摘要
通过分析既有的消化道胶囊内窥镜驱动方式,针对其控制复杂、可靠性低、有可能损伤消化道、能量需求过大以及驱动受消化道尺寸限制等缺点提出采用外加磁场靠磁力驱动的方案,以期望实现不消耗胶囊内窥镜内部能量、不受消化道尺寸限制的无损害驱动方式。结合胶囊内置小磁体的受力分析,外加磁场的特性,用ANSYS软件仿真常规线圈模型和超导线圈模型,发现常规线圈无法满足驱动要求,而超导线圈有可能实现磁引导驱动。
Existent ways for driving capsule endoscopes in intestine were analyzed. With whose fault,such as controlling complexity, lower reliability, possibility of damage to intestine, considerable requirement for power, limit from intestine size,a new driving way using magnetic field was held out. According to the mechanics analysis on the tiny magnet in the capsule endoscope and the characteristic of magnetic field,a copper coil model as well as a superconductor model was emulated with ANSYS software. The fact came out that the copper coil would be never fit for the magnetic guidance driving, but the superconductor coil may have a better prospect.
