Intervertebral implant for mutual situating of adjacent vertebrae contains a cover (1) in a shape close to the rectangle, in which is fixed a driving mechanism. In a lateral wall (2) of the cover (1) a manipulative hole (3) is made. The cover (1) is equipped with one open seat (4). The driving mechanism composes situated in the seat 4 and anchoring in one of displaced vertebrae one rotational element (5) with an axis 6 mounted for an axial movement in lateral walls (2) of the cover (1) perpendicularly to the direction of the displacement of vertebrae against each other, cooperating with the connecting element (7). The rotational element (5) is equipped with anchoring latches 8 projecting over the height of cover's (1) walls (2) from the side contacting with one of displaced vertebrae and anchoring in this vertebrae. Anchoring latches (8) have got a form of paddles of equal dimensions and shapes. The connecting element (7), situated within the diameter of the manipulative hole (3) of the cover (1), cooperates with not visible on the figure separate driving tool. The connecting element (7) constitutes one shaped end of the axis (6) of the rotational element (5). The implant is equipped with two blockades of the rotation of the driving element. One of blockades of the driving mechanism has got a form of a pin (9a) situated within the diameter of the manipulative hole (3) of the cover (1) and cooperating with not visible on this figure recess in the axis (6) of the rotational element (5), whereas the second blockade of the rotation constitutes a latch 9b fixed to the cover (1) on the opposite side than the pin (9a), cooperating with the rotational element (5). The lower surface of one of lateral walls (2) of the cover (1) is equipped with anchoring latches (10) in a form of paddles, anchoring in the second of displaced vertebrae. |
