COUPLING DEVICES FOR TUBE SETS USED WITH SURGICAL GAS DELIVERY SYSTEMS

摘要

A coupling system is disclosed for connecting a tube set to a trocar that includes a multi-lumen trocar having a housing that has a connector extending outwardly from the housing, the connector having a plurality of coaxial flow passages defined therein by a plurality of concentric annular walls, a multi-lumen tube set including a plurality of tubes arranged in a parallel relationship, a coupling including a generally cylindrical body having a first end portion adapted and configured to selectively mate with the coaxial flow passages of the connector of the trocar and a second end portion adapted and configured for attachment to the parallel tubes of the tube set, and a latch assembly operatively associated with the cylindrical body of the coupling for selectively engaging the connector of the trocar housing when the coupling mates with the connector.
