Abstract
This paper describes the development of an endoscopic device veering-out the latex tube with jamming of granular materials. Colorectal cancers can be cured completely if they are discovered early with a large intestine endoscope. While the endoscope can be used to screen and heal this cancer, its operation is difficult. Peculiarly difficult operation is to pull up a sigmoid colon. In this study, to solve the difficulty associated with the use of this endoscope, we consider that an endoscope is passed through a sigmoid colon by simply pressing without the need to pull up the sigmoid colon. Therefore we propose an endoscopic device veering-out the latex tube with jamming of granular materials. First this device can automatically set flexible tube in a sigmoid colon by veering-out the tube and metamorphose hardness of the tube by jamming of granular materials. Secondly endoscope is easy passed through in the hard tube by only pushing. In this paper, we executed stiffness experiment to select jamming granular. Moreover we perform driving test of veering-out the latex tube to establish whether the method can automatically set flexible tube in a sigmoid colon.
