electrosurgery
[-sur′jərē]
Etymology: Gk, elektron + cheiourgos, surgeon
surgery performed with various electric instruments that operate on high-frequency electric current. Kinds of electrosurgery include electrocoagulation, electrodesiccation.
electrosurgery,
n the use of electrically generated energy from high-frequency alternating currents to cut or alter tissue within definite limits.
electrosurgery
the use of high-frequency alternating current to remove, incise or destroy tissue. This is accomplished by converting the electrical energy into heat through tissue resistance to the passage of the electrical current. Called also surgical diathermy.
Two types of current are utilized in electrosurgery, damped and undamped; a damped current destroys and coagulates tissue and stops bleeding, and undamped current destroys minimal tissue and incises tissue. Basically, there are four types of electrosurgical techniques: electrodesiccation, electrofulguration, electrocoagulation and electrosection.
