Abstract:
1. A surgical tool capable of transmitting torsional ultrasonic vibrations, said surgical tool comprising a longitudinally extending guide defining a longitudinal axis of said tool, a first jaw member at a distal end thereof having an operating surface with a profile comprising an angled cutting element and a coagulating element, a longitudinally extending carrier rotatable about said guide, a second jaw member mounted pivotably to a distal end of said carrier, said second jaw member having a surface which has complementary shape to that of the operating surface of the first jaw member, and outer shroud including operating means for actuating said second jaw member wherein rotation of said carrier acts on the operating means to cause pivoting of said second jaw member into and out of operative relationship with said first jaw member, wherein the second jaw member pivots about a first axis substantially simultaneously with rotation of the first axis about a second axis substantially orthogonal to the first axis.
