In an example, an electrode includes an elongated body, a conductive layer, and an insulator layer. The elongated body includes a first conductive material and extends in an axial direction from a proximal end to a distal end. The proximal end is configured to receive electrosurgical energy from the electrosurgical tool. The elongated body includes a blade for at least one of cutting or coagulation of tissue by the electrosurgical energy received from the electrosurgical tool. The conductive layer includes a second conductive material coupled to the blade of the elongated body. The second conductive material is different than the first conductive material. The insulator layer includes a non-conductive material and is coupled to the conductive layer. The insulator layer covers a first portion of the conductive layer, and does not cover a second portion of the conductive layer such that the conductive layer is exposed at the second portion.

Electrosurgical electrodes, electrosurgical tools, and methods of making electrosurgical electrodes

An electro-surgical pencil comprising: a housing forming an axially extending main suction passage from a proximal opening to a distal opening; a tube forming an extension of the main suction passage from the proximal opening to a proximal extension opening, the tube being configured for telescoping movement through the proximal opening; an electrode for cutting and/or coagulating tissue, the electrode being attached to the tube and extending axially from the proximal extension opening; and a suction tip attached to the tube and forming a further extension of the suction passage. Since both the tube and the suction tip are movable relative to the housing, a short and a long configuration can be obtained while good smoke removal capabilities are maintained.

Electrosurgical pencil

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.
