Vocal chords prosthesis and method of tuning such vocal chords prosthesis

摘要

The invention relates to an artificial vocal cords (1) which has two parts and its parts are laterally slidably mounted in opposite walls of the guide frame (5) and in the longitudinal direction are attached on one side to a mounting wall (9) of the guide frame (5) and on the opposite side to the fastening wall (9) stavícího frame (6), the inner space (4) artificial vocal chords (1) is connected to a pressurized fluid source. Furthermore, the present invention relates to the method of tuning the pitch-substitutes, which comprises, by determining the fundamental frequency of vocal cords humans on the basis of which will set the preload artificial vocal chords by adjusting the distance of the guide frame (5) and stopping frames (6) encompassing the artificial vocal chords and subsequently varies the vibration characteristics of artificial vocal chords changing the fluid pressure in the artificial vocal cord, which are monitored and compared with the desired vibrational characteristics for human glottis to obtain the similarity between the vibration characteristics of artificial and human vocal chords.
