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: —a cutting tool, —an actuation unit (4) comprising from three to five motorized degrees of freedom, said actuation unit comprising at least one portion having a parallel architecture comprising a base (40) and a platform (41) selectively orientable relative to the base (40) according to at least two of said motorized degrees of freedom, —a planar mechanism (24) connecting a terminal part of the actuation unit (4) to the cutting tool (2), ii) a passive articulated lockable holding arm (51) supporting the actuation unit, iii) a tracking unit (200) configured to determine in real time the pose of the cutting plane with respect to the coordinate system of the anatomical structure, iv) a control unit (300) configured to determine the pose of the cutting plane with respect to the target plane, to detect whether the cutting plane can be aligned with one target plane without changing the pose of the actuation unit, the control unit being further …
