What is the Ligasure characterized by in terms of current and voltage?

The Ligasure device is designed to achieve tissue fusion and hemostasis through the application of a controlled amount of electrical energy. It specifically utilizes high current and low voltage to effectively seal the tissue.

In this mode of operation, high current helps to generate sufficient heat in the tissue, facilitating the denaturation of collagen and elastin, which are key proteins that contribute to the mechanical strength of tissues. Meanwhile, the low voltage aspect is crucial as it minimizes the risk of thermal spread to surrounding tissues while still achieving the necessary conditions for effective tissue sealing.

Therefore, the characteristics of high current and low voltage play a vital role in the efficiency and safety of the Ligasure device in surgical applications, ensuring that the targeted tissue is fused correctly without excessive damage to adjacent areas.
