    摘要： A tool for digitizing a mechanical axis of a tibia using a computer-assisted surgery system is described. The tool includes upper and lower mounting ends interconnected by an alignment rod extending therebetween. The upper mounting end is releasably fastenable to an upper reference point on a tibial plateau and the lower mounting end includes a self-centering malleoli engaging mechanism having opposed caliper arms displaceable in a common plane relative to each other for clamping engagement with the medial and lateral malleoli of the ankle. At least one trackable member is mounted to the alignment rod of the tool and is in communication with the computer assisted surgery system for providing at least orientation information of the alignment rod. The mechanical axis of the tibia is parallel to the alignment rod and extends between the upper and lower reference points when the tool is mounted on the tibia.

    摘要： A computer-assisted surgery system for planning/guiding alterations to a bone in surgery, comprises a trackable member adapted to be secured to the bone. The trackable member has a first inertial sensor unit producing orientation-based data for at least two degrees of freedom in orientation of the trackable member A positioning block is adapted to be secured to the bone, with at least an orientation of the positioning block being adjustable once the positioning block is secured to the bone to reach a selected orientation at which the positioning block is used to guide tools in altering the bone. The positioning block has a second inertial sensor unit producing orientation-based data for at least two degrees of freedom in orientation of the positioning block. A processing system providing an orientation reference associating the bone to the trackable member comprises a signal interpreter for determining an orientation of the trackable member and of the positioning block from the orientation-based data. A parameter calculator calculates alteration parameters related to an actual orientation of the positioning block with respect to the bone as a function of the orientation reference and of the orientation of the positioning block.

    摘要： A calibration system for the calibration of a surgical instrument, comprises a surgical instrument having a working shaft. A clamp has a first trackable member and is releasably connected to the surgical instrument such that an orientation relation between the clamp and the working shaft of the instrument is known. A base is separated from the clamp and has a second trackable member and a positioning portion being tracked for position. A sensor unit tracks the first and second trackable members. A calibration unit calibrates the surgical instrument by initializing the orientation relation between the clamp and the working shaft from the tracking data to obtain an orientation of the working shaft, and by setting a position for the working shaft with respect to the first trackable member by relating the orientation of the working shaft to the position of the positioning portion when the working shaft contacts the positioning portion.
