Chii chinonzi laser?
A LASER (light amplification by stimulated emission of radiation) inoshanda nekubudisa wavelength yechiedza chesimba guru, iyo kana yakatarisa pane imwe ganda mamiriro ekugadzira kupisa uye kuparadza masero anorwara. Wavelength inopimwa nemananometers (nm).
Mhando dzakasiyana dze lasers dziripo kuti dzishandiswe mukuvhiya ganda. Ivo vanosiyaniswa nepakati inogadzira iyo laser beam. Imwe neimwe yemhando dzakasiyana dzema lasers ine chaiyo siyana yekushandisa, zvichienderana newavelength yayo uye kupinda. Iyo yepakati inokudza chiedza cheimwe wavelength painopfuura nepairi. Izvi zvinoguma nekusunungurwa kwe photon yechiedza sezvainodzokera kune imwe nyika yakagadzikana.
Kureba kwemapuruzi emwenje kunokanganisa kushandiswa kwelaser yekiriniki mukuvhiya ganda.
Chii chinonzi alexandrite laser?
Iyo alexandrite laser inogadzira chaiyo wavelength yechiedza mune infrared spectrum (755 nm). Inofungidzirwamwenje dzvuku laser. Alexandrite lasers inowanikwawo muQ-switched mode.
Chii chinonzi alexandrite laser inoshandiswa?
Iyo US Chikafu neDrug Administration (FDA) yakabvumidza huwandu hwealexandrite laser michina inoburitsa infrared mwenje (wavelength 755 nm) kune akasiyana ganda kusagadzikana. Izvi zvinosanganisira Ta2 Eraser™ (Chiedza Zera, California, USA), Apogee® (Cynosure, Massachusetts, USA) uye Accolade™ (Cynosure, MA, USA), Michina yega yega inogona kugadzirwa zvakanyanya kuti itarise kune chaiwo matambudziko eganda.
Matambudziko anotevera eganda anogona kurapwa neAlexandrite laser matanda.
Vascular maronda
- *Spider neshinda tsinga kumeso nemakumbo, mamwe vascular birthmarks (capillary vascular malformations).
- *Kupomba kwechiedza kunonangidzira pigment dzvuku (hemoglobin).
- *Mavara ezera (solar lentigines), freckles, flat pigmented birthmarks (congenital melanocytic naevi), naevus yeOta uye akawana dermal melanocytosis.
- *Light pulses inotarisa melanin pakudzika kwakasiyana paganda kana paganda.
- *Light pulses inonangana nebvudzi follicle zvichiita kuti bvudzi ridonhe uye kuderedza kuwedzera kukura.
- *Inogona kushandiswa kubvisa bvudzi munzvimbo chero ipi zvayo kusanganisira muhapwa, bikini line, kumeso, mutsipa, musana, chipfuva nemakumbo.
- *Kazhinji haashande kune akareruka bvudzi bvudzi, asi anobatsira kurapa bvudzi rakasviba muvarwere veFitzpatrick mhando I kusvika III, uye pamwe mwenje-ruvara rudzi IV ganda.
- *Iyo yakajairika marongero anoshandiswa anosanganisira pulse durations ye2 kusvika 20 milliseconds uye fluences yegumi kusvika 40 J/cm.2.
- *Kuchenjerera kwakanyanya kunokurudzirwa muvarwere vane ganda rakatsvuka kana dema, sezvo laser inogona zvakare kuparadza melanin, zvichikonzera matinji machena eganda.
- *Kushandiswa kweQ-switched alexandrite lasers kwakavandudza maitiro ekubvisa tattoo uye nhasi kunoonekwa sechiyero chekutarisira.
- * Alexandrite laser kurapwa inoshandiswa kubvisa dema, bhuruu uye girini pigment.
- *Kurapwa kwelaser kunosanganisira kuparadzwa kwakasarudzika kweinki mamorekuru anozotorwa nemacrophages uye obviswa.
- *Iyo nguva pfupi yekupuruzira ye50 kusvika zana nanoseconds inobvumira laser simba kuti rivharwe kune tattoo particle (inenge 0.1 micrometres) zvinobudirira kupfuura refu-pulsed laser.
- *Simba rakakwana rinofanirwa kuendeswa panguva yega yega laser pulse kupisa iyo pigment kuti iparare. Pasina simba rakakwana mune imwe neimwe pulse, hapana pigment kupatsanurwa uye hapana kubviswa tattoo.
- * Ma tatoo asina kunyatso kubviswa nemamwe marapirwo anogona kupindura zvakanaka kune laser therapy, kupa kurapwa kwekutanga hakuna kukonzera mavanga akawandisa kana kukuvara kweganda.
