What is the difference between bipolar and monopolar Forceps?
With Monopolar Forceps , the active electrode is in the surgical site. The return electrode is elsewhere on the patient’s body.
The current passes through the patient as it completes the circuit from the active electrode to the return electrode.
With Bipolar Forceps , both the active electrode and return electrode functions are performed at the site of surgery.
The two tines of the forceps perform the active and return electrode functions. Only the tissue grasped is included in the electrical circuit.
Because the return function is performed by one tine of the forceps, no patient return electrode is needed.
