First Claim
Patent Images
1. An electrosurgical system for measuring contact quality of a return pad, comprising:
- a return pad having a backing layer, comprising;
at least one capacitive return electrode disposed on the bottom side of the backing layer, the at least one return electrode being adapted to connect to a return interface; and
at least one ring sensor disposed on the at least one capacitive return electrode and in substantial concentric registration with the periphery of the at least one capacitive return electrode, the at least one ring sensor configured to connect to a sensing interface;
a return interface adapted to return current from the at least one capacitive return electrode; and
a sensing interface configured to monitor an impedance associated with the at least one capacitive return electrode to determine contact quality.

Abstract
A return pad includes a backing, at least one return electrode, and at least one ring sensor. The backing has a top side, a bottom side, and a periphery. The return electrode is disposed on the bottom side of the backing layer and is adapted to connect to a current generator. The ring sensor(s) is disposed in substantial concentric registration with the periphery of the backing and is configured to connect to a measuring component. The measuring component is operable to approximate contact quality of the return electrode during electrosurgical application and is configured to communicate with the generator.
