  • Each support plate has on its outwardly facing side a contact surface with which the support plate is supported on a vortex adjacent to the disc space.
  • On the inside of each support plate is a hinge part, which is formed in one support plate by a dome-shaped socket and the other support plate by a corresponding dome-shaped joint head. When inserted, the socket and the condyle together form a ball joint, so that the two support plates can be tilted in all spatial directions relative to each other.

  • the two legs can each be inserted in an orientation in which the locking element with its narrower transverse direction through the gap between the support plates passes through, then rotated by 90 ° in the locked position and connected to each other.
  • the legs preferably have a substantially round profile over their insertable length, and the locking elements are in each case designed as rigid extensions formed in a T-shaped manner on the end of the legs.
  • the blocking elements should expediently be shaped in such a way that in the locked position they can not transmit any force component which spreads apart the carrier plates, which makes it difficult to drive the intervertebral disc prosthesis out of the intervertebral disc space.
  • the extraction means may advantageously comprise a shank with a stop and a return weight movable along the shank as far as the stop.
  • the disc prosthesis can then be careful in small
  • Steps are driven by the kickback weight by the operator jerky moves against the stop - -

  • Joint socket 5 and condyle 6 together form a ball joint, so that the two support plates 3, 4 of the intervertebral disc prosthesis 10 can be tilted in all spatial directions to each other.
  • FIG. 2 An inventive extractor 20 is shown in Figure 2 above the lower support plate 4 of the disc prosthesis 10 schematically in a plan view and in Figure 5 in an exploded view.

Abstract

Extracteur chirurgical (20) servant à extraire par opération des prothèses de disques intervertébraux qui comprennent deux plaques de support (3, 4) pourvues chacune d'une partie d'articulation (5, 6). Ledit extracteur (20) possède deux bras (21, 21') reliés l'un à l'autre en forme de fourche, qui peuvent être introduits dans un espace intermédiaire situé entre les plaques de support (3, 4) et qui portent à leur extrémité libre chacun au moins un élément de blocage (22, 22'). Dans une première position, ledit élément de blocage permet l'introduction des bras dans l'espace intermédiaire situé entre les deux plaques de support (3, 4) et dans une seconde position, de blocage, il dépasse de l'espace intermédiaire dans le sens vertical. Les deux bras (21, 21') sont reliés à un moyen d'extraction commun (24, 25, 26) pour la transmission d'une force de traction sur les bras (21, 21') dans le sens longitudinal de ces derniers.
