관형소화기관 진단을 위한 전자기 구동 캡슐내시경의 3차원 나선형 운동

다국어 초록 (Multilingual Abstract)

We propose a new electromagnetic actuation system for capsule endoscope with steering, locomotion and rotational motion. The proposed electromagnetic actuation system consists of 3 pair of Helmholtz oils and 1 pair of Maxwell coils. The precessional motion and ascending motion of the magnetic capsule endoscope were realized using the proposed electromagnet actuation system. In addition, the magnetic capsule endoscope can move in an esophagus by the propulsion and the rotation with centrifugal force. First, we fabricated a capsule endoscope prototype with a desired magnetization direction and verified its scanning function through the helical motion of the capsule endoscope prototype in the mock-up of tubular digestive organs. Second, the capsule endoscope prototype also has a propulsion force to the perpendicular direction of axial vector when it tracks the helical path, and this force makes the capsule endoscope prototype to attach the inner wall of tubular environment. Through various experiments, the precession of the magnetic capsule endoscope using a glass tube was demonstrated and the feasibility of the capsule endoscope actuated by the electromagnetic actuation system was verified.
