Daim ntawv thov ntawm Nickel Titanium Alloy Hlau nyob rau hauv kev kho mob phais implants

Nickel titanium alloy hlau, raws li cov khoom siv nrog cov khoom tshwj xeeb, tau pom tias muaj peev xwm thiab muaj txiaj ntsig zoo hauv kev kho mob phais kev cog hniav. Nrog nws cov txiaj ntsig zoo nco, superelasticity, zoo biocompatibility, thiab corrosion kuj, npib tsib xee titanium alloy hlau tau dhau los ua cov khoom siv rau ntau yam kev kho mob thiab kev phais.

1. Daim ntawv thov ntawm cov duab nco zoo

Nickel titanium alloy hlau muaj lub cim xeeb zoo, uas txhais tau hais tias nws tuaj yeem nco qab thiab rov ua kom zoo dua qub ntawm qhov kub thiab txias. Cov yam ntxwv no ua rau nws muaj txiaj ntsig zoo hauv kev kho mob phais kev cog hniav:

1) Adaptability: Implants ua los ntawm npib tsib xee titanium alloy hlau tuaj yeem hloov mus rau cov qauv anatomical thiab physiological ib puag ncig ntawm tib neeg lub cev. Piv txwv li, vascular stents tuaj yeem hloov mus rau cov duab thiab qhov loj ntawm cov hlab ntsha tom qab implantation, muab kev txhawb nqa tas mus li thiab patency.

2) Qhov tseeb: Thaum lub sij hawm tsim cov txheej txheem, nickel titanium alloy xov hlau tuaj yeem raug teeb tsa ua ntej rau hauv cov duab tshwj xeeb, thiab tom qab ntawd rov qab mus rau qhov kev teeb tsa ua ntej los ntawm kev siv cua sov lossis lwm yam txhais tau tias thaum cog, kom ntseeg tau qhov tseeb thiab ruaj khov ntawm cov cog.

2. Kev siv ntawm hyperelasticity

Lub superelasticity ntawm npib tsib xee titanium alloy xaim hais txog nws lub peev xwm rov qab los rau nws cov duab qub tom qab tseem ceeb deformation. Qhov no feature ua rau nws haum rau cov kev siv hauv qab no hauv kev kho mob phais implants:

1) Elastic kev txhawb nqa: xws li lub plawv stents, stents ua los ntawm npib tsib xee titanium alloy hlau tuaj yeem raug compressed rau ib txoj kab uas hla me me thaum lub sij hawm ntxig thiab rov qab los rau lawv cov qauv qub thaum tso tawm, muab kev txhawb nqa elastic thiab ua kom cov hlab ntsha patency.

2) Kev qaug zog tsis kam: Super elasticity ua rau cov cog cog ua los ntawm cov nickel titanium alloy hlau tsis tshua muaj kev qaug zog thiab tawg thaum siv mus ntev, yog li txhim kho kev ntseeg tau thiab kev nyab xeeb ntawm kev cog qoob loo.

3. Daim ntawv thov ntawm biocompatibility thiab corrosion kuj

1) Biocompatibility: Nickel titanium alloy hlau muaj biocompatibility zoo thiab tuaj yeem sib haum nrog tib neeg cov ntaub so ntswg yam tsis ua rau muaj kev tsis txaus siab lossis kev tsis haum tshuaj. Qhov no ua rau cov implants ua los ntawm nws kom muaj kev nyab xeeb nyob rau hauv tib neeg lub cev mus ntev.

2) Corrosion kuj: Nickel titanium alloy hlau muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem nyob ruaj khov hauv lub cev ntev ntev yam tsis muaj corroded los ntawm lub cev los yog cov ntaub so ntswg. Qhov no feature ua kom lub sij hawm ntev stability thiab kev ruaj ntseg ntawm cov cog.

4. Cov xwm txheej tshwj xeeb ntawm daim ntawv thov

1) Cardiovascular stent: Cardiovascular stents ua los ntawm nickel titanium alloy hlau yog dav siv hauv kev kho mob vascular stenosis lossis occlusion. Lawv tuaj yeem hloov mus rau cov duab thiab qhov loj ntawm cov hlab ntsha, muab kev txhawb nqa tas mus li thiab patency, yog li txhim kho cov neeg mob lub neej zoo.

2) Orthopedic implants: Nickel titanium alloy hlau kuj yog siv los tsim orthopedic implants, xws li intramedullary rau tes, staples, thiab lwm yam. Cov implants no tuaj yeem hloov mus rau cov duab thiab qhov loj ntawm cov pob txha, muab kev ruaj ntseg zoo thiab kev txhawb nqa, txhawb kev puas tsuaj thiab kho dua tshiab.

3) Lwm yam kev cog qoob loo: Nickel titanium alloy hlau kuj tseem siv los tsim cov khoom siv phais mob xws li staplers thiab kho clips. Cov implants no ua lub luag haujlwm tseem ceeb hauv cov txheej txheem phais, txhim kho kev ua haujlwm thiab kev nyab xeeb ntawm cov txheej txheem.

Nickel titanium alloy hlau plays lub luag haujlwm tsis tuaj yeem hloov pauv hauv kev kho mob phais kev cog hniav vim nws cov khoom tshwj xeeb. Los ntawm cov hlab plawv stents mus rau orthopedic implants, los ntawm staplers los kho clips, nickel titanium alloy xov hlau muaj ntau yam kev siv, uas tsis tsuas yog txhim kho qhov kev vam meej ntawm kev phais thiab qhov zoo ntawm cov neeg mob kho, tab sis kuj txhaj tshuaj tshiab tseem ceeb rau kev kho mob. tshuab.
