Patent ID: 7763054

Claim:
A vertebral osteosynthesis equipment, comprising: bony anchoring members; one or two linking rods ( 2 ), intended to be connected to the bony anchoring members and to be attached to the vertebrae by dint thereof; and a connecting part ( 3 ) for connecting the linking rod(s) ( 2 ) to the bony anchoring members, at least one bony anchoring member including a proximal threaded stud ( 6 ) and a first fastening nut ( 4 ) intended to be screwed on the proximal threaded stud ( 6 ) for assembling the connecting part ( 3 ) thereon, and the connecting part ( 3 ) including a second fastening nut ( 5 ) engaged on the proximal threaded stud ( 6 ) of said at least one bony anchoring member coaxially with said first fastening nut ( 4 ), wherein said connecting part ( 3 ) comprises a rounded section ( 20 ) intended for hugging the linking rod ( 2 ) and two parallel distal and proximal branches ( 21 , 22 ) drilled with holes for engagement on the proximal threaded stud ( 6 ) of said at least one bony anchoring member ( 1 ), the two parallel distal and proximal branches ( 21 , 22 ) being laid out for being clamped in order to clamp said rounded section ( 20 ) around the at least one linking rod ( 2 ), said second fastening nut ( 5 ) has threaded means enabling to clamp the two parallel distal and proximal branches ( 21 , 22 ) of the connecting part ( 3 ) so as to immobilize the linking rod ( 2 ) with respect to the connecting part ( 3 ), said distal branch of the connector includes a proximal face opposite the proximal branch and said first fastening nut being introduced in the hole of the proximal branch until reaching and resting directly on the proximal face of the distal branch, said second fastening nut resting directly on the proximal branch of the connector, said first and second fastening nuts are separated elements, and said first fastening nut is completely tightened when bearing on the distal branch.
