In this embodiment, it should be noted that during use, multiple people can cooperate with the vascular clamp, or it can be used by a single person multiple times. Specifically, the medical staff holds the handle 12 and, according to the position of the blood vessel to be anastomosed, Move the handle 12 to rotate the clamp rod 11 around the first rotating axis 22, open the clamp head 13, move the clamping part at the end of the clamp head 13 to the blood vessel to be anastomosed, and then press the movable splint 61 in the clamping part, The movable splint 61 is opened, and the spring member 93 is compressed at this time, and then the blood vessel is located between the movable splint 61 and the fixed splint 62. Then the movable splint 61 is released, and the compressed spring member 93 rebounds, driving the movable splint 61 to reset. And clamp the blood vessels to complete the blocking of blood flow;

After blocking the blood flow, the medical staff can move the handle 12, move the clamp rod 11 and the clamp head 13, and adjust the position of the clamp head 13 in the horizontal direction to bring the two blood vessels closer to each other. In addition, by setting two No. 5 rotating shaft, the clamp head 13 can rotate up and down around the No. 2 rotating shaft 5, and the position of the clamp head 13 can be adjusted in the vertical direction to further align the two blood vessels to facilitate anastomosis of the blood vessels;

By arranging the tooth block 10 on the movable splint 61 and the fixed splint 62, the friction between the movable splint 61 and the fixed splint 62 can be increased to avoid the blood vessel from falling off when clamping the blood vessel. In addition, by removing the end of the tooth block 10 The arc shape can avoid scratching blood vessels during clamping and improve the safety of surgery.
