ADJUSTABLE NAVIGATED SURGICAL DRILL SHEATH

Abstract

An adjustable navigated surgical drill sheath includes a handle, main body, and adjustment arrangement. The main body can receive a separate surgical drill bit through a top opening, a hollow region therethrough, and a bottom opening. The adjustment arrangement can facilitate setting a specific drill depth corresponding to the maximum distance that the drill bit can extend past the bottom opening and allows for multiple different specific drill depths. The adjustment arrangement can include a removable insert having locking features than can be moved up and down within the hollow region and a latching mechanism that interacts with the locking features to lock the insert at a specific position relative to the main body to set the specific drill depth. Fiducial markers coupled to the main body can facilitate use of the surgical drill sheath as a navigated device in an augmented reality environment.
