Abstract

The invention discloses a suturing-free stent artificial blood vessel, a conveying device thereof and a coincident retaining ring, relates to the technical field of medical instruments and aims to solve the problems of blood leaking and complication caused by the fact that existing artificial blood vessels are difficult in coinciding and too long in coinciding time. The suturing-free stent artificial blood vessel comprises an artificial blood vessel body composed of a line-forming portion artificial blood vessel and a non-line-forming portion artificial blood vessel which are connected sequentially, and an elastic metal stent is arranged on the non-line-forming portion artificial blood vessel; a suturing-free connecting portion is arranged on the line-forming portion artificial blood vessel and composed of a coating member and a supporting sleeve ring, the coating member is positioned on the outer side of the line-forming portion artificial blood vessel and coaxially and seamlessly connected with the same, and the supporting sleeve ring is put between the coating member and the line-forming portion artificial blood vessel.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to a suture-free stent artificial blood vessel and its delivery device and anastomotic buckle. Background technique [0002] Aortic dissection is a dangerous aortic disease with rapid progression and high mortality. The incidence rate is about 0.3%. The untreated early mortality rate increases by 1% per hour, and more than 50% of patients die within 1 week. . The onset of aortic dissection is rapid and the recovery is very poor. Even patients who can survive will continue to develop chronic aortic dissection with various clinical manifestations. The location of the aortic dissection breach is the core factor that determines the surgical method. The breach is located in the descending aorta (type B dissection). The aortic endovascular repair technique has been replaced because of the small wound, high success rate, good treatment effect, and quick postoperative recovery. Most of...
