Abstract: In an example, a monopolar electrosurgical electrode includes an electrosurgical substrate including an electrically conductive material extending in an axial direction from a proximal end to a distal end. The electrosurgical substrate includes an electrosurgical blade. The electrosurgical blade includes (i) a first lateral surface, (ii) a second lateral surface opposite the first lateral surface, (iii) a first major surface extending between the first lateral surface and the second lateral surface on a first side of the electrosurgical blade, and (iv) a second major surface extending between the first lateral surface and the second lateral surface on a second side of the electrosurgical blade that is opposite the first side. The monopolar electrosurgical electrode also includes a first electrode sensor embedded between a plurality of electrical insulation layers on the first major surface of the electrosurgical blade.

Abstract: In an example, an electrosurgical electrode for an electrosurgical tool can include a proximal end configured to receive electrosurgical energy from an electrosurgical tool and a distal end opposite the proximal end. The electrosurgical electrode can also include a cutting-electrode portion extending from the proximal end to the distal end. The cutting-electrode portion is configured for cutting tissue using the electrosurgical energy received from the electrosurgical tool. Additionally, the electrosurgical electrode can include a coagulating-electrode portion extending from the proximal end to the distal end. The coagulating-electrode portion is configured for coagulating tissue using the electrosurgical energy received from the electrosurgical tool. The electrosurgical electrode can further include an insulator between the cutting-electrode portion and the coagulating-electrode portion.

Abstract: A method of treating tissue includes clamping tissue between an ultrasonic blade and a jaw member and simultaneously: transmitting ultrasonic energy to the ultrasonic blade to vibrate the ultrasonic blade at a first blade velocity thereby heating the clamped tissue; and supplying electrosurgical energy, at a constant voltage, to the jaw member and the ultrasonic blade at different potentials such that the electrosurgical energy is conducted therebetween and through the clamped tissue to heat the clamped tissue. An impedance of the clamped tissue is monitored and the simultaneous transmission of ultrasonic energy and supply of electrosurgical energy is terminated and/or a notification is output once the clamped tissue is sealed, as indicated by the impedance of the clamped tissue being equal to or greater than a threshold impedance. Surgical instruments and end effectors thereof for treating tissue in this manner are also provided.
