SYSTEM HAVING MULTIPLE PNEUMATICALLY SEALED TROCARS

摘要

A valve assembly and method are provided for selectively controlling a flow of pressurized fluid from a fluid source to trocar assemblies. The valve assembly includes a first coupling configured and adapted to couple to a primary trocar assembly for directing pressurized fluid thereto, a second coupling configured and adapted to couple to a secondary trocar assembly for directing pressurized fluid thereto, a third coupling configured and adapted to couple to a source of pressurized fluid for directing pressurized fluid from the source to the first and second couplings; and at least one valve member adapted and configured to be operable in at least first and second operating positions, wherein (i) the first operating position directs pressurized fluid from the source to a coupled primary trocar assembly while preventing pressurized fluid from the source from flowing to at least a coupled secondary trocar assembly, and (ii) the second operating position directs pressurized fluid from the source to the coupled primary trocar assembly and to at least the coupled secondary trocar assembly.
