摘要：
What is disclosed is an endoscopic surgical instrument with a hose-shaped outside jacket, in which a likewise hose-shaped inside jacket is supported relatively displaceable, on whose distal end section a sleeve or shaft-shaped instrument head is formed or mounted. In the instrument head is fixed a needle-shaped RF electrode electrically-insulated, whose electrical supply line is routed through the inside jacket, and which projects freely beyond the distal end of the instrument head in the axial direction. In the instrument head is formed a flush channel, extending at least axially, opening at both instrument head ends.
