中文摘要:
      骨科缝合线是肌腱、韧带修复手术中非常重要的医疗器械之一,其性能尤其是力学性能,对于修复的成败影响很大。通过检索国内外骨科缝合线方面的文献,首先总结临床上常用的骨科缝合线,包括可吸收和非可吸收缝合线,以非可吸收缝合线为主。然后,针对骨科缝合线使用部位的特殊性,重点综述骨科缝合线体外力学性能测试与评价方法 ,主要涉及缝合线本身、缝合线与组织之间以及缝合线与锚钉之间的力学行为测试装置与评价方法 ,并分析不同装置或方法 的特点。由于缺乏统一的测试仪器与评价标准,目前尚难以对骨科缝合线的力学性能进行统一的评价比较。
英文摘要:
      Orthopedic sutures are vital medical devices in repair surgeries of tendons and ligaments. Properties especially mechanical properties of orthopedic sutures have great impacts on the effects of tendon/ligament repairs. In this paper, clinically used orthopedic sutures including absorbable sutures and non-absorbable sutures were summarized firstly, by exploring literature about orthopedic sutures, and the mostly used orthopedic sutures are non-absorbable sutures. Then, based on the particularity of the repaired sites of orthopedic sutures, the in vitro mechanical test devices and evaluation method of orthopedic sutures were reviewed, mainly including the mechanical properties of sutures, suture-tissue, and suture-anchor. In addition, the characteristics of different evaluation method or test devices were compared. It was still difficult to evaluate the mechanical properties of orthopedic sutures due to the lack of instruments and test criteria.
