摘要： 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.

摘要： A biopsy device comprises a body, a needle, a cutter, and a shuttle valve slider. The needle has a first lumen and a second lumen. The cutter translates relative to the needle. The shuttle valve slider translates in response to translation of the cutter. The shuttle valve slider vents the second lumen when the shuttle valve slider is in a first longitudinal position and substantially seals the second lumen relative to atmospheric air when the shuttle valve slider is in a second longitudinal position. A degree of lost motion is provided between the cutter and the shuttle valve slider, such that the cutter moves the shuttle valve slider only when the cutter moves through a first part of the cutter's range of motion; and such that the cutter does not move the shuttle valve slider when the cutter moves through a second part of the cutter's range of motion.

摘要： A method of biopsy device operation comprises rotating a first rotating member at a first rotational speed to rotate a cutter. A second rotating member is rotated at a second rotational speed to translate the cutter. The first and second members are rotated simultaneously and in the same direction. The first rotating member rotates with the cutter, while the second rotating member rotates about the first rotating member. The difference between the first and second rotational speeds, as well as threaded engagement between the first and second rotating members, provides the translation of the cutter. A method of biopsy device operation also comprises moving a shuttle valve slider to selectively vent or seal the second lumen of a needle. The shuttle valve slider is responsive to translation of the cutter, though some degree of lost motion is provided between the shuttle valve slider and the cutter.

摘要： A biopsy device includes a tissue sample holder and a cutter defining a cutter lumen. In one example, the tissue sample holder has a manifold, a plurality of chambers that are configured to separately hold tissue samples, and a cup configured to cover the manifold and chambers. The tissue sample holder is rotatable to successively align the chambers with the cutter lumen. A longitudinal passage extends along the manifold, and is positioned between two of the chambers. The manifold may be rotated to align the passage with the cutter lumen and with an opening in the cup. The passage of the manifold and the opening in the cup are configured to permit a portion of an instrument to be inserted through the opening and passage and into the cutter lumen. The instrument may be used to introduce one or more markers or medicine, etc., to a biopsy site.
