the supply unit 100 to a release device 71, 73 of the medical instrument 10 (see Fig. 1 to 10). These contact pins 58 and contact sockets 118 can be used both for transmitting signals and / or electrical power for the functions required during the intended use and for transmitting electrical power to the release device or release devices 71, 73 of the medical instrument 10. During the intended use of the medical instrument 10, all contact pins 58 and contact sockets 118 transmit signals and / or electrical power for the functions required during the intended use between the power supply unit 100 and the medical instrument 10. After the intended use of the medical instrument 10 has ended, at least two contact pins 58 and two corresponding contact sockets 118 transmit electrical power to the release device or release devices 71, 73 of the medical instrument 10.The electrical power provided for the release device or release devices 71, 73 may differ from the electrical power and signals provided during the intended use in voltage level, polarity, current, and frequency.

[0347] The connector 107 of the power supply unit 100 has several contact sockets 118. The contact sockets 118 of the connector 107 of the power supply unit 100 are arranged correspondingly to the contact pins 58 of the connector at the proximal end region 55 of the cable 50.

[0348] Connector 57 has one or, as in Fig. Figure 11 indicates several lateral recesses 120. The recesses 120 are arranged in an area which, when the connector 57 is connected to the connector 107 of the supply unit 100, lies within the volume enclosed by the connector 107 of the supply unit 100.

[0349] Several locking bars 122 are provided on the connector 107 of the power supply unit 100. Each locking bar 122 on the connector 107 of the power supply unit 100 is arranged corresponding to a recess 120 on the connector 57 at the proximal end region 55 of the cable 50. Each locking bar 122 is movable along a short predetermined path in its longitudinal direction orthogonal to the insertion direction of the connectors 57, 107. Each locking bar 122 is held in place by the elastic restoring force of a Fig. 11 not shown prestressed elastic device in the in Fig. The position shown in Figure 11 is maintained. Each locking bar 122 can be moved completely or largely out of the volume enclosed by the connector 107 of the supply unit 100 against this elastic recoil force.

[0350] Each bar 122 is equipped with a drive 124, in Fig. Figure 11 is shown as an example of coils. These drives 124 are coupled to the control unit 108. The control unit 108 can use the drives 124 to move the latches 122 out of the volume enclosed by the connector 107 of the supply unit 100, in order to disconnect the mechanical and electrical connection of the connectors 57, 107.

[0351] When the connector 57 is connected to the connector 107 of the power supply unit 100 at the proximal end region 55 of the cable 50 in the intended manner, the contact pins 58 engage in the contact sockets 118, thereby establishing electrical connections and, due to positive locking and static friction, a mechanical connection. This connection can also be released again against the static friction between the contact pins 58 and the contact sockets 118.

[0352] When the locking bars 122 on the connector 107 of the power supply unit 100 engage in the recesses 120 on the connector 57 at the proximal end 55 of the cable 50, the connectors 57 and 107 are mechanically locked. The control unit 108 can release this lock by actuating the drives 124, after which the connectors 57 and 107 can be separated against the frictional force between the contact pins 58 and the contact sockets 118.

[0353] Fig. Figure 12 shows a schematic and enlarged representation of a further embodiment of the connector 57 at the proximal end region 55 of the cable 50 and of the corresponding connector 107 of the supply unit 100. Fig. 1 or off Fig. 9. The style of presentation is similar to that of Fig. 11. The in Fig. The embodiment shown in 12 is similar in some features, properties and functions to the one shown in the Fig. 11 illustrated embodiment.

[0354] The following are, in particular, differences compared to the one based on the Fig. 11 described in the illustrated embodiment.

[0355] At the in Fig. In the embodiment shown in Figure 12, both connectors 57, 107 have essentially flat end faces.

[0356] The connector 57 at the distal end region 55 of the cable 50 has a or -as in Fig. 12 indicated - several permanent magnets 130. The connector 107 has several electromagnets 132 arranged corresponding to the permanent magnets 130, which are controlled by the control unit 108 of the power supply unit 100. An attractive magnetic interaction between the electromagnets 132 and the permanent magnets 130 creates a connection between the connectors 57, 107. With sufficient dimensioning of the permanent magnets 130 and the electromagnets 132 and a sufficiently high current, a very high holding force can be achieved. The connectors 57, 107 are then connected to each other in a manner that is determined based on the Fig. Since the positive locking mechanism shown in Figure 11 is equivalent to a magnetic locking mechanism, it is a magnetic locking mechanism.

[0357] A further difference, independent of this magnetic locking mechanism but advantageously combinable with it, from the one based on the Fig. The embodiment shown in Figure 11 consists in the design of the electrical contacts 134, 136 on the connectors 57, 107. In the embodiment shown in Fig. In the embodiment shown in Figure 12, the electrical contacts 134, 136 protrude only slightly beyond the end faces of the connectors 57, 107. The electrical contacts 134 on the connector 57 at the proximal end region 55 of the cable 50 are designed as spring-loaded contact pins that protrude only slightly (a few millimeters or less). This design is also known as pogo pins. The electrical contacts 136 on the connector 107 at the power supply unit 100 are designed as flush contact surfaces within an otherwise electrically insulating surface area.

[0358] Fig. Figure 13 shows a schematic and enlarged representation of an embodiment of a disposal device 200 for the disassembled disposal of a medical instrument, for example an endoscope 10, as shown by the Fig. 1 to 8 is shown, or a heated hose set 90, as shown by the Fig. 9 and Fig. Figure 10 is shown. However, the disposal device 200 is also suitable for the disassembled disposal of other medical instruments with disassembly devices 71, 73, 81.

[0359] The disposal device 200 has several containers 210, each with an inlet opening 212. Only one of the containers 210 is marked with a reference symbol. Components of medical instruments can be inserted into the containers 210 through the inlet openings 212. The containers 210 are specifically designed for different components. By assigning and distributing components into different containers 210, sorting and separation according to material or with regard to subsequent processing steps can be carried out.

[0360] Each container 210 can have its own contour mask 214 at the inlet opening 212. Each contour mask 214 can indicate which component the container 210 is intended for, or even obstruct or prevent the passage of another component.

[0361] In the example shown, the contour mask 214 is funnel-shaped to simplify the insertion of the component intended for the container 210.

[0362] The disposal device 200 further comprises a level sensor 216 on each container 210. The level sensor 216 detects the fill level and generates a sensor signal that represents the detected fill level or indicates that a predetermined fill level has been exceeded.

[0363] The disposal device 200 further comprises a power source 220 for providing power to a disassembly device for a medical instrument and an interface 227. The interface 227 is connected to the power source 220 and is compatible with an interface of a medical instrument 10 to be disassembled and disposed of. For example, the interface 227 is a connector and corresponds to one of the connectors defined by the Fig. 11 or Fig. 12 connectors 107 of a power supply unit 100 shown.

[0364] Power provided by power source 220 can be transferred via interface 227 to a corresponding interface of the medical instrument to be dismantled and disposed of, and supplied to the dismantling device of the medical instrument. A medical instrument that is not already supplied by a power supply unit 100 (see below) after completion of its intended use. Fig. 1, Fig. 9) has been provided, has been dismantled, can be dismantled using the power provided by the disposal device 200.

[0365] The disposal device 200 further comprises a sensor 230 for identifying a medical instrument or its type. The sensor 230 includes, for example, an RFID reader for reading an RFID transponder on a medical instrument. Alternatively or additionally, the sensor 230 may include a camera or scanner for capturing a one- or multi-dimensional optical code (in particular barcode, QR code, matrix code, dot code, etc.) on a medical instrument 10. Alternatively or additionally, the sensor 230 may include a camera, wherein a medical instrument or its type is identified by means of an image evaluation or image recognition device based on one or more images of the medical instrument captured by the camera.

[0366] The disposal device 200 further comprises a controller 240, which is coupled to the sensor 230 to receive a signal from the sensor 230 that identifies the medical instrument or its type. If the sensor 230 includes a camera, image evaluation or image recognition – as a hardware and / or software component – ​​can be partially or fully integrated into the controller 240.

[0367] The disposal device 200 further comprises a screen 242 as an output device. The screen 242 is controlled by the controller 240 by means of a video signal. Alternatively or additionally, the disposal device 200 may include an interface for a screen or other video output device, a loudspeaker or an interface for a loudspeaker, headphones or other audio output device.

[0368] The disposal device 200 further comprises a signaling device 244 at the inlet opening 212 of each container 210. The signaling device 244 generates, for example, a simple light signal, which indicates by its color or a temporal modulation, whether a component of a medical instrument 10 is to be placed in the associated container 210 or not. Alternatively, the signaling device 244 may, for example, comprise an alphanumeric display or a screen. The signaling devices 244 are coupled to and controlled by the controller 240.

[0369] As an alternative to contour mask 214, or as in Fig. As indicated in Figure 13, in addition to this, a controllable barrier device 246 can also be provided at the inlet opening 212 of each container 210. The barrier device 246 is shown by way of example as a motor-operated closing flap that can close or open the associated inlet opening 212. The barrier devices 246 are coupled to and controlled by the control unit 250.

[0370] The disposal device 200 further comprises a transmitter 250 for sending a signal to a service provider. The transmitter 250 is specifically designed to send a fill level signal representing the fill levels of the containers 210 or indicating that a predetermined fill level has been exceeded. The transmitter 250 is specifically configured to transmit the fill level signal via an Ethernet cable or WLAN. The transmitter 250 is coupled to and controlled by the controller 240.

[0371] The disposal device 200 further comprises a treatment unit 260 for treating a component. The treatment unit 260 is arranged between an inlet opening 212 and the associated container 210. The treatment unit 260 can be arranged partially or completely inside the container 210. The treatment unit 260 can be configured for crushing (chopping, shredding, grinding, tearing, cutting), folding, compressing, or melting components. The treatment unit 260 is coupled to and controlled by the control unit 240.

[0372] The disposal device 200 further comprises a feed device 270 for supplying water or another liquid to a container 210. The feed device 270 includes, in particular, a valve for controlling the supply of water from a fresh water line of a building in which the disposal device 200 is located. The feed device 270 is coupled to and controlled by the control unit 240.

[0373] The disposal device 200 further comprises a storage container 272 for a gelling agent and a feeding device 274 for feeding water and gelling agent from the storage container 272 to a container 210. The storage container 272 may alternatively or additionally contain a disinfectant and / or a solvent for dissolving at least one material of the associated components. The feeding device 274 includes, for example, a pump for conveying the gelling agent (or the disinfectant or the solvent). The feeding device 274 is coupled to and controlled by the control unit 240.

[0374] The disposal device 200 further comprises a mixing device 276. The mixing device 276 is arranged in a container 210 and is designed to mix the contents of the container 210. The mixing device 276 is, in particular, arranged in the same container 210 to which the feed device 272 is also attached. The mixing device 276 is coupled to and controlled by the control unit 240.

[0375] Several containers 210 can each be equipped with their own feeding devices 270, 274 and a mixing device 276. Whether feeding water and gelling agent (and / or disinfectant and / or solvent) to a container and mixing its contents with water and gelling agent (and / or disinfectant or solvent) is necessary or advantageous depends on the components associated with the container 210, in particular on the materials, geometry, and function of the components and their typical contamination during the intended use. Therefore, feeding devices 270, 274, and a mixing device 276 can each be provided on one or more containers 210, while no feeding device or mixing device is provided on one or more other containers 210.Different mixtures of water, gelling agent and / or disinfectant and / or solvent can be added to different containers 210.

[0376] Alternatively and deviating from the representation in Fig. 13. The disposal device 200 may also have a wastewater connection for discharging wastewater into a building's wastewater system and subsequently into a wastewater treatment plant or the public sewer system. In this case, the disposal device 200 may be designed and configured for rinsing, washing, and cleaning all components, or at least components of predetermined types. The mixing device 276 is then specifically designed and configured for mixing components, rinse water, and cleaning agents.

[0377] Furthermore, the disposal device 200 may differ from the illustration in Fig. 13. Have a drying device for drying rinsed or washed components before storage.

[0378] A medical instrument to be dismantled and disposed of is first identified using sensor 230, primarily by recording the type of medical instrument. Optionally, the medical instrument can be further or fully identified by, for example, also recording the batch from which it originates or its serial number.

[0379] The medical instrument can be detected automatically by sensor 230 as soon as it is near the disposal device 200. Alternatively, the medical instrument can be detected as soon as it is placed on a predetermined and marked storage area. The sensor includes, for example, a camera that captures an image of the storage area.

[0380] Alternatively, the detection of the medical instrument by sensor 230 can be triggered by an input at a user interface. Alternatively, sensor 230 can be coupled with interface 227 to detect the identity or type of the medical instrument once a corresponding interface of the medical instrument is coupled with interface 227 of the disposal device 200.

[0381] The controller 240 controls or supports the subsequent disassembly and disposal of the medical instrument 10, depending particularly on the type of medical instrument. Different, individually adapted disassembly and disposal processes are supported for different types of medical instruments. The controller 240 can monitor the progress of the disassembly process—particularly through the sensor 230 and / or by querying a user interface—and support the next step depending on the progress. The sensor 230 also allows the controller 240 to detect the type of an individual component already separated from the rest of the medical instrument and, depending on the component type, support or control the next step.

[0382] On screen 242, disassembly and disposal steps are described using moving or static images, drawings, pictograms, and / or text to assist a person in disassembling and disposing of the medical instrument. Disassembly can be supported by providing power from power source 220 at interface 227, or it can be performed similarly to how described above. Fig. 2 to 10 are described. Before that, the controller 240 can request the connection of an interface of the medical instrument to the interface 227 of the disposal device 200.

[0383] If a separate component is present that cannot be further disassembled but is to be fed as such into a predetermined container 210, the controller 240 can mark the inlet 212 to the predetermined container by means of the signaling device 244 and release it by means of the controllable barrier device 246. As soon as the component has been fed into the container 210, the controller 240 can control treatment by the treatment device 260 and / or the supply of water, gelling agent, disinfectant and / or solvent by the supply device 272.

[0384] Once water and gelling agent and / or a disinfectant have been added, the controller 240 can control the mixing of the contents of the container 210 for an initial predetermined period, during which uniform mixing is expected. The controller 240 can then interrupt the mixing for a rest period with a second predetermined period, during which gelation is expected. Afterward, the controller 240 can reactivate the mixing device 276, monitoring the achieved rotational speed, impedance, current, or power consumption, and thus the mechanical resistance opposing the mixing process. If the resistance exceeds a predetermined value, gelation has progressed sufficiently.

[0385] The controller 240 can use the level sensors 216 to detect the fill levels of the containers 210. When a container 210 reaches or exceeds a predetermined fill level, the transmitter can, for example via LAN or WLAN and the internet, notify a service provider who will collect the container 210 for disposal.

[0386] The Fig. 14 and Fig. Figure 15 shows two parts of a schematic flowchart of a procedure for preparing a medical instrument 10, 90 for use, for using the medical instrument 10, 90, and for disassembling and disposing of the medical instrument 10, 90 after intended use. The procedure is particularly applicable to medical instruments 10, 90 such as those described in the Fig. 1 to 11 are shown, supply units 100, as shown based on the Fig. 1 and Fig. 9 are shown, and a disposal device 200, as shown on the Fig. As shown in section 13, this is feasible. Therefore, reference symbols from the following are used as examples. Fig. 1 to 13 are used, although the procedure can also be carried out with medical instruments, supply units and disposal devices, which are not shown in the illustrations. Fig. exhibit 1 to 13 different characteristics, properties and functions.

[0387] In a first step 301, a mechanical and electrical and / or optical connection is established between an interface 57 – in particular a connector – of a medical instrument 10 and a corresponding interface 107 of a power supply unit 100. In a second step 302, the mechanical connection is locked, in particular by means of one or more latches 122, which prevent separation of the interfaces 57 and 107 by means of a positive locking mechanism. Alternatively, the mechanical connection is established magnetically, whereby a magnetic holding force is generated that is difficult to overcome, which is equivalent to a conventional positive locking mechanism.

[0388] Step 301 and step 302 constitute a procedure for preparing the use of the medical instrument 10, 90. This does not yet include the use of the medical instrument 10, 90 or the medical system consisting of the medical instrument 10, 90 and the supply unit 100 itself. No interaction with a patient's body takes place at this stage.

[0389] In a subsequent step 303, the medical system consisting of the medical instruments 10, 90 and the supply unit 100 is used as part of a medical procedure.

[0390] All subsequent steps take place after the medical procedure and again without any interaction with the patient's body. In particular, no part of the medical instrument 10, 90 is located inside or near the patient's body.

[0391] In step 311, the supply unit 100 receives a user input indicating the end of the use of the medical instrument 10, 90. The user input is entered, in particular, at a user interface 110 of the supply unit. This user input simultaneously confirms that the medical instrument 10, 90 has been removed from the surgical site, meaning that it no longer interacts with the patient's body; rather, the medical instrument has been removed from the body.

[0392] In a subsequent step 312, power is provided for a disassembly device, in particular for one or more disassembly devices 71, 73 of the medical instrument 10, 90. The power is provided in particular by the supply unit 100.

[0393] In an optional step 313, the provided power can be transferred by conducting an electric current through a transmission device 33.

[0394] In step 314, a connection point 61, 62, 63, 64, 65, 66, 67 is heated, and in step 315, the connection point 61, 62, 63, 64, 65, 66, 67 is loosened by heating. Alternatively, the supplied power loosens the mechanical connection in another way.

[0395] Steps 312, 313, 314, and 315 occur simultaneously or almost simultaneously. In particular, the provided power is simultaneously transmitted by passing a current through the transmission device 33, and the transmitted power heats the connection point, thereby releasing the mechanical connection with a slight time delay.

[0396] Using the provided power, several mechanical connections 61, 62, 63, 64, 65, 66, 67 between two or more components 20, 24, 25, 30, 40, 50, 91, 92, 93 can be loosened simultaneously or sequentially.

[0397] The mechanical connections can be designed such that, after the mechanical connections 61, 62, 63, 64, 65, 66, 67 are released, elastic restoring forces of prestressed components 33, 81, for example, cause the components 20, 24, 25, 30, 40, 50, 91, 92, 93 to separate. Alternatively, the separation of the components 20, 24, 25, 30, 40, 50, 91, 92, 93 can be carried out manually or by other means.

[0398] At step 316, a success signal is received, indicating that the mechanical connection of components 20, 24, 25, 30, 40, 50, 91, 92, 93 has been successfully released. The success signal is, or represents, for example, the electrical resistance of a heating element or circuit, which is inevitably interrupted when the components are separated.

[0399] In step 317, the mechanical connection between interface 57 of the medical instrument 10, 90 and the corresponding interface 107 of the supply unit 100 is unlocked. By not unlocking the mechanical connection of interfaces 57, 107 immediately after the intended use of the medical instrument 10, 90 in a medical procedure, but only after disassembly or at least the initiation of disassembly, it can be ensured that the medical instrument 10, 90 is not used a second time. This can improve patient safety.

[0400] At a Fig. In step 14 (not shown), several containers 210 are provided to hold various components of the medical instrument 10, 90. This step can be performed long before steps 301, 302, 303, 311, 312, 313, 314, 315, 316, 317.

[0401] In step 321, the identity of the medical instrument 10, 90 to be disposed of is recorded, in particular by means of a sensor 230. The containers 210 and the sensor 230 are in particular components of a disposal device 200 for the disassembled disposal of medical instruments 10, 90.

[0402] In step 322, an output device 242 is controlled to assist a person in disassembling the medical instrument 10, 90. This involves, in particular, presenting steps of disassembly and separate disposal in spoken or written text, in moving or still images, in drawings, with pictograms, or other visually or audibly perceptible signs. Step 322 may differ from the representation in Fig. 14 during the following procedure, each step is repeated, adapted to the progress of the disassembly, which is detected in particular by means of the sensor.

[0403] In step 331, an interface 57 of the medical instrument 10, 90 is coupled with a corresponding interface 227 of the disposal device 200. If step 331 differs from the representation in Fig. If step 14 is performed before step 321, the medical instrument 10, 90 or the type of medical instrument 10, 90 can be identified via interfaces 57, 227 instead of by sensor 230.

[0404] The following steps 332, 333, 334, and 335 correspond to steps 312, 313, 314, and 315, except that the power is provided not by a supply unit 100 but by the disposal device 200. Steps 312, 313, 314, and 315 at the supply unit 100, on the one hand, and steps 332, 333, 334, and 335 at the disposal device 200, on the other hand, represent alternatives. Only insofar as steps 312, 313, 314, and 315 at the supply unit 100 do not release all mechanical connections between components 20, 24, 25, 30, 40, 50, 91, 92, and 93 of a medical instrument 10, 90, are the remaining mechanical connections to be released in the steps. 332, 333, 334, 335 to be released. The separation of components 20, 24, 25, 30, 40, 50, 91, 92, 93 after releasing the mechanical connections can be carried out by elastic restoring forces of prestressed elastic components 81 or by other separating devices or manually.

[0405] In step 341, the type of a component 20, 24, 25, 30, 40, 50, 91, 92, 93 that is separated from other components 20, 24, 25, 30, 40, 50 is identified, in particular by sensor 230. This identification can occur automatically if sensor 230 – in particular in the form of a camera with downstream image recognition – automatically detects that a component 20, 24, 25, 30, 40, 50, 91, 92, 93 is separated from other components 20, 24, 25, 30, 40, 50, 91, 92, 93. Alternatively, step 341 can be triggered by input at a user interface or by a gesture. If sensor 230 includes a camera, a gesture can also be detected by sensor 230.

[0406] Fig. Figure 15 shows the continuation of the flowchart of the procedure from Fig. 14. Above is the last one again in Fig.14 illustrated steps 341 are shown, in which the type of a component 20, 24, 25, 30, 40, 50, 91, 92, 93, which is separated from other components 20, 24, 25, 30, 40, 50, 91, 92, 93, is identified.

[0407] Depending on the identified type of component 20, 24, 25, 30, 40, 50, the controller 240, in step 342, controls a signaling device 244 and / or, in step 343, a barrier device 246, to mark or release the inlet opening 212 to the container 210 intended for component 20, 24, 25, 30, 40, 50. Simultaneously, the inlet openings 212 to the other containers 210 can be marked as not to be used and / or blocked or closed. Alternatively or additionally, the controller 240 can, by means of the output device 242, provide an indication of the inlet opening 212 to the intended container 210.

[0408] In step 349, the component 20, 24, 25, 30, 40, 50, 91, 92, 93 is guided through the associated entry opening 212. This step is performed manually.

[0409] The following steps may be intended for one or more containers 210 and may not be intended for other containers 210.

[0410] In step 350, component 20, 24, 25, 30, 40, 50, 91, 92, 93 is treated by a treatment device 260 between inlet opening 212 and container 210, for example by being chopped, shredded, ground, torn into smaller pieces, cut or otherwise crushed, washed, dried, folded, compressed, or sterilized and / or melted by heating. Only after step 350 does component 20, 24, 25, 30, 40, 50, 91, 92, 93 enter container 210.

[0411] The following steps are carried out depending in particular on the fill level of container 210.

[0412] In step 351, water and gelling agent and / or disinfectant and / or solvent are added to container 210. Gelling agent, disinfectant, or solvent can be supplied from a storage container, for example, by means of a pump. Water can be taken directly from a fresh water supply and fed in via a valve.

[0413] In step 352, the contents of container 210 are mixed. The aim is, in particular, to achieve a uniform mixing of the (whole or crushed) components contained therein with the water and the gelling agent, or a complete wetting of components 20, 24, 25, 30, 40, 50, 91, 92, 93 with the disinfectant.

[0414] In step 353, the mechanical resistance opposing the mixing process is measured. This is done particularly after the addition of gelling agent to monitor the gelling progress.

[0415] In step 354, the mixing is interrupted for a predetermined period of time. If necessary, gelling can continue during this predetermined period.

[0416] After the predetermined time has elapsed, mixing is resumed at step 355, and the resistance to mixing is measured again at step 356. This verifies whether gelling is complete. If not, gelling agent can be added again as in step 351, and then steps 352, 353, 354, 355, and 356 can be repeated.

[0417] The mixing process ends at step 357. Step 357 occurs depending on the resistance opposing the mixing action.

[0418] In step 358, container 210 is sealed. Once the originally liquid portion of the container's contents has completely gelled, the hazard posed by the container's contents is significantly reduced. Leakage of infectious liquid components and the escape of sharp-edged objects are practically eliminated. Therefore, the requirements for the tightness of the container's seal are considerably reduced.

[0419] In step 359, the sealed container 210 is released for transport. Container 210 can then be picked up by a service provider. To simplify logistics, the service provider may have been informed of the upcoming pickup a foreseeable time before the container is sealed, depending on its fill level. 10.
