Objective:To study the efficiency and safety of domestic Remebot robot (neurosurgical positioning and navigation system) in the resection of craniocerebral microlesions and functional area lesions.Methods:Twelve patients accepted resection of craniocerebral microlesions and functional area lesions in our hospital from October 2021 to March 2022 were chosen in our study; navigation, localization and resection of craniocerebral microlesions and functional area lesions were performed with assistance of Remebot robot. Surface Markers were used for optical registration during the surgery, and the registration error was recorded in detail. Scalp incision and bone flap boundary were designed by laser navigation. Postoperative head CT and MRI scan were performed to observe intracranial hemorrhage and lesion resection. The postoperative image was fused with the preoperative surgical plan to calculate the deviation between the planned and actual flap centers.Results:The patient registration error was 0.6-1.5 mm, with an average of (0.9±0.12) mm. The registration error of the manipulator was 0.09-0.12 mm. Preoperative and postoperative image fusion showed that the deviation between the planned and actual flap centers was 1.4-4.5 mm, with an average of (1.9±1.1) mm. All surgical procedures were performed with robot laser navigation to find the lesion boundary along the planned path at one time, which was less destructive to the cortex and surrounding tissues. Postoperative head CT or MRI examination showed that all lesions were completely resected. No serious complications occurred in these 12 patients.Conclusion:Domestic robot can provide precise localization and navigation function for the resection of craniocerebral microlesions and functional area lesions, improving the surgical efficiency and ensuring the safety of surgery.
