ABSTRACT
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.
