Abstract

The invention discloses a suture-free stent artificial blood vessel, relates to the technical field of medical devices, and aims to solve the problems of difficult anastomosis of existing artificial blood vessels, blood leakage and complications caused by too long anastomosis time. The suture-free stent artificial blood vessel according to the present invention comprises: an artificial blood vessel body composed of artificial blood vessels in the textured part and artificial blood vessels in the non-textured part connected in sequence, and the artificial blood vessel in the non-textured part is sutured with a compressible elastic metal Stent; there is a suture-free connection part on the artificial blood vessel of the textured part, and the suture-free connection part consists of a soft annular pocket that is located on the outside of the artificial blood vessel of the textured part and is coaxially seamlessly connected with the artificial blood vessel of the textured part, and placed on the The superelastic braided fixing ring is formed between the soft ring pocket and the artificial blood vessel of the textured part, and the superelastic braided fixing ring is provided with a height restraint device along the elastic direction; the superelastic braided fixing ring is a grid structure staggered up and down, And it is braided by super elastic nickel-titanium alloy wire.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a suture-free stent artificial blood vessel. Background technique [0002] Aortic dissection is a dangerous, rapidly progressive, high-mortality aortic disease with an incidence rate of approximately 0.3%, an early untreated mortality rate that increases by 1% per hour, and more than 50% of patients die within 1 week . Aortic dissection has a rapid onset and a very poor prognosis, and even patients who survive will go on to develop chronic aortic dissection with multiple clinical manifestations. The location of aortic dissection rupture is the core factor in determining the surgical method. The rupture is located in the descending aorta, that is, type B dissection. Because of its small incision, high success rate, good treatment effect, and rapid postoperative recovery, endovascular repair of the aorta has replaced it. Most of the traditional open thoracotomy has gradua...
