ABSTRACT:
An electrosurgical system includes an electrode assembly which is detachably combined with an aspiration/irrigation cannula. The electrode assembly includes a shaft having an electrode tip at its distal end and a connector plug at its proximal end. A sleeve slidably and rotatably received on the proximal end of the shaft includes connecting means for securing to a proximal housing on the cannula. The system includes both the cannula and electrode assembly and is useful in performing electrosurgical procedures as part of minimally invasive surgical operations. A non-conductive cannula and valve housing are also provided which prevent capacitive coupling between the cannula and a monopole electrode.
