Problems solved by technology

[0004] First, the reflex hemostatic clip of the clip applicator is used to clamp the blood vessel, but how much force the surgical robot pulls on the clip applier, if the occlusal part is too tight, it will affect the blood vessel and damaged tissue, and if the occlusal force is insufficient, the blood vessel cannot be clamped;

Embodiment 1

[0038] Example 1: An implementation of the flexible connection of the extension part:

[0039] The invention discloses a clip applier for a surgical robot, such as Image 6 As shown, it includes an elongation part 4, an articulation part 5 located at both ends of the elongation part, and a driving end 2. A movable rod is arranged inside the elongating part 4, and the driving end 2 drives the articulating part through the movable rod to perform an opening and closing command. In the prior art, the movable rod is in a rigid state, and when in use, excessive movement of the movable rod will lead to excessive occlusion of the occlusal part and damage blood vessels.

[0040] Therefore, the present invention improves it, such as Figure 21 , the movable rod includes a first movable rod 601 and a second movable rod 602, and the first movable rod 601 and the second movable rod 602 are clamped to limit the first movable rod and the second movable rod to move only relative to the axial...

Embodiment 2

[0045] Embodiment 2: the second implementation mode of the flexible connection of the extension part;

specific Embodiment 1

[0046] Specific embodiment 1: This embodiment discloses a flexible clip applier for a surgical robot, which includes an elongated part 4 and an articulating part and a driving end 2 located at both ends of the elongated part. The internal tension transmission device controls the opening and closing of the occlusal part. The pliers head includes a first occlusal part 501 and a second occlusal part 502 hinged to the first occlusal part. respectively provided with a snap connection part 503, such as Figure 17 As shown, the two occlusal joints are respectively provided with pull grooves 504, and the tension transmission device can be a movable rod 403. Under normal circumstances, the surgical robot transmits power to the driving end, and the driving end drives the occlusal part to open and close, but due to the operation of the robot The doctor is operating remotely and cannot sense the occlusal force of the occlusal part. Therefore, during operation, the occlusion of the clip ap...

Abstract

The invention discloses pincers for a surgical robot and belongs to the field of medical instruments. The pincers include an extension part, clamping parts positioned at both ends of the extension part and a driving end; movable rods are arranged in the extension part and comprise the first movable rod and the second movable rod, the first movable rod is fixedly connected to the driving end and moves through the driving end, multiple limiting columns used for driving hemostatic clips to move forwards are arranged on the side face of the first movable rod, a pulling column used for driving theclamping parts to be opened and closed are arranged at the tail end of the second movable rod, a movable piece is arranged on the side face of the first movable rod, and the second movable rod is provided with a movable cavity and a movable opening which makes the movable cavity communicated with the exterior; the movable piece stretches deep into the movable cavity from the movable opening and can reciprocate along the movable opening, third springs are arranged at the bottoms of the movable piece and movable cavity, and when the movable piece is positioned at the leftmost end of the movableopening, the third springs stay at a slack state.

Description

technical field [0001] The invention relates to the field of medical supplies. Background technique [0002] The hemostatic clip is a device used clinically to clamp blood vessels. The current hemostatic clip clamp is usually single-shot, and can only clamp one hemostatic clip at a time. After the hemostatic clip clamps the blood vessel, the hemostatic clip needs to be reinstalled. [0003] The publication number is CN106037866A, which discloses a hemostatic clip applicator, which can be used multiple times. With the development of surgical robots, it is necessary to install medical equipment on the surgical robot for use, such as electric knife and surgical scissors. Clip applier is a surgical instrument that needs to be frequently used in minimally invasive surgery, but now there are many problems that need to be solved when clip applier is installed on the surgical robot: [0004] First, the reflex hemostatic clip of the clip applier is used to clamp the blood vessel, bu...
