ENDOSCOPE

摘要

An endoscope includes: a contact surface formed on a part of an outer circumference of a functional member; a distal end member provided on a distal end portion of the insertion portion and including a first hole portion provided with a first hole axis, in which the functional member is arranged, and a second hole portion provided with a second hole axis being orthogonal to the first hole axis and communicating with the first hole portion; and a fixing member configured to fix the functional member to the distal end member by being inserted into the second hole portion in a state that a contactless portion not being in contact with the contact surface is caused to face the contact surface, and being rotated around an axis by a predetermined angle.

1. An endoscope comprising:
an insertion portion configured to be inserted into a subject; a functional member having a predetermined function; a contact surface formed on a part of an outer circumference of the functional member; a distal end member provided on a distal end portion of the insertion portion and comprising a first hole portion provided with a first hole axis, in which the functional member is arranged, and a second hole portion provided with a second hole axis being orthogonal to the first hole axis and extending in a tangential direction relative to the contact surface of the functional member arranged in the first hole portion and communicating with the first hole portion; and a fixing member configured to generate fixing force for fixing the functional member to the distal end member by being inserted into the second hole portion in a state that a contactless portion not being in contact with the contact surface is caused to face the contact surface, and being rotated around an axis by a predetermined angle.
