ABSTRACT:
A bending control device of an endoscope for bending a bendable portion, formed at the distal end of the insert part of the endoscope, by manual operation of a control part connected to the proximal end of the insert part is provided. The bending control device has an up and down bending control knob rotatably and detachably provided on the control part to control bending of the bendable portion in upward and downward directions. A right and left bending control knob is rotatably and detachably provided on the control part, in coaxially superposed relation to the up and down bending control knob, to control bending of the bendable portion in the rightward and leftward directions. An attaching and removing device is also provided for manually attaching and removing the two bending control knobs to and from the control part. Thus, the bending control knobs can be removed from the control part as desired for washing and disinfection or replacement with new bending control knobs.
