近年来合成纤维缝线和显微缝合针的出现,使眼科手术操作更加完善。但如对这些性能不全了解,术中会出现缝针扭曲、折断,术后缝线松脱等现象,为此笔者结合临床体会做一介绍。一、眼科常用缝合线1、天然纤维①丝线,不能吸收,显微镜下可见表面粗糙,呈螺旋状弯曲,韧性好,感染率较高。②肠线,可吸收,显微镜下粗细均匀,表面粗糙,韧性差,组织反应重,感染率高。2、合成纤维①Dexon,Vicvyl,Po-ldyioxonone,可吸收;②Nylon,Dac-ron,Prolene,不能吸收。合成纤维在显
In recent years, the emergence of synthetic suture and microscopic suture needle, the operation of ophthalmic surgery more perfect. However, such as incomplete understanding of these performance, intraoperative there will be stitches twisted, broken, postoperative suture loose and so on, for which I combined with clinical experience to do an introduction. First, the ophthalmic suture commonly used 1, natural fiber ① silk, can not be absorbed, the surface of the microscope can be seen rough, spirally curved, good toughness, higher infection rates. ② gut, absorbable, uniform under the microscope, the surface roughness, poor toughness, tissue reaction, high infection rate. 2, synthetic fiber ① Dexon, Vicvyl, Po-ldyioxonone, absorbable; ② Nylon, Dac-ron, Prolene, can not be absorbed. Synthetic fibers in significant
