Patent attributes
A set of surgical instruments for the fusion of vertebrae contains supporting elements that have a threaded stem that can be screwed into the vertebra and a head part positioned at the outer end of the threaded stem. A connection unit is fitted between the supporting elements and a fixating device serving to brace together the supporting elements and the connection unit, and the head part of the supporting element has an accepting opening suitable for joining the connecting unit. The accepting opening is formed by the unification of an introductory cleft running from the outer surface of the head part and penetrating into the head part, and a lead-through seat that forms the continuation of the introductory cleft, is worked into the head part and bells out from there. The head part has a fusion opening that has a first connection piece and ends in the lead-through seat, and the fixating device has a tightening body that is positioned in the fusion opening so that it may move. A second connecting piece operates in unison with the first connecting piece, and the connecting unit is assembled from the group of the elemental connection strands penetrating the introductory cleft of the head part.
