    • A fixation element secures to a patient's ear an implantable microphone having a cylindrical housing part with an acoustic inlet membrane after insertion into a hole which crosses a rear bony wall of the patient's auditory canal. The fixation element has a cylindrical sleeve part which surrounds the cylindrical housing part of the microphone and which has projecting, elastic flange parts which can be placed against the side of the wall of the auditory canal which faces the skin of the auditory canal. In use, the elastic flange parts are held in a bent position against an elastic restoring force of the flange parts, before implantation, by applying a holder to the flange parts which allows insertion of the flanges through the hole of the wall of the auditory canal. After the microphone assembly has been inserted through the hole, the holder (which can be, for example, thread or a cap) is removed allowing the elastic flange parts to spring into a position in which they project essentially radially away from the cylindrical sleeve part between the wall of the auditory canal which faces skin of the auditory canal and the skin of the auditory canal.
    • 固定元件将可植入麦克风固定到患者的耳朵上,所述可植入麦克风具有圆柱形的外壳部分,其在插入穿过患者耳道的后骨壁的孔中之后具有声学入口膜。 固定元件具有围绕麦克风的圆柱形壳体部分的圆柱形套筒部分,并且具有突出的弹性凸缘部分,弹性凸缘部分可抵靠面向耳道皮肤的耳道壁的一侧放置。 在使用中,弹性凸缘部分在植入之前通过将凸缘部分施加到凸缘部分上来抵抗凸缘部分的弹性恢复力而保持在弯曲位置,该凸缘部件允许凸缘穿过耳道壁的孔 。 在麦克风组件已经穿过孔插入之后,保持器(其可以是例如螺纹或盖)被移除,允许弹性凸缘部件弹簧进入基本上径向远离圆柱形套筒部件的位置 在面向耳道皮肤的耳道的耳道与耳道的皮肤之间。
