Abstract

A device for adjusting and fixing relative position between an actuator end piece of an active hearing implant and an element of the ossicular chain or a coupling part to the human inner ear has a connecting element with a first coupling element for coupling to the actuator end piece, a second coupling element, and a shaft-shaped middle part, and the first coupling element geometrically encompasses the actuator end piece with two opposing parallel arms each having a pattern element to fix the encompassed actuator end piece in selectable discrete axial positions in a direction parallel to an axis of the shaft-shaped middle part, for variable-length adaptation and fixing of the actuator end piece relative to the first coupling element in a direction transverse to the axis.
