1. A system comprising:
a primary trocar comprising a lip, a single lumen, and a docking mount, the docking mount being configured to engage with a robotic arm of a surgical robot; and
a secondary trocar configured to be positioned at least partially within the primary trocar and being further configured to facilitate delivery of insufflation fluid to a patient cavity, the secondary trocar comprising:
a trocar head comprising one or more latches configured to engage the lip of the primary trocar to facilitate coupling of the primary trocar and the secondary trocar;
a double lumen comprising an outer lumen disposed about an inner lumen, the outer lumen comprising at least one sensor and one or more openings, the at least one sensor being configured to determine a pressure measurement indicative of a pressure of the patient cavity and the one or more openings configured to direct the insufflation fluid into the patient cavity; and
one or more conditioning elements configured to heat and/or humidify the insufflation fluid;
wherein, when the primary trocar and the secondary trocar are coupled:
a fluid seal exists between the primary trocar and the secondary trocar, the fluid seal being provided at least partially by a gasket;
the one or more openings in the outer lumen of the secondary trocar extend beyond the single lumen of the primary trocar; and
the insufflation fluid is supplied based on the pressure measurement.
