Description
Specially serrated snare for better endoscopic tissue acquisition.
Use of the Traction Polypectomy Snare
Instrument for flexible endoscopy for grasping and removing tissue in the gastrointestinal tract
The Traction Polypectomy Snare
Ovesco’s Traction Polypectomy Snare is a newly designed, serrated snare for endoscopic tissue acquisition procedures such as polypectomy, endoscopic mucosa resection (EMR) or similar techniques. It is a monopolar high-frequency instrument.
Enhanced effectiveness of snare resection:
- 30% more tissue capture per resection*
- solid grip even on flat adenomas
- re-positioning of snare if needed
- reduced number of specimens
- histo-pathological assessment facilitated

Application of the Traction Polypectomy Snare
EMR+
Injection into the submucosa
Positioning of snare and OTSC® Anchor or FTRD® grasper
Elevation of the lesion and snare closure
Push-back* of the OTSC® Anchor or FTRD® Grasper while snare stays closed and subsequent resection
*Note: Anchor needles must not be captured with the snare during the push-back move. If in doubt, the anchor needles can be closed to avoid a short circuit.

Excerpt from the summary:
„In this experimental study a new snare with special teeth (Traction Polypectomy Snare) attached to the distal part of the wire loop was evaluated and compared to a conventional snare. 70 artificial sessile tumors were created in a standardized manner in a porcine ex vivo colon. 35 flat polyps were resected with the new serrated snare, whilst the other 35 polyps were removed using an identical snare without teeth. The weight measurement of the resected polyps showed that using the new serrated snare 31% more tissue could be removed with a single snare resection in comparison with the conventional snare without teeth (mean 454 mg vs. 347 mg, ±202 mg vs. ±165 mg; p = 0.017). The teeth obviously increased the effectiveness of snare resection by avoiding the accidental loss of entrapped tissue from the loop. The new snare will facilitate the removal of flat polyps and reduce the number of specimens during piecemeal resection to a minimum, allowing a better histopathological assessment.”
