CROSS REFERENCE TO RELATED APPLICATIONS This application is a continuation of the commonly-owned U.S. patent application Ser. No. 11/344,879 �BIOPSY DEVICE WITH REPLACEABLE PROBE INCORPORATING STATIC VACUUM SOURCE DUAL VALVE SAMPLE STACKING RETRIEVAL AND SALINE FLUSH� to Hibner, filed 1 Feb. 2006 now U.S. Pat. No. 7,662,109, the disclosure of which is hereby incorporated by reference in its entirety.
This application is also a continuation-in-part of the co-pending and commonly-owned U.S. patent application Ser. No. 11/198,558 �BIOPSY DEVICE WITH REPLACEABLE PROBE AND INCORPORATING VIBRATION INSERTION ASSIST AND STATIC VACUUM SOURCE SAMPLE STACKING RETRIEVAL� to Hibner et al., filed 5 Aug. 2005, the disclosure of which is hereby incorporated by reference in its entirety.
FIELD OF THE INVENTION The present invention relates in general to biopsy devices, and more particularly to biopsy devices having a cutter for severing tissue, and even more particularly to biopsy devices for multiple sampling with a probe remaining inserted.
With a long probe, the rate of sample taking is limited not only by the time required to rotate or reposition the probe but also by the time needed to translate the cutter. As an alternative to this �long stroke� biopsy device, a �short stroke� biopsy device is described in the following commonly assigned patent applications: U.S. patent application Ser. No. 10/676,944, �Biopsy Instrument with Internal Specimen Collection Mechanism� filed Sep. 30, 2003 in the name of Hibner et al.; and U.S. patent application Ser. No. 10/732,843, �Biopsy Device with Sample Tube� filed Dec. 10, 2003 in the name of Cicenas et al. The cutter is cycled across the side aperture, reducing the sample time. Several alternative specimen collection mechanisms are described that draw samples through the cutter tube, all of which allow for taking multiple samples without removing the probe from the breast.
SUMMARY OF THE INVENTION The present invention addresses these and other problems of the prior art by providing a biopsy device that has a needle with a probe tube defining a cutter lumen, a sample aperture formed in the probe tube, a barrier defining a first fluid passage and a second fluid passage that both distally terminate at the sample aperture. A motorized mechanism axially translates a cutter tube within the probe tube across the sample aperture to sever tissue prolapsed therein to axially translate the cutter tube. One of the first and second fluid passages is defined within the cutter tube and the other is defined between an outer surface of the cutter tube and an inner surface of the probe tube. Advantageously, a flush valve assembly responds to a flush control and to the distally positioned cutter tube to couple either the first or second fluid passage to a fluid supply while the other is at a lower pressure so that the needle is flushed. Thereby, tissue debris or coagulated blood may be flushed so that repeated tissue samples may be taken without impediment. However, the saline flush is selectively employed at the user's discretion, providing an economical reduction in the usage of saline and a corresponding reduction in the overall size of the fluid collection reservoir. It is also believed that certain pathology analyses would benefit from not subjecting tissue samples to a saline flush.
DETAILED DESCRIPTION OF THE INVENTION In FIGS. 1-2, a biopsy device 10 has a reusable hand piece 12 and a disposable probe 14 that enables economical taking of multiple percutaneous core biopsy samples by accessing a standard medical vacuum pump or wall-mounted vacuum access port (not shown) through an interfacing vacuum conduit 16. In addition, the biopsy device 10 advantageously incorporates a saline flush capability received from saline supply conduit 17. In the illustrative version, the reusable hand piece 12 is self-powered and suitable for use in conjunction with ultrasonic diagnostic imaging. The disposable probe 14 reduces the portion of biopsy device 10 that requires protective packaging to avoid contact with sharp surfaces and to keep it sterile prior to use. Further economy is accomplished by reducing the portion of the biopsy device 10 that is disposed as medical waste between uses. Movable components of the disposable probe 14 are advantageously locked until mounted in an access trough 18 formed in a handle housing 20 of the reusable hand piece 12. It should be appreciated that one or more standard mechanical, pneumatic, or electrical latches (not shown) may be integrated into the biopsy device 10 to secure the disposable probe 14 to the reusable hand piece 12.
In FIGS. 1-4, the disposable probe assembly 14 includes a substantially rectangular cover 22 sized to close the access trough recess 18 (FIGS. 1-2). An end slot 24 formed in the cover 20 (FIGS. 1-2, 5-6) is closed by a probe union sleeve 26 attached to an inner surface 27 (FIG. 1) of the substantially rectangular cover 22. A core biopsy needle (�probe�) assembly 28 passes longitudinally through the probe union sleeve 26 and is formed by a probe tube 30 that includes an underlying lateral (vacuum) lumen 32 that communicates with a side aperture 34 (FIG. 1) via holes 35 (FIG. 4) near a distal opening 36 of the probe tube 30 that is closed by a piercing tip 38. A cutter tube 40 is sized to closely fit and translate within an inner diameter (i.e., cutter lumen) of the probe tube 30 with a length sufficient to close the side aperture 34 with a proximal end 42 extending from the probe union sleeve 26 to attach to a cutter gear 44, as depicted in FIG. 1.
It should be appreciated that the probe tube defines first and second fluid passages that are separated longitudinally within the probe tube and distally communicate with each other at the side aperture 34. In the illustrative version, the first fluid passage is defined within the cutter tube 40 and the second fluid passage is defined within the lateral lumen 32 that is �hard walled� apart from a cylindrical portion of the cutter lumen of the probe tube 35. However, for a cylindrical probe tube (not shown), a cutter tube may be axially offset within the cutter lumen of the probe tube such that the cutter tube may separate the first and second fluid passages, especially if the cutter tube need not be retracted for retraction of samples (e.g., vacuum retraction, straw retraction, single sample per insertion devices).
With the biopsy device 10 assembled, the reusable handpiece 12 is manipulated to insert the piercing tip 38 of the core biopsy needle (probe) assembly 28 into tissue. Penetration of dense tissue is assisted by moving the slide button 168 distally to a �tissue insertion mode� wherein the slide spur gear 176 engages the tissue penetration gear 190. Depression of the forward motor rotation key 162 turns these gears 176, 190 causing the circular cam wheel 216 to turn against strike pin 214 that creates proximal longitudinal motion of frame 204 and the attached core biopsy needle (probe) assembly 28 of approximately 0.1 inch at a rotation rate of 7 cycles per second (FIG. 12). Left and right compression springs 226, 228 provide the restoring distal longitudinal motion to frame 204 and probe assembly 28 as left and right compression springs 226, 228 are repeatedly compressed between the distal surface of the left and right spring cavities 218, 220 of the frame 204 and the left and right tabs 222, 224 of the housing 20. The restoring distal longitudinal motion to frame 204 and core biopsy needle (probe) assembly 28 result in a corresponding distal motion of piecing tip 38 that assists in penetrating tissue.
By virtue of the foregoing, with one-handed operation, a clinician is able to select between a plurality of ports (e.g., vacuum pressure, atmospheric pressure, saline supply) that can communicate with a side aperture 34 of a needle assembly 28 of core biopsy device 10. In particular, valve mechanisms are contained on the hand piece that need only selectively port a constant vacuum source without the necessity for a separate, expensive programmed control module. One advantage of such an economical capability is providing �on-demand� saline flush to the side aperture 34 (or distal opening) of the needle assembly 28. During normal tissue sampling, the side aperture 34 pressure levels transitions from vacuum during cutting to atmospheric pressure while the tissue sample is being transported proximally out of the reusable handpiece 12. Clearing tissue debris from the needle assembly 28 at the press of a saline push key 166 during the sample ensures proper operation so that the desired number of samples may be taken.
