Description

[0001] The invention relates to a mobile operating device for a medical device, an operating system for a medical device with such a mobile operating device and a method for controlling a medical device.

[0002] Imaging systems are used in a wide variety of hospital environments today. Operating the device is particularly challenging in the operating room, as the system must be operated from within a sterile environment. This operation is further complicated by the fact that the user, who in many cases is the operating surgeon themselves, often requires both hands to work on the patient and therefore does not have a free hand to operate the device. Furthermore, there is often insufficient space, especially on the operating table, to mount the corresponding input devices, so they are placed away from the operating table, further complicating operation.

[0003] Currently, even in sterile areas, medical devices are mostly operated using touchscreens and buttons or joysticks, which require comparatively large amounts of space and often hinder clinical procedures. There are also approaches to optical gesture recognition systems and voice input concepts, but both are subject to numerous limitations and have therefore not yet been able to gain widespread acceptance in the operating room environment, not least due to the risk of misidentification.

[0004] DE 10 2005 052 903 B4 describes a foot switch for medical treatment or diagnostic devices. It is designed as an overshoe that is pulled over a normal shoe. The overshoe contains a force sensor that can be switched by shifting the weight of the foot, as well as a position and movement sensor that detects the position and movement of the overshoe relative to a contact surface and / or an evaluation unit located outside the overshoe.

[0005] DE 198 32 512 A1 describes a shoe used for the telemetric control of work tools using toe movements or heel pressure. For this purpose, piezo elements are provided in the shoe, which are subjected to compression via the preferred end phalanges of the big toe, cranially or caudally, or via the heels. A downstream electronic system with an antenna controls a receiver, which has an interface to the work tool.

[0006] DE 10 2013 209 280 A1 describes a device and a method for generating a control signal for controlling a work machine. The control signal is generated based on position signals containing information about the position and orientation of an operating element of the work machine or an operator of the work machine. The operating element can be a wearable operating element in the form of clothing equipped with sensors.

[0007] DE 10 2006 040 941 A1 describes a medical device and a method in which an adjustable device of the medical device is operated using a portable operating module. The operating configuration of the operating module is automatically adjusted depending on the relative spatial position of the adjustable device to the operating module.

[0008] It is an object of the present invention to improve the operation of medical devices, especially in sterile areas.

[0009] This object is achieved by an operating device according to claim 1 or by an operating system according to claim 8 or by a method according to claim 9. Advantageous embodiments of the invention are specified in the subclaims.

[0010] The advantages and embodiments explained below in connection with the operating device also apply mutatis mutandis to the operating system according to the invention and the method according to the invention and vice versa.

[0011] A core idea of ​​the invention is to design the mobile operating device as a wearable component of the user's clothing or equipment. The operating device according to the invention is characterized by being arranged directly on the user. Preferably, the operating device is designed such that it can be worn by the user in such a way that the operating device can be considered part of the user, in particular, it follows the user's movements.

[0012] In contrast to conventional, non-mobile control devices, the control device according to the invention is therefore always located in a position that allows direct operation by the user. The user neither has to move toward the control device nor search for it. It is always located in a location known to the user and thus expected by the user.

[0013] The mobile, portable control device is preferably designed to allow hands-free operation, meaning the user doesn't have to hold the mobile control device in their hands. The control device is portable and, for this purpose, preferably small and lightweight, so that it requires minimal space. Clinical procedures are therefore not disrupted.

[0014] The mobile control device preferably uses classic, but in any case less error-prone, input techniques, so that misidentifications and the associated risks are excluded.

[0015] The concept of the portable, mobile operating device proposed by the invention lays the foundation for simple, realizable operation of medical devices in a sterile environment. Such a flexible, sterile operation of medical devices is not yet known in the prior art.

[0016] The mobile operating device according to the invention is preferably designed as part of a human-machine interface of the medical device, thus representing, for example, a module of a multi-component human-machine interface. Other components of the human-machine interface can be, for example, conventional, non-sterile hand switches, foot switches, keyboards, touch-sensitive screens (touchscreens), or a computer mouse.

[0017] The mobile operating device is preferably designed such that it can be worn by the user in such a way that the operating element is located directly on the hand or foot and / or within immediate reach of the fingers or toes. In a preferred embodiment of the invention, the operating system comprises at least one shoe and the operating device is designed as part of the shoe. This is preferably a surgical shoe, i.e. a shoe typical for operating rooms, for example designed as clogs. The operating device can be permanently connected to the shoe. As an alternative to such an integrated solution, the operating device is detachably connected to the shoe, in particular in such a way that the operating device can be removed from the shoe. In this way, the shoe itself can be cleaned and / or sterilized without the operating device orthe electrical / electronic components of the control device must undergo this procedure.

[0018] The use of the mobile control device in a shoe is particularly advantageous when a foot switch is required for first-error-safe control of the medical device.

[0019] When using the operating device according to the invention, this foot switch is always located on the user's foot. When changing operators, there is no need to move a conventional foot switch from one person to another in the operating room. It is sufficient for each operator to wear a shoe equipped with an operating device according to the invention.

[0020] In another embodiment of the invention, the operating device according to the invention is designed as part of the user's spectacles. These are preferably medical spectacles, in particular surgical spectacles or safety spectacles, or another type of spectacles. The operating device can again be designed as an integrated component of the spectacles, or the operating device can be detachably attached to the spectacles, for example by forming a magnetic connection, a locking, snap-in or clamping connection, or another suitable mechanical connection. By attaching the operating device to the spectacles in this way (also detachably), the operating device becomes part of the spectacles and thus part of the equipment within the meaning of the invention.

[0021] Advantageously, the mobile operating device is provided with fastening means which have a detachable attachment to other suitable operating locations, in particular to objects. These objects are preferably operating tables or other furniture or medical objects in the operating room, or the medical device itself. The operating device is therefore not only designed as an element that can be carried by the user, but in a preferred embodiment of the invention can also be used at a distance from the user if it is not arranged on the user themselves. The advantage here is that the operating device can be attached in almost any position with the aid of suitable fastening means, in particular exactly where the user needs the operating device during their work. While the user is working, they can also place the operating device in different positions one after the other.When the control device is positioned away from the user, typically not all of the control device's functions are available, especially those directly dependent on the user's body movements. In these cases, the control device preferably serves as a particularly flexibly positioned, sterile input option, particularly as a sterile mouse replacement.

[0022] In a preferred embodiment, the operating device comprises at least one manually operable switch as an operating element. This is preferably a mechanical switch, wherein the switch is preferably actuated directly, i.e. immediately via an actuating part. Depending on the type of use of the operating device, switches with a wide variety of actuating parts can be used, in particular toggle or rocker switches or buttons, but also rotary switches, in particular rotary controls. In the simplest case, the operating device therefore serves to implement a simple switching function, in particular an on / off function. Instead of a mechanical switch, a touch or proximity switch can also be used, for example a capacitive sensor or the like.

[0023] In a preferred embodiment of the invention, the operating device comprises a touchpad as the operating element. Such an operating element with a touch-sensitive surface enables input in two dimensions, in particular the possibility of operation using gestures such as swiping, tapping and holding, or scrolling. If the touchpad has a pressure-sensitive operating surface, a third input dimension can also be realized by detecting the strength of the pressure exerted on the touchpad and using it to generate the operating signal.

[0024] The mobile operating device is preferably designed to be portable, meaning that it can be worn by the user as part of their clothing or equipment, close to their body, so that a body movement or movement of a body part of the user inevitably results in a corresponding movement of the operating element. In a preferred embodiment of the invention, the operating device comprises a number of position and / or attitude sensors as operating elements. Acceleration sensors (accelerometers) and / or rotation rate sensors (gyroscopic sensors) and / or other suitable sensors or measuring devices are preferably used as position and / or attitude sensors, optionally in conjunction with magnetic field sensors (magnetometers) to improve accuracy. Thus, the position (location in space) and / or attitude (orientation in space) of the operating device can be detected and used to generate a corresponding operating signal.

[0025] The operating device according to the invention can have additional operating elements, for example, a microphone and / or a (video) camera for recording audio or image signals, which can also be used as an operating signal or to generate an operating signal. This is particularly advantageous when the operating device is placed in or on the user's glasses.

[0026] Furthermore, the operating device according to the invention can comprise feedback elements, for example, for providing feedback on a successful or failed operation. This can be, for example, visual, acoustic, or haptic feedback. Since the operating device, as part of the user's clothing or equipment, is usually worn directly on the user's body or at least close to the body, haptic feedback is preferred, particularly implemented with the aid of a vibration sensor. In this way, reliable feedback can be ensured with minimal effort.

[0027] The operating device according to the invention is preferably battery-operated or otherwise wirelessly powered. A battery is also understood to mean a rechargeable battery (accumulator). The power supply ensures the operation of the operating elements and the transmitting unit, as well as the other electrical and / or electronic components contained in the operating device. This is, in particular, a data processing and control unit with means for forwarding the operating signal received from the operating elements to the transmitting unit and / or for generating the operating signal from input or sensor values ​​received from the operating elements.

[0028] The transmitting unit is designed for wireless transmission of the operating signal. Suitable transmitting units with low power requirements are known. Preferably, the transmitting unit is designed for radio transmission. Alternatively, optical transmission methods, particularly using infrared radiation, etc., are also possible.

[0029] Particularly to protect the electrical / electronic components, it is advantageous if the control device is fully encapsulated. For this purpose, the control device preferably has a waterproof housing. The housing preferably meets the requirements of protection class IP65.

[0030] In a preferred embodiment of the invention, the operating device is enclosed in a casing that ensures sterile operation, i.e., operation under sterile conditions or in a sterile environment. To enable sterile operation, the casing is preferably designed to be sterilizable (e.g., autoclavable). In this case, the casing is preferably designed as a reusable element. Alternatively, it is a sterile disposable casing, for example, in the form of a plastic capsule.

[0031] The cover is preferably an additional element that encloses the housing of the operating device. Alternatively, the housing of the operating device itself is designed as a cover for sterile operation. The cover is designed to allow the operation of touch-based control elements (e.g., switches, touchpads), for example, as a flexible or elastic cover.

[0032] Such a cover enables sterile, touch-based operation of the mobile control device. This is particularly important in the operating room environment and distinguishes the control device according to the invention from conventional control devices or other components of the human-machine interface, such as keyboards or a computer mouse, which only allow sterile operation under special, usually complex, conditions.

[0033] In addition to the touch-based sterile operation of the mobile operating device according to the invention, the use of position or orientation sensors also enables contactless sterile operation of the medical device via the operating device. It is often advantageous if the operating device can be operated both touch-based and contactless sterile. The operating device is preferably designed so that the user can choose between one of these two operating modes depending on the specific circumstances. In any case, a combination of touch-based and contactless operating elements leads to improved operability of the medical device.

[0034] The operating device according to the invention can be designed very simply, so that only a simple on / off function is implemented. However, with the help of the touchpad or the position and / or orientation sensors, even complex movements of the user can be recorded if necessary. In particular, it is possible to record the movement of the user's body or a part of the user's body in space, i.e., three-dimensionally. This results in a multitude of advanced operating options. This is particularly true when several of the aforementioned operating elements are combined in a mobile operating device, for example, a mechanically actuated switch with a touchpad or a touchpad with position and / or orientation sensors.

[0035] For example, if a control device integrated into a shoe incorporates position or orientation sensors, the user's foot position or any change in foot position can be detected. This not only affects the angle of the foot on the ground. At the same time, it can also detect whether the foot is lifted off the ground. It is particularly advantageous if both shoes are equipped with mobile control devices. This allows the relative position of both feet to be evaluated.

[0036] Optionally, the contact between the user's body and the operating device that is possible with the operating device according to the invention can be used to transmit a body-guided signal into the user's skin via a capacitive coupling between the sole of the user's foot and the operating surface of the touchpad, which signal can be used to uniquely identify the user when operating suitable touchscreens and buttons on the X-ray device, as described in DE 10 2013 215 809 A1.

[0037] The operating device according to the invention also enables the implementation of a novel operating concept for medical devices, in which complex processes can be controlled, or at least triggered and / or confirmed, using simple operating commands. The invention thus meets the widespread desire of users for simplified device operation. Ideally, the medical device would then no longer be operated using complex control panels with countless operating functions and options, but exclusively or at least primarily through very simple operating actions, "at the push of a button," so to speak, using the operating device according to the invention, which functions like a "one-button machine."

[0038] The invention relates to human-machine interfaces in medical devices, particularly in medical imaging devices. In particular, the invention relates to the sterile operation of medical devices. However, the invention is also applicable in connection with the operation of medical devices in non-sterile areas. The invention is particularly advantageously applicable to medical imaging devices with foot-operated input devices and / or to medical imaging devices operated by users wearing medical glasses, such as surgical glasses or safety glasses, or other types of glasses. This applies, for example, but not exclusively, to C-arm X-ray devices.

[0039] The above-described properties, features, and advantages of this invention, as well as the manner in which they are achieved, will become clearer and more readily understood in connection with the following description of the embodiments, which are explained in more detail in conjunction with the drawings. Fig. 1 a surgical shoe with removable operating device, Fig. 2 an operation of a touchpad of an operating device, Fig. 3 an operation of a touchpad of an operating device, Fig. 4 an operating device suitable for free placement, Fig. 5 a surgical goggle with attached operating device, Fig. 6 an alternative placement of an operating device, Fig. 7 a representation of the components of the operating device.

[0040] All figures depict the invention only schematically and with its essential components. Like reference numerals correspond to elements with the same or comparable function.

[0041] In a first embodiment of the invention, a mobile operating device 1 for a C-arm X-ray device 2 is integrated in a surgical shoe 3, see Fig. 1. The operating device 1 has a completely encapsulated, waterproof housing 4 which can be inserted into an autoclavable cover 5.

[0042] As in Fig. 7, the operating device 1 comprises a data processing and control unit 6 and a transmitter 7 for establishing a radio connection to a receiver 9 connected to the control unit 8 of the X-ray device 2. The signal transmission between transmitter 7 and receiver 9 preferably takes place via an energy-saving Bluetooth connection or the like. The transmitter 7 is thus designed as a radio transmitter which is connected to the data processing and control unit 6 of the operating device 1. The pairing of the operating device 1 with the medical device 2 takes place either manually or by means of an integrated NFC / RFID tag or the like, which must be registered once on a sensor surface 11 provided for this purpose on the medical device 2, whereupon the pairing takes place automatically.

[0043] For power supply, the operating device 1 comprises a preferably rechargeable battery 12. Recharging advantageously takes place inductively via a suitable support 13 on the medical device 2, for which purpose corresponding charging electronics 14 are provided in the operating device 1, or via energy harvesting means integrated into the surgical shoe (not shown). For this purpose, structures can be integrated into the sole of the surgical shoe that generate electrical energy by means of energy harvesting through mechanical deformation of the sole or temperature differences between foot temperature and room temperature. This can extend the operating time of the integrated battery 12.

[0044] The advantage of this control device 1, which can be worn close to the body by the user, is that the user does not need to have their hands free to operate the medical device 2, since all interaction takes place with the feet 15 or the toes 16. In this embodiment, the control device 1 is inserted as a removable element through a resealable opening 17 into a designated receptacle 18 in the sole 19 of the surgical shoe 3, for example a rubber clog, preferably from the toe side, see arrow 21, which shows the direction of insertion. The control device 1 is designed for both the right and left shoe 3. Since these shoes 3 are frequently steam sterilized, the removable form is advantageous for increasing the service life of the electrical / electronic components 6, 7 and the battery 12. With careful selection of the electronic components, a permanent, sealed integration of the control device 1 into the shoe 3 is also conceivable.It would also be possible, particularly with a very simple and therefore inexpensive operating device 1, to use the surgical shoe 3 only once.

[0045] The operating device 1 comprises a number of operating elements. As the first, directly operable operating element, the operating device 1 has an integrated touchpad 22 with an optional pressure sensor. The touchpad 22 is connected to the data processing and control unit 6 of the operating device 1. The preferably capacitive touchpad 22 is preferably positioned as part of the operating device 1 such that, after the operating device 1 has been inserted into the receptacle 18 of the shoe sole 19, it lies beneath the insole 27 of the shoe 3, directly beneath the toes 16 of the foot 15, in particular such that bending and "swiping" of the big toe as well as pressing the toe onto the touchpad 22 can be detected; see also the directions of movement symbolically represented by arrows in Fig. 2. For example, a "scrolling" function can be implemented by bending the big toe. In conjunction with "swiping," this interaction can be used, for example, to control the image cursor of a display device 23 of the X-ray machine 2 or to zoom in / out on displayed image data. Furthermore, this touchpad 22 can also be used as a foot switch integrated into the shoe 3, for example, to trigger radiation with the toe 16.

[0046] As a second, indirectly operable operating element, the operating device 1 has position and / or orientation sensors 24, in particular three-dimensional sensors for orientation / position, acceleration, and magnetic field, which are connected to the data processing and control unit 6 of the operating device 1. These sensors 24 are used, for example, to detect a pivoting of the tip of the foot 15 to the right or left. This command can, for example, be used in the respective context to scroll backwards / forwards through displayed image data. Operating signals can also be generated, for example, by raising the foot 15, a defined inclination of the foot 15, etc.

[0047] In order to prevent incorrect operation, particularly when safety-critical functions of the X-ray device 2 are to be operated, a special activation sequence can be provided which must be triggered by the user before corresponding interactions, e.g. circling the tip of the foot 15, executing a special tapping pattern of the toes 16 or similar. This activation sequence must then first be detected by the existing sensors before the subsequent interactions are enabled.

[0048] Particularly critical functions can also be implemented in such a way that they must be triggered simultaneously with both feet 15 or with the toes 16 of both feet 15. For this purpose, both surgical shoes 3 can be equipped with the mobile input device 1. When using control elements in both shoes, for example, the function of a typical foot switch with two pedals can be transferred accordingly to the touchpads 22 of the left and right shoes 3. Furthermore, the touchpad 22 can also be used as an additional dead man's switch, which is necessary for triggering other, safety-critical functions, e.g., for moving the X-ray device 2 or triggering an X-ray scan.

[0049] In addition, the operating device 1 has a vibration sensor 25 for haptic feedback. The vibration sensor 25 can be used to provide tactile feedback to the foot 15 or the sole of the foot and / or the toes 16, e.g., to indicate that an operation has been accepted. The vibration sensor 25 is connected to the data processing and control unit 6 of the operating device 1.

[0050] Optionally, a module 26 connected to the data processing and control unit 6 of the operating device 1 is provided for coupling skin-guided signals.

[0051] As a second embodiment of the invention, a more or less freely positionable mobile operating device 1 for a C-arm X-ray device 2 is described, see Fig. 4. This operating device 1 can be attached in particular to a surgical glasses 28, see Fig. 5. However, another placement is also possible, for example on an operating table 29 or on the X-ray machine 2 itself, see Fig. 6. The basic structure of this operating device 1 is largely identical, or at least similar, to the structure of the operating device 1 integrated in the shoe 3.

[0052] The operating device 1 can be inserted into an autoclavable sleeve 5, alternatively into a sterile disposable plastic capsule, and can thus be operated under completely sterile conditions. In addition to the position and / or orientation sensors 24 and a touchpad 22, the operating device 1 has a number of switches 31 that can be manually operated independently of the touchpad 22, in particular in the form of touch-sensitive buttons, for implementing simple on / off input signals. Furthermore, a microphone 32 is provided, which is preferably designed as a bone conduction microphone, in particular for the embodiment of the operating device 1 to be attached to the glasses 28. Optionally, a video camera 33 is provided, in particular for the embodiment to be attached to the glasses 28.

[0053] In the embodiment of the operating device 1 intended for attachment to the surgical glasses 28, it is advantageous that the user has both hands free to operate the X-ray device 2. If the user has his hands free, he can optionally operate the integrated touchpad 22 and / or the number of switches 31 while wearing a sterile glove. The operating device 1 thus preferably serves as a sterile mouse replacement.

[0054] If the user is unwilling or unable to use their fingers to operate the touchpad 22 or the switches 31, the position and / or orientation sensors 24 can detect the user's head movements. This allows the user to confirm dialogs with yes / no, for example, by nodding or shaking the head. Furthermore, moving the head can be used, for example, to scroll through images or change image parameters depending on the system context.

[0055] To prevent operating errors, this variant provides for the integration of an activation sequence that is entered before a control interaction, e.g., a movement pattern for the head or, alternatively, a voice command that can be picked up by the integrated microphone 32 and clearly assigned to the active user. Alternatively, the microphone 32 can also be used to record additional voice commands from the user, thereby enabling user-specific speech recognition that only accepts commands from the wearer of the control device 1.

[0056] The optionally integrated, forward-facing camera 33 also allows live video sequences or still images from the user's perspective to be recorded on command, which is advantageous for telemedicine, training and documentation purposes.

[0057] In the embodiment of the operating device 1 intended for free placement, even away from the user, which can in particular be the type of the operating device 1 that can be attached to the surgical glasses 28, this can, for example, be flexibly attached to the operating table 29 or nearby to a suitable holder using a clip attachment (not shown). Magnetic attachment is also conceivable. Furthermore, the operating device 1 can also be attached to other surfaces, including the X-ray machine 2 itself, for example, if the user wants to operate a specific function at a specific location. On the operating table 29 or nearby, the operating device 1 can then serve, primarily with the aid of the touchpad 22, as a sterile, space-saving mouse replacement for remote control of the mouse cursor on the display device 23 or on the imaging system of the medical device 2.

[0058] In a particularly advantageous mechanical embodiment, the operating device 1 can have a cylindrical housing 4 and simulate a rotary control, see Fig.4. The touchpad 22 is mounted on the upwardly facing top surface of the cylinder as an operating element. Preferably equipped with a magnetic holder 34 provided on the bottom surface of the cylinder, the operating device 1 is removable as needed and can be flexibly repositioned on suitable surfaces. Surrounded by the casing 5, the operating device 1 can be operated in a sterile manner. The operating movements, e.g., when turning the control, are preferably detected by integrated acceleration / position sensors 24. In this variant, the user can intuitively turn the housing ring 35 arranged between the touchpad 22 and the magnetic holder 34 like a rotary control. This rotation is detected by the sensors 24 inside the operating device 1 and, depending on the context, converted into a meaningful operating interaction, e.g., for adjusting the image brightness and contrast of the display device 23 of the X-ray device 2.The operating interaction can either be derived from the context of the clinical workflow, or the user can assign their preferred functions ("favorites") to the operating device 1 via a suitable software interface and use the operating device 1 for quick access to certain functions, e.g., for "calling up patient registration," "triggering radiation," "releasing the C-arm brakes," "switching on the laser light sight," etc. Optionally, the operating device 1 can be equipped with additional buttons (not shown) for defining such "favorites." Furthermore, it can be provided that the housing ring 35 and / or the touchpad 22 itself are designed like a switch and can be tapped or pressed down, e.g., to confirm commands.

[0059] Optionally, the operating device 1 can be equipped with means 36 for optical and / or acoustic feedback. For example, light elements can be provided which, for example, indicate the confirmation / rejection of a function by glowing green / red. The light elements can also indicate whether the operating device 1 is connected to the medical device 2. Furthermore, the light elements can also be used to indicate the currently active function by color coding when several operating devices 1 are used simultaneously in an operating room and / or with an X-ray device 2, e.g., a blue light indicates the operation of the blue orbital rotation brake of the C-arm X-ray device 2.

[0060] In summary, this allows the realization of a space-saving control element 1 that can be operated from the sterile field and is flexibly positioned and can be individually configured with the functions preferred by the user.

[0061] If the user can no longer find an operating device 1, an audible signal can be played using the optionally installed acoustic sensor 36, which makes it easy to find it. An alarm can also be triggered if the operating device 1 is removed from the range of the X-ray device 2.

[0062] Although the invention has been illustrated and described in detail by the preferred embodiment, the invention is not limited to the disclosed examples and other variations may be derived therefrom by those skilled in the art without departing from the scope of the invention.
