Electrosurgery is the cutting and coagulation of body tissue using high frequency current. The flow of current is resisted by body tissue and the localised increase in temperature causes thermal destruction of tissue which is medically useful.
An electrosurgical unit generates high frequency current which is delivered through a cable to the operating site via an active electrode / Forcep electrosurgical Instrument. A return electrode or grounding pad is also required. In bipolar surgery the current passes from the active electrode to the return electrode in the immediate vicinity of the tissue site. In monopolar surgery the current travels from the active electrode, through the body to a grounding pad and returns to the generator (to complete the circuit).
Bipolar and monopolar forceps are available in different styles and lengths according to the procedure performed and the access required.
