新型医用颈椎置钉定位系统的研究

Study about a New Medical Position System for the Cervical Pedicle for Screw Placement

介绍了一种新型医用颈椎椎弓根螺钉置钉定位系统。该系统由图形矢量化软件、绘图软件、可视化计算软件及可三维调节的定位器、角度校验装置组成,克服了现行置钉方法的缺点,提高了置钉的准确率,降低了手术的难度与危险性。

A new medical position system being used for cervical pedicle for screw placement is introduced. The system is composed of graph vectorization software, drawing software, visual calculating software, position device which can he modulated at the three dimensions and sine dividers which is used to test the angles. The application of this system would not only overcome the shortcomings of the current methods for screw placement but also improve the accuracy and safety as well as reduce the degree of difficulty during operation.
