DEVICE FOR EXTERNAL ORTHOPEDIC FIXATIONS

摘要

Device for external orthopedic fixations, which comprises one or more frames (1; 61; 71) which have a substantially and/or partially annular shape and are suitable for being arranged around a limb to surround it at least partially, wherein one or more rods (2, 36; 46; 96; 106; 110) are fixed to at least one frame (1; 61; 71) by means of at least one locking mechanism (3, 6; 23; 56; 86) provided with at least two jaws (10, 11, 30, 31; 26, 27; 57, 58; 87, 88) which, when they are closed, tighten the locking mechanism (3, 6; 23; 56; 86) to a portion of the frame (1; 61;71) by exerting a prevalently axial force, wherein said jaws (10, 11, 30, 31; 26, 27; 57, 58; 87, 88) are closed by means of a cam mechanism (13, 33) suitable for being actuated by rotating at least one lever (12, 32; 90) pivoted to a first jaw (10, 30) and provided with one or more cam surfaces (13, 33) cooperating with at least one surface of the second jaw (11, 31).
