| 摘要 |
The invention relates to an implantable actuator for direct stimulation of a patient's cochlea comprising a frame (76) to be fluid-tightly fixed within the patient's oval window in a manner to replace the stapes footplate (81) and having an oval shape conforming to the shape of the oval window, a rigid vibration element (78) for acting on the perilymph fluid, which vibration element is guided within the frame (76), an elastic holding element (80) fixed both at the frame (76) and at the vibration element (78) and extending laterally between the frame (76) and the vibration element (78) for allowing axial movement of the vibration element relative to the frame but preventing lateral movement of the vibration element relative to the frame, and a rod (74) having a first end to be driven by the tympanic membrane, an ossicle or a driver (70) of an at least partially implantable hearing aid and a second end connected to the vibration element (78) for causing reciprocating movement of the vibration element (78) within the frame (76). |
