Abstract: A surgical device to deliver energy to tissue can include a hand piece and a shaft. The hand piece can be operable to control the surgical device. The shaft can extend along a longitudinal axis and the shaft can include a proximal portion and a distal portion opposite the proximal portion. The proximal portion can be connected to the hand piece. The device can include an end effector connected to the distal portion of the shaft. The end effector can include an active electrode, an insulator at least partially surrounding the active electrode, and a return electrode adjacent the insulator. The device can include a heat pipe connected to the return electrode and extending at least partially through the shaft. The heat pipe can be configured to transfer heat from the return electrode to the hand piece.
