Abstract
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.
