Device for laparoscopic transcystic duct cholangiography

Abstract

The invention relates to a device for laparoscopic transcystic duct cholangiography, which comprises a cholangiography tube, a clamp and clamp forceps, wherein the cholangiography tube needs to be inserted into the head of a biliary tract and slightly expands outwards; the front parts of the two clamping arms of the clamp are bent outwards; a plurality of longitudinal prints and transverse prints are arranged on the inner side of the clamp; and strip-shaped grooves in the length direction of the head of the clamp are formed in corresponding surfaces of two heads of the clamp forceps to accommodate the clamp. According to the device, the cholangiography tube is effectively caused to be inserted into the biliary tract, without slipping, when being clamped by the titanium clamp forceps, the titanium clamp does not slip and the non-smoothness or blocking of a contrast agent when the cholangiography tube is clamped by the titanium clamp is prevented, and the device has a simple structure, and is more convenient and faster in cholangiography operate.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a radiography device in the endocervical canal of the gallbladder, in particular to a radiography device through the endocervical canal of the gallbladder under a laparoscope. Background technique [0002] With the improvement of quality of life, the incidence of gallstones is increasing. In the past, the best treatment for gallbladder stones was cholecystectomy through the abdominal cavity. However, when the gallbladder stones are small, the gallbladder itself can shrink the stones into the common bile duct. This situation is medically known as secondary bile duct stones. Once there are stones in the bile duct, surgery must be done to open the bile duct and remove the stone inside. Therefore, it is very important to know whether there are gallstones in the bile duct before the operation. The common method in surgery is transcystic duct cholangiography. That is, insert a small co...

Problems solved by technology

It is used to solve the problem that the titanium clip slips from the titanium clip when the titanium clamp head clamps the titanium clip in the prior art, and the contrast agent flows out after the contrast tube is inserted into the biliary tract, and the contrast medium injected into the biliary tract leaks out. , and the injection of the contrast agent in the contrast tube is not smooth or blocked
