Magnetic vascular anastomosis device for rapid liver transplantation

A magnetic vascular anastomosis device for rapid liver transplantation, comprising:

• a O-shaped magnetic ring (1), which has a cylindrical shape or an oval shape;
• a C-shaped magnetic ring (2) having a longitudinal through notch (20) extended from an inner circumferential wall of the C-shaped magnetic ring (2) to an outer circumferential wall thereof, wherein a cross sectional shape of the O-shaped magnetic ring (1) is the same as a cross sectional shape of the C-shaped magnetic ring (2);
• a O-shaped base member comprising a O-shaped base body (100) having a central through slot (101), a O-shaped protrusion (5) extended from the base body at a position around the central through slot (101), and a structure for proline threading provided at the O-shaped base body (100) outside the O-shaped protrusion (5);
• and
• a C-shaped base member comprising a C-shaped base body (200) having a central through slot (201), a C-shaped protrusion (15) extended from the base body at a position around the central through slot (201), and a structure for proline threading provided at the C-shaped base body (200) outside the C-shaped protrusion (15), wherein the C-shaped protrusion (15) and the C-shaped base body (200) form a through gap (202), wherein the C-shaped base member further comprises a positioning member (16) integrally, outwardly and radially extended from the C-shaped protrusion (15), wherein a width of the positioning member (16) is equal or slightly smaller than a width of the longitudinal through notch (20) of the C-shaped magnetic ring (2).
