1. A method for tracking the three-dimensional position of a surgical instrument while the instrument is being utilized within a patient body during a surgery, comprising the steps of:

  • capturing a stereoscopic image of an exterior of the patient body during the surgery;

    wirelessly determining the three-dimensional position of the patient body relative to a first reference point;

    wirelessly determining the three-dimensional position of the surgical instrument relative to the first reference point;

    calculating the three-dimensional position of the surgical instrument relative to the patient body; and

    superimposing a graphical representation of the surgical instrument and its three-dimensional position upon the captured stereoscopic image of the patient body.
