摘要
骨钻孔是外科手术中的常见操作之一,为了解决钻骨过程中钻削温度过高导致骨细胞坏死和钻削力过大出现骨裂纹等问题,文中提出了一种利用正弦曲线端面凸轮实现轴向低频振动的手持式骨钻并搭建了测试平台,试验分析了低频辅助振动钻骨过程中进给速度、主轴转速及低频辅助振动振幅对钻削力和钻削温度的影响。试验结果表明:与普通的骨钻削相比,引入轴向低频辅助振动可以有效减小骨钻削过程中的钻削力和降低钻削温度。钻削力最大可减小约30%,温升最大可降低约21%,在实际手术过程中可以通过控制和优化匹配钻削参数达到该目的。此外,低频辅助振动钻削时孔的表面质量和形貌也优于常规钻削的情况。
Bone drilling is one of the common operations in surgery.In this article,in order to solve such problems as bone necrosis caused by excessive drilling temperature and bone cracks caused by excessive drilling force during the process of bone drilling,efforts are made to propose a handheld bone drill that uses a sinusoidal curve end-face cam to achieve axial low-frequency assisted vibration;then,a test platform is set up.The analysis is conducted on the effects of the feed speed,the spindle speed and the amplitude of low-frequency assisted vibration on the drilling force and the drilling temperature through a series of experiment.The experimental results show that compared with ordinary bone drilling,axial low-frequency assisted vibration is helpful to effectively reduce the drilling force and the drilling temperature during the process of bone drilling.The maximum drilling force reduces by about 30%,and the maximum temperature rise reduces by about 21%.In the actual surgical process,the drilling parameters can be controlled and optimized.In addition,the surface quality and morphology of the holes in low-frequency assisted vibration drilling are better than those in conventional drilling.
