CDC Ceramic Acetabular liner ntawm lub duav pob qij txha prosthesis

Ib daim ntaub ceramic acetabular liner yog ib hom khoom tshwj xeeb uas siv rau hauv kev phais hloov pob qij txha tag nrho. Nws yog daim ntaub prosthetic liner uas muab tso rau hauv lub khob acetabular (qhov chaw ntawm pob qij txha). Nws cov nplaim hauv kev phais hloov pob qij txha tag nrho (THA) tau tsim los nrog lub hom phiaj ntawm kev txo cov pob txha tawg uas ua rau hnav rau cov neeg mob hluas thiab cov neeg mob uas tab tom hloov pob qij txha tag nrho, yog li ntawd txo qhov xav tau kev kho dua tshiab ntawm cov khoom cog thaum ntxov.
Cov ntaub thaiv qhov rooj uas ua los ntawm cov khoom siv ceramic, feem ntau yog alumina lossis zirconia. Cov ntaub ntawv no muaj ntau yam zoo dua li lwm cov ntaub thaiv qhov rooj xws li hlau lossis polyethylene:
1) Hnav Tsis Tau:
Cov ntaub ceramic muaj kev tiv thaiv kev hnav zoo heev, txhais tau tias lawv yuav tsis tshua hnav lossis tawg dhau sijhawm. Qhov no pab ua kom lub neej ntawm cov khoom cog hniav ntev dua thiab txo qhov xav tau phais kho dua tshiab. Kev Txo Kev Sib Txhuam: Cov coefficient qis ntawm kev sib txhuam ntawm cov ntaub ceramic pab txo kev sib txhuam ntawm cov ntaub thiab lub taub hau femoral (lub pob ntawm lub pob qij txha ntawm lub duav). Qhov no txo ​​qhov kev hnav thiab txo qhov ua tau ntawm kev tawg.
2) Sib xws nrog lub cev:
Vim tias cov khoom siv av nplaum yog cov khoom siv uas sib haum nrog lub cev, lawv yuav tsis muaj qhov tsis zoo rau lub cev lossis ua rau cov nqaij o. Qhov no yuav ua rau cov neeg mob tau txiaj ntsig zoo dua mus sij hawm ntev.
