Abstract

The invention discloses an artificial blood vessel for an aortic dissection surgery. The artificial blood vessel comprises an artificial blood vessel body, a plurality of connecting pieces, and a plurality of suturing pieces; the artificial blood vessel body is a three-layer blood vessel body; the plurality of connecting pieces are arranged at joints of the artificial blood vessel body; and the suturing pieces are matched with the connecting pieces and are arranged at the joints of the artificial blood vessel body. According to the artificial blood vessel for the aortic dissection surgery, through matched use of the connecting pieces and the suture pieces, when the artificial blood vessel communicates with a human blood vessel, operation is easy, and suture is convenient; and the artificial blood vessel provided by the invention is a three-layer blood vessel, the structure of the artificial blood vessel is furthest close to that of a human artery blood vessel, and the wall of the artificial blood vessel has good elasticity and fluffiness.

Description

technical field [0001] The invention relates to the technical field of artificial blood vessels, in particular to an artificial blood vessel for aortic dissection surgery and a method for preparing the artificial blood vessel for aortic dissection surgery. Background technique [0002] Cardiovascular disease is the disease with the highest mortality rate. According to data, there are about 300 million cardiovascular patients in China alone. Vascular graft replacement is one of the effective methods for the treatment of cardiovascular diseases, and the sources of blood vessels include allogeneic blood vessels, autologous blood vessels and artificial blood vessels. Allogeneic transplantation usually causes immune rejection, and autologous transplantation is often limited by the patient's own health, so there is a huge clinical demand for artificial blood vessels. [0003] Aortic dissection aneurysm is due to local damage to the aortic intima, high-pressure blood flow rushes ...
