聚对二氧环己酮医用可吸收缝合线纺丝工艺研究

以聚对二氧环己酮为原料熔融纺制缝合线,研究了纺丝工艺对缝线的性能影响,结果表明,在室温和80℃进行两次拉伸所得缝线力学性能比较理想;70～100℃进行定长热定型,可在非晶区形成明显的微晶结构;在理想的工艺条件下纺制的缝线力学性能达到美国药典第22版要求.

Synthetic Absorbable Surgical Sutures

This paper reviewed all types of the polymer - based synthetic absorbable surgical sutures that have been commercially produced. The chemical component, biological and mechanical properties, and using effect of these sutures were discussed. The recent development and the possible coming research orientation in these areas were also presented.
