Embodiment Construction

[0023] The present invention will be further described in conjunction with the following examples.

[0024] Such as Figure 1 to Figure 2 As shown, a blood vessel stent monomer 2 of this embodiment includes a bottom surface 4, a b bottom surface 3, and an edge 1. The a bottom surface 4 and the b bottom surface 3 are parallel to each other, and the a bottom surface 4 is parallel to the The b bottom surface 3 is a polygon and consists of each side of the polygon, the projection of the a bottom surface 4 on the b bottom surface 3 is included in the b bottom surface 3, and the vertex on the a bottom surface 4 passes through the The edge 1 connects the similar vertices on the b bottom surface 3, and each vertex on the a bottom surface 4 and the b bottom surface 3 has and only one of the edges 1 is connected to it, and the edge 1 includes Y-shaped edge 5.

[0025] The structure of the vascular stent monomer 2 meets the mechanical conditions required to support the vascular wall, and it...

Abstract

The invention discloses a vascular stent monomer and a vascular stent, and relates to the technical field of medical instruments. The vascular stent monomer comprises a bottom face a, a bottom face band edges. The bottom face a and the bottom face b are parallel to each other, are polygonal, and are composed of all sides of a polygon, the projection of the bottom face a and the projection of thebottom face b are included in the bottom face b, each peak on the bottom face a is connected with the close peak on the bottom face b through the edges, each peak of the bottom face a and each peak ofthe bottom face b are separately provided with only one edge and connected with one edge, and the edges comprise the Y-shaped edges. The vascular stent is formed by connecting multiple vascular stentmonomers, except for the two vascular stent monomers located at the head and the tail of the vascular stent respectively, the bottom face a of any one vascular stent monomer is connected with the bottom face a of another vascular stent monomer, and the bottom face b of any one vascular stent monomer is also connected with the bottom face b of another vascular stent monomer.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to a blood vessel stent monomer and a blood vessel stent. Background technique [0002] In vascular stent surgery, an internal stent is placed in the diseased segment to support the stenosis and occluded segment of the blood vessel, reduce the elastic retraction and reshape of the blood vessel, and maintain smooth blood flow in the lumen. In the prior art solutions, the early metal stents have achieved remarkable effects after clinical treatment, but they are prone to cause thrombosis, have a high restenosis rate, and cause vascular wall damage. The newly developed stent grafts and biomaterial stents are degradable materials, and their mechanical properties such as stiffness are obviously insufficient, which will cause the degradable stent to be implanted in the narrow blood vessel, and the insufficient support performance will cause the blood vessel to reappear during its dynami...
