  • Publication number: 20150351755
    Abstract: A process and system are disclosed for downloading sensor data, stored in a memory device of a surgical cutting and fastening instrument, to an external or remote computer device. The process may involve storing data from one or more sensors of a surgical cutting and fastening instrument in a memory device of a control unit of the surgical cutting and fastening instrument during a surgical procedure involving the surgical cutting and fastening instrument. Next, after the surgical procedure, a data link between the control unit and the remote computer device is established. Then, the sensor data can be downloaded from the control unit to the remote computer device.

  • Publication number: 20150340586
    Abstract: A method for controlling a waveform shape of a motional branch current in an ultrasonic transducer of a surgical device. The method may comprise generating a transducer drive signal by selectively recalling, using a direct digital synthesis (DDS) algorithm, drive signal waveform samples stored in a look-up table (LUT), generating samples of current and voltage of the transducer drive signal when the transducer drive signal is communicated to the surgical device, determining samples of the motional branch current based on the current and voltage samples, a static capacitance of the ultrasonic transducer and a frequency of the transducer drive signal, comparing each sample of the motional branch current to a respective target sample of a target waveform to determine an error amplitude, and modifying the drive signal waveform samples stored in the LUT such that an amplitude error between subsequent samples of the motional branch current and respective target samples is reduced.

  • Publication number: 20150328484
    Abstract: Various embodiments are directed to a method of driving an end effector coupled to an ultrasonic drive system of a surgical instrument. In accordance with the method, a generator is configured to generate at least one time varying electrical signal having a resonant frequency, monitor the resonant frequency of the at least one electrical signal, calculate a frequency slope between frequency data points of the time varying electrical signal, where the frequency slope is the change in resonant frequency over time, compare the frequency slope to a threshold frequency slope, and trigger a first response of the generator when the frequency slope crosses the threshold frequency slope.
