Abstract
A grooved roller forming part of an electrode for use with a resectoscope is shown. The electrode includes an electrode lead member having an elongated conductor member. The elongated conductor member has a first end and a second end with an insulative cover extended therebetween. The first end has a protruding electrode adapted to be electrically connected to an electrosurgical generator and the second end terminates in an active member. An electrode support member is operatively connected to the active member. The electrode support member has an elongated semi-rigid bifurcated arm terminating in a conductive core spaced a predetermined distance from the active member. The bifurcated arm is covered with an insulative material except at the distal end where the grooved roller is located. The electrode support member has a grooved roller having a central opening extending therethrough for rotatably mounting the grooved roller on the conductive core of the support member. A method for treating and vaporizing tissue, such as prostate tissue, using the grooved roller electrode for a resectoscope is also shown.
