Abstract: Systems and methods of controlled grasping and energy delivery include a computer-assisted device. The computer-assisted device includes an end effector and one or more processors. The end effector includes a first jaw, a second jaw, and a plurality of electrodes for delivering energy. The one or more processors are configured to grasp a material using the first jaw and the second jaw, determine characteristics of the grasp, determine characteristics of the material, and control one or more of the grasp or energy delivery by the plurality of electrodes based on the determined characteristics of the grasp and the determined characteristics of the material. According to some embodiments, the characteristics of the material include one or more of thermal, dielectric, or stiffness of the material. In some embodiments, the characteristics of the grasp include one or more of applied pressure, jaw angle, jaw separation, force, torque, or wrist articulation.

Abstract: An electrode assembly may include an electrode support made of a first electrically insulative material and an electrode on the electrode support, the electrode having a working surface extending generally transverse to a thickness of the electrode. The electrode assembly may further include an insulative spacer retained in the electrode and made of a second electrically insulative material. The second electrically insulative material may be different from the first electrically insulative material. The insulative spacer of the electrode assembly may have a body portion extending into the thickness of the electrode, and a head portion protruding beyond the working surface of the electrode.
