Abstract

In previous works, when studying the frictional behaviour of the small intestine, the small intestine was always in a natural state. However, when a capsule endoscope is travelling through the small intestine, since the diameter of the capsule endoscope may larger than the small intestine, the small intestine is then expanded in circumferential direction, which implies that previous works are not sufficient. This work uses flat–flat contact to simulate a capsule travelling through the small intestine, comparing the frictional behaviour of the small intestine in its natural and circumferentially expanding states, analysing the effects of other factors such as load, velocity and lubrication, which provides a realistic basis for the optimisation and control of magnetically controlled endoscopes.

圆周延伸对小肠摩擦力的影响
在以往的研究中,在研究小肠的摩擦行为时,小肠总是处于自然状态。然而,当胶囊内窥镜穿过小肠时,由于胶囊内窥镜的直径可能大于小肠,小肠会随之向圆周方向扩张,这意味着以前的研究是不够的。这项研究利用平-平接触模拟胶囊在小肠中的运动,比较了小肠在自然状态和周向扩张状态下的摩擦行为,分析了负载、速度和润滑等其他因素的影响,为磁控内窥镜的优化和控制提供了现实基础。
