Abstract

An electrosurgical system includes an electrosurgical unit electrically coupled to a surgical retractor. The electrosurgical unit includes an RF output and an RF return. The surgical retractor includes a return pad electrically coupled to the RF return of the electrosurgical unit. The electrosurgical unit includes an RF output configured to be coupled to an electrosurgical device, such as an electrosurgical device configured in a monopolar mode. A controller is configured to determine an impedance in tissue at a surgical area electrically disposed between the RF output and the and the RF return. The surgical retractor includes a handle and a blade configured to interface with tissue. The blade includes a return electrode.
