椎间盘穿刺定位器及其技术的临床应用

Clinical practice of intervertebral dics puncture positioner(IDPP)

目的：研制椎间盘穿刺定位工具，探讨其临床实用性。方法：用三维一面的技术理论、坐标技术、三角函数和绘图基本知识及 Ｃ Ｔ 测量等方法。结果：临床应用本穿刺定位器及其技术，共做１１３例，１２７ 个间盘，其中包括 ３０ 例 Ｌ５ Ｓ１ 间盘突出，仅有最初 ２ 个 Ｌ５ Ｓ１ 间盘穿刺失败，其余均获成功，成功率为 ９８４３％ 。结论：椎间盘穿刺定位器设计合理，操作简单、准确，实用性强，穿刺成功率高。

Objective:To develop the position appliances of intervertebral dics and to study its clinical practicality.Methods:We used the technologic theory of three dimensions and one plat,the coordinate technology,the baxic knowledge of trigonometric function and drafting and the metholds of Ct measure,etc.Results:Through the clinical practice of 113 patients with 127 intervertebral discs,except that the first two cases of L 3 and S 1 failed,the others got success,with the successive rate of 98.43%.Conclusion:The IDPP was designed rationally,operated easily and correctly,and it had large practicality and high success rate.
