ABSTRACT:
An improved rotary biopsy device for extracting biopsy samples and the like from specific specimen extracting locations. The device includes an elongated inner needle member used for initial penetration of the body tissue, with an outer hollow cylindrical cutting tube thereafter being slidably received over the needle member. In use, the needle member is first penetrated, by rotating same, into the desired specimen extracting location. The outer tube is then slidably disposed thereover and pushed downwardly until it also penetrates the body tissue, and both the tube and needle are simultaneously withdrawn with the sample collected interiorly of the tube.
