| 摘 要： | 提出一种结构简单的医用肠道机器人的驱动机构。利用弹性流体动压润滑理论,详细分析计算了肠道机器人在不同弹性模量、不同半径和不同粘液粘度的肠道内的轴向运行速度和形成的粘液膜厚度。结果表明,此种肠道机器人能以较快速度在肠道内悬浮运行。上述分析结果已被肠道试验研究所证实。

| Abstract: | A medical micro-robot moving in human intestine is proposed. The locomotion speed of the micro-robot and hydro-dynamic mucus film thickness formed when the medical mi-cro-robot moving in intestine with various diameters, various viscosity mucus and various modulus of elasticity are calculated according to the elastohydrodynamic lubrication theory. The results indicate that the medical micro-robot can be suspended to move quickly into intestine. The above results are proved by the experiments. |
