Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a gallbladder drainage device. Background Art

[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 main treatment for gallstones with acute cholecystitis. With the rapid economic and social development of China 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 have poor tolerance to general anesthesia and long-term surgery. On this basis, local anesthesia cholecystostomy, percutaneous transhepatic gallbladder puncture and drainage (PTCD), and endoscopic retrograde gallbladder drainage (ERGD) have been derived. Among them, ERGD has less trauma, significant efficacy, and rapid recovery, and is more suitable for patients with gallstones and acute cholecystitis with ascites and cirrhosis.

[0003] At present, intra-biliary drainage tubes are used clinically for gallbladder bile drainage. Commonly used intra-biliary drainage tubes include linear, single pigtail and double pigtail types, among which single pigtail intra-biliary drainage tubes are the most commonly used. The utility model patent with publication number CN204017095U discloses an anti-reflux bile duct drainage tube. Although the above-mentioned drainage tube can effectively prevent the adhesion of bile and food residues, only side holes are provided at both ends, and no side holes are provided on the tube body. When the head end of the drainage tube is inserted into the gallbladder, the intra-biliary drainage tube has no drainage effect on the hepatic bile duct bile, thereby losing the function of the intra-biliary drainage tube. In addition, the current drainage tube cannot dilute the remaining bile in the gallbladder, so that the remaining bile in the gallbladder cannot be discharged well. Utility Model Content
