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： Kits and methods for use in intraoperative trialling of hip prostheses to determine an appropriate length for the femoral neck component of a prosthetic hip joint, are described. A kit for use in selecting a femoral neck component of an orthopaedic joint prosthesis kit comprises a first and a second broach. Each of the first and second broaches has a neck connection element comprising a projection extending from a proximal surface of the broach, each projection having a length. The projection on the first broach has a different length than the projection on the second broach. The kit also includes a trial femoral neck component having a neck connection element in the form of a recess in a distal surface. The recess is configured to mate with the projection on each of the first or second broaches such that mating of the trial femoral neck component with the first broach provides an assembly with a first neck length, and the mating of the trial femoral neck component with the second broach provides an assembly with a second neck length.
