Responsive Technology Insertion

RIT - Responsive Insertion Technology

RIT is standard on EVIS EXERA III 190 Series colonoscopes. It is a unique combination of three proprietary Olympus technologies: PB (Passive Bending), HFT (High Force Transmission), and Variable Stiffness.* These technologies work together to improve ease of insertion and operator control, which may help to minimize patient discomfort and enhance procedural efficiency.

* PCF-PH190L/I has PB and HFT only.


PB (Passive Bending)

PB helps EVIS EXERA III 190 Series colonoscopes move through acute bends in the colon. When the scope meets with resistance, the pressure is redistributed so that the insertion tube automatically bends to adjust to the contours of the colon, potentially decreasing patient discomfort and speeding insertion to the cecum.

HFT (High Force Transmission)

HFT provides improved operator control for pushing and twisting maneuvers. Whenever the scope is pushed forward or rotated, the pushing force or rotational torque is transmitted in a 1:1 manner down the length of the insertion tube, meaning the scope reacts more sensitively to physician handling and is easier to maneuver within the colon.

Variable Stiffness

Variable stiffness allows the flexibility of Olympus scopes to be changed incrementally by manipulating a flexibility adjustment ring. This innovative feature allows the scope to be adjusted on a case-by-case basis, to meet the unique anatomical needs of the patient and the handling preferences of the physician.
