Cardiac stents, tseem hu ua coronary stents, ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa cov hlab ntsha arteries, daws cov ntshav nruj, thiab ua kom cov ntshav du. Cov cuab yeej kho mob no tsuas yog siv nyob rau hauv kev kho mob coronary syndromes xws li mob myocardial infarction thiab yog ib qho cuab yeej muaj txiaj ntsig rau txuag lub neej.
Nrog kev nce qib nro ntawm kev kho mob technology thiab tom qab kev tshawb fawb thiab kev tshawb fawb ntau dua, cov khoom siv uas feem ntau, cov khoom siv feem ntau yog Titanium Alloy. Titanium alloy tsis tsuas muaj lub zog siab thiab corrosion tsis kam, tab sis kuj muaj qhov kev xaiv zoo tshaj plaws rau cov plawv stents.
Cov txheej txheem ntawm kev ua titanium lub plawv stents yog qhov muag heev. Nyob ntawm kev xav tau kev kho mob, lub cev ntawm stent yog qhov tseeb "carved". Tus stent yog tsim los txhawb cov hlab ntsha tsis muab tso rau ntau dhau ntawm cov ntaub so ntswg ib puag ncig.
Khwv yees tias ntau dua 10 lab titanium cardiac stenting cov txheej txheem tau ua thoob ntiaj teb. Tus lej no qhia tsis tsuas yog siv cov kev siv titanium cardtaws titanium.
Thaum lub sij hawm zais pa dolonary dilatation, ib-daim phiaj titanium cardiac stent yog txuas rau lub zais pa. Thaum lub zais pa tau dilated, tus stent qhib thiab ruaj khov rau cov leeg nqaim. Qhov no yog lub ntsiab cai ntawm intracoronary stenting.
Tam sim no, cov stockiac tau muab tso rau hauv kwv yees li 80% ntawm tag nrho cov kev tiv thaiv kab sib haum. Cov stents no tsis tsuas yog ua tau zoo hauv kev hloov siab cov neeg mob cov tsos mob tshwm sim, tab sis kuj txhim kho lawv lub neej zoo. Suav tsis muaj siab ntseeg tau txais kev cawmdim ua tsaug rau kev siv zoo kawg li ntawm titanium hauv cardiac stents.
