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
