Muaj ntau ntau yam vim li cas PEEK yog cov khoom siv kho hniav zoo tagnrho. Nws yog ib qho kev xaiv pem hauv ntej rau kev kho hniav, tshem tawm ib feem ntawm cov hniav hniav thiab txhim kho cov txheej txheem prosthetic, thiab cov kws tshawb fawb tau pom zoo txog nws cov peev xwm hauv kev siv ntxiv.
1. Biocompatibility - PEEK's biocompatibility tau raug pov thawj thiab ntau qhov kev tshawb fawb tau lees paub tias nws tsis muaj tshuaj lom. Txawm tias tom qab siv ntau txhiab tus neeg mob, PEEK yog qhov kev xaiv zoo tshaj plaws piv rau cov hlau, uas ua rau muaj kev tsis haum tshuaj ntau npaum li 15 feem pua ntawm cov pejxeem.
PEEK cov khoom muaj nyob rau hauv cov pob txha caj qaum, cov khoom siv kho mob, lub duav thiab lub hauv caug arthroplasty thiab lwm yam khoom siv kho mob. Hauv txhua qhov piv txwv, tsis muaj teeb meem nrog PEEK txoj kev nyab xeeb hauv lub cev.
2. Cov khoom siv kho tshuab - PEEK muaj lub zog zoo dua - rau - qhov hnyav piv, thiab qhov no yog qhov tseem ceeb tshwj xeeb rau kev cog hniav thiab cov khoom siv. Piv nrog rau hlau, PEEK yog sib dua thiab xis dua rau cov neeg mob. Qhov kev nplij siab ntxiv no tsis cuam tshuam rau kev ua haujlwm ntev, vim PEEK tuaj yeem ua haujlwm abrasive thiab compressive rog yam tsis poob nws txoj kev ncaj ncees. Cov polymer no tiv thaiv corrosion thiab absorbs dej ntawm tus nqi tsawg, yog li nws tuaj yeem siv tau rau ntau xyoo yam tsis muaj kev poob qis hauv kev ua haujlwm.
3. Muaj peev xwm ua tau machined – Cov kws kho hniav vam khom rau lub computer-pab tsim (CAD) thiab machining (CAM) ntau dua puas tau, thiab PEEK yog ib tug zoo meej haum rau qhov no. Ib qho tseem ceeb hauv cov cuab yeej kho hniav niaj hnub no yog qhov haum rau tus neeg mob lub cev, thiab CAD / CAM yog qhov tsim nyog los tsim nws. Qhov no ua kom lub cuab yeej yuav so zoo, ua haujlwm zoo thiab kav ntev li ntev tau.
Yog tias PEEK yog machined rau cov chaw tsim khoom tshwj xeeb, nws yuav khaws nws cov khoom tom qab milling. Qhov kev ruaj ntseg ntxiv no tso cai rau kev hloov pauv ntau dua thaum lub sijhawm tsim qauv thiab ua rau nws yooj yim dua rau cov kws kho hniav kom haum lawv cov neeg mob nrog cov khoom siv kev cai.
PEEK qhov yooj yim compatibility nrog CAD / CAM txoj kev kuj txhais tau tias nws tuaj yeem ua tiav sai thiab tsis tu ncua. Hauv luv luv, PEEK cov khoom siv tuaj yeem ntseeg tau thiab ua tau sai.
4. Flexibility - Qhov no siab tshaj - polymer kev ua tau zoo yog ruaj khov, tab sis tsis tawv. Thaum unfilled, nws muaj ib tug modulus uas zoo ib yam li cov pob txha cortical, ua PEEK ib tug muaj zog, saj zawg zog kho hniav cov ntaub ntawv. Nrog nws cov kev hloov pauv ntxiv, PEEK yuav hnov ntxhiab hauv qhov ncauj thiab nyob twj ywm txawm tias tom qab xyoo tom thiab zom. Cov cuab yeej kho hniav yuav tsum tuav lawv cov duab thaum raug kev ntxhov siab tas li, thiab PEEK yog cov polymers zoo tshaj plaws ntawm kev ua li ntawd.
5. Radiolucency – PEEK cov pob txha-zoo li modulus thiab radiolucency yog ob yam uas tau pib coj cov kws tshawb fawb txog kev kho mob rau PEEK, thiab nws tseem yog ib qho ntawm cov khoom siv polymer. Nyob rau hauv xyoo tas los no, kev tshawb fawb rau hauv PEEK kev cog hniav tau pom tias cov khoom muaj peev xwm loj heev hauv cheeb tsam no.
PEEK's radiolucency yog qhov muaj txiaj ntsig zoo thaum cov khoom siv hauv txhua txoj kev cog qoob loo. Thaum cog, cov polymer yuav tsis pom kev cuam tshuam ntawm X-rays, CT lossis MRI scans. Raws li X-rays yog qhov tseem ceeb rau kev kuaj hniav, PEEK qhov tsis pom ntawm cov duab yuav ua kom cov kws kho hniav tuaj yeem ua lawv txoj haujlwm hauv kev saib xyuas lawv cov neeg mob kev noj qab haus huv. Hauv qhov xwm txheej uas PEEK qhov kev tshaj tawm xov tooj cua zoo tshaj plaws tuaj yeem suav tias yog kev cuam tshuam, cov polymer tuaj yeem ntxiv nrog cov khoom ntxiv xws li Barium Sulfate los tsim qhov sib txawv zoo dua.
6. Aesthetics - Ib yam li PEEK tuaj yeem tsim los rau cov duab kev cai yooj yim, nws tuaj yeem ua xim raws li tus neeg mob. Hlau, los ntawm qhov sib txawv, feem ntau tsis tuaj yeem nkaum hauv lub qhov ncauj, thiab qhov no yog qhov teeb meem rau cov neeg mob.
PEEK yog ib qho khoom siv kho hniav yooj yim los ua ke rau hauv lub qhov ncauj kab noj hniav, vim nws cov xim tuaj yeem hloov kho thaum ua haujlwm. Txawm tias tag nrho cov hniav hniav tuaj yeem tsim los ua kom pom tseeb, ua kom cov neeg mob tuaj yeem hais lus, luag ntxhi thiab noj nrog kev ntseeg siab.
7. saj nruab nrab - Tseem muaj lwm qhov kev txhawj xeeb nrog cov khoom siv hlau yog tias lawv tsim cov xim hlau rau ntau tus neeg mob. Qhov no tsis yog kev txhawj xeeb txog kev noj qab haus huv, tab sis yog ib qho kev ntxhov siab tas mus li rau cov neeg mob uas tsis xav kom nco ntsoov tias lawv muaj hniav hniav lossis lub hauv paus hauv qhov chaw.
Hmoov zoo, PEEK yog ib qho saj - cov khoom siv kho hniav nruab nrab, muab cov neeg mob ib txheej ntxiv ntawm kev nplij siab uas lawv tsis tuaj yeem tau los ntawm cov khoom siv hlau.
Yilink PEEK yog koj cov khoom siv CAD/CAM digital milling rau qhov tshwj xeeb hauv kev tsim qauv zoo rau kev siv sijhawm ntev -. Lub teeb yuag thiab ntau yam nws cov khoom siv kho tshuab zoo heev yog impressive. Nws kuj yog qhov tshwj xeeb tshaj yog biocompatible.Cov xim zoo heev thiab hlau-dawb Yilink PEEK blanks muaj kev cia siab ntev ntev rau ntau yam kev kho hniav kho hniav rau lub hauv paus txheej txheem los yog cog superstructures, nyob rau hauv lub anterior los yog posterior cheeb tsam, semi- mus tas li.
