Definitions

  • the invention concerns a distracting device for widening or extending a person's jaw by gradually moving two opposite bone parts of the jaw in relation to one another, whereby this device comprises two fixing elements which must each be fixed to one of said bone parts, whereby these fixing elements have means for fixing at least one expansion element which must extend between said fixing elements so as to connect the latter to each other.
  • the invention is characterised in that said expansion element is made relatively rigid and has two parts which are hinge-mounted to each other.
  • said parts of the expansion element are connected to each other via a cardan hinge.
  • the far ends of said expansion element are threaded in the opposite sense, whereby these far ends can be fit in corresponding recesses in said fixing elements such that, by subjecting said expansion element to a rotation, the fixing elements are moved in relation to each other.
  • the distracting device comprises two expansion elements.
  • the invention also concerns an expansion element for a distracting device for widening or extending a person's jaw by gradually moving two opposite bone parts of the jaw in relation to one another, whereby this expansion element has two rigid bar-shaped parts which are connected to each other at one of their far ends by means of a hinge point.
  • said hinge point is formed of a cardan hinge.
  • Figure 1 is a schematic front view of the frontal part of a lower jaw, provided with a distracting device according to a first embodiment of the invention.

  • This lower jaw 1 has been surgically divided in two parts 2 and 3, whereby subsequently, by means of the illustrated distracting device, these two bone parts 2 and 3 are gradually moved away from each other.
  • This distracting device comprises two fixing elements 4 and 5 which are each fixed to one of said bone parts 4 and 5 by means of screws 6. Between these fixing elements 4 and 5 extend two expansion elements 9 and 10. Further, on the far end opposite the one that is fixed to the jaw, these fixing elements 4 and 5 have two recesses in the shape of cylindrical bore holes 7 and 8 in which is provided internal screw thread.

Abstract

L'invention concerne un dispositif d'écartement permettant d'élargir ou d'étendre la mâchoire d'une personne par déplacement graduel, l'une par rapport à l'autre, de deux parties osseuses opposées de la mâchoire. Ce dispositif comprend deux éléments de fixation à fixer respectivement à une partie osseuse. Ces éléments de fixation ont des moyens à fixer à au moins un élément d'expansion qui doit s'étendre entre ces éléments de fixation de manière à connecter ces derniers l'un à l'autre. L'invention est caractérisée en ce que cet élément d'expansion est relativement rigide et a deux parties articulées l'une à l'autre.
