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: 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: A surgical robotic arm includes an instrument having a coupler rotatable about a longitudinal axis, the coupler including: a drive screw; a drive nut threadably coupled to the drive screw, the drive nut movable along the longitudinal axis in response to rotation of the drive screw; and a drive member coupled to the drive nut and movable in response to movement of the drive nut. The surgical robotic arm also includes an instrument drive unit having: a motor configured to engage the coupler and rotate about the longitudinal axis to rotate the coupler and the drive screw; one or more sensors configured to measure one or more properties of the motor; and a controller coupled to the sensor(s) and the motor. The controller is configured to control the motor based on the property of the motor.
