Abstract: The invention concerns a bone fixing device (1) for immobilizing a linking rod (2) designed to connect at least one bone fragment (3) to another, said device comprising: at least one anchoring means (4) designed to be fixed on or in said bone fragment (3); at least one receiving part (7), secured to said anchoring means (4), designed to receive at least part of said linking rod (2); locking means (8) designed to lock said part of the linking rod (2) within said receiving part (7). The invention is characterized in that said locking means comprise at least one solid element (8) having a longitudinal axis, said solid element including at least one inclined surface (9) capable, under the action of a thrust directed along the longitudinal axis of said solid element, of gradually wedging by friction said part of the linking rod (2) into said receiving part (7), until said part of the linking rod (2) is completely locked inside said receiving part (7).

Abstract: The invention concerns an implantable device for fixing a rod in a rather thin bone wall comprising two parts, each comprising a body with a passage for receiving the rod, and a curved hook extending laterally relative to the body. Each hook is shaped such that the two hooks facing each other can be simultaneously inserted, by mutually titling the two parts urging their bodies closer to each other, in an opening arranged in the wall, and be mutually spaced rearwards as said bodies are brought closer to each other. The rod received in said passages of the two bodies is capable of preventing any reverse tilting of said parts. The invention is particularly useful for fixing a rod for backbone osteosynthesis in the flat part of the skull occipital bone.
