Background The purpose of this study was to define the technical requirements of future (tele)robotic neurosurgical systems. We aimed to analyse the movements of surgical instruments during neurosurgical procedures. Methods A commercially available neuronavigation system (StealthStation TREON plus , Medtronic, USA) was used to determine the position and orientation of the surgical instrument. A custom‐made log‐mode was implemented in the software to file instrument coordinates intraoperatively. Data was collected during the debulking of malignant primary brain tumours, temporal epilepsy surgery and skull base tumour surgery. Results Maximum tip displacement velocity varied, per procedure, in the range 6.6–12.7 cm/s and maximum rotational speed 21–40 /s. Maximum instrument orientation differences within the volume of movement varied. The largest differences were detected during temporal epilepsy surgery (73° and 52° in the coronal and axial planes, respectively), while the smallest differences were detected in the debulking of an intraventricular tumour. Conclusions In this study, we have demonstrated the feasibility of motion analysis in image‐guided neurosurgery. To mimic ordinary open neurosurgery, future neurosurgical (tele)robotic systems should at least support translational speeds up to 12.7 cm/s, rotational speeds up to 40 /s and differences in instrument orientation of up to 73 .
