  • Method of using a dermatome
    Patent number: 4838284
    Abstract: A dermatome is disclosed which includes a heavy metallic base, a hollow stem vertically supported upon the base, a blade carrying crosshead horizontally reciprocal within the base, a vertically movable plunger assembly adjustably secured within the stem and a bottom plate bottomly secured to the base below the reciprocating blade. The plunger assembly bottomly carries a replaceable pin and the bottom plate is provided with a cooperating operation to receive the pin therethrough. An operating lever pivotally secures to a yoke that is affixed to the stem and is used to urge the crosshead to an initial, cocked position. A safety pin is adjustably positioned in the yoke to prevent firing of the crosshead without first depressing the safety pin. In use, the crosshead is cocked and the plunger assembly pin is lowered through the opening to adhere to a skin specimen. Upon raising the plunger assembly, the skin specimen is drawn upwardly through the plate opening and above the plane of travel of the crosshead blade.
