capacitive coupling

Electronics
The intentional or fortuitous transfer of energy within an electrical network by capacitance between circuit nodes.

Surgery
A potential endoscopic electrosurgical hazard, which occurs when electrical current is transferred from one conductor —e.g., an active electrode surrounded by insulation—into adjacent conductive materials—e.g., a trocar or tissue. The risk of tissue damage can be reduced by using low-power, low-voltage settings with intermittent rather than prolonged bursts, and by not operating near metal or conductive objects in the operative field.

The Laparoscopic Mode offers optimal safety by limiting output voltage through microprocessor controlled circuitry and minimizes the potentially harmful effects of capacitative coupling.
Many find the concept of capacitative coupling difficult to understand--and this makes prevention of related injuries more difficult.
The Harmonic Scalpel offers several advantages over monopolar electrosurgery for cutting, such as decreased smoke formation and avoidance of complications such as insulation failure, direct coupling, and capacitative coupling.
