摘要： The invention relates to a system for guiding a surgical tool (200) held by a user relative to at least one target axis (T) defined in a coordinate system of a patient's spine, comprising: (i) a robotic device (300) comprising: —a base (301), —a guiding device (303) configured for constraining the tool to a guiding axis (G), —a compact motorized actuation unit (304) movable relative to the base (301), coupled to the guiding device (303) for adjusting a position and orientation of said guiding device relative to the target axis, —a support unit (305) connected to the base (301), comprising at least one element designed to make contact with the spine or a region of the patient's body adjacent to the spine so as to provide a partial mechanical link between the guiding device and the spine, (ii) a passive articulated lockable holding arm (400) supporting the base (301) of the robotic device, (iii) a tracking unit (500) configured to determine in real time the pose of the guiding axis with respect to the coordinate system of the patient's spine, (iv) a control unit configured to: (a) determine the pose of the guiding axis with respect to the target axis, (b) compute a working space of the robotic device for said determined pose, (c) compute at least one indicator representing the capability of the actuation unit to bring the guiding axis in alignment with the target axis based on the computed working space and the pose of the guiding device, (v) a user interface (600) coupled to the control unit, configured for displaying a representation of the guiding axis (G) relative to the target axis (T), wherein the control unit is further configured to control the actuation unit to bring the guiding axis into alignment with the target axis.

摘要： An orthopaedic knee prosthesis includes a femoral component having a condyle surface. The condyle surface is defined by one or more radii of curvatures, which are controlled to reduce or delay the onset of anterior translation of the femoral component relative to a tibial bearing.

摘要： An orthopaedic prosthesis system includes a femoral component configured to be attached to a distal end of a patient's femur. A tibial tray is configured to be attached to a proximal end of a patient's tibia. A tibial insert is configured to be positioned between the femoral component and the tibial tray. An elongated pin rotatably couples the tibial insert to the femoral component.
