Abstract

See full text

An apparatus for cutting a workpiece as biospecimen into a section while maintaining living state of cells includes a board on which the workpiece is placed, a device for freezing and fixing the workpiece on the board, and a blade for cutting the frozen workpiece fixed on the board into a section by means of rotary movement in a predetermined rotational direction. A profile of a cutting edge of the blade is a curve showing monotonic increase in distances of a rotational axis to points starting at a nearest point that is the shortest from the axis and ending at a farthest point that is the longest from the axis. The farthest point is behind the nearest point in the rotational direction and the curve is convex opposite to the rotational axis with respect to a straight line connecting the nearest point and the farthest point.
