AI Technical Summary
Technical Problem
In the prior art, the clad vascular stent is difficult to firmly support the side of the aortic vascular stent in large aortic aneurysm surgery, and requires multiple operations and is not easy to use.
Method used
A blood vessel stent for clinical cardiovascular intervention is designed. By setting rotating racks and limited components on the second frame, a single support effect in the vascular can be stabilized.
Benefits of technology
Simplify the operation steps of vascular brackets, reduce the risk of surgery, increase the contact area of the vascular stent and the internal stent of the aorta, and ensure a more stable support effect.

Abstract
The invention relates to the technical field of interventional medical instruments, in particular to an intravascular stent for clinical cardiovascular intervention.The intravascular stent comprises at least two sets of first stents and at least two sets of second stents which are coaxially arranged at intervals, and the first stents and the second stents form a cylindrical supporting structure; the two sets of second supports are oppositely arranged between the two sets of first supports, the first supports and the second supports are connected with each other through a plurality of first connecting rods, and the two sets of second supports are connected with each other through second connecting rods; operation cavities are formed in the two second supports, the rotating frame is rotationally installed on the second supports where the operation cavities are located, and a limiting assembly used for limiting rotation of the rotating frame is arranged on the second connecting rod. In the invention, in the state that the second stent is opened in the blood vessel of the patient, the limiting assembly releases the limitation on the rotating frame, and the rotating frame can support the position of the branch blood vessel.
