Abstract

A magnetic vascular anastomosis device for rapid liver transplantation includes a magnetic ring assembly and a base member assembly. The magnetic ring assembly includes an O-shaped magnetic ring and a C-shaped magnetic ring coupled at a donor liver blood vessel and a receptor liver blood vessel respectively. The base member assembly includes an O-shaped base member and a C-shaped base member. The base member is categorized into a slotted base member, a columned base member, and a hooked base member for different surgical suture methods. The magnetic vascular anastomosis device incorporates with the magnetic attraction between magnetic rings, such that the entire liver transplantation vascular anastomosis process is fast, safe, and reliable. The vascular anastomosis device is able apply for different operations involving vascular anastomosis such as kidney transplantation, lung transplantation, heart transplantation, and maxillofacial surgery.
