Multi-port, high-flow pneumoperitoneum and smoke evacuation distribution devices, systems, and methods

An insufflation system for creating a high-flow, constant or variable pressure pneumoperitoneum, the system comprising:

• a gas flow distribution device comprising:
• a single-piece housing defining an insufflation chamber;
• a single inlet port on the housing in direct fluid communication with the insufflation chamber without any intervening components therebetween, the inlet port configured to be connected to an insufflator to provide pressurized insufflation gas from the insufflator to the insufflation chamber, the inlet port extending outwardly away from the housing;
• and
• a plurality of outlet ports on the housing in direct fluid communication with the insufflation chamber without any intervening components therebetween, the plurality of outlet ports configured to be connected to a plurality of insufflation trocars inserted in a single cavity of a patient, each outlet port configured to be connected to a dedicated one of the plurality of insufflation trocars, to concurrently distribute the pressurized insufflation gas from the insufflation chamber to each of the plurality of insufflation trocars and into the single cavity, each outlet port extending outwardly away from the housing,
• wherein, with the exception of the inlet port and the plurality of outlet ports, the housing is free of any openings in fluid communication with the insufflation chamber, and
• wherein the housing further defines an exhaust chamber, the insufflation system further comprising:
• at least one exhaust inlet port on the housing and configured to be connected to an exhaust trocar to provide suction and/or evacuate smoke from the exhaust trocar to the exhaust chamber;
• and
• an exhaust outlet port on the housing and configured to be connected to an exhaust device to provide exhaust from the exhaust chamber to the exhaust device.
