Bone drilling is an important procedure in medical orthopedic surgery and it is inevitable that heat will be generated during the drilling process and higher temperatures can cause thermal damage to the bone tissue near the drilled hole. Therefore, the capability to obtain the cortical bone drilling temperature distribution area can have great significance for medical bone surgery. Based on the theory of heat transfer, a predictive model for cortical bone drilling temperature distribution was established. The energy distribution coefficient in cortical bone drilling was derived, based on conjugate gradient inversion. A cortical bone drilling experiment platform was built to verify the temperature distribution prediction model. The results show that the model of cortical bone drill temperature distribution could predict accurately the drilling temperature distribution, both for different depths and for different radial distances. Additionally, the effects of different drilling conditions (spindle speed, feed rate, drill diameter) on the temperature of drilling cortical bone were considered.
骨钻削是医学骨科手术中的一个重要程序，在钻削过程中不可避免地会产生热量，较高的温度会对钻孔附近的骨组织造成热损伤。因此，能够获得皮质骨钻削温度分布区域对于医学骨手术具有重要意义。基于传热理论，建立了皮质骨钻削温度分布的预测模型。基于共轭梯度反演，推导出皮质骨钻削的能量分布系数。建立了皮质骨钻削实验平台来验证温度分布预测模型。结果表明，皮质骨钻削温度分布模型可以准确预测不同深度和不同径向距离的钻削温度分布。此外，还考虑了不同钻削条件（主轴转速、进给速度、钻头直径）对钻削皮质骨温度的影响。
