ABSTRACT:
A bone particle collecting unit (30) has first (32) and second (34) interfitting housing members capturing a cylindrical screen basket assembly (64). Bone particle containing effluent from a surgical site is received through a port (40) in the first housing member (32) into the screen basket assembly (64). Suction is applied from a port (56) in the second housing member (34) to remove liquid which passes through the screen basket assembly. The screen basket assembly (64) includes a disc (66) which frictionally receives one end of a cylindrical screen (70) with the other end o the screen received about a rib (42) formed in the first housing member (32). Disc (66) of the screen basket assembly is received on guide ribs (58) to seat the assembly in the second housing member (34). After removing the screen basket assembly (64) from the housing members a plunger (86) can be inserted into the open end of the assembly to consolidate the bone particles and to expel the consolidated bone particles onto a collection surface (98).
