Ib Nd: YAG laser yog lub xeev ruaj khov laser muaj peev xwm tsim tau qhov ze-infrared wavelength uas nkag mus tob rau hauv daim tawv nqaij thiab nkag tau yooj yim los ntawm hemoglobin thiab melanin chromophores.Lub lasing nruab nrab ntawm Nd: YAG (Neodymium-doped Yttrium Aluminium Garnet) yog ib tug txiv neej ua siv lead ua (khoom nyob rau hauv lub xeev) uas yog pumped los ntawm ib tug siab siv lub teeb thiab muab tso rau hauv ib tug resonator (ib kab noj hniav muaj peev xwm amplifying lub zog ntawm lub laser) .Los ntawm kev tsim lub sijhawm ntev ntawm cov mem tes sib txawv thiab qhov chaw tsim nyog, nws muaj peev xwm ua kom sov cov ntaub so ntswg sib sib zog nqus, xws li cov hlab ntsha loj thiab cov hlab ntsha.
Lub Ntev Pulsed Nd: YAG laser, nrog rau qhov zoo tshaj plaws wavelength thiab mem tes ntev yog ib qho kev sib xyaw ua ke rau kev txo cov plaub hau tas mus li thiab kho cov hlab ntsha.Lub sijhawm ntev pulse kuj tseem ua rau muaj kev txhawb nqa ntawm collagen rau lub ntsej muag nruj thiab firmer saib.
Cov teeb meem ntawm daim tawv nqaij zoo li Port Wine Stain, Onychomychosis, Pob txuv thiab lwm yam tuaj yeem txhim kho tau zoo los ntawm Long Pulsed Nd:YAG laser ib yam nkaus.Qhov no yog lub laser uas nthuav tawm kev kho ntau yam, txhim kho kev ua tau zoo thiab kev nyab xeeb rau cov neeg mob thiab cov neeg ua haujlwm.
Ntev Pulsed Nd: YAG Laser Ua Haujlwm Li Cas?
Nd: YAG laser zog yog xaiv absorbed los ntawm qhov tob ntawm cov dermis thiab tso cai rau kev kho mob ntawm cov hlab ntsha ntxaum xws li telangiectasias, hemangiomas thiab ceg leeg.Lub zog laser yog xa los siv cov pulses ntev uas hloov mus rau hauv cov ntaub so ntswg.Lub tshav kub cuam tshuam rau vasculature ntawm qhov txhab.Tsis tas li ntawd, Nd:YAG Laser tuaj yeem kho nyob rau theem siab dua;los ntawm cua sov ntawm daim tawv nqaij subcutaneous (nyob rau hauv ib tug tsis-ablative yam) nws nkoos neocollagenesis uas txhim kho cov tsos ntawm lub ntsej muag wrinkles.
Nd:YAG laser siv rau kev tshem tawm cov plaub hau:
Histological cov ntaub so ntswg hloov mirrored soj ntsuam teb cov nqi, nrog pov thawj ntawm xaiv follicular raug mob yam tsis muaj kev cuam tshuam epidermal.Kev xaus Lub sijhawm ntev-pulsed 1064-nm Nd: YAG laser yog txoj kev nyab xeeb thiab siv tau zoo ntawm kev txo cov plaub hau ntev rau cov neeg mob uas muaj cov tawv nqaij tsaus.
Puas yog YAG laser zoo rau kev tshem tawm cov plaub hau?
Lub Nd:YAG laser tshuab yog qhov zoo tshaj plaws rau: Nd:YAG system yog cov plaub hau tshem tawm laser xaiv rau cov tib neeg uas muaj tawv tawv tones.Nws yog qhov loj wavelength thiab muaj peev xwm los kho cov cheeb tsam loj ua rau nws zoo tagnrho rau kev tshem cov ceg plaub hau thiab cov plaub hau rov qab.
Nd:YAG muaj pes tsawg zaus?
Feem ntau, cov neeg mob muaj 2 mus rau 6 qhov kev kho mob, kwv yees li txhua 4 mus rau 6 lub lis piam.Cov neeg mob uas muaj hom tawv nqaij tawv yuav xav tau kev kho mob ntau dua.
