IMPLANTABLE MIDDLE EAR HEARING DEVICE WITH TUBE TYPE VIBRATION TRANSDUCER

摘要

An implantable middle ear hearing device using a tube type vibration transducer is provided to reduce a temporal bone incision work greatly by inputting sound into round window side using a tube type vibrator for minimizing volume of a signal and attenuation of a high frequency band. An implantable middle ear hearing device using a tube type vibration transducer includes: a microphone(200); a signal processing part(300); a hollow tube member one side of which is connected to the signal processing part, and the other side is inserted into an entrance of round window(B); a vibration generating unit(120) installed in the tube member, and generating a mechanical vibration signal or a sound signal by receiving an electric signal by the signal process part; and a signal wire member(130) installed in the tube member, connected to the signal processing part and the vibration generating unit, and transferring the electric signal by the signal process part to the vibration generating unit.
