    Abstract: An interface apparatus (20) for tracking by a tracking system (40) of an object(s) in space for position and orientation and for interacting with the tracking system (40). The interface apparatus (30) comprises passive detectable devices (12,14,16,22) trackable for position by the tracking system (40). A mounting device (10,24) receives the passive detectable devices (12,14,16,22) in a known geometry, and is secured to the object(s) such that a position and orientation of the object(s) is calculable by the tracking system (40) as a function of a tracking of the known geometry of the passive detectable devices (12,14,16,22). One of the passive detectable devices (22) is displaceable with respect to the object(s). A displacement of the passive detectable device (22) with respect to the object(s) is detectable to initiate an interaction with the tracking system (40) while maintaining the tracking of the object(s).

    Abstract: A drill guide assembly (10) for a drilling tool (50) having a chuck engaging a bit portion (54) comprising a tip (62) and a length extending from the chuck, the drill guide assembly comprising a first member (14), a second member (12) and a trackable member (16). The first member (14) is adapted to abut a workpiece surface and defines a central aperture (19) therethrough adapted to receive the bit portion. The second member (12) is adapted to be axially displaced with respect to the first member and is axially biased therefrom, and defines a central aperture (11) therethrough adapted to receive the bit portion. The trackable member (16), fastened to the second member, comprises a detectable element (35) adapted to be located and tracked in three dimensional space, thereby defining the position and movement of the second member and therefore that of the drilling tool bit portion.

    Abstract: A system for automatic calibration of instruments (S) having varying cross-sectional dimensions within a predetermined range and having detectable elements (110, 112, 113, 114) thereon for computer-aided surgery, comprising a calibration base (C) having detectable elements (43, 44, 46, 48) secured thereto for detecting a position and an orientation thereof in space by sensors (204) connected to a position calculator (202). The calibration base is adapted to receive and to releasably secure a working shaft (100) of any of the instruments (S) and provides an abutting surface (14) for a tip (102) thereof in such a way that a position and orientation of the tip (102) of the instrument (S) secured therein is calculable when working shaft cross-section dimensions thereof are known. The position calculator (202) receives instrument data (214) and calibration data (218) from an operator through a user interface (206) and stores the instrument data (214) and calibration data (218) for subsequent calibrations.

    Abstract: A computer-assisted surgery system has inertial sensor unit connected to an instrument and producing readings representative of its orientation. A computer-assisted surgery processor unit has a coordinate system module for setting a pelvic coordinate system from readings of the inertial sensor unit when the instrument is in a given orientation relative to the pelvis, a tracking module for tracking an orientation of the instrument relative to the pelvic coordinate system during movements thereof and a geometrical relation data module for recording preoperatively a landmark orientation relative to the pelvic coordinate system and a distance when the at least one instrument has a first end abutted to a pelvic landmark and a second end abutted to a leg landmark, for recording after implant rejointing the medio-lateral orientation and the distance, and for calculating a leg length discrepancy and/or an offset, based on the distances and the medio-lateral orientations.
