A core biopsy device comprises a cutting cannula provided at a distal end with a helical excising blade. The cutting cannula can be rotated within a tissue mass so that the helical excising blade can excise a biopsy sample from the surrounding tissue.

Core biopsy device

Water timer

A core biopsy device comprises an outer cutting cannula in telescoping register with an inner spoon cannula. The outer cutting cannula is provided at a distal end with an arcuate excising blade that is biased radially inwardly to extend beyond the longitudinal axis of the cannula. The inner spoon cannula terminates at a distal end in an arcuate wall to form a biopsy sample spoon for supporting a biopsy sample thereon. The outer cutting cannula can be rotated relative to the inner spoon cannula so that the excising blade can excise the biopsy sample from the surrounding tissue. After removal of the core biopsy device from the tissue, the outer cutting cannula can be retracted away from the inner spoon cannula to reveal the biopsy sample and enable the sample to be removed from the biopsy device in a relatively undisturbed condition.
