Peroral cholangioscopy guide device and application method thereof

Abstract

The invention provides a peroral cholangioscopy guide device and an application method of the peroral cholangioscopy guide device, and relates to the technical field of medical apparatus and instruments. The peroral cholangioscopy guide device and the application method aim at solving the technical problem that the operation difficulty of a direct cholangioscopy is large by conducting choledochoscope inlet by hand. The peroral cholangioscopy guide device comprises a catheter, an inflatable balloon and a guide zebra guide wire for guidance of ultra-fine gastroscope inlet. The far end of the catheter penetrates out of the balloon and is fixedly connected with the balloon, an air injection channel for inflation of the balloon and a second channel which is used for allowing a traction object, entering a bile duct, of a traction guide device to penetrate through and runs through the far end and the near end of the catheter are arranged in the catheter, the guide zebra guide wire is arranged outside the catheter, the far end of the guide zebra guide wire is fixedly connected with the outer wall of the catheter, and the near end of the guide zebra guide wire is a free end. According to the device, an ultra-fine gastroscope can be conveniently guided to enter the bile duct in a peroral mode, the gastroscope inlet difficulty is low, average gastroscope inserting time is 11.5 min, the gastroscope inserting success rate reaches 92.9%, and it can be guaranteed that the ultra-fine gastroscope is always easy to control in the process of gastroscope treatment operating process.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to the technical field of medical devices in the diagnosis and treatment of biliary tract diseases. Background technique [0002] Cholangioscopy and cholangioscopy technology are widely used clinically, and have become one of the most important diagnostic and therapeutic methods for extrahepatic and extrahepatic biliary tract diseases and special cases, and have become one of the most important minimally invasive techniques for biliary tract surgery and liver surgery one. Generally, choledochoscopy can be divided into two types according to the route of entry: through the artificial channel and through the natural orifice. The former category includes T-tube sinus tract, percutaneous transhepatic and intraoperative choledochoscopy, etc. Oral choledochoscopy technique. [0003] Oral choledochoscopy is a new type of choledochoscopy developed in recent years. Like a duodenos...
