Laser thev naus laus zis tau hloov kho kev tu tawv nqaij niaj hnub, nrog pico laser chaw tshem tawm sawv tawm raws li kev daws teeb meem rau kev daws teeb meem pigmentation. Txawm li cas los xij, qhov siab -lub zog ntawm lasers yuav tsum muaj cov txheej txheem kev nyab xeeb nruj heev los tiv thaiv ob tus kws tshaj lij thiab cov neeg mob. Kab lus no tshawb txog kev tshawb fawb tom qab pico laser kev kho mob, cov wavelengths uas siv rau kev tshem tawm qhov muag, qhov muag phom sij thaum ua haujlwm, thiab cov lus qhia tseem ceeb rau kev xaivlaser kev ruaj ntseg khoom.
Pico Laser Spot Tshem Tawm Ua Haujlwm Li Cas
Pico laser ua haujlwm ntawm lub hauv paus ntsiab lus ntawmultra- lub sijhawm luv luv( ntsuas nyob rau hauv picoseconds, los yog 10⁻¹² vib nas this), uas muab siab - siv zog rau lub hom phiaj pigment hlwb nrog tsawg thermal puas. Nov yog nws ua haujlwm li cas:
Photoacoustic nyhuv: Lub laser generates siab nthwv dej uas shatter pigment hais rau hauv nanoscale fragments, ua rau lawv yooj yim rau lub cev tshem tawm.
Xaiv Lub Hom Phiaj: Lub zog yog absorbed tshwj xeeb los ntawm melanin (cov xim ua lub luag haujlwm rau cov pob), sparing ib puag ncig cov ntaub so ntswg noj qab haus huv.
Collagen Stimulation: Tom qab-kev kho mob, lub laser kuj txhawb collagen regeneration, txhim kho daim tawv nqaij zoo nkauj thiab txo cov kab zoo.
Piv nrog rau cov tsoos nanosecond lasers, pico lasers txo cov cua kub tsub kom txog li 90%, ua rau lub sij hawm rov qab sai dua thiab muaj kev phiv tsawg.
Common Wavelengths rau Pigmentation Treatment
Qhov sib txawv wavelengths nkag mus rau ntawm daim tawv nqaij ntawm qhov sib txawv qhov tob, ua rau lawv haum rau cov xim pigmentation tshwj xeeb:
1064nm (Nyob ze -Infrared): Zoo tagnrho rau kev sib sib zog nqus pigmentation (piv txwv li, melasma, freckles) vim nws qhov tob tob tob.
755nm (Alexandrite Laser): Siv tau rau sab nraud mus rau nruab nrab - txheej pigmentation (piv txwv li, tshav ntuj, hnub nyoog me me).
532nm (Lub teeb ntsuab): Targets nto-theem pigmentation (piv txwv li, pob txuv liab caws pliav) thiab vascular txhab.
694nm (Ruby Laser): Feem ntau siv rau epidermal pigmentation tab sis yuav xav tau lub sij hawm rov qab ntev dua.
Xaiv qhov zoo wavelength ua kom pom cov txiaj ntsig zoo thaum txo qis kev pheej hmoo.
Qhov muag phom sij thaum ua haujlwm Laser
Txawm tias muaj kev nyab xeeb zoo tshaj plaws, lasers ua rau muaj kev pheej hmoo loj rau lub qhov muag yog tias tsis ua raws li kev ceev faj. Cov phom sij tseem ceeb muaj xws li:
Retinal Burns:
Pom tau thiab nyob ze -infrared wavelengths (piv txwv li, 532nm, 1064nm) tuaj yeem dhau los ntawm lub cornea thiab lens, tsom lub zog ntawm retina. Ib qho kev tshwm sim tuaj yeem ua rau tsis muaj kev puas tsuaj.
Pico lasers amplify qhov kev pheej hmoo no vim lawv ultra- pulses luv thiab siab ncov lub zog.
Corneal puas:
Ultraviolet (UV) lasers (qis dua 400nm) yog absorbed los ntawm lub cornea, uas yuav ua rau keratitis los yog mus tas li opacity.
Scattered Light Exposure:
Kev xav los ntawm cov khoom siv hlau, cov cuab yeej phais, lossis tus neeg mob daim tawv nqaij tuaj yeem tsim txoj hauv kev tsis pom kev, ua rau muaj kev pheej hmoo raug mob.
Xaiv cov khoom siv Laser Safety
Cov iav tiv thaiv zoo yog qhov tseem ceeb rau kev tiv thaiv kev raug mob. Nov yog yuav ua li cas xaiv cov cuab yeej zoo:
Wavelength Compatibility: Xyuas kom cov tsom iav raug ntsuas rau cov laser wavelengths tshwj xeeb siv (xws li 1064nm, 532nm).
Optical Density (OD): Rau pico lasers, tsom iav nrog OD Ntau dua lossis sib npaug ntawm 4.0 raug pom zoo los thaiv 99.99% ntawm cov hluav taws xob tsis zoo. Cov txiaj ntsig OD siab dua (Ntau dua lossis sib npaug rau 7.0) yog qhov zoo tagnrho rau siab - lub zog hluav taws xob.
Cov ntawv pov thawj: Nrhiav kev ua raws li cov qauv thoob ntiaj teb xws liANSI Z136.1los yogEN 207/208.
Kev nplij siab thiab haum: Xaiv lub teeb yuag, tiv thaiv - huab cua tsim nrog dav teb - ntawm - saib lo ntsiab muag rau kev siv txuas ntxiv.
Kev ntsuas kev nyab xeeb ntxiv:
Cov khaub ncaws tiv thaiv: Hnav hluav taws- cov tsho tiv thaiv kab mob thiab cov tsho ntev - cov ris tsho hnav kom npog cov tawv nqaij.
Laser Barriers: Txhim kho tsis yog- cov ntaub thaiv npog qhov cuam tshuam nyob ib puag ncig thaj chaw kho mob kom muaj lub teeb tsis pom kev.
Kev cob qhia: Cov neeg ua haujlwm yuav tsum tau txais daim ntawv pov thawj laser kev cob qhia kev nyab xeeb kom nkag siab txog cov txheej txheem xwm txheej ceev thiab cov cuab yeej siv.
Tshaj tawm - Kev Kho Mob thiab Ntev - Kev Tiv Thaiv Lub Sij Hawm
Tom qab pico laser kho, cov neeg mob yuav tsum ua raws li cov lus qhia no kom txo tau cov teeb meem:
Kev Tiv Thaiv Hnub Ci: Siv dav -spectrum SPF 50+ tshuaj pleev thaiv hnub txhua hnub thiab hnav lub kaus mom lossis UV- thaiv cov iav sab nraum zoov.
Hydration thiab Kho: Siv cov tshuaj moisturizers los txhawb cov tawv nqaij barrier rov qab. Tsis txhob hnyav exfoliants tsawg kawg yog ob lub lis piam.
Ua raws li-Kev Saib Xyuas: Qhia txog qhov mob liab, o, lossis kev hloov hauv lub zeem muag mus rau tus kws kho mob tam sim ntawd.
FAQ: Cov Lus Nug Txog Kev Nyab Xeeb Laser
Q1: yog vim li caspico laser kev nyab xeeb dua li ib txwm lasers?
A1: Pico lasers siv ultra- cov pulses luv luv kom txo tau cov cua sov, txo cov ntaub so ntswg puas tsuaj thiab ua kom zoo.
Q2: Cov looj tsom iav dub puas tuaj yeem tiv thaiv kev raug laser?
A2: No. Regular sunglasses lack the optical density and wavelength-specific filters required to block laser radiation. Ib txwm siv ntawv pov thawjlaser tsom iav tsom iav.
Q3: Yuav tsum tau npaum li caslaser tsom iav tsom iavhloov?
A3: Hloov cov tsom iav yog tias cov lo ntsiab muag tau khawb, tsis muaj xim, lossis yog tias lawv qhov ntsuas tiv thaiv dhau los dhau los. Ua raws li cov chaw tsim khoom cov lus qhia rau kev saib xyuas.
