Abstract

The invention relates to the technical field of medical equipment production, and discloses a hepatobiliary surgery department negative pressure suction biliary calculus removal auxiliary device which comprises a calculus removal forceps main body, the calculus removal forceps main body can be divided into a handle part, a parallel connection part and a curved bar part from the tail end to the top end according to functions, and a flow dividing part is installed in the parallel connection part; the flow dividing piece is assembled to be used for being communicated with the negative pressure machine pipe body and the physiological salt pipe body and inputting gas / liquid into the bent lever part. A sealing mechanism is arranged at the tail end of the curved bar part, a crank is movably arranged on the parallel connection part, and the crank is assembled to switch output of gas / liquid of the flow dividing part and drives the sealing mechanism to enable the tail end of the curved bar part to be opened and closed at the same time. According to the negative pressure suction biliary calculus removal auxiliary device for the hepatobiliary surgery department, the difficulty of surgical operation is reduced, continuity is enhanced, the time needed by the operation is shortened, the labor intensity of doctors is reduced to a certain degree, and the problem that the gallbladder tissue is damaged in the surgical process is solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment production, in particular to a negative pressure suction biliary stone removal auxiliary device for hepatobiliary surgery. Background technique [0002] Gallbladder stone is one of the most common diseases in biliary surgery, and its common symptoms include biliary colic, epigastric pain, gallbladder effusion and other clinical symptoms. With the aging of the population, the change of diet structure and the promotion of parenteral nutrition, the incidence of cholelithiasis is still increasing year by year. According to epidemiological investigations, the incidence of cholelithiasis is 10%-15% in western developed countries, while the incidence of gallstones in my country is 10%-15%. The incidence of calculus is 4.42%-8.20%, and it has a tendency to increase gradually in recent years. [0003] For a long time, due to the incomplete understanding of the function of the gallbladder, it is b...
