Figure 6. Schema for SB Knife Jr and the conventional tip-type knife. SB Knife Jr has a forceps length of 3.5 mm, an opening width of 4.5 mm, and an opening angle of 105°. Assuming a fan-shaped dissection surface, a single grasp and dissection action enables the clinician to cut approximately 11.2 mm2 of tissue. In contrast, assuming a rectangular dissection surface, the tip-type knife with a 1.5 mm forceps length requires a horizontal movement of approximately 7.5 mm to cut the same length of tissue. In the difficult-to-operate large intestine, these movements require advanced endoscopic techniques.
