Abstract:
A surgical evacuation apparatus and method for evacuating a biological material from a body cavity. The surgical evacuation apparatus has a shaft and a scoop extending from a distal end of the shaft. The shaft has a supply inlet for connecting to a pressurized fluid source and an outlet for connecting to a vacuum source. An evacuation channel extends from the scoop to the outlet. A fluid supply channel extends in the shaft from the supply inlet towards the distal end and intersects the evacuation channel proximate the scoop. Material desired to be removed from the body cavity is collected in the scoop by a user. The biological material collected in the scoop is broken up by a fluid stream from the supply channel and is drawn into the evacuation channel by a vacuum applied by the vacuum source and is removed from the body cavity.
