I-Ultrafast Laser Ikubona Kanjani Ukucutshungulwa Okunembayo Kwezisetshenziswa Zezokwelapha?

Umqedazwe we-COVID-19 ubangele ukwanda kwesidingo sokwelashwa, imithi kanye nezinto zokwelapha. Isidingo samaski, ama-antipyretics, ama-antigen reagents, ama-oximeter, amafilimu e-CT, neminye imithi ehlobene nemishini yezokwelapha kungenzeka siqhubeke. Ukuphila kuyigugu futhi abantu bazimisele ukusebenzisa imali ngokungagodli ekwelapheni, futhi lokhu sekudale imakethe yezokwelapha ebiza amakhulu ezigidi.

I-Ultrafast Laser Ibona Ukucutshungulwa Okunembayo Kwamadivayisi Ezokwelapha

I-Ultrafast laser isho i-pulse laser ububanzi bayo bepulse obuphumayo bungu-10⁻¹² noma ngaphansi kwezinga le-piccosecond. Ububanzi be-pulse obuncane kakhulu kanye nokuminyana kwamandla okuphezulu kwe-laser esheshayo kwenza kube nokwenzeka ukuxazulula izingqinamba ezijwayelekile zokucubungula ezifana nezindlela zokucubungula eziphezulu, ezinhle, ezibukhali, eziqinile nezinzima okunzima ukuzifeza. Ama-laser asheshayo asebenza kakhulu ekucutshungulweni okunembayo ku-biomedical, i-aerospace, nezinye izimboni.

Iphuzu lobuhlungu bokushisela kwezokwelapha + nge-laser ikakhulukazi lilele ebunzimeni bokushisela izinto ezingafani, umehluko wamaphuzu ancibilikayo, ama-coefficients okwandisa, ukuqhutshwa kokushisa okushisayo, umthamo wokushisa othize, kanye nezakhiwo ezibonakalayo zezinto ezingafani. Umkhiqizo unosayizi omncane omuhle, izidingo zokunemba okuphezulu, futhi udinga umbono osizayo wokukhulisa okuphezulu.

Iphuzu lobuhlungu bokusika kwezokwelapha + nge-laser ikakhulukazi ukuthi, ekusikeni kwezinto ezincane kakhulu (okuvame ukubizwa ngokuthi ukujiya<0.2mm), i-material ikhubazeka kalula, indawo yomphumela wokushisa inkulu kakhulu, futhi imiphetho ifakwe ikhabhoni ngokujulile; Kukhona ama-burrs, igebe elikhulu lokusika, futhi ukunemba kuphansi; Indawo encibilikayo eshisayo yezinto ezibolayo iphansi futhi izwela izinga lokushisa. Ukusikwa kwezinto eziphukayo kujwayele ukuchotshozwa, phezulu kunemifantu emincane, kanye nezinkinga ezisele zengcindezi, ngakho-ke izinga lokukhiqiza lemikhiqizo eqediwe liphansi.

Embonini yokucubungula impahla, i-ultrafast laser ingafinyelela ukunemba okuphezulu kanye nendawo encane kakhulu ethinteke ukushisa, iyenze ibe wusizo ekucubunguleni ezinye izinto ezizwela ukushisa, njengokusika, ukubhoboza, ukususwa kwezinto, i-photolithography, njll. ifanele ukucubungula izinto ezibonayo eziphukayo, izinto eziqinile, izinsimbi eziyigugu, njll. Kwezinye izinhlelo zokusebenza zezokwelapha ezifana nama-micro scalpels, ama-tweezers, nezihlungi ezincane, ukusika ukunemba kwe-laser kungafinyelelwa. Ingilazi yokusika ye-laser esheshayo ingasetshenziswa kumashidi engilazi, amalensi, nezingilazi ezincane ezisetshenziswa kwezinye izinsimbi zezokwelapha.

Indima yemishini engenelelayo kanye nengenele kancane ekusheshiseni ukwelashwa, ekwehliseni ukuhlupheka kwesiguli, kanye nokukhuthaza ukuphulukiswa ngeke ibukeke phansi. Kodwa-ke, kuya ngokuya kuba nzima ukucubungula lezi zinsimbi kanye nezingxenye ngamasu endabuko. Ngaphezu kokuba mncane ngokwanele ukuthi ungadlula ezicutshini ezintekenteke njengemithambo yegazi yomuntu, wenze izinqubo eziyinkimbinkimbi, futhi uhlangabezane nezidingo zokuphepha nekhwalithi, izici ezivamile zalolu hlobo lwedivayisi isakhiwo esiyinkimbinkimbi, udonga oluncane, ukugoqa okuphindaphindiwe, izidingo eziphakeme kakhulu izinga eliphezulu, kanye nesidingo esikhulu sokuzenzakalela. Ikesi elijwayelekile i-stent yenhliziyo, enembile kakhulu yokucubungula futhi ibibiza isikhathi eside.

Ngenxa yamashubhu odongeni azacile kakhulu ama-stents enhliziyo, ukucutshungulwa kwe-laser kuya ngokuya kufakwa esikhundleni sokusika okuvamile. Ukucutshungulwa kwe-laser sekuyiyona ndlela ekhethwayo, kodwa ukucutshungulwa kwe-laser okuvamile ngokusebenzisa ukuncibilika kwe-ablation kungaholela ochungechungeni lwezinkinga ezifana nama-burrs, ububanzi bemisele engalingani, ukukhishwa okukhulu kwendawo, nobubanzi bezimbambo ezingalingani. Ngenhlanhla, ukuvela kwe-picosecond ne-femtosecond lasers kuthuthukise kakhulu ukucutshungulwa kwama-stents enhliziyo futhi kwazuza imiphumela emihle kakhulu.

Ukusetshenziswa kwe-Ultrafast Laser ku-Medical Cosmetology

Ukuhlanganiswa okungenazihibe kobuchwepheshe be-laser nezinsizakalo zezokwelapha kuqhuba intuthuko eqhubekayo embonini yemishini yezokwelapha.Ubuchwepheshe be-laser obusheshayo busetshenziswe kakhulu ezindaweni zobuchwepheshe ezisezingeni eliphezulu njengamadivayisi ezokwelapha, izinsizakalo zezokwelapha, i-biopharmaceuticals, nezidakamizwa, okudlala indima ebalulekile. Ngaphezu kwalokho, ama-laser asheshayo aya ngokuya asetshenziswa ngqo emkhakheni wezokwelapha womuntu ukuthuthukisa izimpilo zeziguli. Ngokuphathelene nezinkambu zokufaka isicelo, ama-laser asheshayo asethwe ukuthi ahole ku-biomedicine, okuhlanganisa ezindaweni ezifana nokuhlinzwa kwamehlo, ukwelapha ngobuhle be-laser njengokuvuselela isikhumba, ukukhishwa kwe-tattoo, nokususwa kwezinwele.

Ubuchwepheshe be-laser busetshenziswe kabanzi ku-cosmetology yezokwelapha nokuhlinzwa isikhathi eside. Ngaphambilini, ubuchwepheshe be-excimer laser babuvame ukusetshenziselwa ukuhlinzwa kwamehlo e-myopia, kuyilapho i-CO2 ye-fractional laser yayincanyelwa ukususwa kwamafreckle. Kodwa-ke, ukuvela kwama-lasers asheshayo kuye kwawuguqula ngokushesha umkhakha. Ukuhlinzwa kwe-laser ye-Femtosecond sekuyindlela evamile yokwelapha i-myopia phakathi kwemisebenzi eminingi yokulungisa futhi kunikeza izinzuzo ezimbalwa phezu kokuhlinzwa kwe-excimer laser yendabuko, okuhlanganisa ukunemba okuphezulu kokuhlinzwa, ukungaphatheki kahle okuncane, kanye nemiphumela emihle kakhulu yokubuka yangemva kokuhlinzwa.

Ukwengeza, ama-lasers asheshayo asetshenziselwa ukususa i-pigment, ama-moles omdabu, nama-tattoos, ukuthuthukisa ukuguga kwesikhumba, nokugcina isikhumba sivuseleleka. Amathemba ekusasa lama-laser asheshayo emkhakheni wezokwelapha ayathembisa, ikakhulukazi ekuhlinzweni komtholampilo kanye nokuhlinzwa okungavamisile. Ukusetshenziswa kwemimese ye-laser ekukhipheni okunembile kwamaseli nezicubu ezinecrotic neziyingozi okunzima ukuzikhipha ngesandla ngommese kuyisibonelo esisodwa samandla obuchwepheshe.

I-TEYUi-laser chiller esheshayo Uchungechunge lwe-CWUP lunokunemba kokulawula izinga lokushisa okungu-±0.1°C namandla okupholisa angu-800W-3200W. Ingasetshenziselwa ukupholisa amalaser ezokwelapha asheshayo angu-10W-40W, ukuthuthukisa ukusebenza kahle kwemishini, ukunweba impilo yemishini, futhi kukhuthaze ukusetshenziswa kwama-laser ashesha kakhulu emkhakheni wezokwelapha.

Isiphetho

Ukusetshenziswa kwemakethe kwama-lasers asheshayo emkhakheni wezokwelapha kuyaqala, futhi kunamandla amakhulu okuthuthuka okuqhubekayo.
