Kumashumi ambalwa eminyaka adlulileyo, uyilo lokufakelwa kunye noPhando lobuNjineli bofakelo lwamazinyo lwenze inkqubela phambili enkulu. Olu phuhliso lwenze izinga lempumelelo yokufakelwa kwamazinyo ngaphezu kwe-95% iminyaka engaphezu kwe-10. Ke ngoko, ukufakelwa kokufakelwa kuye kwaba yindlela enempumelelo kakhulu yokulungisa ukulahleka kwamazinyo. Ngophuhliso olubanzi lokufakelwa kwamazinyo kwihlabathi, abantu bahlawula ingqalelo ngakumbi nangakumbi ekuphuculweni kokufakelwa kunye neendlela zokulondoloza. Okwangoku, kubonakalisiwe ukuba i-laser inokudlala indima esebenzayo kukufakelwa kokufakelwa, ukufakwa kweprosthesis kunye nolawulo losulelo lwezicubu ezijikeleze ukufakelwa. I-laser ye-wavelength eyahlukeneyo ineempawu ezizodwa, ezinokunceda oogqirha baphucule umphumo wokufakelwa kwonyango kunye nokuphucula amava ezigulana.
I-Diode laser incedise unyango lokufakela lunokunciphisa ukopha kwi-intraoperative, inike indawo yotyando elungileyo, kwaye inciphise ubude botyando. Kwangaxeshanye, i-laser inokudala indawo eyinyumba elungileyo ngexesha nangemva kokusebenza, ukunciphisa kakhulu izehlo zeengxaki zasemva kokuhlinzwa kunye nosulelo.
Ubude obuqhelekileyo belaser ye-diode bubandakanya i-810nm, 940nm,980nmkunye ne-1064nm. Amandla ezi lasers ajolise ikakhulu kwi-pigments, njenge-hemoglobin kunye ne-melanin ngaphakathiizihlunu ezithambileyo. Amandla e-diode laser ahanjiswa ikakhulu ngefiber optical kwaye asebenza kwimodi yokunxibelelana. Ngexesha lokusebenza kwe-laser, iqondo lobushushu le-fiber tip linokufikelela kwi-500 ℃ ~ 800 ℃. Ukushisa kunokugqithiselwa ngokufanelekileyo kwizicubu kwaye kunqunywe ngokufaka umphunga kwizicubu. I-tissue idibene ngokuthe ngqo kunye nobushushu obuvelisa i-tip yokusebenza, kwaye umphumo we-vaporization uyenzeka endaweni yokusebenzisa iimpawu ze-optical laser ngokwayo. I-laser ye-wavelength diode ye-980 nm ine-laser ephezulu yokufunxa emanzini kune-810 nm wavelength laser. Eli nqaku lenza i-980nm diode laser ikhuseleke ngakumbi kwaye isebenze kwizicelo zokutyala. Ukufunxwa kwamaza okukhanya yeyona nto inqwenelekayo isiphumo sokusebenzisana kwezicubu ze-laser; Okona kulungileyo amandla afunxwa sisicwili, kokukhona ukuncipha komonakalo wobushushu ojikelezileyo obangelwa kukufakelwa. Uphando lukaRomanos lubonisa ukuba i-980nm diode laser ingasetyenziswa ngokukhuselekileyo kufutshane nomphezulu wofakelo nakwisetingi yamandla ephezulu. Uphononongo luqinisekisile ukuba i-810nm diode laser inokonyusa kakhulu ubushushu bomphezulu wokufakelwa. I-Romanos iphinde yaxela ukuba i-810nm laser inokonakalisa ubume bomgangatho wokufakelwa. I-940nm diode laser ayizange isetyenziswe kunyango lokufakelwa. Ngokusekelwe kwiinjongo ezixoxwe kwesi sahluko, i-980nm diode laser kuphela kwe-laser ye-diode enokuthi ithathelwe ingqalelo kwisicelo kunyango lokufakelwa.
Ngelizwi, i-980nm diode laser ingasetyenziswa ngokukhuselekileyo kunyango oluthile lokufakelwa, kodwa ubunzulu bayo bokusika, isantya sokusika kunye nokusebenza kakuhle kulinganiselwe. Inzuzo ephambili ye-laser diode yincinci encinci kunye nexabiso eliphantsi kunye neendleko.
