ABSTRACT:
A surgical instrument for taking biological samples from the interior of a living human or animal body is provided. It comprises a tubular needle with a tubular stiletto snugly and slidably fitted therein, the distal end of said tubular stiletto being sharpened. The stiletto contains optical fiber means for directing light into the interior of the body and for directing reflected light therefrom and is provided with fine air ducts, which, when subjected to a partial vacuum, cause the stiletto to slide forward through the needle into abutment on the interior surface from which a biological sample is to be taken.
