Abstract: A dual pump irrigation/aspiration pump system capable of operating in a plurality of different modes suitable for a variety of different endoscopic surgical procedures. The system monitors actual or calculated intra-articular pressure and adjusts flow to maintain surgeon requested pressure at the surgical site while controlling outflow. The irrigation/aspiration pump system has an inflow pump and tubing dedicated to communicating fluid to the surgical work site and an outflow pump and tubing dedicated to removing fluid from the work site at a controlled rate. The system further has different size inflow and outflow pumps and tubing cassettes, means for altering the outflow fluid flow rate to accommodate a surgical tool and a means for declogging the surgical tool in the event of blockage. In a preferred embodiment a pressure control system provides inferred pressure information representative of the pressure at the work site.

Abstract: The present invention allows operating room personnel to easily and expeditiously drape electronic surgical devices, such as video monitors, cameras, lights, and power sources. This invention relates to a disposable, four-sided surgical drape that maintains a protective cover over the equipment. The drape consists of an opaque material on the two side panels and the top panel of the drape. The front panel is preferably formed of a clear, pliable plastic material, with a rectangularly shaped front panel cutout at the top portion of the panel. This front panel cutout and the attached adhesive strip allow surgical personnel to visually access the video monitor and seal the front panel to the monitor. The rear and underside of the cover are open to ensure proper ventilation and easy application.
