    摘要： A biopsy device comprises a body, a needle, and a cutter. A self-reversing cutter translation mechanism translates the cutter proximally and distally in response to rotation of the cutter in a single rotational direction. The cutter translation mechanism comprises a lead screw with discretely formed threads and a rotatable pawl. The cutter is translated proximally when the pawl is in a first rotational orientation; and distally when the pawl is in a second rotational orientation. Resilient members cause the pawl to be rotated between the first and second rotational orientations when the cutter reaches a distal position and a proximal position. A vacuum draws severed tissue samples through the interior of the cutter to deposit the samples in a holder. The translation mechanism engages a valve mechanism to provide simultaneous venting to part of the needle and reversal of the pawl orientation when the cutter reaches a distal position.

    摘要： A biopsy device comprises a probe assembly, a holster assembly, a tissue sample holder, and a manually operated rotation mechanism configured to rotate the tissue sample holder. The probe assembly comprises a cutter configured to sever a tissue sample. The tissue sample holder includes a plurality of tissue chambers configured to receive discrete severed tissue samples. The holster assembly comprises the non-motorized, manually operated rotation mechanism configured to allow a user to align consecutive chambers to successively collect discrete severed tissue samples. The tissue sample holder rotation mechanism may comprise a first button, a first lever, a first pawl, a first ratchet, an indexing shaft, and a first gear, which are all configured to, ultimately, rotate a tissue sample holder. The tissue sample holder rotation mechanism may alternately include thumbwheels, a worm gear, or a ratcheting lever, among other things.

    摘要： A tissue retrieval device comprises a tissue retrieval bag and resilient arms. The bag is releasably engaged with the resilient arms. One or two resilient arms expand the bag along a first plane to open the mouth of the bag. Another resilient arm expands the bag along a second plane to unfurl the bag. The first plane is substantially perpendicular to the second plane. The device further comprises a support tube having a passageway and a push/pull rod slidingly positioned within the passageway. The resilient arms are engaged with the push/pull rod such that the resilient arms and the push/pull rod travel uniformly relative to the longitudinal axis of the support tube. The arms collapse within the support tube and are resiliently biased to extend outwardly when the push/pull rod is translated distally relative to the support tube to expose the bag and arms.

    摘要： A tissue retrieval device includes an introducer tube and a tissue retrieval bag. The introducer tube is insertable into a patient through a trocar. The bag may be selectively exposed at the distal end of the introducer tube, receive a tissue specimen, and be withdrawn from the patient. The bag includes a plurality of folds allowing the bag to transition from a folded configuration to an unfolded configuration. The folds may extend along a length of the bag transverse to the introducer tube; or along a length of the bag parallel to the introducer tube. The folds may extend about a perimeter of the bag, such as a circumference of the bag, and may be spaced apart along a length of the bag transverse to the introducer tube. The folds may be formed by petals that provide the bag with a generally spherical configuration when the bag is unfolded.
