Description

一种用于埋线提拉的锯齿缝合线（带刺）及其制作方法
技术领域
本发明涉及整形技术领域，特别涉及一种用于埋线提拉的锯齿缝合线（带刺）及其制作方法。
背景技术
现有的缝合线，切割的锯齿角度都是45度，同时对生的双向锯齿结构长度是1：1的，从力学的角度看，45度锯齿角受力不均匀，会出现应力集中，进而使结构发生破坏，最终限制缝合线的提拉效果。
通过数值仿真系统，我们对45 度锯齿角的缝合线进行了数字建模、设置约束、施加荷载，数值计算,最终得出結果，在施加荷载以后，45 度缝合线发生了变形，且变形程度大，同时现在手术中的缝合线的固定端长度小于提拉端，缝合线植入皮肤之下后，提拉端无法有效提拉下垂的软组织及周边肌肉，而固定端不能为提拉段提供支持力。
发明内容
针对上述缝合线的不足，本发明的目的提供一种用于埋线提拉的锯齿缝合线（带刺）及其制作方法。
本发明的技术方案是这样实现的：
本发明用于埋线提拉的锯齿缝合线（带刺）,由线体和锯齿组成，要点在于线体和锯齿一体加工而成，线体和锯齿的夹角为25度。
本发明锯齿缝合线（带刺）的制作方法，线体和锯齿一体加工切割而成，线体和锯齿的夹角为0度至45度，优先采用25度夹角。
本发明的有益效果是：锯齿缝合线（带刺）植入组织后，相对滑动较小，提升了提拉效果，同时25度锯齿夹角的设计也提高了线性提拉效果，减小了变形。
附图说明
图1为本发明的结构示意图；
图中：1线体、2锯齿。
具体实施方式
下面结合实施例对本发明做进一步的说明。
本发明用于埋线提拉的锯齿缝合线（带刺）由线体1和锯齿2组成，线体1和锯齿2一体加工而成，线体1和锯齿2的夹角为25度；本发明锯齿缝合线（带刺）的制作方法，线体1和锯齿2一体加工切割而成，线体1和锯齿2的夹角为0度至45度，优先采用25度夹角；缝合线植入皮肤之下后，提拉端的作用是提拉下垂的软组织及周边肌肉，而固定端则为提拉端提供支持力，所以对于固定端，我们自然希望它相对滑动较小，以实现最大提拉效果，在拉力荷载相同且缝合线总长度固定的情况下，适当增加固定端的长度，能够使得固定端单位长度上受力减小，进而减小相对滑动，保证最佳提拉效果，在延长固定端长度之后，固定端锯齿尖端的相对滑动减少了约 40%；由此可知，缝合线的固定端长度必须长于提拉端。
