ABSTRACT:
This invention relates to a drill guide particularly useful for drilling an accurately located and oriented bore of limited depth into an orbital implant for purposes of fixating an orbital prosthesis. The drill guide comprises a cylindrical housing, the distal end of the housing defines a plurality of fixation pegs which are engagable with the orbital implant. An adaptor insert is placed on the nonrotating nose of a surgical drill which defines an outer diameter which is closely received by the drill guide housing. Features are provided to limit the depth of insertion of the adaptor insert. After placement of the drill guide on the orbital implant the surgical drill can be advanced until the physical stop is reached providing a limited depth bore which can be accurately located and oriented.
