Donor Liver Rapid Fixed Perfusion Device in Liver Transplantation

Abstract

The invention relates to the medicine field, especially relates to a perfusion device, which can rapidly carry out connection and perfusion when obtaining a supplied liver in an organism (liver) transplant operation, and specifically relates to a supplied-liver quickly-fixed perfusion device for liver transplant. The perfusion device comprises a puncture guiding device and a connecting ring for connecting a perfusion pipe. The puncture guiding device is a puncture steel wire, a contractible and magnetic ring is arranged on the top end of the steel wire, the top end of the connecting ring is in a conical shape, the bottom of the connecting ring is connected to a perfusion pipe, a unidirectional valve is arranged in the bottom of the connecting ring, the top of the connecting ring is made of an iron-containing material, the top of the connecting ring is matched with the contractible ring, and the top of the connecting ring and the contractible ring absorb on each other through magnetic force. The operation of the device is simple, practicable, and pertinent. The device is mainly used to carry out rapid perfusion when obtaining a supplied liver in a liver transplant operation, and is capable of rapidly and effectively performing liver perfusion so as to obtain a high quality liver.

Description

technical field [0001] The invention relates to the field of medicine, in particular to the accurate and rapid connection and perfusion of a perfusion device when obtaining a donor liver during organ transplantation (liver), in particular to a rapid fixed perfusion device for a liver during liver transplantation. Background technique [0002] At present, liver transplantation has become a routine treatment for end-stage liver disease. This year, with the continuous promotion and improvement of liver transplantation technology in my country, the survival rate after liver transplantation has been continuously improving. 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 perfusion of the liver in situ. How to accurately locate and quickly perform catheter fixation and perfusion is a technical problem in obtaining high-quality liver sources. [0003] When obtaining a ...

AI Technical Summary

Problems solved by technology

However, in this process, the intubation is prone to be too deep. At this time, the perfusate flows to the right hemihepatic roof, which may easily lead to insufficient perfusion of the left and right livers. The cooling rate in the middle is slower, resulting in differences in the ischemia time between the left and right livers

In addition, in the process of intubation fixation, traditional thread ligation also affects the installation time of the overall perfusion device depending on the operator's proficiency

At the same time, there is no device to prevent liquid reflux in the traditional perfusion pipeline, and the liquid perfusion completely relies on gravity to enter the donor liver. During the entire perfusion process, various factors may cause the perfusate to reflux at any time, resulting in a slowdown of the perfusion speed.
