电磁场对损伤股骨恢复的作用

Research on the Function of Electromagnetic Field on the Recovery of Injured Thighbone

本文根据骨的压电特性,采用圆形线圈通过方脉冲信号所产生的电磁场这样一个物理模型,从理论上着重分析了脉冲变化的电磁场对骨的刺激作用,提出能够促进损伤股骨恢复的适宜的刺激电流、刺激频率以及刺激电流的方向。

Based on the characteristics of piezoelectric of bone, adopted a physical model of the electromagnetic field that was generated from the rotmd loop crossing impulse signal, in the theoretical level, this study explored the stimulating effects of impulse changes of the electromagnetic field on the bones. The proper stimulating electric current, stimulating frequency and the direction of stimulating electric current that can enhance the recovery of injured thighbone were proposed.
