title: A counter rotating power drill for needle biopsy.
abstract: A new needle biopsy instrument and technique are described. The needle is powered and due to its scissor-like arrangement can provide a core of both soft and hard tissue, preserving histologic detail. The needle has been used in 25 patients, in all of whom an appropriate specimen was obtained.
