Novel anastomosis system of blood vessels and blood vessel stent

Abstract

The invention discloses a novel anastomosis system of blood vessels and a blood vessel stent. The system comprises a branched artificial blood vessel group, a stent artificial blood vessel group, a suture-free ring and an anastomosis buckle device; a main body of the branched artificial blood vessel group is a main body artificial blood vessel of a tubular structure, a main branched artificial blood vessel of a tubular structure is fixedly communicated with the upper end of the main body artificial blood vessel, and three branched blood vessels are fixedly communicated with the upper end of the main branched artificial blood vessel. By means of the system, the surgical step is simplified, the surgical difficulty is lowered, then the in-vitro time, the surgical time, the deep hypothermia circulatory arrest time and the brain protection time are greatly shortened, the surgical mortality rate is reduced, and the morbility of nervous systems and other complications is lowered at the same time. Few anastomotic stomas are involved, through buckling of the anastomosis buckle device and the suture-free ring, the bleeding probability is lowered, the mortality rate is lowered accordingly, and the success probability of operations is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of artificial blood vessel implantation, in particular to a novel anastomosis system for blood vessels and vascular stents. Background technique [0002] Acute aortic dissection is the most common and dangerous disease in acute aortic syndrome. Although its clinical prognosis has been greatly improved and improved due to early diagnosis and timely surgical treatment, its early mortality and Long-term reoperation rates remain high. There are two commonly used classification methods for traditional aortic dissection: Stanford classification and Debakey classification. For the Stanford classification, no matter which part the dissection originates from, as long as the ascending aorta is involved, it is called type A; if the dissection originates from the descending thoracic aorta without involving the ascending aorta, it is called type B. Debakey divides aortic dissection into three types: type I, aortic diss...

AI Technical Summary

Problems solved by technology

[0006] 1. The operation method is complicated, the external time, operation time, deep hypothermia circulatory arrest time and brain protection time are prolonged, and the surgical mortality rate, nervous system and other complications are significantly increased;

[0007] 2. There are many anastomotic stomas so that bleeding is relatively easy, intraoperative hemostasis is difficult, and intraoperative and postoperative bleeding is large, thereby increasing mortality
