摘要

Implantable sensor-actuator converter module for hearing rehabilitation in the middle ear according to DE 10 2009 051 057 B4, consisting of a sensor for recording vibrations from the ossicular chain and converting it into an electrical signal and an actuator for converting electrical signals into mechanical vibrations and initiating the mechanical vibrations in the ossicular chain, at least part of the sensor (11) being mechanically connected to at least part of the actuator (12), the sensor (11) for amplifying the electrical signal with an electronic processing unit (10) and for controlling the actuator (12) the electronic processing unit (10) has an electrical connection (9) with the actuator, and means are provided for decoupling the mechanical feedback effects of the actuator (12) on the sensor (11) which have a function of the actuator (12) produce the opposite effect on the sensor (11) and thereby the effect of the actuator (12 ) on the sensor (11), characterized in that a cylindrical body (11b) is provided, an open side of the cylindrical body is covered with an oscillatable membrane that is connected to a sensor element (11a), the opposite side of the cylindrical body is connected to a second housing part in the form of a cylindrical body (12b), the open side of the second cylindrical body being covered by a further oscillatable membrane which is connected to an actuator element (12a) and an active element ( 13) is arranged.
