How AEM® Burn Protection Works

Encision’s Shielded AEM® Instruments and Monitors eliminate the chance of stray energy burns to patients during laparoscopy, by electrically shielding and monitoring the AEM® Instrument inside the patient’s body.

Every AEM instrument has a protective shield that is actively monitored throughout a procedure. This protective shield eliminates the risk of capacitive coupling to the patient by draining the energy away from the patient, back to the AEM Monitor. If an insulation failure occurs, the AEM System actively drains the electrosurgical energy away from the patient through this protective shield. In addition the AEM Monitor immediately shuts down the instrument power, similar to a circuit breaker (GFCI) in the electrical wiring of a house.

How AEM works

In every AEM instrument, the active electrode is surrounded by the primary insulation layer. The primary insulation layer withstands the high voltages of electrosurgery, ensuring effective use of the active electrode. The protective shield is a conductive tube that surrounds the primary insulation layer and active electrode. The shield conducts stray energy back to the generator, ensuring there is no chance of a stray energy burn to the patient. The outer insulation provides an additional layer of insulation for all AEM instruments.
