摘要： An electrocautery probe includes a pair of arms between which a roller electrode is mounted. The arms are joined at their proximal ends to an electrode lead and a mounting sleeve is provided intermediate of the arms and the lead for slideably coupling the probe to a resectoscope. According to the invention, the roller electrode has an eccentric convex or concave surface to increase the surface area of the electrode. In other embodiments of the invention the electrode is provided with a plurality of longitudinal surface grooves which further increase surface area of the electrode and also enhance traction of the electrode. The electrodes according to the invention are preferably made of copper, chromium cobalt, or carbonless stainless steel. They preferably have an overall diameter of from about 0.115 to about 0.187 inches and an overall length of from about 0.110 to about 0.120 inches.

摘要翻译： 电灼探针包括一对臂，在其之间安装有辊电极。 臂在其近端处连接到电极引线，并且安装套筒设置在臂和引线的中间，用于将探针可移动地耦合到电镜。 根据本发明，辊电极具有偏心的凸面或凹面以增加电极的表面积。 在本发明的其它实施例中，电极设置有多个纵向表面凹槽，其进一步增加电极的表面积并且还增强电极的牵引力。 根据本发明的电极优选由铜，铬钴或无碳不锈钢制成。 它们优选具有约0.115至约0.187英寸的总直径和约0.110至约0.120英寸的总长度。
