Liver and gall drainage device

Abstract

The invention discloses a liver and gall drainage device, and belongs to the field of medical instruments. According to the technical scheme, a compression mechanism moves to suck pus and blood clotsin a human body into a feeding mechanism, the compression mechanism moves to drive a steel wire to move in the feeding mechanism; one end of the steel wire is wound around the side wall of a roller, and the steel wire moves to drive the roller to rotate, so that the steel wire is unwound from the side wall of the roller; the roller rotates to drive a semicircular supporting block and a sharp headto rotate; the supporting block and the sharp head make contact with pus and blood clots entering the feeding mechanism; the sharp head rotates to crush the pus and the blood clots; meanwhile, the semicircular supporting block drives a conical protrusion to rotate, and the protrusion rotates to make contact with pierced pus and blood clots; and the protrusion rotates to scatter pus and blood clots, the feeding mechanism is prevented from being blocked by the pus and the blood clots, smooth drainage is guaranteed, blockage of the device in the drainage process is prevented in a physical crushing mode, other liquid media are not needed in the whole process, and unnecessary operation risks are reduced.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a hepatobiliary drainage device. Background technique [0002] Drainage is the act, process and method of drawing fluid from a body cavity or wound by means of attraction or gravity. During the hepatobiliary drainage process, some larger blood clots and pus are sucked into the catheter, and the accumulation of blood clots and pus can easily block the catheter, resulting in slow drainage, which is not conducive to the treatment of patients. [0003] Patent No. CN201520640994.3 discloses a hepatobiliary drainage device, wherein when the elastic extrusion balloon is squeezed, the flushing liquid in the elastic extrusion balloon is discharged to the flushing tube through the second one-way valve, and then flushed The tube is sent to the nozzle, and finally sprayed from the nozzle, and when the elastic extrusion balloon is released, the elastic extrusion balloon recovers ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention: when the current hepatobiliary drainage device solves the problem of unsmooth drainage caused by the easy formation of viscous effusion or large blood clots at the front end of the drainage tube, the drainage efficiency of the hepatic and biliary effusion is reduced, and it may cause unsmooth drainage. To solve the problem of necessary tissue contamination, provide a hepatobiliary drainage device that does not affect the drainage effect of the effusion, and at the same time avoids the accumulation of blood clots or viscous effusions
