An endoscope includes an outer shaft (10) with a substantially circular cross section, an inner shaft (11), which is arranged within the outer shaft (10) and whose cross section comprises a rounded section (31) and a straight section (30), which merge into one another at two corners (32), an optical system (12) within the inner shaft (11), a flexible working instrument (13) between the outer shaft (10) and the straight section (30) of the inner shaft (11), a deflecting lever (17), which is pivotally arranged at the distal end of the straight section of the inner shaft (11), at least one actuating rod (19), by means of which the deflecting lever (17) may be pivoted by means of an actuating device arranged at the proximal end of the endoscope and at least one guide device, in which the actuating rod is arranged. The actuating rod (19) is arranged within the inner shaft (11) and the guide device is constituted by one of the corners (32) and the optical system (12). |
