Abstract: An endoscope snare includes a sheath, a support wire inserted into the sheath and movable advance and retraction in the sheath along an axis, a loop-shaped conductive wire connected to a distal end of the support wire, and a pressing wire inserted into the sheath, connected to the conductive wire at a position different from that of the support wire, and movable advance and retraction in the sheath independently of the support wire. The pressing wire may have a plurality of wires, and may be connected to at least the conductive wire at two points of the support wire between which the axis is interposed.

Abstract: An electrode unit which performs treatment on tissue in a subject by using a high frequency current under observation with an endoscope includes: two electrode support members disposed in a separated manner in a direction along a predetermined axis; a base part extending along an axis intersecting with the predetermined axis, and having a distal end coupled with proximal ends of the two electrode support members; and an electrode having both ends supported by the two electrode support members, wherein the electrode includes an exposed portion in a region which overlaps with at least one of the two electrode support members when viewed from a second direction which is opposite to a first direction in which the two electrode support members are pushed against the subject during use of the electrode unit, the exposed portion being exposed only in the second direction.
