The invention discloses an orthopedic fixator for the outside of the clavicle. The orthopedic fixator mainly comprises shoulder fixing frames, clavicle fixing screws, a buffer cotton pad, a shoulder shape clamping pad, a fixing band clamping groove, a fixing band and a fixing band bonding strip. The shoulder fixing frames are formed by forging special metal materials, the length of the portions, penetrating through the shoulder fixing frames, of the screws is controlled through knobs, therefore, pressing sheets at the bottoms of the screws are pushed, pressure is applied to the shoulder shape clamping pad, then pressure is indirectly applied to the buffer cotton pads, and the effect of fixing the outside of the clavicle is achieved. Titanium alloy is adopted as the shoulder fixing frames, the specific strength is high, the mechanical property is close to that of the human skeleton, and fatigue resistance, corrosion resistance and biocompatibility are excellent. The polyethylene natural magnet therapy buffer cotton pad is made from multiple magnetic ingredients, blood circulation of the clavicle region can be effectively improved, wound growth is promoted, meanwhile, the bone mineral density is improved, sclerotin is optimized, and growth restoration of the clavicle is accelerated. The fixator is simple in structure, reasonable in design and high in practicality.
