[0056] The following further describes the present utility model in conjunction with the embodiments shown in the accompanying drawings.

[0057] Direction terms mentioned in the present utility model, such as "inner", "outer", etc., are only in reference to the way of the accompanying drawings. Therefore, the direction terms used are for explaining and understanding the present utility model, rather than for limiting the present utility model.

[0058] As Figure 1 , Figure 2 shown, as Figures 5 to 17 shown, the driving device for a surgical robot of the present utility model includes: an assembly frame plate 10, a plurality of driving motors 20, at least one driver 30, and a controller. Among them,

[0059] The assembly frame plate 10 includes a first assembly frame plate 101 and a second assembly frame plate 102 fixedly connected to the first assembly frame plate 101.

[0060] The plurality of driving motors 20 are all arranged on the first assembly frame plate 101 (as Figure 5 shown). The power output end of each driving motor 20 penetrates out of the first assembly frame plate 101 outward to connect to an external device and provide driving power for the external device.

[0061] At least one driver 30 is arranged on the second assembly frame plate 102. At least one driver 30 is electrically connected and communicatively connected to the controller and the plurality of driving motors 20. At least one driver 30 is used to make the plurality of driving motors 20 respectively output corresponding powers according to the instructions of the controller, so as to provide multiple driving powers for the external device.

[0062] Among them, at least one driver 30 has a supporting software program capable of converting instructions from the controller into control signals recognizable by a plurality of drive motors 20, so that the plurality of drive motors 20 respectively output corresponding power, thereby providing multiple driving powers for external devices. For example, the driving device can provide driving power for the surgical robot execution device and can control the position, speed, and / or torque of the surgical robot execution device. By arranging the plurality of drive motors 20 on the first assembly frame plate 101 and arranging at least one driver 30 on the second assembly frame plate 102, the distance between the plurality of drive motors 20 and at least one driver 30 can be made relatively close, and then the plurality of drive motors 20 and at least one driver 30 can be arranged in the limited space enclosed by the first assembly frame plate 101 and the second assembly frame plate 102, so as to realize the configuration of the plurality of drive motors 20 and at least one driver 30 in the surgical robot execution device with limited space (including the driving device for the surgical robot), enabling the execution device to meet the functional requirements of doctors for operating passive medical devices, and having good stability and reliability. And by arranging the plurality of drive motors 20 and at least one driver 30 in the limited space enclosed by the first assembly frame plate 101 and the second assembly frame plate 102, the electromagnetic shielding performance of active components can be improved. At the same time, since the distance between the plurality of drive motors 20 and at least one driver 30 is relatively close, it is possible to avoid cable (including power cable, communication cable, and / or encoder cable) breakage, short circuit, open circuit, communication interruption, and / or excessive cable impedance, thereby improving the control accuracy of the surgical robot and reducing the failure risk. And the configuration of the plurality of drive motors 20 and at least one driver 30 can meet the requirements of wiring, cable routing, process, maintenance, heat dissipation, and electromagnetic interference immunity.

[0063] In a specific embodiment, as Figure 1 shown, at least one driver 30 includes a plurality of single-axis drivers 301.

The plurality of single-axis drivers 301 are electrically connected and communicatively connected to each other. Among them, the plurality of single-axis drivers 301 and the plurality of drive motors 20 are in one-to-one correspondence and are serially communicative. Although the number of cables is increased to some extent, the limited space enclosed by the first assembly frame plate 101 and the second assembly frame plate 102 can be fully utilized according to actual needs, and the surgical robot can be controlled to achieve accurate, fast, and / or predictable surgical operation purposes. At the same time, if a certain single-axis driver 301 fails, only the corresponding single-axis driver 301 needs to be replaced, with a simple structure and convenient use.

[0064] In a specific embodiment, as Figure 1 、 Figure 21As shown, the number of single-axis drivers 301 and the number of drive motors 20 are both twelve. Among them, the number of single-axis drivers 301 and the number of drive motors 20 can be set according to actual needs. For example, when the outer catheter 40 in the surgical robot execution device needs to move, rotate, and / or bend, three drive motors 20 are required to drive the corresponding actions. When the middle catheter 50 in the surgical robot execution device needs to move and / or perform two bending actions, three drive motors 20 are required to drive the corresponding actions. When the inner catheter 60 in the surgical robot execution device needs to perform handle axial movement, handle axial rotation, control of the locking rod, control of the lifting and capturing of the capture arm, and / or control of the opening or closing of the implant clip's large arm, six drive motors 20 are required to drive the corresponding actions.

The first multi-axis driver 302, the second multi-axis driver 303, and the third multi-axis driver 304 are electrically connected and communicatively connected to each other. Among them, by respectively electrically connecting and communicatively connecting the first multi-axis driver 302, the second multi-axis driver 303, and the third multi-axis driver 304 to a plurality of drive motors 20, the number of cables can be reduced and actual needs can be met.

The third multi-axis driver 304 is electrically and communicatively connected to six drive motors 20, and can meet the actual needs. For example, the first multi-axis driver 302 is electrically and communicatively connected to three drive motors 20, and can meet the needs of the outer catheter 40 in the surgical robot execution device for moving, rotating, and / or bending. The second multi-axis driver 303 is electrically and communicatively connected to three drive motors 20, and can meet the needs of the middle catheter 50 in the surgical robot execution device for moving and / or two bending actions. The third multi-axis driver 304 is electrically and communicatively connected to six drive motors 20, and can meet the needs of the inner catheter 60 in the surgical robot execution device for handle axial movement, handle axial rotation, control of the locking rod, control of the lifting and capturing of the capture arm, and / or control of the opening or closing of the large arm of the implant clip.

And with the design of the output end of the driving motor 20 being matched and connected to the input end connection component 901, the smooth transmission between the driving device and the transmission cabin 90 is realized, and the modular design of the driving device and the transmission cabin 90 is achieved, improving the flexibility of the execution device in use and helping to expand the execution device to more surgical applications.

[0083] In a specific embodiment, as Figures 3 to 5 shown, the driving device further includes a bottom case 104 and a top cover 105 buckled on the top of the bottom case 104. The bottom case 104 and the top cover 105 enclose an accommodation space, and a driver assembly component 100 and all the driving motors 20 are installed in the accommodation space. The driver assembly component 100 is communicatively connected to the motor assembly component 80.

[0084] In a specific embodiment, as Figures 18 to 20As shown, the drive cabin 90 includes a chassis assembly 902, and a first adapter drive assembly 903, a second adapter drive assembly 904, and a third adapter drive assembly 905 that can move relative to the chassis assembly 902. The first adapter drive assembly 903 has a first drive module detachably connected to the first adapter assembly 110. The second adapter drive assembly 904 has a second drive module detachably connected to the second adapter assembly 120. The third adapter drive assembly 905 has a third drive module detachably connected to the third adapter assembly 130. Among them, the drive device drives the first adapter assembly 110 through the first drive module, which can ensure that the first adapter assembly 110 can complete a predetermined action. The drive device drives the second adapter assembly 120 through the second drive module, which can ensure that the second adapter assembly 120 can complete a predetermined action. The drive device drives the third adapter assembly 130 through the third drive module, which can ensure that the third adapter assembly 130 can complete a predetermined action. At the same time, the first adapter drive assembly 903, the second adapter drive assembly 904, and the third adapter drive assembly 905 are all driven by motors, with good controllability, and can output speed, position, and even force as needed; at the same time, the above structure has high flexibility, which enables the drive cabin 90 to replace different adapter drive assemblies according to needs to meet different surgical procedure requirements.

[0085] In a specific embodiment, the surgical robot is an interventional surgical robot, which can meet actual needs.

[0086] In a specific embodiment, as Figure 20 、 Figure 21 shown, the first adapter assembly 110 is used to connect to the outer catheter 40. The second adapter assembly 120 is used to connect to the middle catheter 50. The third adapter assembly 130 is used to connect to the output end of the inner catheter 60. Among them, the drive device drives the outer catheter 40 to perform corresponding actions through the first adapter assembly 110. The drive device drives the middle catheter 50 to perform corresponding actions through the second adapter assembly 120. The drive device drives the inner catheter 60 to perform corresponding actions through the third adapter assembly 130. The design of separately driving the outer catheter 40, the middle catheter 50, and the inner catheter 60 helps to improve the flexibility of the mitral valve repair instrument's actions and facilitates the implementation of fine operations on the mitral valve repair instrument. Applying the above-mentioned actuator to complete the valve repair surgery can further ensure the stability and accuracy of the surgery. By separately driving the first adapter assembly 110, the second adapter assembly 120, and the third adapter assembly 130, the actuator helps to improve the flexibility of the actions output by the adapter assemblies, facilitating the fine operations required by the surgical procedure, thereby making the operation of the actuator more precise, stable, and safe.

And whether it is the simple movement of the single-axis driver 301, or the synchronization, flying saw and / or tension compensation of the first multi-axis driver 302, the second multi-axis driver 303 and the third multi-axis driver 304, the real-time performance of the movement of the plurality of driving motors 20 can meet the requirements, so as to ensure that the doctor can control the intervention surgical robot to achieve accurate, fast and / or predictable surgical operation purposes. Moreover, when the driving device for a surgical robot is in use, it is installed on the right side of the transmission cabin 90.
