IMPROVED ULTRASONIC SURGICAL TOOL

摘要

The shaped output is for use with an ultrasonic surgical tool vibratable in torsional mode. The output has a generally cylindrical first waveguide (1 ) with, at a distal end a second waveguide extension member (3) of reduced d iameter. The second waveguide (3) is curved in one plane from the axis of th e first waveguide. It has at least two blade faces (4) extending radially ou twardly from its distal end.
