Technical Field

[0001] This utility model relates to the field of ligation clip technology, and in particular to an absorbable ligation clip. Background Technology

[0002] A ligation clip is a surgical instrument used primarily to ligate blood vessels or other channels to prevent the flow of blood or other fluids. It is typically made of metal or plastic and has clamping and fixing functions. Ligation clips are widely used in various surgical procedures, especially in abdominal surgery, gynecological surgery, and cardiovascular surgery.

[0003] In existing technologies, ligation clips are used to ligate the patient's wound during minimally invasive surgery. Some ligation clips need to be placed inside the patient's body. To reduce the risk of rejection, absorbable materials are used to make the ligation clips. However, the adhesion of absorbable ligation clips is not stable enough, which can affect the ligation effect. Therefore, this invention designs an absorbable ligation clip. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, during the operation of minimally invasive surgery, ligation clips are needed to ligate the patient's wound. Some ligation clips need to be placed inside the patient's body. In order to reduce the rejection phenomenon in the patient's body, absorbable materials are needed to make ligation clips. However, the adhesion effect of absorbable ligation clips is not stable enough, which will affect the ligation effect. Therefore, an absorbable ligation clip is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An absorbable ligation clip includes a first clamping arm, an elastic connecting strip, and a second clamping arm. One end of the elastic connecting strip is fixedly connected to the first clamping arm, and the other end of the elastic connecting strip is fixedly connected to the second clamping arm. A column is rotatably connected to the side wall of the first clamping arm, and the end of the column extends to the outside of the first clamping arm and is fixedly connected to a sleeve block. A slot is formed on the inner wall of the sleeve block, and the side wall of the second clamping arm extends to the inner wall of the sleeve block located in the slot.

[0007] Preferably, an extension strip is fixedly connected to the side wall of the second clamping arm, and an extension groove is provided on the inner wall of the first clamping arm, with the extension strip extending to the inner wall of the extension groove.

[0008] Preferably, a positioning block is fixedly connected to the side wall of the extension strip, and the first clamping arm is provided with a positioning groove on the inner wall of the extension groove, and the positioning block is inserted into the inner wall of the positioning groove.

[0009] Preferably, the sidewall of the positioning block is provided with a plurality of anti-slip protrusions, and the upper surface of the anti-slip protrusions is set as an arc surface.

[0010] Preferably, a retaining ring is fixedly connected to the end of the column located inside the first clamping arm, and the retaining ring is slidably disposed on the inner wall of the first clamping arm.

[0011] Preferably, the inner wall of the first clamping arm has a cavity, and an arc-shaped elastic bar is fixedly connected to the inner wall of the first clamping arm in the cavity. The side wall of the arc-shaped elastic bar is provided with a plug, and the side wall of the column is provided with a slot, and the plug matches the slot.

[0012] Compared with the prior art, the present invention provides an absorbable ligation clip, which has the following beneficial effects:

[0013] 1. This absorbable ligation clip, by pressing the second clamping arm to extend the extension strip into the extension groove of the first clamping arm, bends the elastic connecting strip, and then rotates the column to make the sleeve block fit on the side wall of the second clamping arm, so that the second clamping arm is stably pressed and set on the side wall of the first clamping arm, which can improve the ligation clamping effect of the ligation clip.

[0014] 2. This absorbable ligation clip can push the insert block to extend to the inner wall of the slot by rotating the sleeve block and then bouncing in an arc. This can keep the sleeve block stable after rotation and further improve the ligation effect of the ligation clip. The retaining ring can improve the smoothness of the column rotation.
