Abstract

An endoscopic treatment device has a sheath extending between a distal end portion and a proximal end portion; a first/second wire inserted through the sheath, wherein the first/second wire can protrude from the distal end portion of the sheath and cut tissue by being applied with current; an insulative member configured to connect distal ends of the first wire and the second wire; and a first/second insulative tube configured to cover the first/second wire protruding from the sheath, wherein the first/second insulative tube can move with respect to the first/second wire respectively, wherein the endoscopic treatment device switches between a first state where the second wire protruding from the sheath is covered by the second insulative tube and a second state where the first wire protruding from the sheath is covered by the first insulative tube.
