ABSTRACT
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.
