Sistema multimodal de circulación de gas para uso en procedimientos quirúrgicos endoscópicos

A multi-modal gas delivery device is disclosed for performing an endoscopic surgical procedure in a surgical cavity, which includes an insufflation subunit for delivering insufflation gas from a gas source to the surgical cavity and for sensing pressure within the surgical cavity, and a primary gas circulation pump for delivering pressurized gas to a gas sealed access port so as to generate a gaseous seal therein and thereby maintain a stable pressure within the surgical cavity and for receiving gas returning from the gas sealed access port that was used to form the gaseous seal, and a secondary gas circulation pump for continuously evacuating smoke filled gas from the surgical cavity, regardless of the sensed pressure within the surgical cavity.
