  • Patent number: 10595831
    Abstract: An exemplary biopsy system includes a biopsy device having a probe. The probe includes a distally extending needle and a cutter movable relative to the needle. The probe also includes a tissue sample holder detachably coupled to the proximal end of the probe. The biopsy system has a cycle where the biopsy system provides vacuum to the biopsy device, retracts the cutter to a proximal position, advances the cutter to a distal position, and transports a sample to the tissue sample holder. The biopsy system is capable of adjusting the duration of its cycle during operation of the biopsy device.

  • Publication number: 20170000467
    Abstract: A biopsy device comprises a body, a needle, and a cutter actuation mechanism. The needle extends distally from the body. The cutter actuation mechanism rotates and translates the cutter relative to the body and relative to the needle. The cutter has an overmold presenting a lead screw and a hex portion. The cutter actuation mechanism comprises a first gear disposed about the hex portion of the overmold and a second gear engaged with the lead screw of the overmold by a nut that is integral with the second gear. The cutter actuation mechanism is operable to simultaneously rotate the first gear relative to the body at a first rotational speed and the second gear relative to the body at a second rotational speed. With the lead screw and the nut rotating at different rotational speeds, the lead screw rotates relative to the nut at a third rotational speed.
