摘要
研究不同捻度缝合线的浸润效果,通过SEM(扫描电子显微镜)观察不同捻度缝合线浸润树脂后的尺寸及其与树脂界面结合情况.研究结果表明:随着缝合线捻度的增加,树脂浸润缝合线的效果变差,缝合线纤维束及单丝与树脂结合情况变差;浸润树脂后的缝合线纤维束尺寸相对浸润之前提高,但随着捻度的增加,浸润树脂后的缝合线纤维束尺寸降低.
An accurate assessment of the axial permeability of sewing thread with different twists was presented.Meanwhile,the dimensions of the sewing threads with different twists and their interface with resin were discussed by the scanning electron microscope technology.The experimental results show that the increasing of sutures’ twist degrades the permeability along the axial direction of sewing thread and dimensions of sutures’ cross-section decrease while the interface of sewing thread and resin deteriorate with increasing the twist of the sewing thread.However,the dimensions of sutures after infiltration of resin are greater than before.
