1. An apparatus for collecting particulate bone during a craniotomy, comprising:
a craniotome tool having a tool body with a distal end, a bone cutting or drilling bun and a foot plate extending out from the distal end of the tool body, the foot plate extending beyond the bone cutting or drilling burr and the bone cutting or drilling bun having a diameter; a collection module adapted for removable engagement with the distal end of the tool body of the craniotime tool, the collection module having a housing comprising:
a cavity accommodating therein the distal end of the tool body, a proximal end of the housing having a flexible bellow portion, and a distal end of the flexible bellow portion having a protruding lip adapted to seal a radial space in the cavity between the flexible bellow portion and the distal end of the tool body accommodated therein, the protruding lip extending from and forming part of an inner wall of the flexible bellow portion to prevent debris from entering the radial space;a transparent shield portion extending from the distal end of the flexible bellow portion;an end wall forming part of a dome-shaped end portion extending from a distal end of the transparent shield portion, the end wall having a slot sufficiently larger than the diameter of the bone cutting or drilling burr to permit the bone cutting or drilling burr to extend therethrough; anda suction channel disposed in the cavity in suctioning communication with the slot. |
