摘要： A method for calculating the capacitance of a transducer (C0) without knowing the exact resonance frequency of a transducer/blade combination is achieved by sweeping across a broad frequency range which contains resonant and non-resonant frequencies where C0 can be measured. A pre-defined frequency range is set independently of the resonance frequency of a specific transducer/blade combination. C0 of the transducer/blade is measured at several different frequencies within the pre-defined frequency range to ensure that invalid C0 measurements are disregarded, and the temperature of the transducer is calculated based on valid C0 measurements. The determined transducer temperature, based on C0 measurements, can be used to optimize performance and/or provide a safety shutdown mechanism for the generator.

摘要： A temperature or impedance sensing device monitors the tissue temperature or impedance at the end-effector of a therapeutic ultrasonic cutting and coagulating instrument as the tissue is being heated with ultrasonic vibrations from the end-effector. One or more sensors are located at the end-effector, preferably on a clamping member. The signals from the sensors provide feedback to control circuitry and a device for selecting a function of the instrument for either cutting mode or coagulating mode.

摘要： A surgical instrument includes a transducer configured to produce vibrations at a predetermined frequency. The transducer is configured to produce vibrations at a predetermined frequency. An ultrasonic blade extends along the longitudinal axis and is coupled to the transducer. The ultrasonic blade includes a body having a proximal end and a distal end. The distal end is movable relative to the longitudinal axis by the vibrations produced by the transducer. The body includes a treatment region that extends from the proximal end to the distal end. The body includes surface coatings to prevent the formation of a thin layer of fluid on the body which may be atomized thus creating a mist. The body may also include a bore configured to emit a spray which will also prevent the formation of thin layer of fluid on the body.

摘要： Various example embodiments described herein are directed to articulating surgical instruments for treating tissue comprising an end effector and a shaft extending proximally from the end effector along a longitudinal axis. In certain embodiments, the shaft comprises a plurality of transverse spacer members as well as first and second rotatable members extending through at least a portion of the plurality of transverse spacer members. The first and second rotatable members may both be biased away from the longitudinal axis such that their respective directions of bias vary with rotation of the first rotatable member. When the respective directions of bias of the first and second rotatable members oppose one another, the shaft may be substantially straight. When the respective directions of bias of the first and second rotatable members are aligned with one another, the shaft may articulate away from the longitudinal axis in the direction of the alignment.

摘要： Various embodiments described herein are directed to ultrasonic blades. For example, an ultrasonic blade may comprise a proximally positioned straight section extending along a longitudinal axis and a distally positioned curved section coupled to the straight section and curved away from the longitudinal axis. The curved section may define a radius of curvature and subtend a first angle. A point of tangency between the curved section and the straight section may be positioned at either a node of the ultrasonic blade or an anti-node of the ultrasonic blade.
