During operation, the aortic stent in a compressed state is delivered to the position of vascular lesions through a delivery system with a smaller tube diameter. However, since two inner chimney stents on the same side wall in the aortic stent extend along the side wall of the vessel of the aortic stent facing away from the recess, the two inner chimney stents interfere with each other in the radial direction when compressed, affecting the compression of the entire vessel of the aortic stent. After the aortic stent is released, the two inner chimney stents are mutually overlapped in the radial direction, which brings difficulty to the delivery and release of the branched arterial stent vessels and possibly causes that the two branched arterial stent vessels are simultaneously delivered and released in the same inner chimney stent. In addition, most of the existing aortic stents have a linear tubular structure, and after the aortic stent is delivered into the aortic arch part for release, the resilience force generated at the two ends of the aortic stent is large, so that the vessels at the corresponding positions of the aortic stent are greatly pressed, and even the vessels are ruptured.
