Systems, such as an electrosurgical unit, and method for use with an active electrode and a plurality of return electrodes are disclosure. An electrosurgical treatment is provided to tissue via the active electrode at a treatment site and a first return electrode of the plurality of return electrodes at the treatment site. An impedance measurement is received or determined of an impedance in the tissue between the active electrode at the treatment site and a second return electrode of the plurality of return electrodes at a site remote from the treatment site.

Electrosurgical unit and system

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.

Surgical instrument and system

Embodiments relate to illuminated electrosurgical devices and related systems and methods. An electrosurgical device can include an electrosurgical blade having a proximal end and a distal end and comprising a plurality of light elements. A plurality of separation walls and a plurality of apertures can be arranged relative to the plurality of light elements to guide light from the plurality of light elements to illuminate an area around the distal end of the electrosurgical blade.
