Abstract

Elemento de anclaje (1) para equipo de osteosíntesis vertebral, que comprende una base de anclaje (2) que incluye una pared proximal periférica (5) que delimita hacia el interior una cavidad proximal, y un clavo proximal (3) que incluye una parte de articulación distal (7) recibida en dicha cavidad proximal, dicha pared proximal (5) que incluye un borde proximal periférico (6) orientado hacia el eje de dicha cavidad proximal, lo que asegura la retención de dicha parte de articulación distal (7) en esa cavidad proximal; dicha cavidad proximal tiene un eje, dicha pared proximal tiene una superficie interna en el lado de dicha cavidad proximal, y dicho clavo proximal tiene un eje longitudinal; caracterizado por el hecho de que - la parte de articulación distal (7) tiene un borde periférico dimensionado para entrar en la proximidad inmediata de la superficie interna de dicha pared proximal (5), y tiene una superficie distal convexa (9) con un vértice, dicho vértice situado sustancialmente en el eje del clavo proximal (3); y - el elemento de anclaje (1) comprende un elemento elásticamente deformable (10) colocado en el fondo de dicha cavidad proximal, con una forma curvada y un vértice, donde dicho vértice de dicho elemento elásticamente deformable está situado sustancialmente en el eje de dicha cavidad proximal, donde dicha superficie distal convexa (9) se apoya contra dicho elemento elásticamente deformable (10), y donde el último está elásticamente deformado de forma permanente de manera que presiona continuamente dicha parte de articulación distal (7) contra dicho borde proximal periférico (6) para generar una fricción entre dicha parte de articulación distal (7) y dicho borde proximal periférico (6) capaz de mantener el clavo proximal (3) en una posición predeterminada sin impedir que el clavo se mueva a otra posición.
