ABSTRACT:
A method and an instrument are presented for reliably, accurately and easily locating intracranial targets and guiding surgical instruments to intracranial targets in human patients. An adjustment apparatus and a portable guider 70 constitute main components of the invention. The method and instrument make use of images of natural reference points or fiducial markers found in CT/MRI images of patient's head. In accordance with the present method, after the adjustment apparatus is mechanically adjusted based on the information gathered from CT/MRI images, the adjustments are transferred by a special procedure to the portable guider. The portable guider is the only component employed during surgery, resulting in minimal general intrusion with the work of the surgeon.
