  • Patent number: 8768437
    Abstract: A system and apparatus allows the tracking of a selected body portion, instrument, or both. A tracking device can be interconnected to a body portion at a mounting site. A procedure can be performed at a location remote from the mounting site of the tracking device. The tracking device can be interconnected with the body in a low invasive manner.

  • Patent number: 7130676
    Abstract: A fluoroscopic image guided surgery system, comprising a C-arm fluoroscope for obtaining fluoroscopic images of an object bone, the C-arm fluoroscope including at least one set of emitters; a reference bar capable of attaching to an object bone, the reference bar including emitters; a surgical instrument for performing an operation, the instrument including emitters; a digitizer system in communication with the at least one set of emitters of the C-arm fluoroscope, the emitters of the reference bar, and the emitters of the surgical instrument so that the digitizer system can determine a position of each of the C-arm fluoroscope, the reference bar, and the surgical instrument; and a single fiducial marker for attachment to an object bone, the single fiducial marker being visible in the fluoroscopic images for determining a position of an object bone relative to the digitizer system.

  • Patent number: 5772594
    Abstract: The present invention is an improved system for allowing an orthopaedic surgeon to safely determine the precise trajectory of insertion of a guide pin or screw into an object bone and to check the accuracy of the procedure using real time feedback. The system uses a C-arm fluoroscope in conjunction with a three-dimensional optical digitizer to provide a real time image of the drill and object bone on a screen. The system uses light emitting diodes (LEDs) positioned on the C-arm fluoroscope and on the drill and two dimensional image registration of the object bone to orientate the surgeon. In addition, LEDs are attached to a reference bar positioned on the object bone. The distinctive pattern formed by the combination of these elements allows the surgeon to continually observe the progress of the surgery without necessitating additional x-ray images.
