摘要
设计了一种新型的、基于无线供能的主动式胶囊内窥镜系统,包括胶囊内镜、主动运动、无线供能3个子系统。胶囊内镜子系统可实时获取、传输肠道内部的图像信息;主动运动子系统将微型电机的旋转运动转化为胶囊内窥镜的径向和轴向伸缩,并按照一定的时序配合实现仿尺蠖运动;无线供能子系统接收体外发射线圈产生的电磁场能,将其转换成电能,为整个系统提供能源。后续实验表明:主动式胶囊内窥镜可以运动、定位到肠道病灶点,进行主动式图像诊察,可克服已有胶囊内窥镜不能主动运动,仅靠胃肠蠕动来推动而造成的漏检、误检等缺陷。
A novel active capsule endoscope （ACE）, including capsule endoscope, active movement and wire power transmission, based on wireless power transmission is designed. The subsystem of capsule endoscope can acquire the image of gastrointestinal tract and transmit it out body for inspecting real time. The active movement converts the whirligig of motor into the shrink-spread motion of the axial and radial of the system, and when controlled by a certain time sequence, the ACE can move and locate like a cankerworm. The wireless power transmission receives electromagnetic power transmitted by out body transmitter, rectifies and stabilizes it for the power of the all system. The experiment testified the validity of the design, the ACE can actively move and located in the focus for inspecting, overcome the potential of lost inspecting and mistake inspecting by the passive capsule endoscope （PCE）, for it is moved by the peristalsis of digestive system and thus can＇ t active locate at expectation point.
