  • Patent number: 10238385
    Abstract: A surgical instrument system is disclosed. The surgical instrument system comprises a proximal end, a distal end, a first jaw, and a second jaw. The first jaw is movable relative to the second jaw to capture tissue. The surgical instrument system further comprises a sensor system configured to sense the impedance of the tissue at a plurality of discrete locations, a staple cartridge comprising staple cavities, staples removably stored in the staple cavities, an anvil, a firing system configured to move the staples toward the anvil, an electric motor configured to move the firing system toward the distal end during a firing stroke, and a control system. The control system is configured to evaluate the impedance of the tissue at the discrete locations and control the power applied to the electric motor during the firing stroke as the firing system moves relative to the discrete locations.

  • Patent number: 10201382
    Abstract: A surgical generator is disclosed including an ultrasonic generator module to provide at an ultrasonic drive signal for driving an ultrasonic surgical device and an electrosurgical generator module to provice an electrosurgical drive signal for driving an electrosurgical device. At least one of providing the ultrasonic drive signal or providing the electrosurgical drive signal includes recalling a waveform sample from a look-up table (LUT), modifying the waveform sample to generate a modified waveform based on voltage and current feedback information to pre-distort the waveform sample on a dynamic ongoing basis, indexing each stored voltage and current feedback data pair based on a corresponding LUT sample that was output when the voltage and current feedback data pair was acquired, synchronizing the LUT sample and the voltage and current feedback data pair to correct timing and stability of the pre-distorted waveform sample, and providing the modified waveform to an output stage.

  • Patent number: 10022568
    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.

  • Publication number: 20180064961
    Abstract: In one general aspect, various embodiments are directed to a surgical instrument that can supply mechanical energy and electrical energy to an end effector of the surgical instrument. The surgical instrument may be operated in a first operating mode in which a transducer of the surgical instrument produces mechanical energy, or vibrations, that are transmitted to the end effector and a second operating mode in which electrical energy, or current, can flow through the end effector to perform electrosurgery. In another general aspect, the surgical instrument may comprise a clamp, or jaw, which can be moved into a closed position to hold tissue against a waveguide, or blade, of the end effector. In the second operating mode of the surgical instrument, current can flow from a power source, through the waveguide, and return to the power source through a path comprising the jaw.
