兔无骨折脱位型颈脊髓挥鞭伤致伤平台的研制

Development of Cervical Spinal Cord Whiplash Injury Without Dislocation Platform for Rabbit

目的研制物理参数可控的简易致伤平台,从而实现挥鞭伤研究从静态到动态全方位模拟,为交通伤动物实验提供新的简易实验装置。方法在现有生物力学实验室基础上,研制简易摆锤及框架结构、动物固定台车、滑动轨道等装置,充分利用实验室现有设备,建立可以用于小动物的致伤平台。结果空载碰撞和追尾实验均未见小型台车结构及轨道发生变形和损坏,碰撞过程中兔颈椎产生了挥鞭样动作。结论兔无骨折脱位型颈脊髓挥鞭伤致伤平台与生物力学实验室目前现有条件匹配良好,满足实验要求。

Objective To aim at development of simple platform which physical parameter can be controlled, and realize the whole simulation of cervical spinal cord whiplash injury without dislocation in dynamic condition. Methods Based on present condition of lab, simple devices were developed. Existing equipment were used to establish a platform for small animal injury. Results The structures of sled and rail were not damaged in no-load crash and collision experiments. Whiplash movement of rabbit cervical spine occurred during crash. Conclusion The injury platform matched present condition of lab well. Different collision conditions were duplicated using pendulum bob. This platform had been rationally designed. It could stimulate many traffic processes.
