Abstract
A vane compressor for a surgical gas delivery system is disclosed, which includes a compressor head having an outlet port for delivering pressurized gas to a gaseous sealing manifold communicating with a gas sealed trocar and an inlet port for receiving spent gas from the gaseous sealing manifold by way of the gas sealed trocar, wherein the compressor head is coupled to and driven by a motor.
Claims22
A vane compressor assembly for a surgical gas delivery system comprising:
- a) a compressor head having an outlet port for delivering pressurized gas to a gaseous sealing manifold communicating with a gas sealed trocar and an inlet port for receiving spent gas from the gaseous sealing manifold by way of the gas sealed trocar;
- b) a pump body operatively associated with the compressor head and defining a cylindrical bore having a central axis;
- and
- c) a hub mounted for rotation within the cylindrical bore of the pump body about a shaft that defines an axis of rotation of the hub, wherein the axis of rotation of the hub is offset from a central axis of the cylindrical bore, and wherein the hub contains a plurality of circumferentially spaced apart vane slots each containing a freely sliding vane.
