据日本的一个研究小组称,在今后三个月之内将装置世界上第一个永久性完全植入型助听器。最近在美国耳鼻喉科学系年会上,日本爱媛大学耳鼻喉科学系的直明柳原及其同事清藤行报告一篇论文。在会上,头颈部外科讨论了有关植入型助听器的最新进展。柳原借助Rion和Sanyo有限公司的帮助,在过去7年中一直从事完全植入型助听器系统的研究。研究小组发明的这种装置主要使用了生物形态的压电振动器。将一超微型电子传声器置于耳道皮下,通过一个植入式电池提供的附加能源,将声波变换为放大的电脉冲。放大的脉冲直接传入与镫骨接触的压电振动器,通过镫骨的直接振动, According to a Japanese research team, the world’s first permanent fully implantable hearing aid will be installed within the next three months. At the recent annual meeting of the Department of Otolaryngology, Ehime Naito and colleagues at Ehime University Department of Otorhinolaryngology, Ehime University, Japan, presented a paper. At the meeting, Head and Neck Surgery discussed recent advances in implantable hearing aids. With the help of Rion and Sanyo Co., Ltd., Liu Yuan has been engaged in the study of fully implantable hearing aid systems for the past seven years. The device invented by the research team mainly uses biomorphic piezoelectric vibrators. By placing an ultrastrong electronic microphone subcutaneously in the ear canal, the sound wave is converted into an amplified electrical pulse by the additional energy provided by an implanted battery. Amplification of the pulse directly into the tarsal contact with the piezoelectric vibrator, tarsal bone through the direct vibration,
