The surgeon prefers the argon beam coagulator for dissection in his liver procedures,because the liver bleeds easily,and traditional monopolar electrosurgery often causes more bleeding than it stops.What is the application characteristic of the argon beam coagulator that enhances liver tissue hemostasis?

An argon-enhanced ESU device combines argon gas with electrosurgical energy to improve the effectiveness of the electrosurgical current.Because argon gas is heavier than air,inert,and noncombustible,it creates an efficient pathway for electrosurgical energy to travel from electrode to target tissue.The flow of argon gas also clears the surgical site of blood and fluids,allowing for greater visibility of the bleeding site or target area,and disperses oxygen,decreasing the chance of combustion,and formation of surgical smoke.Benefits of argon-enhanced electrosurgery include: rapid coagulation of diffuse bleeding site with reduced blood loss,reduced risk of rebleeding,noncontact tissue coagulation,reduced depth of penetration by electrical energy,and less adjacent tissue damage.
