To introduce a new broken pedicle screw fragment retrieval instrument, and evaluate its clinical viability and effectiveness.
Following basic retrieval contrivance of broken pedicle screws described in literature, a new retrieval instrument was designed and developed; introducing its mechanism, technical components, and use. This innovative apparatus proved successful not only in saw bone and cadaver trials but in 10 clinical cases as well.
This particular unique instrument successfully retrieves broken pedicle screw fragments through original passage backing out the screw with preservation of pedicle integrity while maintaining pedicle biomechanics. No complications were observed.
With solid scientific theoretical planning and experimentation, the new retrieval instrument design proved clinical practicality and efficacy.
介绍一种新型的折断椎弓根螺钉碎片取出器械，并评估其临床可行性和有效性。
根据文献中描述的折断椎弓根螺钉的基本取出装置，设计并开发了一种新的取出器械；介绍其机制、技术组件和使用方法。这种创新器械不仅在锯骨和尸体试验中取得成功，在10例临床病例中也取得了成功。
这种独特的器械通过原始通道成功取出折断的椎弓根螺钉碎片，在保持椎弓根完整性的同时退出螺钉，同时维持椎弓根生物力学。未观察到并发症。
通过扎实的科学理论规划和实验，新的取出器械设计证明了其临床实用性和有效性。
