摘要: A surgical instrument includes a handle portion, a shaft housing a firing bar, an end effector comprising an anvil, a lower jaw, and a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft. The lower jaw is configured to receive a removable cartridge. The cartridge includes a housing, a plurality of staples disposed in the housing, and a deck disposed over the plurality of staples. The deck defines apertures, with each aperture being substantially disposed over each staple. The instrument includes an anvil cartridge removably received in an anvil frame. The anvil cartridge is severed by the firing bar when the firing bar is advanced through tissue such that material from the anvil cartridge is released onto the severed tissue.

摘要: A biopsy system comprises an introducer, a biopsy device having a needle, and a marker applier. The introducer may include a closed distal tip, a lateral aperture, a proximally facing interior wall, and a ramp that guides the closed distal end of a marker applier up and into abutment with the wall as the applier is fed into the introducer. The needle of the biopsy device includes a blunt distal end and features providing clearance for the ramp as the blunt distal end is brought into abutment with the wall when the needle is fed into the introducer. The introducer may alternatively include an open distal end having resiliently biased leaves that bear against an inserted biopsy device needle. In some other versions, a fin projects laterally from the closed distal end of a marker applier, spacing the distal end away from a sidewall region of the introducer cannula.

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 probe that is configured to couple with a holster. The probe comprises a needle, a cutter, and a body portion. The needle is rotatable and translatable relative to the body portion. The holster has a locking feature that is configured to prevent the needle from rotating relative to the body portion upon coupling of the probe with the holster. The locking feature may also be configured to prevent the needle from translating relative to the body portion upon coupling of the probe with the holster. The same probe may thus be used with a holster intended for use in a fixture-based, stereotactic setting, in which rotation and translation of the needle may be desired; and with a holster intended for use in a handheld, ultrasound-guided setting, in which rotation and translation of the needle may be less desired if not undesirable.

摘要: A biopsy site marker delivery device includes a relatively flexible marker deployer tube having a closed distal end, a push rod slidably disposed within the tube, and at least one marker disposed in the tube. The deployer tube includes a side exit port with an adjacent ramp for transversely dispensing the marker upon distal advancement of the push rod within the tube. An elongate member such as a sleeve is operable to guide and/or stabilize the flexible deployer tube as the tip of the tube is inserted into an access channel such as a channel provided by a cannula or biopsy device. An internal package member is configured to support the marker delivery device and the elongate member, with the elongate member being positioned over the side exit port to prevent the marker from inadvertently exiting the side exit port. The package member may reside in a sterile packaging envelope

摘要: A biopsy device includes a body portion, a cannula, a cutter, and a tissue stop having a proximal face. The cannula has a transverse aperture that is defined in part by a proximal edge and a distal edge. The cutter is movable to a distal position to sever tissue protruding through the transverse aperture. A tip at the distal end of the cannula has a sharp edge that extends proximally to a longitudinal position that is proximal to the longitudinal position of the distal edge of the transverse aperture. The sharp edge of the tip extends to a longitudinal position that is proximal to the longitudinal position of the distal cutting edge of the cutter when the cutter is at the distal position. The sharp edge of the tip extends to a longitudinal position that is proximal to the longitudinal position of the proximal face of the tissue stop.

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.
