LigaSure technology is considered as the standard in vessel sealing. In fact, it has been used in more than 19 million procedures worldwide.
It delivers a combination of pressure and energy to create a consistent seal with each application. It is designed to deliver high current and very low voltage to tissue. It monitors tissue impedance between the jaws of the instrument and continuously adjusts the delivery of energy.
It seals vessels in 1 second to 4 seconds in most surgical situations when used with next generation advanced energy platforms, and provides permanent vessel fusion up to and including 7mm in diameter without dissection nor isolation. It also seals lymphatics and tissue bundles.
The electrosurgical generator is responsible for the detection of the characteristics of the tissue closed between the instrument jaws so it can deliver the exact amount of energy needed to seal it permanently. It also includes several types of instruments that seal and, in some cases, divide the tissue when necessary.
It is generally used in open and minimally invasive surgery including anti-reflux, colorectal, gynecologic, urologic, and endocrine surgical procedures.
How it works?
This technique is different from the conventional coagulation methods that achieve vessel sealing by tissue carbonization. It involves clamping on tissue which compresses the vessel walls. The current then begins to flow through tissue, thereby, creating heat. Native tissue proteins denature while water turns to vapor and escapes. LigaSure technology fuses the internal walls of the vessels resulting in complete luminal occlusion.
Operating performance is significantly amplified by this technology as it has been found to have the highest burst pressure and fastest sealing time. Hence, it reduces more procedure time, patient length of stay, and blood loss compared to sutures and clips. It also reduces the cost of disposable surgical supplies as it does not require multiple reloadable cartridges.
What is amazing is it provides a natural seal containing only the patient’s own collagen. It also offers minimal sticking, tissue charring, and thermal spread, unlike standard bipolar, and monopolar electrosurgery.
