摘　　要：目的:利用外磁场驱动无线胶囊式内窥镜,可以使患者吞服的无线肠胃内窥镜在医生的控制下做多自由度的移动,使内窥镜的摄像头直接在可疑区域做有针对性的检查,大大增加了检查的成功率。方法:依靠3组线圈产生的磁场可以对处在任意位置、任意方向的附带有磁性材料的无线胶囊式内窥镜产生作用力。通过改变线圈内电流的大小和方向,操控胶囊内窥镜在人体内的位置以及指向。结果:设计出简单的操作装置,实现线圈的操作,进而实现对无线胶囊式内窥镜的控制。结论:外磁场驱动的无线胶囊式内窥镜减小了内窥镜的整体体积和质量,减轻了肠胃检查时的痛苦,缩短了医生的检查时间,使医生控制其移动更为容易和灵活。Objective To drive the wireless capsule endoscopy that could be swallowed by the patients by external magnetic field so that it could move freely under the control of doctors,which made the vidicon of endoscopy work purposefully in the dubitable area,and improved the efficiency of check greatly.Methods The magnetic field from three sets of coils could create effect to wireless capsule endoscopy with magnetic material.By controlling coil＇s circuit and its direction,the wireless endoscopy in body could move to any places and point to any direction.Results The design of operating device controlling coils was given in this paper,and came to realize the aim controlling the moving of wireless endoscopy.Conclusion The wireless capsule endoscopy driven by external magnetic field makes the size and weight of endoscopy less,which alleviates pain in gastroscopy and improves the working efficiency of doctors.
