人工耳蜗是一种能替代人耳功能的特殊的声-电转换电子装置,其工作原理是将环境中的机械声信号转换为电信号,并将该电信号通过电极传入患者耳蜗,刺激患耳残存的听神经而使患者产生听觉。至今,人工耳蜗植入已成为帮助重度及极重度耳聋患者重获听力或全聋儿童恢复言语能力的一个有价值的方法。 Cochlear implant is a kind of special acousto-electric conversion electronic device that can replace the function of the human ear. Its working principle is to convert the mechanical sound signal in the environment into electrical signal and transmit the electrical signal to the patient’s cochlea through the electrode to stimulate the patient Ear residual auditory nerve and the patient to produce hearing. To date, cochlear implants have become a valuable way to help regain speech among hearing-impaired or deaf children in severely and severely deaf patients.
