Endotracheal tube damage during head and neck surgeries as a result of Harmonic Scalpel
Using the dynamic tissue effects of mechanical energy, ultrasonic blades, and shears, tissue effects from ultrasonic energy using the Harmonic Scalpel
(EES, Cincinnati, OH) are actuated by a titanium blade of variable excursion that vibrates nearly 55,500 Hz/second from an in-line piezoelectric crystal housed in the hand piece of the device.
The surgeons performed laparoscopic unilateral oophorectomy on each patient, using a harmonic scalpel
to quickly retrieve the ovary and to prevent thermal damage.
Another alternative to diathermy is to use a harmonic scalpel
which uses ultrasound waves to cut and coagulate tissue.

, and the argon beam coagulator.
Hemorrhoidectomy performed with a Ligasure hemostatic device causes less postoperative pain and takes less time to do than hemorrhoidectomy with the Harmonic Scalpel
, reported Shek Yuen Kwok, M.
Seven days after patients with a total of three grade 3 or 4 hemorrhoids underwent a hemorrhoidectomy in a single-blind, randomized trial, the median postoperative pain score (assessed pain with a visual analog score) for the 24 patients in the Ligasure group was significantly lower than that for 23 patients in the Harmonic Scalpel
