Peripheral switching device for microwave energy platforms
An electrosurgical system includes a power source, a microwave applicator, a switching mechanism, and a controller. The power source is configured to generate microwave energy. The microwave applicator is configured to deliver microwave energy from the power source to tissue. The switching mechanism includes a housing having input and output ports. The input port is connectable to the power source and the output port is connectable to the microwave applicator. The housing is configured to house one or more switches therein. The controller is in operative communication with the switching mechanism to toggle the switch from a first state, wherein microwave energy generated by the power source is directed to the microwave applicator to a second state, wherein microwave energy is directed to a resistive load operably coupled to the switching mechanism.
