Kev kho mob Titanium Alloy-Lub luag haujlwm muaj zog hauv Kev Kho Mob Field

Nyob rau hauv lub ntiaj teb loj ntawm biomedical cov ntaub ntawv, titanium alloy sawv tawm nrog nws cov kev ua tau zoo heev thiab tau dhau los ua "cov khoom siv hnub qub" uas tau nyiam ntau yam hauv kev kho mob. Cov ntaub ntawv biomedical tsom mus rau kev cuam tshuam nrog cov kab mob lom rau kev kuaj mob, kho, kho lossis hloov cov ntaub so ntswg thiab cov kabmob hauv lub cev los txhim kho lawv txoj haujlwm, npog cov ntaub ntawv kho mob hlau, cov ntaub ntawv kho mob polymer, cov ntaub ntawv kho mob ceramic thiab lwm yam, ntawm cov khoom siv hlau kho mob rau qhov feem ntau, tshwj xeeb tshaj yog nyob rau hauv orthopedics thiab plawv thiab cerebrovascular cov khoom, thiab titanium alloy.

Qhov tseem ceeb ntawm Kev Kho Mob Titanium Alloys

Yog vim li cas vim li cas titanium alloys tuaj yeem ci hauv kev kho mob yog vim lawv cov yam ntxwv zoo hauv ntau yam.

Bio-kev sib raug zoo yog cov khoom muaj nqis ntawm titanium alloys. Nws muaj cov tshuaj lom neeg tsawg tshaj plaws nrog tib neeg lub cev, tsis yog - tshuaj lom thiab tsis yog - hlau nplaum, thiab raws li tib neeg cog, nws yuav tsis muaj tshuaj lom thiab muaj kev phiv rau tib neeg lub cev. Nws tuaj yeem ua ke sib haum xeeb nrog cov ntaub so ntswg thiab cov kabmob ntawm tib neeg lub cev thiab muab kev ruaj ntseg lav rau kev rov ua haujlwm ntawm lub cev.

Mechanical zog yog sib npaug zoo heev. Titanium alloy muaj cov yam ntxwv ntawm lub zog siab thiab tsis tshua muaj elastic modulus, uas tuaj yeem tsis tsuas yog ua tau raws li cov kev xav tau ntawm cov khoom cog, tab sis kuj zoo ib yam li elastic modulus ntawm tib neeg cov pob txha. Cov yam ntxwv no tuaj yeem tiv thaiv kev ntxhov siab, uas yog qhov zoo rau kev loj hlob thiab kho cov pob txha ntawm tib neeg, ua rau cov neeg mob rov zoo dua thiab zoo dua.

Corrosion kuj yuav tsum tsis txhob underestimated. Titanium alloy yog bio- cov khoom siv tsis zoo, uas muaj kev tiv thaiv corrosion zoo nyob rau hauv tib neeg lub cev, yuav tsis ua rau muaj kuab paug rau tib neeg lub cev, thiab ua kom muaj kev ruaj khov ntawm cov khoom cog hauv lub cev.

Tsis tas li ntawd, lub teeb yuag ntawm titanium alloy kuj tseem ceeb heev. Feem ntau, qhov ceev ntawm titanium alloy tsuas yog 57% ntawm stainless hlau. Tom qab cog rau hauv tib neeg lub cev, nws tuaj yeem txo qhov load ntawm tib neeg lub cev thiab ua rau cov neeg mob txav tau yooj yim dua.

Keeb kwm ntawm Kev Kho Mob Titanium Alloys

Daim ntawv thov kev kho mob titanium alloys hauv kev kho mob tsis ua tiav thaum hmo ntuj, tab sis tau dhau los ntawm cov txheej txheem ntev. Cov ntaub ntawv hlau, raws li cov ntaub ntawv biomedical functional, yog ib ceg tseem ceeb ntawm cov khoom siv science. Lawv tau siv rau hauv tib neeg cog rau ntau tshaj 400 xyoo. Biomedical titanium alloys tau dhau los ntawm peb theem.

Los ntawm 1950 txog 1980, nws yog lub sijhawm ntawm titanium ntshiab thiab Ti-6Al-4V titanium alloy. Ntshiab titanium tau siv rau hauv kev lag luam bio-tshuaj thawj zaug, lees paub tias nws zoo bio-compatibility. Ti6Al4V kuj tau siv dav hauv kev kho phais lossis hloov cov ntaub ntawv, tso lub hauv paus rau kev kho mob.

Txij xyoo 1980 txog 1990, nrog rau kev tshawb fawb tob zuj zus, tib neeg pom tias V thiab Al yog cov khoom muaj tshuaj lom rau cov kab mob. Yog li ntawd, cov kws tshawb fawb tau tsim qhov thib ob - tiam tshiab kho tshiab titanium alloy nrog Nb thiab Fe es tsis txhob V, uas ntxiv txhim kho kev nyab xeeb thiab siv tau ntawm cov khoom.

Txij li xyoo 1990, biomedical titanium alloys tau coj mus rau theem tshiab. Thaum ntxov xyoo 1990, thawj -titanium alloy Ti13Nb13Zr nrog bio zoo dua-kev sib raug zoo thiab qis elastic modulus raug tso tawm, uas tau qhib lub sijhawm tshiab ntawm biomedical -titanium alloys nrog cov khoom zoo heev thiab muab cov neeg mob ntau dua - cov kev xaiv zoo.

Kev siv dav ntawm Titanium thiab Titanium Alloys hauv Kev Kho Mob Field

Nyob rau hauv xyoo tas los no, titanium thiab nws cov alloys tau hloov pauv sai hauv kev kho mob, nrog rau kev phais yas, kev kho hniav thiab ntau yam cuab yeej kho mob ua qhov chaw, thiab cov peev txheej ntawm daim ntawv thov yog txuas mus ntxiv.

Titanium alloys ua lub luag haujlwm tseem ceeb hauv tib neeg orthopedics. Vim nws cov elastic modulus nyob ze rau tib neeg cov pob txha dua stainless hlau, titanium alloy luj tshib pob qij txha, pob qij txha, thiab lwm yam yog dav siv nyob rau hauv tib neeg orthopedic phais. Txhua xyoo, kwv yees li 100 lab tus neeg mob hauv ntiaj teb tau txais kev kho mob hloov caj npab thiab lub hauv caug pob qij txha.TitaniumLub hauv caug daim hlau yog ntau dua li cov hlau stainless hauv caug daim hlau, thiab cov teeb meem corrosion tau zoo dua qub. Tam sim no, titanium prosthetics tau maj mam hloov cov hlau prosthetics, muab cov neeg mob coj tau zoo dua.

Qhov chaw kho hniav kuj yog "qhov chaw" rau titanium alloys. Txij li thaumtitanium alloystau cog rau hauv tib neeg lub cev, cov khoom siv hlau rau kev cog hniav tau hloov pauv ntau heev. Titanium muaj affinity zoo nrog tib neeg skeletal epithelial cov ntaub so ntswg, nws cov cuab yeej cuab tam yog piv rau lwm yam hniav alloys, thiab nws ceev yog me me, ua rau cov hniav zoo nkauj. Tsis tas li ntawd, titanium hniav hniav tuaj yeem ua tau raws li qhov yuav tsum tau ua kom zoo nkauj los ntawm kev kho hniav, ua rau lawv xaiv rau kev cog hniav. Hauv kev kho mob ntawm lub ntsej muag, thaum tib neeg lub ntsej muag cov ntaub so ntswg raug mob hnyav, yuav tsum tau kho cov ntaub so ntswg hauv zos.

Nrog nws cov bio zoo- sib raug zoo thiab xav tau lub zog, titanium alloys tau dhau los ua cov khoom siv rau tib neeg lub ntsej muag kho. Ntshiab titanium mesh tau siv los ua cov pob txha pob txha hauv kev phais pob txha kom rov ua kom zoo nkauj ntawm cov neeg mob.

Kev tsim cov cuab yeej phais kuj tseem sib cais los ntawm titanium alloys. Titanium cov cuab yeej kho mob muaj kev tiv thaiv corrosion zoo, thiab qhov chaw yuav tsis raug cuam tshuam tom qab rov ua dua tshiab thiab tshuaj tua kab mob; Tsis yog- sib nqus, tuaj yeem tshem tawm qhov kev hem thawj rau cov khoom siv me me, implantable; Lub teeb yuag, tom qab hloov cov hlau tsis muaj steel, qhov hnyav tau txo qis heev, kom tus kws kho mob ua haujlwm tau yooj yim dua, thiab qib ntawm kev qaug zog ntawm tus kws kho mob tau txhim kho.

Tam sim no, titanium alloy tau siv los ua scalpel hniav, hemostatic forceps, txiab, hluav taws xob pob txha xyaum, forceps thiab lwm yam cuab yeej phais.

Qhov zoo ntawm kev kho mob titanium thiab titanium alloy cov ntaub ntawv tau txais kev pom zoo los ntawm cov neeg kho mob, thiab tseem nyiam cov neeg mob ntau dua. Xav txog yam xws li kev ua tsov ua rog, kev ua kis las, thiab kev txhim kho kev ua neej nyob, titanium thiab titanium alloys, raws li cov ntaub ntawv nyiam rau tib neeg cog, muaj qhov chaw loj hlob heev, thiab yuav muaj tseeb dhau los ua qhov kev loj hlob tshiab hauv kev siv titanium thiab pab txhawb rau tib neeg kev noj qab haus huv. ua kev pab ntau dua.
