    • The present invention provides a cylindrical surgical stent which is not contracted in an axial direction even during expansion. The invention comprises a ring-shaped stent ring having: a plurality of cells arranged by being spaced in a row in a circumferential direction; and a plurality of first links. The plurality of cells include first curved portions which are convex in a circumferential direction, second curved portions which are concave in a circumferential direction, third curved portions which are convex in an axial direction, and fourth curved portions which are concave in an axial direction. Said first curved portions are respectively connected with the third curved portions and the fourth curved portions, and said second curved portions are respectively connected with the third curved portions and the fourth curved portions. Said first links are formed from a plurality of links, which connect first curved portions and second curved portions of two adjacent cells among the plurality of cells, and have fifth curved portions that are convex in an axial direction. Spots at which the first curved portions and the second curved portions meet the plurality of first links are out of the central axes of the first curved portions and the second curved portions.
    • 本发明提供一种圆柱形外科支架,即使在扩张期间也不会在轴向上收缩。 本发明包括一种环形支架环,其具有:沿圆周方向间隔成一排的多个电池; 和多个第一链接。 多个单元包括沿圆周方向凸出的第一弯曲部分,沿圆周方向凹入的第二弯曲部分,沿轴向凸出的第三弯曲部分和沿轴向凹入的第四弯曲部分。 所述第一弯曲部分分别与第三弯曲部分和第四弯曲部分连接,并且所述第二弯曲部分分别与第三弯曲部分和第四弯曲部分连接。 所述第一连杆由多个连杆形成,所述多个连杆将所述多个电池中的两个相邻电池单元的第一弯曲部分和第二弯曲部分连接起来,并具有沿轴向凸出的第五弯曲部分。 所述第一弯曲部和所述第二弯曲部与所述多个第一连接部相接合的点离开所述第一弯曲部和所述第二弯曲部的中心轴。
