Terylene three-branch arcus aortae artificial blood vessel with self-expandable stent

Abstract

The invention discloses a terylene three-branch arcus aortae artificial blood vessel with a self-expandable stent. A hard alloy ring and a self-expandable stent of which the internal diameters are respectively equivalent to the three branches of a three-branch Dacron artificial blood vessel and the remote-end cavity of the main body of the artificial blood vessel are respectively sewn in the three branches of the three-branch Dacron artificial blood vessel and the remote-end cavity of the main body of the artificial blood vessel, and the self-expandable stent is led out after being respectively tightened by a conveying rod of which the head end is in a bullet shape. The terylene three-branch arcus aortae artificial blood vessel with the self-expandable stent, which is disclosed by the invention, has the beneficial effects that four anastomotic stoma with difficulty in operation, at parts such as a three-branch brachiocephalic trunk and descending aorta, can be omitted, and only one proximal part anastomosis becomes pure artificial blood vessel anastomosis. The terylene three-branch arcus aortae artificial blood vessel with the self-expandable stent has the beneficial effects that the operation program is simplified, the operation safety is improved, and the terylene three-branch arcus aortae artificial blood vessel can be conveniently popularized and applied in various hospitals. The terylene three-branch arcus aortae artificial blood vessel with the self-expandable stent comprises the following components disclosed in the drawing: a proximal part 1 of the main body of the artificial blood vessel, a hard alloy ring 2 in an artificial blood vessel cavity, a self-expandable stent 3 in the artificial blood vessel cavity, a bullet-shaped head end 4 of a stent conveying rod, an artificial blood vessel branch 5, a branch conveying rod outlet 6, a conveying rod 7 and a distal end 8of the main body of the artificial blood vessel.

Description

technical field [0001] The invention relates to the field of clinical surgery, and is a novel aortic arch artificial blood vessel which can obviously simplify the reconstruction operation of the whole aortic arch and improve its safety. Background technique [0002] Aortic surgery, especially aortic arch surgery, is one of the most difficult technical fortresses for cardiac surgeons to overcome. In the case of aortic lesion, the vessel wall becomes thinner and the texture is fragile; in the case of acute aortic dissection, the inner and outer layers of the blood vessel are separated, the tissue is edema, and the texture is more fragile. When the artificial blood vessel is anastomosed with the above-mentioned extremely fragile vascular stump, it is easy to cause suture cutting and tear the vessel wall tissue; after the anastomosis is completed, the high-pressure blood in the dissection false cavity flows through these suture cutting and tearing places, resulting in The anast...

Problems solved by technology

In order to solve the problem of increased mortality caused by many anastomotic stomas, difficult anastomosis, long operation time, and difficulty in hemostasis of anastomotic stoma replacement in conventional total aortic arch replacement surgery; in order to overcome the above-mentioned many defects of the existing intraoperative stent, the present invention lasted 15 years. In 2010, a three-branch polyester artificial blood vessel with a self-expanding stent was provided (the main body is an artificial blood vessel instead of a stent).
