Реферат: An adapter unit for a mechanical tissue cutting implement such as a shaver, includes a mounting block (222) from which an electrically insulating sheath (206) extends. The sheath fits over the shaft of the cutting implement (154), is secured in alignment, attached so that the cutting tip, and its window (214) are exposed through the sheath. A conductor (208) extends along the length of the sheath, and is exposed to form a distal electrode, at the tip in close proximity to the opening, constituting one electrode of a bipolar electrode arrangement at the exposed tool. The other electrode is provided by electrical connection to the implement itself, so that a high current density path is formed through tissue in the cutting region. Preferably both output connections of an electro-surgical generator are coupled through a matching transformer (252) to the mounting block by a plug, socket, cable or fixed cord arrangement.
