A structure-optimized digestive tract hemostatic clip

Abstract

The invention discloses a digestive tract hemostasis clamp of an optimized structure. The clamp comprises a left clamping rod and a right clamping rod of the hemostasis clamp. A left clamping head anda right clamping head are molded at the top of the left clamping rod and the top of the right clamping rod respectively, a slot is formed in the left clamping rod, the right clamping rod is insertedinto the slot of the left clamping rod, a bolt penetrates through the left clamping rod and the right clamping rod to be in screw joint with a limiting nut, and the limiting nut abuts against the leftclamping rod; a vertical pin shaft is inserted into the tail of the right clamping rod; limiting sleeves are fixedly inserted into the two ends of the pin shaft and are exposed, and the limiting sleeves abut against the upper and lower end faces of the right clamping rod; horizontal cutting grooves are formed in the two opposite outer walls at the two ends of the pin shaft; an arc connecting plate is fixedly arranged at the tail of the left clamping rod, an arc clamping groove opposite to the pin shaft is formed in the outer end of the connecting plate, and a rectangular pulling block is fixedly arranged at the upper end of the pin shaft. A micro hemostasis clamp inside the digestive tract is improved, and recycling of the micro hemostasis clamp in second operation is achieved conveniently.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a structure-optimized digestive tract hemostatic clip. 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 clips. Among them, the hemostatic clip method has become the most effective non-surgical treatment of gastrointestinal bleeding due to its characteristics of less trauma, faster hemostasis, lower incidence of rebleeding, fewer complications, and definite curative effect. However, the existing hemostatic clips in the digestive tract, because of their small size, cannot be installed with springs to realize the elastic clamping of the hemostatic cl...

AI Technical Summary

Problems solved by technology

However, the existing hemostatic clips in the digestive tract are small in size, so springs cannot be installed to realize the elastic clamping of the hemostatic clips, so the hemostatic clips are usually designed by clamping and then fixed to death, thus requiring a second operation Remove the hemostatic clip, but in the second operation, due to factors such as the fixed design of the hemostatic clip and the volume of the hemostatic clip, the recovery of the hemostatic clip is more troublesome
