Dab tsi yog cov qib Titanium siv hauv kev kho mob cog?
Tsis yog tag nrho cov titanium yog tsim sib npaug. Kev lag luam kho mob feem ntau siv peb qib:
| Qib | Kev sib xyaw | Ntsiab Feature | Cov ntawv thov siv |
|---|---|---|---|
| Qib 1 (GR1) | 99.5% ntshiab titanium | Softest, feem ntau ductile, zoo tshaj plaws formability | Kev kho hniav implants, pob txha daim hlau, pacemaker casings, cov cuab yeej phais |
| Qib 2 (GR2) | 99.2% ntshiab titanium | Muaj zog dua GR1, tseem muaj biocompatible | Orthopedic pins, screws, trauma implants |
| Qib 5 (GR5, Ti-6Al-4V) | Titanium alloy nrog 6% aluminium, 4% vanadium | Lub zog siab tshaj plaws, feem ntau siv rau kev thauj khoom -cov kabmob | Lub duav stems, lub hauv caug Cheebtsam, txha nraub qaum rods, pob txha screws |
Txhua qib muaj nws qhov chaw. Qhov "zoo tshaj" nyob ntawm qhov twg thiab yuav siv qhov cog li cas.
Vim li cas Qib 1 Titanium feem ntau nyiam rau qee yam kev cog ntoo?
Qib 1 Titaniumyog cov softest thiab feem ntau ductile ntawm cov khoom lag luam ntshiab qib. Nws muaj qhov tsawg kawg nkaus ntawm 99.5% titanium, nrog cov pa oxygen qis tshaj ntawm txhua qib titanium.
Qhov no tseem ceeb rau implants rau ntau yam laj thawj:
Superior osseointegration- Qhov saum npoo ntawm GR1 titanium daim ntawv cog lus tshwj xeeb zoo nrog cov pob txha cov ntaub so ntswg, ua rau nws yog qhov kev xaiv sab saum toj rau kev cog hniav thiab kev siv orthopedic qhov twg pob txha loj hlob tseem ceeb.
Qhov siab tshaj plaws biocompatibility- Tsis muaj cov ntsiab lus alloying xws li txhuas lossis vanadium, GR1 tsis muaj kev pheej hmoo ntawm cov hlau ion rhiab heev lossis ua xua. Rau cov neeg mob uas paub cov hlau rhiab heev, qhov no yog qhov zoo dua.
Zoo heev formability- GR1 tuaj yeem tsim tau txias, sib sib zog nqus nqus, thiab tshuab ua cov duab nyuaj yam tsis muaj kev tawg. Qhov no ua rau nws zoo tagnrho rau kev cog qoob loo thiab cov cuab yeej phais mob sib txawv.
Corrosion kuj- Qib 1 titanium tiv thaiv corrosion hauv lub cev zoo dua li yuav luag txhua yam hlau. Thaum cog, nws tseem nyob ruaj khov rau xyoo lawm.
Yog li thaum biocompatibility yog qhov tseem ceeb thib ib, GR1 feem ntau yog cov lus teb.
Thaum twg Koj Yuav Tsum Xaiv Qib 2 Titanium Hloov?
Qib 2 TitaniumNws kuj tseem yog kev lag luam ntshiab, tab sis nws muaj cov ntsiab lus oxygen siab dua me ntsis (tsawg dua lossis sib npaug li 0.25% vs. Tsawg dua lossis sib npaug rau 0.18% hauv GR1). Qhov no ua rau nws muaj zog ntau dua thaum tswj kev ua haujlwm zoo corrosion thiab biocompatibility.
Xaiv Qib 2 thaum:
Lub implant yuav tsum taume ntsis zog duatshaj GR1 tuaj yeem muab tau
Koj xav tau qhov sib npaug ntawmformability thiab mechanical kev ua tau zoo
Daim ntawv thov yogkev raug mob fixation(screws, pins, daim hlau) qhov twg yuav tsum muaj zog me ntsis
Hauv kev xyaum, ntau tus kws tsim khoom siv kho mob siv Qib 2 raws li "default" kev xaiv titanium ntshiab vim nws muaj qhov nruab nrab zoo. Tab sis rau cov ntawv thov xav tau qhov siab tshaj plaws ductility lossis purest biocompatibility, GR1 tseem yog qhov kev xaiv.
Dab tsi txog Qib 5 Titanium? Puas yog nws zoo dua rau Load-Bearing Implants?
Qib 5 Titanium (Ti-6Al-4V)yog alpha-beta alloy. Nws muaj zog ntau dua li Qib 1 thiab Qib 2, nrog lub zog tensile ntawm kwv yees li 895 MPa - ze li plaub npaug ntawm GR1.
Qhov no ua rau nws cov khoom ntawm kev xaiv rau:
Hip stems thiab femoral Cheebtsam
Lub hauv caug hloov tshuab
Pedicle rods thiab pedicle screws
Ntev pob txha fixation li
Txawm li cas los xij, Qib 5 muaj txhuas thiab vanadium. Txawm hais tias cov ntsiab lus no feem ntau suav hais tias muaj kev nyab xeeb hauv ntau daim ntawv, muaj kev sib tham txuas ntxiv txog qhov muaj peev xwm ntev - lub sij hawm hlau ion tso tawm. Rau cov neeg mob uas muaj kev txhawj xeeb hypersensitivity, cov qib ntshiab titanium (GR1 lossis GR2) feem ntau pom zoo.
Yog li qib 5 "zoo dua"? Rau lub zog, yog. Rau biocompatibility, tsis muaj. Nws nyob ntawm seb qhov cog cog yuav tsum ua li cas.
Yuav Ua Li Cas GR1 thiab GR5 Sib Piv Ib Sab?
| Khoom | Qib 1 (GR1) | Qib 5 (Ti-6Al-4V) |
|---|---|---|
| Tensile zog | 240 MPa | 895mpa ua |
| Yield zog | 170 MPa | 830 MPa ua |
| Biocompatibility | Siab tshaj - tsis muaj alloying ntsiab | Zoo heev, tab sis muaj Al / V |
| Formability | Zoo heev - tuaj yeem sib sib zog nqus kos | Txwv – nyuaj rau tsim |
| Corrosion Resistance | Zoo heev | Zoo heev |
| Tej kev siv | Kev kho hniav implants, pob txha daim hlau, pacemaker casings | Lub duav stems, lub hauv caug Cheebtsam, tus txha caj qaum |
Qhov kev xaiv los ntawm seb qhov cog cog yuav tsum tau nqa cov khoom hnyav lossis tsuas yog nyob nyab xeeb hauv lub cev.
Puas yog Qib 1 Titanium suav tias yog "Implant Qib"?
Yog lawm.
Qib 1 Titanium ua tau raws li ASTM F67 thiab ISO 5832-2 tus qauv, uas yog cov kev paub tshwj xeeb rau unalloyed titanium rau daim ntawv thov kev phais.
Qhov no txhais tau tias GR1 tau raug cais raws li kev cog qoob loo- cov khoom qib. Nws tau siv rau ntau xyoo hauv:
Kev kho hniav implants
Craniofacial daim hlau thiab screws
Pacemaker casings
Cov pob txha fixation
Cov cuab yeej phais
Yog li yog tias koj tab tom nrhiav GR1 rau daim ntawv thov kev kho mob, koj tuaj yeem ntseeg tau tias nws ua tau raws li cov qauv kev cai.
Cov kws phais neeg thiab cov neeg tsim khoom hais li cas?
Hauv kev xyaum, kev xaiv feem ntau ua raws li txoj cai yooj yim:
Rau kev sib txuas ntawm cov pob txha thiab cov ntaub so ntswg- Xaiv Qib 1 (GR1)
Rau kev txhim kho kev puas tsuaj dav dav- Xaiv Qib 2 (GR2)
Rau siab -stress load- bearing- Xaiv Qib 5 (GR5)
Cov kws kho hniav cog lus, piv txwv li, ntau dhau nyiam Qib 1 vim nws qhov zoo tshaj osseointegration thiab cov yam ntxwv saum npoo. Orthopedic trauma tuam txhab uas muag feem ntau siv Qib 2 rau daim hlau thiab cov ntsia hlau. Cov tuam txhab hloov pauv sib koom ua ke tso siab rau qib 5 kom muaj zog.
Tsis muaj ib qho "zoo tshaj" qib ntawm titanium rau kev cog qoob loo. Qhov kev xaiv yog nyob ntawm daim ntawv thov.
Tab sis yog tias koj qhov tseem ceeb yog:
| Ua ntej | Pom zoo Qib |
|---|---|
| Pureest biocompatibility | Qib 1 (GR1) |
| Maximum ductility thiab formability | Qib 1 (GR1) |
| Pob txha sib txuas (osseointegration) | Qib 1 (GR1) |
| Sib npaug zog thiab biocompatibility | Qib 2 (GR2) |
| Lub zog siab tshaj plaws rau kev thauj khoom -cov kabmob | Qib 5 (GR5) |
Rau ntau daim ntawv cog lus - tshwj xeeb tshaj yog kho hniav, craniofacial, thiab cov khoom siv phais kev cai -Qib 1 Titanium yog qhov nyiam xaivvim nws muaj kev sib xyaw ua ke zoo tshaj plaws ntawm biocompatibility, corrosion kuj, thiab formability.
Yog tias koj tab tom nrhiav titanium rau kev kho mob cog thiab xav sib tham txog qib twg haum rau koj daim ntawv thov tshwj xeeb, thov hu rau dawb. Peb muab GR1, GR2, thiab GR5 titanium nrog tag nrho cov ntaub ntawv traceability thiab ASTM F67 / F136 ntawv pov thawj.
