• a. a handle and a non-metallic elongated substantially tubular needle having a proximal end attached to said handle, a sharp distal end for insertion within tissue, and a longitudinal axis therebetween;
• b. said needle comprising right and left members on either side of said longitudinal axis, said right and left members each having upper and lower ends comprising a series of alternating male and female portions, wherein said male portions of said right member mate with said female portions of said left member and said male portions of said left member mate with said female portions of said right member to securely attach said two members together;
• and
• c. a means for obtaining a tissue sample within said elongated needle.
