A number of applications in the surgical practice are based on tensile sutures aimed to keep soft tissues in place and compensate the exit of neuropathies, prolapses or general tissue relaxation. Long-term behaviour of these constructs need to be carefully examined in order to define tensile forces to be applied and to compare different suture anchors. Data here reported refer to equine laryngoplasties, where a suitable loading system has been designed in order to be able to test sutures in-sito, applying known forces ("On-site testing of sutured organs: an experimental set up to cyclically tighten sutures" (Pascoletti et al., 2020 [1])). The loading protocol was made of two steps: in the first step, 3000 loading cycles have been performed; in the following step, a tensile test up to rupture was performed. Cyclic load/displacement curves allow evaluating suture distraction, as a consequence of suture migration and/or soft tissues creep. Tensile curves allow evaluating the residual thread strength and its ultimate displacement. These data can provide a detailed insight of long-term suture behaviour and can be a reference to compare different threads and/or suture anchors.
外科手术中的许多应用都基于张力缝合线，旨在固定软组织并补偿神经病变、脱垂或一般组织松弛的情况。为了确定要施加的张力并比较不同的缝合锚钉，需要仔细研究这些结构的长期行为。此处报告的数据涉及马喉成形术，其中设计了一个合适的加载系统，以便能够在原位测试缝合线，施加已知力（“缝合器官的原位测试：一种循环收紧缝合线的实验装置”（帕斯科莱蒂等人，2020 [1]））。加载方案由两个步骤组成：第一步，进行3000次加载循环；在接下来的步骤中，进行直至断裂的拉伸试验。循环载荷/位移曲线可以评估由于缝合线迁移和/或软组织蠕变导致的缝合线牵张。拉伸曲线可以评估残余线强度及其最终位移。这些数据可以提供对缝合线长期行为的详细洞察，并可作为比较不同线和/或缝合锚钉的参考。
