  • Patent number: 8414618
    Abstract: A vertebral column implant for the elastic stabilization of motion segments including an elastically bendable connecting element which can be passed through the seats of a number of pedicle screws having offset seat axes and be anchored. The connecting element is bendable elastically about every axis of its cross-section in such a way that the connecting element can be passed through, or inserted in, the seats of the screwheads, one behind the other, even when the seats are not situated on one and the same axis.

  • Publication number: 20120253400
    Abstract: A vertebral column implant for stabilizing and stiffening of vertebral bodies of a vertebral column comprises at least one first and at least one second bone screw, which is screwable into a vertebral body. A first rigid connecting element is insertable into first receiving means of the first bone screw. A second elastic connecting element is insertable into second receiving means of the second bone screw. The connecting means are installed on a further bone screw and comprise a first and second clamping device for respectively holding tightly the first and second connecting element. The first clamping device has a U-shaped receiving part for the end region of the first connecting element, which is designed spherical, a clamping means being placeable on the U-shaped receiving part, with which clamping means the spherical end region is able to be clamped against the bottom surface of the U-shaped receiving part.

  • Publication number: 20120253401
    Abstract: A vertebral column implant for stabilizing and stiffening of vertebral bodies of a vertebral column comprises at least one first bone screw, screwable into a vertebral body, and at least one second bone screw. A first rigid connecting element, is insertable into first receiving means of the first bone screw. A second elastic connecting element, is insertable into second receiving means of the second bone screw. The connecting means comprise two arms, which form a U-shaped recess. Insertable into a first region of the U-shaped recess is an end region of a first connecting element. Insertable into a second region of the U-shaped recess is an end region of a second connecting element. Inserted between the two arms is a pressing element. Placed on the arms and are clamping means, with which the pressing element is pressed against two end regions of the first and second connecting elements.

  • Patent number: 8221469
    Abstract: A pedicle screw with a closure device for securing a rod for stabilization of the vertebral column comprises a screw-in part with a head part, a U-shaped recess in the head part., in which recess the rod is held by the closure device. The closure device comprises a yoke-shaped locking element, which has a collar with a projection on each of the two opposite end regions. One groove is provided on each of the two arms in such a way that the locking element is rotatably placed on the arms. The projections are inserted in the grooves to achieve locking position. A tension screw is screwed into the locking element and rotatably connected to a tension element inserted between the arms, and, in the locked state of the locking element, is able to be tensioned, by means of the tension screw, against the rod inserted in the recess.

  • Patent number: 8202303
    Abstract: Pedicle screws with a closure device for receiving and securing a rod made up of a flexible plastic, for stabilization of a vertebral column. The pedicle screws include a screw-in part, a head part with a U-shaped recess formed by two arms and into which the rod to be held is insertable. The U-shaped recess is closable by a locking element. A clamping screw, put into the locking element, presses an insert on the rod and clamps the latter between a first clamping surface and a second clamping surface. The insert is provided with stop faces by which the clamping action against the rod, transmitted to the insert by the clamping screw during the clamping step, is limited. An optimal connection between rod and pedicle screw is thereby obtained.

  • Patent number: 8162986
    Abstract: A vertebral column implant includes a connecting element, which is insertable in the vertebral bodies of a vertebral column via several bone screws. The screws are each provided with a head part for receiving the connecting element, by means of which a firm connection is achievable between bone screws and connecting element. The connecting element is composed of rigid sections and elastic sections. The rigid sections are connectable to the elastic sections via connecting devices. The connecting devices are designed such that the rigid sections and the elastic sections, in each case connected to one another, are aligned substantially coaxially, and their connection is form-fitting.

  • Patent number: 8075598
    Abstract: A pedicle screw with a closure device (16) for securing a rod (10) for stabilization of the vertebral column comprises a screw-in part (2), a head part (3) provided on the screw-in part (2), and a U-shaped recess (4) disposed in the head part (3), which recess is formed by the inner surfaces (5, 6) of two arms (7, 8) and a bottom surface (9) connecting the two inner surfaces. The rod (10) is insertable into this recess, and is held by the closure device (16). The rod (10) is provided with ridges (12) and grooves (13) running transversely with respect to the rod axis (11). Likewise provided with corresponding ridges (14) and grooves (15) is the bottom surface (9). The closure device (16) comprises a support element (17), which is insertable between the two arms (7, 8).

  • Patent number: 7597707
    Abstract: A pedicle screw with a closure device including a seat element and a closure cap for quick closure of the seat element of the pedicle screw. An elastic rod element inserted therein in the seat recess, which element serves to stabilize a vertebral column, is held in a form-locking way. The closure cap of the closure device has the function of a cross-brace, and can transfer the forces absorbed by it from the rod element to the pedicle screw. Disposed on the closure cap with a holding recess are engagement elements which, during insertion of the closure cap, automatically lock in place in a stable position in the seat element provided with a U-shaped seat recess. The seat recess and the holding recess preferably have a ridged or grooved structure corresponding to the rod element used.
