Peripheral switching device for microwave energy platforms

摘要

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.

1. An electrosurgical system, comprising:
a power source configured to generate microwave energy; a microwave applicator configured to deliver microwave energy from the power source to tissue; a switching mechanism configured to be coupled with the power source and the microwave applicator and including at least one switch, wherein the at least one switch is at least one of an absorptive/reflector pin diode attenuator, a digital programmable step attenuator, or a single pole dual throw switch; a resistive load operably coupled to the switching mechanism; and a controller configured to toggle the switching mechanism between a first state, wherein the switching mechanism directs microwave energy generated by the power source to the microwave applicator, and a second state, wherein the switching mechanism directs microwave energy to the resistive load.
