ABSTRACT:
A device for harvesting bone, including a hollow cylindrical rod having a sharpened distal end, a proximal end with a handle thereon, and a chamber therein extending axially between the proximal and distal ends. A plunger rod is inserted into the proximal end of the cylindrical rod, the plunger rod being slidable axially within the chamber. A sealing support is provided on the proximal end of the hollow cylindrical rod for engaging the plunger rod to establish a slidable hermetic seal therebetween and prevent retrograde flow of air into the chamber from the proximal end of the cylindrical rod. The device also includes a side opening in the cylindrical rod communicating with the chamber, which is connectable to a source of vacuum for evacuating fluid from the chamber into a fluid reservoir connectable to the side opening for collecting fluid therein.
