Endoscope system, endoscope system control program, and endoscope system control method

An endoscope system comprising:

• a first elongate member inserted into a subject;
• a first shape-holding section provided on the first elongate member and capable of switching at least part of the first elongate member between a flexible and deformable first state and a shape-held second state;
• a conduit which, being provided on the first elongate member, communicates a proximal opening and a distal opening of the first elongate member;
• a second elongate member which is inserted through the proximal opening, passed through the conduit in such a way that a distal end of the second elongate member can stick out of the distal opening, and movable relative to the first elongate member in a direction of the passage;
• a second shape-holding section provided on at least part of the second elongate member in such a way as to include at least part of a portion which can stick out of the distal opening and capable of switching the at least part of the second elongate member between a flexible and deformable first state and a shape-held second state;
• and
• fixing means which, being provided at the distal end of the second elongate member, fixes the second elongate member to the subject by abutting the subject.
