    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 system tracks an object in computer-assisted surgery. The system comprises a sensor unit secured to the femur. Gyroscopes on the sensor unit produce readings related to orientation data about three axes of rotation. A tracking unit receives the gyroscope readings. An axis calibrator on the tracking unit comprises a calculator for adding at least part of the gyroscope readings for specific movements of the object about a desired axis. An axis normalizer on the tracking unit determines an orientation of the desired axis with respect to the sensor unit from the added gyroscope readings. A tracking processor tracks the desired axis from the gyroscope readings. An interface displays orientation data for the object from a tracking of the desired axis. A method for tracking an object with a gyroscope sensor unit is also provided.

    摘要： A system and method for repairing an area of defective tissue reduces the removal of healthy tissue at the margins of the defect. During excision of diseased or damaged tissue, the system tracks the movement and function of a tissue resection tool within a monitored surgical space. This movement is continuously recorded to create a three-dimensional set of data points representative of the excised volume of tissue. This data set is then communicated to a custom implant forming device which creates a custom implant sized to fit the void created by the excision. The system and method of the present disclosure allows a surgeon to exercise intraoperative control over the specific shape, volume and geometry of the excised area. Moreover, the surgeon may utilize a “freehand” resection method to excise only that tissue deemed to be diseased and/or damaged, because the custom-formed implant will accommodate an irregularly-shaped resection volume.

    摘要： An optical tracking system includes at least one tracking array for generating and optically transmitting data between 1 and 2,000 MB/s. At least one tracker for optically receiving the optically transmitted data between 1 and 2,000 MB/s is also provided. The tracking system is used not only for tracking objects and sending tracking information quickly but also providing the user or other components in an operating room with additional data relevant to an external device such as a computer assisted device. Orthopedic surgical procedures such as total knee arthroplasty (TKA) are performed more efficiently and with better result with the optical tracking system.

The bracket body sometimes having an aperture therein for knob attachment. A fiducial attachment member extends away from the bracket body, where a distal end of the fiducial attachment member is an attachment point for the one or more fiducials. A method of using the fiducial attachment device is also provided. A system for using a fiducial attachment device of during a surgical procedure is also provided.
