Sekungamashumi eminyaka, ama-laser abe yithuluzi elisekelwe kahle ekuthuthukisweni nasekukhiqizweni kwezingxenye zezokwelapha. Lapha, kanye nezinye izindawo zokusetshenziswa kwezimboni, ama-laser e-fiber manje athola isabelo semakethe esikhule kakhulu. Ngokuhlinzwa okungangenisi kakhulu kanye nokufakelwa okuncane, imikhiqizo eminingi yesizukulwane esilandelayo iya ngokuya iba mincane, edinga ukucutshungulwa okubucayi kakhulu kwezinto ezibonakalayo - futhi ubuchwepheshe be-laser buyisisombululo esifanele sokuhlangabezana nezidingo ezizayo.
Ukusika nge-laser yensimbi encane ngokunemba kuyindlela efanele yobuchwepheshe bezidingo ezikhethekile zokusika ezitholakala ekukhiqizweni kwamathuluzi nezingxenye zeshubhu yezokwelapha, ezidinga izici eziningi zokusika ezinemiphetho ebukhali, ama-contour, namaphethini ngaphakathi kwemiphetho. Kusukela kumathuluzi okuhlinza asetshenziswa ekusikeni nasekuhlolweni kwezicubu, kuya ezinalitini eziqukethe amathiphu angavamile kanye nokuvuleka kodonga oluseceleni, kuya ekuhlanganiseni iketanga le-puzzle lama-endoscopes aguquguqukayo, ukusika nge-laser kunikeza ukunemba okuphezulu, ikhwalithi, kanye nesivinini kunobuchwepheshe bokusika obusetshenziswa ngokwesiko.

Izinselele zemboni yezokwelapha
Imboni yezokwelapha iletha izinselelo ezihlukile kubakhiqizi bezingxenye ezinembile. Akukhona nje kuphela ukuthi izinhlelo zokusebenza ziyashesha, kodwa futhi ziyadinga ukulandelelwa, ukuhlanzeka, kanye nokuphindaphindwa. I-Golden laser inemishini, ulwazi, kanye nezinhlelo ezikhona ukuze inikeze amakhasimende ethu imikhiqizo esezingeni eliphezulu ngendlela ethembekile nephumelelayo ngangokunokwenzeka.
Izinzuzo zokusika nge-laser
I-laser ilungele ukusika kwezokwelapha, ngoba i-laser ingagxiliswa phansi ibe yi-0.001-intshi ububanzi obuyi-spot enikeza inqubo yokusika "engenazo izinsimbi" engathintani ngesivinini esikhulu kanye nesisombululo esiphezulu. Njengoba ithuluzi lokusika le-laser linganciki ekuthinteni ingxenye, lingaqondiswa ukwenza noma yisiphi isimo noma isimo, futhi lisetshenziswe ukwenza izimo ezihlukile.
Akukho ukuphazamiseka kwengxenye ngenxa yezindawo ezincane ezithintekile ekushiseni
Ikhono eliyinkimbinkimbi lokusika izingxenye
Ingasika izinsimbi eziningi nezinye izinto
Akukho ukuguguleka kwamathuluzi
I-prototyping esheshayo nengabizi
Ukususwa kwe-burr okuncishisiwe
Ijubane eliphezulu
Inqubo yokungaxhumani
Ukunemba okuphezulu kanye nekhwalithi
Ilawuleka kakhulu futhi iguquguquka
Isibonelo, ukusika nge-laser kuyithuluzi elihle kakhulu lamashubhu amancane, njengalawo asetshenziselwa izinhlelo zokusebenza ze-cannula kanye ne-hypo tube ezidinga izici eziningi ezifana namafasitela, izikhala, imigodi kanye ne-spirals. Ngosayizi wendawo egxile ku-0.001-intshi (25 microns), i-laser inikeza ukusika okuphezulu okususa inani elincane lezinto ukuze kuvunyelwe ukusika ngesivinini esikhulu ngokuya ngokunemba okudingekayo.
Futhi, njengoba ukucubungula nge-laser kungathintani, akukho mandla okusebenza afakwa emapayipini - akukho ukusunduza, ukuhudula, noma amanye amandla angase agobe ingxenye noma abangele ukugoba okungaba nomthelela omubi ekulawuleni inqubo. I-laser ingabuye ibekwe ngokunembile ngesikhathi senqubo yokusika ukuze ilawule ukuthi indawo yokusebenza ishisa kangakanani. Lokhu kubalulekile, ngoba usayizi wezingxenye zezokwelapha kanye nezici zokusika uyancipha, futhi izingxenye ezincane zingashisa ngokushesha futhi zingase zishise kakhulu.
Ngaphezu kwalokho, iningi lezinhlelo zokusebenza zokusika zamadivayisi ezokwelapha lisebangeni lokujiya elingu-0.2–1.0 mm. Ngenxa yokuthi amajiyometri okusika amadivayisi ezokwelapha ngokuvamile ayinkimbinkimbi, ama-fiber laser asetshenziswa ekukhiqizeni amadivayisi ezokwelapha avame ukusebenza ngendlela yokushaya kwenhliziyo okuguquliwe. Izinga lamandla aphezulu kumele libe ngaphezu kakhulu kwezinga le-CW ukuze kuncishiswe ukushisa okusele ngokususwa kwezinto okusebenzayo, ikakhulukazi ezindaweni ezibanzi.
Isifinyezo
Ama-laser e-fiber ahlala efaka eminye imiqondo ye-laser ekukhiqizweni kwamadivayisi ezokwelapha. Okwakulindelwe ngaphambilini, ukuthi izinhlelo zokusika ngeke zixazululwe yi-laser ye-fiber esikhathini esizayo esiseduze, kwadingeka zibuyekezwe kudala. Ngakho-ke, izinzuzo zokusika nge-laser zizosiza ekukhuleni okukhulu kokusetshenziswa kokusika ngokunemba ekukhiqizweni kwamadivayisi ezokwelapha futhi lo mkhuba uzoqhubeka eminyakeni ezayo.
