Colonoscope

Description

A 3D model of a colonoscope navigating through the large intestine, showing the flexible scope passing from the rectum through the sigmoid, descending, transverse, and ascending colon toward the cecum. The instrument tip with its camera, light, and working channel is visible. Colonoscopy is the gold standard for colorectal cancer screening and diagnosis. The flexible endoscope allows direct visualization of the colonic mucosa, detection and removal of polyps, and biopsy of suspicious lesions. The instrument navigates the splenic and hepatic flexures through a combination of tip deflection, torque, and scope advancement. Polypectomy during screening colonoscopy reduces colorectal cancer incidence. Colonoscopy anatomy and technique are essential teaching topics in gastroenterology and colorectal surgery.
