Abstract:
A multiaxial connector for producing a spinal implant (A) to keep a connecting rod (2) in determined angular positions with respect to the vertebral bodies (B), said connector (1) being fixed to each vertebral body (B) by a fixing screw (3) comprising a first threaded part (6) for anchoring it into the bone tissue, an intermediate head (7) of hexagonal profile and a second threaded part (8) that takes a clamping nut (9), characterized in that it comprises:a first connecting element (4) pierced with a bore (10) designed to receive the second threaded part (8) of the fixing screw (3), with another bore (13), comprising, in its interior part, an annular track (14) of spherical profile, and with a slot (16) passing through the bore (10) to open into the bore (13) at the annular track (14); a second connecting element (5) pierced with a bore (20) designed to receive the connecting rod (2), with a threaded hole (21) collaborating with a binding screw (22) for immobilizing said rod in terms of translation; and connecting means (15) forming a ball joint which, on the one hand, allow the first and second connecting elements (4, 5) to be coupled to one another in such a way that said elements can pivot one with respect to the other so as to present the connecting rod (2) in determined angular positions and, on the other hand, allow the connecting rod (2) to be offset laterally with respect to the center of pivoting of said elements (4, 5).
