Abstract
An electrode assembly for a resectoscope includes, a cutting electrode with a loop distal tip and a coagulation electrode with a loop distal tip. A support frame connects the cutting and coagulation electrodes to an energy source which supplies energy from the energy source to the electrodes. The coagulation electrode provides tissue coagulation simultaneously while the cutting electrode cuts tissue. A resectoscope is disclosed which includes the electrode assembly. The resectoscope includes a sheath with a sheath lumen, a working element, and a visualization apparatus.
