Feasibility Trial of Magnetic-assisted Colonoscope Platform

1. Preparation before examination: All subjects must take bowel cleansing drugs as instructed before magnetically controlled colonoscopy After starting to drink laxatives, subjects should continue their daily activities . 2. Magnetically Controlled Colonoscopy procedure: No anesthesia will be used during the magnetically controlled colonoscopy in this experiment. The subjects lie down on the magnetic control colonoscopy platform. After the magnetically controlled colonoscopy enters the rectum from the subject's anus, the external magnetron is used to assist and guide the pre-colonoscopy after the magnetically controlled colonoscopy enters the rectum from the subject's anus, and the external magnetron is used to assist and guide the colonoscopy go ahead. During the inspection process, the physician monitors the operation of the magnetically controlled colonoscope throughout the process, and the physician can adjust the movement of the colonoscope when necessary. Whole colorectal examination is defined as the colonoscope must be inserted into the ileocecal region, and the cecum must be photographed. 3. Pain assessment during examination: During the colonoscopy, the researchers will conduct a questionnaire to the patients to assess the pain.. The evaluation method is based on the Verbal Scale to evaluate the maximum discomfort, from 0 to 10 points; ; Among them, 0 points are painless, 10 points are the most severe. If the patient's pain assessment score is greater than 5 and the patient cannot tolerate colonoscopy, the examination will be terminated. If there are difficulties during the examination, and the magnetic-controlled colonoscopy cannot complete the examination within 1 hours, the examination shall be terminated. 4. After the colonoscopy is completed, the researcher conducts an overall pain assessment to the subjects by means of a questionnaire. On the day after the colonoscopy, the researcher asked the subjects whether they would like to accept the next colonoscopy follow-up examination by means of a questionnaire. 5. After the magnetic-controlled colonoscopy, the images and time recorded by the colonoscopy will be interpreted by computer-captured images, and the completion rate of the magnetic-controlled colonoscopy will be analyzed.
