| 摘 要： | 目的改进颈椎间盘假体存在的问题。方法分析自然状态下人体颈椎间盘的功能要求，应用计算机辅助设计(CAD)技术和ANSYS分析手段，优化设计制造由两种高分子材料复合成型、双层结构的新型颈椎间盘假体。结果双层圆柱结构模型(外层为圆柱状纤维环，内层为圆柱状髓核)的颈椎间盘假体具有可以保证上下锥体所受的应力都比较小；正常状态下，可使假体在外部纤维环和内层髓核的最大应力都比较小；该型结构简单，需要的模具结构简单，定位方便准确。结论新型颈椎间盘假体的双层结构为双圆柱结构。

| Abstract: | ObjectiveTo solve some problem in present cervical spinal disc.MethodsAfter analyzing the function of cervical spinal disc, 2 kinds of materials were chosen to design and fabricate the double-layer cervical spinal disc prosthetic. CAD and ANSYS technologies were used to optimize 4 kinds of the new prosthetic structure.Results and ConclusionThe materials if the prosthetic is proper, and the double-layer column structure of the new prosthetic shows some excellence characteristics, including maximum stress of nucleus and annulus properly, simple structure and can be facilitated and exactly graft.
