Abstract

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 (10), a tissue treatment electrode (12) at one end of the shaft, and removal means, the instrument having an apertured portion (20a) 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 (10) and leading from the apertured portion (20a). The channel is provided with agitation means (14) for preventing the build-up of sublimation products within the channel.
