Accordingly, it should be understood that lumen ( 562 ) of transfer tube ( 560 ) and lumen ( 503 ) of cutter drive member ( 502 ) together define a continuous path for tissue samples to flow through cutter drive member ( 502 ) and transfer tube ( 560 ) to tissue sample holder ( 300 ).
- tissue samples generally flow through cutter ( 130 ) into gate assembly ( 600 ) and then pass through cutter drive member ( 502 ) and transfer tube ( 560 ) before finally being deposited within tissue sample holder ( 300 ).
- both lumen ( 562 ) of transfer tube ( 560 ) and lumen ( 503 ) of cutter drive member ( 502 ) are in fluid communication with the interior of cutter ( 130 ).

- Sample inspection member ( 602 ) comprises an inspection portion ( 604 ) or window and a gate portion ( 610 ). Inspection portion is generally configured as an elongate tube with a lumen ( 606 ) extending axially through sample inspection member ( 602 ).
- Sample inspection member ( 602 ) of the present example is comprised of a substantially transparent material. Thus, it should be understood that the interior of lumen ( 606 ) is visible through inspection portion ( 604 ). As will be described in greater detail below, this transparent configuration permits an operator to visually inspect tissue samples as they are received and temporarily stored within inspection portion ( 604 ) of sample inspection member ( 602 ).
- inspection portion ( 604 ) of sample inspection member ( 602 ) is equipped with a sensor ( 605 ).
- Sensor ( 605 ) can comprises a variety of sensors such as impedance based sensors, light based sensors, doppler effect sensors, and/or etc.

- sensor ( 605 ) is generally in communication with lumen ( 606 ) to detect the presence of a tissue sample received within sample inspection member ( 602 ).
- sensor ( 605 ) can be further configured to detect certain characteristics of a tissue sample such as pathogens through impedance based detection mechanisms. In either case, data from sensor ( 605 ) can be used to change the operational state of biopsy device ( 10 ) when the presence of a tissue sample is detected within sample inspection member ( 602 ). For instance, in some examples control circuitry located within biopsy device ( 10 ), or associated with biopsy device ( 10 ), can stop or reduce the flow of vacuum through sample inspection member ( 602 ).
- sensor ( 605 ) of the present example is shown as being associated with inspection portion ( 604 ), it should be understood that in other examples sensor ( 605 ) can be associated with other components of biopsy device ( 10 ).
- inspection portion ( 604 ) generally rotates at various stages during operation.
- incorporating sensor ( 605 ) into inspection portion ( 604 ) could present some challenges with coupling sensor ( 605 ) to control module or other control features of biopsy device ( 10 ).
- sensor ( 605 ) can be placed in a variety of positions relative to inspection portion ( 604 ). For instance, in some examples sensor ( 605 ) can be positioned adjacent to inspection portion ( 604 ) within sample window ( 140 ). In other examples, sensor ( 605 ) can be positioned within outer housing ( 102 ) distally of inspection portion ( 604 ), but proximally of the interface between outer housing ( 102 ) and cannula ( 113 ) and needle ( 110 ).

It should therefore be understood that, during use, cutter drive member ( 502 ) is configured to communicate rotary motion to sample inspection member ( 602 ). This in turn communicates rotary motion to cutter ( 130 ).
- tapered wall ( 616 ) is positioned between inspection portion ( 604 ) and cylindrical wall ( 612 ).

As will be described in greater detail below, in some circumstances it may be desirable to manually rotate coupling collar ( 620 ) relative to sample inspection member ( 602 ). Thus, grip features ( 624 ) enhance the ability of an operator to rotate coupling collar ( 620 ) relative to sample inspection member ( 602 ).
- grip features ( 624 ) are shown as a series of elongate slots, it should be understood that in other examples any other grip feature can be used as will be apparent to those of ordinary skill in the art in view of the teachings herein.

- Vacuum openings ( 632 ) are configured to permit vacuum to pass through gate seal ( 630 ) generally unencumbered, even when a tissue sample is positioned adjacently relative to gate seal ( 630 ).
- gate seal ( 630 ) may also include protrusions or other structural features to maintain some separation between gate seal ( 630 ) and any adjacent tissue sample.
- Gate slit ( 634 ) comprises a slit extending through gate seal ( 630 ) from one vacuum opening ( 632 ) to another on an opposite side of gate seal ( 630 ).
- slit ( 634 ) is represented as essentially a line in FIG. 8 , it should be understood that gate seal ( 630 ) is generally separable at gate slit ( 634 ) to transition from a closed position (shown in FIG. 8 ) to an open position.
- gate seal is generally comprised of a flexible elastomeric material such as rubber, silicon, latex, or etc.

- Gate portion ( 504 ) is best seen in FIG. 10 .
- gate portion ( 504 ) of cutter drive member ( 502 ) is generally configured to abut inner flange ( 619 ) of sample inspection member ( 602 ) to hold gate seal ( 630 ) in position between cutter drive member ( 502 ) and sample inspection member ( 602 ).
- the exterior of gate portion ( 504 ) comprises a retaining channel ( 506 ), a proximal flange ( 507 ), and a locating protrusion ( 508 ).
- Retaining channel ( 506 ) is configured to receive an o-ring or other sealing feature to substantially seal the interface between cutter drive member ( 502 ) and sample inspection member ( 602 ).
- Proximal flange ( 507 ) is formed by a differential between the outer diameter of gate portion ( 504 ) and drive portion ( 520 ) of cutter drive member ( 502 ).

- the interior of gate portion ( 504 ) of cutter drive member ( 502 ) comprises a plurality of vacuum channels ( 510 ) disposed between a plurality of stop members ( 512 ). Both vacuum channels ( 510 ) and stop members ( 512 ) are disposed angularly around lumen ( 503 ) of cutter drive member ( 502 ). Vacuum channels ( 510 ) are configured to align with corresponding vacuum channels ( 618 ) in gate portion ( 610 ) of sample inspection member ( 602 ).
- gate seal ( 630 ) when gate seal ( 630 ) is disposed between gate portion ( 504 ) of cutter drive member ( 502 ) and gate portion ( 610 ) of sample inspection member ( 602 ), respective vacuum channels ( 510 , 618 ) permit vacuum to flow through vacuum openings ( 632 ) of gate seal ( 630 ). This configuration permits the flow of vacuum through gate seal ( 630 ) even when a tissue sample is positioned adjacent to gate seal ( 630 ).
- Stop members ( 512 ) generally define a common distal face ( 514 ) of gate portion ( 504 ). As will be described in greater detail below, this common distal face ( 514 ) is configured to prevent gate seal ( 630 ) from opening proximally into gate portion ( 504 ) of cutter drive member ( 502 ). Instead, as will also be described in greater detail below, gate seal ( 630 ) is configured to open into gate portion ( 610 ) of sample inspection member ( 602 ).
- Stop members ( 512 ) also define an inner diameter that generally corresponds to the outer diameter of transfer tube ( 560 ) of cutter actuation assembly ( 500 ).
- transfer tube ( 560 ) generally remains stationary as cutter drive member ( 502 ) rotates and translates within probe ( 100 ).
- transfer tube ( 560 ) is configured to pass through the common distal face ( 514 ) defined by stop members ( 512 ). As will be described in greater detail below, this configuration permits transfer tube ( 560 ) to transition gate seal ( 630 ) to the open position described above.
- FIG. 11 shows cutter drive member ( 502 ) coupled to sample inspection member ( 602 ) by coupling collar ( 620 ).
- coupling collar ( 620 ) surrounds at least a portion of the exterior of both gate portions ( 504 , 610 ) of cutter drive member ( 502 ) and sample inspection member ( 602 ), respectively.
- Gate portion ( 504 ) of cutter drive member ( 502 ) is disposed within outer cylindrical wall ( 612 ) of sample inspection member ( 602 ), with locating protrusion ( 508 ) of cutter drive member ( 502 ) disposed within locating feature ( 613 ) of sample inspection member ( 602 ).
- Collar ( 629 ) of coupling collar ( 620 ) engages proximal flange ( 507 ) of cutter drive member ( 502 ).
- threads ( 614 ) of sample inspection member ( 602 ) engage threads ( 628 ) of coupling collar ( 620 ).
- collar ( 629 ) of coupling collar ( 620 ) pulls gate portion ( 504 ) of cutter drive member ( 502 ) toward gate portion ( 610 ) of sample inspection member ( 602 ). This in turn holds cutter drive member ( 502 ) in the position shown in FIG. 11 .
- gate seal ( 630 ) is disposed between inner flange ( 619 ) of sample inspection member ( 602 ) and common distal face of cutter drive member ( 502 ) when sample inspection member ( 602 ) is coupled to cutter drive member ( 502 ). In this position, vacuum channels ( 510 ) of cutter drive member ( 502 ) and vacuum channels ( 618 ) of sample inspection member ( 602 ) are aligned with vacuum openings ( 632 ) of gate seal ( 630 ).
- vacuum is free to pass from lumen ( 503 ) of cutter drive member ( 502 ) through vacuum openings ( 632 ) of gate seal ( 630 ), through vacuum channels ( 618 ) of sample inspection member ( 602 ) and into lumen ( 606 ) of sample inspection member ( 602 ).
- this configuration prevents a pressure differential from forming on either side of gate seal ( 630 ).
- FIGS. 12-18 show an exemplary use of cutter actuation assembly ( 500 ) and gate assembly ( 600 ) to view a tissue sample through sample window ( 140 ) of probe ( 100 ).
- biopsy device ( 10 ) begins with cutter ( 130 ) advanced relative to lateral aperture ( 114 ) to a distal position such that lateral aperture ( 114 ) is in a closed configuration as shown in FIG. 12 .
- lateral aperture ( 114 ) With lateral aperture ( 114 ) in the closed configuration, an operator can insert needle ( 110 ) into the breast of a patient. Insertion of needle ( 110 ) can be performed under any one or more of the image guidance modalities described above such as ultrasound, stereotactic x-ray, or MRI.
- cutter actuation assembly ( 500 ) when cutter ( 130 ) is positioned in the distal position, cutter actuation assembly ( 500 ) is in a corresponding distal position.
- cutter drive member ( 502 ) When cutter actuation assembly ( 500 ) is in the distal position, cutter drive member ( 502 ) is positioned distally relative to translation member ( 530 ), drive gear ( 540 ), and transfer tube ( 560 ).
- translation member ( 530 ), drive gear ( 540 ), and transfer tube ( 560 ) all remain in a stationary axial position as cutter drive member ( 502 ) is moved axially to translate cutter ( 130 ).
- translation member ( 530 ), drive gear ( 540 ), and transfer tube ( 560 ) will remain in the position shown in FIG. 13 as cutter ( 130 ) is translated relative to lateral aperture ( 114 ) of needle ( 110 ).
- biopsy device ( 10 ) is configured to receive an operator input via buttons, foot pedals, and/or other features to initiate the sampling sequence.
- holster ( 200 ) will begin to rotate drive gear ( 540 ) in a counter clockwise direction as shown in FIG. 15 . Keys ( 546 ) of drive gear ( 540 ) engage longitudinal channels ( 528 ) of cutter drive member ( 502 ) to initiate rotation of cutter drive member ( 502 ) in the counter-clockwise direction.
- translation member ( 530 ) is responsive to counter-clockwise rotation of cutter drive member ( 502 ) to provide proximal axial translation of cutter drive member ( 502 ) via engagement between threaded portion ( 522 ) and threads ( 536 ) of translation member ( 530 ).
- Axial translation and rotation of cutter drive member ( 502 ) is then transferred to gate assembly ( 600 ) by the coupling between sample inspection member ( 602 ) and cutter drive member ( 502 ) via coupling collar ( 620 ). Because cutter ( 130 ) is fixedly secured to sample inspection member ( 602 ), rotation and translation transferred to sample inspection member ( 602 ) is also transferred to cutter ( 130 ). Accordingly, as cutter drive member ( 502 ) is translated and rotated via drive gear ( 540 ) and translation member ( 530 ), cutter ( 130 ) is correspondingly rotated and translated as shown in FIG. 14 .
- cutter drive member ( 502 ) Rotation and translation of cutter ( 130 ) via cutter drive member ( 502 ) continues until cutter ( 130 ) is positioned at a proximal position as shown in FIG. 16 .
- cutter drive member ( 502 ) When cutter ( 130 ) is in the proximal position, cutter drive member ( 502 ) is correspondingly in a proximal position shown in FIG. 17 .
- cutter drive member ( 502 ) is positioned within probe ( 100 ) such that translation member ( 530 ) and drive gear ( 540 ) are positioned proximally relative to threaded portion ( 522 ) of cutter drive member ( 502 ).
- holster ( 200 ) ceases rotation of drive gear ( 540 ), which correspondingly ceases rotation and translation of cutter drive member ( 502 ).
- transfer tube ( 560 ) of cutter drive assembly ( 500 ) generally remains stationary relative to cutter drive member ( 502 ). As best seen in FIG. 18 , this configuration results in transfer tube ( 560 ) extending through gate seal ( 630 ) and into lumen ( 606 ) of sample inspection member ( 602 ). Because transfer tube ( 560 ) extends through gate seal ( 630 ), it should be understood that transfer tube ( 560 ) engages gate slit ( 634 ) to open gate slit ( 634 ) around the exterior of transfer tube ( 560 ).
- gate seal ( 630 ) is in an open position.
- cutter ( 130 ) is positioned in the proximal position such that lateral aperture ( 114 ) is in an open position.
- gate seal ( 630 ) there is a relationship between gate seal ( 630 ) and lateral aperture ( 114 ) such that when lateral aperture ( 114 ) is in the open position, gate seal ( 630 ) is correspondingly in the open position.
- gate seal ( 630 ) is in a corresponding closed position as shown in FIG. 11 .
- needle ( 110 ) is configured so that tissue may be prolapsed within lateral aperture ( 114 ).
- vacuum is applied to cutter ( 130 ).
- vacuum is supplied to cutter ( 130 ) via tissue sample holder ( 300 ).
- vacuum is communicated to tissue sample holder ( 300 ), which is communicated through transfer tube ( 560 ), into lumen ( 606 ) of sample inspection member ( 602 ) and into cutter ( 130 ). Vacuum then pulls tissue through lateral aperture ( 114 ).
- vacuum is also applied to lumen ( 120 ) of cannula ( 113 ) via manifold ( 116 ) to assist with prolapsing tissue.
- vacuum applied to lumen ( 120 ) of cannula ( 113 ) via manifold ( 116 ) is entirely optional and in some examples vacuum is supplied exclusively through cutter ( 130 ).
- a tissue sample can be severed via sharp distal edge ( 132 ) of cutter ( 130 ) by driving cutter ( 130 ) distally.
- holster ( 200 ) rotates drive gear ( 540 ) in a clockwise direction to initiate the same sequence described above with respect to FIGS. 12-17 , but in an opposite direction.
- cutter drive member ( 502 ) is driven distally by cutter drive member ( 502 )
- cutter drive member ( 502 ) and sample inspection member ( 602 ) both move distally such that transfer tube ( 560 ) disengages gate seal ( 630 ). This causes gate seal ( 630 ) to return to the closed position shown in FIG. 11 .
- tissue sample holder ( 300 ) With a tissue sample severed by distal translation of cutter ( 130 ), the severed tissue sample can next be transported proximally through cutter ( 130 ) and into sample inspection member ( 602 ).
- vacuum is applied to tissue sample holder ( 300 ), which flows into lumen ( 503 ) of cutter drive member ( 502 ) via transfer tube ( 560 ). Vacuum then flows through cutter drive member ( 502 ) and into lumen ( 606 ) of sample inspection member ( 602 ) via vacuum channels ( 510 , 618 ) of cutter drive member ( 502 ) and sample inspection member ( 602 ) via vacuum openings ( 632 ) of gate seal ( 630 ). Finally, vacuum flows from lumen ( 606 ) of sample inspection member ( 602 ) and into cutter ( 130 ) to transport the severed tissue sample through cutter ( 130 ) and into sample inspection member ( 602 ).
- sample inspection member ( 602 ) Once the severed tissue sample is transported into sample inspection member ( 602 ), the severed tissue sample is prevented from traveling further by gate seal ( 630 ), which is in the closed position. With the severed tissue sample positioned within sample inspection member ( 602 ), an operator can visually inspect the severed tissue sample with the naked eye due to the transparency of sample inspection member ( 602 ), which is visible through sample window ( 140 ) of probe ( 100 ). In some instances, coupling collar ( 620 ) may also be used by an operator to manually rotate sample inspection member ( 602 ) to provide a 360° view of the severed tissue sample.
- the severed tissue sample can be transported to tissue sample holder ( 300 ).
- the severed tissue sample can be transported to tissue sample holder ( 300 ) by returning cutter ( 130 ), sample inspection member ( 602 ), and cutter drive member ( 502 ) to the proximal position shown in FIGS. 16-18 .
- this causes sample inspection member ( 602 ) and cutter drive member ( 502 ) to translate relative to transport tube ( 560 ) to position transfer tube ( 560 ) through gate slit ( 634 ) in gate seal ( 630 ) so that gate seal ( 630 ) is in the open position.
- the severed tissue sample can be freely transported into transfer tube ( 560 ), through gate seal ( 630 ), and into tissue sample holder ( 300 ).
- cutter ( 130 ) is also positioned in the proximal position so that lateral aperture ( 114 ) is in the open position. Accordingly, transporting the severed tissue sample to tissue sample holder ( 300 ) also prepares needle ( 110 ) for receipt of another tissue sample holder.
- tissue sample holder ( 300 ) With the severed tissue sample received in tissue sample holder ( 300 ) an operator can next proceed by collecting one or more additional samples using the process described above with respect to the severed tissue sample. After collecting any suitable number of tissue samples, an operator may finalize the procedure by removing needle ( 110 ) from the patient, optionally marking the biopsy site, and sealing the opening in the patient. Any number of tissue samples collected during the biopsy procedure can finally be removed from tissue sample holder ( 300 ) and subjected to any desired tissue sample analysis procedure.

- the interior of bore ( 834 ) includes a threading ( 836 ) that is configured to engage threaded portion ( 822 ) of cutter drive member ( 802 ).
- engagement between threading ( 836 ) of translation member ( 830 ) and threaded portion ( 822 ) of cutter drive member ( 802 ) is generally configured to cause translation of cutter drive member ( 802 ) in response to rotation of cutter drive member ( 802 ).
- threading ( 836 ) is shown as including only a single turn of threading such that threading ( 836 ) may be characterized as only having a single thread. In some contexts, this configuration may be desirable to more readily manufacture translation member ( 830 ) using injection molding based manufacturing operations. However, it should be understood that in other examples threading ( 836 ) can include multiple threads extending along the entire, or a portion of, the axial length of translation member ( 830 ).
- Translation member ( 830 ) further comprises a pair of key features ( 838 ) extending upwardly and downwardly from body ( 832 ), as best seen in FIG. 22 .
