Kwa zaka zambiri, ma laser akhala chida chodziwika bwino pakupanga ndi kupanga zida zachipatala. Pano, mofanana ndi madera ena ogwiritsidwa ntchito m'mafakitale, ma fiber laser tsopano akupeza gawo lalikulu pamsika. Pa opaleshoni yosavulaza kwambiri komanso zoyikamo zazing'ono, zinthu zambiri zam'badwo wotsatira zikuchepa, zomwe zimafuna kukonza zinthu mosamala kwambiri - ndipo ukadaulo wa laser ndiye njira yabwino yokwaniritsira zofunikira zomwe zikubwera.
Kudula laser yopyapyala ndi ukadaulo woyenera kwambiri wopangira zida zapadera zodulira zomwe zimapezeka popanga zida ndi zida zamachubu azachipatala, zomwe zimafuna zinthu zosiyanasiyana zodulira zokhala ndi m'mbali zakuthwa, mawonekedwe, ndi mapatani mkati mwa m'mbali. Kuyambira zida zopangira opaleshoni zomwe zimagwiritsidwa ntchito podula ndi biopsy, mpaka singano zokhala ndi nsonga zachilendo ndi mipata yam'mbali mwa khoma, mpaka kulumikizana kwa unyolo wa ma endoscope osinthika, kudula laser kumapereka kulondola kwambiri, khalidwe, komanso liwiro kuposa ukadaulo wodulira womwe umagwiritsidwa ntchito nthawi zambiri.
Makina odulira ang'onoang'ono a GF-1309 a laser ku Colombia opangira stent yachitsulo
Mavuto a makampani azachipatala
Makampani azachipatala amapereka zovuta zapadera kwa opanga zida zolondola. Sikuti mapulogalamuwa ndi apamwamba kokha, komanso amafunikira kwambiri pankhani yolondola, ukhondo, komanso kubwerezabwereza. Laser yagolide ili ndi zida, luso, ndi machitidwe kuti apatse makasitomala athu zinthu zabwino kwambiri m'njira yodalirika komanso yothandiza kwambiri.
Ubwino wodula ndi laser
Laser ndi yabwino kwambiri podula zinthu zachipatala, chifukwa laser imatha kuyikidwa pansi mpaka kukula kwa malo okwana mainchesi 0.001 omwe amapereka njira yabwino yodulira "yopanda zida" popanda kukhudzana ndi chinthucho mwachangu komanso mopanda kukayikira. Popeza chida chodulira laser sichidalira kukhudza gawolo, chimatha kulunjika kuti chipange mawonekedwe kapena mawonekedwe aliwonse, ndikugwiritsidwa ntchito popanga mawonekedwe apadera.
Palibe kusokonekera kwa gawo chifukwa cha madera ang'onoang'ono omwe akhudzidwa ndi kutentha
Luso lovuta lodula magawo
Imatha kudula zitsulo zambiri ndi zinthu zina
Palibe kuwonongeka ndi kung'ambika kwa zida
Kupanga zitsanzo mwachangu komanso zotsika mtengo
Kuchotsa burr kochepetsedwa
Liwilo lalikulu
Njira yosalumikizana
Kulondola kwambiri komanso khalidwe labwino
Yosinthasintha komanso yosinthasintha kwambiri
Mwachitsanzo, kudula kwa laser ndi chida chabwino kwambiri cha machubu ang'onoang'ono, monga omwe amagwiritsidwa ntchito popanga ma cannula ndi ma hypo tube omwe amafunikira zinthu zosiyanasiyana monga mawindo, mipata, mabowo ndi zozungulira. Ndi kukula kwa malo olunjika a mainchesi 0.001 (25 microns), laser imapereka kudula kwakukulu komwe kumachotsa zinthu zochepa kuti zitheke kudula mwachangu malinga ndi kulondola kofunikira.
Komanso, popeza kukonza kwa laser sikukhudza, palibe mphamvu yamakina yomwe imayikidwa pamachubu - palibe kukankhira, kukoka, kapena mphamvu ina yomwe ingapindire gawo kapena kuyambitsa kusinthasintha komwe kungayambitse kusinthasintha komwe kungayambitse kusokoneza kwa njira. Laser ikhozanso kukhazikitsidwa bwino panthawi yodula kuti iwongolere kutentha kwa malo ogwirira ntchito. Izi ndizofunikira, chifukwa kukula kwa zida zamankhwala ndi mawonekedwe odulidwawo kukuchepa, ndipo zigawo zazing'ono zimatha kutentha mwachangu ndipo mwina zimatha kutentha kwambiri.
Kuphatikiza apo, ntchito zambiri zodulira zida zachipatala zili pakati pa 0.2–1.0 mm. Popeza ma geometries odulira zida zachipatala nthawi zambiri amakhala ovuta, ma laser a ulusi omwe amagwiritsidwa ntchito popanga zida zachipatala nthawi zambiri amagwiritsidwa ntchito modulated pulse regime. Mphamvu yayikulu iyenera kukhala pamwamba pa CW kuti muchepetse kutentha kotsala kudzera mu kuchotsa zinthu bwino, makamaka m'magawo okhuthala.
Chidule
Ma laser a fiber akupitilizabe kusintha malingaliro ena a laser popanga zida zamankhwala. Zomwe tinkayembekezera kale, kuti kugwiritsa ntchito kudula sikungathetsedwe ndi ma laser a fiber posachedwa, zidasinthidwa kale kwambiri. Chifukwa chake, ubwino wodula laser udzathandizira kukula kwakukulu pakugwiritsa ntchito kudula kolondola popanga zida zamankhwala ndipo izi zipitilira m'zaka zikubwerazi.
