ABSTRACT:
An endoscope having control mechanism for permitting fine adjustment of the bending operation of a flexible tip. The flexible tip of an endoscope is controlled in its bending direction by rotating a knob at the opposite end of the endoscope. The knob is engageable by a braking clutch mechanism for stopping the rotation thereof and thereby fixing the position of the endoscope tip. A separate release mechanism is provided for temporarily disengaging the knob from the braking force of the clutch mechanism without requiring the release of the clutching mechanism to its disengaged state. The temporary release mechanism is operated by means of a button located on the knob thereby permitting easy operation while the physician or other operator is performing a viewing operation or the like.
