Sekungamashumi eminyaka, ama-laser abe yithuluzi elisungulwe kahle ekuthuthukisweni nasekukhiqizeni izingxenye zezokwelapha.Lapha, ngokuhambisana nezinye izindawo zokufaka izicelo zezimboni, ama-fiber lasers manje athola isabelo semakethe enyuke kakhulu.Ngokuhlinzwa okuhlaselayo kancane kanye nokufakelwa okuncane, imikhiqizo eminingi yesizukulwane esilandelayo iya iba mincane, edinga ukucutshungulwa okubucayi kakhulu - futhi ubuchwepheshe be-laser buyisixazululo esifanelekile sokuhlangabezana nezidingo ezizayo.
Ukusika nge-laser yensimbi eqondile ecijile kuwubuchwepheshe obufaneleka bezidingo ezikhethekile zokusika ezitholakala ekukhiqizeni amathuluzi eshubhu lezokwelapha kanye nezingxenye, ezidinga izici eziningi ezisikiwe ezinemiphetho ebukhali, amakhonsathi, namaphethini ngaphakathi kwemiphetho.Kusukela kumathuluzi okuhlinza asetshenziswa ekusikeni nasekuhloleni i-biopsy, ukuya ezinalithini eziqukethe amathiphu angajwayelekile kanye nokuvuleka kodonga olusemaceleni, kuya ekuhlanganiseni iketango lama-endoscope aguquguqukayo, ukusika nge-laser kunikeza ukunemba okuphezulu, ikhwalithi, kanye nesivinini kunobuchwepheshe bokusika obusetshenziswa ngokwesiko.

Izinselelo zemboni yezokwelapha
Imboni yezokwelapha iletha izinselele eziyingqayizivele kubakhiqizi bezingxenye ezinemba.Akukhona nje kuphela ukuthi izinhlelo zokusebenza zihamba phambili, kodwa zifuna ngokulandela umkhondo, ukuhlanzeka, nokuphindaphinda.I-laser yegolide inemishini, isipiliyoni, kanye nezinhlelo ezikhona zokuhlinzeka amakhasimende ethu ngemikhiqizo esezingeni eliphezulu ngendlela enokwethenjelwa nangempumelelo ngangokunokwenzeka.
Izinzuzo zokusika i-laser
I-laser ilungele ukusikwa kwezokwelapha, ngoba i-laser ingagxilwa phansi ifike kusayizi wendawo ongu-0.001-intshi ohlinzeka ngenqubo yokusika “engenamathuluzi” enhle engathinteki ngesivinini esikhulu nangokulungiswa okuphezulu.Njengoba ithuluzi lokusika i-laser linganciki ekuthinteni ingxenye, lingaqondiswa ukwenza noma yikuphi ukuma noma ifomu, futhi lisetshenziselwa ukwenza izimo eziyingqayizivele.
Akukho ukuhlanekezela kwengxenye ngenxa yezindawo ezincane ezithintekile ukushisa
Ikhono eliyinkimbinkimbi lokusika izingxenye
Ingakwazi ukusika izinsimbi eziningi nezinye izinto
Akukho ukuguga kwamathuluzi
I-prototyping esheshayo, engabizi
Ukususwa kwe-burr okwehlisiwe
Ijubane eliphezulu
Inqubo yokungaxhumani nabo
Ukunemba okuphezulu kanye nekhwalithi
Kuyalawuleka kakhulu futhi kuyavumelana nezimo
Isibonelo, ukusika nge-laser kuyithuluzi elihle kakhulu lamashubhu amancane, njengalawo asetshenziselwa izinhlelo zokusebenza ze-cannula ne-hypo tube ezidinga izinto eziningi ezifana namafasitela, izikhala, izimbobo nama-spirals.Ngosayizi wendawo ogxilisiwe wamayintshi angu-0.001 (ama-microns angu-25), i-laser inikeza ukusikeka kokucaca okuphezulu okususa inani elincane lempahla ukuze kunikwe amandla ukusika kwesivinini esikhulu ngokuya ngokunemba kobukhulu obudingekayo.
Futhi, njengoba ukucutshungulwa kwe-laser kungekona ukuthintana, awekho amandla asetshenziswayo afakwa kumashubhu - awekho ukusunduza, ukudonsa, noma amanye amandla angase agobise ingxenye noma abangele ukugoba okungaba nomthelela omubi ekulawuleni inqubo.I-laser ingasethwa ngokunembile ngesikhathi sokusika ukuze kulawulwe ukuthi indawo yokusebenza ishisa kangakanani.Lokhu kubalulekile, ngoba usayizi wezingxenye zezokwelapha nezici ezisikiwe ziyancipha, futhi izingxenye ezincane zingashisa ngokushesha futhi zingase zishise kakhulu.
Ngaphezu kwalokho, izinhlelo zokusebenza eziningi zokusika zemishini yezokwelapha zikububanzi obuyi-0.2–1.0 mm.Ngenxa yokuthi ama-geometries esikiwe emishini yezokwelapha ngokuvamile ayinkimbinkimbi, ama-fiber lasers asetshenziswa ekukhiqizweni kwemishini yezokwelapha asebenza ngokujwayelekile ngohlelo lokushaya kwenhliziyo olushintshiwe.Izinga eliphezulu lamandla kufanele libe ngaphezu kweleveli ye-CW ukuze kuncishiswe ukushisa okusalayo kuthinteke ngokususa izinto ezisebenza kahle kakhulu, ikakhulukazi ezigabeni eziwugqinsi.
Isifinyezo
Ama-laser e-fiber ahlala eshintsha eminye imiqondo ye-laser ekukhiqizweni kwemishini yezokwelapha.Okulindelwe ngaphambilini, ukuthi izinhlelo zokusika ngeke zixazululeke ngama-fiber lasers esikhathini esizayo esiseduze, kudingeke ukuthi kubuyekezwe esikhathini eside esidlule.Ngakho-ke, izinzuzo zokusikwa kwe-laser zizofaka isandla ekukhuleni okukhulu ekusetshenzisweni kokusika okunembayo ekukhiqizeni idivayisi yezokwelapha futhi lo mkhuba uzoqhubeka eminyakeni ezayo.
