Abstract
This paper presents a novel system for accurate placement of pedicle screws, jointly developed by the German Aerospace Center and BrainLAB. The system consists of a light-weight (< 10 kg), kinematically redundant, and fully torque controlled robot. Additionally, the pose of the robot tool-center point is tracked by an optical navigation system, serving as an external reference source. Therefore, it is possible to measure and to compensate deviations between the intraoperative and the preoperatively planned pose. The robotic arm itself is impedance controlled. This allows for a new intuitive man-machine-interface as the joint units are equipped with torque sensors: The robot can be moved just by pulling/pushing its structure (i.e. haptic interaction). The surgeon has full control of the robot at every step of the intervention. The hand-eye-coordination problems known from manual pedicle screw placement can be omitted.
