Abstract
Dispositivo de anclaje de hueso poliaxial, que incluye un elemento de anclaje (1) que tiene un vástago (2) para anclarlo en el hueso y una cabeza (3), una pieza receptora (5, 5') para recibir y alojar la cabeza del elemento de anclaje de hueso y para recibir una varilla (100), incluyendo la pieza receptora un elemento superior (8, 8') con un extremo superior (81) y un extremo inferior (82), un eje central (C) que se extiende a través del extremo superior y del extremo inferior, una parte receptora de cabeza (84) con un paso (85) en el extremo inferior (82) para introducir la cabeza y un canal (86) para recibir la varilla en el extremo superior (81); un elemento inferior (10, 10') que tiene un extremo superior (101) y un extremo inferior (102) y un paso (103, 104) que se extiende desde el extremo superior hasta el extremo inferior, pudiendo conectarse el elemento inferior con el elemento superior desde el extremo inferior (82) del elemento superior; estando previsto al menos un elemento de inmovilización (20, 200) en el extremo inferior (82) del elemento superior o cerca del mismo, caracterizado porque al menos un elemento de inmovilización (20, 200) sobresale dentro del paso (85) de la parte receptora de cabeza (84) del elemento superior (8, 8') cuando el elemento inferior está conectado con el elemento superior para sujetar la cabeza (3) cuando ésta es insertada en la parte receptora de cabeza (84).
Description
En lugar de las bolas o el anillo de inmovilización también se pueden concebir otros dispositivos de inmovilización, como por ejemplo elementos de muelle que se puedan comprimir mientras se introduce la cabeza y que, cuando la cabeza los ha pasado, se pueden expandir y sujetar la cabeza en su lugar.
5 El contorno exterior del elemento superior y el elemento inferior no está limitado al contorno exterior mostrado en las realizaciones. Además, en lugar de la conexión roscada entre el elemento superior y el elemento inferior, también es posible una conexión por ajuste a presión o cualquier otra conexión que permita fijar el elemento inferior al elemento superior. La pieza receptora también puede tener un diseño que permita girar el elemento de anclaje de hueso en un mayor ángulo hacia un lado que hacia el otro lado.
10 El elemento de bloqueo no está limitado al tornillo interior mostrado en las realizaciones. También se puede concebir cualquier tipo de elemento de bloqueo o combinación de elementos de bloqueo, como un elemento de bloqueo en dos piezas. Además, el elemento de presión no se limita a la forma específica mostrada en las realizaciones. Por ejemplo, en lugar de un entrante cilíndrico, el elemento de presión puede tener un entrante
15 en forma de U que proporcione un canal para la varilla con brazos que se extienden por encima de la varilla, de modo que se puede utilizar un dispositivo de bloqueo correspondiente que permita fijar independientemente la cabeza y la varilla.
El elemento de anclaje de hueso puede ser cualquier elemento de anclaje de hueso adecuado, como un
20 tornillo para hueso, un clavo para hueso, un anclaje de hueso con barbas, un elemento de anclaje de hueso canulado, etc.
