A flexible top end of the intestinal polyp ligation device

Abstract

The invention relates to the technical field of ligation devices, and discloses a ligation device for intestinal polyps with a bendable tip, which includes a protective casing of a firing part and an elastic ligation ring. A structural sleeve is arranged on one side of the protective casing of the firing part. The sleeve includes a rigid connection sleeve, a flexible outer tube and a distal structural tube. A ligation trigger is movable in the center of the flexible outer tube and the distal structural tube. The ligation trigger is composed of a trigger head and a trigger link. By setting the flexible outer tube that can be bent freely, due to the flexibility of the flexible outer tube, both the flexible outer tube and the limiting groove can be bent to a certain extent under the action of external force, so that the flexible outer tube can be It can be bent according to the required angle to adapt to the complex intestinal environment, and the top of the ligation device can be precisely fitted to the polyp, and the free bending top makes it unnecessary for medical staff to operate. The large use space effectively reduces the difficulty of operation, making the ligation device more usable and universal.

Description

Technical field [0001] The present invention relates to the field of latch technology, specifically a top bendable intestinal polyp lash device. Background [0002] Intestinal polyps are mucosal bulge-like lesions formed due to local mucosal hyperplasia and hypertrophy caused by chronic inflammation of the mucous membranes, and can also be adenomas or hamartomas. It is mainly seen in the large intestine, while the small intestine is rare, and the intestinal polyps are more common, and their incidence can increase with age. Some patients may have clinical manifestations such as blood in the stool, abdominal pain, and diarrhea. Most of the polyps are benign, usually surgical removal, with the development of medical technology, there is a special ligation ring to tie up the lesion site, so that the arteries at the lesion site are blocked by the ligation, in order to stop the blood supply of the intestinal polyps, so that the intestinal polyps necrosis, atrophy, shedding, so as to ac...

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
