Problems solved by technology

However, during the operation, after the "elephant trunk" stent-graft is inserted into the true cavity of the descending thoracic aorta, it is fixed with the trunk of the artificial blood vessel with sutures, and the blood vessel is clamped between the inner wall of the artificial blood vessel and the stent-graft. Even in the process of suturing the stent-graft and the artificial blood vessel, complications such as bleeding complication

Embodiment Construction

[0026] Reference Figure 1 to Figure 8 ,among them, figure 1 , figure 2 It is a schematic structural diagram of a specific embodiment of the present invention. As shown in the figure, a connection mechanism between an artificial blood vessel used in aortic surgery and a covered stent includes an artificial blood vessel 1 and a covered stent 2, and the artificial blood vessel 1 and The covered stents 2 are connected by an inner ring 3 made of hard material to form an integrated structure, wherein the inner ring 3 and the artificial blood vessel 1 and the covered stent 2 can be connected by gluing, inlaying, welding, etc. The inner ring 3 can be made of hard medical materials such as medical metal materials, medical plastic materials, etc. The inner ring 3 is sheathed with a fixing ring 4, and the fixing ring 4 is made of two hard materials such as medical metal. The two half rings are hinged to each other at one end, and the other ends of the two half rings are connected by a c...

Abstract

The invention discloses an artificial blood vessel and covered stent connection mechanism for an aortic operation. The connection mechanism comprises an artificial blood vessel and a covered stent, the artificial blood vessel and the covered stent are connected into an integrated structure through an inner ring made of a hard material, the outer side of the inner ring is sleeved with a fixing ring, and the difference of the radius of the inner circle of the fixing ring and the radius of the outer circle of the inner ring is equal to or smaller than the wall thickness of the blood vessel so that the blood vessel can be clamped between the inner circle of the fixing ring and the outer circle of the inner ring, and the step of sewing or binding is omitted. Besides, connection is more stable, more reliable and quicker, bleeding complications are not likely to happen, and the risk of operations is effectively reduced.

Description

Technical field [0001] The invention belongs to the technical field of medical devices, in particular to a connection mechanism between an artificial blood vessel and a covered stent used for aortic surgery. Background technique [0002] Aortic diseases, especially Stanford type A (DeBakey type I) aortic dissection and thoracic aortic aneurysms with a wide range of lesions are a group of cardio-macrovascular emergencies that seriously threaten the lives of patients and have a high fatality rate. Acute aortic dissection has a sudden onset and serious illness, which can cause serious complications such as vascular rupture, limb ischemia, visceral ischemia or paraplegia. The 24-hour survival rate after dissection is only 40%, and the 3-month survival rate is only 10%. In recent years, with the increase in the incidence of hypertension and arteriosclerosis, the incidence of aortic dissection has increased significantly, and the incidence is as high as 5-10 / 100,000 per year. [0003] S...
