[0002] The choledochoscope is a new examination method for treating or diagnosing biliary tract diseases. The choledochoscope includes an oral choledochoscope, a percutaneous transhepatic choledochoscope, and an intraoperative and postoperative choledochoscope, and is an ideal examination method for diagnosing bile duct diseases. Clinical applications include the diagnosis of benign and malignant diseases of the common bile duct (observation and biopsy), and the observation and treatment of common bile duct stones (crushing stones with an alligator forceps and retrieving stones with a basket-shaped lithotriptor, etc.).

[0003] When the existing electronic choledochoscope is in use, there are many steps in the connection between its structures, resulting in a large amount of time-consuming during on-site assembly. Moreover, in the later disinfection and sterilization work, it is difficult to remove bacteria from some corners, so disassembly is required. Content of the Utility Model
