Abstract

A magnetic resonance imaging (MRI) compatible core biopsy system uses a biopsy device having intuitive graphical displays and a detachable remote keypad that advantageously allows convenient control even within the close confines afforded by a localization fixture installed within a breast coil that localizes a patient'"'"'s breast and guides a probe of the biopsy device relative to the localized breast. A control module for interactive control and power generation are remotely positioned and communicate and transmit rotational mechanical energy via sheathed cable.

Claims

1. A biopsy device comprising:

a. an outer cannula having a lateral tissue receiving aperture;

b. an inner tubular cutter disposed for translation within the cannula;

c. a sensor responsive to translation position of the inner tubular cutter; and

d. a handpiece comprising;

i. a graphical display operably configured to depict the translation position of the inner tubular cutter in response to the sensor,

ii. a integral receiving deck located near a proximal portion of the handpiece, and

iii. a keypad in communication with the handpiece, wherein the keypad is removably insertable into the receiving deck, wherein the keypad is operatively configured with a control unit to control translation of the inner tubular cutter when the keypad is removed from the receiving deck and when the keypad is inserted into the receiving deck.

2. The biopsy device of claim 1, wherein the graphical display comprises a bar graph annotated with longitudinal extents of the lateral tissue receiving aperture relative to indicated translation position of the inner tubular cutter.

3. The biopsy device of claim 1, further comprising a vacuum source communicating with the inner tubular cutter to prolapse tissue into the lateral tissue receiving aperture, the graphical display further operably configured to depict a mode of operation corresponding to the vacuum source.

4. The biopsy device of claim 3, further comprising a mode control and control circuitry responsive to user activation of the mode control to toggle between a plurality of modes of operation, the graphical display including a plurality of indicators illuminated to correspond to a current mode of operation.

5. The biopsy device of claim 4, further comprising a plurality of graphical depictions illustrating each of the plurality of modes of operation.

6. The biopsy device of claim 3, further comprising a lateral lumen attached to the outer cannula and communicating distally to the lateral tissue receiving aperture and proximally to atmosphere.

7. The biopsy device of claim 1, further comprising:

a probe assembly portion containing the inner tubular cutter, a cutter carriage attached to the inner tubular cutter, and a translation shaft engaged for longitudinal translation to the cutter carriage; and

a holster assembly including a rotation member engageable to the translation shaft.

8. The biopsy device of claim 7, wherein the probe assembly further comprises a cutter gear proximally attached to the inner tubular cutter, a rotation shaft having a spur gear portion positioned to engage the cutter gear to impart a rotation to the inner tubular cutter.

9. The biopsy device of claim 8, wherein the holster further comprises a fixed ratio transmission having one rotation output engageable to the translation shaft and another rotation output engageable to the rotation shaft.

10. The biopsy device of claim 9, further comprising a remotely positioned cutter translation motor coupled via a mechanical drive cable attached to the holster.

11. The biopsy device of claim 10, wherein the mechanical drive cable is attached to an undersurface of the holster to reduce torque loads at the outer cannula.

12. The biopsy device of claim 8, wherein spur gear portion is longitudinally dimensioned to disengage from the cutter gear when all of the inner tubular cutter is retracted proximally to the lateral tissue receiving aperture.

13. The biopsy device of claim 1, wherein the sensor comprises an encoder coupled to the inner tubular cutter.

16. The biopsy device of claim 1, wherein the receiving deck comprises at least one opening, wherein the keypad comprises at least one projection, wherein the projection of the keypad is operably configured to selectively engage the opening of the receiving deck.

17. The biopsy device of claim 16, wherein the receiving deck comprises a proximal opening and a distal opening, wherein the keypad comprises a proximal projection and a distal projection, wherein the proximal and distal projections of the keypad are operably configured to selectively engage the respective proximal and distal openings of the receiving deck.

14. A biopsy device comprising:

a. a probe assembly comprising;

i. an outer cannula having a lateral tissue receiving aperture,

ii. an inner tubular cutter disposed for translation within the cannula, and

iii. a sensor responsive to translation position of the inner tubular cutter; and

b. a handpiece in communication with the probe assembly, wherein the handpiece comprises a graphical display comprising;

i. a first indicator operably configured to depict a selected mode of a plurality of available modes for operating the biopsy device, and

ii. a second indicator operably configured to depict positioning of the inner tubular cutter relative to the lateral tissue receiving aperture for each selected mode of the plurality of available modes.

15. The biopsy device of claim 14, wherein the second indicator is formed by illuminating one or more of a plurality of discrete lights, wherein the plurality of discrete lights are in a linear arrangement, wherein the illumination of the one or more of the plurality of discrete lights is determined from the sensor responsive to translation position of the inner tubular cutter.
