Thaum cov pob txha puas thiab cov kab mob sib koom ua ke nyuaj rau kho tau zoo, kev cog cov khoom siv kho mob ua qhov tseem ceeb rau kev kho mob. Ntawm ntau cov khoom siv implantable,titanium alloysawv tawm vim nws qhov kev ua tau zoo tshaj plaws thiab tau siv dav hauv cov pob qij txha, kev cog hniav, thiab lwm yam, ua tiav "kev sib haum xeeb" nrog tib neeg cov ntaub so ntswg. Tom qab qhov zoo kawg li "compatibility" yog ib qho kev sib koom ua ke ntawm cov ntaub ntawv science thiab biology.
Ib txwm Compatible: Lub Biocompatibility zais cia ntawm Titanium Alloys Titanium alloys tuaj yeem nyob sib haum xeeb nrog tib neeg lub cev, feem ntau yog vim peb qhov zoo ntawm qhov tseem ceeb. Lawv nto sai sai tsim cov titanium dioxide oxide zaj duab xis tuab. Qhov "invisible armor," tsuas yog ob peb nanometers mus rau kaum ntawm nanometers tuab, cais cov hlau matrix ntawm tib neeg cov ntaub so ntswg, tiv thaiv kev tso tawm ntawm cov hlau ions thiab zam kev tiv thaiv kab mob thiab o. Nws cov khoom siv tshuaj ruaj khov muab cov txiaj ntsig tseem ceeb rau kev cog qoob loo ntev -. Piv txwv li, tom qab kev cog qoob loo ntawm cov pob qij txha, cov oxide zaj duab xis no zoo tiv thaiv kev sib cuag ncaj qha ntawm cov ntaub so ntswg thiab cov hlau, txo qhov kev pheej hmoo ntawm kev kis kab mob.
Muab piv rau cov hlau tsis muaj steel thiab cobalt-chromium alloys, titanium alloys muaj qhov elastic modulus ze rau ntawm tib neeg cov pob txha. Lub elastic modulus ntawm tib neeg cov pob txha cortical yog kwv yees li 10-40 GPa, thaum feem ntau siv Ti-6Al-4V titanium alloy muaj qhov elastic modulus ntawm kwv yees li 110 GPa, qis dua li 150-200 GPa ntawm cov tshuaj kho mob ib txwm muaj. Cov cuab yeej sib txuam no txo qhov "kev ntxhov siab tiv thaiv" tshwm sim, tiv thaiv cov pob txha atrophy vim tsis muaj kev ntxhov siab, tso cai rau cov pob txha thiab cov pob txha deform ua ke thiab faib kev ntxhov siab sib npaug, txhawb kev sib raug zoo ntawm cov pob txha thiab cov pob txha. Qhov tseem ceeb tshaj, titanium alloys tsis muaj cov khoom tsim kev puas tsuaj rau tib neeg lub cev, muaj tshuaj lom neeg ruaj khov, tsis tso cov tshuaj lom, thiab ua rau muaj kev cuam tshuam tsawg rau lub cev tiv thaiv kab mob, tsis tshua muaj kev tsis haum tshuaj. Cov yam ntxwv no ua rau lawv xaiv tsis raug rau hauv cov ntawv thov uas muaj kev nyab xeeb siab heev, xws li kev cog hniav thiab cov hlab plawv stents.
Osseointegration yog txheej txheem tseem ceeb hauv kev cog hniav orthopedic. Tom qab lub titanium alloy implant yog muab tso rau hauv lub cev, cov proteins nyob rau hauv cov ntaub so ntswg cov ntaub so ntswg sai tsim ib tug biomolecular zaj duab xis rau nws nto, muab lub hauv paus rau adhesion thiab proliferation ntawm osteoblasts. Tom qab ntawd, osteoblasts secrete extracellular matrix Cheebtsam xws li collagen thiab hydroxyapatite. Cov tshuaj no tsis tu ncua tso nyiaj thiab crystallize, thaum kawg tsim cov pob txha tshiab uas nruj nreem koom nrog titanium alloy cog. Piv txwv li, tom qab lub hauv caug hloov pauv, cov khoom cog txuas nrog cov pob txha nyob ib puag ncig los ntawm osseointegration tom qab lub sijhawm rov zoo, tso cai rau tus neeg mob rov ua haujlwm li qub.
Siv cov tswv yim xws li photolithography thiab laser ua los tsim micro- thiab nanostructures kuj tau txais txiaj ntsig tseem ceeb. Micrometer- nplai grooves thiab protrusions tuaj yeem coj txoj kev loj hlob ntawm cov hlwb, thaum cov qauv nanoscale tuaj yeem ua rau qhov chaw roughness thiab thaj chaw tshwj xeeb, txhim kho cov protein adsorption muaj peev xwm thiab muab ntau qhov chaw adhesion rau cov hlwb, yog li ntxiv dag zog rau daim ntawv cog lus ntawm titanium alloy thiab pob txha. Tsis tas li ntawd, cov kev hloov kho tshuaj xws li ntog grafting ntawm bioactive molecules, oxidation, thiab nitridation tuaj yeem hloov cov tshuaj muaj pes tsawg leeg thiab cov khoom ntawm titanium alloy nto, ntxiv txhim kho corrosion kuj thiab biocompatibility kom tau raws li cov kev xav tau ntawm kev kho mob sib txawv.
