Tissue clip capable of continuously releasing and clamping

Abstract

Provided is a tissue clip capable of continuously releasing and clamping. The clip is characterized in that the tissue clip is cut by laser cutting in one time, and the tissue clip finally shapes through heat treatment and polishing and other processes. The clip has good clamping force and superelasticity. The tissue clip comprises a tissue clamp, a limiting ring, and a conveying system. After thetissue clamp clamps a tissue, the tissue clamp can be freely disconnected with a subsequent tissue clamp, and the disconnected tissue clamp would not separate from a tissue. The tissue clip is made of nickel titanium tubing, and has memory and superelasticity.

Description

technical field [0001] The invention relates to a hemostatic clip, in particular to a tissue clip capable of continuous release and clamping, which belongs to medical equipment. Background technique [0002] Endoscopic metal clip hemostasis is one of the more widely used hemostasis methods. Skilled metal clip operation in appropriate cases can effectively stop bleeding and prevent rebleeding, reduce adverse reactions, and greatly improve the safety of endoscopic treatment of gastrointestinal bleeding [0003] sex and cure rates. The hemostatic mechanism of the metal hemostatic clip is the same as surgical vascular ligation or suturing. It is a physical and mechanical method that uses the mechanical force generated when the hemostatic clip is closed to ligate the surrounding tissue and bleeding blood vessels, thereby closing the bleeding blood vessels to prevent bleeding. Cut off the blood flow to achieve the purpose of hemostasis, suitable for hemostatic treatment of non-va...

AI Technical Summary

Problems solved by technology

The hemostatic clip uses many matching parts, which is difficult to manufacture, and the assembly reliability and stability are poor, and it is easy to loosen before use

[0007] In addition, the existing hemostatic clips are generally made of metal materials. After the hemostatic clips are clamped, they can fall off on their own as the wound heals and are excreted along the digestive tract.

Because it needs to pass through the digestive tract in the body, it will inevitably cause damage to the human body, and for some people, it is also prone to danger caused by hemostatic clip retention

[0008] Moreover, the currently used hemostatic clip can only achieve hemostasis on one site each time, and needs to be replaced with a new hemostatic clip after each use, which is a waste of time and equipment. Therefore, it is necessary to have a skill to realize the function of the original hemostatic clip, which is simple and convenient. Devices capable of releasing multiple hemostatic clips
