When the snare wire projects from the distal end of the sheath, it forms a loop that expands due to its own elastic restoring force. The snare wire is hooked on the polyp, then the operating wire is pulled, and the snare wire is pulled into the sheath from the distal end of the sheath. After the polyps are bound tightly, the snare wire can be cut by applying a high-frequency current.
