Segmented in-aorta branch type covered membrane integrated stent with aortic valve

The invention aims to provide a segmental aorta internal branch type covered stent with aortic valve, which comprises a segmental covered main stent, an artificial heart valve and two internal branch stents, a tubular covered film is arranged outside the segmental covered main stent, the segmental covered main stent is divided into three sections, and the two internal branch stents are arranged on the outer side of the segmental covered main stent. The invention has the beneficial effects that the problem that the aorta covered stent cannot be implanted into the aorta root and coronary artery blood supply cannot be maintained at present can be solved, and favorable conditions are created for subsequent coronary artery branch stent positioning release and butt joint of a far-end aorta covered stent and the coronary artery branch stent; the problem of an anchoring area of ascending aorta lesion intracavitary treatment without the anchoring area can be effectively solved, meanwhile, the blood supply problem of c
