Occipital plate for occipito-cervical fixation and system for occipito-cervical fixation

A system for occipito-cervical fixation, comprising:

• a substantially flat plate provided with at least one fixation area connectable to the skull of a patient and at least one pair of through slots set at a distance from the fixation area and extending length-wise away from each other;
• at least one pair of clamps, wherein each clamp of the pair of claims is slidably constrained in a respective through slot to move along a medial-lateral adjustment direction and provided with respective receiving seats for receiving a support bar, wherein each receiving seat has an insertion opening for insertion of the respective support bar accessible laterally and longitudinally along respective insertion directions substantially parallel to a lying plane of the substantially flat plate;
• at least two joining screws inserted in the fixation area and perpendicular to said lying plane of the substantially flat plate for connection to the skull of a patient;
• a pair of longitudinal support bars, each having an end portion inserted in a corresponding receiving seat of a clamp of the pair of clamps;
• wherein the receiving seat of each clamp of the pair of clamps has an elastic retaining means configured to provisionally keep the respective support bar inside the receiving seat once inserted;
• wherein each clamp of the pair of clamps comprises a clamping member associated with the receiving seat and configured to lock the position of the respective support bar in receiving the seat;
• wherein each clamp of the pair of clamps is also rotatably coupled to the respective through slot so as to rotate about a respective axis parallel the at least two joining screws.
