Abstract
A stereotactic guide apparatus is disclosed for positioning a surgical instrument along three axes. The disclosed stereotactic guide apparatus is adapted for use in neurosurgical procedures in conjunction with a conventional headframe mounted to a patient's skull and having an arc extending above and across the skull. A platform is mounted to the arc of the headframe. An X-slide is mounted to the platform for movement along the X-axis. A Y-slide is mounted to the X-slide for movement along the Y-axis. A Z-stage is mounted to the Y-slide. By moving the X-slide and Y-slide, the Z-stage is thus positionable along both the X- and Y-axes. The Z-stage includes an instrument slide mounted for movement along the Z-axis. A surgical instrument such as an electrode, injection cannula, or biopsy needle can be mounted to the instrument slide for movement of the instrument along the Z-axis.
