Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0013] Such as figure 1 As shown, a vascular stent, the vascular stent is tubular, including a plurality of metal elliptical mesh ring units distributed along the axial direction, the mesh ring unit is composed of a plurality of tightly connected mesh rings 1, each mesh The ring units are connected by a connecting piece 2, and the connecting piece 2 is a double helix structure, and the double helix structure is formed by winding two S-shaped metal pieces with opposite rotation directions.

[0014] Preferably, the connectors 2 are evenly spaced between the mesh ring units.

[0015] Preferably, the ratio of the long diameter to the short diameter of the elliptical mesh ring unit is 3:2.

[0016...

Abstract

The invention discloses a vascular stent. The vascular stent is shaped like a tube and comprises a plurality of metal oval net ring units which are axially disposed. Each net ring unit is composed of a plurality of closely connected net rings. The net rings are connected through connectors. Two S-shaped metal parts rotating oppositely intertwine to form each connector of a double spiral structure. According to the arrangement, two S-shaped metal parts rotating oppositely intertwine to form each connector of the double spiral structure, thus high supporting force is achieved, and the vessel is protected from narrowing.

Description

technical field [0001] The invention relates to a blood vessel stent, which belongs to the technical field of medical instruments. Background technique [0002] Vascular stent refers to the placement of internal stents in the diseased segment on the basis of lumen balloon expansion to support the stenotic and occluded segment of the vessel, reduce elastic recoil and reshaping of the vessel, and maintain smooth blood flow in the lumen. Some internal stents can also prevent restenosis. Mainly divided into coronary stents, cerebrovascular stents, renal artery stents, aortic stents, etc. However, the supporting force of the existing vascular stent is insufficient, and the coverage rate of the metal surface is small, which easily causes vascular restenosis. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a vascular stent with strong supporting force to prevent restenosis of blood vessels...
