Key Points
A basic understanding of electrosurgical devices is required to allow for appropriate use and prevention of morbidity relating to their use.
Three different types of coupling injuries can occur with monopolar devices: direct, indirect, and capacitive coupling.
Indirect coupling results from defects in the insulating coating of the electrode (instrument), often leads to large current densities concentrated in small areas, and can result in high‐morbidity injuries.
Tissue fusion technology or vessel sealant devices measure tissue impedance and deliver the appropriate amount of energy to achieve a safe seal. They are approved for sealing vessels up to 7 mm in diameter.
