Patent AT-E400227-T1: [Translated] DEVICE FOR OSTEOSYNTHESIS

Osteosynthesis device, particularly for the spine by means of internal implantation, comprising firstly one or more bars (2) used to support or move the spine, and secondly at least one implant (3) connecting the bars and the vertebrae, said implant comprising firstly bone anchorage means attached to the body of said implant and secondly fixation means for said bars, said fixation being carried out by clamping means (31) clamping said bar against the internal walls (320) of a channel (32), with an opening, formed in said body of the implant (3), characterised in that said bars comprise a transversal bearing surface (21) on at least part of their length, said transversal bearing surface being produced by a cross-section of said bars comprising at least one part of lower or opposed convexity in relation to the rest of said cross-section, and in that the axis of the clamping means is merged with or parallel to the symmetrical axis of the bone anchorage means of the body, and the clamping means comprise a surface (310) which is adapted to the transversal bearing surface (21) of the bar (2),the contact surface, between the bar and surface (310) of the clamping means or the internal wall (320) of the channel (32), being adapted to allow to carry out a rotation or transversal shift of the bar to adjust the transversal position and the angular position of this bar on the body.
