A surgical gas delivery system is disclosed that includes a device housing supporting a control unit and a filter interface having a seat for receiving a filter cartridge, the filter cartridge having a filter housing defining an interior reservoir, wherein sensors are coupled to the control unit for sensing a level of liquid within the reservoir of the filter cartridge to prevent contamination of the device, and wherein a set of blocking valves are provided in the device housing for interacting with the filter cartridge when it is received in the filter interface to control flow through suction and pressure lines of the device, and wherein the control unit is adapted to recognize a characteristic of the filter cartridge received in the filter interface.

Filter interface for multimodal surgical gas delivery system

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 for a primary trocar assembly for directing pressurized fluid thereto, a second coupling for a secondary trocar assembly for directing pressurized fluid thereto, a third coupling for a source of pressurized fluid for directing pressurized fluid from the source to the first and second couplings; and at least one valve member to be operable in at least first and second operating positions, the first operating position directing 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 the second operating position directing pressurized fluid from the source to the coupled primary trocar assembly and to at least the coupled secondary trocar assembly.

System having multiple pneumatically sealed trocars

The subject multimodal surgical gas delivery system configured to couple to one or more surgical devices providing access into a patient body cavity includes a computer-controlled control unit configured and adapted to provide at least one of the following modes of operation. A first mode of operation for providing a pressurized insufflation fluid from an insufflation gas source into a surgical device for providing and maintaining sealable access to the body cavity in a surgical device. A second mode of operation for performing smoke evacuation in a filter element from insufflation fluid caused to recycle through the multimodal system from the body cavity via a surgical device. A third mode of operation for providing insufflation fluid from the insufflation gas source into the body cavity for creating and maintaining insufflation of the body cavity.

Multimodal surgical gas delivery system for laparoscopic surgical procedures

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 and a second coupling to couple to a secondary trocar assembly. A third coupling is provided to couple to a source of pressurized fluid for directing pressurized fluid from the source to the first and second couplings. Also provided is at least one valve member adapted and configured to be operable in at least first and second operating positions.
