Abstract

A stereotactic device of simplified structure, adaptable to align and precisely orient a variety of medical devices such as differently sized needles, cannulas and guide wires into the human body for procedures such as tumor biopsies, percutaneous discectomies, cyst aspirations and tumor localizations is described. The device described is adapted for use in combination with a stereotactic bridge comprised of a span rotatable on its horizontal axis and movably affixed to a C.T. scan table or X-ray table by positioning means providing vertical and horizontal movement of the span. The described device is interactive with a C.T. scanner to achieve accurate placement of the oriented medical device. Use of the stereotactic bridge allows alignment of medical devices in sagittal orientation with a high degree of accuracy.
