UmIndiyaumatshini wokusika i-laser microsele igqityiwe emva kokuthengiswa, ukuveliswa kwe-stent kuye kwaqhutywa ngokuqhelekileyo, izixhobo zisebenza kakuhle, kwaye i-stent entsha yezinto eziphathekayo sele iza kulungiswa ukuveliswa, kodwa ngokukhawuleza yathumela isicelo senkxaso yobugcisa.Iphi ingxaki, yiza ubone umenzi amadoda-ithamsanqa yindlela yokulandela.
Emva kokuba umthengi ethathe indawo ye-tube ye-nickel-titanium stent, kwakukho ingxaki kwi-debugging yezixhobo.Sidinga ukuncedisa kwi-parameter debugging ngokwemizobo ye-stent enikezelwa ngumthengi ukuqinisekisa ukuba inkxaso entsha inokunqunyulwa ngokuqhelekileyo.Iinjineli zethu zawujonga ngenyameko umzobo zaza zafumanisa ukuba umzobo awuphelelanga, ngoko ke zawuphinda ngokutsha.Ngenxa yokutshintshwa kwezinto ezikrwada zombhobho, idatha yobubanzi ayifani, i-bushing kunye ne-chuck kwisixhobo somatshini wokusika i-laser kufuneka itshintshwe, ukuphakama kokusika kukwafuna ukulungiswa kwakhona, emva kokude ukude kugxilwe kugxininiso olukude kunye namandla e-laser. ukulungisa ingxaki, ukusika ngokwethiyori kufuneka kube yinto eqhelekileyo.
Nangona kunjalo, ingxaki entsha yenzeke kwinkqubo yokusika uvavanyo, izinto eziluhlaza azikwazi ukunqunyulwa ngokupheleleyo.Emva kokulinganisa ngokucokisekileyo kunye nokuthelekisa kunye nemidwebo, injineli yafumanisa ukuba ububanzi bobubanzi benkxaso yayiyi-0.04mm encinci kunobukhulu bangempela.Idatha yobubanzi bobubanzi obunikezelwe ngumthengi ngu-2.6mm, kodwa ubukhulu bokwenene bebuyi-2.64mm (Umfanekiso 1 wenkxaso), ngoko ityhubhu ayinakunqunyulwa ngokuqhelekileyo, kwaye iphutha le-0.04 lifunyenwe zixhobo.Emva kokulungiswa kwedatha yobubanzi, ingxaki yokusika i-nickel-titanium stent ixazululwa ngokulula.
Emva kokuqhubeka nokusika uvavanyo, kwafunyaniswa ukuba kukho iipatches kwindawo ephantsi yommese we-stent (Umfanekiso 2).Emva kokulungelelanisa ukuphakama kokusika kunye namandla e-laser kwakhona, ezininzi zeepatches zazingekho, kwaye kwakusekho inani elincinci leepatshi kwindawo enye (Umfanekiso 3).Emva kokulungiswa kakuhle kwamandla e-laser kwakhona, iipatches zanyamalala, kwaye i-stent ye-2.64mm ye-diameter yasikwa ngempumelelo ngokugqibeleleyo.
Okwangoku, i-nickel-titanium stent iye yaveliswa ngobuninzi ukubonelela ngeenkonzo ezikumgangatho ophezulu kubasebenzisi abaninzi abanezifo zentliziyo.Njengomboneleli wenkonzo yezixhobo ze-laser yonyango echanekileyo, siya kudibanisa imfuno yemarike, siqhubeke nokushwankathela amava emveliso, kwaye siphuhlise ubukrelekrele, obusebenzayo, obuchanekileyo obuphezulu be-cardiovascular stent micromachining izixhobo kunye nezisombululo ezigqibeleleyo zetekhnoloji yokusika i-stent.
