Abstract: A marker to be attached to an endoscopic treatment tool for precisely directing a tip of the treatment tool to a target site with no additional physical burden to the patient is provided. A marker 1 used in an endoscopic treatment tool to be inserted in a guide sheath, the marker including: a body 2; and a tip section 4A for removably fixing the body 2 to a middle section of the endoscopic treatment tool, wherein the distance between the body 2 and a tip of the endoscopic treatment tool can be determined freely.

Abstract: A charger of the present invention may include a plurality of battery connection parts to which battery packs can be connected to charge, with each battery connection part having an indicator. The indicators may be configured such that when charging is expected to be completed more quickly in a first battery connection part compared to a second battery connection part, the indicator of the first battery connection part is displayed differently from the indicator of the second battery connection part.

Abstract: Provided is a treatment tool including: an elongated member which is formed of a flexible material and includes first and second terminals; a first body portion which is fixed to the first terminal so as to function in a target; a handle portion which is provided in the second terminal and is provided with a rotating holding portion holding the elongated member so as to be rotatable about the axis of the elongated member; and a second body portion which is attached to the handle portion so as to function in a target and is rotated relative to the elongated member when rotating the handle member relative to the elongated member. The treatment tool is capable of performing a cleaning treatment or the like while curtailing extraneous matter from being scattered in the vicinity thereof and reducing contamination thereof.
