Ultrasonic Energy for Cutting, Coagulating, and Dissecting [EPUB ebook] 

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 Ultra Cision products, for use in surgery on many parts of the body.Principles of Ultra Cision 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 k Hz 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 Ultra Cision 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.
