Cutter Having Vibratory Drive Means Patents (Class 606/169)
  • Patent number: 11123127
    Abstract: A thermal surgical instrument having a system to control the delivery of power from an energy source to an active element located on a tip. The system for controlling delivery to the tip may include a control algorithm which uses one or more measurements, such as tip current, SWR, and rapid changes in reflected power, to manage power without affecting cutting efficacy, and in a manner that may be imperceptible by a surgeon. The system may utilize a state machine to determine the current environment in which the tip may be in. Power delivered to the tip may be selectively managed according to a fixed power index or a repeatedly executed power profile.

  • Patent number: 10786275
    Abstract: An ultrasonic tool system with a console (230) and a tip (142) that has a distal end that when vibrated vibrates both longitudinally and torsionally. The console applies a drive signal to the drivers (36) that vibrate the tip that is at a longitudinal mechanical cancelation frequency. Consequently, when the tip is vibrated, at the distal end the longitudinal component of a first resonant mode of the tip cancel out the longitudinal component of the second resonant move of the tip so the distal end of the tip engages in vibrations that substantially torsional and only minimally longitudinal.
