Abstract
A temperature regulating patient return electrode and return electrode monitoring system for use in monopolar surgery, includes a positive temperature coefficient (PTC) material disposed on its surface. The PTC material responds to local increases in temperature by increasing local resistance. This quality decreases the probability of a patient burn as a result of monopolar surgery. The return electrode monitoring system includes a generator for generating current; an active electrode coupled to the generator for supplying the current to a patient; and a return electrode coupled to the generator with a surface for receiving the current from the patient and returning the current to the generator. A positive temperature coefficient (PTC) material is disposed on the return electrode for regulating the temperature over the surface of the return electrode.
