目的:评价应用surgView-RFT电磁导航系统进行卵圆孔穿刺的准确性及对临床的指导意义.方法: 3 名初学者分别对3 个尸头的双侧卵圆孔进行盲穿和电磁导航辅助穿刺各5 次,以CT扫描结果作为金标准,测量穿刺针尖与卵圆孔前缘的距离,采用SAS 6.12统计软件的t检验和方差分析进行分析.结果: 3 名实验者盲穿均未进入卵圆孔,针尖与卵圆孔前缘平均间距8～10.6 mm;电磁导航辅助穿刺均进入卵圆孔,针尖与卵圆孔前缘平均间距2.68～3.54 mm,与CT比较误差0.59 mm,差异无显著性;盲穿与导航辅助穿刺差异存在显著性.结论:surgView-RFT电磁导航系统操作简便省时,可提高穿刺准确性,有助于避免重复穿刺和减少创伤.

Objective: To evaluate the surgView-RFT electromagnetic navigation system in radiofrequency thermocoagulation(RFT). Methods: 6 foramen ovales of 3 cadavers were punctured by 3 beginners. Every one tried 5 times by free-hand and 5 times by SurgView-RFT electromagnetic navigation-guidance. After each puncture, CT scans were used as golden standard to measure the distance between the tip of needle and the anterior margin of the foramen ovale. T test and variance of SAS 6.12 statistical software was used to do the statistic analysis. Results: The punctures by free-hand failed, and the distances between the tip of needle and the anterior margin of the foramen ovale were 8-10.6 mm. The punctures by navigation guidance were successful, and the distances between the tip of needle and the anterior margin of the foramen ovale were 2.68-3.54 mm. The error of navigation system was 0.59 mm which was verified by CT scan. There was significant difference between free-hand puncture and navigation-guided puncture. Conclusion: The surgView-RFT electromagnetic navigation system is characteristic with high performance, high accuracy and minimal invasion, while it is applied in training or clinical using.
