A device for use with a biopsy cannula includes a housing and a locking assembly. The housing defines a shaft aperture sized to receive and at least partially circumferentially encompass a biopsy cannula. The locking assembly defines a lock opening configured to receive the biopsy cannula. The locking assembly includes a pair of lock members extending inwardly within the lock opening. The pair of lock members are configured to bind against the biopsy cannula upon translation of the locking assembly relative to the lock opening to a locking position. The locking member and the housing are configured to restrict the depth of insertion of the biopsy cannula through the lock opening when the pair of lock members are bound against the biopsy cannula in the locking position.
