Endoscopic duodenum-jejunum bypass weight-reducing bracket and using method thereof

Abstract

The invention relates to an endoscopic duodenum-jejunum bypass weight-reducing bracket and a using method thereof. The endoscopic duodenum-jejunum bypass weight-reducing bracket comprises an upper bracket, a first membrane pipe, a lower bracket and a second membrane pipe which are sequentially connected from top to bottom, wherein the upper bracket is gradually contracted from top to bottom, and cooperates with the shape of the gastric antrum; a plurality of titanium clip fixing rings are uniformly arranged on the outer side of the upper edge of the upper bracket in the circumferential direction; and the lower bracket is gradually expanded from top to bottom and cooperates with the shape of the duodenal ampulla. According to the endoscopic duodenum-jejunum bypass weight-reducing bracket disclosed by the invention, pylorus, namely the normal anatomical structure is sufficiently utilized for fixing the bracket, and the titanium clip fixing rings cooperate with the titanium clips to fix the bracket, so that the fixing of the bracket is more stable, and the possibility of bracket shifting can be reduced; and besides, the stimulation of a conventional bracket agnail to the duodenal ampulla mucosa is avoided, occurrence of complication including abdominal pain, disgusting and the like is reduced, and further popularizing endoscopic duodenal -jejunal bypass for treating obesity is facilitated

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an endoscopic duodenum-jejunum bypass weight-reducing bracket and a use method thereof. Background technique [0002] In recent years, the obese population in the world has been increasing, and about 4 million people die each year from various complications caused by obesity, such as diabetes, high blood pressure, and fatty liver. The absolute number of obese people in China has reached more than 89.6 million, ranking first in the world. Obesity-related complications have brought heavy economic burdens and health damages to society and patients. At present, the treatment methods for obesity mainly include: lifestyle adjustment, drug therapy and bariatric surgery, but generally speaking, the effect of the first two is not ideal, while bariatric surgery is relatively effective, but has potential serious complications.

Problems solved by technology

The upper edge of the current stent is fixed on the duodenal bulb by using barbs. On the one hand, this fixing method is extremely unstable and easily causes displacement.

On the other hand, during the process of intestinal peristalsis, the barbs constantly rub against the intestinal mucosa, which can cause discomfort such as abdominal pain and nausea in patients.
