Embodiment 1
[0034] refer to figure 1 As shown, the stent 10 provided by an embodiment of the present application includes a plurality of support unit rings 1 and a plurality of connecting rods 2, and the plurality of connecting rods 2 connect the plurality of support unit rings 1 along the axial direction 10c of the stent 10 into a For the network tubular structure, understandably, the extending direction of the central axis of the formed network tubular structure is the axial direction 10c of the stent 10 . structure figure 2 As shown, after a plurality of support units are connected by a plurality of connecting rods 2 to form a network tubular structure, when viewed along the axial direction 10c of the stent 10, it will be in the shape of a ring, that is, it has an opposite inner surface 10a and an outer surface 10b, the stent The wall thickness h of 10 is the distance between the inner surface 10a and the outer surface 10b.

Embodiment 2
[0075] The bracket 10 of this embodiment is the same in composition and connection as in Embodiment 1, except that the number of first turning parts 12 or second turning parts 13 is 9-12, for example 9, 10, 11 or 12. The number of connecting rods 2 is 3-5, such as 3, 4 or 5. The stent 10 formed in this way can adapt to blood vessels with larger diameters and has excellent expandability.
Embodiment 3
[0077] Such as Figure 7 As shown, the structure of the supporting unit ring 1" of the bracket 30 in this embodiment is the same as that of Embodiment 1, and only the structure of the connecting rod 2" is different. Specifically, in the bracket 30 in this embodiment, the connecting rod 2" adopts Relatively smooth structure. The connecting rod 2” includes multiple arc segments, except that the arc segment at the position connected to the support unit ring 1” has obvious curvature, and the radius of curvature is 0.05mm to 0.15mm, such as 0.05mm, 0.1mm Or 0.15mm. The radius of curvature of the arc section in other places is relatively large, and they are connected smoothly. This makes the crimping diameter of the stent 30 smaller, and improves the lesion-passing ability and pushing ability of the stent 30 .
