Abstract:
A device for relocating a lower jaw relative to an upper jaw, the device comprising:a first sleeve with a first holder mounted on its one end; a second sleeve having an internal thread in one of the two sleeves and a matching external thread on the other sleeve, by means of which they are screwed together over a variable length; a third sleeve having an end facing the first holder mounted on the second sleeve a rod arranged in the third sleeve for longitudinal displacement; a second holder, which is mounted outside the third sleeve on an end of the rod which faces away from the first holder; and a stop provided on the rod, on or in the neighborhood of the second holder, and abutting directly or indirectly against the end of the third sleeve which faces away from the first holder and toward the second holder, a length of the rod being selected to ensure that in an abutting position the rod will extend into the first sleeve; said third sleeve being adapted to dampen impacts that act in a longitudinal direction, by compression of the third sleeve between said ends, as the rod moves within said third sleeve.
