Abstract
A high-frequency treatment apparatus has a high-frequency treatment tool having, at its distal end portion, a treatment portion for coagulating or incising tissue. A high-frequency output power supply unit is electrically connected to the high-frequency treatment tool to selectively generate a high-frequency coagulation output for coagulating tissue and a high-frequency incision output for incising the tissue on the basis of a signal generated upon manipulating a manipulation portion. The manipulation portion has a control mechanism for causing the high-frequency treatment tool to incise tissue after coagulation of the tissue by the high-frequency treatment tool is completed.
