摘　　要：总结了国内外学者研究胶囊内窥镜主动式运动机构的最新进展,分析了不同机构的运动和控制原理,比较了它们的优缺点。由于人体肠道的复杂性,以及胶囊内窥镜对运动机构的尺寸和功耗的限制,目前还没有采用主动式运动机构的内窥镜胶囊用于临床。永磁体外部旋转磁场激励运动机构可以对已经商业化的内窥镜胶囊进行改进,但旋转磁场较为复杂。采用形态记忆合金激励的主动式运动机构将是今后的发展方向和研究重点。This review summarized the progress of researches on the active locomotion system for capsule endoscope,analyzed the moving and controlling principles in different locomotion systems,and compared their merits and shortcomings.Owing to the complexity of human intestines and the limits to the size and consumption of locomotion system from the capsule endoscope,there is not yet one kind of active locomotion system currently used in clinical practice.The locomotive system driven by an outer rotational magnetic field could improve the commercial endoscope capsule,while its magnetic field controlling moving is complex.Active locomotion system driven by shape memory alloys will be the orientated development and the point of research in the future.
