<p>An endoscope including a control section and a shaft extending from the control section. The shaft includes a frame including a one-piece tube. The tube includes at least one slot into the tube to form spaced sections on opposite sides of the slot. A first one of the sections includes at least one projection which extends into at least one pocket of a second one of the sections such that the projection and pocket form an over-travel limiter to limit relative motion of the first and second sections relative to each other in at least one direction. The one-piece tube has a plurality of the projection and a plurality of the pocket. The plurality of projections are arranged in a general spiral pattern around a longitudinal axis of the tube.</p> |
