Vascular anastomosis device with two clamping fastening ends

The invention discloses a vascular anastomosis device with two clamping fastening ends. The device comprises an anastomosis ring I, an anastomosis ring II and traction belts, wherein the anastomosis ring I takes the shape of a cylinder; a plurality of convex bodies I are arranged on the outer side surface of one end of the anastomosis ring I; a circle of convex-concave alternative bodies I which face outwards are arranged on the outer edge of the other end of the anastomosis ring I; the anastomosis ring II takes a shape and a size identical to those of the anastomosis ring I; a plurality of convex bodies II are arranged on the outer side surface of one end of the anastomosis ring II; a circle of convex-concave alternative bodies II which face outwards are arranged on the outer edge of theother end of the anastomosis ring II; one end, with the convex bodies II, of the anastomosis ring II, is in butt joint with one end, with the convex bodies I, of the anastomosis ring I; a plurality ofthe traction belts are of
