ABSTRACT:
A collector unit for collecting tissue or bone from a dental patient during a dental implant procedure generally includes a cover member, a filter support member, a filter medium and a gasket member. The support member is mountable within the cover member with the gasket member positioned therebetween to form the unit. A passage is provided through the unit to allow the passage of fluid material through the unit. The support member has a pair of spaced-apart, opposed filter support arms for removably supporting a substantially flat section of filter medium so that the filter medium overlies the inlet passage such that fluid material passing through the unit must pass through the filter medium which will filter out any bone or tissue specimens. The filter medium is removable from the supporting structure so that it can be positioned in a flat-orientation to facilitate the removal of bone or tissue specimens therefrom. Once removed, the filter medium cannot be reattached to the supporting structure. A pair of latch arms releasably secure the cover member and the support member together. The gasket member provides an integral one-way valve which normally blocks the inlet passage and can be moved out of association with the inlet passage to provide a path for the flow of fluid material through the unit.
