An insertion unit 2 of an endoscope 1 includes a distal section 8, a bending section 9 that can bend freely, and a soft section 10 having flexibility in that order from the distal end thereof. The soft section 10 has as the distal part thereof a small-diameter portion 10a, a large-diameter portion 10b, and a tapered portion 10c linking the small-diameter portion 10a and large-diameter portion 10b. At least part of the tapered portion 10c is located ahead of a point that is 70 cm away from the distal endoscope end. When the insertion unit 2 is inserted into the large intestine, if the distal section 8 is moved the shortest distance to the cecum, the distance from the anus to the distal section 8 is known to generally range from approximately 60 cm to approximately 70 cm. Therefore, at least part of the tapered portion 10c is located at a position that is 70 cm or less from the distal endoscope end, whereby excellent insertion efficiency is ensured.
L'invention concerne un endoscope (1) comprenant une partie à insertion (2) constituée d'une partie d'extrémité (8), d'une partie courbe flexible (9) et d'une partie souple (10) béquillable, disposées dans cet ordre à partir de l'extrémité. L'extrémité de la partie souple (10) comprend une partie de faible diamètre (10a), une partie de grand diamètre (10b), ainsi qu'une partie tronconique (10c) reliant la partie de faible diamètre (10a) et la partie de grand diamètre (10b). Lorsque la partie à insertion (2) est insérée dans le gros intestin et la partie d'extrémité (8) dans un caecum sur une plus petite distance, la distance entre l'anus et la face d'extrémité de la partie d'extrémité (8) est généralement comprise entre 60 et 70 cm. De ce fait, pour que cet endoscope soit facile à insérer, au moins une partie de la partie tronconique (10c) est disposée à 70 cm de l'extrémité de l'endoscope.
