Suture-free clasp for vascular anastomosis

Abstract

The invention provides a suture-free clasp for vascular anastomosis, and relates to the technical field of vascular anastomosis. The suture-free clasp comprises a first end part, a second end part, arotating shaft, a binding belt and a rotation stopping structure. The rotating shaft is rotationally installed on the first end part, one end of the binding belt is fixed to the rotating shaft, the other end of the binding belt is fixed to the second end part, the second end part and the first end part can be buckled, the rotation stopping structure is arranged between the first end part and the rotating shaft, and the rotation stopping structure and the rotating shaft can be locked on the first end part. The influences of doctor human factors on the knotting position and knotting strength invascular anastomosis are reduced, and the technical problems are solved that knotting operation is difficult, pseudoaneurysm is formed since slipping easily happens during knotting and blood leakage is caused, and readjustment is difficult after knotting is completed in the prior art.

Description

technical field [0001] The invention relates to the technical field of blood vessel anastomosis, in particular to a suture-free clasp for blood vessel anastomosis. Background technique [0002] In the medical field, aortic diseases such as aortic aneurysms, especially aortic dissection, have an acute onset, rapid course of disease, complex conditions, and extremely high mortality. For the vast majority of patients with aortic aneurysm, including aortic dissection, surgery is required, in which a large artificial vessel is used to replace the diseased artery. Due to the severe edema and high fragility of most of the diseased aortic tissue, the operation of anastomosis of the artificial large blood vessel with the patient's diseased aorta is extremely complicated. Prolonged hypothermic circulatory arrest (DHCA) is prone to serious complications such as ischemic brain injury or spinal cord injury. In order to reduce the time of aortic anastomosis, reduce the chance of anastom...
