Disclosed is a bone coring device having a handle including a first handle component and a second handle component. The first handle component is rotatably coupled to the second handle component. The device also includes a coring assembly mechanically coupled to the handle. The coring assembly includes an elongated outer cutting member having an internal bore and distal edge adapted to cut through cancellous bone. The coring assembly also includes an elongated inner member slidably positioned within the internal bore of the outer cutting member. Rotatable movement of the first handle component relative to the second handle component causes relative, linear movement between the elongated outer cutting member and the inner member to facilitate coring of a sample of bone when the coring assembly is positioned within the bone. |
