Abstract
An endoscope system of the disclosure includes an endoscope including an insertion section, and a coupling thread extending along the insertion section. The coupling thread includes a coupling portion at a distal end of the coupling thread, and a thread portion extending proximally from the coupling portion. The endoscope system includes a distal end cover on a distal end portion of the insertion section. At least a part of the distal end cover moves on an outer surface of the distal end portion. The distal end cover partially covers the coupling portion.

An endoscope system, comprising:
- an endoscope;
- and
- an endoscope attachment,
- wherein the endoscope attachment includes:
- a distal end cover configured to be attached on a distal end portion of an insertion section of an endoscope, and
- a coupling thread configured to move between a first state and a second state,
- wherein the coupling thread includes;
- a coupling portion at a distal end of the coupling thread, and
- a thread portion extending proximally from the coupling portion,
- wherein the distal end cover is attached on to the distal end portion of the insertion section of the endoscope,
- wherein the distal end portion includes a groove,
- wherein, in the first state;
- a distal portion of the coupling portion contacts an inner circumferential surface of the distal end cover, and
- the distal portion of the coupling portion is attached to the groove,
- wherein the distal end cover includes a slit having a first length,
- wherein a length in a longitudinal axis direction that the distal portion of the coupling portion is attached to the distal end portion of the insertion section defines a second length, and
- wherein the first length is equivalent to or greater than the second length.
