Clamp for temporary or definitive external orthopaedic fixation, and external fixation system comprising said clamp

An orthopaedic external fixation system comprising a clamp for an orthopaedic external fixation system comprising:

• a first coupling element, comprising a pair of opposite jaws together defining one or more seats able to house at least a first component of the orthopaedic external fixation system;
• a second coupling element, comprising a pair of opposite jaws together defining one or more seats able to house at least a second component of the orthopaedic external fixation system;
• an interconnection pin that passes through and connects the first and second coupling elements along a main axis of rotation;
• fastening means arranged to bring the clamp from a slack configuration, in which the first and second coupling elements are relatively rotatable at least along the main axis of rotation, to a locked configuration, in which the first and second coupling elements are relatively integral with each other;
• wherein said fastening means comprise:
• temporary fastening means, manually operable, arranged to temporarily bring the clamp in the locked configuration;
• definitive fastening means, operable by means of a fastening tool, arranged to definitively bring the clamp in the locked configuration, and
• comprising at least a wire-carrier element, arranged to allow at least a Kirschner wire or other fixator of limited diameter to be fixed to a system clamp,
• wherein said wire-carrier element comprises a shank with a threaded portion whereon a fastening plate is screwed until it abuts against an abutting plate that is integral with the shank.
