<p>A clamp (1; l'; 1") for orthopaedic external fixator (100), practical and safe to use, comprises: a first attachment (2), provided with a pair of arms respectively internal (22) and external (21) defining one with the other a lateral housing (20) with C-shaped section for housing a first connection bar (101) and comprising a mobile jaw (5) hinged on its external arm (21); a second attachment (3; 3'; 3") for allowing the connection of the clamp (1; l'; 1") to a second component (102; 102') of the orthopaedic external fixator (100); a tightening element (4), at least partially threaded, which traverses and connects the first and the second attachment (2, 3; 3'; 3") along an axis of rotation (x) and whereto the mobile jaw (5) is subjected, the tightening of the tightening element (4) bringing the clamp from a loosened configuration, at which the two attachments (2, 3; 3'; 3") are reciprocally rotatable around the axis of rotation (x), to a tightened configuration, at which the relative orientation of the attachments (2, 3; 3'; 3") is blocked; causing a pressure of the mobile jaw (5) on the first connection bar (101) in the direction of the internal arm (22), performing therefore an action of restraining of the first connection bar (101) in the lateral housing (20). act5 o" L oo</p> |
