The existing dynamical systems of wireless capsule endoscopy are studied and analyzed. Based on the shortcomings presented in paper, a novel driving method is proposed. That is driving the wireless capsule endoscopy with three-dimensional orthotropic magnetic field outside the human body, and the resultant magnetic field can be obtained and adjusted through the electric current flowing in three coils orthogonal to each other. This paper focuses on the analysis of complex moving mode of wireless capsule endoscopy, and the result is very important to the design of drive and control circuit. |
