Neurosurgical robot‐assistant stereoelectroencephalography system: Operability and accuracy

BACKGROUND: Fine operation has been an eternal topic in neurosurgery. There were many problems in functional neurosurgery field with high precision requirements. Our study aims to explore the operability, accuracy and postoperative effect of robot‐assisted stereoelectroencephalography (SEEG) in neurosurgery. METHODS: We conducted a retrospective analysis of patients with epilepsy who underwent electrode implantation in our hospital. From 2016 to 2019, the epilepsy center of Hebei people's hospital implanted electrodes in neurosurgery on 24 patients, including 20 with SINO robot‐assisted SEEG system and eight with frame‐SEEG technology. RESULT: Robot‐assisted SEEG neurosurgery had higher accuracy, and the mean error of entry and target point was smaller than that of frame SEEG surgery. No bleeding or infection occurred postoperatively, and two patients who underwent robot‐assisted SEEG neurosurgery had electrode displacement. Electrode displacement was observed in two patients, both the entry points were orbital frontal, one in the frame system and one in the robot assistant system. The average placement time of each electrode in robot assisted system surgery was less than that in frame system surgery. CONCLUSION: The SINO SEEG electrode implantation assisted by surgical robot‐assistant system manufactured in China is safe, accurate and mature.
