Abstract

L'invenzione riguarda una protesi pluricomposta per l'impiego in traumatologia, ortopedia e veterinaria per interventi di artroprotesi, che comprende almeno un primo componente (11) e un secondo componente (12) che si coniugano attraverso un primo accoppiamento conico (15, 21) e un secondo accoppiamento conico (23, 26) coassiale e di conicità opposta a quella del primo accoppiamento conico. Il secondo accoppiamento conico è formato da una sede conica (23) ricavata nel secondo componente (12) di protesi, da un controcono (13) applicato e spostabile assialmente sul primo componente (11), e da una controvite di bloccaggio (14) avvitata al primo componente ed interagente assialmente con detto controcono (13) per immobilizzarlo nella sede conica.Fig. 2.
