Abstract
Capsule endoscopes now used in gastrointestinal tract are carried through the body in one way by the peristaltic movement of the stomach and the intestines. In other words, one cannot control the motion of a capsule endoscope in a patient’s body. Yet it is impossible to stop the capsule endoscope to examine an exact part with suspicious symptom. Besides, due to smaller peristaltic movement and the size of the stomach, it is still difficult to use capsule endoscope to make the diagnosis.
To improve the capsule endoscope system and enhance the efficiency of the diagnosis, we start this research which refers to the idea of Dr. Gi-Shih Lien, vice Superintendent of Wan-Fang Medical Center. With the guidance of Dr. Chih-Wen Liu, Professor of National Taiwan University, we integrate related external magnetic control theory and research on optical devices. By applying the technique of magnetic control, capsule endoscope internal to the body can be controlled to move, whirl, and yaw by the drawing of magnetism outside body. Then the image of gastrointestinal tract can be taken by the optical device of the capsule endoscope and monitored by dedicated driver.
We also emphasize the application of the interface of the capsule endoscope system fabricated during the process of this work. Our goal is to build an easy and low-cost external control system can be used to operate the capsule endoscope internal to the body freely, quickly, and precisely.
Finally, according to the fabrication and simulation of the system for experiment, we analyze the data and outcome to verify our theory and evaluate feasibility of the whole system for further discussion of what should be taken into account while realizing a better capsule endoscope system in the future.
