Method for washing treatment tool stand

A method for washing a treatment tool stand of an endoscope, using a stand washing tool having

• a handle having a distal end, a proximal end, and a longitudinal axis,
• a head provided on a distal end side of the handle,
• a first washing member erected in a direction intersecting a reference plane including the longitudinal axis on the head, and
• a second washing member erected in a direction intersecting the reference plane on the head closer to the handle than the first washing member and provided so as to be parallel to or coincide with the first washing member in a case where the second washing member is projected on a plane perpendicular to the longitudinal axis,
• wherein the first washing member has a first end opposite to one end on the head side,
• wherein the second washing member has a second end opposite to one end on the head side,
• wherein a height position of the first end in a direction orthogonal to the reference plane from the reference plane is a first height position,
• wherein a height position of the second end in the direction orthogonal to the reference plane from the reference plane is a second height position lower than the first height position, the washing method comprising:
• a first washing member inserting step of inserting the first washing member into a gap between a stand storage wall section of the endoscope and the treatment tool stand;
• a second washing member abutting step of making the second washing member abut against a back surface opposite to a treatment tool guide surface of the treatment tool stand;
• and
• a stand washing tool moving step of moving the stand washing tool along the back surface in a state where the first washing member is inserted into the gap and the second washing member is made to abut against the back surface.
