Abstract
Described are surgical systems comprising a robotic device comprising a cutting tool, an actuation unit having at least two motorized rotational degrees of freedom about respective rotational axes that are substantially orthogonal to each other, and configured for adjusting a position and orientation of the cutting tool relative to each target plane, a planar mechanism connecting the last segment of the actuation unit to the cutting tool, a passive articulated lockable holding arm supporting the actuation unit, a tracking unit configured to determine in real time the pose of the cutting plane with respect to the coordinate system of the anatomical structure, a control unit configured to determine the pose of the cutting plane with respect to the target plane and to control the actuation unit to bring the cutting plane into alignment with the target plane.
