Muaj ntau cov ntaub ntawv thiab txoj hauv kev los kho cov hniav uas ploj lawm, tab sis feem ntau koj yuav tsum tau mus rau prostheses. Piv txwv li, yog tias tsis muaj lub hauv paus nyob rau hauv cov kab rov qab ntawm cov hniav los yog muaj cov ntaub ntawv kho mob, xws li mob plawv lossis ntshav qab zib. Tam sim no, muaj ntau hom kev siv prosthetics muaj rau cov neeg mob ntawm cov chaw kho hniav.
qauv tshem tawm cov hniav cuav muaj ntau qhov tsis zoo, xws li qhov tsis zoo nkauj vim yog hlau clasps thiab tsis haum rau cov monomer uas lawv muaj.
Tam sim no ib qho kev hloov tshiab uas muaj txiaj ntsig tau los los hloov tus qauv clasp thiab acrylic prostheses. Nws yog nylon prosthesis. Nylon tau tsim los ntawm cov kws tshawb fawb Asmeskas rov qab rau xyoo 1953, tab sis tau txais kev nyiam tshwj xeeb tsuas yog qee lub sijhawm tom qab, nrog rau kev xyaum siv pob tw.
Nyob zoo ib tsoom niam txiv kwv tij neej tsas sawv daws.
Nylon yog elastic, cia nws khoov tab sis tsis tawg. Kev siv cov khoom siv tes ua los ntawm cov khoom siv no tsis ua rau mob, thiab cov khoom siv tsis ua rau lub qhov ncauj tawm.
Ntxiv rau, cov hniav nylon muaj xws liCov cuab yeej tshwj xeeb, raws li qhov zoo nkauj zoo nkauj. Cov khoom siv translucent zoo kawg nkaus ua raws li cov xim thiab cov qauv ntawm cov pos hniav, thiab cov khoom khaws cia ua los ntawm cov khoom qub yog ruaj ntseg zais thiab tsis pom los ntawm sab nraud. Cov dyes siv hauv kev tsim khoom tso cai rau tus tsim kom khaws nws cov tsos txawm tias tom qab ob peb xyoos hnav. Tsis tas li ntawd, nylon prosthesis yog nyias nyias, uas muaj cov txiaj ntsig zoo tsis yog ntawm cov khoom zoo nkauj xwb, tab sis kuj ua rau nws yooj yim rau siv thiab ua kom yooj yim rau lub sijhawm hloov.
Qhov ua tau zoo ntawm cov pob qij txha kuj ua tiav los ntawm qhov tseeb tias nws tuaj yeem hnav tas li, txawm tias thaum pw tsaug zog, tshem tawm tsuas yog ntxuav. Nws lightness thiab zoo meej haum rau lub contours ntawm lub qhov ncauj kab noj hniav tso cai rau koj tsis txhob hnov qab tsis xis nyob. Ua tsaug rau cov cuab yeej siv hluav taws xob kub, cov nylon tshem tawm cov hniav yog qhov tseeb thiab ruaj khov. Thiab qhov siab ntawm lub zog ntawm cov khoom ua rau nws tuaj yeem pom zoo rau cov neeg uas nws txoj haujlwm muaj feem cuam tshuam nrog kev pheej hmoo ntawm kev raug mob.
Ntawm cov khoom zoo ntawm nylon yog non-hygroscopicity thiab tsis muaj xws li ib qho allergen li monomer. Tab sis qhov zoo tshaj plaws ntawm cov khoom siv no yog tias tsis tas yuav zom cov hniav uas nyob ib sab.
Flaws
Nrog rau qhov zoo, cov nylon prosthesis muaj nws qhov tsis zoo, uas feem ntau tshwm sim los ntawm nws cov versatility. Lub elasticity ntawm cov khoom nyob rau hauv lub xyoo ntawm kev ua hauj lwm tuaj yeem ua rau atrophy ntawm mucosa. Kev sib txhuam kuj tuaj yeem tshwm sim dhau sijhawm, txhawm rau zam qhov no, koj yuav tsum sab laj nrog kws kho hniav tsis tu ncua.
Yog ruajYog tias nylon prosthesis tawg, nws yuav luag tsis tuaj yeem kho, feem ntau yuav tsum tau hloov tag nrho.
Cov teeb meem tshwj xeeb tshwm sim nrog kev tu cov pob qij txha. Nws yog qhov zoo tshaj plaws los siv cov kev daws teeb meem tshwj xeeb rau lub hom phiaj no, vim cov txhuam zoo tib yam thiab cov tshuaj txhuam hniav puas tsuaj rau saum npoo, thiab cov quav hniav tuaj yeem tshwm sim.
Qhov kawg, qhov teeb meem loj tshaj plaws yog qhov tsis muaj ntsug load ntawm cov hniav.
Qhov twg siv nylon prostheses
Nylon kev tsim kho tau pom lawv daim ntawv thov hauv kev xyaum dav siv los daws cov teeb meem cuam tshuam nrog kev sib tw.
Lawv tau siv los hloov ob peb cov hniav thiab ib kab tag nrho.
Cov khoom siv no yog qhov zoo rau cov kab mob ntawm lub puab tsaig qis, ua rau muaj kev tsis haum tshuaj, qaug dab peg, buxism thiab lwm yam mob. Cov pos hniav thiab cov pos hniav cuav yog tsim los ntawm nws. Nylon prostheses yog indispensable nyob rau hauv cov me nyuam txoj kev prosthetics thiab rau cov neeg uas nws txoj hauj lwm yog txuam nrog rau kev raug mob.
Nylon prosthesis yog ib qho yooj yim, ruaj thiab zoo nkauj tsim uas tso cai rau cov pob qij txha ntawm txhua qhov nyuaj thiab tsis rhuav tshem cov hniav thiab cov pob txha.
