Abstract

La invención se refiere a un dispositivo para remplazar huesos vertebrales, la cual consta de un cuerpo hueco interior (1) y de un cuerpo hueco exterior (2). Estos cuerpos huecos (1, 2) pueden deslizar coaxialmente en el interior del otro a lo largo de un eje central (3) y pueden moverse relativamente con relación al otro en la dirección del eje central (3). El cuerpo hueco interior (1) está provisto de un mecanismo de captura (5) en su superficie externa (4). La invención se caracteriza porque el cuerpo hueco exterior (2) tiene taladrado todo el recorrido a lo largo de su eje central (3) y el cuerpo externo hueco (2) tiene al menos un elemento elástico (7). El mencionado elemento elástico sobresale dentro del taladro (10) en su extremo superior (9). Esto reduce el diámetro del mencionado taladro (10) de tal forma que el elemento elástico (7) se engancha en el mecanismo de enganche (5) del cuerpo hueco interior (1), fijando de este modo la longitud del dispositivo de tal forma que sea resistente a la compresión.
