Embodiment Construction

[0017] Please refer to figure 1 and figure 2 , a composite human great vessel intraoperative stent system, comprising an anastomotic artificial blood vessel 1 , a wire-controlled release left subclavian artery stent graft 2 , and a balloon-expandable descending aorta graft with a balloon 31 inside. Membrane stent artificial blood vessel 3; the artificial blood vessel 1 is connected to the artificial blood vessel 3 of the ball-expandable descending aortic stent-graft, and the left subclavian artery stent-graft vessel 2 is located between the artificial blood vessel and the ball-expandable descending aorta. The junction of the membrane stent artificial blood vessel 3, and the left subclavian artery stent graft vessel 2 communicates with the artificial blood vessel 1 and the ball-expandable descending aorta stent-graft artificial vessel 3; the ball-expandable descending aorta stent graft The distal end of the stent artificial blood vessel 3 extends outwards to form an extension...

Abstract

The invention provides a compound type human great artery intraoperative stent system. The compound type human great artery intraoperative stent system comprises an anastomosable artificial blood vessel, a release-by-wire left subclavian artery covered stent blood vessel, and a balloon-expanding type descending aorta covered stent artificial blood vessel provided with a balloon inside. The distalend of the balloon-expanding type descending aorta covered stent artificial blood vessel extends outwards to form an extending portion covering the spinal cord area. The extending portion and the balloon-expanding type descending aorta covered stent artificial blood vessel are integrally formed. A plurality of rows of through holes are evenly distributed in the tube wall of the extending portion,and the diameters of the through holes are 2-3 mm. By adding the extending portion and arranging the through holes, namely openings, it is possible to extend the balloon-expanding type descending aorta covered stent artificial blood vessel while avoiding completely covering the opening of the spinal artery, thereby reducing the possibility of paraplegia due to spinal cord ischemia.

Description

【Technical field】 [0001] The invention relates to the field of medical technology, in particular to a composite stent system for intraoperative human large blood vessels. 【Background technique】 [0002] Type I aortic dissection or ascending aorta and aortic arch aneurysm is still one of the most complicated and risky diseases in the field of cardiovascular surgery. The mortality rate of type I aortic dissection is extremely high. From the onset to the first 48 hours, the mortality rate increases by 1% for every additional hour. Without surgical treatment, the mortality rate within 3 months is as high as 99%. The mortality rate of ascending aorta and aortic arch aneurysm rupture is close to 100%. The current standard method for dealing with such diseases is Sun's surgery (ie aortic root + arch artificial vessel replacement + descending aortic elephant trunk implantation). [0003] At present, when patients with type I aortic dissection undergo Sun's surgery, deep hypothermi...
