Abstract

The invention discloses a vascular stent firm in supporting. The vascular stent is tubular and comprises a plurality of oval metal netted ring units which are distributed axially and connected through connectors. Each netted ring unit includes a plurality of netted rings connected closely. The vascular stent is wound with metal fixing rings outside, and the metal fixing rings are respectively arranged in the middle of each netted ring unit. The metal fixing rings which are wound outside the vascular stent and respectively arranged in the middle of each netted ring unit prevent the vascular stent from slipping off blood vessels and from deformation so as to improve firmness and support performance of the vascular stent greatly.
