This invention is an apparatus, and method for guiding a surgical instrument within, and around the human body. During surgery on the body it is often necessary to approach a specific anatomical location precisely directly in order to minimize unwanted surgical trauma, and to place a soft tissue incision or a bone drill hole in an accurate location. The invention employs a light emitter (16), an array of light sensors (21-24), and a display (12) to accurately locate an anatomical feature into which the light emitter (16) has been placed. The light emitted from the emitter (16) is detected after passing through a thickness of bone, and/or soft tissue by the sensor array (21-24). The signal from the sensor array (21-24) is processed, and information indicating the relative direction of the emitter (16) from the sensor (21-24) is displayed. The surgeon then can proceed in the direction indicated. |
