Bone Fragment Collector and Processor

A device for collecting and processing bone fragments, said device comprising:

• a housing including a distal end, a proximal end, and an outer wall having an inner surface extending between the distal end and the proximal end;
• a filter element at least partially disposed within the housing, the filter element having:
• a first end;
• a second end, the first end positioned closer to the distal end of the housing than the second end;
• a side wall joining the first end and the second end, the side wall defining an inner peripheral surface and an outer peripheral surface, the side wall having a plurality of apertures therein, wherein the inner peripheral surface of the side wall at least partially defines a collection chamber for the collection of a composition comprising bone fragments, the outer peripheral surface of the side wall and the inner surface of the outer wall are spaced apart from one another to define an exterior radial volume, and a portion of the side wall is tapered such that the cross-sectional area of the collection chamber in the longitudinal direction of the filter element increases as the side wall extends from the second end towards the first end;
• and
• a piston moveably disposed within the filter element and movable between a first and a second position, wherein the piston at least partially defines the collection chamber in the first position;
• an inlet cap releasably coupled to the distal end of the housing and/or the first end of the filter element, the inlet cap including an inlet port configured to be coupled to a surgical tool and receive the composition comprising bone fragments;
• and
• an outlet cap releasably coupled to the proximal end of the housing, the outlet cap including an outlet port configured to be coupled to a vacuum source;
• wherein the composition is acquired through the inlet port and collected in the collection chamber, and upon removal of the inlet cap and the outlet cap, force can be applied to the piston to move the piston from the first position to the second position such that the tapered side wall facilitates the discharge of the composition from the filter element.

A surgical system for collecting and processing bone fragments with a bone collection device, said surgical system comprising:

• a housing including a distal end, a proximal end, and an outer wall having an inner surface extending between the distal end and the proximal end;
• a filter element disposed within the housing, the filter element having:
• a first end;
• a second end, the first end positioned closer to the distal end of the housing than the second end;
• a side wall joining the first end and the second end, the side wall defining an inner peripheral surface and an outer peripheral surface, the side wall having a plurality of apertures therein, wherein the inner peripheral surface of the side wall at least partially defines a collection chamber for the collection of a composition comprising bone fragments and the outer peripheral surface of the side wall and the inner surface of the outer wall are spaced apart from one another to define an exterior radial volume;
• and
• a piston moveably disposed within the filter element movable between a first and a second position;
• a shaft configured to be coupled to the piston to move the piston between the first and second positions, wherein the piston at least partially defines the collection chamber in the first position;
• an inlet cap releasably coupled to the distal end of the housing or the first end of the filter element, the inlet cap including an inlet port configured to be coupled to a surgical tool and receive the composition comprising bone fragments;
• and
• an outlet cap releasably coupled to the proximal end of the housing and in fluid communication with the housing, the outlet cap including an outlet port configured to be coupled to a vacuum source;
• wherein the inlet cap and the outlet cap are configured to be coupled to one another such that after the composition is acquired through the inlet port and collected in the collection chamber and the inlet cap and the outlet cap have been removed from the housing to harvest the composition, the inlet cap and the outlet cap can be coupled to one another to restore vacuum airflow to the surgical tool.
