Patent ID: 8157798

Claim:
A treatment tool for an endoscope comprising: a treatment portion that is positioned on a distal end side and of which at least a portion is formed from an electroconductive material; an operating wire that is formed from an electroconductive material and is connected to the treatment portion; a sheath that is formed from an electrically non-conductive material through which the operating wire is inserted; a base being comprised of a base main body having a connecting arm, the base being fixed to a base end side of the sheath so as to be orthogonal to an axis line of the sheath by means of the connecting arm; an operating section being provided with an operating section main body that is rotatably attached to the base main body and to a slider that is attached to the operating section main body so that the slider can move forwards or backwards relative to the operating section main body, and a base end side of the operating wire that is connected to the slider, the operating section causing the treatment portion to move forwards and backwards and to rotate via the operating wire; and a plug that is provided on the base main body and is electrically connected to the operating wire, wherein the slider is attached to the operating section main body so that a direction in which the slider moves is orthogonal to an axis line which connects the base and the axis line of the sheath and so that an axis line along the direction in which the slider moves and the axis line of the sheath form skew axis lines.
