Abstract
Abstract Surgical instrument for taking tissue specimens in which a pair of coaxial tubular members are provided which are formed to have a tissue specimen receiving or flow compartment or provisions for holding the tissue. Each of the tubular members has a cutting or a holding edge and suction is provided through the instrument for drawing the specimen into the tissue receiving or tissue flow compartment. Movement of one of the tubular members relative to the other causes the tissue specimen to be cut and placed in the compartment or to be just cut and held in place.
