Abstract
An endoscope has a handle and a bendable tube extending distally away from the handle. The tube has a selectively deflectable distal segment. An activating wire is connected to the distal segment and to the handle, and the handle has a knob which can be turned to impart force to the wire and thereby cause the distal segment of the tube to deflect. The wire is held by a hypotube column support which is attached to the handle and to the deflectable distal segment, such that when the knob is turned, the column support transfers the force of the wire to the handle to prevent buckling of the bendable tube when the distal segment deflects.
