Cavitron Ultrasonic Surgical Aspirator Dissectron Integra NeuroSciences

The principle of ultrasonic dissection is a cavitational effect which occurs at the tip of the vibrating rod of the device. The handpiece delivers ultrasonic vibration and provides simultaneous aspiration and irrigation (A-1). The ultrasonic probe divides parenchymal cells (because of their high water content) by the cavitational effect with less injury to structures with a high content of fibrous tissue, e. g., bile ducts and blood vessels (A-2). Once skeletonized by the probe, these elements are then clipped, ligated or coagulated as with the other techniques. Additional electrocoagulation functions are optionally available. The ultrasonic and high frequency currents can be activated simultaneously to divide and coagulate vessels, ducts and nerves.
