A system for performing an endoscopic surgical procedure in a surgical cavity of a patient that includes a gas delivery device configured to deliver a flow of pressurized gas to a gas delivery lumen extending therefrom, a gaseous sealing module communicating with a distal end of the gas delivery lumen and configured to generate a gaseous seal within a gas sealed lumen extending therefrom, and an access port communicating with a distal end of the gas sealed lumen so as to provide sealed instrument access to the surgical cavity and maintain a stable pressure within the surgical cavity.

Embodiments of the present disclosure provide an apparatus and method for reducing surgical smoke. An exemplary apparatus includes trocar comprising a tubular hollow body circumscribing a cavity extending through a longitudinal axis of the trocar with a gasket at a first end and an exit port at a second end, the tubular hollow body comprising a first wall circumscribing the cavity and a concentrically spaced apart second wall. The apparatus further includes a first plate operable to maintain an electric charged disposed within the cavity on the first wall, and a second plate operable to maintain an electric charge disposed between the first wall and the spaced apart second wall.

A filter cartridge for a surgical gas delivery system is disclosed which includes a housing having a front end and a rear end and defining a first interior flow path extending downstream from a first inlet at the rear end of the housing to a first outlet at the front end of the housing, and a second interior flow path extending upstream from a second inlet at the front end the housing to a second outlet at the rear end of the housing, a first pleated filter element operatively associated with the first interior flow path, a second pleated filter element operatively associated with the second interior flow path, and a carbon filter disc operatively associated with the second interior flow path and positioned adjacent a downstream side of the second pleated filter element.

A surgical humidification system includes a source of gas flow and a humidifier that receives the gas flow and outputs a humidified gas to a delivery conduit. The delivery conduit has an outlet and a suitable interface, such as a diffuser, is connected to the outlet. The interface can be positioned near or within an open surgical cavity of a patient to supply the humidified gas to the cavity. The system also includes a pressure relief arrangement that operates to relieve pressure from the system above a normal operating pressure. The pressure relief arrangement can be located in a non-sterile portion of the system, such as upstream from the humidifier, for example.

An insertion instrument includes a shaft projecting, by being inserted through a hole of a fixing instrument, from a distal end of the fixing instrument toward a distal side, and a gas supply channel formed in the shaft section and having a jet port, which jets a gas, in a distal portion of the shaft section. The gas is supplied from a proximal side to the distal side toward the jet port in the gas supply channel, and an extension dimension along the longitudinal axis from the jet port toward the proximal side is greater than an extension dimension of the hole of the fixing instrument.

A system for performing an endoscopic surgical procedure in a surgical cavity of a patient that includes a gas delivery device configured to deliver a flow of pressurized gas to a gas delivery lumen extending therefrom, a gaseous sealing module communicating with a distal end of the gas delivery lumen and configured to generate a gaseous seal within a gas sealed lumen extending therefrom, and an access port communicating with a distal end of the gas sealed lumen so as to provide sealed instrument access to the surgical cavity and maintain a stable pressure within the surgical cavity.

A surgical gas delivery system is disclosed for gas sealed insufflation and recirculation during an endoscopic or laparoscopic surgical procedure, which includes a gaseous sealing manifold for communicating with a gas sealed access port, a compressor for recirculating gas through the gaseous sealing manifold, and a source of UVC irradiation for sterilizing at least the gas recirculating through the gaseous sealing manifold.

A surgical gas delivery system is disclosed for gas sealed insufflation and recirculation, which includes a gaseous sealing manifold for communicating with a gas sealed access port, an insufflation manifold for communicating with the gas sealed access port and with a valve sealed access port, a compressor for recirculating gas through the gas sealed access port by way of the gaseous sealing manifold, a first outlet line valve associated with the insufflation manifold for controlling a flow of insufflation gas to the gas sealed access port, a second outlet line valve associated with the insufflation manifold for controlling a flow of insufflation gas to the valve sealed access port, and a proportional valve associated the insufflation manifold and located upstream from the first and second outlet line valves for dynamically controlling the flow of insufflation gas to the first and second outlet line valves.

A vane compressor for a surgical gas delivery system is disclosed, which includes a compressor head having an outlet port for delivering pressurized gas to a gaseous sealing manifold communicating with a gas sealed trocar and an inlet port for receiving spent gas from the gaseous sealing manifold by way of the gas sealed trocar, wherein the compressor head is coupled to and driven by a motor.

A manifold assembly for a surgical gas delivery system is disclosed, which includes a manifold body including an inlet port for receiving gas from an outlet side of a compressor and an outlet port for recirculating gas to an inlet side of the compressor, a bypass valve communicating with the inlet port and the outlet port of the manifold body, an air ventilation valve for dynamically controlling the ingress of air from atmosphere, a smoke evacuation valve for dynamically controlling the egress of gas from the manifold assembly when the gas delivery system is operating in a smoke evacuation mode, and a gas fill for dynamically controlling the receipt of gas from a source of surgical gas.
