In an energy control device, a processor detects, based on a detection result of an electric characteristic value in relation to an electric energy which is output from an energy output source to an ultrasonic transducer, a gradual decrease start time at which the electric characteristic value starts a gradual decrease after a gradual increase. The processor executes, based on a fact that a time rate of change of the electric characteristic value become greater than a predetermined threshold after the gradual decrease start time, at least one of causing the energy output source to stop or reduce the output of the electric energy to the ultrasonic transducer, and notifying that the time rate of change become greater than the predetermined threshold.

An electrosurgical system including or connected to an output circuitry comprising an electrosurgical device and an electrical cable is modelled during a cable interrogation phase using a transfer matrix in order to determine a leakage capacitance in the electrosurgical system. After the leakage capacitance is assigned or set to a virtual capacitor in the transfer matrix, an output parameter of the electrosurgical system, such as output voltage, output current, output impedance or output electrical power, may be determined by applying an actual input voltage to the output circuitry and measuring a resulting input current, and multiplying the input voltage and measured current by the transfer matrix.

Various aspects of the present disclosure provide for coordinated operation of surgical instruments accessing various surgical sites from different or shared surgical approaches to achieve a common or cooperative surgical purpose. For example, various methods, devices, and systems disclosed herein can enable the coordinated treatment of tissue by disparate minimally invasive surgical systems that approach the tissue from varying anatomical spaces and must operate differently, but in concert with, one another to effect a desired surgical treatment.
