胶囊内窥镜因其舒适性高、无交叉感染等优点,广泛用于消化道疾病检查,但因为无磁控或弱磁控,无法在小肠实现自由高效可控检查.为克服这一缺点,文中基于机械臂操纵的胶囊内窥镜磁导航系统被提出.该系统由机械臂、外部磁源、主从控制系统及磁性胶囊内窥镜组成,通过改变机械臂的姿态和位置实时调节磁性胶囊内窥镜的位姿,提高控制的准确性.通过搭建磁驱动试验平台测试胶囊内窥镜肠道中的操控性能试验,验证了方案可行性,表明机械臂操纵胶囊内窥镜磁导航系统能够满足肠道高效镜检要求,为下一步推向临床奠定了基础.
Capsule endoscope's magnetic navigation systemcontrolled by mechanical arm
Capsule endoscopes are widely used for gastrointestinal inspection due to their user-friendliness and no cross-infec-tion.However,because of no or weak magnetic control,it is impossible to achieve free and efficient examination in small intes-tines.In this article,in order to overcome this shortcoming,a magnetic navigation system is specifically designed for the capsule endoscope,which is controlled by the manipulator arm.This system is composed of a mechanical arm,an external magnetic source,a master-slave control system and a magnetic capsule endoscope.The magnetic capsule endoscope's position and posture can be adjusted in real-time by changing the mechanical arm's posture and position,so as to improve the accuracy in control.A magnetic-driven experimental platform is set up to test the the capsule endoscope's control performance in the intestine;the ex-perimental results verify that this scheme is feasible.It is shown that the capsule endoscope's magnetic navigation system con-trolled by the mechanical arm meets the requirements of efficient intestinal endoscopy,which lays a solid foundation for the next step to clinical research and application.
