Problems solved by technology

[0002] At present, due to the relatively simple structure of the existing biliary endoscopes used for minimally invasive gallbladder-preserving stone removal and polyp removal, smaller lesions such as gallbladder neck and cystic duct and more complicated clinical conditions cannot be found and effectively resolved, and only For an instrument operation channel, it is necessary to add a sheath outside the endoscope to complete the operation. The sheath provides an additional instrument channel required for the operation; in addition, due to the high quality of the peripheral equipment connected to the endoscope, the operation is inconvenient, resulting in It is difficult for the doctor to fix the endoscope correctly during the operation, and it is inconvenient to enter the delicate parts of the gallbladder for operation, which affects the quality of the operation

Abstract

The invention relates to a hard composite gallbladder endoscope for use in a microtrauma protective gallbladder endoscope lithotomy and polypectomy operation, which comprises a hard mother endoscope and a hard son endoscope, wherein the son endoscope enters a gallbladder lumen through an instrument channel of the mother endoscope. One end and a front end of each of the mother endoscope and the son endoscope adopt a hard endoscope body, wherein the hard mother endoscope comprises the instrument channel, an ocular input end, an endoscope body, a cold light source input end, an endoscope front-end, a hard endoscope end, a water inlet channel, and a water outlet channel; and the hard son endoscope comprises an instrument channel, an ocular input end, a cold light source connector, and a hard endoscope end. The two endoscopes are matched to be used, and the mother endoscope is taken as a platform; when the mother endoscope treats a pathological change of a gallbladder, the son endoscope is easier to enter micro-positions such as a gallbladder neck and a cystic duct and so on, through the instrument channel of the mother endoscope to diagnose and treat and effectively treat smaller calculi and polypi.
