Bone junction device for elastic deformation possible vertebral column

摘要

(57) Abstract This bone junction device as two anchor components which are locked in two vertebrae (4) (2) and the anchor component is concatenated mutually, has with the connected component (6,106) which gives stress vis-a-vis the straight advancing motion where the anchor component faces mutually. Elasticity it can deform the connected component (6,106) vis-a-vis the bend around the deformation shaft center (45,47,49). The connected component has two fixed parts (16) and the intermediate section (40) which are locked in two anchor components (2). The intermediate section has done from the alignment shaft center (18) of two fixed parts (16) the offset. The connected component (6,106) mutually this has two this connection sections (39) which touch at the time of the deformation around the deformation shaft center.
