Ti-6Al-4V ELI titanium alloy plawv stent

Hauv kev kho cov kab mob plawv, lub plawv stents tau suav tias yog ib qho txuj ci tseem ceeb ntawm cov tshuaj niaj hnub no. Thaum cov hlab ntsha ntawm cov hlab ntsha nqaim lossis txawm tias raug thaiv vim yog cov quav hniav, cov hlau mesh no tsuas yog ob peb millimeters ntawm txoj kab uas hla, tuaj yeem ncav cuag qhov mob los ntawm kev phais me me, ua haujlwm zoo li lub kaus me me 'lub neej' kom qhib cov hlab ntsha thiab tso cov ntshav ntws, uas yog nyob rau ntawm verge ntawm stagnation dua. Dab tsi muab qhov txuj ci kho mob no nws qhov kev ua tau zoo tseem ceeb yog cov khoom siv titanium alloy, qhuas tias yog 'biometal.'

Ti-6Al-4V ELI titanium alloy cardiac stent kuj yog ib hom Ti-6Al-4V titanium alloy khoom, kuj hu ua ultra-low interstitial element titanium alloy. Tam sim no nws yog titanium alloy nquag siv hauv kev kho mob.

Qib ELI (Ntxiv Qis Interstitial): yog hais txog cov ntsiab lus tsawg heev ntawm cov khoom sib txawv (xws li oxygen, nitrogen, hlau). Qhov no ua rau txhim kho pob txha toughness thiab ductility ntawm cov khoom, txo cov kev pheej hmoo ntawm qaug zog tawg nyob rau hauv ntev - lub sij hawm cyclic loads, uas yog ib qho tseem ceeb rau cog - theem kev ntseeg tau. Lub billet yuav tsum tau precision machined kom ua tiav qhov siab qhov tseeb, phab ntsa thickness uniformity, thiab sab hauv nto tiav.
 

Ti-6Al-4V ELI titanium alloy cardiac stents yuav tsum ua tiav micron- theem txiav precision, nrog kev txiav kom huv si, tsawg kawg ntawm tshav kub-tshem tawm tsam, thiab txo qhov siab tshaj plaws ntawm kev puas tsuaj rau cov khoom siv. Polishing: Nws yog ib qho tsim nyog yuav tsum tau ua kom huv si tshem tawm slag thiab micro-burrs tsim thaum lub sij hawm txiav, raws li tej yam me me tsis xws luag yuav dhau los ua qhov pib taw tes ntawm qaug zog tawg. Rau kev kho cua sov ntawm Ti-6Al-4V ELI titanium alloy cardiac stents, lub tshuab nqus tsev annealing feem ntau yog ua los tshem tawm cov kev ntxhov siab, ua kom lub microstructure ruaj khov, thiab tau txais cov khoom sib npaug.

Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm
Ntxuav Ti-6Al-4V ELI titanium alloy cardiac stents yuav tsum tau nqa tawm hauv chav huv, siv cov dej ntshiab huv thiab cov kuab tshuaj kom ntseeg tau tias tshem tawm tag nrho cov khoom seem, cov khoom, thiab cov pyrogens. Kev tshuaj xyuas muaj xws li kev ntsuas qhov ntev hauv lub tshuab ntsuas, ntsuas radial crush resistance tests, kev sim qaug zog simulating lab lub plawv dhia, thiab qhov tseem ceeb tshaj plaws, kuaj biocompatibility (cytotoxicity, rhiab heev, thiab lwm yam).

Kev ntsuas los xyuas kom meej qhov kev ruaj ntseg ntawm Ti-6Al-4V ELI titanium alloy cardiac stents suav nrog: kev ua haujlwm nyob rau hauv qhov kub thiab txias ib puag ncig thoob plaws; ua qhov kev tshuaj ntsuam xyuas qhov muag/electron microscopy tom qab txhua txoj kev los saib xyuas qhov sib xws ntawm lub sijhawm; thiab kuaj cov khoom kawg nyob rau hauv simulated compression thiab expansion tej yam kev mob los xyuas kom meej lawv raug rov qab mus rau lub tsim qauv tom qab tso tawm ntawm lub catheter.

Txawm hais tias Ti-6Al-4V ELI titanium alloy lub plawv stents qhia tau tias muaj kev ruaj ntseg, lub zej zog kho mob yeej ib txwm tau ceev faj tus cwj pwm ntawm qhov muaj peev xwm lom lom lom ntawm vanadium (V) cov khoom uas lawv muaj. Yog li ntawd, cov kws tshawb fawb tau maj mam tsim cov ntaub ntawv zoo dua qub, xws li Ti-6Al-7Nb titanium alloy uas vanadium hloov los ntawm niobium (Nb). Qhov tshiab titanium alloy no ho txhim kho biocompatibility thaum tuav lub zog zoo txhua yam thiab maj mam nkag mus rau hauv daim ntawv thov kho mob.
