    Abstract: A gas sealed access cap for a robotic cannula comprising a housing having a lid defining a central access port extending to an interior cavity that supports an annular jet assembly for receiving pressurized gas from an inlet port of the housing, wherein the annular jet assembly includes a central aperture aligned with the central access port of the lid and is adapted to generate a gaseous sealing zone within the robotic cannula to maintain a stable pressure within the surgical cavity of a patient; a plurality of circumferentially spaced apart radially inwardly extending vanes formed integral with the housing and located within the interior cavity thereof below the annular jet assembly for directing spent gas from the gaseous sealing zone to an outlet port of the housing; and a central access tube aligned with the central access port of the housing and the central aperture of the annular jet assembly, and extending distally from the interior cavity of the housing below the vanes for communicating with a tubular portion of the robotic cannula, wherein the housing of the access cap is dimensioned and configured for reception within a proximal bowl portion of the robotic cannula.
