title: [Study of the movements of flexible endoscopes].
abstract: Examinations of the intestinal tract by conventional clinical endoscopic methods have shown that in the course of observations colonoscopes are subjected to a greater load than esophagogastroscopes. The load is greater by a factor of 2.2 in a number of translational motions and by a factor of 4.4 in a number of rotatory motions. Control grips are subjected to 2.5 times as much load as esophagogastroscopic controls, and colonoscopic tube bending is 2.8 times greater than that of esophagogastroscope.
