Method for calibration of the middle ear acoustic implant of a patient during tympanoplasty operations and the system for the application of this method

摘要

in the first patient individually for determined threshold audibility and known methods, a reference diagram audibility. subsequently, the hearing system, near the eardrum is hung up, and in the middle ear implant placed and electrode measurement, which is followed by verifying the acoustic signals.according to the method, at the same time, with the administration of checking the audio frames implant beam laser.subsequently, in the same time interval, the recorded signals of electro physiological assr, arising from reactions for given acoustic signals the implant, as well as the intensity and the characteristics of the reflected laser radiation "ldv - fft which is response of movable bones aids on the same complex acoustic signal.later, both types of signals obtained in a graphical and processing are compared in the course of surgery with the reference diagram audibility patient by adjusting or location of the implant.the system contains a block generation of acoustic signals (1) connected with an earpiece (2) and (3) through the electrode with the block register (4) and with a signal processing (5), and with the wizualizuju0105cym (6).in this system, the block (4) is additionally attached registration detector (7) radiation generated by a laser beam (8) and reflected from a mirror (9) placed on the repopulated implant, in the middle ear bones aids patient.
