Preparation for thread-traction using a sheath of polypectomy snare (part 1). One end of a thread is tied to the claw of a clip (a), and the clip with the thread is reinstalled into the clip case (b). After the rotatable clip-fixing device is inserted into the channel of the endoscope, the clip with the thread is attached to a rotatable clip-fixing device (c). The other end of the thread is passed through the loop of a polypectomy snare (d).
