Mmwenyemakina odulira ang'onoang'ono a laserzatsirizidwa pambuyo pogulitsa, kupanga stent kwachitika kawirikawiri, zipangizo zikuyenda bwino, ndipo stent yatsopano yatsala pang'ono kukonzedwa, koma mwadzidzidzi inatumiza pempho lothandizira luso.Vuto lili kuti, bwerani mudzawone wopanga amuna-mwayi ndi momwe mungatsatire.
Wogula atalowa m'malo mwa chubu cha nickel-titanium stent, panali vuto pakukonza zida.Tiyenera kuthandizira pakuwonongeka kwa parameter malinga ndi zojambula za stent zoperekedwa ndi kasitomala kuti atsimikizire kuti chithandizo chatsopanocho chikhoza kudulidwa bwino.Akatswiri athu anafufuza bwinobwino chithunzicho ndipo anapeza kuti chinali chosakwanira, choncho anachijambulanso.Chifukwa m'malo zipangizo chitoliro zopangira, m'mimba mwake deta si chimodzimodzi, bushing ndi chuck pa zida laser kudula makina ayenera m'malo, kudula kutalika ayenera kukonzanso debugging, pambuyo kutali atatu kutali kuganizira debugging ndi mphamvu laser. kuchotsa zolakwika, kudula mwalingaliro kuyenera kukhala kwachilendo.
Komabe, vuto latsopano linachitika poyesa kudula, zopangira sizingadulidwe kwathunthu.Pambuyo poyesa mosamala ndikuyerekeza ndi zojambulazo, injiniyayo adapeza kuti m'lifupi mwake m'lifupi mwa chithandizocho ndi 0.04mm yaying'ono kuposa kukula kwake.Deta ya m'lifupi mwake yoperekedwa ndi kasitomala inali 2.6mm, koma kukula kwenikweni kunali 2.64mm (Chithunzi 1 cha chithandizo), kotero chubu sichikhoza kudulidwa bwino, ndipo cholakwika cha 0.04 chinadziwikanso ndi zipangizo.Deta yapakati ikasinthidwa, vuto la kudula nickel-titanium stent limathetsedwa mosavuta.
Pambuyo popitiliza kudula mayeso, zidapezeka kuti pali zigamba pamunsi mwa mpeni wa stent (Chithunzi 2).Pambuyo pokonza kutalika kwa kudula ndi mphamvu ya laser kachiwiri, zigamba zambiri zinali zitapita, ndipo panalibe zigamba zazing'ono pamalo amodzi (Chithunzi 3).Pambuyo pokonza bwino mphamvu ya laser kachiwiri, zigambazo zidasowa, ndipo 2.64mm m'mimba mwake stent idadulidwa bwino bwino.
Pakalipano, stent ya nickel-titanium yapangidwa mochuluka kuti ipereke chithandizo chapamwamba kwa ogwiritsa ntchito ambiri omwe ali ndi matenda a mtima.Monga opereka chithandizo chamankhwala olondola a laser micromachining, tidzaphatikiza kufunikira kwa msika, kupitiliza kuwerengera zomwe zidachitika, ndikupanga zida zanzeru, zogwira mtima, zapamwamba zolondola kwambiri zamtima ndi stent micromachining ndi njira zothetsera ukadaulo wa stent.
