Abstract
A high frequency treatment tool for an endoscope includes a flexible insulating tube to be inserted into and pulled out of an accessory channel of the endoscope, the flexible insulating tube including a wire insertion channel and a water channel through which water is conveyed, a conductive wire configured to move back and forth in an axis line direction thereof through the wire insertion channel, and an electrode configured to project and recede from a distal end of the flexible insulating tube. The wire insertion channel and the water channel are separately formed in an axis line direction of the flexible insulating tube such that each of axis lines of the wire insertion channel and the water channel is eccentric with respect to the axis line of the flexible insulating tube. The electrode is coupled to the conductive wire such that an axis line of the electrode is eccentric with respect to an axis line of the conductive wire.
