Cameron Miller 80-1983 ESU
The Cameron Miller 80-1983 electrosurgical generator has many unique features which allow its use in a variety of modes.
Solid state circuitry with isolated R.F. outputs reduces the risk of alternate path burns.

Monopolar and bipolar circuitry
Electrosurgical generators complete electrical circuits by using either monopolar or bipolar devices. The difference between the 2 relates to the location of the active and the neutral electrodes. In endoscopy, the active electrode is a through-the-scope endoscopic accessory, such as a polypectomy snare and thermal ablation device. In a monopolar circuit, current passes from the active electrode into the target tissue, then courses through the patient in the least resistant direct path to a neutral electrode, then back to the ESU. Neutral electrodes are sometimes referred to as return electrodes and inaccurately as grounding pads. Older ground referenced ESUs, which required the current to pass into the ground rather than back to the ESU, are now obsolete. Examples of endoscopic interventions delivered using monopolar circuitry include snare polypectomy, sphincterotomy, hot forceps biopsies, argon plasma coagulation (APC), and endoscopic submucosal dissection by using needle-knives and similar accessories.
In bipolar circuits, the device contains both the active and neutral electrodes in close proximity. Applied current passes from the active electrodes into the target tissue, then immediately returns to the neutral electrodes on the same device, and then back to the ESU. Because bipolar circuits are completed locally, no separate return electrode (grounding pad) is required. Endoscopic interventions using bipolar circuits have been used for tissue coagulation, such as contact thermal hemostasis with bipolar probes and radiofrequency ablation of Barrett’s esophagus.
