I-laser ye-fractional ayiyona insimbi entsha ye-laser, kodwa imodi yokusebenza ye-laser
I-lattice laser ayilona ithuluzi elisha le-laser, kodwa imodi yokusebenza ye-laser. Uma nje ububanzi be-laser beam (indawo) bungaphansi kwama-500um, futhi i-laser beam ihlezi ihlelwa ngendlela ye-lattice, imodi yokusebenza ye-laser ngalesi sikhathi I-laser eyingxenye.
Umgomo wokwelashwa kwe-laser oyingxenyana kusewumgomo wokukhetha isenzo se-photothermal, esibizwa ngokuthi umgomo wesenzo se-fractional photothermal: indlela yesenzo ye-laser ablation enkulu yendabuko iyalungiswa ukuze ububanzi bomugqa we-laser (indawo) bube buncane kune I-500um, kanye ne-laser beam Ihlelwe njalo ku-lattice, iphuzu ngalinye lidlala umphumela we-photothermal, futhi kukhona amangqamuzana esikhumba avamile phakathi kwamaphoyinti, adlala indima yokulungisa izicubu nokulungisa kabusha.
I-Carbon dioxide laser fractional ukwelapha izibazi
Ubude begagasi be-laser buhlobene eduze nomphumela wayo. II-CO2 laseringanikeza ubude begagasi “obungcono kakhulu”. I-CO2 laser eyingxenye ingabangela ukulimala kwesibazi esilinganiselwe futhi esilawulekayo, isuse ingxenye yesibazi, ilimaze futhi ivimbele imithambo yegazi esibazini, futhi ibangele ama-fibroblasts. I-Apoptosis, ikhuthaza ukuvuselelwa nokwakhiwa kabusha kwemicu ye-collagen, amandla ayo aphezulu makhulu, indawo yokulimala eseceleni ebangelwa ukushisa incane, izicubu ezihwamukile zinembile, ukulimala kwezicubu ezizungezile kulula, futhi isilonda se-laser singelapheka Izinsuku ezingu-3-5, okuholela e-hyperpigmentation noma i-hypopigmentation nezinye izinkinga Amathuba amancane okuthola lesi sifo, futhi athuthukise ukungalungi kokusabela okubi okukhulu (isibazi, i-erythema, isikhathi eside sokululama, njll.) kanye nomphumela ongabalulekile wokwelapha ngaphansi imodi ye-laser non-fractional, ebonisa ukuthi umphumela wokwelapha we-laser wezibazi uthuthuke kakhulu, futhi ingozi yokutheleleka iphansi. Inzuzo yokwelashwa okulula kwangemva kokuhlinzwa, okubonisa inqubo yokululama kusuka “esikhunjeni → esikhunjeni”.
I-laser ye-fractional inokuphepha nokusebenza okungcono ngokushesha nangesikhathi eside kune-laser ye-Er ablative, i-laser engashisi kanye nokuxebuka kwamakhemikhali, ngakho-ke i-carbon dioxide fractional laser ibhekwa kakhulu njengokwelashwa kwezibazi.
Njengamanje, izinkomba zokwelashwa kwe-carbon dioxide fractional laser yezibazi zinwetshwe kakhulu uma kuqhathaniswa nezindlela zendabuko.
Ukwelashwa kwelaser kwangaphambi kwesikhathi kwe-CO2 kwezibazi kulungele ikakhulukazi izibazi ezivuthiwe. Okwamanje, izinkomba zokwelashwa kwe-carbon dioxide fractional laser yezibazi yilezi: ① Ukwelashwa kwezibazi ezikha phezulu ezakhekile, izibazi ze-hypertrophic kanye nezibazi zokufinyela ezithambile. ②Inqubo yokuphola kwesilonda kanye nokusetshenziswa kusenesikhathi ngemva kokuphola kungashintsha inqubo yokuphila kwesilonda futhi kuvimbele isibazi sesilonda. ③Ukutheleleka kwesibazi, isilonda nesilonda esingamahlalakhona, isilonda sokusha esiyinsalela.
I-Carbon dioxide fractional laser treatment yezibazi kufanele ilashwe kanye njalo ezinyangeni ezi-3 noma ngaphezulu
Ukwelashwa kwe-carbon dioxide fractional laser yezibazi kufanele kwenziwe kanye njalo ezinyangeni ezi-3 noma ngaphezulu. Umgomo uthi: ngemva kokwelashwa nge-laser ye-CO2 eyingxenye, kuthatha isikhathi esithile ukuze isilonda siphole futhi silungiswe. Enyangeni yesi-3 ngemva kokwelashwa, ukwakheka kwezicubu zesilonda ngemva kokwelashwa kwabuyela esimweni esiseduze nezicubu ezivamile. Ngokomtholampilo, kungabonakala ukuthi ukubonakala kwendawo yesilonda kuzinzile, ngaphandle kokubomvu nokushintsha umbala. Ngalesi sikhathi, kungcono ukuphinda unqume ngokusho kokuthola indawo yesilonda. imingcele yokwelashwa ukuze kuzuzwe imiphumela engcono. Ezinye izazi zenza ukwelashwa kabusha ngezikhathi ezithile zezinyanga ezi-1-2. Ngokombono wokuphulukiswa kwesilonda, ayikho inkinga ekwelapheni kwesilonda, kodwa mayelana nokuzinza kokululama kwesilonda kanye nokwenzeka kokunquma imingcele yokwelashwa kabusha, akukuhle njengesikhawu 3. Kungcono ukwelapha kanye ngenyanga. Eqinisweni, inqubo yokulungisa amanxeba kanye nokulungiswa kabusha kwezicubu kuthatha isikhathi eside, futhi kungcono ukuphinda welaphe isikhawu esingaphezu kwezinyanga ezi-3.
Ukusebenza kwe-carbon dioxide fractional laser treatment of scars kuthintwa yizici eziningi
Ukusebenza kahle kokwelashwa ngelaser ye-carbon dioxide laser ezibazini kuqinisekile, kodwa ukusebenza kwayo kuthinteka izici eziningi, futhi ezinye izimo zokwelashwa okungagculisi zingase zenzeke, okuholela ekutheni abanye odokotela nezinye iziguli zingabaze ukusebenza kwayo.
①Umphumela wokwelashwa nge-laser ezibazini uncike ezicini ezimbili: ngakolunye uhlangothi, ubuchwepheshe bokwelapha bukadokotela kanye nokwamukelwa kohlelo lokwelapha oluphusile; ngakolunye uhlangothi, yikhono lokuzilungisa lomuntu ogulayo.
② Phakathi nenqubo yokwelapha, inhlanganisela yama-lasers amaningi kufanele ikhethwe ngokuya ngokubonakala kwesibazi, noma i-laser efanayo kufanele ishintshelwe ekhanda lokwelapha futhi imingcele yokwelapha ilungiswe njengoba kudingeka.
③Ukwelashwa kwendawo yesilonda ngemva kokwelashwa nge-laser kufanele kuqiniswe, njengokusetshenziswa kwamafutha okugcoba amehlo okulwa namagciwane kanye neshubhu lesici sokukhula ukuze kuvinjelwe ukutheleleka nokukhuthaza ukuphola kwesilonda.
④Kusadingeka ukuthi ukhethe uhlelo lokwelapha lomuntu siqu ngokwesimo sesibazi, futhi kuhlanganiswe ukuhlinzwa, ukucindezela okunwebekayo, i-radiotherapy, umjovo ophakathi kwesibazi wamahomoni e-steroid, imikhiqizo yejeli ye-silicone kanye nokusetshenziswa kwangaphandle kwezidakamizwa ukuthuthukisa umphumela wokwelapha, nokusebenzisa. ukuvimbela nokwelashwa kwesibazi esibanzi. phatha.
Izindlela zokuthuthukisa umphumela wokwelapha we-carbon dioxide fractional laser treatment yezibazi
Izici ze-morphological of scars zihlukene, futhi izindlela zokwelashwa ezifanele zidinga ukukhethwa ngokuvumelana nezici zezibazi.
①Imodi ye-laser eyingxenye engaphezulu isetshenziselwa izibazi eziyisicaba, futhi imodi ye-laser ejulile isetshenziselwa izibazi ezishone kancane.
②Izibazi eziphumela kancane endaweni yesikhumba noma esikhunjeni esiphakanyisiwe emigodini kufanele zihlanganiswe nemodi ye-hyperpulse kanye nemodi ye-lattice.
③ Ukuze uthole izibazi eziphakanyisiwe ngokusobala, kusetshenziswa ubuchwepheshe be-laser bokwenziwa, futhi ukujula kokungena kwe-laser kufanele kuhambisane nokuqina kwesibazi.
④Izibazi ngokusobala ezicwile noma eziphakanyisiwe, nezibazi ezinokukhubazeka kwenkontileka kufanele zilungiswe kabusha noma zincishiswe ngokusikwa ngokuhlinzwa kuqala, bese zelashwa nge-laser eyingxenye ngemva kokuhlinzwa.
⑤Umjovo ongaphakathi esibazini noma ukusetshenziswa kwangaphandle kwe-triamcinolone acetonide noma i-Deprosone (ukwelashwa kwezidakamizwa nge-laser-introduction) kufanele kwengezwe ngesikhathi esifanayo sokwelashwa nge-laser ngezibazi eziphakeme ngokusobala noma amasayithi anezibazi.
⑥ Ukuvinjelwa kusenesikhathi kwe-hyperplasia yesibazi kungahlanganiswa ne-PDL, 560 nmOPT, 570 nmOPT, 590 nmOPT, njll. ukuze kuvinjwe i-vascular hyperplasia ezibazini ngokuya ngezimo zesibazi. Kuhlanganiswe nokwelashwa okuphelele okufana nezidakamizwa ezikhuthaza ukuphulukisa, ukwelashwa kokucindezela okunwebekayo, ukwelapha ngemisebe yomzimba, imikhiqizo yejeli ye-silicone kanye nokusetshenziswa kwangaphandle kwezidakamizwa, ukwelashwa okunamandla okubanzi kokuvimbela izibazi kanye nokwelashwa kuyasetshenziswa ukuze kuthuthukiswe umphumela wokwelapha.
I-Carbon dioxide fractional laser inomphumela omangalisayo wokwelapha ezibazini, futhi ikhuthaza ukuguqulwa kwesikhumba esinezibazi esikhumbeni esivamile esinezinkinga ezimbalwa.
Ukwelashwa kwe-carbon dioxide laser yezibazi kungathuthukisa kakhulu izimpawu nezimpawu zezibazi, futhi kuthuthukise kakhulu ukubukeka kwezibazi. Ngaphansi kwezimo ezijwayelekile, umsebenzi wesibazi ungathuthukiswa emahoreni ambalwa ngemva kokwelashwa, ukuzwa kokuluma kwesibazi kungathuthukiswa phakathi nezinsuku ezimbalwa, futhi umbala nokuthungwa kwesibazi kungathuthukiswa ngemva kwezinyanga ezingu-1-2. Ngemuva kokwelashwa okuphindaphindiwe, kulindeleke ukuthi kubuyele esikhumbeni esivamile noma Valene nesimo sesikhumba esivamile, ukwelashwa kusenesikhathi, umphumela ungcono.
Izinkinga eziyinhloko ze-carbon dioxide fractional laser ekuvimbeleni nasekwelapheni izibazi zihlanganisa i-erythema yesikhashana, ukutheleleka, i-hyperpigmentation, i-hypopigmentation, ukulunywa kwesikhumba sendawo, kanye ne-necrosis yesikhumba.
Ngokuvamile, i-carbon dioxide fractional laser iphephile futhi iyasebenza ekuvimbeleni nasekwelapheni izibazi, ezinezinkinga ezimbalwa noma ezithambile.
