Problems solved by technology

With the development of endoscopic technology, transoral choledochoscope can enter the body through the mouth to perform non-invasive visual stone removal. However, in the existing choledochoscope stone removal device, the balloon is prone to eccentricity after blowing up, which is not conducive to surgery. carry out

Abstract

The invention provides a calculus removing balloon and device under a choledochoscope, and relates to the technical field of medical equipment. The calculus removing balloon under the choledochoscope comprises a balloon catheter and a balloon body; the balloon body is provided with an opening end, the opening end is in sealed connection with the outer surface of the balloon catheter, and an expansion cavity is formed between the balloon body and the outer surface of the balloon catheter; the end face of the balloon catheter is located in the expansion cavity, and the balloon catheter is used for discharging gas or liquid in the gas-liquid device into the expansion cavity. According to the calculus removing balloon under the choledochoscope, due to the fact that only one opening end of the balloon body is connected with the outer surface of the balloon catheter in the sealed mode, in the balloon body expansion process, the end face of the balloon catheter is located in the expansion cavity, the end, away from the opening end, of the expansion cavity is not limited, and the balloon body can adjust the expansion direction of itself; therefore, the problem that a conventional balloon catheter is eccentric is effectively avoided. In addition, the balloon body can have a larger length size, and the expansion effect is better.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a stone removal balloon and a device under a choledochoscope. Background technique [0002] Cholelithiasis refers to a disease in which stones occur in the biliary system, including the gallbladder or hepatic bile ducts. It mainly includes gallbladder stones, common bile duct stones, intrahepatic and extrahepatic bile duct stones, among which there are many clinical treatment methods for common bile duct stones and extrahepatic bile duct stones, and the technology is mature, and stone removal can be performed from laparoscopy to endoscopy. For gallbladder stones and intrahepatic bile duct stones, due to the structural limitations of the cystic duct and intrahepatic bile duct, the treatment options are relatively limited. [0003] At present, the main treatment methods are laparoscopic resection or percutaneous hepatic cholangioscopy to remove lithotripsy. A small numbe...
