Abstract

Purpose: Vessel sealing capabilities and the peripheral energy spread associated with currently available energy based surgical instruments were evaluated. Materials and Methods: Four groups of energy based surgical instruments were established for evaluation, including the ACE, LCS-C5 (Ethicon, Cincinnati, Ohio), LigaSure V and the prototype Trissector. In vivo vessel diameter under physiological conditions, bursting pressures and seal failure were recorded and analyzed for arteries and veins separately. After burst testing the vessels were fixed and evaluated histopathologically for peripheral energy damage. ANOVA was used to determine differences between groups. Results: The LigaSure V sealed arteries and veins with an average burst pressure of 536 and 386 mm Hg, respectively. The Harmonic ACE sealed arteries and veins with an average burst pressure of 436 and 160 mm Hg, respectively. The Harmonic LCS-C5 sealed arteries and veins with an average burst pressure of 363 and 215 mm Hg, respectively. The Trissector sealed arteries and veins with an average burst pressure of 328 and 237 mm Hg, respectively. For arteries the ACE, LCS-C5, Trissector and LigaSure V measured a full-thickness peripheral energy spread of 0.6, 0.3, 8.0 and 4.5 mm, respectively (p
