[0035] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0036] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] Please refer to the instruction manual Figures 1-9 The utility model discloses a surgical instrument auxiliary frame, which mainly includes a hand rest 1, a sliding block 2, a buckle seat 4, a buckle structure 6, an outer cylinder 7, an inner cylinder 9, a fixed seat 11 and a motor 12. The hand rest 1 is arc-shaped, and an arc-shaped notch 13 is opened at its front end. When in use, the doctor places his arm and elbow on it for support, and the sliding block 2 is arranged below the hand rest 1. Both sides of the top of the sliding block 2 are fixedly connected to a rack 3; the buckle seat 4 is fixedly connected to the rear of the bottom end of the hand rest 1, and the buckle seat 4 is fixedly connected to the rear of the bottom end of the hand rest 1. A cavity is provided in the base body, and the buckle seat 4 is slidably connected to the outside of the slider block 2 and adapted to the shape of the slider block 2, that is, the buckle seat 4 can slide on the slider block 2 to adjust the position of the hand rest 1. The front and rear ends of the buckle seat 4 are fixedly connected to the limiting baffle 5, which can prevent the buckle seat 4 from slipping off during the sliding process, and the slider block 2 and the buckle seat 4 are connected to each other by a buckle structure 6. Therefore, when the doctor adjusts the hand rest 1 to a suitable position, it can be fixed by this structure to prevent displacement.

[0038] The buckle structure 6 includes a fixing plate 14 arranged in the cavity of the buckle seat 4, and a pressing plate 15 is provided on both sides of the fixing plate 14. Specifically, the front and rear parts of both sides of the fixing plate 14 are fixedly connected with dampers 17, and the damper 17 is fixedly connected to the pressing plate 15. The outer sleeve of the damper 17 is provided with a spring 18, and the two ends of the spring 18 are fixedly connected to the pressing plate 15 and the fixing plate 14 respectively. Therefore, the pressing plates 15 on both sides can make a movement close to or away from the fixing plate 14, and in this movement process, the damper 17 and the spring 18 are continuously squeezed and stretched to deform and generate deformation. Force, at the same time, the pressing plate 15 passes through the cavity and extends to the outside thereof, which allows the doctor to directly operate the above steps outside the buckle seat 4. At the same time, the bottom ends of the pressing plates 15 on both sides are fixedly connected to the sides close to each other with a latch 16. When the damper 17 and the spring 18 are stretched, the latch 16 passes through the cavity and engages with the rack 3. When the doctor manipulates the above-mentioned pressing plate 15, the latch 16 will move with the pressing plate 15, gradually disengaging from the engagement with the rack 3 until it is completely disengaged from the engagement with the rack 3. At this time, the doctor can slide the position of the buckle seat 4 relative to the slide block 2, and then adjust the position of the hand rest 1.

[0039] Next, the outer cylinder 7 is positioned below the slider block 2. Specifically, the bottom end of the snap seat 4 is fixedly connected to a bearing portion 23, which is in bearing connection with the top of the outer cylinder 7. The bottom end of the outer cylinder 7 is fixedly connected to a lifting block 8. A threaded hole 19 is formed in the middle of the lifting block 8. Extensions 20 are fixedly connected to the front and rear ends and both sides of the lifting block 8. The extensions 20 are fixedly connected to the bottom end of the outer cylinder 7.

[0040] At the same time, the inner cylinder 9 is provided with a lifting slot 24 for cooperating with the extension 20 of the lifting block 8. The lifting block 8 is located inside the inner cylinder 9, and the relative sliding of the inner cylinder 9 and the outer cylinder 7 is achieved by passing the extension 20 through the lifting slot 24. In addition, a screw 10 is provided in the inner cylinder 9. Specifically, the top and bottom ends of the inner cylinder 9 are fixedly connected to the cylinder cover 21, and the screw 10 is rotatably connected to the cylinder cover 21. The lifting block 8 is threadedly connected to the screw 10 through the threaded hole 19. Therefore, when the screw 10 is rotated, the lifting block 8 is affected by the threaded connection between the threaded hole 19 and the screw 10 and moves up and down on the screw 10, finally realizing the lifting and lowering of the outer cylinder 7 relative to the inner cylinder 9, thereby adjusting the height of the hand rest 1. When the screw 10 stops, the lifting block 8 provides support force through the thread of the screw 10 to complete the fixed connection.

[0041] In order to provide driving force for the rotation of the above-mentioned screw rod 10, the utility model is fixedly connected to the bottom end of the inner cylinder 9 on the fixing seat 11; a motor 12 is provided below the screw rod 10, and the output shaft of the motor 12 passes through the fixing seat 11 and the cylinder cover 21 and is fixedly connected to the screw rod 10, and a motor seat 22 is fixedly connected to the motor 12, and the motor seat 22 is fixedly connected to the bottom end of the fixing seat 11. When the motor 12 is powered on, it can drive the screw rod 10 to rotate. At the same time, the fixing seat 11 can be connected to the corresponding position of the bed to support the entire equipment. This connection can be a snap, adhesive, thread or welding.

[0042] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
