Background

With the improvement of living standard, the adjustment of dietary structure, the gradual popularization of physical examination and the like, the prevalence rate of gall bladder stones in China is gradually increased, and at present, the prevalence rate is more than 10%, so that the gall bladder stones become common diseases and frequently encountered diseases in China. Because cholecystolithiasis can cause symptoms of digestive tracts such as abdominal distension and dyspepsia, severe patients induce biliary colic, complicated bile duct infection, obstructive jaundice, pancreatitis and the like, and are closely related to bile duct tumors, sufficient attention needs to be paid to treatment of cholecystolithiasis, and early discovery and treatment are achieved.

The existing duodenoscope cannot enter a bile duct or the inner end of a pancreatic duct, and the internal conditions of the bile duct and the pancreatic duct cannot be observed through the duodenoscope.

In the prior art, a large hospital usually has perfect medical equipment and medical environment, and medical staff does not need to worry about the pollution problem caused by taking out a duodenoscope and a lithotomy device from a bile duct of a patient for many times in the operation process, but clinically, the duodenoscope and the lithotomy device are difficult to control due to the separated arrangement, and sometimes even need to be taken blindly. And on the other hand, the visual angle of the lens is difficult to place at the center of the bile duct for observation, which causes inconvenience in the operation process. Meanwhile, in the existing medical treatment, a surgeon needs to perform an operation in a well-equipped operating room, and in some medical assistance activities, such as rescue and non-equal activities, the supported area is economically lagged, conditions in all aspects are limited, perfect medical environment and medical equipment cannot be provided, and sometimes even an operation needs to be performed under extremely crude conditions, so that the problem of pollution caused by taking the duodenoscope and the lithotomy instrument out of the bile duct of the patient for many times is possibly fatal. On the other hand, the duodenoscope equipment in the prior art is too bulky, inconvenient to move and incapable of being carried about, and the treatment efficiency of medical staff is greatly reduced due to the lack of the help of necessary medical instruments in the medical assistance action.
