Ultrasonic energy can be applied to surgical instruments for cutting,
dissecting, and coagulating vessels and/or tissue. This book presents the use of
ultrasound energy as it is used in UltraCision products, for use in surgery on
many parts of the body.
Principles of UltraCision technology: The instruments
are attached to a hand piece, which is connected to a generator. The ultrasonic
system is situated inside the hand piece and transforms the electric energy into
mechanical movement, producing in this way longitudinal vibrations of the blades
at approx. 55 kHz per second. The movement of the blades causes collagen
molecules to vibrate inside the tissues, thus forming a coagulum upon their
denaturation. This method is especially useful in parenchymatous organs, where
dissection can be performed cleanly and with little or no bleeding.
Among the applications of UltraCision are:
