摘要： A mandibular fixation device overcomes the low operability of the conventional mandibular fixation device. The mandibular fixation device includes a sleeve, a first screw rod, a second screw rod and two positioning members. The sleeve includes two ends respectively provided with first and second screw holes. The first and second screw holes have opposite spiral directions. The first screw rod has a first threaded portion and a first assembly portion. The first threaded portion is threadedly engaged with the first screw hole, and the first assembly portion is located outside of the sleeve. The second screw rod has a second threaded portion and a second assembly portion. The second threaded portion is threadedly engaged with the second screw hole, and the second assembly portion is located outside of the sleeve. The two positioning members are coupled with the first and second assembly portions, respectively.

摘要： An orthodontic remodeling device includes a sleeve having first and second screw holes in two ends thereof. The first and second screw holes have opposite thread directions. A first screw rod includes a first threaded portion threadedly engaged with the first screw hole and a first assembling portion exposed outside of the sleeve. A second screw hole includes a second threaded portion threadedly engaged with the second screw hole and a second assembling portion exposed outside of the sleeve. Two tooth pushing members are respectively engaged with the first and second assembling portions. Each tooth pushing member includes at least one tooth coupling ring mounted on at least one tooth of a patient for pushing the at least one tooth outward. The sleeve is rotatable to move the first and second screw rods toward or away from each other to change a relative position between the two tooth pushing members.

摘要： A femur supporting device includes a femoral stem having a plurality of inclined passages. The femoral stem includes an inner side and an outer side. Each inclined passage includes an outlet in the inner side and an inlet in the outer side. Each inclined passage inclines upward from the inlet to the outlet. A plurality of supporting rods extends through the inclined passages. A first engaging end of each supporting rod extends out of the outlet of one of the inclined passages. A second engaging end of each supporting rod extends out of the inlet of one of the inclined passages. The first engaging end of each supporting rod is engaged with one of a plurality of first engaging portions in a trochanter head. The second engaging end of each supporting rod is engaged with one of a plurality of second engaging portions of a fixing unit.
