Thaum nws los txog rau kev phais tus txha caj qaum, cov ntaub ntawv siv rau kev kho cov cuab yeej sab hauv- xws li cov ntsia hlau thiab cov pas txuas txuas - yog qhov tseem ceeb rau kev ua tiav ntawm cov txheej txheem, ntev - lub sij hawm kev nyab xeeb, thiab lub neej zoo tom qab kev phais. Cov khoom uas koj xaiv ncaj qha cuam tshuam rau qhov tshwm sim ntawm qhov kev phais. Niaj hnub no, muaj peb yam tseem ceeb ntawm cov khoom siv feem ntau, nrog titanium alloy yog qhov kev xaiv tseem ceeb.
Mus ntsib pebtitanium khoom catalog.
1. Titanium Alloys - Tus Qauv Kub hauv Kev Kho Mob Ntsig
Titanium alloys, tshwj xeeb tshaj yogTi-6Al-4V Eli, yog cov ntaub ntawv siv dav tshaj plaws hauv kev phais txha caj qaum vim lawv qhov kev ua tau zoo tsis sib xws thiab kev lees txais.
Cov txiaj ntsig tseem ceeb:
- Biocompatibility zoo heev: Titanium alloys yog biocompatible heev, txhais tau hais tias koj lub cev tsis zoo li tsis kam lees lawv. Qhov no ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau kev cog qoob loo ntev - lub sijhawm cog qoob loo vim lawv cuam tshuam zoo nrog cov pob txha thiab cov ntaub so ntswg.
- Lub zog zoo heev - rau - Qhov hnyav piv: Titanium alloys muaj zog heev tsis tau hnav, muab kev ruaj ntseg tsis ntxiv qhov hnyav, uas tuaj yeem txo qhov tsis xis nyob rau cov neeg mob.
- Zoo tshaj Corrosion Resistance: Titanium ua tau zoo heev nyob rau hauv lub cev complex kua ib puag ncig, tiv thaiv corrosion thiab tswj nws cov qauv kev ntseeg tau ntau xyoo.
- Tsis yog -Magnetic thiab Tsawg MRI Artifacts: Ib qho txiaj ntsig tseem ceeb ntawm titanium alloys yog tias lawv tsis yog -sib nqus, tso cai rau cov neeg mob mus kuaj MRI yam tsis muaj kev pheej hmoo loj lossis cov duab cuam tshuam, uas tsis yog cov hlau tsis muaj hlau.
Hom Kev Siv:
- Ti-6Al-4V (qhov feem ntau siv)
- Ti-6Al-4V ELI (Ntxiv Tsawg Interstitial) - tshwj xeeb ua kom zoo rau cov ntawv kho mob, nws muaj kev txhim kho purity thiab qis qis ntawm impurities, ua rau nws qhov kev xaiv zoo tshaj plaws rau kev phais txha caj qaum.
- CP-Ti (ntshiab titanium)
- Beta Titanium Alloys: Muab kev sib tw ze rau qhov elasticity ntawm tib neeg cov pob txha, lawv txo qhov "kev nyuaj siab tiv thaiv" cov nyhuv uas tshwm sim thaum kho cov khoom dais ntau dhau.
Tshawb xyuas peb cov kev ua tiav tag nrhotitanium cog ntawm no.
2. Cobalt-Chrome Alloys - Siab -Txoj Kev Xaiv Lub Zog
Cobalt-chrome alloys, feem ntau cobalt-chrome-molybdenum alloys, yog lwm qhov siab- cov hlau ua tau zoo siv hauv kev phais qaum.
Cov txiaj ntsig tseem ceeb:
- Muaj zog heev thiab hardness: Cobalt-chrome alloys ua tau zoo hauv kev hnav tsis kam thiab qaug zog lub zog, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau siab - cov cheeb tsam kev ntxhov siab, xws li hauv cov neeg mob rog lossis lub lumbar qaum.
- Zoo heev Corrosion Resistance thiab Biocompatibility: Zoo li titanium, cobalt -chrome muaj zog corrosion kuj thiab ntev - lub sij hawm stability nyob rau hauv lub cev.
Lub ntsiab drawbacks:
- High Elastic Modulus: Lub alloy yog nruj dua tib neeg cov pob txha, ua rau lub peev xwm rau "kev nyuaj siab shielding," uas txhais tau hais tias lub implant yuav siv sij hawm nyob rau hauv feem ntau ntawm cov load, thiab cov pob txha yuav tsis tau txais cov neeg kho tshuab txaus stimulation, tej zaum yuav tsis muaj zog thaum lub sij hawm.
- MRI Compatibility Teeb meem: Txawm hais tias qee qhov tshiab cobalt- chrome alloys tuaj yeem raug kuaj MRI, lawv nyiam tsim cov khoom tseem ceeb dua piv rau titanium, uas tuaj yeem ua rau cov duab tsis yooj yim.
- Muaj peev xwm ion tso tawm: Txawm hais tias tsis tshua muaj, cobalt thiab chromium ions yuav raug tso tawm, ua rau muaj kev pheej hmoo rau cov tib neeg rhiab heev.
3. Stainless hlau - Classic tab sis txwv kev xaiv
Stainless hlau, tshwj xeeb316L kev kho mob - qib stainless hlau, tau siv rau ntau xyoo hauv kev phais orthopedic, tab sis tam sim no nws siv ntau dua vim nws qhov tsis zoo.
Cov txiaj ntsig tseem ceeb:
- Tus nqi -Kev ua tau zoo: Stainless hlau yog qhov pheej yig dua li titanium thiab cobalt -chrome alloys, ua rau nws muaj peev xwm siv nyiaj - kev xaiv tus phooj ywg nyob rau qee kis.
- Zoo Mechanical Strength thiab Workability: Stainless hlau paub txog nws lub peev xwm los muab kev txhim kho txhim khu kev qha thiab tuaj yeem ua tau yooj yim.
Lub ntsiab drawbacks:
- Biocompatibility tsis zoo: Stainless hlau muaj cov nickel, uas tuaj yeem ua rau muaj kev tsis haum rau qee tus neeg mob. Nyob rau tib lub sijhawm, nws cov ntaub so ntswg sib raug zoo yog qis dua ntawm titanium thiab cobalt -chrome alloys.
- Teeb meem Corrosion: Stainless hlau yog feem ntau ua rau pitting thiab crevice corrosion thaum nyob rau hauv kev sib cuag nrog lub cev kua, uas yuav ua rau implant tsis ua hauj lwm lub sij hawm.
- Mob hnyav MRI cuam tshuam: Stainless hlau yog ferromagnetic, txhais tau tias nws tuaj yeem txav mus rau hauv cov hlau nplaum muaj zog thiab tsim cov khoom qub thaum lub sijhawm MRI scans, ua rau nws tsis tsim nyog rau kev tshaj tawm - kev phais.
Kev xav zaum kawg: Cov khoom siv rau kev phais txha caj qaum Screws
Xaiv cov khoom tsim nyog rau kev phais txha caj qaum yog ib qho kev sib npaug.Titanium alloysyog cov qauv kub, muab kev sib xyaw ua ke ntawm biocompatibility tshwj xeeb, MRI kev nyab xeeb, thiab ntev -lub sij hawm durability. Cobalt-chrome alloys tseem muaj lawv qhov chaw nyob rau hauv siab - cov xwm txheej kev ntxhov siab, tab sis lawv tuaj nrog cov kev sib tw ntawm kev nruj dua thiab muaj peev xwm MRI cov teeb meem. Stainless hlau, ib zaug ib qho tseem ceeb hauv kev phais orthopedic, feem ntau tau hloov los ntawm cov ntaub ntawv siab dua vim muaj kev txhawj xeeb txog corrosion, biocompatibility, thiab MRI incompatibility.
Puas yog koj tab tom nrhiav kev ntseeg siab, siab - cov ntaub ntawv zoo rau koj qhov kev kho mob tom ntej? Hu rau Zecheng Hlauhnub no los tham txog seb peb cov kev daws teeb meem titanium zoo li cas tuaj yeem ua tau raws li koj xav tau.
