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 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. The stereotactic device is organized so as to allow a user to introduce accurately the medical device through a sterile field into the human body at a preselected angle. The stereotactic device includes a base, a leg normal to the base, a carrier for the medical device, and markings on the leg. The carrier for the medical device also has a radial portion, a retainer for the medical device, and a lock for fixing the medical device at a selected position.
