<p>An insertion device and an endoscope which can be inserted and extracted from a small incision and have multiple functions. A device body (11) is provided with grip forceps (21) serving as a treatment means. A first folding back section (12) and a second folding back section (13) are provided at the distal portion of the device body (11) so as to be disposed side by side in a row in the longitudinal direction of the device body (11). The first folding back section (12) and the second folding back section (13) respectively have image obtaining means (22, 23). An operation means (14) can move the first folding back section (12) to a folded back position at which the first folding back section (12) is folded back relative to the second folding back section (13), and the operation means (14) can also move the second folding section (13) to a folded back position at which the second folding back section (13) is folded back relative to the device body (11). Also, the operation means (14) can move the first folding back section (12) and the second folding back section (13) to serially located positions in which the first and second folding back sections are arranged in a row aligned with the device body (11). When the first and second folding back sections are at the folded back positions, the grip forces (21) and the image obtaining means (22, 23) are adapted to function in the distal direction of the device body (11).</p> |
