  • Electrosurgical device with multiple monopolar electrode assembly
    Patent number: 10716612
    Abstract: An electrosurgical device having a handpiece including a controller and an electrode assembly extending from the handpiece is disclosed. The electrode assembly includes a monopolar blade and a monopolar electrode. The monopolar blade includes a conductive element partially coated with an insulator and electrically coupled to the controller to selectively deliver a monopolar radiofrequency (RF) cutting signal. The monopolar electrode is spaced apart and electrically isolated from the monopolar blade. The monopolar electrode includes an exposed major conductive surface electrically coupled to the controller to selectively deliver a monopolar RF hemostatic sealing signal with a dispersed fluid.
    Type: Grant
