Abstract:
1. An electrosurgical handpiece for manipulating an electrosurgical fiber electrode for treating tissue, comprising: (a) an elongated first tubular member having a major longitudinal axis and having a proximal first end and a distal second end and containing an inner channel for receiving a wire electrode comprising a long thin flexible electrically-insulated wire having an active distal end, (b) a deflector tip mounted for pivotal movements on the distal second end of the first tubular member, the deflector tip having at least one hole through which the distal end of the wire electrode can pass and be exposed when inserted through the channel, (c) a handle connected to the first tubular member, the handle having a movable part, (d) means connecting the movable part of the handle to the deflector tip such that movements of the movable part of the handle are transmitted to the deflector tip causing the distal end of the wire electrode when inserted through the channel to extend in different orientations with respect to the longitudinal axis of the first tubular member, (e) further comprising a suction port for receiving external suction coupled to the inner channel of the first tubular member, the deflector tip further comprising additional openings such that any suctionable material arising from the treated tissue can be suctioned away via the inner channel and suction port.
