Multi-modal five lumen gas circulation system for use in endoscopic surgical procedures

A system for performing an endoscopic surgical procedure in a surgical cavity, comprising:

• a) a multi-modal gas delivery device including a housing enclosing internally a primary gas circulation pump, a secondary gas circulation pump and an insufflation subunit;
• and
• b) an interface plate adapted and configured to engage with the multi-modal gas delivery device and including opposed front and rear surfaces, wherein five connectors are located on the front surface of the interface plate and five filter seats are located on the rear surface of the interface plate, and wherein each of the five filter seats on the rear surface of the interface plate has a port formed therein that communicates with an oppositely adjacent one of the five connectors on the front surface of the interface plate to form a connection, wherein each of the five connections corresponds to one of the following five lumens:
• i) an insufflation and sensing lumen for delivering insufflation gas from the insufflation subunit to the surgical cavity and for facilitating sensing of surgical cavity pressure;
• ii) a gas delivery lumen for delivering pressurized gas from the primary gas circulation pump to a gas sealed access device;
• iii) a gas return lumen for returning gas used to generate a gaseous seal within the gas sealed access device back to the primary gas circulation pump;
• iv) a smoke evacuation lumen for removing smoke filled gas from the surgical cavity by way of the secondary gas circulation pump;
• and
• v) a recirculation supply lumen for returning filtered gas back to the surgical cavity from the secondary gas circulation pump.
