Vane compressor for surgical gas delivery system with gas sealed insufflation and recirculation

A surgical gas delivery system comprising:

• a) a manifold for communicating with a gas sealed access port;
• b) a proportional fill valve for dynamically controlling delivery of a gas into the manifold from a gas source;
• c) a positive displacement rotary vane compressor assembly for recirculating the gas through the gas sealed access port by way of the manifold, the positive displacement rotary vane compressor assembly including a compressor head having an inlet port on a first side surface of the compressor head for receiving a spent gas flow from the gas sealed access port through the manifold and an outlet port on a second side surface of the compressor head for discharging a pressurized gas flow to the gas sealed access port through the manifold;
• d) a pump body extending from a front surface of the compressor head;
• e) a brushless direct current motor coupled to a rear surface of the compressor head for driving the positive displacement rotary vane compressor assembly;
• and
• f) an intercooler and/or a condenser interposed between the manifold and the positive displacement rotary vane compressor assembly for conditioning the spent gas flow received by the positive displacement rotary vane compressor assembly from the manifold and for conditioning the pressurized gas flow discharged from the positive displacement rotary vane compressor assembly to the manifold,
• wherein the spent gas flow travels directly from an outlet of the manifold to a first inlet of the intercooler and/or the condenser and then from a first outlet of the intercooler and/or the condenser to the inlet port of the compressor head, and the pressurized gas flow travels directly from the outlet port of the compressor head to a second inlet of the intercooler and/or the condenser and then from a second outlet of the intercooler and/or the condenser to an inlet of the manifold.
