摘要：
Systems for insufflation and recirculation of insufflation fluid in a surgical procedure include a control unit having a fluid pump, a supply conduit, a return fluid conduit and a pressure-controlled valve. The pressure-controlled valve is in fluid communication with an insufflation gas supply, the supply conduit and the return conduit and is adapted and configured to respond to pressure control signals to adjust position and thereby system flow parameters, to reduce entrainment of air from the surrounding environment, and to increase the concentration of insufflation gas in an operative space, and/or to reduce an overpressure condition in the operative space.
