摘　　要：为了在腰椎退变性疾病保守治疗和融合手术中间地带寻找一种有效的预防与辅助相结合的微创治疗方式,通过对比目前常用的几种腰椎棘突间动态稳定系统的临床疗效观察和优缺点,以及对腰椎棘突间的生理结构、生物力学和相关数据的分析,在充分了解记忆合金材质的基础上,自行设计研究一种记忆合金材料的新型腰椎棘突间动态固定装置,既能重建腰椎的正常生物力学特性,满足人体脊柱的正常活动,又避免对原有结构的破坏,减少术后并发症的发生,同时也可以优化目前的治疗方法。通过研究,腰椎棘突间记忆合金动态稳定装置在理论上效果满意,可以解决现有技术的不足,优于目前的几种腰椎棘突间动态稳定系统。To find an effective method of minimally invasive treatment combining prevention and assistance in the middle zone of conservative treatment and fusion surgery for lumbar degenerative diseases,through the clinical effect observation and the advantage and disadvantage comparison of several commonly used lumbar interspinous dynamic stabilization systems,by analyzing the physiological structure,biomechanics and relevant data of lumbar interspinous processes,based on fully understanding of memory alloy materials,a new dynamic lumbar interspinous fixation device with a memory alloy material has been independently designed and researched,which can not only reconstruct the normal biomechanical characteristics of the lumbar spine and satisfy the normal activities of the human spine,but also avoid damage to the original structure and reduce the incidence of postoperative complications.In addition,the device can be used to optimize the current therapeutic methods.According to our research,the dynamic lumbar interspinous process stabilization device with a memory alloy has theoretically achieved satisfactory results,which can be used to overcome the shortcomings of the existing technology and is superior to the current several dynamic lumbar interspinous process stabilization systems.
