  • Patent number: 5385583
    Abstract: The implant comprises a part (2) for anchorage in the bone and a body (3) for fixing on a rod (4), the body comprising two lateral branches (5) defining a passageway (6) which is open on each side of the body for receiving the rod, and a screw-threaded plug (8) adapted to be screwed between the branches; a strip (14), interposed between the plug and the rod, is fixed to a ring (15) with which it constitutes a pellet (16). The strip (14) is curved and defines a concave surface (14a) adapted to be applied against the surface of the rod. The curvature of the strip (14) permits clamping the rod (4) in position with a relatively small clamping pressure in that the forces are distributed, which improves resistance to alternating bending of the rod in the body (3) and resistance to fatigue.

  • Patent number: 5067955
    Abstract: This vertebral implant (1) comprises an osseous anchoring element (2), a body (3) having a channel (4) designed to be passed through by a rod (5), and a first screw (9) for securing with the rod, screwed through a clamp (20) able to slide on the rod and to take up a position in the body; this implant comprises at least one second screw (12, 13) for blocking the rod (5), passing through the body (3) laterally to the first screw (9) and engaged in a tapped hole (12a, 13a) inclined relative to the axis (XX) of the said first screw, these two screws (9, 12 or 13) being situated essentially in a phane perpendicular to the axis (YY) of the channel (4) and of the rod (5). The size of this implant is smaller than that of the known clamp and lock implants, and it can be put into position more easily and more quickly by the surgeon.
