Abstract
An electrode assembly for an electrosurgical instrument has an elongate tubular shaft with electrodes mounted on a distal end and, on a proximal end of the shaft, means for detachably mounting the assembly in a handpiece of the instrument. Electrical conductors pass through the shaft from the electrodes to contacts on the mounting means which are located so as to make a connection with a radio frequency source. The mounting means takes the form of a housing shaped for attachment to the handpiece in a non-rotational relationship and, rotatably located within the housing, a sleeve which is fixed to the shaft. The conductors terminate in contact portions secured in the housing of the mounting means and are so formed as to allow the electrodes, the shaft, parts of the conductors in the distal end portions, the shaft, and the sleeve to rotate with respect to the housing and the contact portions about the axis of the shaft.
