Separable two-part single lumen gas sealed access port for use during endoscopic surgical procedures

A surgical access port for performing an endoscopic surgical procedure in a surgical cavity of a patient, comprising:

• a proximal housing and an elongated single lumen tubular body portion extending distally from the proximal housing and defining a central cannula, the proximal housing having an inlet path for communicating with a pressurized gas line of a tube set and an outlet path for communicating with a return gas line of the tube set, the housing accommodating an annular jet assembly that includes an upper jet ring having a nozzle tube and a lower jet ring defining a nozzle seat for receiving the nozzle tube, wherein the annular jet assembly is configured for receiving pressurized gas from the inlet path and for generating a gaseous sealing zone within the central cannula of the associated tubular body portion to maintain a stable pressure within the surgical cavity of the patient, wherein the proximal housing portion includes diametrically opposed spring biased latches for detachably engaging the tubular body portion.

A surgical access port for performing an endoscopic surgical procedure in a surgical cavity of a patient, comprising:

• a disposable gas sealed housing portion configured for attachment with a reusable single lumen tubular body portion configured for robotic manipulation and defining a central cannula, the housing portion having an inlet path for communicating with a pressurized gas line of a tube set and an outlet path for communicating with a return gas line of the tube set, the housing portion accommodating an annular jet assembly that includes an upper jet ring having a nozzle tube and a lower jet ring defining a nozzle seat for receiving the nozzle tube, wherein the annular jet assembly is configured for receiving pressurized gas from the inlet path and for generating a gaseous sealing zone within the central cannula of the tubular body portion to maintain a stable pressure within the surgical cavity of the patient.
