Co2 Fractional Laser Tshuab Nqi

Cov pa roj carbon dioxide fractional laser yog cov roj laser. Nws lub hauv paus ntsiab lus ntawm kev ua yog focal photothermal nkaus. Lub fractional laser generates me me kab teeb nyob rau hauv ib tug array, uas ua rau lub dermis los txhawb zus tau tej cov dermal collagen thiab lub rearrangement ntawm collagen fibers. Cov pa roj carbon dioxide fractional laser yog kev txhim kho ntawm cov pa roj carbon dioxide laser. Carbon dioxide laser yog ib txwm laser. Txij li cov txheej txheem laser tsis muaj hom lattice, nws muaj qhov tsis zoo xws li kev puas tsuaj loj, lub sijhawm rov qab los ntev, thiab ntau yam kev mob tshwm sim. Fractional lasers tuaj yeem ua tau raws li qhov xav tau ntawm kev kho mob ntawm cov neeg mob sib txawv thiab cov kab mob mus rau qhov loj tshaj plaws, vim tias cov khoom siv laser fractional muaj qhov tunability ntawm ntau yam tsis zoo, xws li tunability ntawm qhov chaw txoj kab uas hla, tunability ntawm cov kev kho mob ceev, thiab tunability ntawm qhov chaw. kho qhov tob. , kev kho lub zog adjustability, thiab lwm yam, kom cov kab mob sib txawv tuaj yeem tau txais kev kho mob tus kheej, thiaj li tau txais cov nyhuv curative zoo tshaj plaws, uas yog lub ntsiab lus tiag tiag ntawm kev siv fractional laser. Fractional carbon dioxide laser yog cov roj laser. Lub hauv paus ntsiab lus ntawm kev txiav txim yog focal photothermal nkaus. Lub fractional laser tsim cov teeb me me teeb tsa hauv ib qho array. Tom qab ua yeeb yam ntawm daim tawv nqaij, ntau yam microscopic puas rau cov qauv peb-dimensional columnar yog tsim. Nyob ib ncig ntawm txhua qhov chaw raug mob micro, muaj cov ntaub so ntswg uas puas lawm, thiab nws cov keratinocytes tuaj yeem nkag mus sai sai ua rau lub zos kho tau sai. Rearrange collagen fibers thiab elastic fibers, thiaj li hais tias cov ntsiab lus ntawm hom I thiab hom III collagen fibers nyob ze rau qhov qub piv, thiab cov qauv ntawm pathological caws pliav cov ntaub so ntswg hloov, maj mam softens thiab restores elasticity. Cov pab pawg nqus dej tseem ceeb yog dej, thiab dej yog cov khoom tseem ceeb ntawm daim tawv nqaij, uas tuaj yeem ua kom sov collagen fibers, ntsws thiab degenerate, thiab induce qhov txhab kho nyob rau hauv lub dermis. Lub resulting collagen deposits orderly, txhawb lub proliferation ntawm collagen fibers, thiab txhawb lub rov qab ntawm daim tawv nqaij atrophic nti.
