Patent attributes
An electrode assembly for an electrosurgical instrument includes a housing configured to operably receive a distal end of an instrument shaft, the housing including a pair of opposing spring clips. An active electrode is included having a proximal end configured to engage the distal end of the shaft and includes a cutting edge defined about a periphery thereof. An insulator is included that encapsulates the active electrode while leaving the cutting edge exposed. A pair of return electrodes is included that is each configured to operably engage an exposed side of the insulator, each return electrode including a recess defined therein configured to removably receive a distal end of each respective spring clip such that, upon selective engagement of the active electrode with the distal end of the shaft, each spring clip removably snaps into each respective recess to removably lock the active and return electrodes to the housing.
