Technical Field

The invention relates to the field of stone removal equipment for hepatobiliary surgery, in particular to an auxiliary device for hepatobiliary surgery stone removal.

Background

Calculus of intrahepatic bile duct is a common and intractable biliary tract disease in our country. The complicated pathological changes often cause serious complications and become an important cause of death of biliary tract disease patients in China. Minimally invasive choledochostomy is to open the common bile duct by using a laparoscope, and take out the calculi by entering the liver by using a choledochoscope technology, and a pure choledochostomy drainage operation is mostly used for emergency and severe cases and aims at temporarily smoothing bile flow, controlling biliary tract infection and improving liver function to save the life of a patient or preparing for a second-stage definitive operation. Only in a few cases that the quantity of calculi is small, the affected hepatic duct and liver lesions are slight, no residual focus exists inside and outside the liver after the calculi are removed, and no bile duct is narrow, the single incision of the hepatic bile duct can be used as a deterministic operation mode, the hepatic portal bile duct and the hepatic bile duct are jointly incised, the hepatic bile duct is incised through the liver parenchyma, and the calculus is observed and removed by combining a choledochoscope, so that the calculi in the hepatic duct can be effectively removed;

after the total bile duct is incised to remove stones or explored, a T-shaped tube is required to be placed for drainage, and residual silt-like stones and bile containing toxin in the bile duct are discharged out of the body, so that the bile duct is supported and drained, edema and inflammation caused by surgical trauma of the bile duct are relieved, and the bile is prevented from flowing into an abdominal cavity along the incision of the bile duct to form biliary peritonitis.

The applicant finds that at least the following technical problems exist in the prior art: because the laparoscopic minimally invasive hepatobiliary calculus removal operation needs a doctor to observe a lens transmission picture for operation, when a drainage T tube is placed in an incision bile duct and a bile duct incision is sutured, the doctor needs to manually perform needle application suturing in a narrow operation area, especially, the operation difficulty is higher in the single-hole laparoscopic operation, the traditional single-needle suturing needle needs the doctor to take a needle holder to clamp a needle body for multiple angle adjustment so as to perform reciprocating suturing on two sides of the incision, the requirement on the operation experience of the doctor is higher, the suturing speed is low, the bile duct incision suturing firmness is difficult to guarantee, and a suturing device suitable for bile duct incision suturing does not exist in the market.
