Case Study of Electromagnetic Interference in Surgery Environment

In this paper, a case of electromagnetic interference (EMI) in medical display systems is reported. It concerns the nearby use of an electrosurgical knife disturbing video-monitors, interconnected by Ready-Made Connecting Devices (RMCD), in a surgery room. Based on full wave simulations, three parameters of these RMCD in a medical display installation, including the total length, location of connecting and the number of GND reference - wires, are identified. The simulation results demonstrate that these parameters can not only lead to EMI but are also influencing the characteristics of such EMI.
