Abstract: Described are a micro punch cutting tool and associated method that can be used under a microscope to accurately excise a targeted piece of material on a micron or millimeter scale. An example device for targeted material excision from a tissue sample includes a support defining an opening and providing a region below the opening for positioning a tissue sample. A tissue stabilizer is receivable in the opening and defines a shape that complements a shape of the support. A cutting tool assembly receivable in the tissue stabilizer includes a hollow cutter having a bore and is movable relative to the tissue stabilizer to cause the cutter to excise material from the tissue sample when the tissue sample is positioned below the opening of the support. Movement of the cutting tool assembly is guided by a helical groove in the tissue stabilizer engaging a protrusion of the cutting tool assembly.
