针织医用金属内支架的编织工艺研究

Study on Knitting Parameters of Knitted Medical Expandable Metallic Stent

在自行设计研制的小口径针织机上 ,从牵拉张力、弯纱深度、给丝张力等方面探讨了针织医用金属内支架的编织工艺对支架形态的影响规律 ,揭示了编织规律和不同编织工艺条件下的较佳值。

This paper mainly discusses the influences in knitting process such as the taken-down tension, sinking depth and feeding tension. These three factors are separately changed to understand the relationship between the knitting process and the shape of stent. The results show that the knitting technology significantly influences the shape of stent and the optimal knitting parameters were obtained by using the regression method.
