PROBLEM TO BE SOLVED: To minimize a restriction applied to an observation field of view, to secure a broad observation field of view and to improve the safety and operability of an operation by a high-frequency treatment instrument in mucosal dissection for dissecting a submucosal layer located in the lower part of the incised mucosa.
SOLUTION: When dissecting mucosa after incising the mucosa with a high-frequency knife 13 of the high-frequency treatment instrument 1, which is inserted in a treatment instrument insertion channel 27 of an insertion section 22 of an endoscope 20, a pressure fluid is supplied to the interior of a flexible bag 33 of a retractor member 31 to curve an elastic plate piece 32 in the direction of separating from the axial center of the insertion section 22 and lift the mucosa.
