contemplated a tissue mincing tool can include a second cutting surface to further reduce the average cross section of the minced tissue samples examples of a cutting surface include a grate with sharp edges multiple sharp wires across an opening a steel plate or disc with multiple holes resting on a lip inside a compartment holes in a plate that are offset and have a sharp edge and a mesh of sharp surfaces defining apertures additionally or alternatively in an embodiment in which a cutting surface defines apertures an end of the plunger 104 can form multiple projections such as fingers that mate with the apertures of the cutting surface 108 to assist in pushing the tissue sample through the cutting surface 108 in an alternative embodiment the end of the plunger 104 can be flat moreover the cutting surface 108 can be textured or can form multiple projections e g a cleat to create a frictional surface or to keep the tissue sample on the cutting surface 108 as pressure is applied to the tissue sample in a further embodiment the cutting surface 108 may include an automated cutting system such as a semi automatic scissors in an embodiment an optional nose nut not shown may be disposed about the cutting surface 108 to retain the cutting surface 108 in position as a tissue sample is being impelled therethrough for example the optional nose nut can.
