Abstract

The invention provides an electronic choledochoscope which comprises a third channel structure, a third choledochoscope body and a superfine soft tube, wherein a seventh instrument channel for an operable instrument to pass through is formed in the third channel structure, and the third channel structure is provided with a third instrument access port communicated with the seventh instrument channel; an eighth instrument channel for the operable instrument to pass through is formed in the third choledochoscope body, the third channel structure is connected to the third choledochoscope body, and the seventh instrument channel is communicated with the eighth instrument channel; and the superfine soft tube is arranged at one end of the third choledochoscope body, the diameter of the superfine soft tube is smaller than or equal to 3.2 mm, the length of the superfine soft tube is smaller than or equal to 350 mm, and a ninth instrument channel for the operable instrument to pass through is formed in the superfine soft tube, wherein the ninth instrument channel is communicated with the eighth instrument channel. The invention further provides an electronic choledochoscope system. The electronic choledochoscope and the electronic choledochoscope system which are provided by the invention can be used for removing third-level intrahepatic bile duct calculi, cystic duct calculi and the like.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically, to an electronic choledochoscope and an electronic choledochoscope system. Background technique [0002] The human biliary system includes intrahepatic bile ducts, extrahepatic bile ducts and gallbladder. The anatomical structure of the biliary system is like a big tree, which can be thick or thin. For example, there is a thicker common bile duct with a diameter of 6-8 mm; Intrahepatic bile ducts of the first, second and third levels, among which the third level of intrahepatic bile ducts have different shapes and are very thin, with a diameter of only 1-2mm; there is also a pear-shaped gallbladder, with a length of 10-15cm and a width of 3- 5cm, and the cystic duct with a diameter of about 3mm, so the anatomy of the biliary tract is extremely complex. [0003] Among the diseases of the biliary system, the most common one is cholelithiasis, which can occur anywhere...
