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 use in a stereotactic device is adapted for use in combination with a stereotactic bridge which includes a span rotatable on its horizontal axis and movably affixed to a C.T. scan table or an X-ray table by a positioning mechanism that provides for both vertical and horizontal movement of the span. The stereotactic device interacts with a C.T. scanner to achieve accurate placement of the selected medical device. Use of the stereotactic bridge allows alignment of the medical device in sagittal orientation with a high degree of accuracy.
