Implantable treatment device fixed or interlinked to bone
The invention relates to an implantable device fixed or interlinked to bone, which generates unidirectional movement by a member generating reciprocating motion in the same direction using means allowing unidirectional movement. In the device, the means allowing unidirectional movement comprise means based on friction which make line contact.
The invention relates to an internal osteodistraction device, which includes two fixing points (7, 8) for attachment to a bone in such a way that the distance between the fixing points can be increased in a controlled manner, and a magnetostrictive element (1) which produces a reciprocating mechanical motion in a changing magnetic field. The magnetostrictive element is configured for taking up solely a compressive or tensile force, such that the magnetostrictive element pushes a unidirectional movement permitting element which allows for an increase in the distance between the fixing points, and as the magnetostrictive element is in the process of returning to its original length, a second unidirectional movement permitting element allows the magnetostrictive element to resume its original length without changing a distance between the fixing points of the distraction device.
