  • [0023]
    FIG. 6 is a general block diagram of the biopsy system 10 shown in FIG. 1 which has a tissue removal system 11, an ultrasonic imaging system 12 and a main computer module 30 and an image display screen. The tissue removal system 11 of system 10 has a tissue removal control module 31, a vacuum module 32 for vacuum operations and tissue removal connector module 33 probe connectors 21 and 22. The vacuum module 32 has a vacuum line, a valve operated by the tissue removal control module 31 and a vacuum source (e.g. a connection to a vacuum line or a vacuum pump) which are not shown. The imaging system 12 has an ultrasound control module 34 for ultrasonic emission and reception and an interface with the main computer module 30. An ultrasound connector module 35 is in communication with the ultrasound control module and has ultrasound probe connectors 23, 24 and 25. Output from the main computer module 30 related to the imaging input data thereto from the ultrasound control module is directed through a communication link to the image display screen 13 to display ultrasonic diagnostic images from an ultrasonic probe (not shown) connected to one of the ultrasound probe connectors 23, 24 or 25.
  • [0024]
    The input console 14 is connected via a communication link to the main computer module 30 which in turn has communication links to the tissue removal control module 31 and the ultrasound control module 34. This allows the single input console 14 to be employed to control both the tissue removal system 11 and the imaging system 12. The main display screen 13 is positioned right above the input console 14 so that a single operator may easily operate both the tissue removal system 11 and the ultrasound imaging system 12 from a single console. Further details of the tissue removal system can be found in patents and published applications of SenoRx, Inc. previously referred to and incorporated herein.
  • [0025]
    The ultrasound imaging system 12 for producing ultrasound images has ultrasound control module 34 is coupled to a ultrasound connector module 35 has probe connectors 23, 24 and 24 to which may be connected an ultrasound probe (not shown) The probe generates and receives acoustic signals. The acoustic signals that are generated by the probe are directed towards a body region of a patient, e.g. breast, and some of the acoustic signals are reflected back to the probe as echo signals. The echo signals obtained by the probe are sent back to the ultrasound control module 34 which processes the echo signals to extract data that is sent to the main computer module 30. The main computer module 30 performs a display data processing in real-time which is sent to the ultrasound display screen 13 where an ultrasound diagnostic image is displayed. See U.S. Pat. No. 6,325,759, for example, which is incorporated herein by reference. Input console 14 allows the user to interact with the main computer module and modify the ultrasound configuration. Further details of the ultrasound imaging system can be found in the patents and published applications of Ultrasonix previously referred to and incorporated herein.
  • [0026]
    In the embodiment shown in FIG. 6, only the vacuum control module 32 and the tissue removal control modules 32 are shown. However, additional modules may be provided, for example modules for a temperature probe, a heart rate monitor device, a drug infusion tools, anesthesia tools, or other surgical or medical devices that may operate with the biopsy system 10. They may be connected to the tissue removal control module 31 or directly to the main computer module 30. The tissue removal devices connected to the tissue removal connector module 33 may have mechanical tissue cutting members or radio frequency (RF) powered electrosurgical cutting members for performing the surgery. It is to be understood that other peripheral modules can be of different forms and functions, and they may not be required to be physically connected to the tissue removal control module 31 or the ultrasound control module 34 or directly to the main computer module 30 so as to communicate therewith.
  • [0027]
    The tissue removal control module 31 is a microprocessor-based electrical device with built-in software functions necessary to operate various handheld devices for both tissue removal. Each handheld device preferably contains a software script, stored in a memory device within the handheld device, for operating that particular device when connected to the tissue removal control module. For example, the said software script may be stored in non-volatile memories such as erasable programmable read only memories (EPROMs), electrically erasable programmable read only memories (EEPROMs) or flash memories. When a handheld device is indirectly connected to the tissue removal control module 31, the software script within the handheld device will be downloaded into the tissue removal control module. This software script will enable the tissue removal control module 31 to control the functionalities of a particular handheld device. Connection to the main computer module 30 allows the touch screen 14 to display its pertinent information and allow control input through either the touch screen or the keyboard 15. During the operation of a handheld device, a graphical user interface (GUI) software will display information on the touch screen 14 relevant to the operation of the tissue removal control module 31 and the handheld device to the operator. It is understood by those skilled in the art that the information displayed may vary depending upon the type of handheld device connected, the operational state of the handheld device as well as other environmental factors affecting the operation of both the handheld device and the main computer module 30.
  • [0028]
    It is understood that although the various modules and the handheld devices for either the tissue removal system 11 or the ultrasound image system 12 may be interconnected through wired connections (including connector modules and wires) for their operations, the communication links can be easily implemented through wireless communications. However, the conventional wired connections have certain advantages such as low signal interferences, but the wireless technology can turn the operation of the handheld device to a more mobile operation, which benefits the operator as well. For example, almost all the control signals can be sent through a predetermined wireless communication channel using technologies such as Bluetooth or 802.11 compliant wireless technologies. When the handheld device is battery powered, then the operation may be completely mobile. It is also practical that the wired communication channels may be used together with the wireless communication channels so that the tissue removal control module can take advantage of the available wireless technologies for providing convenience to the operator, while still benefiting from using some conventional wired technologies. In short, while the examples provided herein illustrate embodiments having features of the invention, it should be understood that communications between devices can take various forms and the main computer module 30, the tissue removal control module 31 and the ultrasound control module 33 are designed to use the most practical technologies for fulfilling the need of the operators.
  • [0029]
    The biopsy system may be powered by a single power source (not shown) or can have multiple power sources for various functions. For example, the tissue removal system 11 and the ultrasound imaging system 12 may have separate power sources.
  • [0030]
    While particular forms of the invention have been illustrated and described herein, it will be apparent that various modifications and improvements can be made to the invention. For example, the discussion herein has focused on ultrasound imaging. Those having ordinary skill in the art will recognize that other imaging systems may be employed, for example x-ray or mammographic imaging. To the extent not previously described, the various elements of the biopsy system may be made from conventional materials used in similar devices. Moreover, individual features of embodiments of the invention may be shown in some drawings and not in others, but those skilled in the art will recognize that individual features of one embodiment of the invention can be combined with any or all the features of another embodiment. Accordingly, it is not intended that the invention be limited to the specific embodiments illustrated. It is therefore intended that this invention be defined by the scope of the appended claims as broadly as the prior art will permit.
