Abstract
An endoscope includes an insertion portion, an operation portion, and a fitting mechanism coupling the insertion portion and the operation portion so as to be decouplable. The fitting mechanism includes a plate portion and a convex portion, and a fitted-shape portion and a hole. The convex portion is fitted to the fitted-shape portion. The hole exposes at least one of the plate portion or the convex portion to outside. The fitting mechanism is provided at a position around a center axis, corresponding to a bending wire.

A connection portion of a grasping portion and an insertion portion of an endoscope, comprising:
- a fitting mechanism, wherein the fitting mechanism includes:
- a first convex portion located at a first circumferential position on one of the grasping portion and the insertion portion;
- a second convex portion located at a second circumferential position on the one of the grasping portion and the insertion portion, wherein the second circumferential position is different from the first circumferential position;
- a first hole located at the first circumferential position on the other of the grasping portion and the insertion portion, wherein the first hole is configured to fit the first convex portion;
- and a second hole located at the second circumferential position on the other of the grasping portion and the insertion portion, wherein the second hole is configured to fit the second convex portion, wherein the insertion portion includes a bending portion and a plurality of wires configured to bend the bending portion, and wherein the plurality of wires is disposed at a circumferential position of the insertion portion and, when the first convex portion fits the first hole and the second convex portion fits the second hole, the circumferential position of the insertion portion corresponds to the first circumferential position and to the second circumferential position.
A connection portion of a grasping portion and an insertion portion of an endoscope, comprising:
- a fitting mechanism, wherein the fitting mechanism includes:
- a first convex portion located at a first circumferential position on one of the grasping portion and the insertion portion;
- a second convex portion located at a second circumferential position on the one of the grasping portion and the insertion portion, wherein the second circumferential position is different from the first circumferential position;
- a first hole located at the first circumferential position on the other of the grasping portion and the insertion portion, wherein the first hole is configured to fit the first convex portion;
- and a second hole located at the second circumferential position on the other of the grasping portion and the insertion portion, wherein the second hole is configured to fit the second convex portion, wherein a position of the first hole in a longitudinal direction of the grasping portion is a first hole position, wherein a position of the second hole in the longitudinal direction is a second hole position, and wherein the first hole position is different from the second hole position.
