Various systems and methods for controlling the activation of energy surgical instruments are disclosed. An advance energy surgical instrument, such an electrosurgical instrument or an ultrasonic surgical instrument, can include one or more sensor assemblies for detecting the state or position of the end effector, arm, or other components of the surgical instrument. A control circuit can be configured to control the activation of the surgical instrument according to the state or position of the components of the surgical instrument.

Activation of energy devices

A surgical system includes an electrosurgical tool configured to be releasably coupled to a surgical robotic system having a control system. The tool has a shaft having an end effector with treatment electrodes configured to apply electrosurgical power to a tissue, and aspiration and irrigation tubes having ports in the vicinity of the electrodes. The control system can control a flow rate of an irrigation fluid based on deviation of power delivered by the electrodes to the tissue from a power set point, or based on an aspiration rate that is controlled based on tissue impedance. The tool can have first and second ports and a conduit configured to selectively provide or aspirate fluids through at least one of the ports. At least one of a flow rate and an aspiration rate are controlled by the control system based on a rotational angle of the shaft relative to a ground.
