Argon-Enhanced Electrosurgery
Argon Flow
Argon-enhanced electrosurgery incorporates a stream of argon gas to improve the surgical effectiveness of the electrosurgical current.
Properties of Argon Gas
Argon gas is inert and noncombustible, making it a safe medium through which to pass electrosurgical current. Electrosurgical current easily ionizes argon gas, making it more conductive than air. This highly conductive stream of ionized gas provides the electrical current an efficient pathway.
- Inert
- Noncombustible
- Easily ionized by RF energy
- Creates bridge between electrode and tissue
- Heavier than air
- Displaces nitrogen and oxygen
Argon-Enhanced Coagulation and Cut
There are many advantages to argon-enhanced electrosurgical cutting and coagulation.
- Decreased smoke, odor
- Noncontact in coagulation mode
- Decreased blood loss, rebleeding
- Decreased tissue damage
- Flexible eschar
