Universal foot switch contact port

A universal contact port for use in an electrosurgical generator, the contact port comprising:

• A ring gear having a circular rim formed therein and defining a central rotational axis, the rim including a series of teeth formed therearound;
• A plurality of spur gears operatively engaged with the rim of the ring gear, each spur gear defining a longitudinal axis which is at least substantially parallel with the central rotational axis;
• and
• At least three rollers operatively associated with a respective spur gear, each roller of the at least three rollers defining a corporal axis, the corporal axis of each roller of the at least three rollers being parallel to an spaced from the longitudinal axis of the respective spur gear, the at least three rollers defining an opening therebetween, wherein the opening is constricted by rotation of the ring gear in a first direction about the central rotational axis and expanded by rotation of the ring gear in a direction opposite to the first direction;
• A plurality of shafts, each shaft of the plurality of shafts configured for eccentrically supporting a respective one of the at least three rollers, wherein the shafts of the at least three rollers are equally spaced from one another,
• wherein each shaft of the plurality of shaft includes a first end operatively associated with a respective spur gear and a second end operatively associated with the electrosurgical generator,
• wherein the opening is at a minimum when the at least three rollers are in contact with one another and wherein the opening is at a maximum when the corporal axes of the at least three rollers are positioned radially outward of the longitudinal axes of the shafts relative to the central axis of the ring gear,
• wherein the at least three rollers are fabricated from electrically conductive material.
