A mains electricity (AC-powered) device assembly designed to provide operating room (OR) staff with a single point of management to operate electromechanical/electronic medical devices of different makes during surgery. It is a computer-based integrated hardware/software application that typically consists of a base unit (outside the sterile field or the OR) to which all device cabling is connected, and software that runs on an off-the-shelf computer with a touchscreen (in the OR). The system is intended to manipulate devices such as OR lights, OR tables, cameras, video endoscope images, and monitors; it may also be used to manage patient data from these devices.
