    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: A surgical instrument having a grip, a reference structure and an alignment head and method of using. The reference structure has at least one reference element that is registrable in a computer assisted navigation system. The reference element may be a reflective structure for use in an optical tracking system, wire loop for sensing a magnetic field, or other suitable device. The alignment head has a substantially planar alignment surface and may also have a plurality of outwardly extending projections or an electrocautery electrode disposed along an edge of the alignment surface and extending parallel to the alignment surface. The projections may be engaged with an anatomical structure to hold the alignment head in a desired position as the alignment surface is used as a guide to mark the anatomical structure. The disclosed instrument may be used when resecting a femur to prepare the femur to receive the femoral component of a prosthetic hip joint.

    摘要: A detachable support arm structure couples a computer-assisted navigation system reference array to an instrument, for example, a surgical instrument, such that the geometry between the reference array and the surgical instrument is predetermined and registration of the instrument in the navigation system does not require calibration each time the reference array and support arm structure are coupled to the instrument. The support arm structure includes a mounting interface engageable with a mounting interface on the instrument. Engagement of the mounting interfaces releasably secures and repeatably and accurately locates and fixes the support structure to the instrument in a predefined geometry in each of six degrees of freedom. The reference array includes at least one reference element and is releasably securable to the support structure in a predefined geometry of the support structure relative to the reference array which repeatably and accurately locates and fixes the support structure relative to the reference array in each of six degrees of freedom.

    摘要: Instruments for use in resecting, reshaping, and preparing the end of a bone to receive an implant. The instruments may be equipped with indicator devices in the form of light-emitting devices to project an indicator onto the bone. Examples of such instruments may be a cut guide equipped with a built-in cut plane indicator device and a cut plane indicator device for use with existing cut guides. The cut plane indicator device may provide a visual indication or cue on a surface of the bone indicating where the cut plane of the cut guide will intersect the bone.
