I-Alexandrite Laser 755nm

Yintoni i-laser?

I-LASER (ukwandiswa kokukhanya ngokukhutshwa kwemitha okukhuthazwayo) isebenza ngokukhupha ubude bokukhanya obunamandla aphezulu, okuthi xa kugxilwe kwimeko ethile yesikhumba kuya kudala ubushushu kwaye kutshabalalise iiseli ezinesifo. Ubude bokukhanya bulinganiswa ngee-nanometers (nm).

Iindidi ngeendidi zeelaser ziyafumaneka ukuze zisetyenziswe kutyando lolusu. Zahlulwe yindlela evelisa umqadi welaser. Uhlobo ngalunye lweeleser lunoluhlu oluthile loncedo, kuxhomekeke kubude bayo kunye nokungena kwayo. Le ndlela yokwandisa ukukhanya kobude be-wavelength ethile njengoko idlula kuyo. Oku kubangela ukukhululwa kwe-photon yokukhanya njengoko ibuyela kwimeko ezinzileyo.

Ubude bexesha lokukhanya kwe-pulses buchaphazela ukusetyenziswa kwe-laser kwizonyango zotyando lolusu.

Yintoni i-alexandrite laser?

I-laser ye-alexandrite ivelisa ubude bokukhanya obuthile kwi-infrared spectrum (755 nm). Ithathwa njengeilaser yesibane esibomvuIilaser zeAlexandrite ziyafumaneka nakwimowudi ye-Q-switched.

Isetyenziselwa ntoni i-alexandrite laser?

I-US Food and Drug Administration (FDA) ivumile uluhlu lweemashini ze-laser ze-alexandrite ezikhupha ukukhanya kwe-infrared (ubude be-wavelength 755 nm) kwiingxaki ezahlukeneyo zesikhumba. Ezi ziquka i-Ta2 Eraser™ (Light Age, eCalifornia, e-USA), i-Apogee® (eCynosure, eMassachusetts, e-USA) kunye ne-Accolade™ (eCynosure, MA, e-USA). Iimashini nganye zinokwenziwa ngokukodwa ukugxila kwiingxaki ezithile zesikhumba.

Ezi ngxaki zesikhumba zilandelayo zinokunyangwa nge-Alexandrite laser beams.

Izilonda zemithambo yegazi

• *Imithambo yesigcawu kunye nemithambo yoboya ebusweni nasemilenzeni, ezinye iimpawu zokuzalwa zemithambo yegazi (iingxaki zemithambo yegazi ye-capillary).
• *Iipulse ezikhanyayo zijolise kwi-pigment ebomvu (i-haemoglobin).
• *Amabala obudala (ii-solar lentigines), amabala okuzalwa, amabala okuzalwa anombala othe tyaba (i-congenital melanocytic naevi), i-naevus ye-Ota kunye ne-acquired dermal melanocytosis.
• *Iipulse ezikhanyayo zijolise kwi-melanin kubunzulu obuguquguqukayo eluswini okanye eluswini.
• *Ii-pulses ezikhanyayo zijolise kwi-follicle yeenwele ezibangela ukuba iinwele ziwe kwaye zinciphise ukukhula okungakumbi.
• *Ingasetyenziselwa ukususa iinwele nakweyiphi na indawo kuquka phantsi kwamakhwapha, umgca webhikini, ubuso, intamo, umqolo, isifuba kunye nemilenze.
• *Ngokubanzi ayisebenzi kakuhle kwiinwele ezinombala okhanyayo, kodwa iluncedo ekunyangeni iinwele ezimnyama kwizigulana zohlobo lweFitzpatrick I ukuya kolwesiThathu, mhlawumbi nolusu olunombala okhanyayo lwe-type IV.
• *Iindlela eziqhelekileyo ezisetyenziswayo ziquka ubude be-pulse obuzii-milliseconds ezi-2 ukuya kwezingama-20 kunye ne-fluences ezii-10 ukuya kwezingama-40 J/cm².
• *Kucetyiswa ukuba uqaphele kakhulu kwizigulane ezinesikhumba esintsundu okanye esimnyama, njengoko i-laser inokutshabalalisa i-melanin, nto leyo ebangela amabala amhlophe eluswini.
• *Ukusetyenziswa kwe-Q-switched alexandrite lasers kuyiphucule inkqubo yokususwa kwetattoo kwaye namhlanje ithathwa njengomgangatho wokhathalelo.
• *Unyango lwe-laser lwe-Alexandrite lusetyenziselwa ukususa umbala omnyama, oluhlaza okwesibhakabhaka noluhlaza.
• *Unyango lwelaser lubandakanya ukutshatyalaliswa okukhethekileyo kweemolekyuli zeinki ezithi emva koko zifunxwe zii-macrophages zize zisuswe.
• *Ubude bexesha elifutshane lokubetha kwentliziyo eliyi-50 ukuya kwi-100 nanoseconds livumela amandla e-laser ukuba agcinwe kwisuntswana le-tattoo (malunga ne-0.1 micrometers) ngokufanelekileyo kune-laser etyhalwayo ixesha elide.
• *Kufuneka kunikelwe amandla aneleyo ngexesha le-laser pulse nganye ukuze kufudunyezwe umbala ube yingceba. Ngaphandle kwamandla aneleyo kwi-pulse nganye, akukho qhekeko lombala kwaye akukho kususwa kwe-tattoo.
• *Iitatoo ezingakhange zisuswe ngempumelelo zezinye iindlela zonyango zinokusabela kakuhle kunyango lwelaser, ukuba unyango lwangaphambili aluzange lubangele amanxeba amaninzi okanye umonakalo wolusu.
