Abstract
A guard device with angled cranium guide that can be removably and replaceably attached to an existing craniotome for producing a stable bone flap system includes an elongate stem defining a longitudinal axis between a proximal end and distal end. The proximal end is adapted for attachment to the craniotome. A footplate extends from the distal end of the stem at an angle with respect to the longitudinal axis of the stem. The footplate is positioned adjacent to the cutting portion of the craniotome and prevents the cutting portion from penetrating too far into the skull. On one side of the stem between the proximal and distal ends is an angled cranium guide. The dura guard with its angled cranium guide enables the surgeon to rest the guide agains the cranium and the maintain the craniotome at a fixed angle to cut a bone flap at an angle.
