Title: (ZH) 拱弧流线型人体管腔网状圆筒支架
Abstract: front page image
(ZH)

拱弧流线型人体管腔网状圆筒支架,将每一组梁柱设计为以拱弧峰谷顶端形状,由流线波浪连接峰、谷;以垂直于轴向的圆周线为峰、谷交替的波浪曲线中心线,同一组梁柱波浪线是以平行于纵轴为波幅的主波峰、次波峰两种的峰、谷交替的波浪连续波浪闭合线,中心线单侧的波峰个数N=4+2a个,除端口而外,每一组梁柱内由两种不等波幅的主、次峰间隔排列,组与组之间采用S形桥筋主峰接连,圆筒网状支架在端口的两组梁柱单元中不分主、次峰,每个波幅是相等的;将相邻梁柱组中的主波峰相向连接,用S型桥筋实现,次波峰不受桥筋连接,S桥筋与相向主幅波峰梁柱内缘圆顺过渡,没有锐角形成。径向支撑力好,径向回缩率小;轴向顺应性好,柔韧性好,轴向收缩小,侧壁窗口大,侧肢整形好,金属覆盖分布得当,耐疲劳性好。
