Embodiment 1

[0043] Example 1: The connection part between the drive end and the robot (fixture part):

[0044] This embodiment discloses a hemostatic clip applier and the structure of the joint between the hemostatic clip applier and the surgical robot. The clip applier includes an elongated part 4 and occlusal parts 5 connected to both ends of the elongated part 4 And the driving end 2, the driving end 2 controls the opening and closing of the occlusal part through the elongation part, and delivers the hemostatic clip inside the elongation part to the occlusal part 5 and further clamps the blood vessel. Such as figure 1 As shown, the driving end is connected to the execution end of the surgical robot, and the execution end is a substrate 1. The surgical operator operates the surgical robot remotely (such as the operating room next to the operating room or in another city) to perform surgery. The robot controls the clip applier through the driving end 2 to make corresponding instructions...

Embodiment 2

[0054] Example 2: An implementation of the flexible connection of the extension part:

[0055] The invention discloses a clip applier for a surgical robot, such as Figure 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.

[0056] 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 axia...

Abstract

The invention discloses a fixing device of hemostasis clip applying pliers, and belongs to the field of medical instruments. The fixing device comprises a basic plate, a driving end and a position clamping assembly. An installing groove and a moving groove are formed in the basic plate; the driving end is connected with the extending portion of the hemostasis clip applying pliers, an engaging portion is connected to the tail end of the extending portion, and used for closing a hemostasis clip, and the driving end is cylindrical and can be installed in the installing groove in the basic plate;two position clamping grooves are formed in the side face of the driving end; the position clamping assembly comprises a first clamping portion and a second clamping portion, wherein the first clamping portion and the second clamping portion can extend into the two position clamping grooves of the driving end respectively, and are connected through a connecting strip, and an operating assembly ishinged to the second clamping portion and controls the first clamping portion and the second clamping portion to be clamped into the position clamping grooves and extend out from the position clampinggrooves through force of reciprocation.

Description

technical field [0001] The invention relates to the field of surgical equipment. 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] In some cases, there are also some multi-shot types, which can shoot multiple hemostatic clips at the same time. [0004] The hemostatic clip applier is a device used for radiation hemostatic clips, which is particularly useful in minimally invasive surgery, and medical robots are the development direction for minimally invasive surgery, so it is necessary to use multiple hemostatic clip appliers In medical robots, this kind of clip applier is usually controlled by the gun handle, and the end of the medical robot is driven by rotation force. How to design the clip applier on the medica...
