Abstract

The invention relates to an oversleeve type aorta anastomosis device, which is characterized by comprising an anastomosis device oversleeve, wherein the oversleeve is cylindrical or round platform shaped; the diameter of the front end of the oversleeve is smaller or is equal to the diameter of the rear part, but the front end is encircled by preset ligature; the middle part of the oversleeve is encircled by a preset ligature; and the rear part of the oversleeve is encircled by a preset ligature and can be open or unopened. The oversleeve type aorta anastomosis device comprises the other strip-shaped anastomosis oversleeve which is frapped and fixed by Velcro; a supporting bracket is cylindrical or round platform shaped; the outer surface and / or the inner surface of the supporting bracket can be provided with a soft incrusting matter; the supporting bracket can be connected with an artificial blood vessel; and the artificial blood vessel can be of a straight tube type, a bent tube type or a branching type, and each type of the artificial blood vessel can be provided with a branch blood vessel. The oversleeve type aorta anastomosis device is additionally provided with a breaking saccule. The oversleeve type aorta anastomosis device is used for the vascular anastomosis of an aorta operation.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a sleeve-type large blood vessel anastomosis device and a method of use thereof. The invention belongs to the field of cardiovascular surgical instruments. Background technique [0002] In the prior art, the effective treatment method for thoracoabdominal aortic aneurysm and extremity large vessel aneurysm is mainly surgical operation. However, the current problem is that the operation is risky and requires high technical requirements for surgeons. From the perspective of surgery, how to perform vascular anastomosis safely and quickly is an important factor to improve the success rate of surgery, reduce surgical mortality and reduce surgical complications. Especially in the surgical treatment of severe macrovascular diseases (such as complex and extensive dissecting aneurysms), whether the vascular anastomosis can be completed quickly and safely is a prerequisite for successful surgery....
