摘要:
An electrode for an electrosurgical pencil, the electrode comprising an elongated body made of a conductive material and extending in an axial direction from a proximal end to a distal end, the proximal end configured for engaging the electrosurgical pencil and the distal end forming a blade configured for cutting or coagulation of tissue by electrosurgical energy received from the pencil, the blade being defined by two main surface portions on opposite sides of an axially extending intermediate plane and joined by an edge extending through the intermediate plane. To concentrate electrical energy at the edge and thereby facilitate a more precise cutting and less burnt tissue sticking to the electrode, the main surface portions has a first surface roughness, the edge has a second surface roughness being lower than the first surface roughness, and at least the main surface portions are covered by a surface coating comprising silicone.
