Introduction:
This study was performed to evaluate the surgical efficiency, localization accuracy, biopsy success rate, and operative safety of three-dimensional (3D) structured-light robot-assisted stereotactic brain biopsy using the Huake Precision SR1-3D system.
Methods:
Clinical data were retrospectively collected from 54 patients who underwent stereotactic brain biopsy in the Department of Neurosurgery, at Jiangxi Provincial People's Hospital between February 2017 and November 2022. Among them, 27 patients underwent frame-based stereotactic brain biopsy using the Anke system, and 27 patients underwent robotic-assisted frame-less stereotactic brain biopsy using the Huake Precision SR1-3D structured-light robot. The registration error of the Sinovation software based 3D structured-light facial scan was assessed. Operative time, diagnostic yield, incidence of adverse surgical events, length of hospital stay, surgical costs, entry-point error, and target-point error were compared between the two groups.
Results:
A total of 54 patients were analyzed, including 27 in the robot-assisted group and 27 in the frame-based group. The mean registration error of the 3D structured-light facial scan was 0.31 ± 0.07 mm. The mean operative time in the robot-assisted group was significantly shorter than that in the frame-based group (p < 0.05). No significant differences were observed in diagnostic yield, postoperative adverse event rate, or length of hospital stay between the groups (all p > 0.05). The surgical costs were higher in the robot-assisted group than in the frame-based group (p < 0.05). The robot-assisted group exhibited smaller entry-point and target-point errors compared to the frame-based group (both p < 0.05).
Conclusion:
This study found that, 3D structured-light robot-assisted stereotactic brain biopsy is associated with shorter operative times and reduced localization error compared to frame-based stereotactic brain biopsy, demonstrating favorable precision and procedural efficiency.
