Khawv koob Fractional Laser

Dab tsi yog fractional laser?
Fractional laser tsis yog laser tab sis hais txog kev ua haujlwm ntawm lub laser.Raws li ntev raws li txoj kab uas hla ntawm lub laser beam (qhov chaw) yog tsawg tshaj li 500 μm, thiab lub laser beam yog tsis tu ncua teem rau hauv ib tug lattice, lub laser nyob rau lub sij hawm no lub sij hawm ua hauj lwm hom yog lub fractional laser.
Dab tsi yog fractional technology?
Ntau cov kev tshawb fawb tau pom tias cov qauv lattice, lattice ntom ntom, micropore loj, thiab micropore qhov tob cuam tshuam ncaj qha rau kev kho mob.Yog li ntawd, yuav ua li cas tswj cov lattice hom kom ua tiav cov txiaj ntsig zoo tshaj plaws yog qhov tseem ceeb ntawm txoj kev loj hlob ntawm cov lattice laser technology.Qhov tseeb fractional tso zis thev naus laus zis tau siv Computer Scanning Technology.Los ntawm cov computers thiab sophisticated optical scanners, cov kws kho mob tuaj yeem ncaj qha tswj cov fractional laser tso zis hom, nrog rau cov fractional loj, ntom, nrug, thiab cov duab.Txoj kab uas hla thiab qhov tob ntawm txhua qhov micro-qhov ua rau kev kho mob fractional laser ntau haum rau cov kev xav tau ntawm cov neeg mob.Qhov kev puas tsuaj tshwm sim yog qhov tsawg kawg nkaus invasive thiab tswj tau, txhim kho cov nyhuv kho, thiab txo cov kev mob tshwm sim.Lub dot matrix siv lub computer ntse laser scanning tshuab yog cov dot matrix tiag.

Lub hauv paus ntsiab lus ntawm fractional laser kho ntawm nti yog dab tsi?
Thefractional CO2 laser cov cuab yeej yog cov roj laser, thiab lub hauv paus ntsiab lus ntawm kev txiav txim yog "focal photothermal action".Lub fractional laser tsim arrays ntawm cov kab me me uas tau siv rau ntawm daim tawv nqaij los tsim cov chaw me me thermally puas nrog ntau cov qauv peb sab cylindrical.Muaj cov ntaub so ntswg tsis zoo nyob ib ncig ntawm txhua qhov chaw raug mob me me, thiab nws cov keratinocytes tuaj yeem nkag tau sai thiab ua kom nws zoo sai.Nws tuaj yeem ua rau collagen fibers thiab elastic fibers proliferate thiab rearrange, ua cov ntsiab lus ntawm hom I thiab hom III collagen fibers ze rau qhov qub piv, hloov cov qauv ntawm pathological caws pliav, maj mam soften thiab rov elasticity.Lub ntsiab haum ntawm cov fractional laser yog dej, thiab dej yog lub ntsiab ntawm daim tawv nqaij, uas yuav ua rau lub dermal collagen fibers yuav tsum rhuab mus shrink thiab denature, thiab induce lub qhov txhab kho cov tshuaj tiv thaiv nyob rau hauv lub dermis, lub collagen tsim nyob rau hauv. kom tso nyiaj, thiab txhawb kev loj hlob ntawm collagen, thiaj li txhim kho daim tawv nqaij elasticity thiab txo cov nti, lub ntsiab mechanisms muaj xws li: ① puas thiab inhibit cov hlab ntsha ntawm cov hlab ntsha hauv cov caws pliav;② vaporize thiab tshem tawm cov caws pliav;③ inhibit fibrous cov ntaub so ntswg ntau lawm thiab ntau heev proliferation;④ ua rau fibroblast apoptosis.
