Description

Technical Field

[0001] The invention relates to a medical device, a system for calibrating an operating table (operating table) in a medical environment, a mobile device and a method for operating a medical device. Background Art

[0002] Mobile surgical systems, such as mobile C-arm X-ray systems, are usually sold without a dedicated operating table and can therefore be used in combination with multiple operating tables, often from different manufacturers. This results in an unclear position of the operating table and / or the patient lying on the operating table.

[0003] However, in many applications, such as when the mobile surgical system is powered and / or when the mobile surgical system is used as a catheterization laboratory, it is necessary to know the position of the patient and / or operating table relative to the mobile surgical system. US2021338107 and US10335241 disclose the use of an electronic inertial measurement unit ("IMU") on a surgical imaging system to determine the position of a mobile imaging device or surgical tool for optimal imaging during surgery. Summary of the invention

[0004] Therefore, the object of the present invention is to provide a medical device, a system for calibrating an operating table (operating table) in a medical environment, a mobile device and a method for operating a medical device to calibrate the relative position of the operating table.

[0005] The objects of the invention are solved by the subject-matter of the independent claims, wherein further embodiments are contained in the dependent claims.

[0006] One aspect of the present invention is to provide a medical device, which includes a mobile device and a medical system.

[0007] In particular, the mobile device is a handheld device. It comprises at least one position sensor and a wireless communication unit. The at least one position sensor is adapted to determine the position (in particular, the relative position) of the mobile device and can be calibrated relative to a reference position. The wireless communication unit is adapted to send position information to the medical system. The position information is based on a measurement result (measurement value) of the at least one position sensor.

[0008] The mobile device further comprises a mounting element for attaching the mobile device to a designated position of an operating table. For example, the designated position is a guide rail of the operating table. The mounting element is particularly suitable for releasably mounting the housing of the mobile device to the operating table.

[0009] In general, the medical system may be any medical system suitable for use with an operating table. In particular, the medical system may be mobile, such that the medical system can be moved to the operating table. Additionally or alternatively, the operating table may be mobile, such that the operating table can be moved to the medical system. In particular, the medical system comprises a mobile imaging system, such as an X-ray system. In order to enable relative movement of the medical system and the operating table, the medical system may be implemented as a C-arm device.

[0010] The medical system includes a wireless communication base unit (base station). The wireless communication base unit is adapted to receive location information sent by the wireless communication unit of the mobile device. The wireless communication base unit may be a USB-enabled transceiver wireless device, such as a USB Bluetooth transceiver module. For example, the wireless communication base unit may be mounted on a bracket of the medical system. In addition, the wireless communication base unit may also be integrated with the system software of the medical system.

[0011] The medical system further comprises a computing unit. The computing unit may be a separate dedicated computing unit, but may also be an existing computing unit of the medical system equipped with additional software enabling the existing computing unit to perform the steps listed below.

[0012] The medical system further comprises a reference position arranged to mount the mobile device. In particular, the reference position is located on the mobile imaging system. Mounting the mobile device on the medical system can be performed using the mounting element or by placing the mobile device on a marked point on the medical system. During operation of the medical device, the mobile device is placed at the reference position at least for a period of time. As a simple example, the reference position can be a marked point, such as a marked point on a support of the medical system.

[0013] The computing unit is configured to calibrate the operating table relative to the medical system (in particular, relative to the mobile imaging system). The calibration is performed after the mobile device is mounted on the operating table. The calibration may include moving the mobile device from a reference position of the medical system to a specified position of the operating table. The at least one position sensor of the mobile device can measure a position change from the reference position to the specified position, thereby knowing the position of the specified position relative to the reference position and the position of the operating table relative to the medical system.

[0014] The computing unit is further configured to store the specified position as a known position in a coordinate system of the medical system, in particular the mobile imaging system.

[0015] The computing unit is further configured to receive position information related to the measurement results of the at least one position sensor via the wireless communication base unit. In particular, the measurement results of the at least one position sensor are received not only during calibration of the operating table, but also during subsequent operation of the medical system, in particular, during a medical procedure. Thus, the position of the operating table relative to the medical system can be known during the medical procedure.

[0016] With the medical device, various operating tables can be selected. The medical system knows the position of the operating table, which can be used to better control the medical system, for example, it can be used to place the patient at the isocenter of the X-ray system, which helps to improve the 3D image quality. By knowing the position of the operating table relative to the medical system, the patient's dose can be determined more accurately. By knowing the position of the operating table relative to the medical system, the medical system can also be positioned more accurately, for example, lowering the height of the C-arm and / or bringing the detector closer to the patient, thereby reducing scattered radiation. Knowing the position of the operating table relative to the medical system also helps to prevent the medical system and the operating table from colliding when one or both of them move.

[0017] According to one embodiment, the computing unit is further configured to generate control instructions for controlling the medical system and / or the operating table based on the received position information. For example, for a CT scan, the X-ray source and the sensor must be moved relative to the patient and therefore also relative to the operating table. This can be achieved by moving the X-ray source and the sensor, moving the operating table, or moving the X-ray source and the sensor and the operating table. In order to determine the necessary movement of the X-ray source and the sensor and / or the operating table, the received position information is used and the control instructions include the determined movement.

[0018] According to one embodiment, the medical system further comprises a user interface unit. The user interface unit may be a dedicated user interface unit or a standard user interface unit with additional functions.

[0019] The calibration of the operating table can be performed using the user interface unit. This can include the following steps: asking the user to place the mobile unit at the reference position and / or confirming that the mobile unit is at the reference position through the user interface unit. The calibration of the operating table may also include: asking the user to move the mobile device from the reference position to the specified position through the user interface unit, and confirming that the mobile device has been placed at the specified position. Then, as described above, position information is received from the at least one position sensor. Using the position information, the position of the operating table relative to the medical system is determined.

[0020] According to one embodiment, the medical system further comprises a base station for the mobile device, wherein the reference position of the mobile device is located on the base station. In particular, the base station may have a groove corresponding to the outer shape of a part of the mobile device, so that the mobile device can be placed in the base station. Thus, the reference position is more clear and the subsequent measurement of the relative position of the operating table is also improved.

[0021] The base station may further include a power charging base port. The power charging base port is adapted to charge the battery of the mobile device. The charging may be performed by wired charging or inductive charging. Thus, when the mobile device is located at the reference position, the battery of the mobile device is also charged so that it is ready to operate when needed.

[0022] In another aspect of the present invention, a system for calibrating an operating table in a medical environment is provided. In particular, the medical environment may include a medical system (such as a medical imaging system), and the medical system and / or the operating table are mobile.

[0023] The system comprises a mobile device, the mobile device comprising a housing, a mounting element, at least one position sensor and a wireless communication unit. Preferably, the housing encapsulates the position sensor and the wireless communication unit.

[0024] The mounting element is suitable for releasably mounting the housing to the operating table. In particular, the mounting element is suitable for mounting the housing to a designated position of the operating table, such as a guide rail of the operating table.

[0025] The position sensor is adapted to measure the position of the mobile device in a fixed coordinate system. In particular, the fixed coordinate system is a coordinate system attached to the medical system.

[0026] The wireless communication unit is suitable for transmitting the position information measured by the position sensor, and can adopt wireless standards such as Bluetooth, and its transmission range can reach several meters.

[0027] The system further comprises a computing unit, which may comprise a user interface unit. The user interface unit may be an existing user interface unit of the medical system or a dedicated user interface unit of the system.

[0028] The computing unit is arranged to receive location information from the mobile device in a wireless manner. To this end, the computing unit comprises or is connected to a wireless communication infrastructure unit that shares at least one standard and / or frequency band with a wireless communication unit of the mobile device.

[0029] The computing unit is further arranged to register (align, register, record) the operating table to the fixed coordinate system. To this end, the computing unit registers the position of the mobile device to the fixed coordinate system after the mobile device is mounted on the operating table. This can be achieved, for example, by measuring the change in position of the mobile device when it is moved from a reference position on the medical system and / or user interface unit to a specified position on the operating table.

[0030] The position of the mobile device is then registered to (registered as) a geometric predetermined reference of the operating table. The geometric predetermined reference may be a specified position, a top flat surface of the operating table, or an isocenter of the medical system. The registration data is then stored in a memory. The memory may be a memory of the user interface unit and / or a memory of the medical system.

[0031] Then, the operating table is calibrated by inputting reference values ​​corresponding to the position of the operating table in use, such as the maximum and / or minimum position values ​​of the operating table along the (multiple) directions of the fixed coordinate system. In order to obtain the maximum and / or minimum position values, the user interface unit can require the user to move the operating table to the corresponding maximum and / or minimum position values, for example, in one, two or three Cartesian coordinates (rectangular coordinates). Alternatively, the computing unit can control the operating table according to a predetermined calibration protocol related to the used operating table and the medical system (both of which are technically known / stored by the system) without interaction with the user or with limited interaction with the user. These calibration values ​​are then stored in a memory.

[0032] Alternatively or additionally, a previously calibrated operating table stored in a memory may also be read and selected, and the corresponding calibration values ​​uploaded from the memory, which can save time in calibrating previously used operating tables.

[0033] By means of the system for calibrating the operating table, various operating tables can be selected. The system learns the position of the operating table, which can be used to better control the medical system, for example to place the patient at the isocenter of the X-ray system, which helps to improve the 3D image quality. By knowing the position of the operating table relative to the medical system, the patient's dose can also be determined more accurately. By knowing the position of the operating table relative to the medical system, the medical system can also be positioned more accurately, for example by lowering the height of the C-arm and / or bringing the detector closer to the patient, thereby reducing scattered radiation. By knowing the position of the operating table relative to the medical system, it also helps to prevent the medical system and the operating table from colliding when one or both of them move.

[0034] The initial position of the operating table at the start of the medical procedure can be acquired using the mobile device and stored in a memory. In this way, the change in position of the operating table compared to the initial position can be used during the medical procedure. In this case, the medical procedure can be a surgical operation and / or a medical imaging procedure.

[0035] In another aspect of the present invention, a mobile device for calibrating an operating room table is provided. The mobile device comprises at least one position sensor. The position sensor is adapted to measure the position of the mobile device in a fixed coordinate system.

[0036] The mobile device further comprises a control unit. The control unit may in particular be a microcontroller with embedded software. The control unit is configured to receive measurement results from the at least one position sensor and to broadcast the measurement results and / or position information related to the measurement results via a wireless communication unit of the mobile device. For example, the wireless communication unit may be a Bluetooth low energy transceiver.

[0037] The mobile device further comprises a battery for providing electrical energy to the at least one position sensor, the control unit and the wireless communication unit. In particular, the battery may be a rechargeable battery. In this case, the mobile device further comprises a charging device, such as a charging adapter with a port for connecting a charger and / or a wireless charging unit.

[0038] The mobile device further comprises a mounting element for attaching the mobile device to a specified location of the operating table. In particular, the attachment device is a releasable attachment device, for example with a mounting bracket. The mobile device can be further made easy to release by a knob or similar device. In particular, the specified location is a guide rail of the operating table.

[0039] The mobile device may further comprise a housing, which in particular encloses the at least one position sensor, the control unit, the wireless communication unit and the battery.

[0040] By means of the mobile device, a calibration of the operating table can be performed. The advantages of such a calibration have been described in detail above.

[0041] According to one embodiment, the at least one position sensor is an inertial measurement unit including an accelerometer and a gyroscope, i.e. a 6-DOF sensor. By continuously measuring linear acceleration and rotational acceleration, the inertial measurement unit can provide a three-dimensional change in position, in particular movement distance and orientation (direction). In particular, the at least one position sensor may also include a magnetometer to make it a 9-DOF sensor. The use of a magnetometer can improve the measurement accuracy of the accelerometer and gyroscope, in particular, the measurement accuracy of the accelerometer and gyroscope can be improved by reducing or eliminating gyro drift or long-term drift.

[0042] In another aspect of the present invention, a method for operating a medical device is provided. The medical device comprises the above-mentioned medical device and an operating table. At least one of the medical system and the operating table is mobile so that the medical system and the operating table can be moved relative to each other to an operating position.

[0043] According to the method, the user moves the mobile device from a reference position on the medical system to a specified position on the operating table. Since the position and orientation of the mobile device at the beginning of the movement are known, the position of the mobile device relative to the medical system at the end of the movement is also known. Since the mobile device is placed at the specified position on the operating table, this position also means the position of the operating table.

[0044] In the next step, the operation console is initialized, that is, the operation console is registered in the medical device.

[0045] Furthermore, in particular, during medical procedures such as surgery or medical imaging procedures, the at least one position sensor performs measurements and the wireless communication unit of the mobile device broadcasts position information related to the measurements and the wireless communication base unit of the medical device receives the position information.

[0046] According to one embodiment, the computing unit generates a control instruction for controlling the medical system and / or the operating table based on the received position information. The control instruction can be in particular an instruction for moving components of the medical system and / or the operating table. Since the computing unit is part of the medical device, the control instructions for controlling the components of the medical system can be directly executed by the medical system. Regarding the control instructions for moving the operating table, these instructions can be executed using the connection between the medical device and the operating table, or these instructions can be displayed on a display screen (e.g., a display screen of a user interface unit), and the user can operate the operating table to perform the required movement. In the case where the user operates the operating table to perform the required movement, the measurement performed by the mobile device can be used to confirm whether the correct movement has been performed.

[0047] According to one embodiment, initializing the console comprises: moving the console to a default position. This can be performed before or after the mobile device moves from the reference position to the specified position. Based on the default position, the movement range of the console has been or will be known. If the console does not have an inherent default position, a default position can be defined, such as the leftmost, frontmost and lowest position. This definition can also be indicated on the user interface unit.

[0048] According to one embodiment, initializing the operating table includes: obtaining (implementing) an operating table movement range calibration. This movement range calibration defines at least one movement range or position range of the operating table. These ranges can be the ranges allowed when moving the table in a fixed coordinate system. In other words, this movement range calibration defines some limitations on the table movement and position, usually defined by the maximum or minimum position (or end point) or movement along at least one direction or towards at least one direction. This (obtaining the operating table movement range calibration) is particularly required when registering a new table in the medical device. In order to obtain the movement range, it is necessary to register the position of the mobile device, especially the default position, that is, save the position of the mobile device relative to the medical system. Then, in at least one of the three directions in which the operating table can move, the operating table is moved to an end point in the direction. At this end point, the position of the mobile device is registered, that is, the position of the mobile device relative to the medical system is saved. Then, the operating table is moved to another end point in the direction, and the other end point is the end point opposite to the one end point. At the other end point, the position of the mobile device is registered. Then, the movement range of the operating table in the direction can be known. If the operating table can be moved in more than one direction, the above steps are repeated for the other directions. In particular, the movement of the operating table is controlled by the user according to instructions given on the display screen of the user interface unit. In this case, the three directions can be the X direction, the Y direction and the Z direction in the coordinate system of the operating table.

[0049] According to one embodiment, the above-mentioned movement range calibration can also be performed for rotation around at least one of the three axes, wherein the three axes are particularly along the X direction, Y direction and Z direction in the coordinate system of the operating table. To this end, it is necessary to register the position of the mobile device. Then, the operating table is rotated around the axis to one end point and the position of the mobile device is registered. Then, the operating table is rotated around the axis to another end point, which is opposite to the one end point. The position of the mobile device is also registered at this position. In this way, the rotation range of the operating table can be known.

[0050] According to one embodiment, obtaining the operating table movement range calibration further comprises: moving the mobile device from the specified position to a predetermined position, and determining the offset between the specified position and the predetermined position. In particular, the mobile device is then moved back to the specified position. In an alternative embodiment, the mobile device can be moved from the reference position to the predetermined position, and then to the specified position, which can save a step of initializing the operating table. In particular, the predetermined position is a position on the top of the operating table, more particularly, a center position of the top of the operating table.

[0051] According to one embodiment, obtaining the operating table movement range calibration further includes: storing the height value of the mobile device as a reference value. Since the height above the ground of the reference position is known, the height of the mobile device at the specified position can be easily determined using the relative position of the mobile device relative to the medical device.

[0052] Once the range of motion calibration has been performed, the calibration values ​​may be saved for later use, in particular the calibration values ​​may be saved using an identifier of the operating table such as brand name, model name, serial number or colour of the operating table.

[0053] According to one embodiment, obtaining the calibration of the movement range of the operating table includes: selecting a previously calibrated operating table stored in a memory, and reading and uploading corresponding calibration values ​​from the memory. In particular, the operating table can be identified by an identifier. The selection can be performed by a drop-down menu of a user interface unit, etc. The memory can be the memory of the computing unit, that is, the memory related to the medical system, or the memory of the mobile device. By selecting a previously calibrated operating table, it is only necessary to determine the position of the mobile device relative to the medical system at the specified position without determining the movement range, thereby saving a lot of time.

[0054] According to one embodiment, initializing the operation table includes: the user selecting a position of the operation table where the mobile device is installed. In particular, the user may indicate on which rail of the operation table the mobile device is installed, such as the upper left rail, the lower left rail, the upper right rail, or the lower right rail. The user may also indicate on which side of the operation table the medical system is located, i.e., the left side or the right side.

[0055] According to one embodiment, initializing the operating table includes storing an initial position of the operating table before or at the beginning of a medical procedure. In this case, the medical procedure may be a surgical procedure or a medical imaging procedure. The position also initializes the patient position for the medical procedure, so that position changes during the medical procedure are always related to the stored initial position.

[0056] It shall be understood that a preferred embodiment of the present invention can also be any combination of the dependent claims with the independent claims.

[0057] These and other aspects of the invention will be apparent from and elucidated with reference to the embodiments described hereinafter. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] The preferred embodiments of the present invention will be described below by way of example only with reference to the accompanying drawings:

[0059] Figure 1 A schematic cross-section of an embodiment of a mobile device is shown;

[0060] Figure 2 shows a schematic side view of an embodiment of a medical device;

[0061] Figure 3a and Figure 3b An embodiment of a method for operating a medical device is shown;

[0062] Figure 4 Another embodiment of a method for operating a medical device is shown; and

[0063] Figure 5 A schematic side view of another embodiment of a medical device is shown. DETAILED DESCRIPTION

[0064] Elements with the same reference numerals in these figures are either equivalent elements or elements with the same function. If the function is equivalent, the elements discussed previously will not necessarily be discussed in the following figures.

[0065] Figure 1 A schematic cross-sectional view of an embodiment of a mobile device 1 is shown. The mobile device 1 comprises at least one position sensor 2. The position sensor 2 is suitable for measuring the relative position of the mobile device 1 and the medical system. For example, the at least one position sensor 2 may be an inertial measurement unit, which comprises an accelerometer and a gyroscope, in particular a three-axis accelerometer and a three-axis gyroscope. By means of the accelerometer and the gyroscope, the movement (including translation and rotation) of the mobile device 1 starting from a known starting position may be determined, and the final position relative to the known starting position may be determined. In order to further improve the accuracy of the position determination, the at least one position sensor 2 may also comprise a magnetometer, which may reduce or eliminate gyroscopic drift or long-term drift.

[0066] The mobile device 1 further comprises a control unit 3, such as a microcontroller. The control unit 3 receives sensor measurements and / or sensor signals from the at least one position sensor 2. The control unit 3 may process the sensor signals, for example, integrate the acceleration, to calculate the position change.

[0067] The mobile device 1 further comprises a wireless communication unit 4 which receives information from the control unit 3, such as sensor measurements or processed sensor measurements (such as position changes), and broadcasts said information, for example to a medical system.

[0068] The mobile device 1 may be powered by a battery 5. The battery 5 is connected to the at least one position sensor 2, the control unit 3 and the wireless communication unit 4, but for clarity, the connections are not shown. The battery 5 is also connected to a charging unit 6, which may be a wired or wireless (e.g. inductive) charging unit.

[0069] The position sensor 2 , the control unit 3 , the wireless communication unit 4 , the battery 5 and the charging unit 6 are all enclosed in a housing 7 .

[0070] The mounting element 8 (here described as a hook) is attached to the housing 7 or is part of the housing 7. The mounting element 8 is suitable for attaching the mobile device 1 to a designated position of the operating table (operating table), such as a rail. There may be other devices for fixing the mounting element 8 to a designated position, or a release device (such as a knob) for releasing the mobile device 1 from a designated position of the operating table.

[0071] Figure 2 A medical device 9 is shown which comprises a medical system 10 and a mobile device 1 as well as an operating console 11 .

[0072] The medical system 10 is shown as a C-arm X-ray system having a C-arm 12 and a support 13. However, various other medical systems 10 may be used, in particular medical systems 10 that require knowledge of the relative position of an operating table 11 and the medical system 10. The medical system 10 further comprises a user interface unit 14 with a display screen 15. The mobile device 1 is placed at a reference position 16 of the medical system 10, which reference position 16 may be indicated by a circumference of the mobile device 1 drawn on the support 13 of the medical system 10.

[0073] The operating table 11 has a top 17 of the operating table 11 and also includes rails 18. Furthermore, the operating table 11 is shown as a mobile operating table 11 with wheels 19. However, the present invention is also applicable to a fixed operating table 11 and a mobile medical system 10 as well as a mobile operating table 11 and a mobile medical system 10.

[0074] Before a medical procedure (eg, a surgical procedure or a medical imaging procedure) begins, console 11 may be initialized as follows.

[0075] The user interface unit 14 may provide the user with several options, such as adding a station, selecting a previously configured station, and initializing a station.

[0076] When the user chooses to add a station, the user is required to place the mobile device 1 on the reference position 16, or confirm that the mobile device 1 has been placed on the reference position 16. Then, as Figure 3a As shown, the user is required to move the mobile device 1 to a designated position 20 on the operating table 11, for example, to mount the mobile device 1 on one of the rails 18. During the movement, the mobile device 1 measures the change in its position so that the relative position of the designated position 20 and the reference position 16 can be known. Then, the user can select the orientation (direction) of the mobile device 1 on the user interface unit 14, that is, on which rail 18 of the operating table 11 the mobile device 1 is mounted. In addition, the user can also select on which side of the operating table 11 the medical system 10 is located.

[0077] Before or after moving the mobile device 1 to the designated position 20, the user may be asked to place the operating table 11 in a default position, such as a default position provided by the table or a predetermined default position, such as a minimum height, toward the patient's legs and on the patient's rightmost side.

[0078] After moving the mobile device to the designated position 20 and placing the operation platform 11 at the default position, the user is required to move the operation platform 11 along the Figure 3b The user is asked to move at least one or all three directions indicated by the arrows to the maximum and / or minimum position, and if applicable, the user is asked to rotate the operating table 11 around at least one or all available axes to the maximum and / or minimum position. The position sensor 2 of the mobile device 1 will record these movements so that the medical device 9 can know the extreme positions of the operating table 11. The procedure ends with the user selecting to initialize the table. In this step, a name or label can also be assigned to the table to enable the table to be selected later, thereby saving the step of finding the maximum range of movement.

[0079] When a previously configured operating console 11 is selected from the drop-down menu, the user only needs to move the operating console 11 to the default position and move the mobile device 1 from the reference position 16 to the specified position 20 .

[0080] Another embodiment of a method for operating a medical device 9 comprises Figure 4 The additional step shown. Here, the mobile device 1 is moved from the designated position 20 to a predetermined position 21, in particular a predetermined position 21 on the top 17 of the operating table 11, for example, where the patient is or will be located. Once the relative position of the predetermined position 21 to the designated position 20 and therefore the relative position of the predetermined position 21 to the reference position 16 has been determined, the mobile device 1 is moved back to the designated position 20. Knowing the predetermined position 21 on the top 17 of the operating table 11 enables a more accurate placement of the operating table 11 relative to the medical system 10.

[0081] exist Figure 5 In another embodiment shown, a base station 22 is arranged on the support 13 of the medical system 10. The base station 22 is suitable for receiving the mobile device 1 and providing a reference position 16 for the mobile device 1. In addition, the base station 22 may also include a power charging base port for charging the battery 5 of the mobile device 1.
