Title:
多モード外科用気体送達システムのための一体化された気密シールを伴う多経路濾過アセンブリ
Document Type and Number:
Japanese Patent JP6578052
Kind Code:
B2
Abstract:
A gas conditioning unit (30) for a surgical gas delivery device (12) is disclosed, which includes a filter housing (50) having an insufflation gas flow path (210) for delivering insufflation gas to a body cavity and for facilitating pressure measurements from the body cavity, a pressurized gas flow path (220) for delivering pressurized gas from a pump (20) in the surgical gas delivery device (12) to an internal nozzle (150) in the filter housing (50) that accelerates the pressurized gas and thereby generates a continuous pressure barrier that inhibits egress of insufflation gas from the body cavity, a vacuum return flow path (230) for returning depressurized gas spent by the internal nozzle (150) back to the pump (20) under vacuum, an air entrainment flow path (250) for drawing air into the body cavity to maintain a given pressure therein, and a smoke evacuation flow (240) path for conveying smoke from the body cavity.
