A awlsam zawngin ABI chu eng nge ni?

ABI hi Auditory Brainstem Implant tih tawifelna a ni. Sinhala tawng chuan Auditory Brainstem Implant tihna a ni. Hei hi hriatna hloh thuk ber, chu chu beng chhungril lama ri mantu (cochlea emaw beng hnah) emaw, chu aw signal te thluaka phurtu nerve (the auditory nerve) emaw chuan sound , emaw, pian tirh atanga awm lo emaw, hriat theihna atana hmanraw bik a ni.

I beng atanga i thluak thlenga aw phurtu nerve chu kawngpui angin ngaihtuah rawh. He bridge hi a chhiat chuan sound hian a cross thei lo va, thluak a thleng thei lo. Chutah chuan ABI device chu a rawn lut a, a bridge (nerve) chhe tawh chu a bypass a, thluak chhunga hriatna control tu (brainstem) lamah signal a thawn nghal a ni. Hei hi hriatna pangngai angin a ri lo a, mahse aw khawvel nena inzawmna siam leh theihna hun tha tak a pe che a ni.

He device hi eng ang nge a nih? Pang hnih a nei em?

Ni e, he device hian part lian pahnih a nei a. Pakhat chu taksa pawnah bun a ni a, pakhat zawk chu surgery hmanga taksa chhungah dah a ni.
