⭕ The PCF-160AL/I video colonoscope utilizes the new innoflex technology to let its user adjust the flexibility of the insertion tube for optimal insertion. New with the EVIS EXERA 160 Series of video colonoscopes, this variable stiffness insertion tube provides greater maneuverability for its user and less discomfort for the patient. At the same time, it reduces the chance of looping and makes insertion beyond the splenic flexure easier.
