I-depressor yolimi iyithuluzi lezokwelapha elilula kodwa elisetshenziswa kabanzi, elisetshenziselwa ikakhulukazi ukuhlolwa komlomo kanye ne-pharyngeal. Umsebenzi wawo oyinhloko uwukucindezela ulimi, okwenza odokotela babone ngokucacile izilonda ezindaweni ezifana namathoni, udonga lwangemuva lwepharyngeal, kanye ne-uvula. Idlala indima engenakubekezelelwa ekuxilongeni kokuqala kwezimo ezifana nezifo eziphezulu zokuphefumula, i-tonsillitis, ne-pharyngitis.
Ngokuphathelene nokuthuthukiswa kwezinto ezibonakalayo, abacindezeli bolimi baye bathola inguquko yezobuchwepheshe kusuka ezinkuni kuya ensimbi, bese kuba yipulasitiki yesimanje noma izinto ezilahlwayo. Izicindezeli zolimi zokhuni zendabuko zisetshenziswa isikhathi eside ngenxa yezindleko zazo eziphansi kanye nokukhululeka kokubulala amagciwane, kodwa zithwala ingozi{1}}yokutheleleka ngezifo ngokuphindaphindiwe. Ngemuva kwekhulu lama-20, izinciphisi zolimi zensimbi engagqwali zaba yinto evamile ezibhedlela ngenxa yokuqina kwazo kanye nokuziphendulela. Eminyakeni yamuva nje, izinciphisi zolimi zepulasitiki ezilahlwayo ezihlangabezana namazinga okuphepha kwe-biosafety ziye zanda kakhulu ngenxa yezidingo eziqinile zokulawula ukutheleleka, ikakhulukazi eminyangweni yezingane kanye nezifo ezithathelwanayo.
Emisebenzini yomtholampilo, abacindezela ulimi kufanele balandele izinqubo ezijwayelekile. Udokotela ngokuvamile ubamba isicindezeli solimi esandleni sakhe sokunene (isiguli sihlezi noma sibheke phezulu), ngokushesha nangokumnene ecindezela ingxenye engaphambili-yesithathu yolimi. Ngesikhathi esifanayo, kusetshenziswa ithoshi, ukuhlolwa kuqedwa ngokuchayeka kafushane kodwa okwanele. Le nqubo idinga ukunyakaza okuthambile ukuze kugwenywe ukuvusa i-nausea reflex, kuyilapho ubheka ngokucophelela imininingwane efana nombala we-mucosal, ukuvuvukala, nezici zokukhishwa.
Naphezu kwentuthuko eqhubekayo kubuchwepheshe be-imaging yezokwelapha, isicindezeli solimi sihlala siyithuluzi lokuhlola eliyisisekelo. Izindleko zayo eziphansi, ukushesha, kanye{1}}nokungahlaseleki kuyenza ibaluleke ngokukhethekile kuzilungiselelo{2}}ezinomkhawulo noma izilungiselelo zokunakekela izimo eziphuthumayo. Imfundo yesimanje yezokwelapha isahlanganisa ukusetshenziswa kokucindezela ulimi njengekhono eliyisisekelo, elibonisa ukubaluleka okuhlala njalo kwalesi sisetshenziswa esilula ekusebenzeni komtholampilo. Ngokuzayo, ngokusungulwa kwesayensi yezinto zokwakha, isicindezeli solimi singase sithuthukiswe ngokwengeziwe ngokuya nge-ergonomics nokuvikelwa kokutheleleka, kodwa umsebenzi wayo oyisisekelo njengebhuloho phakathi kukadokotela nesiguli uzohlala ungashintshile.
