Implantation ntawm Periosteum ntawm Titanium Grafts

Cov kws tshawb fawb los ntawm Kws qhia ntawv ntawm Nuclear Technology Engineering thiab Kws Qhia Ntawv ntawm Kev Tsim Kho Tshiab ntawm Kev Tsim Kho Tshiab ntawm Tomsk Polytechnic University hauv Russia, nrog rau cov kws tshaj lij txawv teb chaws hauv cov khoom siv kho mob, tau tsim ib txoj hauv kev siv titanium dioxide nanotubes. Lub catheter yog coated nrog calcium phosphate txheej. Cov txheej txheem ntawm txheej yog tib yam li cov pob txha ntawm tib neeg. Nws yog sib npaug los npog titanium grafts nrog periosteum, uas tuaj yeem txhim kho qhov ciaj sia taus ntawm titanium grafts.

Cov kws tshawb fawb tau sau tseg tias titanium yog dav siv rau grafts, tab sis ob leeg muaj qhov sib txawv elasticity. Titanium yog ib qho nyuaj tshaj li cov pob txha. Raws li qhov tshwm sim, titanium raug rau cov khoom siv ntau dua li cov pob txha thaum tus neeg mob ua haujlwm, uas tuaj yeem ua rau cov pob txha puas. "Lub nanoscale catheter pab daws qhov teeb meem no thiab zam kev titanium mus rau cov khoom siv ntau dua li cov ntaub so ntswg," hais tias cov tub ntxhais kawm tiav Roman Chernozem.

Tsis tas li ntawd, lub hollow nanoscale catheters yog qhov zoo tagnrho rau kev sau cov tshuaj, xa mus rau lub cev qhov twg nws xav tau, thiab tswj tus nqi ntawm cov tshuaj xa tuaj.
