镍钛诺(Nitinol)是一种具有形状记忆效应的合金。它在明显的塑性变形之后,在一定温度条件下又可回复到它变形前的原始形状。我科通过动物实验,进一步证实了镍钛诺记忆合金不仅具有上述各种特性,而且有特别优良的生物相容性。自1981年11月起,根据镍钛诺记忆合金的记忆形状效应,设计了一种波形弯脚骑缝钉应用于临床,同定植骨端取得较好效果,兹报道如下: Nitinol is an alloy that has a shape-memory effect. After obvious plastic deformation, it can return to the original shape before deformation under a certain temperature condition. Our department through animal experiments, further confirmed that Nitinol memory alloy not only has the above characteristics, but also has particularly good biocompatibility. Since November 1981, according to the memory shape effect of Nitinol memory alloy, a curved foot curved staple designed for clinical use, with the bone graft to achieve better results, it is reported as follows:
