A universal contact port for use in an electrosurgical generator is provided and includes a ring gear having a circular rim formed therein and defines a central rotational axis. The rim includes a series of teeth formed therearound. A plurality of spur gears are 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 a plurality of rollers operatively associated with a respective spur gear, each roller defining a corporal axis. The corporal axis of each roller is parallel to and spaced from the longitudinal axis of the respective spur gear. The rollers define an opening therebetween. 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.
