Intestinal polyploop ligature device with bendable top end

Abstract

The invention relates to the technical field of loop ligature devices, and discloses an intestinal polyp loop ligature device with a bendable top end. The intestinal polyp loop ligature device comprises a percussion part protection shell and an elastic loop ligature ring. A structural sleeve is arranged on one side of the percussion part protection shell; the structural sleeve comprises a rigid connecting sleeve, a flexible outer tube and a far-end structural tube; a loop ligature trigger is movably arranged in the center of the flexible outer tube and the far-end structure tube; the loop ligature trigger is composed of a trigger head and a trigger connecting rod. The flexible outer tube capable of being freely bent is arranged; the flexible outer tube has flexibility, and the flexible outer tube and the limiting groove can be bent to a certain degree under the action of external force, so that the flexible outer tube can be bent according to a required angle to adapt to a complex intestinal environment;the top end of the loop ligature device can be accurately attached to a polyp part, through the top end capable of being freely bent, a large use space is not needed when medical staff operate the loop ligature device, the operation difficulty is effectively reduced, and the usability and universality of the loop ligature device are higher.

Description

technical field [0001] The invention relates to the technical field of ligation devices, in particular to a ligation device for intestinal polyps with a bendable tip. Background technique [0002] Intestinal polyps are mucosal bulge-like lesions formed due to local mucosal hyperplasia and hypertrophy caused by chronic mucosal inflammation, and can also be adenomas or hamartomas. It is mainly seen in the large intestine, while the small intestine is relatively rare, and intestinal polyps are more common, and its incidence can increase with age. Some patients may have clinical manifestations such as blood in the stool, abdominal pain, and diarrhea. Most polyps are benign, and are usually removed surgically. With the development of medical technology, a special ligation ring has been used to ligate the lesion, so that the artery of the lesion is blocked by the ligation, so as to stop the bleeding. The blood supply of intestinal polyps makes intestinal polyps necrosis, atrophy...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an intestinal polyp ligation device with a bendable tip, which has the advantages of being able to rotate in multiple directions, requires a small operating space, has high ligation accuracy, and is easy to operate, and solves all the problems. It requires a large operating space, it is difficult to operate in multiple directions, and it is not suitable for relatively narrow intestinal space
