Ikoreshwa n'Ibyiza by'Ikoranabuhanga rya FAC mu Gukuraho Imisatsi rya 808nm
FAC (Fast Axis Collimation) ni ikoranabuhanga rigezweho laser Ikoranabuhanga rya optique rikoreshwa by'umwihariko ku bikoresho byo gukuraho umusatsi bya laser bya 808nm. Mu guhindura imiterere y'umuyoboro wa laser, binoza cyane imikorere n'ubushobozi bwo gukuraho umusatsi. Iri koranabuhanga rigaragaza iterambere rikomeye mu bijyanye n'ibikoresho byo kwisiga bya laser, ritanga salon z'ubwiza zibigize umwuga igisubizo cyiza kandi gitekanye cyo gukuraho umusatsi.
Igishushanyo mbonera cy'ibanzeIple y'ikoranabuhanga rya FAC Energy Concentration
Ikoranabuhanga rya FAC rikoresha sisitemu yihariye y'ijisho ry'urumuri kugira ngo ikandagire vuba umuyoboro wa laser, yinjiza umuyoboro wa laser utandukanye mbere mu muyoboro w'ingufu nyinshi. Mu bikoresho byo gukuraho umusatsi bya 808nm, iri koranabuhanga rituma ingufu za laser zireba neza agace k'umusatsi kagenewe, bigabanya igihombo cy'ingufu mu gihe cyo kohereza. Ugereranyije n'uburyo busanzwe bwo gusohora umuriro wa laser, ikoranabuhanga rya FAC rishobora kongera ubushobozi bwo gusohora ingufu ku kigero kirenga 20%. Uku kugenzura ingufu neza gutuma laser ya 808nm y'uburebure bwo hejuru yinjira mu ruhu, ikagera ku gasongero k'uruhu, mu gihe yirinda kwangirika k'ubushyuhe ku ngingo zikikije.
Isesengura ry'Ibyiza bya Tekiniki
**1. Uburyo bwo kuvura bwazamutse cyane**
Ikoranabuhanga rya FAC, hamwe n'uburebure bwa 808nm, ritanga umuvuduko wihuta cyane wo gukuraho umusatsi ku isoko. Ingano nini cyane ya 12 × 20cm, hamwe n'umuvuduko wo hejuru wa 10Hz, bigabanya cyane igihe cyo kuvurwa. Amakuru y'ubuvuzi agaragaza ko ibikoresho bikoresha ikoranabuhanga rya FAC bishobora kuvura ubuso bw'umubiri bwa 30% kurusha ibikoresho bisanzwe mu gihe kimwe, bigatuma biba byiza cyane mu gukuraho umusatsi ahantu hanini nko mu mugongo no ku maguru.
**2. Ingufu nyinshi zihoraho**
Ibikoresho gakondo bya laser bihura n’ihindagurika ry’ingufu, mu gihe ikoranabuhanga rya FAC rigera ku muvuduko w’ingufu wa "square wave", rikuraho imbaraga nyinshi mu ntangiriro y’ingufu n’igabanuka ry’ingufu ku iherezo. Uku gukwirakwiza ingufu guhamye gutuma buri gusohora impuzandengo kugera ku gaciro kagenwe, bigatuma habaho ibisubizo bimwe kandi bihoraho mu kuvura, birinda ubushye bw’uruhu cyangwa kutagira uburyo buhagije bwo kuvura buterwa n’ikwirakwizwa ry’ingufu ritari rikwiye.
**3. Kwizeza umutekano n'ihumure kabiri**
Ingufu nyinshi z’ikoranabuhanga rya FAC zemerera igikoresho kugera ku ngaruka imwe yo kuvura hamwe n’ingufu nkeya. Iyo kivanze na sisitemu yo gukonjesha ya safiro, gikomeza ubushyuhe bw’uruhu kuri dogere selisiyusi 5. Ubu buryo bwo "gukonjesha" bukuraho ubushyuhe n’ububabare bijyana no gukuraho umusatsi hakoreshejwe laser, bigatuma uburyo bwo kuvura burushaho kuba bwiza kandi bukwiriye ahantu horoshye nko kuryama mu gituza no mu maso.
**4. Ibimenyetso byinshi**
Ubuso bw'umurambararo bwa 808nm bufite ubushobozi bwiza bwo kwinjira mu ruhu no guhitamo uburyo bwo kwinjiza melanin. Iyo buhujwe n'ikoranabuhanga rya FAC, bushobora kuvura ubwoko butandukanye bw'umusatsi mu buryo bwizewe kandi bunoze, kuva ku bwoya bworoshye, bworoshye kugeza ku bwoya bukomeye kandi bukomeye. Byongeye kandi, ubu buryo bushobora gukoreshwa cyane n'ubwoko butandukanye bw'uruhu (ubwoko bwa Fitzpatrick I-VI), harimo uruhu rwijimye n'uruhu rwangiritse ku zuba, bigoye kuvura hakoreshejwe laser gakondo.
**5. Inyungu zikomeye mu bukungu bw'igihe kirekire**
Ikoresheje inkoni ya laser ifite imbaraga nyinshi ya 2000W yatumijwe muri Coherent Lasers, hamwe n'ikoranabuhanga rya FAC, iyi mashini ifite ubuzima burenga miliyoni 50 z'amapine. Uku kuramba kwayo kugabanya cyane ikiguzi cyo gusimbuza ibikoresho n'ikiguzi cyo kubungabunga salons zo mu rwego rwo hejuru, mu gihe bitanga umusaruro urambye kandi uhoraho mu kuvura.
Imikorere y'ikoreshwa ry'ubuvuzi
Mu buvuzi, igikoresho cyo gukuraho umusatsi cya 808nm gifite ikoranabuhanga rya FAC gikunze gukuraho umusatsi hafi ya wose mu buryo bungana n’inshuro 4-6 gusa. Nyuma yo kuvurwa, kongera gukura k’umusatsi bimara igihe kirekire, aho umusatsi mushya urushaho kuba mwiza, woroshye, kandi imyenge ikaba mito. Ugereranyije n’ibikoresho bisanzwe bya IPL cyangwa laser ifite uburebure bwa wavelength imwe, igikoresho cyo gukuraho umusatsi cya 808nm gifite ikoranabuhanga rya FAC kigabanya ukwezi k’ubuvuzi ho 30%-40% mu gihe cyongera kunyurwa kw’abakiriya ho hejuru ya 25%.
Uruvange rwiza rw'ikoranabuhanga rya FAC rikoresha ingufu n'uburebure bwa 808nm bigaragaza ubuhanga bugezweho mu gukuraho umusatsi hakoreshejwe laser. Ntabwo bikemura gusa imikorere mibi, ububabare bukabije, n'ibimenyetso bike by'ibikoresho gakondo byo gukuraho umusatsi, ahubwo binatanga igisubizo cya tekiniki gihanganirwa cyane ku ma salon yo kwisiga. Kubera ko abaguzi barushaho gukenera gukuraho umusatsi mu buryo butababaza, bwihuse kandi burambye, iri koranabuhanga ryiteguye kuba ikintu gisanzwe mu bikoresho by'ubwiza by'umwuga.
