Ultrasonic Energy for Cutting, Coagulating and Dissecting
As technological advances continue to make surgical procedures more effective and efficient than ever, physicians are faced with the constant challenge of keeping abreast of the latest techniques and equipment. In Ultrasonic Energy for Cutting, Coagulating and Dissecting, an experienced team of surgeons offers a comprehensive guide to a large array of procedures that can be performed with new tools that use ultrasonic energy to cut and dissect issues. The system described here Ultra-Cision-uses a hand piece that transforms electrical energy into mechanical movement, which causes the scalpel blade to vibrate at approximately 55 KHz per second. This movement in turn causes the proteins at the instrument tip to denature a sticky coagulum is formed, resulting in clean dissection and coagulation with little or no bleeding, which makes this type of surgery particularly effective for procedures in the parenchymatous organs. Used in operating rooms world wide in both laparoscopic and open surgical procedures, the surgical techniques described here enable the surgeon to target difficult-to-reach spaces, such as those that are close to vital organs. Ultra Cisionoffers the surgeon increased visibility and lessens the risk of damage to tissues and blood vessels.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 surgery;
reflex surgery;
gastrectomy;
colorectal surgery for Crohn's disease, diverticulitis, and cancer;
laparoscopic cholecystectomy - hepatic resection;
pancreatic surgery;
adrenalectomy;
thyroid surgery;
hysterectomy and other gynecologic surgery;
and 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. -
