The utility model discloses a bone orthosis, which belongs to the technical field of
rehabilitation medicine, and comprises mounting blocks and an
operating table, one side of each mounting block is fixedly connected with a fixing mechanism, the other side of each mounting block is fixedly connected with a fixing belt, the two mounting blocks are symmetrical about the
operating table, and the fixing belts are fixedly connected with the fixing mechanisms. Two gear racks in sliding connection are inserted into the operation table, one ends of the gear racks are fixedly connected with the mounting block, limiting teeth are arranged at the other ends of the gear racks, a gear is arranged in the operation table, and the gear is meshed with the two gear racks. According to the bone orthosis, the mounting blocks, the gear rack, the
rotating disc and the gear are arranged, the
rotating disc is rotated to drive the gear to rotate, the gear rack stretches out and draws back through the meshing effect of the gear and the gear rack, and therefore the two mounting blocks fixedly connected with the gear rack are driven to move away from each other or move close to each other, and the orthosis can be applied to different bones; and the orthosis can be repeatedly used, so that the
elimination rate of the orthosis is reduced.
