Hybrid Cannula System
The worst case occurs when a metal cannula is held in place by a plastic anchor (hybrid cannula system). The metal cannula still creates a capacitor with the active electrode. However, the plastic abdominal wall anchor prevents the current from dissipating through the abdominal wall. The capacitively coupled current may exit to adjacent tissue on its way to the patient return electrode. This can cause significant injury.
