    摘要: Systems and corresponding methods for determining characteristics of an output signal generated by a high-frequency medical device using low-frequency measurement systems are disclosed. A digital measurement system includes an oscillator, a mixer, and a controller coupled to each other. The oscillator provides a reference signal having a second frequency. The mixer generates a down-converted signal based on the output signal and the reference signal. The controller then determines a characteristic of the output signal (e.g., frequency or phase) based on the down-converted signal. An analog measurement system includes a filter having a center frequency, a rectifier, and a controller. The filter filters the output signal and the rectifier rectifies the filtered signal. The controller samples the rectified signal and determines a characteristic of the output signal based on the level of the rectified signal. The reference signal controller may adjust a characteristic of the output signal based on the determined frequency and/or phase of the output signal.

    摘要: The present disclosure provides for an end effector assembly for microwave forceps. The end effector assembly includes a pair of opposing jaw members movable from a first position in spaced relation relative to one another to at least one subsequent position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members includes a microwave antenna assembly and a shielding member including a metallic plate coupled to ground and a dielectric material. The end effector assembly also includes a splitter configured to receive an active signal from a source of microwave energy and split the active signal into a first signal transmitted to the microwave antenna assembly in one of the jaw members and a second signal transmitted to the microwave antenna assembly in the other jaw member.
