Abstract
A connector (1) for a spinal osteosynthesis device, for connecting two rods to a plate fixed in a vertebra, includes a first orifice (2) opening onto two opposed faces (3, 4) of the connector (1), and two other orifices (5, 6) opening onto two other opposed faces (7, 8) of the connector (1). Each of the two other orifices (5, 6) are each designed to receive a rod (14, 15) of the osteosynthesis device. The connector (1) includes a mechanism making it possible, when the connector (1) is push-fitted onto a protrusion (100) of a bone anchor member, to tighten the rods (14, 15) simultaneously in the two other orifices (5, 6) when a nut (22) is screwed onto the protrusion (100). An assembly for spinal osteosynthesis device includes a plate (16) that includes a protrusion (100), a connector (1) as previously described, and a nut (22).
