The vascular clamp body has an arc shape that fits the arm, and the tail of the vascular clamp is fixed, thereby reducing the chance of the operator touching the tail of the vascular clamp and reducing the chance of the tail of the vascular clamp being entangled with the suture.

[0004] However, users in this field have found that during anastomosis surgery, the vascular clamp is required to be clamped near the vascular incision, and the vascular incision is often a side incision or an upper incision. The above-mentioned wearable arm vascular clamp does not have an angle adjustment function and is difficult to clamp the blood vessels with side incisions or upper incisions well.

[0005] Therefore, in order to better meet the actual needs of vascular anastomosis surgery, a vascular clamp that is suitable for both flat incisions and side incisions or upper incisions is needed. Summary of the Invention

[0009] Furthermore, the fixed plate is provided with a limit groove and a slide groove perpendicular to the limit groove; the adjusting member includes an adjusting disk, and an adjusting rod is fixedly connected to one side of the adjusting disk; the adjusting rod includes a screw arranged at the front and a transmission key arranged in the middle; and a threaded hole matching the screw is provided on one side of the locking member.

[0010] Furthermore, the tail of the arc-shaped vascular clamp is provided with a through hole, and a key slot is provided on one side of the through hole; the size of the through hole matches the size of the adjusting rod, and the size of the key slot matches the size of the transmission key.

[0011] Furthermore, the upper ring of the adjustment disk is provided with angle engraved lines, and the side of the fixing plate close to the adjustment disk is provided with a reference line.

[0012] Furthermore, a carry groove is provided in the slide groove.

[0013] Furthermore, the length of the transmission key does not exceed the thickness of the tail of the arc-shaped vascular clamp.

[0014] Furthermore, the side ring of the adjusting disk is provided with an anti-slip pattern; the side ring of the locking piece is provided with an anti-slip pattern.
