ABSTRACT:
A biopsy needle has coaxial, telescopically interengaged stylet, inner and outer cannulas which are axially and rotatably displaceable relative to one another. The stylet has a distal portion provided with a cutting recess for severing a biopsy specimen from a site in a patient, and the inner cannula has a distal portion for cutting and capturing the specimen in the recess for removal from the site upon withdrawal of the needle from the patient. The distal portion of the inner cannula is partially cut away to provide an insert recess which supports a semi-circular insert of hemostatic collagen which remains at the site upon removal of the needle to minimize hemorrhagic complications by promoting blood clotting. The insert and the distal portion of the inner cannula have radially outer surfaces of corresponding radius whereby the distal portion of the inner cannula and the insert supported thereon are received within the distal end of the outer cannula prior to use of the needle.
