External drainage tube for nasal-gallbladder bile

Abstract

The invention discloses an external drainage tube for nasal-gallbladder bile. An elastic loop tube I, an elastic loop tube II, a drainage tube segmentI, a drainage tube segment II, a drainage tube segment III, a drainage tube segment IV are arranged from the top to the bottom successively and communicated with each other. The drainage tube segment I is similarlyin an arc shape, and the arc shape opens towards the elastic loop tube I. The drainage tube segment II is curved, and forms a sigma shape with an end of an arc tube segmentII. The drainage tube segment III is in an arc shape, and the arc shape opens towards an arc tube segment I. The drainage tube segment IV is in a straight line shape. The end part of the elastic loop tube I, elastic loop tube II and arc tube segment II are all provided with bile drainage orifices. The external drainage tube for the nasal-gallbladder bile has five bends, which is conformed to the five physiological bends of a gallbladder cavity (the elastic loop tube I, the elastic loop tube II), a gallbladder tube-a common bile duct (the drainage tube segmentI), the common bile duct-a duodenum (the front part of the drainage tube segment II), the duodenum-a gastric antrum (end part of the drainage tube segment II), a greater curvature of stomach (the drainage tube segment III). The external drainage tube for the nasal-gallbladder bile is good in comfort.

Description

technical field [0001] The invention relates to a bile external drainage tube, in particular to a nasal gallbladder bile external drainage tube. Background technique [0002] Acute cholecystitis is a common and frequently-occurring disease in my country, and gallstones are its main cause. Open cholecystectomy is the traditional treatment for acute cholecystitis. With the development of endoscopic equipment and minimally invasive techniques, laparoscopic cholecystectomy has become the gold standard for the treatment of gallstones. With the rapid development of China's economy and society in the 21st century, population aging has gradually become one of the hot issues in contemporary Chinese society. Elderly patients often have underlying diseases such as hypertension, diabetes, and coronary heart disease, and are resistant to general anesthesia and long-term operations. On this basis, local anesthesia cholecystostomy, percutaneous transhepatic gallbladder drainage (PTCD), an...

AI Technical Summary

Problems solved by technology

However, the application of nasobiliary drainage tube to nasal gallbladder drainage has the following problems: 1. The head end of the nasobiliary drainage tube is a loop, and the side hole is only located in the loop tube at the head end of the drainage tube. It cannot enter the drainage tube, and it is also difficult to enter the gallbladder through the gap between the drainage tube and the cystic duct mucosa, thus losing the drainage effect on the bile in the extrahepatic and extrahepatic bile ducts, and the bile from the hepatic bile duct cannot dilute the inflammatory media in the gallbladder, which is not conducive to Recovery of acute cholangitis and acute cholecystitis after ERCP; 2. The cystic duct is arc-shaped and merges with the common hepatic duct at an acute angle, while the front section of the nasobiliary drainage tube is straight, which does not match the physiological results of the biliary tract. The bile duct drainage tube is easy to compress the cystic duct or cause the gallbladder wall to be pulled and induce abdominal pain symptoms; 3. The tip of the nasobiliary drainage tube is curved, and the tip of the nasobiliary drainage tube is easy to compress the gallbladder mucosa, leading to local hyperplasia and even gallbladder perforation;4 .When flushing the nasobiliary duct, the flushing fluid can only enter the gallbladder, not the bile duct, which is not conducive to the prevention and treatment of postoperative cholangitis and nipple bleeding; If the end of the drainage tube is straightened, the head of the drainage tube can cause damage to the gallbladder, bile duct and intestinal mucosa, and even induce complications such as acute cholecystitis, cholangitis, acute pancreatitis, and bleeding; Occupied in the gallbladder, because the shape does not match the structure of the biliary system, the head of the drainage tube is easy to slip off into the common bile duct, thus losing the drainage effect on the gallbladder bile
