Popis knihy

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.
