Beschreibung
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:esophageal surgeryreflex surgerygastrectomycolorectal surgery for Crohn's disease, diverticulitis, and cancerlaparoscopic cholecystectomy - hepatic resectionpancreatic surgeryadrenalectomythyroid surgeryhysterectomy and other gynecologic surgeryand much more!For the general surgeon becoming acquainted with this highly effective new surgical tool, this book represents an ideal introduction, including a step-by-step guide to operative sequences, and tips provided by those who have already gained experience in the modality.
