PROBLEM TO BE SOLVED: To provide a skeletal fixation device that enables stimulation of skeletal growth fixation by tremor and good fixation.SOLUTION: A skeletal fixation device of the present invention comprises a main body and a movable frame. A receiving hole penetrating through a top surface and a bottom surface is provided in the main body, and the first comb teeth are provided in the top surface and the bottom surface. The movable frame is positioned in the receiving hole, and is provided with a through-hole penetrating a first face and a second face in the vertical direction. A first end of the movable frame is connected with a main body front end, a second end is opposed to a main body rear end while being in the air, and the second comb teeth are provided in the first face and the second face. The movable frame is separated into the upper part and the lower part by a dividing groove, and is provided with the elastic extending force using the first end as a fulcrum in the upper part and the lower part. When a main body front end is embedded between two skeletons, the first comb teeth provide the first action force, the second comb teeth provide the second action force, and the differential between the second action force of the second comb teeth and the first action force of the first comb teeth to the two skeletons is supplemented by being controlled so that the second action force may be different from the first action force.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】本発明は、微動による骨格増殖固定の刺激と、良好な固定が可能な、骨格固定装置を提供する。【解決手段】本発明は、本体と、可動フレームとからなる。本体には頂面・底面を貫通する収容孔が設けられ、頂面・底面には第一櫛歯が設けられる。可動フレームは収容孔中に位置し、且つ第一面・第二面を縱向きに貫通した通孔が設けられる。可動フレームの第一端は本体前端と結合され、第二端は宙に浮いた状態で本体後端と相対し、第一面・第二面には第二櫛歯が設けられる。可動フレームは分断溝によって上部・下部に区切られ、且つ上部・下部には第一端を支点とする弾性的拡張力が備わる。本体前端が二つの骨格間に埋め込まれた時、第一櫛歯が第一作用力を提供し、第二櫛歯が第二作用力を提供し、且つ第二作用力が第一作用力と異なるように制御することで、二つの骨格に対する第二櫛歯の第二作用力と第一櫛歯の第一作用力との差動が補われる。【選択図】図2
