ligasure usually produces very low heat while harmonic doesn't reach even that level...
as compared to electrosurgical cautery, both are better.
in harmonic scalpel, they create negative atmospheric pressure locally by 55k hz ultrasonic frequency, this lowers down the boiling temperature of water and hence it coagulates at lower temperature

Harmonic Scalpel better than Ligasure. This screen facts about thermal damage on ınfrared camera. Harmonic Scalpel thermal damage lower than Ligasure. It's about <1.2mm. But above at all; you need know what's the thermal damage.
Note: Left: Harmonic Right: Ligasure
