Bone fragment collector and processor

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

• a housing having a distal end and a proximal end, said housing comprising an outer wall having an inner surface extending between said distal end and said proximal end and a window portion which allows light to pass therethrough;
• a filter element at least partially disposed within said housing, said filter element having:
• a first end;
• a second end, said first end positioned closer to said distal end of said housing than said second end;
• a sidewall joining said first end and said second end, said sidewall defining an inner peripheral surface and an outer peripheral surface, said sidewall having a plurality of apertures therein, wherein said inner peripheral surface of said sidewall at least partially defines a collection chamber for collection of a composition comprising bone fragments, said outer peripheral surface of said sidewall and said inner surface of said outer wall are spaced apart from one another to define an exterior radial volume;
• and
• a piston moveably disposed within said filter element and movable between a first and a second position, wherein said piston at least partially defines said collection chamber in said first position and is at least partially visible through said window portion in said outer wall;
• an intake port configured to be coupled to a surgical tool and receive said composition comprising bone fragments;
• a vacuum port configured to be coupled to a vacuum source;
• and
• a plunger configured to be releasably coupled to said piston to move said piston between said first and second positions,
• wherein said plunger can be coupled to said piston while being viewed through said window, and force can be applied to said piston to move said piston from said first position to said second position to discharge composition from said filter element.

• and
• a piston comprising an attachment element and moveably disposed within said filter element and movable between a first and a second position, wherein said piston at least partially defines said collection chamber in said first position;
• an inlet cap releasably coupled to said distal end of said housing and/or said first end of said filter element, said inlet cap including an intake port configured to be coupled to a surgical tool and receive said composition comprising bone fragments;
• an outlet cap releasably coupled to said proximal end of said housing, said outlet cap including a vacuum port configured to be coupled to a vacuum source;
• and
• a plunger configured to be releasably coupled to said piston to move said piston between said first and second positions, said plunger comprising a corresponding attachment element, a press pad, and a tapered body extending therebetween, wherein said body is tapered such that a diameter of said body increases as said body extends from said corresponding attachment element towards said press pad,
• wherein upon removal of said inlet cap and said outlet cap, said plunger can be coupled to said piston, and force can be applied to said piston to move said piston from said first position to said second position to discharge composition from said filter element.
