Method and device for installing an implant for a bone anchored hearing aid

摘要

A drill guide for installing an implant in a blind hole in a bone under a soft tissue is disclosed. The drill guide includes a cylindrical portion that includes a cylindrical canal extending along a longitudinal axis of the cylindrical portion. The cylindrical canal is adapted to receive a drill member for drilling the blind hole in the bone. The drill guide further includes a flange at a proximal end section of the drill guide. The drill guide extends perpendicular or substantially perpendicular to the longitudinal axis of the cylindrical portion. The drill guide has a length that is equal or greater than thickness of the soft tissue. A distal end of the drill guide, when inserted in a hole, is adapted to rest against a bone surface that interfaces with the soft tissue.
