Suture clip and releasing method thereof

Abstract

The invention discloses a suture clip and a releasing method thereof. The suture clip comprises at least three central symmetric engaged needle claws, each engaged needle claw comprises a needle tip, a needle body and a tail, the tails of the two adjacent engaged needle claws are connected through a section of arc-shaped spring, all sections of the arc-shaped springs are connected end to end to form a ring, in the free state, the needle tips of all the engaged needle claws point to the center point of the ring, but the needle tips of all the engaged needle claws do not make contact. According to the technical scheme, the needle tips go deep into tissue, the tissue surrounding the surface of a wound is captured actively, the wound with the large area is closed, the tailless end cocks after clipping, and other surgical operation is not affected, the large wound can be sutured rapidly at a time, the structure is reliable, releasing is convenient, and clamping is firm and accurate.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a suture clip used in conjunction with an endoscope and a release method, which are used for suturing surgical wounds under the endoscope to stop bleeding or prevent delayed bleeding. Background technique [0002] With the development of endoscopic technology and other related technologies, endoscopic hemostasis has become the first choice for the treatment of gastrointestinal bleeding. Currently commonly used endoscopic hemostasis methods include laser coagulation, electrocoagulation, local injection of drugs to stop bleeding, drug spraying and hemostatic clip clamping. Among them, hemostatic clip clipping method has become the most effective non-surgical treatment of gastrointestinal bleeding due to its characteristics of small trauma, fast hemostasis, low incidence of rebleeding, few complications, and definite curative effect. . However, when the gastrointestinal bleeding or ...

AI Technical Summary

Problems solved by technology

However, when the gastrointestinal bleeding or postoperative wound area is large, it is often necessary to use multiple hemostatic clips combined with nylon rope for suturing, which not only prolongs the operation time and increases the difficulty of the operation, but also increases the operation cost and increases the risk for patients. pain
