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

摘要

Clamp (1) that can advantageously be applied to both temporary and definitive orthopaedic external fixation systems comprising: - a first coupling element (2), comprising a pair of opposite jaws (3, 4) together defining one or more seats able to house at least a first component of the orthopaedic external fixation system; - a second coupling element (8), comprising a pair of opposite jaws (9, 10) together defining one or more seats able to house at least a second component of the orthopaedic external fixation system; - an interconnection pin (7) passing through and connecting the first (2) and second (8) coupling elements along a main axis of rotation (x); - fastening means arranged to bring the clamp (1) from a slack configuration, wherein the first (2) and second coupling elements (8) are relatively rotatable at least along the main axis of rotation (x), to a locked configuration, wherein the first (2) and second coupling elements (8) are relatively rotatable with each other; these fastening means dividing in - temporary fastening means, which can be manually operated, to temporarily lock the clamp (1); - definitive fastening means, which can be operated by means of a fastening tool, to definitively lock the clamp (1).
