UmNdiyaumshini wokusika we-lasersekuqediwe ngemva kokuthengiswa, ukukhiqizwa kwe-stent kuye kwenziwa ngokujwayelekile, okokusebenza kusebenza kahle, futhi i-stent entsha yezinto ezibonakalayo isizolungiselelwa ukukhiqizwa, kodwa kungazelelwe kuthunyelwe isicelo sokusekela lobuchwepheshe.Ikuphi inkinga, woza uzobona umenzi amadoda-inhlanhla indlela yokulandelela.
Ngemuva kokuthi ikhasimende lishintshe ishubhu le-nickel-titanium stent, kube nenkinga ekulungisweni kwemishini.Sidinga ukusiza ekulungiseni amapharamitha ngokuya ngemidwebo ye-stent enikezwe ikhasimende ukuze siqinisekise ukuthi ukwesekwa okusha kungasikwa ngokujwayelekile.Onjiniyela bethu bawuhlola ngokucophelela umdwebo futhi bathola ukuthi umdwebo wawungaphelele, ngakho bawudweba kabusha umdwebo.Ngenxa yokushintshwa kwezinto ezingavuthiwe zamapayipi, idatha yobubanzi ayifani, i-bushing kanye ne-chuck emshinini wokusika we-laser kufanele kushintshwe, ukuphakama kokusika nakho kudinga ukulungiswa kabusha, ngemuva kokude nokugxilwa kokugxila okukude okuthathu namandla e-laser. ukususa iphutha, ukusika ngokwethiyori kufanele kube okuvamile.
Kodwa-ke, inkinga entsha yenzeke ohlelweni lokusika ukuhlolwa, impahla eluhlaza ayikwazanga ukunqunywa ngokuphelele.Ngemva kokulinganisa ngokucophelela nokuqhathanisa nemidwebo, unjiniyela uthole ukuthi ububanzi bobubanzi bokusekela babungu-0.04mm buncane kunosayizi wangempela.Idatha yobubanzi bobubanzi obunikezwe ikhasimende bekungu-2.6mm, kodwa usayizi wangempela wawungu-2.64mm (Umfanekiso 1 wosekelo), ngakho ishubhu alikwazanga ukusikwa ngokujwayelekile, futhi iphutha elingu-0.04 liphinde latholwa yimishini.Ngemuva kokulungiswa kwedatha yobubanzi, inkinga yokusika i-nickel-titanium stent ixazululwa kalula.
Ngemva kokuqhubeka nokusika ukuhlolwa, kutholakale ukuthi kwakukhona ama-patches endaweni ephansi yommese we-stent (Umfanekiso 2).Ngemva kokulungisa ukuphakama kokusika namandla e-laser futhi, ama-patches amaningi ayengasekho, futhi kwakusenenani elincane lama-patches endaweni eyodwa (Umfanekiso 3).Ngemva kokulungisa kahle amandla e-laser futhi, ama-patches anyamalala, futhi i-stent engu-2.64mm ububanzi yasikwa ngempumelelo.
Njengamanje, i-nickel-titanium stent ikhiqizwe ngobuningi ukuze inikeze izinsizakalo zekhwalithi ephezulu kubasebenzisi abaningi abanezifo zenhliziyo nemithambo yegazi.Njengomhlinzeki wesevisi yemishini ye-laser micromachining enembayo yezokwelapha, sizohlanganisa isidingo semakethe, siqhubeke nokufingqa isipiliyoni sokukhiqiza, futhi sithuthukise imishini ye-cardiovascular stent micromachining ehlakaniphe kakhulu, esebenza kahle, enembayo ephezulu kanye nezixazululo zobuchwepheshe obuphelele zokusika i-stent.
