Abstract:
Systems and methods for grip adjustment during energy delivery include an instrument comprising an end effector having a first jaw and a second jaw. Each of the first jaw and the second jaw have a corresponding electrode, The systems and methods further include one or more control units configured to actuate the end effector to grip a material, determine whether a force or torque limit of the actuation is above a first threshold, in response to determining that the force or torque limit is above the first threshold, reduce the force or torque limit, and apply electrical or thermal energy to the material using the electrodes. In some embodiments, the one or more control units are further configured to restore the force or torque limit after application of the electrical or thermal energy to the material is complete. In some embodiments, the force or torque limit is reduced over time.
