    摘要： A microwave energy delivery and measurement system including a microwave energy source configured to delivery microwave energy, a measurement system, a switching network configured to connect the microwave energy delivery device between the microwave energy source and the measurement system, a tuner connected between the switching network and the microwave energy delivery device and a control system. The tuner adjusts the circuit impendence of the microwave energy delivery device based on a tuner control signal. The control system is configured to receive data from the measurement system, determine an impedance mismatch between the microwave energy delivery device and the microwave energy source and provide the control signal to the tuner. The measurement system includes an analog input configured to receive a first signal related to the energy delivered by the microwave energy source and an analog output configured to produce a second signal configured to drive the microwave energy delivery device. A parameter of the second signal is related to a property of the microwave energy delivery device.

    摘要： An surgical instrument configured to concurrently dissect and coagulate tissue. In an embodiment, the surgical instrument comprises a handle and a shaft extending distally from the handle. The shaft includes an outer hypotube, a lumen coaxially-disposed within the hypotube and extending beyond a distal end thereof, a coaxial feedline coaxially-disposed within the lumen, and having an inner conductor and an outer conductor disposed coaxially about the inner conductor, and a coolant tube coaxially-disposed between the lumen and the coaxial feedline to form an inflow conduit and an outflow conduit. The instrument further includes a dissecting head assembly coupled to a distal end of the shaft. The dissecting head assembly includes a dielectric core having a substantially planar radiating surface and at least one non-radiating surface, a reflective coating disposed on the at least one non-radiating surface of the dielectric core, and a blade extending from the radiating surface.
