1064nm Laser hauv kev kho mob tawv nqaij kom zoo nkauj
Cov yam ntxwv ntawm 1064nm yog dab tsi? qhov ntev ntawm qhov ntev cov lasers?
- Kev Taw Qhia rau 1064nm Lasers
Lub teeb 1064nm wavelength yog ib feem ntawm infrared spectrum thiab yog ib qho tshwj xeeb wavelength uas tuaj yeem nqus tau los ntawm dej, hemoglobin, melanin, thiab collagen fibers hauv dermis tib lub sijhawm. Txawm li cas los xij, qhov kev nqus ntawm 1064nm los ntawm peb lub chromophores no tsis muaj zog heev, yog li ntawd, 1064nm lasers muaj kev nkag mus tob thiab tuaj yeem kho cov kab mob vascular, pigmented, thiab collagen hauv dermis.
2.1064nm tuaj yeem faib ua:
Picosecond lasers: Picosecond pulse width. Lawv ua haujlwm zoo rau cov xim me me los ntawm kev siv photothermal thiab photomechanical effects. Picosecond lasers tau pom tias muaj txiaj ntsig zoo hauv kev kho mob daim duab koss, cov kab mob pigmented, thiab kev ua kom lub ntsej muag zoo nkauj.
Q-switched lasers: Nanosecond pulse width. Lawv yog cov kev xaiv zoo tshaj plaws rau kev kho cov tawv nqaij uas muaj xim tob dua xws li melasma, nevus of Ota, thiab xiav-xim av nevus.
Cov lasers ntev-pulse: Nrog rau qhov dav ntawm lub zog microsecond, lawv tuaj yeem ua rau muaj kev puas tsuaj los ntawm cua sov rau cov hlwb uas koj xav tau. Cov kev ntsuas qhov dav ntawm lub zog pulse tuaj yeem hloov kho tau, ua rau cov khoom no haum rau ntau yam kev siv hauv kev kho mob, thiab muab kev nyab xeeb thiab kev nplij siab thaum kho mob.
1064nm laser yog ib qho kev kho mob zoo nkauj uas nkag mus tob heev thiab siv tau dav, tshwj xeeb tshaj yog zoo rau kev txhim kho cov teeb meem pigmentation tob thiab cov kab mob ntawm cov hlab ntsha, thaum tseem muab cov tawv nqaij rov qab zoo thiab ua kom tawv nqaij khov kho. Nws tsom mus rau cov ntaub so ntswg uas xav tau los ntawm kev ua haujlwm photothermal xaiv, ua rau muaj kev puas tsuaj tsawg rau cov tawv nqaij ib puag ncig, ua rau lub sijhawm rov zoo luv luv, thiab tsim nyog rau ntau hom tawv nqaij.
Kev nkag mus tob: Mus txog rau hauv daim tawv nqaij dermis thiab txawm tias txheej subcutaneous los daws cov teeb meem pigmentation tob (xws li melasma) thiab cov hlab ntsha dilated (xws li rosacea).
Kev puas tsuaj tsawg kawg nkaus ntawm daim tawv nqaij: Qhov nqus melanin qis dua txo qhov kev pheej hmoo ntawm kev kub hnyiab ntawm daim tawv nqaij, ua rau nws tsim nyog dua rau cov neeg uas muaj cov tawv nqaij tsaus dua.
Ntau yam siv tau: Ib lub cuab yeej rau ntau yam siv; qhov dav thiab lub zog hloov kho tau los daws ntau yam teeb meem (xws li tshem tawm cov xim, rov ua kom tawv nqaij zoo nkauj, thiab tshem tawm cov plaub hau).
Txhawb kev tsim kho collagen: Lub zog thermal txhawb nqa kev tsim kho collagen hauv dermis, ua rau daim tawv nqaij zoo dua qub thiab ncua daim tawv nqaij sagging thiab cov kab zoo.
