Problems solved by technology

Manual suture anastomosis is an anastomosis method with a long history. It is completed by hand suturing with silk thread or absorbable thread. The operation is cumbersome, the anastomosis time is long, and there is a certain incidence of anastomotic complications. Developed regions are still the most important method of gastrointestinal anastomosis
The stapler anastomosis method is to use a stapler to complete gastrointestinal anastomosis. The anastomosis method is simple and the anastomosis time is short, but the price of the stapler is high, and metal foreign objects will remain in the abdominal cavity for life after anastomosis
Due to the shortcomings of these anastomotic methods and equipment, complications such as anastomotic leakage and anastomotic stenosis are unavoidable.

Embodiment Construction

[0009] The gastrointestinal anastomosis bracket according to the present invention comprises a bracket body made of human body acceptable and degradable material. The openings are small, the larger end opening 2 has a shape and size adapted to the lumen of the stomach, and the smaller end opening 3 has a shape and size adapted to the intestinal cavity.

[0010] The human body acceptable and degradable material used in the present invention, such as polylactic acid.

[0011] For anastomosis, purse-string sutures are first performed at the openings of the stomach and intestines, and then the larger end 2 opening is placed into the gastric cavity, the purse-string is tied, the stomach wall is fixed in the middle of the bracket, and the smaller end opening 3 Put it into the intestinal lumen, tie the purse string, fix the intestinal wall in the middle part of the bracket 1, and make the stomach wall and the broken end of the intestinal wall contact in the middle part of the bracket...

Abstract

The invention relates to a gastrointestinal anastomosis stent, comprising a stent main body made of degradable material which is acceptable by people. The middle of the stent main body is tubular, and two ends of the stent main body are open and increase gradually like a trumpet; one opening is big and the other opening is small; the opening at the big end is in a shape and a size which are suitable for the lumen of the stomach; and the opening at the small end is in a shape and a size which are suitable for the lumen of the intestine. The gastrointestinal anastomosis stent can simplify anastomosis process, shorten anastomosis time and reduce complicating diseases after the operation, and the stend is low in cost and wide in application range.

Description

(1) Technical field [0001] The invention relates to a bracket for gastrointestinal anastomosis, which can simplify gastrointestinal anastomosis and improve the safety of gastrointestinal anastomosis. (2) Technical background [0002] At present, the methods of gastrointestinal anastomosis mainly include manual suture anastomosis and stapler anastomosis. Manual suture anastomosis is an anastomosis method with a long history. It is completed by hand suturing with silk thread or absorbable thread. The operation is cumbersome, the anastomosis time is long, and there is a certain incidence of anastomotic complications. Developed regions are still the main method of gastrointestinal anastomosis. The stapler anastomosis method uses a stapler to complete gastrointestinal anastomosis. The anastomosis method is simple and the anastomosis time is short, but the price of the stapler is high, and metal foreign bodies will remain in the abdominal cavity for life after anastomosis. Due t...
