Abstract
An endoscope auxiliary instrument includes a hood, a hood cover that is provided at a distal end portion of an insertion portion of an endoscope and that movably holds the hood along an axial direction of the insertion portion, and a wire fixing portion. The wire fixing portion causes the hood to protrude/retract at the distal end portion in a direction parallel to an axis of the hood that is a direction along an axial direction of the insertion portion, and fixes a wire that, when the hood receives a force in a proximal end direction in a state in which the hood protrudes in a distal end direction of the distal end portion, generates a return force that causes the hood to returns to the protruding state.
