Patent ID: 7895885

Claim:
A microsurgery nanoknife able to cut living tissues comprising: a blade body having a roughly quadrangular cantilever base surface, two opposite roughly triangular side surfaces, and two opposite roughly regular trapezoid side surfaces, said side surfaces meeting to form an edge; said blade body is a self-supporting thin film structure with a hollow cross-section that forms a near atomically sharp edge able to cut living tissues while not destroying tissue viability so that the tissues can be repaired or engrafted; the self-supporting thin film structure has a thickness that is at least about 10 times larger than the radius of curvature of the near atomically sharp edge; wherein said base cantilever portion can be used for attachment to a micromanipulator for positional control; and wherein said edge is less than about 200 microns long; and a self-leveling frame that automatically aligns the nanoknife edge with a cutting surface.
