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.

Abstract: Disclosed is a magnetic compression anastomosis system for laparoscopic cholangioenterostomy, including an emission gun, daughter and parent magnetic rings, and an assisting rod, wherein the parent magnetic ring is positioned at the stump of a common bile duct in a purse string suture manner, the relative position is fixed by the assisting rod, the emission gun is loaded with the daughter magnetic ring and makes the same in butt joint with the parent magnetic ring by an intestinal cavity channel of an intestinal tube, the distance between the daughter magnetic ring and the parent magnetic ring is continuously shortened by a push rotary button of the emission gun, and when the relative distance between the daughter and the parent magnetic rings is shortest and mutual attraction is realized, separating the daughter magnetic ring from the emission gun is achieved by an activation mechanism of the emission gun, realizing laparoscopic cholangioenterostomy.
