With the increasing emphasis on health and the continuous improvement of medical standards, more and more micro/nano devices are being used in the medical field. However, the existing micro/nano devices cannot effectively solve various problems encountered in medical processes and achieve specific therapeutic effects. Based on this, this article designs a new type of nanoscale drilling rig. The nanoscale drilling rig is composed of double-layer nested carbon nanotubes with multiple electrodes, and is powered by an external power source, making it easy to perform long-term surgery in the human body. Through coding strategies, we can adjust the surface charge density and distribution of the nanoscale drilling rig, thereby controlling its periodical rotation and achieving precise medical treatment. In addition, in order to control the length of the nanoscale drill bit, meet the treatment needs of different parts of the human body, and reduce damage to the human body, we have designed a structure of ion electric double layers so that the drill bit can be fixed in different positions, reducing the risk of treatment to a certain extent. This drilling rig enriches the functions of micro/nano devices, which is beneficial for the development of the medical industry.

基于嵌套碳纳米管的纳米钻机驱动机构

随着人们对健康的日益重视和医疗水平的不断提高，越来越多的微纳器件被应用于医疗领域。然而，现有的微纳米器件并不能有效解决医疗过程中遇到的各种问题并达到特定的治疗效果。基于此，本文设计了一种新型纳米级钻机。该纳米级钻机由双层嵌套碳纳米管和多个电极组成，并由外部电源供电，方便在人体内进行长期手术。通过编码策略，我们可以调节纳米级钻机的表面电荷密度和分布，从而控制其周期性旋转，实现精准医疗。另外，为了控制纳米级钻头的长度，满足人体不同部位的治疗需要，减少对人体的伤害，我们设计了离子双电层结构，使钻头可以固定在不同的位置，一定程度上降低了治疗的风险。该钻机丰富了微纳器件的功能，有利于医疗行业的发展。
