Abstract
An active hearing aid implant is formed in an arrangement for the adjustment and fixation of the relative position between an axially extended actuator end piece of the hearing aid implant and the surrounding middle-ear bone. Arrangement coupling elements anchor the actuator end piece on the surrounding bone and a sliding ring designed to slide over the cylindrical actuator end piece holds this actuator end piece in a radial direction while the sliding ring remains linearly displaceable in the axial direction of the actuator end piece. Radially protruding coupling elements are fastened radially outwardly on the sliding ring for anchoring the sliding ring on surrounding bone after the arrangement has been surgically inserted into the middle ear.
