Qhov tseem ceeb ntawm Lub Koob Ntog: Txoj Kev Ncauj Ncauj Los Ntawm Cov Hlau Tseem Ceeb Rau Bio-Inertness

Nto Engineering & Ua Raws Li Kev Pom Zoo|Qhov tseem ceeb ntawm rab koob nto: Txoj Kev Ncauj Ncauj Lus los ntawm "Metallic Original Sin" mus rau "Bio-Inertness"

Nyob rau hauv lub ntiaj teb siab -kawg cov khoom siv kho mob, qhov kawg tus nqi ntawm VABB koob nyob ntawm tsis yog tsuas yog nyob rau ntawm lub ntse ntse ntawm nws lub ntsis tab sis kuj nyob rau ntawm "purity noob" nws nqa tom qab tu, passivation, thiab polishing. Qhov no yog qhov kawg mais ntawm cov hlau tsis huv mus rau cov khoom tsis muaj menyuam ua tiav, sawv cev rau qhov chaw uas cov kev cai kho mob thiab kev lag luam tu thev naus laus zis sib tsoo feem ntau.

I. Passivation: Lub Invisible "Anti-Corrosion Armor"

Cov ntawv nyeem qhia txog qhov xav tau ntawm lub cev koob kom tau txais kev kho mob passivation ntawm immersion nyob rau hauv ib tug citric acid tov.

Electrochemical Kho:Txawm hais tias stainless hlau passivates spontaneously nyob rau hauv cov huab cua, nws nto feem ntau khaws dawb hlau ions thiab ua ferrous khib nyiab. Qhov tseem ceeb ntawm citric acid passivation nyob rau hauv nws cov tshuaj tiv thaiv uas "siv" cov impurities, txhawb cov enrichment ntawm chromium ntsiab nyob rau saum npoo los tsim ib tug heev ntom chromium oxide (Cr₂O₃) passive zaj duab xis tsuas yog ob peb nanometers tuab.

Muaj nuj nqis:Qhov tseem ceeb ntawm zaj duab xis no yog tias nws thaiv txoj kev leaching ntawm cov hlau ions rau hauv tib neeg cov ntaub so ntswg, tiv thaiv kev mob qeeb lossis kev tsis haum tshuaj los ntawm cov khoom siv corrosion. Nws yog ib qho tseem ceeb ua ntej yuav tsum xeem dhau ISO 10993 biocompatibility tests.

II. Electropolishing: Ib Nanoscale "Daim iav Revolution"

Lub cev tseem ceeb ntawm Micro-Leveling:Cov txheej txheem electropolishing yog qhov tseem ceeb ntawm atomic -theem "ncej shaving thiab hav filling" ntawm cov hlau nto. Los ntawm kev tshem tawm cov kab mob microscopic thiab lis ciam teb protrusions, nws txo qhov roughness ntawm micron mus rau qib nanometer.

Anti-Fuling thiab Anti-Coagulation Interface Effects:Lub ultra- du nto ua rau txo qis "cov ntsiab lus thauj tog rau nkoj" rau protein adsorption thiab platelet adhesion. Clinically, qhov no tsis yog tsuas yog txo qis kev pheej hmoo ntawm kev ua haujlwm tom qab- kis kab mob tab sis tseem tiv thaiv cov ntshav coagulation thiab txhaws nyob rau hauv cov koob lumen, kom ntseeg tau qhov smoothness ntawm cov txheej txheem biopsy.

III. Ultrasonic Tu: Lub "Cavitation Kev Cai Raus Dej"

20-40kHz Lub cev ntxuav:Kev siv siab - zaus ultrasound los tsim cov npuas microscopic hauv cov tshuaj ntxuav, qhov tseem ceeb ntawm micro- dav hlau tsim thaum npuas tawg yog lawv lub peev xwm los tshem tawm cov tsis pom micron - cov hlau tawg thiab cov khoom siv tshuaj txhuam cov khoom seem hauv lub koob raj. Qhov no yog qhov tseem ceeb rau kev tiv thaiv kev tshaj tawm - cov tshuaj tiv thaiv pyrogenic (ua npaws los ntawm cov kab mob sib kis).

IV. RoHS thiab Lub Luag Haujlwm ntawm Green Manufacturing

Cov ntawv nyeem tshwj xeeb hais txog kev ua raws li RoHS Cov Lus Qhia (2011/65 / EU thiab nws cov kev hloov kho).

Ecological tseem ceeb ntawm kev ua raws cai:Qhov no txhais tau hais tias kev tswj hwm nruj ntawm cov ntsiab lus ntawm cov khoom phom sij xws li txhuas, cadmium, thiab mercury thaum lub sijhawm tsim khoom. Rau cov cuab yeej kho mob uas tuaj yeem cog tau, qhov no tsis yog kev cog lus rau cov neeg mob kev noj qab haus huv nkaus xwb tab sis kuj yog "passport" rau kev ua txhaum kev lag luam thoob ntiaj teb kev lag luam ntsuab thiab nkag mus rau qib siab - kev tswj hwm - kev lag luam zoo li EU.

Xaus:

Los ntawm qhov kev xav ntawm kev ua raws li kev lag luam thiab kev tsim vaj tsev, qhov "purification tseem ceeb" ntawm VABB koob nto yog qhov tseem ceeb rau nws lub meej mom raws li Class III cov cuab yeej kho mob. Nws ua pov thawj tias rab koob no tsis yog ib qho ntawm cov hlau zoo nkaus xwb, tab sis yog ib qho kev lag luam kos duab uas tau dhau los ua ib txhiab kev kho kom tau raws li lub ntiaj teb cov qauv siab tshaj plaws ntawm kev nyiam huv thiab kev nyab xeeb.
