手指移植的疲劳试验
通常，当整形外科在处理由外伤造成的骨折和软组织伤害时，要用到整形外科用的固定设备,例如， 骨头板，压缩螺钉，固定股骨的钉子等，用它们来提供和维持骨头碎片的整体性。定量化的重要特征量，例如弯曲强度、刚度，这些量可以让外科医生了解手指移植的效果。同时，也使研究人员可以比较该装置的材料和设计的优劣。在最大载荷下，移植手指的疲劳寿命是否超过一定的时间或范围，也必须通过试验把它确定下来。 基于ASTM的指导文献和设备，其试验方法和结果，在应用中是很独特和有效的。ElectroPuls TM 试验系统和8870液压伺服系统两者的共同特点，诸如完整的 t-糟底部，可以固定Dynacell® load cell(即载荷传感器）安装于的作动缸处，以便安装盐浴槽的附件来模拟活体组织，最大程度扩展了研究范围并提高了整体表现。
对于一个小移植体试验，通常是处理指骨,掌骨，和腕骨的断裂，在动载的作用下去验证它的疲劳，抗压盘可被同时设置在ElectroPuls E3000和E1000两款机器上。在简单地刚度调节后，一个弯曲压缩试验在 载荷为0.3-3N，频率为 20HZ设置下运行。这个试验应用了低载荷的 Dynacell 载荷传感器，一个小的压缩板和夹具去
>夹住移植体。并把这一套装置固定安装在
型槽的位置上。
