Cold Snare

A Polypectomy Snare is a sterile, single-use Class II medical device (FDA-cleared, CE-marked) used during endoscopy (colonoscopy, gastroscopy, enteroscopy) for resecting polyps and mucosal lesions from the gastrointestinal tract. The device consists of a flexible stainless steel braided wire loop (10-40 mm diameter) that opens and closes via an ergonomic handle, delivered through an insulated PTFE or PEEK sheath compatible with standard endoscopes (working channel 2.0-2.8 mm). Available in various shapes (oval, round, crescent, hexagonal) for different polyp types (pedunculated, sessile, flat). Used with electrosurgical generators for hot snare polypectomy (cautery-assisted) or without for cold snare polypectomy (small polyps). Primary clinical applications include removal of colorectal polyps to prevent colorectal cancer, resection of gastric and esophageal polyps, treatment of bleeding polyps, debulking of large sessile polyps via piecemeal technique, and surveillance in hereditary polyposis syndromes (FAP, Lynch). Critical safety precautions include single-use only, proper electrosurgical technique, ensuring complete polyp capture before current application, submucosal injection for sessile lesions, and post-procedure monitoring for bleeding or perforation. Essential instrument for therapeutic endoscopy and colorectal cancer prevention.
