目的    探讨个体化“三定式”导向器辅助椎间孔镜手术治疗腰椎间盘突出症的临床意义。  方法    根据纳入和排除标准，选取2021年12月~2022年11月腰椎间盘突出症患者16例，随机分为两组，对照组（n=8）采用传统手术方法；实验组（n=8）利用团队自主设计的个体化“三定式”导向器辅助椎间孔镜手术，术前采集患者CT数据导入软件进行个体化设计，模拟手术穿刺路径，拟定进针位置、进针角度、进针深度（即“三定”），术中将个体化“三定式”导向器置于体表，根据修正值调整穿刺角度和方向，实现精准穿刺。比较两组透视次数、穿刺时间、穿刺次数。  结果    实验组透视次数、穿刺时间、穿刺次数均少于对照组，具有统计学意义（P<0.01、P<0.01、P<0.05）。  结论    应用个体化“三定式”导向器辅助椎间孔镜手术治疗腰椎间盘突出症切实可行，效果良好。

Objective   To explore the clinical effect of individualized "three-set" guide assisted endoscopic lumbar  discectomy in the treatment of lumbar disc herniation.    Methods    According to the inclusion and exclusion criteria, 16 patients with lumbar disc herniation from December to November were selected and randomly divided into two groups. The control group (n=8) was treated with traditional methods. The experimental group (n=8) was assisted by the individualized "three-set" guide in intervertebral foramen surgery. The CT data of patients were collected and imported into the software before operation to conduct individualized design, simulate the surgical puncture path, and determine the needle insertion position, needle insertion angle and needle insertion depth (referred to as "three-set"). The individualized "three-set" guider was placed on the body surface, and the puncture angle and direction were adjusted according to the correction value, and the accurate puncture was realized by the guider. The times of fluoroscopy, puncture timing and puncture frequency of the two groups were recorded and statistically analyzed.  Results  The times of fluoroscopy, puncture timing and puncture frequency of the experimental group were less than those of the control group, with statistical significance (P<0.01,P<0.01,P<0.05).    Conclusions    It is feasible and effective to use the individualized "three-set" guide to assist intervertebral foramen surgery in the treatment of lumbar disc herniation.
