摘要
对二氧杂环己酮（ＰＤＳ）合成可吸收缝合线及羊肠线的物理特征进行了比较，并通过兔及大白鼠皮下埋植比较ＰＤＳ可吸收缝合线及市售羊肠线体内张力降解及吸收速度，ＰＤＳ合成线的强度与相同型号的羊肠线相似。ＰＤＳ缝合线在５６天时已全部吸收，张力降解也比较符合生理要求，某些物理特性（可塑性、物理形状稳定性及表面光滑性）优于目前市售的羊肠线。
The properties of PDS synthetic absorbale suture and catgut were compared. The velocity of absorbability and tension degradation were compared by implanting PDS absorbable suture and catgut. The strenght of PDS suture is similar to that of catgut of the same diameter. PDS was complete absorbed after 56 days, and the tension degradation also met the biological requirement better. Some properties (plasticity, stability of physical shape, surface smoothness) are better thanthe catgut available on the market.
