Abstract

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.

Claims

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;
