| Sumario: | Jonathan D Litten1, JungHun Choi2, David Drozek31Department of Mechanical Engineering; 2Department of Mechanical Engineering and Biomedical Engineering Program; 3College of Osteopathic Medicine, Department of Specialty Medicine, Ohio University, Athens, OH, USAAbstract: A colonoscopy add-on device has been developed to reduce intubation time without modification of the current colonoscope and peripheral devices. One of the main purposes of the system is to minimize trauma caused by the distal tip of the colonoscope. The detachable sensory fixture at the end of the distal tip measures the distance between the distal tip and the colon wall in three directions, and the actuation system attached at the base of the colonoscope controls the distal tip by rotating two dial knobs. The device controls the distal tip to minimize contact between the distal tip and the colon wall, and the distal tip ideally points out the next possible lumen. A compatibility test of the infrared sensory system was carried out, and the design of the actuation system was accomplished. The system is integrated and controlled by a microprocessor. The device was tested in a silicon colon and porcine intestine. The results showed that a colonoscopist successfully reached the cecum with the aid of the colonoscopy add-on device without significant contact between the colon wall and the distal tip. The colonoscopy aid device was very helpful for the novice colonoscopist.Keywords: colonoscope, infrared sensors, intubation, trauma, colonoscopy training model |
