Advances in endoscopic therapy using grasping-type scissors forceps (with video)

Figure 1 Mechanical features of the clutch cutter. A: Two blade lengths (5 mm and 3.5 mm) are available. The blade is saw-toothed over the entire length of the scissors; B: Rotatable. The blade part can rotate 360°; C: The cutting edge is serrated, and all surfaces other than the cutting edge are insulated; D: Sectional view of the cutting edge. The cutting edge is tapered to a width of 0.4 mm, which is the same width as the polypectomy snare, so that the tissue can be pressed and cut.
