Detailed Description

For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

As shown in fig. 1 and 2:

a vascular stent with strong anti-deformation performance comprises a body, wherein the body is formed by splicing a plurality of annular supporting bodies 1 and a plurality of connecting ribs 2; the annular support bodies 1 are coaxially arranged, and the annular support bodies 1 are sequentially arranged at equal intervals in the axis extending direction; a plurality of splice bar 2 evenly distributed is in the junction of a plurality of

ring support

1, and 2 both ends of splice bar all with ring support 1 fixed connection.

Based on above-mentioned embodiment, medical staff puts into human vascular obliteration department, vascular stent's loop-type supporting body 1 supports with the blood vessel inner wall and contradicts, loop-type supporting body 1 leads to blood blockage with the effectual vascular occlusion of avoiding of vasodilatation, splice bar 2 can effectual improvement vascular stent's pliability, receive the oppression when the blood vessel and produce the deformation, a plurality of splice bars 2 cooperate a plurality of loop-type supporting body 1 effectual change shape, guarantee the circulation of blood vessel simultaneously, when the blood vessel stops the oppression power, splice bar 2 can effectually drive loop-type supporting body 1 and resume the normal position and resume blood vessel smoothness nature simultaneously.
