Core Tip
Core Tip: The present study showed that the tissue pad of the Harmonic® 1100 (H-1100) ultrasonic scalpel, with improved heat control technology, was preserved even in a hepatectomy model, which is a severe condition for ultrasonic devices. It can be inferred that by using the H-1100 scalpel, even surgeons-in-training inexperienced in handling ultrasonic devices do not need to worry about device issues related to tissue pad degradation. Furthermore, use of the H-1100 scalpel may eventually reduce hospital costs.
