Abstract
A suture-free clasp for vascular anastomosis, which relates to the technical field of vascular anastomosis. The clasp comprises a first end part (), a second end part (), a rotating shaft (), a binding belt () and a rotation-stopping structure (). The rotating shaft () is rotationally installed on the first end part (); and one end of the binding belt () is fixed to the rotating shaft (), and the other end of the binding belt () is fixed to the second end part (). The second end part () is configured to be able to buckle with the first end part (); and the rotation-stopping structure () is arranged between the first end part () and the rotating shaft (), and the rotation-stopping structure () is configured to be able to lock the rotating shaft () on the first end part (). The suture-free clasp for vascular anastomosis reduces the influences of human factors of doctor during vascular anastomosis on the knotting position and knotting strength, thereby solving the technical problems in the prior art in which knotting operations are difficult, pseudoaneurysms occur since slipping happens easily during knotting which then causes blood leakage, and readjustments are difficult after knotting is complete.
