Abstract
Compared with traditional surgical methods, which only rely on doctors' experience, three-dimensional robot-assisted navigation technology could locate the lesion more accurately. The transformation principle of three-dimensional navigation system was analyzed. The surgical path was planned on the reconstructed three-dimensional model. The experimental data of positioning position and posture were used as two important parameters to evaluate the accuracy of the robot-assisted spine surgery navigation system. The final experimental results show that the accuracy of the positioning and navigation position of the robot-assisted surgical navigation system was 2.54 ± 0.15mm (range 2.25-2.76 mm). The accuracy of positioning and navigation posture was 2.55 ° ± 0.49°(range 1.92°-3.21°). It could be seen the three-dimensional positioning and navigation system proposed in this study had a high accuracy and could basically meet the basic accuracy requirements of spine surgery.
