Patent ID: 11633233

Abstract:
The invention relates to a surgical system for cutting an anatomical structure (F, T) of a patient according to at least one target plane defined in a coordinate system of the anatomical structure, comprising: (i) a robotic device (100) comprising: —an end effector (2), —an actuation unit (4) having at least three motorized degrees of freedom, configured for adjusting a position and orientation of the end effector (2) relative to each target plane, —a passive planar mechanism (24) connecting the terminal part (40) of the actuation unit (4) to the end effector (2); (ii) a tracker (203) rigidly attached to the end effector (2), (iii) a tracking unit (200) configured to determine in real time the pose of the end effector (2) with respect to the coordinate system of the anatomical structure, a control unit (300) configured to determine the pose of the end effector with respect to the target plane and to control the actuation unit so as to bring the cutting plane into alignment with the target plane.
