Abstract］ objective to explore the accuracy and safety of safety drillprepared for cervical pedicle screw trajectory.methods fourteen adult cadaver specimens of cervical spine（c3～c7）with intact structures including ligaments and perivertebral muscles were reserved and used.according to the radiographic measurements,safety drill was inserted into cervical pedicle individually.the evaluation of the drill's trajectory was carried out by ct scan and three-dimension reconstruction and autopsy.results one hundred and forty drill's trajectories were made.9 holes failed with a perforation rate of 6.4%.conclusion the safety drill prepared for cervical pedicle screw hole is safe and effective and can be applied and popularized clinically.

目的 探索安全钻头应用于颈椎弓根螺钉孔道钻探的安全性与准确性。方法随机取14具福尔马林浸泡的成人颈椎标本（c3～c7），保留完整的脊柱三柱结构及相关的韧带和椎旁肌，根据影像学测量的进钉点和进钉方向，模拟颈椎后路手术过程。选用安全钻头，进行实际的颈椎弓根螺钉孔道的钻探，将孔道行ct扫描，并斜位三维重建孔道形态，并以肉眼直视观察结果为金标准，评价孔道钻探的成败。结果钻探孔道准确率89.3%（125/140），穿孔率6.4%（9/140）。结论安全钻头应用于颈椎弓根螺钉孔道钻探的安全性与准确性均较高，可以在临床上推广使用。
