Patent
Ultrasonic surgical instruments
TL;DR: In this paper, a transducer and an end effector are configured to provide vibrations along a longitudinal axis at a predetermined frequency and may comprise a piezoelectric stack positioned along the longitudinal axis.
Patent
Apparatus and method for alerting generator functions in an ultrasonic surgical system
TL;DR: In this article, an ultrasonic hand piece having a end-effector, a console having a digital signal processor (DSP) for controlling the hand piece, and a memory disposed in the end effector was presented.
Patent
Ultrasonic device for cutting and coagulating with stepped output
James R. Giordano,Robert J. Beetel,Eitan T. Wiener,Jeffrey D. Messerly,Brian F Dinardo,Daniel J. Abbott +5 more
TL;DR: In this article, a generator coupled to an ultrasonic transducer is used to generate a first ultrasonic drive signal for a first period, followed by a second drive signal subsequent to the first period.
Patent
Electrosurgery generator for ultrasonic surgical instruments
TL;DR: In this article, a surgical instrument can 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, or current, can flow through the end-effector to perform electrosurgery.
