During cutting and fulguration, the current sparks from the active electrode to the tissue with no contact, while coagulation and desiccation occur when the active electrode contacts the tissue. Coaptive coagulation can occur with both monopolar and bipolar forceps; this is where tissue is compressed between the jaws of the instrument, thus coapting the blood vessel to prevent the ‘sink effect’ (where heat is carried away by the flow of blood) and to achieve haemostatic sealing. In monopolar coaptive coagulation, it is recommended to use the ‘cut’ rather than the ‘coagulation’ waveform because it results in a complete homogenous seal with reduced electrosurgical risks caused by the associated low voltage.
