The utility model relates to a spreader module supporting a bone strength device.The system includes a spreader module.The spreader module comprises an outer sleeve,One body and one grip,A through hole is arranged axially in the outer casing pipe.A joint hole is arranged on the inner circumference of one end.The joint hole is sleeved with a joint part of an implant；The body is hollow.Limit the axial displacement of a tightening block only on the body；A second external thread is arranged around the handle.One end thereof is pivoted with a rotating member.The other end is provided with a torsion part；So as to continuously exert torque on the handle,Pressing the outer sleeve against the implant,The expansion part of the implant is forced to compress and deform by the torsional moment of the thread.So that we can adjust the expansion range,Expandable implants with multi-level arc.一種支撐骨骼強度裝置的撐開器模組，係包含有一撐開器模組，該撐開器模組包括：一外套管、一本體及一握把，該外套管內部軸向貫設一通孔，其一端內周設有一接合孔，該接合孔與一植入物之一接合部相套合；該本體呈中空狀，限制一迫緊塊僅能於該本體上軸向位移；該握把外周設一第二外螺紋，其一端樞接一轉動件，另一端設有一扭轉部；藉此持續對該握把施加扭力，使該外套管擠壓該植入物，透過螺紋之扭轉力矩迫使該植入物之一擴張部擠壓變形，藉以形成一可以調整不同擴張範圍、多層次弧形之可擴張植入物。
