Abstract
Described herein is a cranial surgery drill bit having a safety self stopping mechanism for use on bone material to prevent or repair skin erosion and infection which may result from the placement of a cap for holding the lead from Deep Brain Stimulation surgery. The surgical procedure of attaching a lead holding cap onto the bone material of a skull requires an attachment which results in no movement of the lead. Accordingly, counter boring the skull surrounding a pre-existing perforation bore so that the cap is not significantly above the surface of the skull is a technique which allows the cap user to brush hair, etc., without disrupting the attachment and placement of the lead.
