ABSTRACT:
A disposable blade holder for use with an apparatus, such as a microtome which is employed in cutting thin sections of tissue and other materials for microscope viewing. The blade holder is removably mountable in a microtome and secured therein by clamps. The holder comprises a cover plate and a base with a pair of small steps slightly greater in height than the thickness of a disposable blade. When a portion of the cover plate, disposed inwardly of the steps and otherwise suspended between them, is subjected to a sufficiently large force directed toward the base, the cover plate is deflected slightly and presses against the blade holding it firmly. The greatest deflection of the cover plate occurs in its mid-section so that the cover plate comes into contact with the blade first before it can touch the remainder of the base. The same clamps used to secure the blade holder itself to the microtome also serve to keep the cover pressed against the blade. This method of securing the blade eliminates the need for the holder to have its own clamping means. The holder, which lacks any moving parts, has only smooth surfaces without any pockets in which to collect debris, facilitating cleaning and sterilization.
