Abstract
The ultrasonic surgical tool has an elongate waveguide operatively connected or connectable at a proximal end to a source of ultrasonic vibrations. At a distal end, an operative element comprises a radially-extending ridge defined between a substantially parallel pair of grooves extending longitudinally of the waveguide. The operative element is curved in a plane transverse to that of the ridge. This arrangement is ergonomically superior and allows a surgeon to work for longer and with improved control. It also allows a clear visualization of the operative elements of the tool and the target tissue.
