An electrosurgical instrument is provided for the treatment of tissue in the presence of an electrically-conductive fluid medium. The instrument comprises an instrument shaft ( ), a tissue treatment electrode ( ) at one end of the shaft, and removal means, the instrument having an apertured portion ( ) through which matter can be aspirated by the removal means from the region surrounding the tissue treatment electrode. The removal means comprises a channel formed within the instrument shaft ( ) and leading from the apertured portion ( ). The channel is provided with agitation means ( ) for preventing the build-up of sublimation products within the channel.

Electrosurgical instrument

An electrosurgical instrument is provided for the treatment of tissue in the presence of an electrically-conductive fluid medium. The instrument comprises an instrument shaft ( ), and a tissue treatment electrode ( ) at the distal end of the shaft for electrosurgically excising tissue pieces at an operation site. The tissue treatment electrode ( ) is cyclically movable relative to the distal end of the shaft ( ). Threshold control means are provided for controlling the power threshold for vaporisation of the electrically-conductive fluid medium at the tissue treatment electrode ( ).
