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 respec

Abstract: The invention relates to a system for positioning a surgical device, said surgical device comprising: a base (1) designed to be held in a user's hand, an end-effector (2) for mounting a surgical tool, respectively a guide (20) for guiding a surgical tool (3), said surgical tool being designed to treat a planned volume of a part (P1) of a patient's body, an actuation unit (4) connected to said base (1) and said end-effector (2) for moving said surgical tool (3), respectively tool guide (20), with respect to the base (1) in order to treat said planned volume, said positioning system comprising: (i) a tracking unit (200) configured to determine in real time the pose of at least one of the tool (3), the end-effector (2) and the base (1) with respect to the part to be treated, (ii) a control unit (300) configured to: (a) compute in real time the working space of the surgical tool for said determined pose, (b) compute in real time the volume that remains to be treated to achieve the treatment of the planned v

Abstract: The invention relates to a method for constructing a patient-specific surgical guide comprising at least one contact element comprising a contact surface intended to match an anatomical structure to be treated in view of implantation of an implant and at least one guiding element for guiding a surgical instrument to treat said anatomical structure, said method comprising: receiving a non-segmented 3D medical image of the anatomical structure of the patient; determining, in said non-segmented 3D medical image, anatomical references of the patient; based on said anatomical references, positioning an implant model in the non-segmented 3D medical image; adjusting at least one of: a type, a size, a position and an orientation of the implant model with respect to the anatomical structure in the non-segmented 3D medical image; recording planning data including said adjusted type, size, position and orientation of the implant model; using a patient-specific surgical guide adapted to carry out implantation of the i
