Hauv kev kho mob, yuav ua li cas npaj cov pob txha scaffolds nrog siab biocompatibility yeej ib txwm yog ib qho ntawm cov kev tshawb fawb kub. Txhua xyoo nyob rau hauv kuv lub teb chaws, muaj tsis muaj tsawg tshaj li 3 lab tus neeg mob ntawm kev kho mob tib neeg pob txha implantation, thiab tus nqi ntawm txhua rooj plaub yog kaum txhiab mus rau ntau tshaj 100,000. Muaj peev xwm loj. Txawm li cas los xij, cov cib fim thiab cov teeb meem sib koom ua ke, thiab tseem muaj teeb meem tom qab qhov kev tshawb fawb kho mob no uas tsis tuaj yeem tsis quav ntsej. Siv cov kev phais hloov kev sib koom tes, yog ib txoj hauv kev siv los kho kev sib koom ua haujlwm tsis zoo hauv kev kho mob, ua piv txwv. Txoj kev kho mob no tuaj yeem kho qhov sib koom ua ke thiab ua haujlwm. Nrog rau kev kawm tob ntawm kev sib koom tes ntawm lub cev thiab kev sib koom ua ke biomechanics, nws pom tias ob qhov teeb meem loj tam sim no ntsib yog:

Cov teeb meem kev lag luam: Kev npaj ntawm kev hloov pauv kev sib koom tes feem ntau yog ua raws li cov ntaub ntawv duab ib txwm muaj, thiab nws nyuaj rau kev nkag siab thiab raug cuam tshuam cov ntaub ntawv ntawm cov kab mob sib koom ua ke, tshwj xeeb tshaj yog kev tuav ntawm lub kaum sab xis ntawm osteotomy, uas feem ntau yog nyob ntawm tus neeg teb xov tooj kev paub thiab tus kheej. kev paub. Kuj tseem muaj qhov teeb meem uas tus qauv ntawm prosthesis tsis sib haum nrog cov qauv anatomical tiag tiag ntawm tus neeg mob, uas cuam tshuam rau kev rov qab los ntawm kev sib koom ua haujlwm ntawm tus neeg mob.
Cov khoom siv teeb meem: xaiv cov khoom siv kho mob tib neeg cov pob txha cog, cov ntaub ntawv siv ua ntej yog stainless hlau, npib tsib xee-chromium alloy, npib tsib xee-titanium alloy, thiab GR5 titanium alloy tau fashionable hauv 2 lossis 3 xyoo dhau los. Cov ntaub ntawv no muaj cov npib tsib xee, chromium, txhuas, vanadium, thiab lwm yam teeb meem, thiab vim hais tias nws elastic modulus tshaj tib neeg cov pob txha ntau dhau thiab cov khoom muaj ib tug tsawg affinity nrog tib neeg lub cev, qhov tshwm sim ntawm "pob txha tsis-stick" yog nquag. tshwm sim. Cov kws tshaj lij hauv kev kho mob thiab kev ua lag luam xav tau cov ntaub ntawv tshiab uas tsis muaj tshuaj lom, tsis muaj mob, thiab muaj kev sib raug zoo ntawm tib neeg los txhim kho qhov xwm txheej tam sim no.
Kev daws: kev daws teeb meem - 3D tshuab luam ntawv
3D luam ntawv yog ib lub tshuab uas tsim cov khoom los ntawm txheej los ntawm-txheej luam ntawv raws li cov qauv ntaub ntawv, siv cov hmoov hlau los yog cov ntaub ntawv yas-bondable.
1. 3D tshuab luam ntawv muaj cov yam ntxwv ntawm qhov tseeb thiab tus kheej, thiab nws daim ntawv thov hauv kev kho mob, tshwj xeeb tshaj yog kev tsim cov khoom siv dag zog sib koom ua ke, txuas ntxiv nthuav dav los ntawm kev siv computer-aided tsim.
2. 3D luam ntawv thev naus laus zis tuaj yeem siv los kho cov ntaub so ntswg tsis xws luag los ntawm kev cog ntoo nrog kev hloov pauv siab thiab cov ntaub so ntswg zoo sib xws.
3. Nrog rau kev txhim kho txuas ntxiv ntawm thev naus laus zis, 3D luam ntawv thev naus laus zis yuav maj mam txhim kho, thiab nws daim ntawv thov hauv kev kho cov kab mob orthopedic tuaj yeem tsis tsuas yog txhim kho cov txiaj ntsig kev kho mob xwb tab sis kuj tseem muaj qee yam kev txhawb nqa tseem ceeb rau kev txhim kho cov neeg mob.
Khoom siv daws teeb meem - Tantalum Metal Materials:
Tantalum, cov khoom siv hlau, nyiam cov neeg ua haujlwm kho mob ntau dua thiab cov kws tshawb fawb cov ntaub ntawv nrog nws qhov tshwj xeeb zoo.
Cov yam ntxwv ntawm tantalum
Zoo corrosion kuj; Nyob rau hauv chav tsev kub, tantalum yuav tsis hnov mob nrog hydrochloric acid, concentrated nitric acid, los yog txawm aqua regia, thiab yuav tsis zoo tib yam inorganic ntsev corrode nws.
Zoo biocompatibility: Tsis zoo li cov khoom siv hlau kho mob, cov ntaub so ntswg lom yuav loj hlob ntawm tantalum tom qab cog rau lub sijhawm, ib yam li ntawm cov pob txha tiag. Yog li ntawd, tantalum tseem hu ua "metalphile"
Tsim nyog elastic modulus: Lub elastic modulus ntawm tantalum nrog ib tug tshwj xeeb pore qauv yog nruab nrab ntawm cov tib neeg cov pob txha thiab cortical pob txha, tshwj xeeb tshaj yog haum rau cov pob txha hloov, sib koom tes hloov, thiab tib neeg cov ntaub so ntswg filling.
Thaum lub Kaum Ib Hlis 2017, kuv lub teb chaws tau ua tiav lub ntiaj teb thawj tag nrho lub hauv caug kho mob phais nrog tus kheej 3D luam tawm tantalum hlau pad implantation. Raws li cov lus ceeb toom, tus yuam sij ua kom tiav cov haujlwm yog nyob rau hauv lub computer-pab tsim ntawm lub ncoo thiab precision ntawm hlau 3D luam ntawv. 3D luam tawm tantalum hlau spacer tailored rau cov neeg mob muaj ib tug zoo haum thiab nto roughness, uas zoo kawg nkaus nyob rau hauv lub loj loj cov pob txha tsis xws luag thiab xyuas kom meej qhov pib stability ntawm tantalum hlau spacer implantation tom qab cov pob txha tsis xws luag. Qhov saum npoo yog ntxhib thiab ntxeem tau. Kev tsim cov pob txha trabecular tuaj yeem ua rau cov pob txha autologous loj hlob mus rau hauv cov hlau pores sai, thiaj li kom tau txais kev ruaj ntseg ntev ntawm cov pob txha thiab cov pob txha autologous, ua kom yooj yim rau cov txheej txheem ua haujlwm thiab txo cov teeb meem ntawm kev phais. Txhua lub thev naus laus zis tshiab ntsib txoj hauv kev thiab cov teeb meem hauv nws txoj kev txhim kho, thiab 3D luam ntawv tantalum hlau tsis muaj qhov tshwj xeeb. Tej yam xws li tus nqi, efficiency, precision, thiab lwm yam. txhua yam muaj shortcomings. Cov kev taw qhia ntawm cov cuab yeej siv no yog qhov tseeb, thiab cov kev cia siab yuav ci. Nyob rau hauv lub neej yav tom ntej, ntau tus kws tshawb fawb yuav tsum tau ua haujlwm txuas ntxiv los tsim cov txuj ci tseem ceeb ntxiv rau kev lag luam kho mob thiab coj cov xov xwm zoo ntxiv rau feem coob ntawm cov neeg mob pob txha.
Yog tias koj xav yuav khoompolished tantalum daim hlauthiab lwm yam khoom siv tantalum, thov muab qhov tseem ceeb rau Baoji Yusheng Hlau Technology Co., Ltd. Peb tuaj yeem ua peb qhov zoo tshaj plaws los ntawm kev xaiv raw khoom kom tiav cov khoom xa tuaj.
