Abstract: An electrosurgical apparatus with a retractable blade for use in cold plasma applications, electrosurgical cutting and mechanical cutting is provided. The electrosurgical apparatus employs a tip of the retractable blade as a sharp conductive point to generate a plasma beam or discharge. When the blade is retracted within the electrosurgical apparatus, it is electrically energized while an inert gas flows over it, producing a cold plasma discharge. In the de-energized state, the blade is advanced and used as a traditional, mechanical surgical blade.

Abstract: An apparatus for use with an endoscopic applicator. The apparatus including a support member configured to be removably coupled to a shaft of the applicator; a first sensor disposed on the distal end of the support member and for outputting a first signal indicative of current measured at the distal end of an active electrode supported in the shaft; and a second sensor disposed on the proximal end of the support member and for outputting a second signal indicative of current measured at the proximal end of the active electrode, wherein a difference value of the first and second signal is indicative of leakage of current within the shaft. In one embodiment, the first and second sensors are magnetic sensors for contactlessly sensing parameters of the active electrode.
