摘要

A biopsy device (10) is provided which includes a localization needle (62) having a guide wire (66) preloaded into the biopsy device. The device includes a stylet (18) having a blade (16, 17) for transecting and separating tissue. The device further includes a cannula (14) for cutting a core of tissue and a garrote wire (74) for cutting a transection of tissue transverse to the core cut by the cannula. The garrote wire is activated by a trigger mechanism (26) which is locked out by a lockout feature within the device until the garrote wire has been advanced around the core of tissue cut by the cannula.
