Abstract
This invention relates to a prosthetic element comprising two principal components intended to be assembled together and immobilized with respect to each other by means of a screw, which may be screwed by means of at least one thread in two tappings which are respectively fast or intended to be rendered fast with one and the other principal components. The screw comprises at least one radial element in relief adapted to come into abutment against a stop surface fast with a first component, and a non-threaded end forming guide finger and adapted to slide in a housing, of cross-section correspondiong to that of this finger and made in the second component.

Prosthetic element comprising a first and a second principal components intended to be assembled together and immobilized with respect to each other by means of a screw,
- wherein said screw is adapted to be screwed by means of at least one thread in two tappings which are respectively fast or intended to be rendered fast with one and the other principal components, said screw comprises at least one radial element in relief adapted to come into abutment against a stop surface fast with said first component, and a non-threaded end forming guide finger and adapted to slide in a housing made in said second component.
Process for assembling a prosthetic element comprising two principal components and a screw,
- wherein it comprises the steps consisting in:
- immobilizing said screw with respect to a first principal component by screwing said screw in a first tapping fast or intended to be rendered fast with said first principal component, a surface forming stop, at a distance from said screw with respect to said first component, being arranged around said screw after or before this immobilization;
- covering with a housing made on said second component, a free end of said screw projecting with respect to said first component;
- pushing said first and second components towards each other, causing said end of said screw to slide in said housing;
- unscrewing said screw with respect to said first tapping, and
- screwing said screw in a second tapping made in said second component, exerting on said stop surface an effort of approach of said first and second components.
Process for assembling of a prosthetic element comprising two principal components and a screw,
- wherein it comprises the steps consisting in:
- immobilizing said screw with respect to a first principal component by screwing said screw in a first tapping fast or intended to be rendered fast with said first principal component, a surface forming stop at a distance from said screw with respect to said first component being disposed around said screw after or before this immobilization;
- covering, with a housing made on said second component, a free end of said screw projecting with respect to said first component,
- impacting one of said principal components in the direction of the other so as to bring them closer, causing said free end to slide in said housing, until said components are brought into contact with each other;
- unscrewing said screw with respect to said first tapping, and
- screwing said screw in a second tapping made in said second component until an effort of relative immobilization of said components is obtained in their position in contact, said effort being exerted on said stop surface.
