    摘要： An ablation instrument having an ergonomic handle that includes an actuator adapted to selectively extend and retract a blade that is pivotably mounted within an aperture assembly coupled to the housing by a shaft. The shaft extends distally from the handle and includes a coaxial feedline, a wire conduit disposed along a longitudinal axis of the shaft, and a pull wire disposed within the wire conduit and having a proximal and a distal end, wherein a proximal end of the pull wire is operably coupled to the actuator. The aperture assembly is coupled to a distal end of the shaft and includes a reflector having a closed upper portion, and an open lower portion from which the blade may be extended for use. Also disclosed is an ablation system that includes the above-described ablation instrument, a source of ablation energy, and optionally, a source of coolant for cooling the shaft and aperture assembly.

    摘要： An electrosurgical system is provided and 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.
