Yes, the geko® device is safe to use in the presence of operating electro-surgery equipment. Electro-surgery equipment uses electrical currents to cut or cauterize tissues. These currents result in intense magnetic and electrical fields which can interfere with electronic devices, including some neuromuscular stimulators. In the past some neuromuscular stimulators affected by electro-surgery malfunctioned and caused burns to patients, resulting in caution being exercised by the industry and regulators. The geko® device has been designed and manufactured to be immune to the magnetic and electrical effects generated by electro- surgery equipment, making them safe to use in operating theatres where electro-surgery is being used.
