1. A blood vessel anastomosis set for anastomosing a blood vessel cut of a blood vessel, the blood vessel anastomosis set comprising:
a blood vessel anastomosis device, comprising:
a front-end anastomosis portion; and
a rear-end anastomosis portion having a plurality of anastomosis needles, wherein the plurality of anastomosis needles penetrate the front-end anastomosis portion, such that the rear-end anastomosis portion is movably connected to the front-end anastomosis portion through the anastomosis needles; and
a blood vessel fixation device for widening the blood vessel cut to allow the blood vessel cut to be fixed to the blood vessel anastomosis device;
wherein the blood vessel fixation device comprises a blood vessel widening portion and a blood vessel fixation portion;
wherein the first blood vessel widening portion is configured to widen the blood vessel cut gradually and allows the blood vessel cut to come into contact with the blood vessel fixation portion, and thereby cause the blood vessel fixation portion fixing the blood vessel cut to the blood vessel anastomosis device;
wherein the blood vessel anastomosis device is connected through the plurality of anastomosis needles to a second blood vessel anastomosis device, wherein the second blood vessel anastomosis device is configured to fix to another blood vessel cut;
wherein the blood vessel anastomosis device has a snap-engagement portion, and the blood vessel fixation portion is disposed at the blood vessel fixation device, in which the blood vessel fixation portion is separable with the blood vessel fixation device, wherein, as soon as the blood vessel fixation portion fixes the blood vessel cut to the blood vessel anastomosis device, the blood vessel fixation portion is snap-engaged with the snap-engagement portion, and the blood vessel cut is clamped between the blood vessel fixation portion and the blood vessel anastomosis device.
