Abstract
We have developed an ultrasonic scalpel for laparoscopic use using the porcine cholecystectomy model. Based on experimentation with various blades, the hook-spatula blade appears to offer the best mix of coagulation and cutting. The advantages of this device are that it does not make smoke, causes minimal tissue injury, is safe to the surgeon and patient, and facilitates dissection. We believe it has the potential to become the preferred energy form for therapeutic laparoscopic surgery.
