Medical equipment for assisting in biliary calculus and pus clearing in surgeries

Abstract

The invention relates to the field of medical treatment, in particular to medical equipment for assisting in biliary calculus and pus clearing in surgeries. The medical equipment comprises a pipelinewith one side open, the head portion of the other side of the pipeline is closed, and the side wall, close to the closed head portion of the pipeline, is provided with more than one inclined hole. Theopen side of the pipeline can be connected with an external container. The head portion is closed and semispherical and is smoother in surface after being moistened by body fluid, and friction with tissues is reduced; in biliary tract flushing, a water column is prone to changing flow direction when meeting a biliary duct wall parallel to the biliary tract, evident reduction of water column impact force is avoided, the water column is capable of beneficially entering a calculus far side from a gap between calculi and the biliary duct wall, and accordingly the internal pressure of the biliarytract at the calculus far end is evidently increased in short time to form vortex so as to push the calculi to move towards the first porta hepatis, and clearing of silt-like calculi and pus in the biliary tract can be realized.

Description

technical field [0001] The invention relates to the medical field, in particular to a medical instrument for helping to clean up biliary stones and pus during operation. Background technique [0002] With the development of biliary stone surgery technology, especially intrahepatic stone removal, many domestic scholars have successively modified and invented a variety of stone removal devices to optimize and improve the efficiency of biliary stones, but none of them are perfect, especially the devices for biliary irrigation. Most scholars use a disposable drainage tube or catheter for biliary irrigation. The water column sprayed from the irrigation tube is perpendicular to the side wall of the biliary tract, and it is difficult for the water flow to impact the distal stones, so the biliary irrigation effect is poor. Contents of the invention [0003] Purpose of the invention: In order to provide a medical device with better effect to help clear up biliary calculus and pus d...

Problems solved by technology

[0002] With the development of biliary stone surgery technology, especially intrahepatic stone removal, many domestic scholars have successively modified and invented a variety of stone removal devices to optimize and improve the efficiency of biliary stones, but none of them are perfect, especially the devices for biliary irrigation. Most scholars use a disposable drainage tube or catheter for biliary irrigation. The water column sprayed from the measurement and control of the irrigation tube is perpendicular to the side wall of the biliary tract, and it is difficult for the water flow to impact the stones at the far end, so the biliary irrigation effect is poor.
