    摘要： A universal tracking apparatus for a surgical instrument, the tracking apparatus including a support arm and tracking array. The support arm allows position adjustment of the tracking array between a number of predefined orientations relative to the instrument which are recognizeable and registerable in the navigation system. The support arm may be coupled with multiple types of surgical instruments and used to accurately define the position of the instrument in an anatomical model generated by the navigation system. The adjustable coupling between the tracking array and the support arm allows the surgeon to determine which orientation is best suited for the surgical application and also allows the surgeon to adjust the position of the tracking array during a surgical procedure without the need to re-register the tracking apparatus. The tracking array may also include at least one repositionable reference element to allow a single tracking array to be configured for use with a plurality of different instruments, wherein differing geometries defined by the tracking array and corresponding to particular instruments are recognizable and registerable by the navigation system.

    摘要： A system for registering an orthopedic implant in a computer assisted navigation system. The system includes a plurality of differently sized implants which may be the femoral component or hip stem of a prosthetic hip joint. A registration device is engageable with each of the implants in a predefined relative position. The registration device also includes at least one reference element registerable in the computer assisted navigation system. A second reference structure also having at least one reference element registerable in the computer assisted navigation system is detachably secured to the implant. The relative positions of the reference elements located on the registration device and second reference structure differs for each of the plurality of implants and thereby allows the navigation system to determine the nominal size of the implant. The relative position and orientation of the implant relative to the second structure can also be calibrated using the registration device.

    摘要： The present invention relates to a bone-cutting guide intended to be temporarily positioned against a resected bone surface at a bone-cutting surface. The bone-cutting guide is also positioned at at least one secondary bone surface, and configured to receive a cutting member to cut the bone at the bone-cutting surface. The bone-cutting guide includes a tower and a paddle extending from the tower. The paddle is configured to be positioned at the bone-cutting surface, and has a cutting tool receiving portion configured and arranged to receive the cutting member to cut the bone at the bone-cutting surface. The bone-cutting guide also includes a base extending from the tower and configured to be positioned on the resected bone surface. The base has at least one bone-engaging surface configured and arranged to be positioned at the at least one secondary bone surface. An angle adjuster is provided for adjusting the angle between the tower and the base in the plane of the resected bone surface.

    摘要： An apparatus for indicating a plurality of anatomical landmark locations includes a tracking device and a guide member extending from the tracking device. The guide member is configured to space the tracking device away from a first and a second one of the plurality of anatomical landmark locations, and concurrently pivotally position the tracking device based at least in part on a third one of the plurality of anatomical landmark locations. A method for facilitating acquisitions of locations of anatomical landmarks by a computer-assisted knee arthroplasty system includes concurrently abutting a guide member against at least three of the landmarks, and indicating a location of the guide member to the system concurrently with abutting the guide member against the at least three of the landmarks.
