Yog Titanium Rods ntau tsim nyog rau kev kho mob txha nqaj hlau dua li cov pas hlau hlau tsis muaj hlau
Hauv kev phais mob orthopedic, kev xaiv ntawm cov khoom siv txhim kho sab hauv tshwj xeeb thiab cov neeg mob posttrenative zoo li cov ntaub ntawv kho tau zoo thiab cov khoom siv biomedams thiab cov khoom siv hluav taws xob sib txawv Hauv kev thaj teb ntawm kev kho mob ntawm lawv cov txiaj ntsig ntau .
BiocompatiMility: tus yuam sij rau txo txoj kev pheej hmoo ntawm kev thim rov qab
Cov roj ntsha inertness ntawm titanium rods ua rau lawv cov ntaub ntawv zoo tshaj plaws ntawm lub cev siv roj titanium, thiab kev sib tw ua kom zoo rau ISO thoob ntiaj teb cov qauv, thiab tus lej thoob ntiaj teb 0 {. 6%, uas yog qhov qis dua li 58%, thaum muaj kev fab tshuaj tiv thaiv kab mob uas muaj kev fab yuaj
Txawm hais tias tus pas hlau stainless hlau tau txo cov ntsiab lus npib tsib xee los ntawm kev ua yeeb yaj kiab ntawm cativide, nws cov txiv ntoo uas muaj roj ntsha qhia tias tus neeckel ion concentration hauv cov ntaub so ntswg nyob ib puag ncig stainless hlau, thiab kev ua haujlwm ntev yuav ua rau mob o thiab lub pob txha ua haujlwm ntev dua.
Txhua yam hloov tau: Ntsuas kev txhawb nqa lub zog thiab cov pob txha loj hlob yuav tsum tau
Elastic modulus ntawm titanium rods ({} {{{{{{} gpa} gpa ({200-210 GPA) {{}}}}}}} {{% {{9} {9} {9} {9}
Lub teeb yuag ntawm titanium (ceev 4 {. Qhov hnyav ntawm cov neeg mob lub zog, txo cov nqaij tawv, txo qis ntawm cov neeg mob titinium ntxiv, titanium muaj zog ntau dua 500 MPa thiab tsis yooj yim los tsoo hauv qab cyclic . Kuv yog qhov tshwj xeeb tshaj yog cov poj niam thiab tus tib lub zog ua kom tiav.
Kev Nyab Xeeb Kev Nyab Xeeb: Qhov lav kom txo tau kev pheej hmoo ntawm cov teeb meem
Cov corrosion tsis kam ntawm titanium rods tso cai rau lawv kom muaj nyob rau hauv lub cev rau corrosion ntawm stainless hlau ntsia hlau yog siab li 18%}} Nyob rau hauv kev kho ntawm distal femoral pob txha lov, Tus mob kis tus kab mob ntawm titanium ntsia hlau tsuas yog 1 {{. 2%, tsawg dua li ntawm 3.5% ntawm pawg steel.
Txawm hais tias lub rigidity ntawm stainless hlau pas nrig ua tau zoo nyob rau hauv kev nyuaj siab ntawm stainless hlau cog tau tsawg dua, kev phais mob rau kev phais mob theem nrab rau Tshem tawm yog qhov siab npaum li 30%, thaum Titanium pab pawg muaj tus nqi khaws cia tas mus li 70% Vim tias biocompatibility zoo li qub.
Cov Ntawv Teev Tseg Txhaum Cai: Qhov tseeb txuam ntawm kev xav tau kev kho mob
Kev kho mob ntawm cov tub ntxhais hluas cov pob zeb: Elastic Modulus ntawm cov pob txha uas muaj kev txhim kho lub cev, tsis txhob muaj kev sib raug zoo rau cov menyuam yaus .
Kev Tsim Kho Kom Yooj Yim: Cov Khoom Siv Yooj Yim ntawm Titanium Rods ua rau lawv muaj kev pheej hmoo ntawm pob txha pob txha ua rau muaj kev ntxhov siab thiab txo qis kev pheej hmoo ntawm pob txha lov. {4}
