摘要：
An apparatus for morcellating tissue specimens comprises a housing and a cutting member. The cutting member is operable to cut tissue specimens into morcellated or minced tissue pieces. The cutting member may include one or more screens. One of the screens may be rotatable or capable of reciprocating relative to the housing. One screen may cooperate with another screen to provide shearing of the tissue specimens. The cutting member may include a plurality of discs that are rotatable relative to the housing. The discs may include inwardly directed notches formed in their outer perimeter, with the notches cooperating with an interior wall of the housing to cut tissue specimens. The discs may include perimeters having ovular or elliptical shapes that cooperate with a cylindrical interior wall of the housing to cut tissue specimens. The apparatus may be a stand-alone apparatus or may be incorporated into a tissue harvesting apparatus.
