Ligation clip

Abstract

The invention provides a ligation clip. The ligation clip comprises a first arc-shaped clip arm and a second arc-shaped clip arm. The free end of the first arc-shaped clip arm is provided with a clamping hook. The free end of the second arc-shaped clip arm is provided with a clamping head. The first arc-shaped clip arm is provided with a cylindrical clamping hook clamping body. The second arc-shaped clip arm is provided with two clamping head clamping bodies which are arranged opposite to each other. A clamping body connection circular arc is arranged at the joint of the first arc-shaped clip arm and the second arc-shaped clip arm. The distance between the clamping hook clamping body and the midpoint of the outermost side of the clamping body connection circular arc is the same as the distance between each clamping head clamping body and the midpoint of the outermost side of the clamping body connection circular arc. The diameter of the cylinder of the clamping hook clamping body is equal to the diameter of a cylindrical surface of each clamping head clamping body. The ligation clip can be used for different operation environments; no matter what size of the ligation clip in need is, the ligation clip can be well matched with an instrument as long as the regular design of the ligation clip is followed, optimal clamping force can be obtained, and the ligation clip cannot be damaged in the closing process.

Description

technical field [0001] The invention relates to a surgical medical device, in particular to a clip used for closing blood vessels or tissues during surgical operations, which can be clinically used for anastomosis and ligation of blood vessels and tissues during internal surgical operations. In practical applications, the ligation clip is also commonly referred to as a blood vessel clip, a ligation buckle, a surgical lock clip, a tissue clip, and the like. Background technique [0002] In order to fully expose the surgical field of view during the surgical operation, it is necessary to ligate the broken blood vessels in the incision to prevent bleeding. Hemostasis technology has become one of the cores of basic surgical techniques, and surgical operations on any part of the human body almost without exception involve bleeding and hemostasis. Generally, the broken blood vessel is clamped with hemostatic forceps and then ligated with sutures. This method is cumbersome to oper...

Problems solved by technology

[0003] At present, although the principles of various ligation clips are similar, there is still room for improvement in structure. Specifically, the closing force and reliability of the ligation clips need to be improved.

In addition, there are currently no clear features that can be followed in the structural design of various types of ligature clips. For different types and sizes of ligature clips, special designs need to be made for different use environments. The versatility is not good, an
