Abstract: A fixing device is for a surgical anchor member. The fixing device may include a control component joined to a connecting portion, which is in turn connected to a shaft provided at one end with coupling units for connecting the fixing device to a fastening element suitable to couple with a respective fastening seat of a surgical anchor element. The fixing device may include a centering component for the coupling of the fastening member with the respective fastening seat of the surgical anchor member.

Abstract: A polyaxial screw for surgical implant comprising an axially hollow central body; an anchoring element having an anchoring portion and a coupling portion, said anchoring portion projecting from said central body and said coupling portion being received inside the axial cavity of said central body; an insert axially received inside said axial cavity of the central body and an attachment element suitable to couple internally to said central body, characterized in that said insert has an elastic portion able to apply to at least a portion of the anchoring element a distributed compression load the resultant force of which being directed along the central axis X.

Abstract: A device is for fixing surgical implants in place. The device may include a central body having an axially hollow upper zone, and an axially hollow lower zone. The upper and lower zones may form a single body being open at the bottom and at the top. A central through cavity may extend inside the upper and lower zones. The upper zone may have two portions projecting axially from the upper zone, divided from each other by two through U-shaped slots and forming, in conjunction with part of the central cavity, a channel for housing a connection rod. The lower zone may include a slot for the lateral access to the central cavity of an anchoring device. The slot may be in a conformation such as to permit the lateral insertion of the anchoring device inside the central cavity.
