Patent ID: 8096991

Claim:
A medical device suitable for fixing bone parts, comprising a rigid outer tube, which is provided with at least two opposed recesses near the first end positioned in the bone, an inner tube that can be accommodated in the rigid outer tube, which inner tube is provided with at least two strips extending in the longitudinal direction of the inner tube on the side that is positioned in the bone, as well as means for loading the inner tube in axial direction, in such a manner that a pressure force exerted on said strips causes the strips to bend outwards through the aforesaid recesses, which means for loading the inner tube in axial direction are made up of a screw that fits in another end of the outer tube that is positioned in the bone, which screw mates with a screw thread present on the inner wall of the outer tube, wherein the first end of the outer tube that is positioned in the bone is arranged to exert a pressure force on the outwardly bending strips by suitably turning the screw, characterised in that the connection between the outer tube and the inner tube is formed by an annular wire, which is accommodated in corresponding grooves formed in the inner wall of the outer tube and the outer wall of the inner tube.
