Patent ID: 8083778

Claim:
A vertebral osteosynthesis equipment, comprising: bony anchoring members, of which at least one includes a proximal threaded stud ( 6 ); 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; a connecting part ( 3 ) for connecting the linking rod(s) ( 2 ) to said bony anchoring member; 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 ); a hole ( 31 ) of the distal branch ( 21 ) of the connecting part ( 3 ), such that the closest of the vertebrae after implantation, is adapted to receive a tubular screw ( 5 ) that can be screwed therein; and a first fastening nut( 4 ) intended to be tightened on the proximal threaded stud ( 6 ) for assembling the connecting part ( 3 ) thereon, the tubular screw ( 5 ) being adapted to be screwed in the hole ( 31 ) of the distal branch ( 21 ) and having a head adapted to rest on the proximal branch ( 22 ), said tubular screw ( 5 ) forming an axial bore with a diameter greater than that of the proximal threaded stud ( 6 ), the connecting part ( 3 ) equipped with said tubular screw ( 5 ) is adapted to be engaged on the proximal threaded stud ( 6 ) of said at least one bony anchoring member, coaxially with said first fastening nut ( 4 ), and said tubular screw ( 5 ) is adapted to be tightened for clamping both branches ( 21 , 22 ), and said first fastening nut ( 4 ) is adapted to rest against said head of said tubular screw ( 5 ), for assembly of the connecting part ( 3 ) on the proximal threaded stud ( 6 ).
