摘要：
A bone fixing device includes a fixing rod, at least one first bone nail and at least one second bone nail. The fixing rod includes a shaft, a first fixing component and a second fixing component, wherein the first fixing component and the second fixing component are connected to two opposite ends of the shaft respectively. The first bone nail has a first fixed end and a first fastened end opposite to each other, wherein the first fixed end is fixed to the first fixing component, and the first fastened end is fastened to a first bone. The second bone nail has a second fixed end and a second fastened end opposite to each other, wherein the second fixed end is fixed to the second fixing component, and the second fastened end is fastened to a second bone. The material of the shaft includes shape memory alloy and the shaft is deformed due to temperature variation, so as to drive the second fastened end to move relatively to the first fastened end.一種骨骼固定裝置,包括一固定桿、至少一第一骨釘及至少一第二骨釘。固定桿包括一桿件、一第一固定件及一第二固定件,其中第一固定件及第二固定件分別連接於桿件的相對兩端。第一骨釘具有相對的一第一固定端及一第一鎖附端,其中第一固定端固定於第一固定件,且該第一鎖附端鎖附於一第一骨骼。第二骨釘具有相對的一第二固定端及一第二鎖附端,其中第二固定端固定於第二固定件,且第二鎖附端鎖附於一第二骨骼。桿件的材質包括形狀記憶合金且桿件藉由一溫度變化產生一變形,而帶動第二鎖附端相對於第一鎖附端產生一位移。50‧‧‧第一骨骼60‧‧‧第二骨骼100‧‧‧骨骼固定裝置110‧‧‧固定桿112‧‧‧桿件114‧‧‧第一固定件114a‧‧‧第一連接端114b‧‧‧第一自由端116‧‧‧第二固定件116a‧‧‧第二連接端116b‧‧‧第二自由端120‧‧‧第一骨釘120a‧‧‧第一固定端120b‧‧‧第一鎖附端130‧‧‧第二骨釘130a‧‧‧第二固定端130b‧‧‧第二鎖附端D‧‧‧方向F‧‧‧壓迫力
