Anastomotic buckle for aorta and artificial blood vessel assembly using same

Abstract

The invention discloses an anastomotic buckle for aorta and an artificial blood vessel assembly using the same, relates to the technical field of medical devices, and solves the existing technology of inconvenient operation and difficult adjustment when knotting and fixing the collar of an artificial blood vessel with silk threads (or ribbons) question. The anastomotic buckle for aorta according to the present invention comprises: a buckle body, the buckle body is an annular opening structure, and the first instrument operation holes are respectively arranged on the two sides of the opening on the buckle body; one end of the buckle body There is a first fastening part, and a second fastening part is provided at the other end. The first fastening part and the second fastening part are inserted and locked together, so that the anastomotic buckle for the aorta can be set and fixed on the artificial The outer side of the loop of the blood vessel; the more the overlapping parts of the first fastening part and the second fastening part are inserted and locked, the smaller the diameter of the anastomotic buckle for the aorta; the first fastening part and the second fastening part The less overlapping parts are interfitted and locked, the larger the diameter of the anastomotic buckle for the aorta is.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anastomotic buckle for aorta and an artificial blood vessel assembly using the same. Background technique [0002] Aortic disease has plagued cardiovascular surgeons since the birth of cardiovascular surgery in the 1950s. Aortic diseases, such as aortic aneurysm, especially aortic dissection, have an acute onset, rapid course of disease, complex conditions, and extremely high mortality. The vast majority of aortic aneurysms, including aortic dissection, require surgery to replace the diseased artery with a large artificial vessel. 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 and technically difficult. Prolonged circulation (DHCA) time is prone to severe complications such as ischemic brain injury or spinal c...
