Abstract
A filtration system for collecting bone fragments during surgery performed on a patient includes a cylinder having a rotating disk with circumferential arms extending radially in the cylinder to define pockets. The rotating disk includes a longitudinal hub that carries an outlet connected to a central passageway formed in the disk. A plurality of apertures on the disk permit the liquid to flow into the passageway and through the outlet while the pockets retain the bone fragments. The disk is rotated to align circumferential spaced pockets to align with the inlet and outlet ports. The disks includes bearing surfaces that permit the rotation thereof and the arms are spaced from the cylinder inner surface to allow the flow of fluid in the event the pockets fill and clog the apertures and prevent flow into the outlet passage.
