Problems solved by technology

[0003] In some cases, there are also some multi-shot types, which can shoot multiple hemostatic clips at the same time, but how to advance the hemostatic clip along the clamp tube or the extension is a crucial issue that affects the performance of the clip applier
[0004] The publication number is CN106037866A, which discloses a hemostatic clip applicator, which can be used multiple times. The principle of advancing the hemostatic clip is as follows: the hemostatic clip is respectively provided with two limit posts, and the clip 3 is provided with 31 pairs of limit bars. One limit column of the hemostatic clip is used to limit the position, and the other uses the positioning bar of the push splint 92 to limit the position of the other limit post of the hemostatic clip. When in use, push the splint forward, and further push the hemostatic clip forward through the positioning bar , in this case, what pushes the hemostatic clip forward is the force received by the two limit posts of the hemostatic clip. When advancing, the hemostatic clip is easily deformed, which further affects the closing and clamping effect of the hemostatic clip
At the same time, the existing push splint is easy to deform when it is advancing, especially when it is applied to a surgical robot, because the push splint advances slowly, the push splint is easy to bend and deform, and then affects the effect of advancing the hemostatic clip

Embodiment 1

[0041] Example 1: Improved implementation of the extension:

[0042] A hemostatic clip applier for minimally invasive surgery, comprising an extension part 4, an articulation part 5 located at both ends of the extension part, and a driving end 2, the driving end controls the opening and closing of the articulation part through the extension part, and the extension part is placed inside A plurality of hemostatic clips 404 distributed along the axial direction of the elongated part, the hemostatic clip includes a first clip arm and a second clip arm and a joint between the first clip arm and the second clip arm, the first clip arm and the second clip arm The top of the second clamp arm is provided with a limit protrusion (such as Figure 10 hemostatic clip), wherein, the position-limiting protrusions of the first clamp arm and the second clamp arm of the present invention are different from the existing ones, and their positions should be set at the extreme ends of the first cla...

Embodiment 2

[0051] Example 2: An implementation of the flexible connection of the extension part:

[0052] 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.

[0053] 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...

Abstract

The invention discloses a minimally invasive surgery hemostatic clip applier, and belongs to the field of medical instruments. The minimally invasive surgery hemostatic clip applier comprises an extension part (4), a meshing part (5) and a driving end (2), wherein the meshing part (5) and the driving end (2) are located at the two ends of the extension part; the driving end controls opening and closing of the meshing part through the extension part, and a hemostatic clip cavity (402) used for advancing of a hemostatic clip is formed in the middle in the extension part; the cross section of thehemostatic clip cavity is rectangular, and a movable rod cavity (401) communicated with the hemostatic clip cavity is formed in the side face of the hemostatic clip cavity; the movable rod cavity islocated in the middle of the hemostatic clip cavity; the movable rod cavity (401) is internally provided with a movable rod (403), and a limiting column (4031) is arranged on the movable rod; the limiting column is used for limiting the joint of the hemostatic clip; the upper portion and the lower portion of the movable rod are both provided with a clamping strip (4034); a first clamping groove (411) and a second clamping groove (421) which are matched with the clamping strips are formed in the upper side and the lower side of the movable rod cavity respectively.

Description

technical field [0001] The invention relates to the field of medical 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, but how to advance the hemostatic clip along the clamp tube or the extension is a crucial issue that affects the performance of the clip applier. [0004] The publication number is CN106037866A, which discloses a hemostatic clip applicator, which can be used multiple times. The principle of advancing the hemostatic clip is as follows: the hemostatic clip is respectively provided with two limit posts, and the clip 3 is provided with 31 pairs of limit bars. One limit column of ...
