At the same time, the quick disassembly part can be used to ensure the normal disinfection and replacement of surgical instruments. The power transmission part adopts the traditional synchronous belt transmission mechanism, which can realize single degree of freedom adjustment.

[0027] In addition, the present invention can maintain a certain rigidity of the continuum robot arm while increasing the working space. It does not rely on multiple sections in series to increase the working space, which reduces the difficulty of modeling in the design process and satisfies the curvature bending assumption of flexible instruments.

Moreover, the slide mechanism in the present invention can only be adjusted along the single degree of freedom of the front and back, which can resist the radial force at the execution end to a large extent and maintain the linear output displacement of the slide. In addition, through the transmission of the synchronous belt, the output accuracy can also be guaranteed to avoid slipping and dislocation. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] See also Figures 1 to 12 This embodiment provides an integrated double-range slide for continuous flexible devices, including: a base 1000, a mechanical fixing seat 2000, a primary slide 3000 and a secondary slide 4000,

[0045] The primary slide 3000 is arranged on the base 1000, the secondary slide 4000 is arranged on the primary slide 3000, the mechanical fixing seat 2000 is arranged on the secondary slide 4000, and the continuous body flexible device is detachably arranged at the front end of the mechanical fixing seat 2000;

[0046] The main slide 3000 includes a driver 3200, a first synchronous belt 3302 mechanism 3300, a synchronous belt fixing seat 3108, a bottom plate 3500 and a moving part. The bottom plate 3500 is detachably arranged on the base 1000. The first synchronous belt 3302 mechanism 3300 is arranged at the bottom plate 3500. The driver 3200 is used to drive the first synchronous belt 3302 of the first synchronous belt 3302 mechanism 3300 to rotate. The moving part is fixed to the rear bottom edge of the first synchronous belt 3302 so that the moving part moves forward and backward along the bottom plate 3500. The synchronous belt fixing seat 3108 is fixedly arranged at the front end of the bottom plate 3500.

[0047] The secondary slide 4000 includes a second synchronous belt 4202 mechanism 4200, an intermediate plate 4400, a sliding plate 4103 and an upper pressing plate 4104. The second synchronous belt 4202 mechanism 4200 is arranged at the intermediate plate 4400, and the sliding plate 4103 is arranged above the second synchronous belt 4202 mechanism 4200.

[0048] The mechanical fixing seat 2000 is detachably arranged at the front end of the sliding plate 4103, and the upper pressure plate 4104 is arranged below the rear end of the sliding plate 4103. The upper pressure plate 4104 and the sliding plate 4103 clamp the upper rear side of the second synchronous belt 4202 of the second synchronous belt 4200 mechanism 4200, and the movable part is detachably connected to the rear end of the bottom surface of the intermediate plate 4400, and the synchronous belt fixing seat 3108 clamps the lower front end of the second synchronous belt 4202.

[0049] It should be noted that, in the present embodiment, both the first synchronous belt 3302 and the second synchronous belt 4202 cannot realize turnover, which is caused by the limitations of the synchronous belt fixing seat 3108 , the moving part and the upper pressure plate 4104 .

[0050] When in use, the driver 3200 drives the first synchronous belt 3302 to rotate, driving the moving part to move forward, pushing the middle plate 4400 to move forward, and at the same time, the front end of the second synchronous belt 4202 is fixed by the synchronous belt fixing seat 3108, so that the second synchronous belt 4202 rotates and moves forward relative to the middle plate 4400, and the sliding plate 4103 above the second synchronous belt 4202 moves forward, so that the mechanical fixing seat 2000 drives the continuous body flexible device to move forward. In this way, only by driving the first synchronous belt 3302 to rotate by a driver 3200, the middle plate 4400 and the sliding plate 4103 can be driven to move forward relative to the bottom plate 3500, and the forward movement of the middle plate 4400 and the sliding plate 4103 is superimposed on each other, so as to realize the double-range movement of the entire slide. In this way, the continuum flexible instruments used in medical surgery can be used to expand their working space and solve the limitation problem of the application of flexible surgical instruments, making them not only suitable for facial and neck tumor resection surgery, but also for laparoscopic tumor resection surgery, greatly expanding the working space of continuum surgical instruments and taking up less space.

A lower slider 3102 is fixed to each of the vertical plates 3103, and each of the lower sliders 3102 cooperates with a lower guide rail 3101 to make the lower slider 3102 move forward and backward along the lower guide rail 3101.

[0054] On the one hand, the two lower guide rails 3101 are used to improve the support rigidity of the main slide 3000 during movement. On the other hand, the overall volume of the main slide 3000 is fully reduced through the cooperation between the moving part and the bottom plate 3500, especially the space occupied by the first synchronous belt 3302 mechanism 3300 and the moving part.

[0055] See also Figures 1 to 12 Furthermore, the driver 3200 includes: a motor fixing seat 3201, a driving motor 3202, a bearing 3205 seat 3204, a bearing 3205, a pin 3206 and a bearing 3205 pressure cover, the motor fixing seat 3201 and the bearing 3205 seat 3204 are fixed at the rear end of the base plate 3500, the driving motor 3202 is fixed on the motor seat, the bearing 3205 is fixed on the bearing 3205 seat 3204 through the bearing 3205 pressure plate, the first rear wheel 3203 is fixed on the output shaft of the driving motor 3202, and the two ends of the pin 3206 are respectively interference fit with the first rear wheel 3203 and the bearing 3205.

[0060] When the magnet 3106 approaches the sensor 3107 , the driving motor 3202 stops driving the first rear wheel 3203 to rotate.

[0061] When the magnet 3106 passes through the sensor 3107, it can be sensed, which plays the role of electrical limiting.

[0062] See also Figures 1 to 12 Furthermore, the second front wheel 4201 and the second rear wheel 4203 of the second synchronous belt 4202 mechanism 4200 are respectively arranged at the front and rear ends of the middle plate 4400, and the middle plate 4400, the second front wheel 4201 and the second rear wheel 4203 are sleeved in the second synchronous belt 4202, and the second front wheel 4201 and the second rear wheel 4203 are respectively engaged with the second synchronous belt 4202.

[0063] See also Figures 1 to 12 Furthermore, the middle plate 4400 has a rectangular through hole on its surface, and the rectangular through hole extends along the front-to-back direction.

[0064] An upper guide rail 4101 is disposed on the left and right sides of the rectangular through hole, respectively. The upper guide rail 4101 is disposed parallel to the lower guide rail 3101.

The two upper sliders 4102 are placed between the two upper guide rails 4101. The upper sliders 4102 are matched with the upper guide rails 4101 in a one-to-one manner, so that the upper sliders 4102 can move forward and backward along the upper guide rails 4101.

[0066] On the one hand, the upper guide rail 4101 is clamped between the clamp arm 4105 and the upper slider 4102 through the cooperation between the clamp arm 4105 and the upper slider 4102, thereby improving the stability of the movement of the secondary slide 4000. On the other hand, through the arrangement of the rectangular through hole, the upper guide rail 4101 and the upper slider 4102 are both arranged on the side, and the space occupied by the guide mechanism is reduced.

[0067] See also Figures 1 to 12 , further comprising two second tensioning mechanisms 4300, the two second tensioning mechanisms 4300 are respectively arranged at the front and rear ends of the middle plate 4400,

[0072] On the one hand, it is convenient to install, disassemble and tension the first synchronous belt 3302 and the second synchronous belt 4202, and on the other hand, it ensures the stability of the transmission performance of the first synchronous belt 3302 and the second synchronous belt 4202. When they are loose, by tensioning, the accuracy of the first synchronous belt 3302 and the second synchronous belt 4202 in transmitting the driving force of the driving motor 3202 is maintained. In addition, when the two synchronous belts are loose, the service life of the first synchronous belt 3302 and the second synchronous belt 4202 can still be extended by adjusting the first tensioning mechanism 3400 and the second tensioning mechanism 4300.

[0073] See also Figures 1 to 12 Furthermore, the synchronous belt fixing seat 3108 is arranged between the two long through holes, the synchronous belt fixing seat 3108 is a block-shaped structure, and a front pressure plate 3109 is arranged on the synchronous belt fixing seat 3108.

[0074] It should be noted that the synchronous belt fixing seat 3108 may be provided with a mounting through hole, which penetrates the synchronous belt fixing seat 3108 along the front-to-back direction, and the first synchronous belt 3302 passes through the mounting through hole.

[0075] In this way, in order to solve the problem that existing continuum surgical instruments cannot increase the working space by connecting multiple flexible segments in series, this embodiment combines a continuum surgical instrument with a limited number of flexible segments, and reaches a deep and closed environment through a bipolar slide. While retaining the rigidity, it can be suitable for different indications. At the same time, the quick disassembly part can be used to ensure the normal disinfection and replacement of surgical instruments. The power transmission part adopts the traditional synchronous belt transmission mechanism, which can realize single degree of freedom adjustment.

[0076] In addition, this embodiment can keep a certain rigidity of the continuum robot arm while increasing the working space. It does not rely on multiple sections in series to increase the working space, which reduces the difficulty of modeling in the design process and satisfies the curvature bending assumption of flexible instruments.

[0077] The compact two-stage slide of this embodiment has a small size and high space utilization, and can be easily integrated at the surgical execution end, that is, the execution end of the surgical robot, to facilitate the disassembly and disinfection of the end instrument and the maintenance of the instrument itself.

[0078] Moreover, the slide mechanism in this embodiment can only be adjusted along the single degree of freedom of the front and rear, which can largely resist the radial force at the execution end and maintain the linear output displacement of the slide. In addition, through the transmission of the synchronous belt, the output accuracy can also be guaranteed to avoid slipping and misalignment.

[0079] Although the disclosure is disclosed as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the present invention.
