Abstract

A surgical biopsy system is provided for removing at least one tissue sample from a surgical patient. The surgical biopsy system comprises an elongated, hollow piercer and a cutter rotatably and axially positionable relative to the piercer. The piercer has a lateral port for receiving the tissue sample into the piercer. The surgical biopsy system further comprises a power transmission source operatively connected to the cutter for rotating and translating the cutter, a control unit, and a display mounted in a display frame for showing an operator a plurality of operational modes of the surgical biopsy system. The surgical biopsy system further comprises at least one control button operatively connected to the control unit by a circuit and remotely located from the control unit. The operator may actuate the control button(s) to select any one of the operational modes and the selected operational mode is visually identifiable on the display.

Claims

1. A biopsy system comprising:

a) a handpiece including an elongated, hollow piercer and a cutter rotatably and axially positionable relative to said piercer, said piercer having a lateral port for receiving a tissue sample into said piercer, and said handpiece being operably associated with a vacuum source;

b) a control unit operatively associated with said handpiece for selecting from two or more operational modes, wherein at least two of said operational modes provide control of vacuum in said biopsy system, wherein each of the two or more operational modes comprises a series of preprogrammed actions;

c) a console assembly, wherein the control unit is operatively associated with the console assembly; and

d) a remote control, wherein the remote control is operable to be selectively coupled with the control unit to place the remote control in communication with the control unit; and

wherein at least one of the operational modes includes a sampling mode wherein the cutter is operable to advance with respect to the lateral port to sever a tissue sample received in the port, and wherein the sampling mode provides for retraction of the cutter with respect to the lateral port after a predetermined period of time.

2. The biopsy system of claim 1 comprising an indicator representative of at least one of said two or more operational modes providing control of vacuum in said biopsy system.

3. The biopsy system of claim 2 wherein said indicator is visual.

4. The biopsy system of claim 1 wherein said control unit is adapted to provide a first sampling method and a second sampling method.

5. The biopsy system of claim 1 wherein said control unit is adapted to provide a non-sampling mode wherein vacuum is provided to a portion of said handpiece.

6. The biopsy system of claim 5 wherein said non-sampling mode comprises a mode for clearing a portion of the handpiece.

7. The biopsy system of claim 1 comprising at least one control button disposed on said handpiece to select an operational mode of the biopsy system.

8. The biopsy system of claim 1 wherein the handpiece is coupled with the console assembly via an elongate member.

9. The biopsy system of claim 1 further comprising one or more displays in communication with the control unit.

10. The biopsy system of claim 9 wherein at least one of the one or more displays is coupled with the console assembly.

11. The biopsy system of claim 10 wherein a first display of the one or more displays is secured to the console assembly, and wherein a second display of the one or more displays is remotely coupled with the console assembly.

12. The biopsy system of claim 1 wherein the control unit comprises a device identifier module, wherein the device identifier module is configured to detect whether the remote control is in communication with the control unit.

13. The biopsy system of claim 12 wherein the device identifier module is configured to transmit a signal in response to detecting that the remote control is in communication with the control unit.

14. The biopsy system of claim 13 wherein the handpiece further comprises a controller, wherein the controller is selectively operable to communicate with the control unit, wherein the signal transmitted by the device identifier module is operable to render the controller inoperable.

15. A biopsy system comprising:

a) a handpiece including an elongated, hollow piercer and a cutter rotatably and axially positionable relative to said piercer, said piercer having a lateral port for receiving a tissue sample into said piercer, and said handpiece being operably associated with a vacuum source;

b) a control unit operatively associated with said handpiece for selecting from two or more operational modes, wherein at least one operational mode provides vacuum during a sampling operation, wherein at least one operational mode provides pulsed vacuum during a non-sampling operation, wherein each of the two or more operational modes comprises at least one preprogrammed operation.

16. The biopsy system of claim 15 wherein the control unit is operable for providing at least three operational modes.

17. The biopsy system of claim 15 wherein the control unit is operable for providing at least two different sampling modes.

18. The biopsy system of claim 15 wherein the control unit is operable for providing a cutter positioning mode, a sampling mode, and a mode for clearing the piercer.

19. The biopsy system of claim 15 wherein the control unit is operable for clearing the piercer according to at least two predetermined sequences of cutter position.

20. A biopsy system comprising:

a) a handpiece including an elongated, hollow piercer and a cutter rotatably and axially positionable relative to said piercer, said piercer having a lateral port for receiving a tissue sample into said piercer, and said handpiece being operably associated with a vacuum source;

b) a control unit operatively associated with said handpiece for selecting from two or more operational modes once the control unit is powered on, and wherein at least two of said operational modes provide control of vacuum in said biopsy system;

c) at least one display in communication with the control unit; and

d) a remote control, wherein the remote control is operable to be selectively coupled with the control unit to place the remote control in communication with the control unit.

21. The biopsy system of claim 20 further comprising a console assembly, wherein the at least one display is coupled with the console assembly.

22. The biopsy system of claim 21 comprising a first display secured to the console assembly, and a second display remotely coupled with the console assembly.

23. The biopsy system of claim 20 wherein the at least one display is associated with at least one icon.

24. The biopsy system of claim 20 wherein the at least one display is associated with a touch screen.

25. The biopsy system of claim 20 wherein the at least one display is associated with an LCD controller.

26. A biopsy system comprising:

a handpiece including an elongated, hollow piercer and a cutter rotatably and axially positionable relative to said piercer, said piercer having a lateral port for receiving a tissue sample into said piercer, and said handpiece being operably associated with a vacuum source; and

a control unit operatively associated with said handpiece for selecting from two or more operational modes once the control unit is powered on, wherein at least one operational mode provides pulsed vacuum to at least one of the cutter and the piercer.
