Background

Tumors of the biliary system include gallbladder and bile duct (from left and right hepatic ducts to extrahepatic bile duct of the lower segment of common bile duct), and are classified into benign and malignant tumors, and most of the malignant tumors are cancer. The primary bile duct cancer is rare and accounts for 0.01-0.46 percent of the common autopsy, 2 percent of the autopsy of tumor patients and 0.3-1.8 percent of biliary tract operation. Because most bile duct system tumors are hidden in early symptoms and lack of specificity in clinical manifestation, early diagnosis is difficult and missed diagnosis is easy, and most of the tumors belong to the late stage when diagnosis is confirmed. Therefore, the onset age is usually 50 to 70 years.

The electric coagulation hook is adopted for cutting bile duct tumor clinically, the electrified electric hook is used for cutting the bile duct tumor, forceps and other forceps are needed to be matched, the tumor is stabilized through supporting, and then cutting is carried out, so that the cutting speed is high. However, in a specific clinical operation, the wound area cut by the electrocoagulation hook is large, and because the wall of the bile duct is thin, the organ can be damaged when the electrocoagulation hook is cut.

Therefore, the method becomes a problem to be solved in the present stage!
