  • Electrosurgical instrument
    Patent number: 9283032
    Abstract: An electrosurgical instrument for the treatment of tissue in the presence of an electrically-conductive fluid medium comprises an instrument shaft (10), and an electrode assembly (12) at one end of the shaft. The electrode assembly (12) comprises a tissue treatment electrode (14) and a return electrode (18) which is electrically insulated from the tissue treatment electrode by means of an insulation member (16). The tissue treatment electrode (14) has an exposed surface for treating tissue, and the return electrode (18) has a fluid contact surface so as to define, in use, a conductive fluid path that completes an electrical circuit between the tissue treatment electrode and the return electrode.
