摘  要:缝线在锚钉孔眼处磨损断裂是带线锚钉临床失效的主要原因,但由于缺乏测试装置,对缝线耐磨性的定量评价及影响因素尚不明晰。通过自主设计并搭建缝线摩擦性能测试装置,选取几种常用的缝线与锚钉,调节缝线拉伸角度(θSA)与锚钉旋转角度(θARA),对其断裂强力及耐磨性进行测试。结果表明:搭建的测试装置可为缝线耐磨性测试提供定量数据比较;聚对二氧环己酮由于其更高的断裂强力和单股结构,耐磨性最佳;锚钉孔眼表面的线槽设计会使缝线耐磨性降低,且线槽尺寸越大,对缝线耐磨性的损伤越大;与θSA为45°相比,θSA为0°时缝线表现出更好的耐磨性,对于无线槽锚钉,θARA为90°时缝线耐磨性更好,对于有线槽锚钉θARA为0°时缝线耐磨性更好。Suture anchors often fail in service due to the abrasion and fracture of suture at the interface between suture and anchor eyelet in clinic.However,the quantitative evaluation of the abrasion resistance of suture is still unascertained owing to the absence of an measurement technique.A abrasion testing device was constructed,and several commonly used sutures and anchors were selected for this experiment.The breaking force and abrasion resistance of the sutures were analyzed by altering the suture-pull angle(θSA)and the anchor rotation angle(θARA).The results show that the abrasion device could provide quantitative comparisons for different sutures.The monofilament structure of poly(p-dioxanone)suture demonstrates the highest breaking strength and exhibits superior abrasion resistance.The groove on the anchor eyelet surface results in inferior abrasion resistance,and the larger the groove size,the higher the abrasion resistance.The suture shows lower abrasion resistance atθSA=0°compared with that atθSA=45°.For the anchor without groove,the suture displayed higher abrasion resistance atθARA=90°.In contrast,for the anchor with groove,the suture showed higher abrasion resistance atθARA=0°.
