ABSTRACT:
A double cutting blade with a center vertical blade, which slices a margin of tissue around the surgical site. This blade permits thereby the positive establishment of tumor or diseased tissue limits by delineating the margin of normal tissue that is free of tumor or diseased tissue.
The vertical blade of the margin blade cuts a strip of skin or tissue out to form a trench of a width the same as the width between the knives wherever the margin blade, sometimes called a trenching blade, travels so that the resultant trench conforms exactly to the normal tissue surrounding the diseased tissue or tumor, thereby saving as much normal tissue as possible.
