1. A surgical evacuation apparatus for evacuating a biological material, comprising:
a shaft having a proximal end and a distal end, the proximal end having an inlet for connecting to a pressurized fluid source and an outlet for connecting to a vacuum source, and
a scoop extending from the distal end of the shaft and defining a material collecting cavity; and
wherein the shaft further comprises a supply channel and an evacuation channel, the evacuation channel starting at the distal end of the shaft and extending through the shaft from the distal end to the outlet in a way that the evacuation channel is in open communication with the material collecting cavity, and the supply channel extending through the shaft from the inlet towards the distal end and intersecting the evacuation channel at a location along the evacuation channel separate from an entirety of the material collecting cavity of the scoop such that the biological material collected in the material collecting cavity is drawn into the evacuation channel from the material collecting cavity when a vacuum is applied to the outlet and the biological material is broken up in the evacuation channel by a fluid stream passing into the evacuation channel from the supply channel to facilitate evacuation of the biological material.
