What device is used in robotic da Vinci thyroidectomy to simultaneously dissect and cauterize?

The harmonic scalpel is specifically designed for surgical procedures that require both dissection and coagulation of tissue. This device employs ultrasonic energy to generate vibrations that cut through tissue while simultaneously causing coagulation through the heat produced by the ultrasonic waves. This unique mechanism allows for precise dissection of delicate structures, such as in a thyroidectomy, while effectively controlling bleeding by cauterizing the tissue as it cuts. The harmonic scalpel is particularly advantageous in robotic surgeries, including da Vinci systems, due to its ability to minimize thermal spread and collateral damage to surrounding tissues.

In contrast, other devices such as an energy shaver, electrocautery unit, and laser scalpel each have specific functions that might not provide the same level of simultaneous dissection and cauterization tailored for the nuances of robotic thyroid surgery. The energy shaver is typically used for tissue removal but does not uniquely emphasize simultaneous dissection and cauterization in the same manner as the harmonic scalpel. Electrocautery relies on electric current to cut and coagulate but may not be as delicate or precise as the ultrasonic principle used in a harmonic scalpel. Meanwhile, a laser scalpel primarily focuses on cutting tissue using laser energy and is less versatile for simultaneous cauterization compared to
