Integrated puncture and perfusion catheter for abdominal organ transplantation donor perfusion

Abstract

The invention discloses an integrated puncture and perfusion catheter for abdominal organ transplantation donor perfusion, one end of the integrated puncture and perfusion catheter is provided with a puncture part, and the puncture part comprises a puncture piece, an accommodating channel and a retraction assembly capable of controlling the puncture piece to retract into the accommodating channel; the puncture part is arranged in the containing channel and can stretch out and draw back to enter the containing channel, and the retraction assembly is connected with the puncture part. The catheter has the advantages of being convenient to operate, good in puncture effect, capable of avoiding blood splashing, capable of preventing damage to endangium, capable of effectively improving the perfusion efficiency, capable of guaranteeing the quality of donor organs and the like.

Description

technical field [0001] The invention relates to the technical field of surgical instruments for organ transplant donors, in particular to an integrated puncture perfusion catheter for abdominal organ transplant donor perfusion. Background technique [0002] During donor surgery for abdominal organ donation (such as liver, kidney, pancreas, small intestine, etc.), it is necessary to establish an abdominal viscera perfusion system as soon as possible, and quickly reduce the core temperature of the target organ through efficient perfusion to reduce the warm ischemia time of the target organ. To improve the success rate of transplant surgery, at the same time, it is also necessary to avoid the flow of perfusate into unnecessary organs. The current surgical method is as follows: first expose the abdominal aorta below the superior mesenteric artery, ligate the distal aorta, tie the proximal end with a thread, incise the proximal aortic wall and insert an adult urinary catheter (pr...

AI Technical Summary

Problems solved by technology

[0003] During the operation, the abdominal aorta needs to be cut first during the insertion of the urinary catheter. During the operation, the blood pressure of the abdominal aorta is often too high, and some donors have aortic sclerosis, which leads to blood splashing after the incision, and the blood is very easy to spray. Therefore, the close cooperation of two surgeons is required during the catheterization process, and the operation is cumbersome. There is a possibility of repeated catheterization or even catheterization failure. Massive bleeding will affect the next operation and seriously affect the Perfusion efficiency of donor organ perfusate and organ quality
