As the scope follows the contours of the large intestine, the student must negotiate the sigmoid colon, splenic flexure, and hepatic flexure before viewing the internal structure of the ascending colon and cecum. As the flexible sigmoidoscope is withdrawn, the student can identify benign sessile, pedunculated and hyperplastic polyps, as well as cancerous lesions. There are a total of 12 pathological conditions to diagnose. All manipulative and photographic techniques can also be practiced. Originally produced exclusively for ACMI, this simulator has been used for physician training nationwide. Life/form® Sigmoidoscopic Examination Simulator is available on a solid oak stand complete with lubricant, instruction guide, and hard carrying case. Three-year warranty. Size: 26" x 19" x 7".
