Umukiriya wumuhinde nikel-titanium stent sample yo guca ibintu

Umuhindeimashini ikata mikorobeyarangiye nyuma yo kugurisha, umusaruro wa stent ubusanzwe wakozwe, ibikoresho bigenda neza, kandi stent nshya yibikoresho bigiye gutegurwa kubyara umusaruro, ariko mu buryo butunguranye yohereza icyifuzo cya tekiniki.Ikibazo kirihe, ngwino urebe uwabikoze abagabo-amahirwe nuburyo bwo gukurikirana.

Umukiriya amaze gusimbuza nikel-titanium stent tube, habaye ikibazo mugukemura ibikoresho.Tugomba gufasha muburyo bwo gukemura ibibazo dukurikije ibishushanyo bya stent byatanzwe nabakiriya kugirango tumenye neza ko inkunga nshya ishobora kugabanywa bisanzwe.Ba injeniyeri bacu basuzumye neza igishushanyo basanga igishushanyo kituzuye, nuko bahindura igishushanyo.Bitewe no gusimbuza ibikoresho bibisi byumuyoboro, amakuru ya diameter ntabwo arimwe, bushing na chuck kubikoresho byimashini zikata laser bigomba gusimburwa, uburebure bwo gutema nabwo bugomba kongera gucukurwa, nyuma ya kure ya kure ya kure yibanze hamwe ningufu za laser gukemura, gukata mubyukuri bigomba kuba bisanzwe.

Ariko, ikibazo gishya cyabaye mugikorwa cyo guca ibizamini, ibikoresho fatizo ntibishobora gucibwa burundu.Nyuma yo gupima neza no kugereranya n'ibishushanyo, injeniyeri yasanze ubugari bwa diameter yubufasha bwari 0.04mm buto kurenza ubunini nyabwo.Ubugari bwa diameter bwatanzwe nabakiriya bwari 2,6mm, ariko ubunini nyabwo bwari 2,64mm (Ishusho 1 yinkunga), bityo umuyoboro ntushobora gucibwa mubisanzwe, kandi nikosa 0.04 naryo ryagaragaye nibikoresho.Nyuma yamakuru ya diameter amaze guhindurwa, ikibazo cyo guca nikel-titanium stent kirakemuka byoroshye.

Nyuma yo gukomeza gukata ibizamini, byagaragaye ko hari uduce twinshi ku cyuma cyo hasi cya stent (Ishusho 2).Nyuma yo guhindura uburebure bwo gukata hamwe ningufu za lazeri, ibyinshi byarashize, kandi haracyariho uduce duto duto ahantu hamwe (Ishusho 3).Nyuma yo gutunganya neza ingufu za laser, ibishishwa byarazimanganye, kandi stent ya diametero 2,64mm yaciwe neza.
