Abstract: Provided is a scissors-type medical treatment tool capable of not only local tissue fixation in an incision/cutting part but also heating on side surfaces of electrodes of a forceps/tweezers type. It has been found out that a tissue part in which tissue is nipped between blades and a tissue part which is brought into abutment against side surfaces of the blades can be heated simultaneously or sequentially by optimizing arrangement of microwave application electrodes and microwave receiver electrodes in a blade pair (in particular, by causing coagulation to be performed evenly on the left and right of the blades), and the present invention has therefore been achieved.

Abstract: A bending and extending device 1 comprises an elastic hollow guide unit 2 and a movable part 3 to be movably inserted into the guide unit 2. The movable part 3 is constituted, either partially or entirely, of a plurality of belt-like flexible parts 30a and 30b, which extend in the axial direction of the guide unit 2 and the flexible parts 30a and 30b are connected at distal ends. The bending and extending device 1 is characterized in that, when, by the sliding operation of the flexible parts 30a and 30b, a cross-section in which a contact point T of the flexible part 30a and the inner surface of the guide unit 2 is present on an extending line Y extending from a line segment connecting the centroid P of the flexible part 30b and the axial center G of the guide unit 2 and in which the flexible part 30a and the second flexible part 30b are in contact with each other is generated, and when the cross-section is divided into two ranges by a predetermined straight line X, the centroid P of the flexible part 30b is not positioned in a range in which the contact point T is present; and the predetermined straight line X is a line that passes through the axial center G of the guide unit 2, and that orthogonally crosses the extending line Y.
