The present invention relates to an external fixator comprises at least four half rings (2) which have ledged areas on each end that provide connections to form full rings, each half ring includes rod holes and channel slots； rod holes are at certain intervals parallel to the axis of the ring, and channel slots are between the rod holes and the outer edge of the ring, narrower than the rod holes； at least four connectors (3) which fix the half rings to each other through the connection holes； at least three threaded rods (4), which have the same diameter with those of the rod holes and fit into the rod holes, and which are in the form of bars that are trimmed longitudinally from two opposite sides of the diameter so as to be equal to the width of the channel slot； nuts (5) which fix the rods (4) to the half rings (2)； at least one Kirschner wire (6) to fix the bones and soft tissues； at least two wire fixation bolts (7) which are passed through the rod holes to fix the Kirschner wire (6) at both ends to the half rings (2)； an apparatus (8) to bend the ends of the Kirschner wire (6), whose one end holds the wire and the other end has a handle to easily bend.La présente invention concerne un dispositif de fixation externe qui comprend au moins quatre demi-anneaux (2) qui présentent des zones à rebord sur chaque extrémité qui fournissent des raccords pour former des anneaux complets, chaque demi-anneau comprend des trous de tige et des fentes de canal ； les trous de tige se situent à certains intervalles parallèles à l'axe de l'anneau et les fentes de canal se situent entre les trous de tige et le bord externe de l'anneau et sont plus étroites que les trous de tige ； au moins quatre raccords (3) qui fixent les demi-anneaux l'un à l'autre via les trous de raccordement ； au moins trois tiges filetées (4), qui ont le même diamètre que ceux des trous de tige et qui s'ajustent dans les trous de tige et qui se présentent sous la forme de barres qui sont coupées longitudinale
