摘要： A high frequency treatment apparatus of the present invention comprises a high frequency generation section for supplying high frequency power, a control section, which is connected to the high frequency generation section, and which controls output of the high frequency generation section, having a first control mode in which the maximal output value of high frequency power supplied from the high frequency generation section is confined to be equal to or less than a first predetermined value and a second control mode in which the maximal output value of high frequency power supplied from the high frequency generation section is confined to be equal to or less than a second predetermined value which is less than the first predetermined value, a treatment tool, which is connected to the high frequency generation section, and which performs a treatment of a diseased part by supplying high frequency power from the high frequency generation section controlled by the control section to the diseased part, and a control mode setting section, which is connected to the control section, for selecting one of the first and second control modes.

摘要： An hf resectoscope implement for cutting body tissue in a body cavity filled with an electrically conducting fluid and comprising a loop support and a loop-shaped cutting electrode mounted distally on the support. A plane of the cutting electrode slants relative to a longitudinal axis of the loop support. The implement also includes a neutral electrode mounted on the support. An insulator is mounted at the loop support between the electrodes such that any straight geometric line between the electrodes passes through the insulator. The neutral electrode and the insulator are configured to not significantly hamper the view available via optics fitted in the resectoscope stem tube.

摘要： A medical instrument for use in combination with an endoscope having an operating shaft and a pair of tongs. The instrument has a drive mechanism provided between the operating shaft and the tongs, for opening and closing the tongs. The drive mechanism can apply an additional force to the tongs even after the tongs have closed completely.
