Inner support type cholangiography tube through cystic duct in laparoscopic surgery

Abstract

The invention relates to the technical field of radiography tubes, and particularly discloses an inner support type cholangiography tube through a cystic duct in a laparoscopic surgery. The inner support type cholangiography tube comprises a cholangiography tube body; a sealing cover is movably inserted into the top of the cholangiography tube body; a rubber outer tube is fixedly connected to thetop of the sealing cover; a protective cover is arranged at the bottom of the cholangiography tube body; a fixed block is fixedly connected to the position, close to the bottom, of an inner cavity ofthe protective cover; a liquid outlet is formed in the center of the top of the fixed block; and the liquid outlet penetrates through the fixed block and the protective cover. According to the inner support type cholangiography tube through the cystic duct in the laparoscopic surgery, through the arrangement of a supporting outer ring, a supporting inner ring, an inner tube, a supporting rod and other structures, when the cholangiography tube body is inserted, the supporting outer ring, the supporting rod and the supporting inner ring can be effectively utilized for supporting, so that the problem that conveying of a contrast agent is influenced as the cholangiography tube is prone to being extruded during intubation is solved.

Description

technical field [0001] The invention relates to the technical field of contrast tubes, in particular to an internal stent-type cholangiography tube passing through the cystic duct in laparoscopic surgery. Background technique [0002] Contrast catheter is the key equipment for percutaneous angiography. It should have appropriate hardness, elasticity, flexibility and torsion; it should have good X-ray transparency; it should have good shape memory; should be kept to a minimum. Contrast catheter is a long plastic tube, its main function is to provide a guide for the contrast agent to be smoothly introduced into the blood vessel to produce contrast effect; while cholecystography uses iodine-containing contrast agent injected into the body to visualize the gallbladder, which can be more accurate line of diagnosis and treatment. [0003] When the existing contrast tube is intubated, due to the high pressure in the biliary tract, the contrast tube is easily squeezed and deformed...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a stent-type cholangiography tube through the cystic duct in laparoscopic surgery, which can support the inside of the cholangiography tube without affecting the contrast agent input, and is sealed at the joint with the delivery device The advantage of compactness solves the problem that there is no support inside the traditional contrast tube, which is easily deformed by extrusion, which has a certain impact on the input of contrast agent, and when the contrast agent is injected at its socket, the contrast agent may overflow The problem
