Daim ntawv thov ntawm titanium-nickel alloy nco hlau hauv tshuaj
Cov ntsiab lus
Titanium-nickel alloy nco hlau yog ib qho tshwj xeeb alloy nrog cov duab cim xeeb. Nws yog dav siv nyob rau hauv kev kho mob teb thiab muab tshiab possibilities rau ntau yam kev kho mob pab kiag li lawm thiab txoj kev kho mob. Nws cov duab cim xeeb tso cai rau nws rov qab kho nws cov duab qub nyob rau hauv qee yam mob, thiab nws cov ntawv kho mob koom nrog ntau thaj chaw.
Qhia
Titanium-nickel alloy, tseem hu ua "superelastic alloy" lossis "zoo li nco alloy", yog tsim los ntawm ob hlau: titanium thiab npib tsib xee. Nws tau pom thawj zaug los ntawm Naval Ordnance Laboratory hauv Tebchaws Meskas thaum xyoo 1960s, thiab tau siv dav hauv kev kho mob. Cov duab cim xeeb ntawm titanium-nickel alloys qia los ntawm cov theem hloov pauv ntawm nws cov qauv siv lead ua, uas tso cai rau nws rov qab mus rau nws cov duab qub tom qab raug rau sab nraud stimuli.
1. Stents thiab implants
Vascular stents: Titanium-nickel alloy nco hlau feem ntau yog siv los ua vascular stents los kho arterial stenosis lossis occlusion. Lub stent tuaj yeem cog rau hauv cov hlab ntsha hauv lub cev thiab tom qab ntawd nthuav dav rau hauv cov qauv tsim siv cua sov lossis lwm txoj hauv kev los nthuav cov hlab ntsha nqaim. Vim lub superelasticity thiab cov duab cim xeeb ntawm titanium-nickel alloy, lub stent tuaj yeem rov qab mus rau nws cov duab qub tom qab muaj kev deformation, ua kom cov hlab ntsha smoothness.
Orthopedic implants: Hauv kev phais orthopedic, titanium-nickel alloy nco hlau yog siv los ua cov pob txha xws li pob txha daim hlau thiab cov ntsia hlau. Cov implants no tuaj yeem ua tau zoo li qhov xav tau thaum lub sijhawm phais kom zoo dua rau tus neeg mob cov pob txha. Thaum cog, lawv tuaj yeem rov qab mus rau lawv qhov kev xav tau los ntawm kev cuam tshuam ntawm lub cev kub lossis lwm yam stimulation, muab kev txhawb nqa ruaj khov thiab kho.
2. Kev kho mob plawv
Kev kho cov hlab ntsha zoo: Hauv kev kho plawv plawv, titanium-nickel alloy nco hlau tuaj yeem siv los tsim ntau yam khoom siv kho. Piv txwv li, los ntawm kev tso lub zais pa catheter nrog cov duab cim xeeb hauv cov hlab ntsha nqaim, cov hlab ntsha tuaj yeem ua rau hauv zos dilated thiab cov ntshav ntws tau zoo tuaj. Hom kev kho mob no yog qhov tseem ceeb hauv kev kho mob plawv xws li kab mob plawv.
kho lub plawv valve; Titanium-nickel alloy nco hlau kuj tuaj yeem siv los tsim kho lub plawv valve. Cov cuab yeej no tuaj yeem nkag mus rau hauv lub cev los ntawm cov hlab ntsha thiab tom qab ntawd nthuav dav rau lawv cov qauv qub raws li lub cev kub lossis lwm yam stimuli, kho lossis hloov lub plawv li qub thiab txhim kho lub plawv.
3. Neurosurgery
Kev kho mob hemangioma: Hauv kev phais mob neurosurgery, titanium-nickel alloy nco hlau tuaj yeem siv los tsim cov stents me me thiab cov lus qhia rau kev kho mob cerebral hemangioma. Cov stents tuaj yeem xa mus rau hauv cov qog los muab kev txhawb nqa thiab kho thaum muaj peev xwm hloov mus rau cov qauv ntawm lub hlwb.
Sib sib zog nqus hlwb stimulation: Titanium-nickel alloy kuj tseem siv tau rau hauv kev kho mob hlwb sib sib zog nqus. Los ntawm implanting electrodes ua los ntawm kev nco xaim, cov duab ntawm cov electrode tuaj yeem hloov kho hauv lub cev kom ntseeg tau tias nws tuaj yeem txheeb xyuas lub hom phiaj kho mob thiab txhim kho qhov tseeb ntawm kev kho mob.
4. Lwm daim ntawv thov kev kho mob
Kev ua kom cov leeg nqaij: Hauv cov tshuaj kho kom rov zoo, titanium-nickel alloy nco hlau kuj tuaj yeem siv los tsim cov khoom siv uas tuaj yeem pab cov neeg mob qhib lawv cov leeg. Cov cuab yeej no tuaj yeem kho lawv cov duab hauv kev teb rau kev txhawb nqa sab nraud, muab kev kho mob zoo.
Kev xa tshuaj: Lub superelasticity thiab cov duab cim xeeb ntawm lub cim xeeb xaim kuj tuaj yeem siv los tsim cov khoom xa tshuaj. Cov cuab yeej no tuaj yeem xa cov tshuaj mus rau lub hom phiaj cov ntaub so ntswg lossis cov kabmob hauv lub cev thaum tuav lub cev ruaj khov, kom ntseeg tau tias cov tshuaj tuaj yeem tso tawm kom raug qhov twg nws xav tau.
Cov ntsiab lus
Txawm hais tias titanium-nickel alloy nco xov hlau tau ua qhov kev vam meej hauv kev kho mob, qee qhov kev sib tw tseem muaj. Piv txwv li, qee cov neeg mob yuav ua xua rau cov npib tsib xee hauv cov hlau, uas yuav ua rau muaj kev tsis haum tshuaj. Tsis tas li ntawd, kev tshawb fawb tob ntxiv tseem xav tau ntawm kev ua haujlwm ntev ntev thiab biocompatibility ntawm lub cim xeeb hlau.
