1. Kev Txheeb Xyuas Txog Kev Kho Mob Qib Nitinol
Nitinol yog ib qho hlau ua haujlwm uas muaj nickel thiab titanium nyob rau hauv qhov sib piv ze-equiatomic, thiab nws yog cov hlau nco qab siv dav tshaj plaws hauv kev kho mob. Nws ua ke cov nyhuv nco qab zoo li qub, superelasticity thiab biocompatibility zoo heev, tawg los ntawm cov kev txwv kev ua tau zoo ntawm cov khoom siv hlau ib txwm muaj thiab ua haujlwm ua cov khoom siv tseem ceeb rau kev kho mob tsawg kawg nkaus thiab cov khoom siv kho mob cog rau hauv.
Cov khoom xyaw tseem ceeb thiab cov haujlwm ntawm cov txheej txheem kho mob nitinol tau qhia hauv lub rooj hauv qab no:
| Cov Ntsiab Lus Tseem Ceeb | Cov Ntsiab Lus Ntau Yam | Lub Luag Haujlwm Tseem Ceeb |
| Nickel (Ni) | ~55 ntawm% | Tswj qhov kub thiab txias ntawm theem hloov pauv thiab ua rau lub cim xeeb zoo li cas thiab cov khoom superelastic |
| Titanium (Ti) | ~45 ntawm% | Tsim kom muaj lub hauv paus biocompatibility thiab corrosion resistance ntawm cov khoom siv |
| Cov ntsiab lus tsis muaj teeb meem (C, N, O, thiab lwm yam) | Cov nqi raws li qhov ntsuas | Ua kom zoo dua cov khoom siv kho tshuab thiab kev hloov pauv theem |
4. Kev Sib Piv Kev Ua Haujlwm Nrog Cov Hlau Kho Mob Ib Txwm Muaj
Rau kev siv thaum xaiv cov khoom siv, lub rooj hauv qab no piv rau nitinol nrog cov hlau kho mob tseem ceeb thoob plaws qhov tseem ceeb ntawm kev ua tau zoo:
| Hom Khoom Siv | Cov Khoom Siv Nco Txog Duab | Qib Kev Ywj Pheej | Kev sib haum xeeb ntawm lub cev | Kev Tiv Thaiv Kev Qaug Zog | Tus Nqi Txoj Haujlwm | Cov Ntawv Thov Kho Mob Tseem Ceeb |
| Nitinol Qib Kho Mob | Yog (tuaj yeem tswj tau qhov kub thiab txias) | Siab heev (superelastic) | Zoo heev | Zoo heev | Nruab nrab mus rau siab | Cov stents uas tsis tshua muaj kev cuam tshuam, cov xov hlau qhia, thiab cov khoom cog rau hauv lub plawv |
| 316L Cov Hlau Stainless Hlau Kho Mob | No | Nruab Nrab | Zoo | Ncaj ncees | Kev Lag Luam | Kev kho pob txha caj qaum dav dav, cov cuab yeej phais txheem |
| Cobalt-Chromium Alloy | No | Nruab nrab-siab | Zoo | Zoo heev | Qib siab | Kev hloov pob qij txha, kev cog hniav |
| Kev Kho Mob Titanium Alloy | No | Nruab Nrab | Zoo heev | Zoo | Nruab nrab mus rau siab | Cov khoom cog rau pob txha, cov khoom cog rau hniav, cov khoom cog rau phais |
Kev sib piv luv luv:
Piv nrog cov hlau tsis xeb / titanium alloys: Nitinol muaj cov cim xeeb zoo nkauj thiab cov khoom superelastic, muab cov txiaj ntsig zoo tshaj plaws hauv kev cuam tshuam tsawg kawg nkaus thiab cov xwm txheej thauj khoom dynamic. Nws yog cov khoom siv tseem ceeb uas tsav tsheb phais mob tsawg kawg nkaus thiab txhim kho cov txiaj ntsig ntawm tus neeg mob.
Piv nrog cov hlau cobalt-chromium: Nitinol muaj qhov zoo tseem ceeb hauv kev muaj peev xwm hloov pauv elastic, ua rau nws tsim nyog dua rau cov khoom siv uas xav tau kev hloov pauv loj thiab kev ua raws li dynamic, nrog rau kev sib piv biocompatibility thiab ntau yam kev siv.
5. Cov yam ntxwv ntawmTankii Cov Khoom Siv Kho Mob Nitinol
Tankii muab cov khoom siv hlau nitinol kho mob qib siab, tsim tawm raws li cov qauv tsim khoom siv kho mob thiab hloov kho rau cov kev xav tau ntawm ntau yam khoom siv kho mob:
Kub hloov pauv theem uas tswj tau zoo: Qhov kub ntawm austenite tiav (Af) tuaj yeem ntsuas tau raws li qhov yuav tsum tau tsim khoom siv, hloov kho rau ntau yam xwm txheej siv xws li kev ua kom lub cev kub thiab chav sov superelasticity.
Kev ua tau zoo sib xwsKev tswj hwm nruj rau qhov kam rau ntawm txoj kab uas hla thiab qhov zoo ntawm qhov chaw. Txhua pawg tau dhau los ntawm kev sim cov khoom sib xyaw, kev txheeb xyuas qhov kub hloov pauv theem thiab kev txheeb xyuas cov khoom siv kho tshuab kom ntseeg tau tias cov khoom ua haujlwm ruaj khov thiab sib xws.
Kev them nqi tag nrho: Npog tag nrho cov loj me los ntawm 0.02 hli ultra-fine hlau mus rau kev lag luam hnyav-gauge hlau, muaj nyob rau hauv ntau hom kev xa khoom xws li hlau ncaj thiab hlau kauj, hloov kho rau cov txheej txheem tsim khoom sib txawv.
Kev lees paub txog kev ua raws li txoj cai: Cov khoom siv raw muaj kev huv si thiab tswj tau qhov tsis huv kom zoo. Cov ntawv pov thawj thiab cov ntawv qhia kev xeem tuaj yeem muab tau los ua kom tau raws li kev cai thiab kev cai lij choj ntawm kev tsim khoom siv kho mob.
6. Cov Kev Xav Tseem Ceeb rau Kev Xaiv Khoom Siv
l Nrog nws peb lub zog tseem ceeb -cov nyhuv cim xeeb zoo li cas, superelasticity thiab biocompatibility siab — nitinol tau dhau los ua cov khoom siv ua haujlwm zoo tshaj plaws rau cov khoom siv kho mob tsawg kawg nkaus thiab cov khoom siv cog rau hauv, ua lub hauv paus tseem ceeb rau kev txhim kho cov thev naus laus zis kho mob tsawg kawg nkaus.
