Description

technical field [0001] The invention relates to the technical field of medical devices, and more particularly, to a clinical stone extraction device for hepatobiliary surgery. Background technique [0002] Hepatolithiasis is a common and frequently-occurring disease. It refers to stones that occur in any part of the hepatobiliary system. According to the chemical composition of the stones, hepatolithiasis can be divided into cholesterol stones, bile pigment stones and mixed stones. Treatment methods include surgical lithotripsy, western medicine therapy, and traditional Chinese medicine. [0003] Surgical treatment is the main treatment method for intrahepatic bile duct stones. Surgical methods can be selected according to the current situation and the location of the stones, such as bile duct stone removal, bile duct and intestinal anastomosis and drainage, and partial hepatectomy. At present, the commonly used stone extraction devices in clinic are mostly in the shape of ...
