Abstract

An apparatus for positioning instrumentation into a target region of a brain generally includes an attachment member, specifically a disc adapted to be secured to a cranium, and a marker assembly adapted to be connected to a locator device, for example a conventional stereotaxic assembly. The marker assembly includes a detachable cannula, and is further adapted to be secured to the attachment member in order to immobilize the cannula at a precise position in the brain, thus facilitating additional imaging of the patient in order to determine the position of the cannula with respect to the target region.
