Abstract
An endoscope has a first bending portion, a second bending portion, and a hand-held unit. The first bending portion is the distal portion of an elongated insertion member and has a plurality of joint pieces concatenated so that the joint pieces can rotate freely. The second bending portion is located at the proximal end of the first bending portion, and has a plurality of joint pieces concatenated so that the joint pieces can rotate freely. The hand-held unit is located at the proximal end of the insertion member, and has a control section that is used to bend the first bending portion and second bending portion. In the endoscope, the control section of the hand-held unit has an angling knob that is used to bend the first bending portion, and a second angling lever that is used to bend the second bending portion.
