    摘要: Arrangement for adjusting and fixing the relative position of two components of an active or passive hearing implant. A first one of the elements is rod-shaped at least in the fixing region. The other of the elements, at least in the fixing region, is sleeve-shaped and can be plastically cold-deformed by a crimping tool or is made as a belt loop which can be tightened and in the fixed state loops around the rod-shaped part over an angle of at least 360.degree.. The two elements are joined permanently to one another without play by cold-flow deformation of the sleeve-shaped part or by force-fit and/or form fit when the belt loop is tightened.

    摘要: A permanently implantable, fixable positioning system (1) for stationary attachment to a human body, without play, preferably to the human skull. It has ball-and-socket joint (3), linear axle (4) fixed stationary to it, and a carriage (5) which is guided on the linear axle for accommodating an implantable actuator or sensor device (6). The combination of the axial degree of freedom of the linear axle (4) with three degrees of rotational freedom of the ball-and-socket joint (3) allows a surgeon four-axis, in-situ positioning of the implantable means especially in the middle ear and mastoid cavities. By using the positioning system, precise positioning of a free active end (16) of the implantable device (6) relative to sensitive anatomical structures of the human body is enabled while avoiding risky relative movements between the implantable device and the body of the patient. The positioning system is thus used more or less as a "tremor-free artificial hand" of the surgeon. According to one preferred embodiment, the implantable device is an implantable piezoelectric hearing aid transducer of a partially or completely implantable hearing aid.

    摘要: Temporarily fixable positioning system (1) for secure, play-free fastening to the human body, preferably to the human skull has a base (4), a clampable ball-and-socket joint (3), a linear axis mechanism (2) fixed securely to it and a carriage (6) guided along the linear axis mechanism for receiving an actuator or sensor instrument (12). For intraoperative use, the positioning system is combined with a retractor (27). A head support (31) is provided for noninvasive diagnostic or therapeutic applications. The combination of the axial degree of freedom of linear axis (2) with the three rotational degrees of freedom of the ball-and-socket joint (3) allows four-axis, in situ positioning of the instrument on or in the skull, especially in the external auditory canal and an opened middle ear. The positioning system in combination with one of the holders enables precise positioning of an active end (14) of a guided instrument (12) relative to sensitive anatomical structures while avoiding risky relative movements.
