摘要/Abstract

摘要： 金刚石微磨具可以快速精确地去除病灶区骨组织，在骨科手术中受到广泛应用。但生理盐水喷雾式冷却存在微磨具/骨界面铺展浸润性低、磨削温度高的技术难题，易引起生物骨组织热损伤。借鉴沙漠甲虫捕水及定向输运原理，构建仿生沙漠甲虫微磨具，有望解决骨微磨削热损伤的技术瓶颈。基于此，首先研究了仿生沙漠甲虫亲/疏水微磨具表面液滴动力学机制，揭示了表面能与拉普拉斯压力协同作用下的液滴铺展机理，构建了在润湿性梯度、温度梯度等因素影响下的仿生微磨具/骨界面液滴铺展半径模型。然后，进行了仿生微磨具表面液滴铺展实验，探究了液滴在微磨具表面的铺展形态，验证了微磨具表面液滴铺展半径模型，平均误差为10.34%。最后,开展了骨微磨削实验，探究了仿生微磨具骨磨削实验参数对磨削温度的影响趋势和机理。结果表明，仿生微磨具可以增加液滴铺展面积，降低微磨削温度。旨在为降低生物骨微磨削的磨削温度提供理论指导和技术支持。

Abstract: Diamond micro-grinders can rapidly and precisely remove bone tissue in the lesion area, which has been widely applied in orthopedic surgery. However, the technical problems of low spreading wettability at the micro-grinding tool/bone interface and high grinding temperature exist in normal saline spray cooling, which easily causes thermal damage to biological bone tissue. Learning from the principle of water capture and directional transport of desert beetles, constructing biomimetic desert beetle micro-grinding tools is expected to solve the technical bottleneck of thermal damage in bone micro-grinding. Based on this, the dynamic mechanism of droplets on the surface of biomimetic desert beetle hydrophilic/hydrophobic micro-grinding tools is first studied. The droplet spreading mechanism under the synergistic effect of surface energy and Laplace pressure is revealed, and the droplet spreading radius model at the biomimetic micro-grinding tool/bone interface under the influence of factors such as wettability gradient and temperature gradient is constructed. Then, the droplet spreading experiment on the surface of biomimetic micro-grinding tools is carried out to explore the spreading morphology of droplets on the surface of micro-grinding tools, and the droplet spreading radius model on the surface of micro-grinding tools is verified with an average error of 10.34%. Finally, the bone micro-grinding experiment is carried out to explore the influence trends and mechanisms of the bone grinding experimental parameters of biomimetic micro-grinding tools on the grinding temperature. The results show that the biomimetic micro-grinding tools can increase the droplet spreading area and reduce the micro-grinding temperature. It aims to provide theoretical guidance and technical support for reducing the grinding temperature of biological bone micro-grinding.

Key words: microgrinding, grinding temperature, biological bone, bionic tools, droplet spreading
