Vessel sealing system is an advancement in electrosurgery which transcends the limitation of general principles of electrosurgery. The vessel sealer facilities not only the coagulation of large chunks of tissues (which is not possible in standard cauteries) but it actually seals the vessels in one stroke.
The sealing is reliable, fast and avoids suturing in complicated areas thereby reducing the surgery time and complications. Have a great application in laproscopy, onco surgeries, supra major and critical cases.
