Problems solved by technology

[0003] A Chinese patent discloses a choledochoscope guide in laparoscopic surgery (authorized notification number CN 106264426 B). This patented technology can easily guide the choledochoscope to enter the bile duct through the abdominal wall, and the guide can ensure the process of microscopic treatment. The middle choledochoscope has always maintained good maneuverability, but during the use of the guide, although the cylindrical balloon can fix the guide on the inner wall of the common bile duct, i

Abstract

The invention discloses a choledochoscope guider in laparoscopic surgery, and relates to the field of medical instruments. The choledochoscope guider comprises a first guide tube, wherein one end of the first guide tube is connected with a second guide tube, exterior of the first guide tube is movably sleeved with a laparoscope trocar, interior of the first guide tube and interior of the second guide tube are both communicated with choledochoscopes, a first threaded head is integrally formed in a middle section of exterior of the laparoscope trocar, the first threaded head is sleeved with a limiting cylinder, and the limiting cylinder is fixedly sleeved with a limiting plate. According to the choledochoscope guider, by means of an adjusting assembly, a user can conveniently adjust an expansion degree of an cylindrical airbag according to actual needs, so that the second guide tube is always located on an inner wall of the common bile duct, and the intrahepatic bile duct and the extrahepatic bile duct are fully expanded, in addition, the adjusting assembly is high in adjusting precision, and will not cause the cylindrical airbag to expand beyond the standard, thereby ensuring a clear vision.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a choledochoscope guide in laparoscopic surgery. Background technique [0002] Choledochoscopic examination is an effective method for the examination of biliary system diseases. The instruments are divided into rigid scope and flexible scope. The rigid scope can only observe the common bile duct, while the flexible scope can send the endoscope to the 2nd to 3rd grade hepatic ducts. At present, flexible choledochoscope is mostly used. Usually, there are two ways to enter the biliary system with a choledochoscope: open operation or laparoscopic operation after cutting the common bile duct and inserting it, and entering the bile duct through the T-shaped sinus after biliary surgery. During biliary tract surgery, it is necessary to know more about the condition of the biliary system, such as: whether there are intrahepatic bile duct stones, strictures, and tumors; [0003] A Chinese...
