CDC Ceramic Acetabular liner ntawm hip ob leeg prosthesis

Ceramic acetabular liner yog ib hom tshwj xeeb ntawm cov khoom siv hauv tag nrho lub duav hloov phais.Nws yog cov kab mob prosthetic uas tau muab tso rau hauv lub khob acetabular (socket ib feem ntawm lub duav sib koom).Nws cov kabmob qhov chaw hauv tag nrho lub duav arthroplasty (THA) tau tsim nrog lub hom phiaj ntawm kev txo qis kev hnav-induced osteolysis nyob rau hauv cov tub ntxhais hluas thiab cov neeg mob ua haujlwm tau hloov tag nrho lub duav, yog li theoretically txo qhov kev xav tau ntawm aseptic loosening thaum ntxov kho ntawm qhov cog.
Ceramic acetabular liners yog tsim los ntawm cov khoom siv ceramic, feem ntau alumina lossis zirconia.Cov ntaub ntawv no muaj ntau qhov zoo dua lwm cov ntaub ntawv hauv ob sab phlu xws li hlau lossis polyethylene:
1) Hnav Resistance:
Ceramic linings muaj kev hnav zoo heev, txhais tau tias lawv tsis tshua hnav lossis tawg thaum lub sijhawm.Qhov no pab ua kom lub neej ntev ntawm kev cog qoob loo thiab txo qhov kev xav tau kev kho dua tshiab.Txo kev sib txhuam: Qhov qis coefficient ntawm kev sib txhuam ntawm cov khoom siv ceramic pab txo kev sib txhuam ntawm lub liner thiab lub taub hau femoral (lub pob ntawm lub duav sib koom).Qhov no txo ​​qis hnav thiab txo qhov muaj peev xwm ntawm dislocation.
2) Biocompatible:
Vim tias ceramics yog cov khoom siv biocompatible, lawv tsis tshua muaj kev cuam tshuam tsis zoo rau lub cev lossis ua rau cov ntaub so ntswg mob.Cov txiaj ntsig zoo rau lub sijhawm ntev rau cov neeg mob yuav tshwm sim los ntawm qhov no.
