摘要：

The aim of this experimental study was to compare the disadvantages of a monopolar electric scalpel and an ultrasonically-activated scalpel in a porcine model. Using thermal gradients, the ultrasonically-activated scalpel significantly decreased thermal energy dispersion to surrounding structures and thus decreased the risk of injuries to adjacent tissues and nerves, as opposed to the monopolar electric scalpel. Histological examination of nerves showed that necrosis was significantly less important with the use of the ultrasonically-activated scalpel. This experimental study demonstrated that the ultrasonically-activated scalpel caused less thermal and histological damage than the monopolar electric scalpel.
