近年来，在各种外科手术中，对骨的微钻孔的需求越来越大。该手术的主要挑战之一是控制钻孔过程并避免周围组织损伤。对切割状态的监控有望成为提高机器人手术安全性和应用自动化解决方案的一种有前途的方式。然而，仍然没有有效的方法来解决这个问题。本文报道了利用声发射传感测量监测骨切割过程的可能性，并支持对这种独特材料的切割现象的理解。为此，研究了骨微钻声发射信号的主要频段。对骨微钻削过程中的声发射信号与切屑形态之间的关系进行了分析。提出了一种基于小波变换和分形分析相结合的微钻削过程中钻削位置和切削故障的检测方法。牛肋骨微钻孔的实验结果表明，所提出的AE传感措施具有很大的潜力，可用于监测骨微钻孔过程的有效和易于实施的解决方案。(C)2015 Elsevier B.V.版权所有。
Micro-drilling of bone is increasing demanded in many kinds of surgery operations recently. One of the mainly challenges in this procedure is to control the drilling process and avoid the surrounding tissue damage. Monitoring the cutting condition is expected to be a promising way for safety enhancement and application of automated solution for robot surgery. However, there is still no efficient method to meet this issue. The present paper reports on the possibility of using AE sensory measure for monitoring bone cutting process and support the understanding of the cutting phenomena on this unique material. For this purpose, the main frequency band of AE signal in bone micro-drilling was studied. Chip formation analysis was carried out to capture the relationship between AE signal and the chip morphology in bone micro-drilling process. A wavelet based approach was proposed to detect the penetration position of the micro drill and cutting malfunctions in micro-drilling process combined with the fractal analysis. The experimental results with micro-drilling of bovine rib bone showed good evidence that the proposed AE sensory measures have a great potential to be used in efficient and easily implementable solutions for monitoring the bone micro-drilling process.
