Ultrasonic surgical systems deliver vibrational energy to ablate tissue and affect hemostasis. Unlike radiofrequency (RF) and laser systems that achieve coagulation through thermal welding, ultrasonic energy is not reliant upon heat to seal tissue. The popularity of ultrasonic systems is being driven by several inherent advantages. The absence of smoke, which improves the visual field and eliminates the need for smoke evacuation, improves intraoperative visualization. Further, these instruments combine grasping, cutting and coagulation into one integrated tool set that reduces cost and time consuming, intraoperative instrument exchanges. Patient safety is enhanced as there is an absence of electrical current passing through a patient’s body and lateral tissue damage is therefore minimized. The procedures that benefit most from the inherent advantages of ultrasonic surgical systems are advanced laparoscopic procedures.
Below are illustrated the procedures with the highest growth in the application of ultrasonic surgical systems. Over the 2003-2008 timeframe, each of these demonstrated double-digit growth, with growth in gastric bypass (bariatrics, obesity) and prostatectomy outpacing all others. Over the next five years, these procedures will demonstrate comparable growth.
