Abstract

The invention discloses a fast perfusion device for a liver donor during liver transplantation, which comprises a perfusion tube, a fixed sleeve, a fixed shaft, a toothed knob, a spacer sleeve, an adjustment block, a penetrating wire, a one-way valve I, an injection ball, II One-way valve, connecting hose, interface end, telescopic connecting tube, shunt tube, and separation plate, first of all, through the innovative design of built-in plug-in shunt balance chamber, it can avoid the insufficient perfusion of left and right livers, and cooperate with the telescopic cone The tip of the shunt is sharp, which can not only quickly pierce the blood vessel wall and open up the blood vessel, but also can retract to avoid the continuous existence of the sharp tapered end, which improves the safety of the operation. In addition, the front end of the shunt tube is designed in a hole shape, which is convenient for perfusion The liquid flows into the liver quickly, and combined with the one-way liquid injection mechanism, it avoids the reflux situation and ensures the liquid injection effect.

Description

technical field

[0001] The invention relates to the technical field of liver transplantation perfusion, in particular to a rapid perfusion device for donor livers in liver transplantation. Background technique

[0002] At present, liver transplantation has become a routine treatment for end-stage liver disease. With the continuous promotion and improvement of liver transplantation technology in my country this year, the survival rate after liver transplantation has been continuously improved. The incidence of postoperative complications is also decreasing year by year. In liver transplantation, one of the key techniques in obtaining the donor liver is in situ perfusion of the liver. How to accurately locate and quickly perform catheter fixation and perfusion is a technical difficulty in obtaining high-quality liver sources.

[0003] When traditional donor livers are obtained, the liver is quickly explored after laparotomy to find out whether there is cirrhosis, liver mass,...
