Research on the accuracy of three‐dimensional localization and navigation in robot‐assisted spine surgery

Abstract

Background Compared with traditional surgical methods, which only rely on doctors' experience, three‐dimensional robot‐assisted navigation technology could locate the lesion more accurately. Methods 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. Results 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°). Conclusion 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.

Research on Accuracy of Augmented Reality Surgical Navigation System Based on Multi-View Virtual and Real Registration Technology

“…The introduction of multi-view virtual and real registration method can observe the position of surgical tools and focal points of pathogenesis in real time and monitor the deviation of the whole surgical process. From the experimental data, the accuracy of the ARSN system studied in this paper based on multi-view virtual and real registration is 1.70 0.25  mm, which is 35% higher than that of the previous surgical navigation system that do not use augmented reality [29].…”

“…In this paper, the accuracy of the spinal ARSN system based on multi-perspective virtual and real registration is 1.70 0.25  mm. Without the multi-view virtual and real registration technology in augmented reality, the puncture accuracy of the spinal surgical navigation system developed by our team is 2.54 0.15  mm [29]. In comparison, the puncture accuracy of the entire spinal ARSN system is improved by about 35%.…”

“…Based on the previous research of our team [29], the navigation module of spinal puncture mainly includes four parts: 2D-3D registration, calibration and back projection of calibration target, tracking of spinal reference frame and surgical tools. The transformation matrix 3D…”

“…Four metal balls are inserted into the spinal model to replace the focal points of pathogenesis. In the process of surgery, the existing navigation module of spinal puncture is first used to transform the focal point of pathogenesis and planned surgical paths on the virtual model into the world coordinate system [29]. The robot replaces the human to control the surgical tool to perform the puncture of the simulated surgery.…”

“…On the basis of ensuring the accuracy of the ARSN system, experiments are carried out respectively on the ARSN system and the surgical navigation system without AR [29]. To verify the efficiency and feasibility of the spinal ARSN system.…”
