Intubation by elongation

Intubation by elongation. A. The sigmoidoscope is advanced to the proximal sigmoid. B. Severe tip deflection prevents further advancement resulting in sigmoid elongation. C. Clockwise torquing and shaft withdrawal accordionizes the sigmoid.

Minor Tip Deflection with gentle advancement

A. Minor tip deflection with gentle advancement and mild torsion allows the endoscope to traverse bends while maintaining a gentle curve. B. Sharp angulation of the tip (like a candy cane) hinders advancement and may result in paradoxical motion, where th

Rotating wheels on the headpiece of the endoscope

Rotating wheels on the headpiece of the endoscope control tip deflection. Instruments may be passed through an access port, which is kept capped when not in use (to prevent loss of insufflation and splashing of fluids).
