Fig. 2 — a The 50-mL syringe (31-mm diameter) cannot fit over the forceps insertion hole because the width of the handwheel is only 21 mm around the forceps insertion hole. This interferes with operating the handwheel. b Although the 5-mL (18-mm diameter) syringe is thinner than the width of the wheel, the distance from the wheel to the forceps insertion hole is only 6 mm. Therefore, the tip of the syringe (radius 9 mm) cannot reach the hole. c A 2-mL (10-mm diameter) syringe can be placed over the forceps insertion hole. However, the over-the-scope (OTS) clip forceps insertion hole is narrower and tighter than a standard one, making it difficult to insert a regular syringe with a 4-mm outer diameter tip.
