Summary
With US scalpels a new era of laparoscopic surgery has begun. We have given instances of the striking advantages of modern ultrasonic dissectors in general, and of the SonoSurg system in particular. Key aspects are reusability, modularity and multi-functionality. Modularity allows for extension of the basic scalpel e.g. to an aspirator, reusability results in cost effectiveness. Nevertheless, ultrasonically activated devices are not limited to the well-known scalpels and aspirators. New technologies such as the SonoSurg ultrasound trocar and combination instruments are currently under development.
