An integrated puncture perfusion catheter for perfusion of abdominal organ transplantation donors

Abstract

The invention discloses an integrated puncture perfusion catheter for perfusion of abdominal organ transplant donors. One end of the integrated puncture perfusion catheter is provided with a puncture part, and the puncture part includes a puncture part, an accommodating channel and a controllable The puncturing member is retracted into the retreating assembly in the accommodating channel, the puncturing member is arranged in the accommodating channel and can stretch in and out of the accommodating channel, and the retracting assembly is connected with the puncturing member. The invention has the advantages of convenient operation, good puncture effect, avoiding blood spatter, preventing damage to the intima of blood vessels, effectively improving perfusion efficiency, ensuring the quality of donor organs, and the like.

Description

technical field [0001] The invention relates to the technical field of organ transplantation donor surgical instruments, in particular to an integrated puncture perfusion catheter used for perfusion of abdominal organ transplantation donors. Background technique [0002] In the operation of donors donated by abdominal organs (such as liver, kidney, pancreas, small intestine, etc.), it is necessary to establish a perfusion system for abdominal organs 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, it is also necessary to avoid the flow of perfusate into unnecessary organs. The current surgical method is as follows: first, the abdominal aorta below the superior mesenteric artery is exposed, the distal aorta is ligated, the proximal end is ligated, the proximal aortic wall is incised, and an adult urinary catheter ...

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
