Problems solved by technology

However, in this operation, enterobiliary anastomosis stents are placed in the duodenum. Endoscopic ultrasonography needs to pass through the cardia, stomach and pylorus to reach the duodenum for stent placement. The operation is difficult and the learning curve is long. The promotion of endoscopists limits the development of this technique

Abstract

The invention relates to the field of medical instruments, in particular to an anastomosis device which comprises a first support and a second support; the first support is provided with a first channel; the second support is provided with a second channel and connected with the first support; the second support is located outside the first channel, and the first channel is communicated with the second channel; or at least part of the second support is contained in the first channel. The anastomosis device is small in structural size and can be conveniently arranged in an imbedding device, so that the use difficulty can be reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an anastomosis device. Background technique [0002] Gallstones can enter the common bile duct through the cystic duct and become common bile duct stones. The stones of the common bile duct are incarcerated in the ampulla through the sphincter of Oddi and cause pancreatitis, which is called biliary pancreatitis. Gallbladder-duodenal fistula or gallbladder-colic fistula are caused. Large stones enter the intestinal tract through the fistula and cause intestinal obstruction, which is called gallstone ileus. Gallstones and long-term inflammatory stimulation can induce gallbladder cancer. [0003] At present, the treatment of gallstones can be treated by removing the gallbladder, but there are the following disadvantages in removing the gallbladder: 1. It is easy to cause indigestion and reflux gastritis; 2. The problem of bile duct damage after cholecystectomy; 3. Gallbladder remo...
