摘要
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SAS6.12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.
