Disclosed is a 3D repositor for a clavicle fracture, comprising two support rods (1) and a first reset device. A support rod (1) has a straight rod portion and a curved rod portion. The two support rods (1) are rotatably connected together at one end portion of the curved portion. Corresponding positions of the two support rods (1) have vertically downward positioning holes (3), respectively. Each set of first reset devices comprises two upright columns (5) and a cross rod (6), wherein the two upright columns (5) are vertically mounted on the straight rod portions of the two support rods (1), respectively； the two end portions of the cross rod (6) are movably mounted on the upper end portions of the two upright columns (5), respectively； and the cross rod (6) is provided with a plurality of reset holes (8), with the diameter of the reset holes (8) matching that of a Kirschner wire (9). The 3D repositor for a clavicle fracture has an ingenious design, a simple structure and is very convenient to use, wherein the distance between two segments of fractured clavicle can be controlled via a second reset device, and repositioning of the fractured clavicle can be performed in a plurality of directions, including up, down, left and right, via the Kirschner wire (9) matching the first reset device, enabling 3D spatial stable repositioning to be performed effectively on a clavicle fracture.La présente invention se rapporte à un dispositif de repositionnement 3D pour fracture de la clavicule, comprenant deux tiges de support (1) et un premier dispositif de réinitialisation. Une tige de support (1) a une partie de tige droite et une partie de tige incurvée. Les deux tiges de support (1) sont reliées rotativement l'une à l'autre au niveau d'une partie d'extrémité de la partie incurvée. Des positions correspondantes des deux tiges de support (1) ont des trous de positionnement verticalement vers le bas (3), respectivement. Chaque ensemble de premiers dispositifs de réinitialisati
