Abstract
A collector includes a container body defining an interior containment space and having an open end for access, and a cap in covering relation to the open end and having an opening for receiving therein a distal end of a kerrison-type rongeur. An improvement includes the cap including a first plurality of scrapers in the form of fingers for engaging and dislodging cut bone from the cutting area of the distal end of the rongeur and a second plurality of scrapers in the form of wipers for engaging and dislodging cut bone from the cutting area of the distal end of the rongeur when the distal end of the rongeur is withdrawn through the opening from the collector, the second plurality being arranged so as to permit insertion of the distal end of the rongeur through the opening into the collector without engaging the distal end of the rongeur.
