摘要： An apparatus for operating on tissue includes a body, a shaft, an ultrasonic blade, and an acoustic assembly. The shaft extends distally from the body. The blade is disposed at the distal end of the shaft. The acoustic assembly comprises an acoustic waveguide coupled with the blade, a piezoelectric transducer element, a fastener, and a coupling member. The transducer element defines an inner diameter surface and an outer diameter surface. The fastener is configured to secure the transducer element relative to the waveguide. The coupling member is configured to provide electrical continuity between the fastener and the inner diameter surface of the transducer element. The outer diameter surface of the transducer element includes an annular recess. Another coupling member is configured to provide electrical continuity between the annular recess of the piezoelectric transducer element and a power source while permitting the piezoelectric transducer element to rotate relative to the body.

摘要： The design of high-power RF amplifiers, specifically the design of the output transformer, is complicated by the relatively low voltage provided by battery packs that are practical for handheld devices meant for possibly delicate uses. Provided is an RF amplifier with one or more taps on the primary coil, wherein each tap is controlled by a half bridge driver. The output transformer primary winding may be driven between any two half bridge drivers, with the number of turns between the half bridge drivers and the fixed output winding determining the overall turns ration for the transformer.

摘要： Various embodiments are directed to an electrosurgical systems and methods for providing an electrosurgical signal to a patient. An electrosurgical signal defining a plurality of pulses may be provided to first and second electrodes. A first reading may be received indicating an impedance between the first and second electrodes taken at a first point of a first pulse of the electrosurgical signal. A second reading may indicate the impedance a first point of a second pulse of the electrosurgical signal, where the first point of the first pulse and the first point of the second pulse are at equivalent positions within the first and second pulses. Based on a comparison of the first reading and the second reading, a short circuit may be determined and a signal indicating the short circuit may be generated.
