Yuav ua li cas tuaj yeem hlau 3D luam ntawv txhawb kev customized lub siab stent ntau lawm?

1. Kev tawg hauv thev naus laus zis rau 3D luam tawm hlau yog rov kho dua lub bracket ntau lawm paradigm.
Kev hloov pauv ntawm cov qauv tsim qauv
Thaum hlau 3D luam tawm tsim ib qho kev sib tw peb-seem raws li cov neeg ua haujlwm ntawm cov neeg mob CT lossis MRI, yog li ntawd tau "stent-stent tsim cov ntaub ntawv. Siv BIFurcation qhov txhab ua piv txwv, cov stents ib txwm muaj feem ntau yuav tsum tau studacing ntau stents, uas tuaj yeem tsim kev puas tsuaj rau cov hlab ntsha; 3D luam tawm tuaj yeem tsim ib qho y-puab stent, txhim kho kom haum nrog cov hlab ntsha los ntawm 60%. Customized stents Tsa txoj kev phais kom zoo los ntawm 35%, raws li kev kawm ua tiav los ntawm Berlin Heart Center hauv Tebchaws Yelemees.
Qhov tseeb thov ntawm cov nruab nrab
Hlau 3D Luam Ntawv Txhawb cov qauv tsim qauv zoo li Gradient Porosity thiab Tshuaj Kho Cov Tshuaj Siv Microorroaig. Xav txog:
Gradient Porosity yog: hos sab hauv txheej ntawm cov leeg me me (200 μ μm) txhawb nqa cov loj loj (500 μ μm) txhawb nqa cov xov tooj ntawm cov xov tooj endothelial.
Tshuaj Nrog Yeeb Tshuaj: Cov qauv microornoveove kev tswj hwm cov tshuaj tso tawm Yeeb Tshuaj kom ua tiav kev nce qib ntawm vascular proliferation. Hauv Tebchaws Meskas Qhov Kev Kuaj Xyuas Kev Tshawb Xyuas, cov qauv no txo ​​qis sib luag thrombosis muaj qhov cuam tshuam los ntawm 55%.
Cov Sijhawm Tsis Muaj Los Ntawm Cov Khoom Siv Muaj Peev Xwm
Stent ntawm biodegradable cov ntaub ntawv: ua los ntawm cov magnesium-raws li cov alloy, lig tawg hauv rau kaum ob lub hlis los tiv thaiv cov khoom ntev ntawm cov khoom txawv.
Los ntawm kev hloov kho deg nrog titanium alloy, nws stimulates endothelial cell proliferation thiab hastens vascular mob.
2. Kev kuaj mob tus nqi: Kev kuaj-rau-ua haujlwm lub rooj nrog cov ntaub ntawv
Qhov tseeb qauv ntawm cov tshuaj kho mob
Hauv cov xwm txheej nyuaj, muaj kev sib tawg hauv kev nyuaj tau tshwm sim: 3D-luam tawm cov txheej txheem hauv kev npaj rau cov kab mob ntshav thiab muab cov ntshav ntshav, ua kom pom tseeb. Piv rau 82% ntawm cov kev sib tw sib xyaw, kev tshawb fawb hauv Netherlands tau qhia tias kev ua tiav ntawm kev ua tiav ntawm kev ua raws li kev tswj hwm tau yog 98%, kom siab dua.
Lub sijhawm ntev ua haujlwm nce: Cov hlab ntsha stentels 'synchronized pulse ua tau los ntawm gradient pore kev tsim qauv pab txo cov kev nkees nkees. Tus nqi ntawm lub hom phiaj rov qab rau cov stents customized tsuas yog 12%, raws li cov ntaub ntawv rov qab raws sijhawm.
Ib qho kev tsim kho tau zoo
Thaum hlau 3D luam tawm txiav lub voj voog txiav mus rau 72 teev, kev sib tw sib tw ua ib txwm siv sijhawm li 4-6 lis piam. Nrog rau kev siv cov khoom siv ntawm 95%, lub m {5}} luam ntawv customization tsim thiab tuaj yeem siv 10 qhov kev tsim qauv hauv ib pob.
