Monopolar electrosurgical instruments
Monopolar electrosurgical instruments are the most commonly used energy devices. Table 3 summarises the versatile functions of these devices.
| Variables | Electrosurgical effects of monopolar instrumentation | |||
|---|---|---|---|---|
| Cutting | Coagulation | Fulguration | Coaptive coagulation (≤2 mm vessel) | |
| Tissue temperature (°C) | >100 | 60–95 | >200 | 60–95 |
| Tissue effect | Vaporisation | White coagulation | Black coagulation | Vessel sealing |
| Best achieved with (output type) | Cut | Cut | Coagulation | Cut |
| Electrode position | Near contact | Contact | Non contact | Compressing |
| Electrode shape | Needle | Wider | Needle | Jaws of forceps |
