Abstract
Summary Minimally invasive interventions require a multitude of technical devices, like gas-insufflators, cameras, light-sources, high-frequency and others. The devices available today represent stand-alone ‘function-insulas’ from the view-point of systems technique. They have to be placed in the operating theatre and set up right before each specific intervention. From each single devices supplies, cables and hoses lead to the body of the patient. They have to be connected on both sides, within the sterile and the non-sterile field. One of the major drawbacks lies in the lack of direct control of the devices by the surgeon and the confusing display of parameters and the technical status. On this background the systematic revision of the current endo-surgical work-place appears to be a major requirement for further technical and surgical progress in endoscopic surgery. In close cooperation between surgeons and engineers a systems work-place for minimally invasive surgery, OREST, has been developed and clinically tested. It integrates all devices into a mobile cabinet. The single devices are connected to a central computer and can be remote-controlled directly by the surgeon from the table. A special display continuously informs about the system status. The lines and cables are guided into the sterile field by means of a swivel arm from one side of the patient. Four multi-plugs are used to connect all lines at a central terminal within the sterile area. Clinical application of the first prototype OREST I started in 1993.
