摘要
目的:研制一种带预警装置的椎弓根螺锥,专门用于椎弓根钉道的准备,克服徒手置钉法的盲目性。方法:该螺锥前端设置的螺杆内置压力感受装置和报警器,术中螺锥方向一旦出现偏差,即刻有声音、灯光双重报警。结果:在即刻的声音、灯光双重报警下,术者可以及时改变进针方向,增加了螺钉置入的准确率。结论:该预警螺锥能有效提高椎弓系统手术的成功率,减少对术者的经验和感觉的依赖程度,避免损伤重要血管、神经。
Objective To design a pedicle piercer with a warning device, which is specifically used for preparation of to screw channel to overcome the blindness of manual operation. Methods The built-in pressoreeeptor and alarming system were placed on the front screw of the piercer. In case of the deviation of the piercer direction during operation, the dual alarm of the voice and lighting appeared instantly. Results With the immediate alarms of the voice and lighting, the operator might change the direction of the piercer in time, which increased the accuracy of the screw placement. Conclusion The piercer with warning device can improve the success rate of traditional pedicle screw fixation and reduce the dependence on the operator.
