Claim 0:
1. A bone biopsy system comprising:
a cutting assembly comprising:
a cutting cannula that comprises a cutting tip positioned at a distalmost end thereof and that defines a lumen, the cutting tip being configured to cut bone; and
a first hub attached to the cutting cannula, the first hub comprising a first connection interface;

an insert assembly comprising:
an elongated insert sized to be received within the lumen of the cutting cannula, the elongated insert comprising a distal tip; and
a second hub attached to the elongated insert, the second hub comprising a driver connector and further comprising a second connection interface configured to cooperate with the first connection interface to rotationally lock the second hub relative to the first hub; and

a manual handle either coupled to or couplable with the first hub so as to be rotationally locked relative to the first hub,
the bone biopsy system being selectively convertible from a power drilling configuration to a manual coring configuration,
wherein, when the bone biopsy system is in the power drilling configuration, the insert assembly is coupled with the cutting assembly such that:
the elongated insert is received within the lumen of the cutting cannula such that the distal tip of the elongated insert:
is positioned distal to the cutting tip of the cutting cannula;
sits flush with a portion of the cutting tip; or
sits slightly recessed relative to a portion of the cutting tip while the elongated insert prevents material from entering the cutting cannula;

the first and second connection interfaces cooperate to rotationally lock the second hub relative to the first hub; and
the driver connector is couplable to a powered driver to permit the powered driver to rotate the insert assembly and the cutting assembly in unison, and

wherein, when the bone biopsy system is in the manual coring configuration, the insert assembly is decoupled from the cutting assembly and the handle is coupled with the first hub to permit manual rotation of the cutting assembly.
