摘要

An ultrasonic surgical system has an ultrasonic unit including an instrument operatively connected to an ultrasonic generator, wherein the instrument has an 5 ultrasonic end effector on the distal end of a shaft. The system further includes a positioning unit including a movable arm adapted for releasably holding the instrument, whereby an operator may direct the positioning unit to position the end effector at a surgical site inside a body cavity of a patient for performing a plurality of surgical tasks. The system further includes a control unit 10 operatively connected to the ultrasonic and positioning units, wherein the control unit is programmable with a surgical subroutine for performing the surgical tasks. The system further includes a user interface operatively connected to the control unit for initiating an operative cycle of the surgical subroutine such that the surgical tasks are automatically performed during the 15 operative cycle.
