人工耳蜗也称为耳蜗植入(CochlearImplant)。本文综述了近几年来人工耳蜗研究的国外进展情况,重点介绍当前国外各研究组的人工耳蜗装置结构的特点,及其临床应用的一般情况。在正常的耳朵中,外界传来的声波引起鼓膜的振动,该振动通过中耳内的三个听小骨传至卵圆窗膜,并推动内耳耳蜗中的外淋巴液运动。根据传来的声音频率,外淋巴液在沿着耳蜗基底膜长度的特定部位,呈现出最大的运动。耳蜗中柯蒂氏器的感觉细胞(毛细胞)探测出液体的运动,并把它们转 Cochlear implants are also called Cochlear Implants. This review summarizes the progress of cochlear research abroad in recent years, and highlights the characteristics of cochlear implant structure and the general situation of its clinical application. In normal ears, sound waves from the outside cause vibrations of the tympanic membrane that pass through the three ossicles in the middle ear to the oval window membrane and promote perilymph movement in the cochlea of ​​the inner ear. Peripheral lymphatic fluid exhibits maximum motion at specific locations along the length of the basement membrane of the cochlea, according to the frequency of sound transmitted. The Cochlear sensing cells (hair cells) in the cochlea detect fluid movements and turn them around
