Abstract

ENDOPROTESIS CON UN COMPONENTE DE PROTESIS(4)DE PLASTICO VISCOELASTICO, COMO POLIETILENO PARA ASEGURAR A UN COMPONENTE DE PROTESIS(1), DE MATERIAL MAS FUERTE, COMO METAL, POR MEDIO DE UN TORNILLO (3). EL TORNILLO TIENE UN ELEMENTO QUE EVITA SU AFLOJAMIENTO, CONSISTENTE EN UNA SERIE DE SALIENTES (14) Y REBAJES QUE SE ACOPLAN EN UNA SUPERFICIE (13) DEL PLASTICO, DEFORMABLE PLASTICAMENTE. CON ESTE PROPOSITO, SE SELECCIONAN UNA PAREJA DE SUPERFICIES, SOBRE EL TORNILLO, Y SOBRE EL COMPONENTE PLASTICO, CUYO ESPACIADO ESTA FIJADO ESTRUCTURALMENTE (PRINCIPALMENTE POR LOS TOPES DUROS 8 Y 9) Y QUE NO TRANSMITE LA FUERZA CON LA QUE EL TORNILLO ESTA APRETADO.
