Nitinol yog ib qho tshwj xeeb hlau alloy muaj ntau ntawm ob lub ntsiab, npib tsib xee (ni) thiab titanium (ti). Nws lub npe "Nitinol" yog kev sib xyaw ua ke thiab nws qhov chaw ntawm kev nrhiav pom, cov chaw ua lag luam ntawm Naval Organ, Tebchaws Asmeskas (Ni-Ti-NOL).
Ni-Ti-NOL muaj ob qho khoom zoo kawg nkaus: cov qauv nco thiab superelasticity. Cov khoom no ua rau nws muaj txiaj ntsig nyob rau hauv cov ntawv thov engineering thiab kev kho mob.
Superelasticity: Nitinol muaj superelasticity, tso cai rov qab mus rau nws cov qauv qub txawm tias tom qab muaj kev tiv thaiv loj. Qhov no ua rau nws muaj txiaj ntsig hauv kev tsim cov khoom siv kho mob thiab cov kev cog lus uas yuav tsum tau tiv thaiv lawv cov qauv qub, xws li cov stents thiab kev cog hniav.
Cov duab nco txog: Nitinol muaj cov qauv zoo li qub, uas txhais tau tias nws tuaj yeem cim tau thiab rov txiav txim siab ua ntej cov qauv ntsuas kub. Qhov no tso cai rau nws yoog rau qhov sib txawv thiab cov duab nyob hauv lub cev thiab yog siv hauv kev tsim cov khoom siv kho mob thiab cov pob txha uas xav tau, kev cog hniav, cov kaus mom.
Biocompatibility: Nitinol muaj cov biocompatibility zoo heev thiab yog sib xws nrog tib neeg cov ntaub so ntswg tsis ua rau tsis muaj kev tsis haum lossis kev ua xua. Qhov no ua rau nws muaj kev nyab xeeb rau siv rau hauv kev tsim cov khoom siv ntawm kev cog hniav thiab cov khoom siv kho mob, xws li kev cog lus siv, stents thiab moreters.
Corrosion Kuj (corrosion tsis kam): nitinol muaj cov khoom zoo corrosion tsis kam thiab muaj peev xwm muaj nyob hauv lub cev ntev uas tsis tau ua rau lub cev ua kua lossis cov ntaub so ntswg. Qhov no tso cai rau nws siv rau hauv kev tsim cov khoom siv kev cog hniav thiab cov khoom siv kho mob xws li cov plhaw cardiac, orthopedic kev cog lus, thiab lwm yam.
Lub zog siab thiab lub zog: nitinol yog lub zog siab thiab lub teeb yuag thiab muab cov khoom siv uas muaj peev xwm ua tau zoo thaum ua kom muaj zog thiab cov khoom siv hluav taws xob txaus. Qhov no ua rau nws muaj txiaj ntsig zoo hauv kev tsim cov khoom siv kho mob thiab cov neeg uas xav tau ob lub zog thiab lub teeb yuag.
Cov khoom ntawm nitinol ua rau nws dav siv nyob rau hauv kev kho mob teb los tsim cov stents, kev cog qoob loo, riam phom thiab lwm yam khoom siv kho mob. Nws tseem siv nyob rau hauv ntau hom kev thov engineering xws li aerospace, kho tsheb, thiab cov khoom siv tshwj xeeb xws li cov ntaub ntawv kub thiab cov ntaub ntawv ntse.
Cov hauv qab no yog cov lus piav qhia luv luv ntawm cov ntaub ntawv thov hauv kev kho mob
I. Cardiovascular
Cov stents: cov neeg tsis sib haum yog cov qauv hlau mesh siv los nthuav dav thiab txhawb cov hlab ntshav. Nitinol alloys, vim lawv lub superelasticity thiab cov qauv nco tau, cia li rov qab mus rau nws tus thawj ntawm cov nkoj uas txhawb nqa lub nkoj uas txhawb nqa.
o Guiders thiab tus kheej: nyob rau hauv cov txheej txheem kev cuam tshuam, cov kws kho mob thiab tus kws kho mob tau siv los coj thiab ua haujlwm lwm cov khoom siv xws li stents thiab cov zais pa. Lub superelasticity thiab cov cim nco ntawm nitinol alloys tso cai rau cov pob hluav taws thiab cov tau qhia tawm hauv cov hlab ntshav thiab rov qab mus rau lawv cov duab ua ntej thaum xav tau.
o ThrombectSomy pab kiag li lawm: Cov khoom siv no tau siv los tshem tawm cov ntshav txhaws los ntawm cov hlab ntshav. Lub superelasticity thiab cov cim xeeb ntawm cov khoom siv nitinol tso cai rau cov hlab ntshav uas cuam tshuam los ntawm cov hlab ntshav, yog li tshem cov ntshav txhaws ntau dua.
o Lub plawv li qub: qee lub plawv lub plawv yog ua los ntawm nitinol los txhawb thiab txhim kho valve muaj nuj nqi. Cov roj no tuaj yeem yog cog los ntawm cov txheej txheem kev ua haujlwm los kho cov kab mob plawv plawv.
o AneurysM Kho: Nitinol alloys tseem siv nyob rau hauv kev kho ntawm aneurysms (hauv zos o o o off ntawm lub nkoj phab ntsa). Stents thiab lwm yam duab cov khoom siv cim xeeb tuaj yeem siv los txhawb thiab kho cov ntshav hluav taws.
Ii. Cov ntsha ntawm cov ntsha
o Lub sijhawm ua ntu zus los: zoo ib yam li cov tawv nqaij daim tawv, xws li cov hlab ntsha sab nrauv, xws li cov hlab ntsha sab nrauv hauv ob txhais ceg. Lub superelasticity thiab cov duab nco kev cuam tshuam ntawm nitinol stents tso cai rau lawv kom yoog cov duab ntawm cov hlab ntshav thiab khaws nws qhib.
o Aneurysm kho: kho cov pob zeb aneeurysms, xws li plab tsw phem, feem ntau yuav tsum siv cov stents lossis lwm cov khoom siv los txhawb thiab kho cov ntshav sab nraud. Nitinol stents tuaj yeem muab cov kev txhawb nqa uas xav tau thiab pab tiv thaiv kev sib tawg ntawm aneurysm.
o Guiders thiab tus kheej: nyob rau hauv cov kev cuam tshuam ntev kawg, cov kws kho hluav taws xob thiab cov kws kho mob tau siv los coj thiab txoj haujlwm lwm cov khoom siv xws li cov zais pa lossis stents. Lub superelasticity thiab cov duab nco cov kev cuam tshuam ntawm nitinol tso cai rau tus kheej thiab ua rau pom kev ua nqaim thiab virtusel.
o Qhov kev kho ntshav ntws dav hlau occlusalcusion: cov khoom siv xws li Nitinol stents thiab cov zais pa me me tau siv los kho cov ntshav hlab ntsha thiab pab rov qab cov ntshav ntws.
Cov txheej txheem kev cuam tshuam kev cuam tshuam: Hauv kev ntsuas cov txheej txheem ua ntej, lub cim xeeb nco thiab txoj kev kho kom yooj yim los tshem tawm cov quav hniav lossis ntshav khov ntawm cov leeg ntshav.
III. Cerospovascular
o Cerebral Aneurysm Kho (Cerebral Aneurysm Kho): Cerebral Aneurysm yog qhov kev phom sij ntawm kev ua kom ntshav uas tuaj yeem ua rau los ntshav lossis tawg. Nitinol stents thiab kauv cov cuab yeej siv tau siv rau kev kho cerebral aneurysm kho. Cov khoom siv no tuaj yeem tso los ntawm cov hlab ntshav thiab xa tawm hauv lub nkoj labysm los txhawb lub nkoj ntawm phab ntsa thiab txo qis kev pheej hmoo ntawm aneurysm txuas ntxiv mus nthuav dav.
o Kev kho mob los ntawm kev mob plab hnyuv: Cerebral Arterial Stenosis tuaj yeem ua rau muaj mob txaus ntshai xws li ischemic stroke. Cov cuab yeej siv xws li nitinol stents thiab cov dilators tuaj yeem siv los kho cov hlab ntsha senosis los ntawm kev ua kom cov ntshav tawm.
o Aneurysym embolization: Qhov no yog ib qho txheej txheem kev ua haujlwm siv los thaiv cov ntshav ntws mus rau lub hlwb aneurysm thiab txo qhov kev pheej hmoo ntawm kev sib tawg. Lub superelasticity ntawm nitinol alloy tso cai rau cov khoom siv uas tsis muaj zog los sau cov aneurysm thiab tiv thaiv ntshav nkag mus rau nws.
o Angioplasty: Nitinol zais cov dilators yog siv nyob rau hauv Cerebral angioplasty los txhim kho cov ntshav ntws los ntawm kev ua kom cov ntshav nqaim.
O endovasco aneurysm kev kho: Qhov txheej txheem kev tiv thaiv no tau siv txoj kev catheter thiab nitinol stent los kho cerebral aneeurysms.
IV. Electrophysiology
