755nm Alexandrite laser Yag laser yo gukuraho umusatsi tekinoroji

Amavu n'amavuko:Nubwo gukuramo umusatsi wa laser byakozwe mumyaka yashize kugirango bikureho cyangwa bigabanye umusatsi wijimye udashaka, ikoranabuhanga, harimo nuburyo bukwiye bwubwoko butandukanye bwuruhu hamwe nuduce twumubiri, ntabwo ryigeze rikorwa neza.

Intego:Turasubiramo amahame yo gukuraho umusatsi wa lazeri kandi dutanga raporo yubushakashatsi bwakozwe ku barwayi 322 babazwe imisatsi ya alexandrite ya alexandrite ya 3 cyangwa irenga hagati ya Mutarama 2000 na Ukuboza 2002. ubushakashatsi bwihuse.

Uburyo:Mbere yo kuvurwa, abarwayi basuzumwe na muganga bamenyeshwa uburyo, ingaruka n'ingaruka zishobora kuvurwa.Ukurikije ibyiciro bya Fitzpatrick, abarwayi bashyirwa muburyo bwuruhu.Abafite uburwayi bwa sisitemu, amateka yo kumva izuba, cyangwa gukoresha ibiyobyabwenge bizwi ko bitera fotosensitivite ntibakuwe mubuvuzi bwa laser.Ubuvuzi bwose bwakozwe hakoreshejwe lazeri ndende ya alexandrite laser ifite ubunini buhoraho (18 mm) na ubugari bwa ms 3, bwakoresheje nanometero 755 zingufu.Ubuvuzi busubirwamo mugihe gitandukanye bitewe nigice cyumubiri ugomba kuvurwa.

IBISUBIZO:Igiteranyo cyo gutakaza umusatsi cyagereranijwe ni 80.8% mubarwayi bose hatitawe ku bwoko bwuruhu.Nyuma yo kuvurwa, habaye ibibazo 2 bya hypopigmentation na 8 bya hyperpigmentation.Nta zindi ngorane zigeze zivugwa.UMWANZURO: Kuvura laser-pulse ndende ya alexandrite irashobora guhuza ibyifuzo byabarwayi bifuza kuvanaho umusatsi burundu.Kwipimisha neza abarwayi no kwigisha neza abarwayi mbere yubuvuzi nibyingenzi mukubahiriza abarwayi no gutsinda kwubuhanga.
Kugeza ubu, laseri z'uburebure butandukanye zikoreshwa mugukuraho umusatsi, kuva kuri 695 nm ruby ​​lazeri kumpera ngufi kugeza kuri 1064 nm Nd: YAG laser kumpera ndende.10 Nubwo uburebure bugufi butagera ku musatsi wigihe kirekire wifuza, uburebure burebure buri hafi cyane yikigereranyo cyo kwinjiza urumuri rwa ogisijeni ya hemoglobine na melanine kugirango ikore neza.Laser ya alexandrite, iherereye hafi yikigereranyo, ni amahitamo meza hamwe nuburebure bwa 755 nm.

Ingufu za laser zisobanurwa numubare wa fotone yagejejwe ku ntego, muri joules (J).Imbaraga z'igikoresho cya laser zisobanurwa nubunini bwingufu zitangwa mugihe, muri watts.Flux nubunini bwingufu (J / cm 2) zikoreshwa mukarere kamwe.Ingano yikibanza isobanurwa na diameter yumurambararo wa laser;Ingano nini itanga uburyo bwiza bwo guhererekanya ingufu binyuze muri dermis.

Kugirango ubuvuzi bwa lazeri bugire umutekano, imbaraga za lazeri zigomba gusenya umusatsi mugihe urinda ingirabuzimafatizo.Ibi bigerwaho mugukurikiza ihame ryigihe cyo kuruhuka ubushyuhe (TRT).Ijambo ryerekeza ku gihe cyo gukonjesha intego;Ibyangiritse byangiza ubushyuhe bigerwaho mugihe ingufu zitangwa ari ndende kurenza TRT yimiterere yegeranye ariko ikaba ngufi kuruta TRT yumusatsi, bityo ntibemere ko intego ikonja bityo bikangiza umusatsi.11, 12 Nubwo TRT ya epidermis yapimwe kuri ms 3, bisaba ms hafi 40 kugeza 100 kugirango umusatsi ukonje.Usibye iri hame, urashobora kandi gukoresha igikoresho gikonjesha kuruhu.Igikoresho cyombi kirinda uruhu kwangirika kwubushyuhe kandi bigabanya ububabare kumurwayi, bigatuma umukoresha atanga ingufu nyinshi.
