ABSTRACT:
A biopsy device consisting of a housing, a coring section on the housing having a cylindrical wall with a leading cutting edge to be bored into a tissue from which a biopsy sample is to be taken and an internal hollow space bounded by an inside surface of the cylindrical wall for accepting a sample of a tissue which the cutting edge has penetrated; a severing blade with a severing edge mounted to the cylindrical wall at least partially inside of the hollow space for pivoting movement between (a) a first position wherein the severing edge is adjacent to the inside wall surface and (b) a second position wherein the severing edge is radially inwardly with respect to the cylindrical wall from the position of the severing edge in the first position, so that as the severing blade moves from the first position to the second position, the severing edge cuts across a tissue core in the internal hollow space to allow the core to be separated from the remainder of the tissue; and structure for selectively moving the severing blade between its first and second positions.
