Kwiminyaka emininzi, i-laser ibe sisixhobo esisekwe kakuhle ekuphuhliseni nasekuveliseni iindawo zonyango.Apha, ngokunxuseneyo nezinye iindawo zokusetyenziswa kwemizi-mveliso, iilaser zefiber ngoku zifumana isabelo esongezelelekileyo sentengiso.Kutyando olungenelelayo oluncinci kunye nokufakelwa kwe-miniaturized, uninzi lweemveliso zesizukulwana esilandelayo ziba ncinci, zifuna ukusetyenzwa kwempahla- kwaye itekhnoloji yelaser sisisombululo esifanelekileyo sokuhlangabezana neemfuno ezizayo.
Ukusikwa kwe-laser yentsimbi echanekileyo ngokuchanekileyo bubuchwephesha obufanelekileyo kwiimfuno ezikhethekileyo zokusika ezifunyenwe kukwenziwa kwezixhobo zetyhubhu yezonyango kunye namalungu, afuna uluhlu lweempawu ezisikiweyo ezinencam ezibukhali, iikhonto, kunye neepateni ngaphakathi kwemiphetho.Ukusuka kwizixhobo zotyando ezisetyenziselwa ukusika kunye ne-biopsy, ukuya kwiinaliti eziqulethe iingcebiso ezingaqhelekanga kunye nokuvulwa kweendonga ezisecaleni, ukuya kwi-puzzle chain linkages kwii-endoscopes eziguquguqukayo, ukusika kwe-laser kunika ukuchaneka okuphezulu, umgangatho, kunye nesantya kuneteknoloji yokusika esetyenziswa ngokwesiko.

Imingeni yoshishino lwezonyango
Ishishini lezonyango linika imingeni ekhethekileyo kubavelisi bamalungu achanekileyo.Ayizizo kuphela izicelo ezisika umphetho, kodwa zifuna ngokwemiqathango yokulandeleka, ukucoceka, kunye nokuphinda-phinda.Ilaser yegolide inezixhobo, amava, kunye neenkqubo zokubonelela abathengi bethu ngezona mveliso zikumgangatho ophezulu ngeyona ndlela ithembekileyo nesebenzayo.
Iinzuzo zokusika iLaser
I-laser ilungele ukusika kwezonyango, kuba i-laser inokujoliswa phantsi ukuya kwi-0.001-intshi ubukhulu bendawo yendawo enikezela ngenkqubo yokusika i-non-contact "engaphantsi kwesixhobo" kwisantya esiphezulu kunye nesisombululo esiphezulu.Njengoko isixhobo sokusika i-laser asithembeli ekuthinteni inxalenye, sinokuqhelaniswa ukwenza nayiphi na imilo okanye ifom, kwaye isetyenziselwa ukwenza iimilo ezizodwa.
Akukho nxalenye yokuphazamiseka ngenxa yeendawo ezincinci ezichaphazelekayo zobushushu
Isakhono esintsonkothileyo sokusika inxalenye
Iyakwazi ukusika iintsimbi ezininzi kunye nezinye izinto
Akukho sixhobo sinxitywa kwaye sikrazulwa
Iprototyping ekhawulezayo, engabizi kakhulu
Ukususwa kwe-burr okwehlisiwe
Isantya esiphezulu
Inkqubo engaqhagamshelwanga
Ukuchaneka okuphezulu kunye nomgangatho
Ilawuleka kakhulu kwaye ibhetyebhetye
Umzekelo, ukusika i-laser sisixhobo esigqwesileyo kwiityhubhu ezincinci, ezifana nezo zisetyenziselwa i-cannula kunye ne-hypo tube applications ezifuna uluhlu lweempawu ezifana neefestile, iindawo zokubeka, imingxuma kunye ne-spirals.Ngobungakanani bendawo egxininisiweyo ye-0.001-intshi (i-25 microns), i-laser inikezela ngokunqunyulwa kwesisombululo esiphezulu esisusa isixa esincinci sezinto ezivumela ukusika isantya esiphezulu ngokuchaneka kwe-dimensional efunekayo.
Kwakhona, ekubeni ukuqhutyelwa kwe-laser kungadibanisi, akukho mandla omatshini anikezelwa kwiityhubhu - akukho tyhala, ukutsala, okanye amanye amandla anokuthi agobe inxalenye okanye abangele i-flex enokuba nefuthe elibi kulawulo lwenkqubo.I-laser inokusekwa ngokuchanekileyo ngexesha lenkqubo yokusika ukulawula indlela eshushu ngayo indawo yokusebenza.Oku kubalulekile, kuba ubungakanani bamacandelo ezonyango kunye neempawu ezisikiweyo ziyancipha, kwaye iindawo ezincinci zinokutshisa ngokukhawuleza kwaye zinokutshisa ngokugqithiseleyo.
Ngaphezu koko, uninzi lwezicelo zokusika zezixhobo zonyango zikwinqanaba le-0.2-1.0 mm.Ngenxa yokuba iijiyometri ezisikiweyo zezixhobo zonyango ziqhelekile, iilaser zefayibha ezisetyenziswa kwimveliso yesixhobo sonyango zisebenza rhoqo kulawulo lokubetha kwentliziyo.Umgangatho wamandla ophakamileyo kufuneka ube ngaphezulu kakhulu kwinqanaba le-CW ukunciphisa ubushushu obushiyekileyo buchaphazela ngokususa imathiriyeli esebenza ngokufanelekileyo, ngakumbi kwiindawo ezinqamlezileyo ezityebileyo.
Isishwankathelo
Iifiber lasers zithe gqolo ukufaka ezinye iingqikelelo zelaser kwimveliso yezixhobo zonyango.Ulindelo lwangaphambili, ukuba usetyenziso lokusika alunakuphendulwa ngeelaser zefiber kungekudala, kwafuneka ukuba zihlaziywe kudala.Ke ngoko, izibonelelo zokusika i-laser ziya kuba negalelo ekukhuleni okukhulu kokusetyenziswa kokusikwa ngokuchanekileyo kwimveliso yesixhobo sonyango kwaye lo mkhwa uya kuqhubeka kwiminyaka ezayo.
