Abstract
The present disclosure provides an electrosurgical return pad current detection system for use in monopolar surgery as well as a method of using the same. The detection system comprises a plurality of conductive pads which include a plurality of conductive elements. The detection system further includes a sensor which senses the current returning to each conductive pad as well as a comparator which determines the difference in current among a plurality of conductive pads. If the current differential is above or below a prescribed limit, the system will alert the user of potential hazards and/or alter the amount of energy delivered to a surgical device.
