Yuav ua li cas cov pas nrig titanium pab cov pob txha kho
Hauv kev phais mob orthopedic, cov pas nrig titanium tau dhau los ua tus pab "tsis pom kev" los txhawb cov pob txha kho kom zoo. Los ntawm kev kho cov pob txha lov rau kev hloov pauv ntawm kev hloov pauv ntawm pob txha los kho cov khoom siv kev tshawb fawb thiab cov cuab yeej siv tshuaj kho mob.
Biocompatibility: "Seamless kev sib tham" nrog tib neeg cov ntaub so ntswg
Lub biocompatibility ntawm titanium rods los ntawm ruaj khov titanium oxide (ti₂) txheej tsim ntawm nws cov npoo. Qhov no inert txwv txwv kev tso tawm cov hlau ions thiab zam kev tiv thaiv kev tiv thaiv. Cov ntaub ntawv kuaj mob qhia tau tias qhov kev tsis lees txais ntawm titanium kev cog lus tsawg dua 0.1%, uas yog qhov qis dua li cov hlau tsis muaj zog (3%-lical-alloy (2% -4%). Piv txwv li, hauv lub duav hloov kev phais, ntawm poj niam cov nqaj tsim los ntawm cov pob txha titanity, thiab cov pob txha ua kom pom kev, ua "kev sib koom ua ke ua pob".
Ntau tus neeg sau ntawv yog tias cov alloys tshiab tshiab (xws li Ti-6NB) txuas ntxiv txo txoj kev pheej hmoo ntawm kev pheej hmoo ntawm lub sijhawm ntev los ntawm kev tshem cov tshuaj lom vanadium. Ti-5AL-2.5FE Alloy Tsim Tawm hauv Switzerland tau dhau los ntawm ISO 10993 Kev tiv thaiv kev nyab xeeb rau kev phais mob ntev xws li Scoliosis kho rau cov menyuam yaus.
Neeg kho tshuab hloov tau: "Elastic Buffer" uas simulates pob txha ntuj
Elastic modulus ntawm ntshiab titanium (105 GPA) tsuas yog 53% ntawm qhov uas tsis xeb hlau, uas yog ze rau tib neeg cortical pob txha (10-30 GPA). Qhov kev sib txuam kho tshuab no tuaj yeem txo cov kev ntxhov siab "kev nyuaj siab ntawm cov pob txha vim lawv lub siab tawv, ua rau muaj kev txo qis hauv cov pob txha ceev. Cov kev sim tsiaj qhia tau tias cov pob txha ua kom muaj zog ntawm tus poj niam yog 42% qis dua li kev phais mob stainless yog, uas cuam tshuam rau kev tiv thaiv loosening.
Hauv kev teb ntawm kev kho mob plab, txoj kev kom zoo elastic ntawm titanium pas nrig tshwj xeeb tshaj yog muaj txiaj ntsig. Piv txwv li, rau cov neeg mob nrog cov tub ntxhais hluas cov lus ntuas, xws li Ti-ni nco alloy zog, tuaj yeem ua kom muaj kev txhim kho lub zog ntawm kev loj hlob ntawm kev loj hlob thiab kev loj hlob. Cov chaw kho mob taug xyuas kev ua tau pom tias tus txha caj qaum txhim kho kev txhim kho ntawm cov neeg mob sab txha caj qaum tau mus txog 89% 2 xyoos tom qab phais tas, thiab tsis muaj kev mob hnyav.
Engine Engineering Technology: "lom lom neeg hloov pauv" los ua kom cov pob txha ua haujlwm
Niaj hnub niaj hnub titanium qws tuaj yeem nquag ua kom osteocyte proliferation los ntawm cov kev hloov kho cov khoom siv. Piv txwv li:
Micro-nano cov qauv kev tsim kho: Ultrasonic acid etching + anodizing cov pits (lub taub 5,00nm) nyob rau saum npoo ntawm titanium pas nrig. Cov qauv ntau qib no tuaj yeem nce cov zog saum npoo av, txhawb cov pob txha morphogenetic protein (BMP-2) adsorption, thiab nce qhov qauv Adhesion OsteoTion los ntawm 3 zaug. Tus nas femoral kev sim ua kom pom tias cov pob txha tshiab nyob ib ncig ntawm qhov hloov kho titanium pas dej tau nce los ntawm 67% piv nrog pab pawg tsis muaj kev pab.
Cov txheej txheej Bioting: Hydroxyapatite (HA) txheej yog muab los ntawm Plasma txau thev naus laus zis los simulate cov pob txha pob txha ua kom zoo nkauj. Daim ntawv thov ntawm ha-coated titanium pas nrig qhia tau hais tias nws cov pob txha sib nrawm yog 50% siab dua ntawm cov ntshiab titanium, thiab cov kws kho mob ruaj khov tuaj yeem ua tiav 3 lub hlis tom qab phais.
Tshuaj Kho Mob Kev Tso Tawm Tawm Tsam: LL-37 antimicrobial Peptide yog thauj khoom nyob rau saum npoo ntawm titanium rods kom ua tiav cov kev sib kis tau ntawm "los tiv thaiv kev kho". Hauv cov kev sim vito tau lees paub tias cov khoom no tuaj yeem cuam tshuam rau M2 hom (anti-inflammatory kho kho mob.
3D Luam Ntawv Tshuab: "Kev Tsim Kho Kev Tsim Kho" Rau Kev Kho Tus Kheej
Kev kho mob ntxiv rau kev tsim khoom siv ntxiv rau kev ua haujlwm rau cov pas nrig titanium kom ua tiav "txiav ua" tsim qauv ". Piv txwv li:
Complex anatomical kev yoog raws: qhov tsis xws luag xws li pob txha pob txha caj dab, 3D luam tawm titanium mesh tuaj yeem kho cov qauv ntxig raws li cov ntaub ntawv. Nws cov porosity (60% -80%) thiab pore loj (300-600μ Cov ntaub ntawv kuaj mob qhia tau tias tus kab mob postperative uas pom tias cov kev cog hniav uas tsuas yog 2.3%, uas yog qis dua li cov khoom siv titanium.
Gradient Elicastic Tsim: Los kho cov thickness ntawm titanium hmoov txheej thiab lub zog laser, titanium qws nrog gradient Elastic Modulus tuaj yeem tsim. Piv txwv li, hauv kev sib txawv ntawm kev hloov pauv ntawm poj niam, Elastic Modulus nyob ze qhov sib koom ua ke kawg tuaj yeem txo rau 40 GPA los txo kev ntxhov siab; Thaum lub diahonseal ntu khaws cia 80 GPA los muab kev txhawb nqa txaus. Cov qauv tsim no txo qhov xwm txheej ntawm periprosthetic pob txha lov ntawm 12% rau 3.1%.
Cov ntaub ntawv thov kho mob: "Puv cov kev pab them nqi zog" ntawm kev pov tseg rau degeneration
Lub chaw kuaj mob ntawm cov pas nrig titanium tau nkag mus rau tag nrho cov teb chaws ntawm Orthopedics:
Kev Nyab Xeeb Orthopedics: Hauv kev kho mob ntawm Tibial Plateau Slactures ua kom zoo rau lub sijhawm kho kom zoo yog nce rau 92%.
Kev phais kab mob: Hauv cov khoom siv sib koom ua ke, cov tais sib npaug yuav txo tus nqi ntawm cov roj polyethylene ntawm cov yos prosthesis mus txog ntau dua 95%.
Kev phais mob txha caj qaum: Rau cov kab mob txha caj qaum fusion, cov kev siv sib xyaw ua ke los ntawm 78% rau 91%, thiab txo qhov kev tshwm sim ntawm kev mob ncua ntev los ntawm 56%.
Los ntawm nws thawj lub luag haujlwm ua cov khoom siv inert rau nws lub luag haujlwm ntawm cov pob txha uas muaj peev xwm ua kom muaj cov tshuaj thiab cov khoom siv science. Nws tsis tsuas yog muab kev txhawb nqa ruaj khov rau cov pob txha nrog nws cov txheej txheem hloov kho cov txheej txheem "los ntawm kev tsim kho cov kev tsim kho tshiab xws li engnological thiab 3D luam ntawv.
