Novel digestive tract hemostatic clamp capable of being repeatedly closed

Abstract

The invention discloses a novel digestive tract hemostatic clamp capable of being repeatedly closed. The novel digestive tract hemostatic clamp comprises a metal chuck, a release component, a conveying component and a handle, wherein the metal chuck comprises a clamping plate and a connector; the connector and a push-pull end of the clamping plate are sleeved into a whole; the push-pull end of the clamping plate and the connector can slide back and forth in a tightening pipe; a wing part is arranged on the clamping plate; a limiting pin is fixed on the front part of the tightening pipe; a concave hole is formed in the front part of the tightening pipe; the release component comprises the content as follows: the front part of a connecting pipe is connected with the rear part of the tightening pipe through a movable buckle; the rear part of the connecting pipe is fixedly connected with a spring pipe; a half-surrounded hole which loses efficacy in relatively large tension is formed in the front part of a connecting rod, and is connected with a fixed pin of the connector; a convex circular truncated cone is arranged on the front part of the connecting rod; a counter bore in the rear part of the connecting rod is fixedly connected with a traction steel wire; the conveying component comprises the traction steel wire, a protective hose and the spring pipe; the spring pipe is provided with a thin-wall conduit in a thermal shrinkage manner; a boosting pipe is fixedly connected with the traction steel wire. The novel digestive tract hemostatic clamp has the characteristics of being simple in structure and reliable to clamp, and is capable of opening and closing for a plurality of times.

Description

technical field [0001] The invention relates to a tissue clamping device for gastrointestinal system, biliary tract system and other body cavities, specifically, it reaches the target bleeding site through the working forceps of the endoscope, and clamps the edges of the wound or incision together And the hemostatic clip that achieves the purpose of hemostasis. Background technique [0002] In clinical medicine, bleeding in the gastrointestinal system, biliary system, vascular system, and other body cavities and hollow organs is a common clinical symptom. At present, hemostasis methods include: spraying drugs, drug injection, laser coagulation, ligation of varicose veins, microwave hemostasis, hemostatic clip hemostasis, etc., but the application of hemostatic clips under the endoscope is due to its small side damage, fast hemostasis speed, high success rate, and complications. It has become the most effective method of non-surgical treatment of acute gastrointestinal bleed...

AI Technical Summary

Problems solved by technology

[0006] The hemostatic clips of the above two open patents can only be closed once, and cannot be opened and closed repeatedly. It is inconvenient to reposition at the target. Once the hemostatic clip is closed, it cannot be opened again.

When the clamped tissue is not suitable, the clip can only be broken off, then exit the delivery system, and then send a new hemostatic clip, which is troublesome to operate and delays the doctor's processing time

In addition, the part of some hemostatic clips left in the body is longer, about 16 mm, which is not suitable for placing in narrow spaces such as the biliary tract, as there is a risk of scratching the tissue wall of the digestive tract, causing perforation and secondary bleeding
