Q-hloov laser yog qhov zoo ntawm kev kho cov teeb meem pigment 1?

Q-switching thev naus laus zis yog ib qho ntawm cov thev naus laus zis tseem ceeb ntawm cov tshuab hluav taws xob siab zog.Nws yog ib lub tshuab tshwj xeeb los ua kom lub siab pulse zog los ntawm compressing lub laser tso zis mem tes dav.Rau feem ntau siv pulsed solid-state lasers, tom qab siv Q-hloov thev naus laus zis, lub sij hawm mem tes dav ntawm cov zis laser tuaj yeem compressed mus rau ib kaum-txhiab, thiab lub zog siab tuaj yeem nce mus rau ntau tshaj ib txhiab zaus.Yog li, qhov teeb meem pigmentation twg Q-hloov laser excel ntawm?
TheQ-hloov laser feem ntau siv cov kev xaiv photothermal nyhuv ntawm lub laser wavelength.Los ntawm kev xaiv lasers nrog txawv wavelengths, mem tes dav, thiab lub zog ceev, lub hom phiaj kev kho mob tuaj yeem tsom qhov tawg ntawm cov xim tsis muaj kev puas tsuaj rau cov ntaub so ntswg ib puag ncig kom ua tiav cov txiaj ntsig kho.Yog li ntawd, Q-hloov laser feem ntau yog siv los tshem tawm cov tawv nqaij pigmented, pigmentation los ntawm kev sib xyaw pigmentation, thiab kev puas tsuaj pigmentation.Exogenous pigments, epidermal thiab dermal pigments muaj cov nyhuv zoo dua.

Ota mole
Ota mole yog cov kab mob grey-xiav patchy uas tau piav qhia thawj zaug los ntawm Ota hauv xyoo 1936 thiab kis mus rau cov hlab ntsha trigeminal faib hauv sclera thiab ipsilateral sab.Nws feem ntau tshwm sim ntawm daim tawv muag sab sauv thiab sab qis, palate, thiab sab cev nqaij daim tawv ntawm lub ntsej muag, thiab qee zaus ntawm ob sab.Kwv yees li ob feem peb ntawm cov neeg mob muaj ipsilateral scleral xiav staining.Cov kab mob feem ntau yog patchy, thiab xim tuaj yeem yog xim av, turquoise, xiav, dub, lossis ntshav.Cov kev hloov pauv pathological yog: melanocytes nyob nruab nrab ntawm collagen fibers ntawm dermis txheej, thiab lawv yuav tsis rov qab, uas cuam tshuam rau cov tsos.
Lub hauv paus ntsiab lus ntawm Q-hloov laser kho ntawm Ota mole yog tias nws qhov tshwj xeeb wavelength ntawm laser zog yog xaiv absorbed los ntawm sib sib zog nqus melanin nyob rau hauv lub dermis, thiab nws luv luv pulse dav yam ntxwv txwv lub zog laser rau ntawm daim tawv nqaij.Cov kev txwv no muaj txiaj ntsig Kev sib xyaw ua ke tuaj yeem ua rau lub laser xaiv rhuav tshem cov dermal melanin hais thiab melanocytes, tawg rau hauv cov khoom, thiab raug phagocytosed los ntawm phagocytes, thiab kev puas tsuaj rau cov ntaub so ntswg ib txwm yuav luag xoom.
