“…Crossing two grasping forceps and prior clipping can accomplish tissue approximation with adequate precision and dexterity, but only in the direction of traction and not counter-traction. The reason for this limitation is that endoscopes and their accessories are made to be extremely flexible, in order to avoid tears and perforations inside the gastrointestinal lumen, and therefore cannot transmit force in both direct and sideways directions [3]. Traction (pulling) could prove an exception to this rule insofar as it can be satisfactorily accomplished, provided the two forceps are securely grasped in crossover direction.…”

“…Experiments conducted with the Olympus GIF-2T100 reveal a pushing force of approximately 1.3N before the endoscope changes its bent shape [53]. From another study using a different endoscope GIF-140, the maximum pulling force from the endoscope is approximately 2.76N before it changes its original bent shape [54].…”
