Abstract

The invention discloses an aortic arch branched stent-graft blood vessel combination device for open surgery, which comprises two artificial blood vessel components: ① a section of arc-shaped artificial aortic vessel (1), and the arc-shaped artificial aortic vessel (1) Including the main blood vessel (9) and three branch blood vessels (7) on the main blood vessel (9), the main blood vessel (9) has a stent (8), and the proximal part (8a) of the stent (8) is Bare stents that can be released later; ② Covered small stent vessels (2). The use of this vascular component can quickly reconstruct the aortic arch and three-branch vessels in the operation involving the aortic arch lesion that requires total arch replacement. It can preserve the normal vessel shape to the greatest extent, and is suitable for various common branch-shaped vessels with a wide range of applications. , avoid custom-made stents, can be mass-produced, effectively reduce surgical trauma, and significantly simplify surgical operations.

Description

technical field

[0001] The invention relates to the field of implantable blood vessels, and relates to a three-branch covered stent assembly in the aortic arch that can be used in open surgery. Background technique

[0002] Thoracic aortic aneurysm and aortic dissection are serious lesions that seriously threaten the lives of the general public. Without active treatment, the natural disability rate and mortality rate are high. In recent years, with the increase in the incidence of hypertension, hyperlipidemia, hyperglycemia, and trauma, the incidence of thoracic aortic aneurysm and aortic dissection has increased significantly. Currently, aortic arch replacement under direct vision is still the only option for aortic lesions involving the proximal ascending aorta and aortic arch. At present, the most mature aortic arch replacement operation requires artificial blood vessels to replace the diseased blood vessels under deep hypothermic circulatory arrest, and anastomoses the ...
