Ultrasonic surgical instruments

摘要

In one general aspect, various embodiments are directed to an ultrasonic surgical instrument that comprises a transducer configured to produce vibrations along a longitudinal axis at a predetermined frequency. In various embodiments, an ultrasonic blade extends along the longitudinal axis and is coupled to the transducer. In various embodiments, the ultrasonic blade includes a body having a proximal end and a distal end, wherein the distal end is movable relative to the longitudinal axis by the vibrations produced by the transducer.

主权项

1. An ultrasonic surgical instrument, comprising:
a handle comprising a pivoting handle portion; an end effector configured to treat tissue, wherein said end effector comprises a clamp arm comprising a tissue pad, and wherein said pivoting handle portion is configured to move said clamp arm between an open position and a closed position; a waveguide extending to said end effector; a battery; and a vibration generating system selectively operable in a plurality of energizing operating states, wherein said plurality of energizing operating states consists of:
a first operating state in which a first power is supplied to said end effector; anda second operating state in which a second power is supplied to said end effector, wherein said first power is different than said second power; and wherein said vibration generating system comprises:
a transducer selectively attachable to said handle; anda switch configured to operably switch said vibration generating system between said first operating state and said second operating state, wherein said switch is positioned on said handle.
