When a surgeon conducts a laparoscopic surgery, a need may exist to ligate the blood vessels or tissues with the aim to reduce the blood supply to a certain body part. For this purpose, vessel sealing systems are employed. A multiplicity exists in the available options for the sealing of vessels during surgery. One of these is the LigaSure vessel sealing system.


What is LigaSure vessel sealing system?

LigaSure vessel sealing system is a vessel welding device that works on the principle of electrothermal heat generation and transfer to the target site. This way, a vessel can be sealed with minimum time and maximum efficiency.

Characteristics of LigaSure vessel sealing system

The LigaSure vessel sealing system has the following characteristics:

ParametersLigaSure vessel sealing device (LVSS)
Working principle The LigaSure device works on the principle of electrosurgery i.e. it has the potential to convert the electric current provided to it into heat which further melts and seals the vessel tissue.
Operation time (min)With the use of LigaSure device, the operation of the surgery is lesser in relation to that with the use of harmonic scalpel. The average time of surgery with LigaSure device is 187.6 min.
Visibility During its working, the LigaSure system generates heat to seal the tissue. This cooking of tissue can generate smoke which can thus reduce the visibility near the area where the surgery is being done.
Burst pressure (mm Hg)With LVSS employment, the burst pressure remains moderate i.e. between 591 to 836 mm Hg.
Thermal spread The lateral thermal spread with the use of LigaSure device does not exceed 2 mm.
Cost of the surgery (e.g. thyroidectomy)For thyroidectomy, the surgical procedure can be conducted with an approximate budget of $2,300.
Post-operative levels of calcium (mg/dl)The post-operative calcium levels after the surgery with LVSS are, on average, 8.2 mg/dl.



Types of LigaSure devices based on their jaw shape

LigaSure devices are not restricted to a single design. Rather, several tip modifications are available in the market which is given as follows:

L-hook LigaSure device is a preferred choice for conducting gastrotomy (i.e. surgical incision in the stomach) and enterotomy (i.e. surgical incision of the intestines).
