Abstract: The immobilization device for a connecting rod (2) in an osseous anchoring element (3) of a rachidian implant (4) comprises an osseous anchoring implant (3) comprising retaining means (14, 15) adapted to deform elastically under a pressure force F and a blocking element (5) comprising on the one hand lugs (33, 34) which coact with the retaining means (14, 15) to permit the securement of the blocking element (5) on the osseous anchoring element (3), and on the other hand, a tightening screw (31) permitting immobilizing in rotation and in translation the connecting rod (2) between the osseous anchoring element (3) and the blocking element (5).

Abstract: A vertebral anchoring device including a polyaxial anchoring screw having a spherical head; a connecting rod; a connection element for receiving portions of the connecting rod; a clip having a pressure screw positionable to engage the connecting rod; and a connector installable on the spherical head for receiving the connecting rod. The connector includes a socket and a ring which co-act with one other about the spherical head of the screw in an installed orientation. The socket includes two portions bridged together at an upper level of the socket so that the two portions are positionable in a spaced apart orientation to enable the socket to be installed on the spherical head. Pressure of the pressure screw against the connecting rod bears the connecting rod against the ring which bears the ring against the spherical head of the screw.

Abstract: A surgical instrument includes: grip handles (2, 3) which are articulated to each other around a fulcrum pin (4) so that the jaws can be moved from an open position to a closed position; and connecting elements (5) which can be used to: (i) lock the handles (2, 3) in a determined, constant position when a first force is exerted on the handles; and (ii) unlock the handles (2, 3) when a second force is exerted on same.
