• This application is related to, and hereby claims the benefit of U.S. provisional application No. 60/475,747, filed on Jun. 3, 2003, entitled BIOPSY CONTROL STATION, attorney docket number R0367-03500.
BACKGROUND
• The present invention relates generally to medical devices, and more particularly to a universal control consol for operating with a variety of medical devices. Still more particularly, the present disclosure relates to the design of a universal medical equipment control consol that interfaces with a variety of handheld medical instruments, and the method to control the same.
• Conventional medical equipment design typically requires separate, dedicated hardware and software control modules for each handheld medical device. Each of these devices requires a graphical display, microprocessor, interface circuitry and software to operate the medical device, and to provide the operator with pertinent status/action information. An “operator” is defined as any medical personnel capable of operating the medical device. The operator may be a nurse, a medical doctor, or a medical assistant.
• The graphical user interface (GUI) will vary from device to device, thereby resulting in additional cost for operator training, proficiency, and certification. As the number of dedicated control modules increases, surgical and storage spaces must necessarily increase, as must the complexity of inventory logistics.
• What is needed is a universal control consol that can control a variety of medical devices, thereby eliminating the need for separate, dedicated control hardware for each medical device.
SUMMARY
• In view of the foregoing, a universal medical equipment control consol is provided that interfaces with a variety of medical devices.
• This disclosure will provide a detailed description of how a medical device interacts with the universal medical equipment control consol. Additional medical devices may be implemented. This concept allows for a universal control consol with all the necessary hardware interface modules and software modules that can control a variety of medical devices, thereby eliminating the need for separate, dedicated control hardware for each medical device.
• This universal control consol will provide a graphical user interface (GUI) for all devices that would decrease the need for operator training and certification requirements while increasing the simplicity of operation. Additional benefits include reduced surgical space, storage space, and inventory logistics costs. Some advanced models of the universal control consol may have the ability to handle multiple devices simultaneously.
• In one example, a control consol is disclosed for controlling one or more medical devices. The control consol communicates to at least one medical device and, if needed, at least one peripheral device module associated with the medical device. The control consol is microprocessor based for directing an operation of the connected medical device.

DESCRIPTION
• FIG. 1A presents a diagram100 illustrating the relationship between theuniversal control consol102 and a plurality ofmedical devices104,106 or108 in accordance with one example of the present disclosure.Devices104,106 and108 represent some of the many individual medical devices that may connect or communicate to theuniversal control consol102 via aconnector110 or via wireless communication links. Many of the medical devices are controllable by a computer based operating tool so that the universal control consol can communicate and control the medical device in many ways without human interaction. In the following illustration, wherever it is said that a device or module is connected to another device or module, it is understood that the term “connected” may also mean that they can be connected wirelessly without physically connected through wires. In most of the time, at least one device will be connected to and operational with theuniversal control consol102. Theuniversal control consol102 may also have a bypass mode in which a medical device may not be connected. Theuniversal control consol102 may interface with and control the functions of any one of thedevices104,106 and108 via theconnector110.
• In one embodiment, each of thedevices104,106, and108 may represent a biopsy probe, temperature probe, heart rate monitor device, drug infusion tools, anesthesia tools, or other surgical or medical device that may operate with theuniversal control consol102. These devices may serve various surgical or non-surgical functions such as separating specimen from tissue bed, encapsulating the separated specimen, insulating a cutter from body, fixing one end of a cutter while S5 moving another end thereof. These devices may be made by or operated with products of SenoRx of Aliso Viejo, Calif. such as the SenoCor Biopsy Device and the EnCor Biopsy Device. The surgical devices may be energized mechanically or through radio frequency (RF) energy for performing the surgery. For instance, a RF surgical tool uses RF energy to remove unwanted body parts while the same function may be achieved by a mechanical tool such as a blade. Each of these medical devices may require aunique set112 ofperipheral modules114,116 and118, which are connectable to and controlled by theuniversal control consol102 viaconnectors120,122 and124, respectively. As an example, thedevice104 may be a biopsy probe, which in turn may require a plurality ofperipheral modules114,116 and118, which further in turn may be an electro surgical generation (ESG) module, an illumination device, a footswitch module, and a vacuum/fluid pump module. It is understood that peripheral modules provides additional features or functions for the operation of the medical device, and can be of different forms and functions, and they may not be required to be physically connected to the universal control consol as long as they can communicate therewith. In some cases, the peripheral devices are controlled by the medical device through the universal control consol.
• Theuniversal control consol102 is a microprocessor-based electrical device with built-in software functions necessary to operate various medical devices. Each medical device contains a software script, stored in a memory device within the medical device for operating that particular device when connected to theuniversal control consol102. 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 medical device is connected to theuniversal control consol102, this software script will be downloaded into the universal control consol random access memory (RAM). This software script will enable theuniversal control consol102 to control the functionalities of the particular medical device and to display its pertinent information. During the operation of a medical device, the Graphical User Interface (GUI) software will display information relevant to the operation of theuniversal control consol102 and the medical device to the operator. It is understood by those skilled in the art that the information displayed may vary depending upon the type of medical device connected, the operational state of the medical device as well as other environmental factors affecting the operation of both the medical device and theuniversal control consol102.
• It is understood that although traditionally the medical devices are connected to theuniversal control consol102 through wired connections (including connectors and wires) or battery powered for their operations, the control of the medical devices by theuniversal control consol102 can be easily implemented through wireless communications. Needless to say, certain peripheral devices may have to be physically connected to the medical device to deliver fluid or assert vacuum. The conventional wired connections have certain advantages such as low signal interferences, but the wireless technology can turn the operation of the medical device to mobile operation, which benefits the operator as well. For example, other than the power output provided by theuniversal control consol102, 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 medical device is battery powered, then the operation may be all mobile. It is also practical that the wired communication channels may be used together with the wireless communication channels so that the universal control consol can take advantage of the available wireless technologies for providing convenience to the operator, while still benefiting from using some conventional wired technologies. Similarly, analog signals used in the communications can be replaced by digital signals if appropriate since the digital signal processing technology has also advanced. In short, while the present disclosure only provides some examples for illustrating the inventions, it should be understood that communications between devices can take various forms and theuniversal control consol102 is designed to use the most practical technologies for fulfilling the need of the operators.
• A housing module may also be provided to house, and to supply electrical power to, some of the aforesaid modules and equipments. An example is provided inFIG. 1B, which is a schematic diagram126 illustrating the relationship among ahousing module128, theuniversal control module102 and theunique set112 ofperipheral modules114,116 and118. Thehousing module128 includes apower strip130, which connects, via apower cord132, to an electrical power source, such as a 220-240V AC power source. Thepower strip130 is utilized to distribute electrical power to a plurality of modules and equipments. Aline cord134 may be utilized to deliver electrical power from thepower strip130 to theuniversal control module102. A plurality ofline cords136,138 and140 may also be utilized to deliver electrical power from thepower strip130 to theperipheral modules114,116 and118, respectively. It is understood that thehousing module128 may provide docking stations (not shown) for the handheldmedical devices104,106 and108. It is further understood that thehousing module128 can be a cart or a portable cabinet; that thepower strip130 and the aforesaid modules are fixed-mounted or screw-mounted onto thehousing module128; that thehousing module128 includes a plurality of moving wheels and accessible handles; and that thehousing module128 includes a wire latch that organizes and secures a plurality of line cords and data cables. Essentially, thehousing module128 functions as an organizer, a power distributor and an ergonomic solution for the operator to access the plurality of modules and equipments.
• FIG. 2 illustrates several components of theuniversal control consol102. Theuniversal control consol102 includes agraphics module202, amicroprocessor module204, asoftware module206, ahardware interface module208, anoperator module210 and apower module212.
• Thegraphics module202 may include a cathode ray tube (CRT) display, a liquid crystal display (LCD) or any other type of display that may be used to display information relevant to the operation of theuniversal control consol102 and medical devices. Thegraphics module202 may also require a piece of Graphical User Interface (GUI) software that is used to display all pertinent information to the operator.
• Themicroprocessor module204 may include microprocessors, motherboard circuitries, memories and other functional electronic devices that enable theuniversal control consol102, the operator controls thereof, the functions of medical device, and the functions of peripheral modules. It may also interface with an external computer via an external computer interface connector for system troubleshooting, software upgrade, and other shop functions.
• Thesoftware module206 controls the logical and interface functions of theuniversal control consol102, the logical and interface functions of the medical devices attached thereto, the logical and interface functions of the peripheral modules attached thereto, and the operator control switches therein. Thesoftware module206 may also generate various control signals such as audible tones (for example, sounds of Bong, Click, and Alarm) that are applied to a speaker located within theuniversal control consol102. The Bong and Click tones may be adjustable by a predetermined setting. Depending on software specification, the alarm tone may or may not be adjustable. As an example, the software may be written in “C” code, although it is understood by those skilled in the art that various other software languages may be used to write the software for theuniversal control consol102. Specifically, thesoftware module206 may include any combination of the following: core software operating theuniversal control consol102, GUI software for presenting graphics in thegraphics module202, built-in self-test (BIST) software, and software for controlling and interfacing with medical devices and peripheral modules. Each medical device, when connected to theuniversal control consol102, may download a software script. This software script will allow for the control of the particular medical device functions and display its pertinent information.
• Thehardware interface module208 may include circuitries and connecting modules necessary to allow medical devices or peripheral modules to be connected to theuniversal control consol102. These connecting modules may be general connectors compliant with various well-known standards, including but not limited to Institute of Electrical and Electronics Engineers (IEEE) standards and International Organization of Standardization (ISO) standards. These connectors may also be proprietary connectors specific to a particular medical device or peripheral modules, or a particular line of medical devices or peripheral modules. In addition, the connecting modules may be a circuitry for communicating wirelessly with a device controlled by the universal control consol.
• For example, thehardware interface module208 may have a computer interface connector. The computer interface connector is used for system troubleshooting, software upgrades, and other shop functions. This connector contains connectors for RS-232 communication, connectors for background debug mode (BDM), and connectors for other shop activities. In another example, thehardware interface module208 may have an AC power input connector, which may be a three-wire connector connectable to 100-120 VAC and/or220-240 VAC, at 50-60 Hz. In yet another example, thehardware interface module208 may have an AC power output connector, which is connectable to other peripheral equipments and which provides the other equipments with AC power. In yet another example, thehardware interface module208 may have a DC power output connector, which is connectable to other peripheral equipments and which provides the other equipments with DC power. It is understood that either DC or AC power can be delivered to an illumination device such as a light bulb or any surgical lighting device attached to or integrated with a medical device such as a biopsy probe used with the control consol. The control consol may provide further remote operation control for the illumination device.
• Other hardware interface circuitry and connectors implemented into theuniversal control consol102 may depend upon the medical devices and its associated peripheral equipment that have been certified to operate with theuniversal control consol102. As additional medical devices are selected, upgrades to the hardware and software may be required. Since analog and digital signals may co-exist in various operations, the universal control consol may have analog-to-digital (A/D) converters or even digital-to-analog (D/A) converters contained therein for processing various signals coming in or going out from the universal control consol.
• Referring back to the previous embodying example, the biopsy probe may require an ESG module, a footswitch module, and a vacuum pump module. The biopsy probe and its associated peripheral modules in turn may require the following interface connectors: a medical device connector, an ESG connector, a footswitch connector, and a vacuum pump connector.
• The medical device connector may contain a plurality of copper wires for bi-directional digital communications, EEPROM communication, encoder functions, light emitting diode (LED) & relay control, motor control, power, and ground. The ESG connector may provide bi-directional communication for the control and status of the ESG module and theuniversal control consol102, and may include a RS-485 data bus for status communication. The footswitch connector may pass information from the footswitch module to theuniversal control consol102, thereby allowing the operator to control the ESG module and theuniversal control consol102 by the tapping of the foot. Finally, the vacuum pump connector may provide data and control information between the vacuum system anduniversal control consol102. It may contain system data and clock lines, vacuum level and control lines, and status lines.
• Theoperator module210 may include various pushbutton switches and indicators that assist the operator to operate theuniversal control consol102. For example, there may be, adjacent to the display screen, three operator pushbutton switches that are under software control. The function of the switches may be dependent upon the display screen at a particular instance. The display screen displays the required actions and what action may be activated with a particular switch at a given instance.
• To further illustrate how theoperator module210 assists the operator, theoperator module210 may have two indicator lights, one of which is an orange standby indicator light on the front panel that may be activated when the rear mounted power switch is depressed and the system enters a standby state, while the other of which is a green indicator light on the front panel that may be activated when a front mounted power switch is depressed for a minimum of 2 seconds, thereby signaling theuniversal control consol102 to kick-start its boot up sequence. When the front mounted power switch is depressed again for a minimum of 2 seconds, the display may indicate that theuniversal control consol102 is in the process of shutting down. During an orderly shutdown, theuniversal control consol102 may complete any actions required by the medical device, save any required settings, and then return to the standby mode.
• Thepower module212 may include a transformer, AC power input and output connectors, a power system, fuse, and a power switch. Thepower module212 may supply power to the rest of theuniversal control consol102, and may supply power to other peripheral modules and medical devices attached thereto.
• FIG. 3 illustrates a frontal andtop view300 of theuniversal control consol102 embodying features of the present invention. The front of thecase enclosure302 includes agraphical display screen304, various operator control switches306, amedical device connector308, afront power switch310, an orange “standby”indicator light312, and the green “on”light314. It is understood that theconnector308 is an example for a connecting module which either physically connects to a device or wirelessly communicates to a device without any physical connection existing therebetween.
• FIG. 4 illustrates a rear andbottom view400 of theuniversal control consol102 shown inFIG. 3. The rear of thecase enclosure402 includes apower module404, afootswitch connector406, avacuum connector408, anESG connector410,spare connectors412 for future medical device/peripheral equipment additions, and the externalcomputer interface connector414 behind theremovable panel416. Thepower module404 includes theinput power connector418,output power connector420,AC power fuse422, and therear power switch424. The bottom of theenclosure402 includes thealarm speaker426 for the Bong, Click, and Alarm tones.
• FIG. 5 presents aflowchart500 illustrating the relationship between various display screens, which are referred to and shown inFIG. 6, in accordance with one example of the present disclosure.
• In particular, theflowchart500 illustrates the software flowchart covering the initial boot-up, medical device connection, utility mode setup, boot-up alarm sequence and the downloading of the medical device script. A general high-level software flow502 illustrates how the software module generally handles any medical device that is connected to theuniversal control consol102. This software flow may be unique for each medical device operation.
• Theflowchart500 begins at a boot-upprocess504 that occurs when the power-on sequence is started. Indecision box506, theuniversal control consol102 checks the shop mode jumper to determine if the system should go into the shop mode for troubleshooting/upgrade, as illustrated bybox508, or continue the normal boot-up process. Adecision box510 determines whether a language selection screen should be displayed to the operator to select the desired operator language. If the language selection screen should be displayed, a language screen, which may look like thescreen602, may be displayed. This selection is accomplished through the use of the pushbutton switches located adjacent to the graphical display screen. The universal control consol software script controls the functions of these switches. Once the desired language is selected, a boot-up splash screen that may look like thescreen604 is displayed.
• If the medical device has been connected, the script will go directly to download the medical device script, and a screen that may look like thescreen606 is displayed to the operator. If an alarm is generated during the boot-up process, the script will transfer to the boot-upalarm screen608 to ask the operator to reset the system. If no medical device has been connected, a bypass mode screen that may look like thescreen610 may be displayed, wherein the operator is asked to connect the medical device or to access the utility menu. If the operator connects the medical device, then the script goes directly to the device script download mode and thescreen606 may be displayed. If the operator wishes to enter the utility mode, then the operator depresses the “SELECT” pushbutton switch, thereby switching to the utility screen, which may look like thescreen612. The utility menu allows the operator to adjust the volume level, which may be accomplished in a volume level screen that may look like thescreen614, to adjust the display screen intensity level, which may be accomplished in a display screen intensity level screen that may look like thescreen616, or to go back to thescreen610 such that the operator may connect the medical device. Once the correct volume or display screen intensity is selected, the operator is transferred back to the bypass mode screen. When the medical device is connected to theuniversal control consol102, the script goes directly to the device script download mode andscreen606 may be displayed. Once the script is downloaded, the downloaded script controls theuniversal control consol102 and its display as determined by the type of medical device connected. Inflow502, the connected medical device determines the system operation and display screens. One example of the system operation and display screens inflow502 are presented, in detail, in FIGS.10 to17. Through this flow, the appropriate control configuration of a medical device is managed by theuniversal control consol102. For example, it detects and configures itself to match the operating configuration of the medical device. For example, it detects and provides an appropriate voltage supply for operating the medical device. It may also provide control signals to control the motor in the medical device. It may provide appropriate GUI windows to the operator with regard to the medical device so that the operator only needs to deal with relevant GUI windows for operating the medical device. If a vacuum pump is needed to be used in conjunction with the medical device, it not only will indicate to the operator whether a vacuum pump is properly connected, it will also provide the appropriate operating voltage to the vacuum pump. In short, theuniversal control consol102 is to assist the operator to operate multiple medical devices with ease. To the extent possible, all configurable items for operating the medical device are either automatically provided to the device or prompted to the operator to be chosen so that they can be then provided to the connected device.
• The three pushbutton switches are utilized in the displays that require an operator action, such as language selection, volume adjust, reset, etc. It is understood by those skilled in the art that all display screens inFIG. 6 are presented to illustrate the spirit of the invention, are subject to change, and are not considered to be the only version.
• FIG. 7 presents aflowchart700 illustrating the high level interactivity between various software components of theuniversal control consol102 in accordance with one example of the present disclosure. The components include amain module702, a tool-code module704, an application program interface (API)module706, acore software module708 that in turn includes a self-test module710 and aGUI module712, acontrol software module714 that in turn includes acommunication control module716, a vacuumpump control module718 and amotor control module720, aRF control module721, and a binary I/O module722.
• Themain module702 contains software functions for the operation. For example, it includes a reset function in assembly code that is required to start the controller and run a portion of the self-test. Themain module702 also includes a high-level code that runs the main loop and performs some additional self-tests, including memory and processor tests.
• The tool-code module704 loads the tool code from nonvolatile memories into the code buffer of the volatile memories and then runs tests thereon. The tool code may be tested by a variety of methods. For example, one tool code testing method is by using cyclic redundancy check (CRC). The tool-code module704 may also allow theuniversal control consol102 to write to nonvolatile memories.
• Another functionality of the tool-code module704 may include the testing of nonvolatile memories. In other words, the tool-code module704 may run periodic tests to ensure that nonvolatile memories are not corrupted.
• TheAPI module706 may include an API called by the tool code, and an API manager that is used to manage the said API. The API is used by the tool-code module704 to request theuniversal control consol102 to act in a certain manner. As an example, one implementation strategy may call for the use of software interrupts to request certain API routines, via theAPI module706.
• The self-test module710 may include built-in, self-test (BIST) software that is used to perform various self-testing operations. Most of these self-testing operations should be non-invasive, i.e., they should test for mis-configuration, but should not actively induce one.
• TheGUI module712 may include software that is used to draw outputs to the screen. ThisGUI module712 may also include functions such as the initialization of the color palette upon boot-up, the drawing of the first splash display screen, and the refreshing of subsequent display screens.
• Thecommunication control module716 may include software that controls the inputs and outputs through the RS-485 connector. Thecommunication control module716 keeps all information about a port in a table, which is typically indexed to ensure fast referencing. The interrupt callback routines of thecommunication control module716 may be passed to a hardware access layer, thereby enabling theuniversal control consol102 to receive incoming data.
• The vacuumpump control module718 may include software that controls the vacuum pump system interface. For example, the vacuumpump control module718 may be able to detect vacuum and pump power. It may also be able to translate commands sent by theuniversal control consol102 to actual pressure, and vice versa.
• Themotor control module720 may include software that controls the motors located in the medical device. Themotor control module720 may provide theuniversal control consol102 with various operating modes. For example, themotor control module720 may provide a feedback-controlled operating mode, which may employ a variety of discrete proportional-integral-derivative (PID) feedback algorithms to provide feedback functionality. Themotor control module720 may also provide various constant operating modes, including constant current and constant voltage operating modes, which may be necessary for medical devices that require a steady motor. TheRF control module721 is dedicated to control devices using RF energy.
• The binary I/O module722 may include software that performs the binary input and output. For example, the binary I/O module722 maps an array of binary outputs to its corresponding array of hardware address registers, and writes data flags to the latter. For example, when the “power-off” button is pressed, the binary I/O module722 first searches for and locates the corresponding hardware address register, and then begins a power-off sequence. In another example, when a motor is stopped, the binary I/O module722 may read the corresponding hardware address and return a flag indicating that the particular motor has been stopped.
• The universal control consol embodying features of the present invention may be operated in regular ambient temperature and usually requires no special sterilization. The operating voltage may be from 100 to 240 VAC with corresponding standard current limits. It also meets other industry required environmental conditions such as the CISPR 11 or IEC 60601-1-2:2001 for electromagnetic generation and IEC601-2-2 Section 44.3 for drip, splash and immersion requirement. It also meets various international standards including various safety requirements for medical equipments in different countries such as Japan, Canada, EU, and US.
• FIG. 8 illustrates adesign1000 embodying the interaction between abiopsy device1002, as further illustrated inFIG. 9, and theuniversal control consol102 in accordance with one example of the present disclosure.
• General Design Specifications
• In this embodyingdesign1000, the medical device such as abiopsy device1002 consists of the SenoCorDR3000 biopsy driver1004 and a surgical element such as theSenoCor360biopsy probe1006. Thebiopsy probe1006 andbiopsy driver1004, when used in conjunction with theuniversal control consol102, aVS3000 vacuum system1008 and a SenoRxES300 ESG module1010, are designed to obtain breast tissue biopsy samples. The specifications of SenoCor DR3000,SenoCor360, VS3000 and SenoRx ES300 may be found at SenoRx's website, at:
• http://www.senorx.com/products/product catalog/index.asp
• With reference toFIGS. 3, 4 and8, theuniversal control consol102 is connected from themedical device connector308, via acontrol cable1012, to thebiopsy driver1004. When thebiopsy device1002 is connected as shown inFIG. 8, theuniversal control consol102 may provide user interface, motor speed control, and operator feedback for thebiopsy driver1004.
• Design Features
• The embodyingdesign1000 provides many features, four of which are highlighted below:
• 1) Radiofrequency (RF) Cutting Tip
• Thebiopsy probe1006 that attaches to thebiopsy driver1004 incorporates a disposable RF cutting tip. The RF cutting tip enables the device to slide easily through difficult heterogeneous breast tissue, and to penetrate through dense lesions, thereby improving the targeting capability of the device. RF energy is developed by theESG module1010, which is controlled by adual footswitch1014 and theuniversal control consol102. The generator-enable signal is routed from thefootswitch1014 via acable1016 to theconnector406, and then through theESG connector410 via acable1018 to a footswitch input connector on theESG module1010. Thecable1018, which may be designed for RS485 communication, provides a communication path to allow theuniversal control consol102 to configure theESG module1010 for thebiopsy device1002. The RF output from theESG module1010 is fed, via aRF cable1024, to aRF cable connector1026 of thebiopsy driver1004. Thepatient return pad1028 is connected to theESG module1010 via acable1030.
• 2) Integrated Coaxial Probe
• Thedisposable biopsy probe1006 consists of an inner cutting trocar and sample chamber with an outer probe. A trocar is a sharply pointed surgical instrument fitted with a probe and used to insert the probe into a body cavity, typically, as a drainage outlet. An outer probe is typically a small tube for insertion into a body cavity. After a lesion has been targeted, the outer probe remains in place while the inner sample chamber is removed following the removal of a biopsy specimen. The above functions are generated by DC motors in thebiopsy driver1004 that provide linear or rotary motions for thedisposable biopsy probe1006. Medical devices may contain up to four DC motors and each motor is driven by a DAC output located in theuniversal control consol102. These signals and the other required signals are routed through themedical device connector308 and thecontrol cable1012 to thebiopsy driver1004.
• 3) Circumferential Vacuum Assisted Biopsy System
• Thedevice1002 harvests tissue from a full 360-degree radius, thereby enabling harvesting of tissue directly from the center of the suspicious mass. This process is assisted by the use of the vacuum switch located on thedriver1004 to remove any excess fluid from the biopsy area. Vacuum is applied by thevacuum system1008 to avacuum tube connector1034 of thebiopsy driver1004 via avacuum tube1036. Thevacuum system1008 is under the control of theuniversal control consol102 via acable1038, which connects to thevacuum connector408.
• 4) Control Buttons
• With reference toFIG. 9, thebiopsy device1002 includes thebiopsy driver1004 and thebiopsy probe1006, and incorporates three easy to'use push buttons: “sample”, “vacuum”, and “eject”. To sample tissue, the operator pushes the “sample”button1102. To remove excess fluid from the biopsy cavity, the operator pushes the “vacuum”button1104. To change probes for the next operation, the operator pushes certain functional key or unlocking mechanism such as the “eject”button1106, after which the disposable probe is easily removed. There are two optical sensors to determine probe size (e.g., diameter) and indicate to the system that the disposable probe is in place or removed. It is understood by those skilled in the art that the actions associated with the said buttons may differ in different probe designs, dependent upon functional and software control requirements.

The outputs to the medical device in this example contain four wires for power (+12VDC, −12VDC, +5VDC, ground), six digital wires for LED indicators and relay controls, and eight wires for motor drive control (two wires per motor). The medical device is preferred to have up to 4 DC motors. For example, theuniversal control consol102 may provide 12-bit DAC outputs for each motor. There is a maximum of 2 Amps for all four motors. Each motor can draw up to 1 Amp, and maintain a 2 Amp-limit on all four motors. In addition, eight wires are used for EEPROM communication, two wires may be used for grounds (one for shield, the other for connector case), and five spare wires are included for future expansion. It is understood that various types of motors can be used by different medical devices, and theuniversal control consol102 can implement appropriate connectors for controlling the medical device with special requirement for the connector.
• 2) The Footswitch Connector
• Theconnector406 is a 12-pin connector, with shielded cable and with isolated I/O. The footswitch may use two wires for the active signals, one wire for the common return signal, one wire for a shielded signal and eight spare wires for future expansion.
• TheESG connector410. Theconnector410 is a 15-pin connector, with shielded cable and with isolated I/O. Theconnector410 may contain inputs and output to and from theESG module1010 for communicating its status or configuring theESG module1010 using a RS-485 communication bus; Theconnector410 may also contain several spare wires for future expansion.
• 3) The Vacuum Connector
• Theconnector408 is an 18-pin connector, with shielded cable and with isolated I/O. The connector uses two wires for vacuum system data and clock. The inputs contain four bits for vacuum level plus two bits for control. Also included are wires that carry power-on and vacuum-ready status signals.
• The externalcomputer interface connector414. Theconnector414 is a 14-pin connector, with non-shielded cable and with non-isolated I/O. It contains 10 wires for BDM communication, three wires for RS-232 communication, and one wire for the shop mode switch that is in turn used for system troubleshooting and/or upgrade.
• 4) The Input Power Connector

• 5) The Output Power Connector
• Theconnector420 is a 3-pin connector, with a non-shielded, removable cord. The output power may be 100/220 VAC, at 50 or 60 Hz.
• 6) Driver Components
• Thedevice1002 has the following components that are controlled by the software script downloaded into the universal control consol102:
• 7) Stroke Motor
• The stroke motor controls the axial motion of the cutting sleeve of thedevice1002. The motor is in turn controlled by themotor control module720.
• 8) Cutting Motor
• The cutting motor controls the rotational motion of the cutting sleeve of thedevice1002. The motor is in turn controlled by themotor control module720.
• 9) Vacuum And Sample Switches
• The vacuum and sample switches of thedevice1002 are contact inputs to digital inputs of thecontrol module102. The script uses the API as specified in theAPI module706 to retrieve the values of these inputs from thecontrol module102.
• 10) Vacuum LED
• The Vacuum LED of thedevice1002 is an output of thecontrol module102. The script uses the API as specified in theAPI module706 to control its state.
• The driver unit receives its power, control and status information via thecontrol cable1012 that connects to themedical device connector308 of theuniversal control consol102. Thedevice1002 requires a vacuum to remove any excess fluid in the biopsy area and to pull tissue into the biopsy area for subsequent cutting. This vacuum is applied via thevacuum connector1034 and controlled by the “vacuum”button1104 or the script software depending on the state of the tool. Controlled RF power or a mechanical cutter may also be necessary for thedevice1002 to cut through breast tissue. The RF power is applied through theRF cable connector1026 and controlled by thefootswitch1014. Also the script software can inhibit the footswitch use or turn on the RF power without the footswitch. Whenever a sample of the tissue is desired, the “sample”button1102 may be pressed to obtain the tissue sample.
• There may be other components that are needed for the medical operation. For example, sterile water or saline line is needed for various surgical operations, and it can be provided through and controlled by the control consol as well.
• 11) Flow Logic
• FIG. 10A presents aflowchart1200 covering the initial script initialization, normal surgical operation states, failure states, and tool exit states of thebiopsy driver1004 in operation with theuniversal control consol102 in accordance with one example of the present disclosure. Display screens are generated on thegraphical display screen304 of theuniversal control consol102 based on the state of the system. The system may display the status and user action information of theuniversal control consol102 and those of the medical device to the operator via various display screens during a surgical operation.
• With reference toFIGS. 5, 6 and10A, the display screens602 through616 cover from initial boot-up, medical device connection, utility mode setup, boot-up alarm sequence to the downloading of the medical device script. The specific states inFIG. 10A are unique to thebiopsy driver1004 operating with theuniversal control consol102 and are depicted inFIG. 5 as theflow502. Any other medical device attached to theuniversal control consol102 may have unique states and display screens for their operation.
• FIGS. 10B to10D present various display screens in relation to states inFIG. 10A in accordance with one example of the present disclosure. With reference toFIGS. 10A to10D, ascript initialization state1202 may have a display screen that looks like thescreen1204. In this state, initial system parameters, vacuum system parameters, and RF generator parameters are set. This state is initiated after the medical device script is downloaded to the universal control consol. If this initialization is successful, the flow goes to atool initialization state1206, whose display screen may look like thescreen1208 or thescreen1210, if this is a subsequent initialization due to a reset. If the vacuum initialization fails in the script initialization state, the flow goes to atool exit state1212. If an error occurs, the script will exit to the appropriate error state.
• In thetool initialization state1206, tools are initialized without a probe inserted. The tool cycles the stroke motor, by ensuring that it operates at the full stroke and is left in the closed position. On the closing stroke the tool operates the cutting motor, thereby checking for its function. The tool polls the probe's phototransistors to ensure that a tool is not inserted. The tool polls the switches available to the user (“vacuum”, “sample” and “foot switches”) to ensure that none of them is pressed at the end of the cycle of the stroke motor, a situation that may indicate a stuck contact. If a probe is inserted during this state, the software exits to the tool failure state and may display adisplay screen1214. If an error further occurs, the script will exit to the appropriate error state.
• In thecalibration state1216, if thetool initialization state1206 is successful, thescreen1218 is displayed while waiting for the surgical component such as a probe or a blade to be inserted. Once the probe is inserted, thecalibration state1216 first waits for the “sample” button to be pressed by the operator and then performs two short strokes to calibrate the tool, when thescreen1220 may be displayed. If an error occurs during calibration, such as when the stroke motor is not responding properly or the probe becomes unlatched, the script will exit to atool failure state1222 and displays thescreen1224. If an error further occurs, the script will exit to the appropriate error state.
• If calibration is successful, the flow goes to a biopsy area closedstate1226. The biopsy area closedstate1226 first waits for the “sample” button to be pressed and then opens the cutter. Instate1226, the script performs the following functions:
• • 1. Continually monitor for vacuum and generator system failures;
  • 2. Continually monitor for new foot switch and Sample switch presses;
  • 3. If a new footswitch press is detected and the “sample” button is not pressed, activate the RF Generator;
  • 4. If the “vacuum” button is pressed and held for approximately one second, enable the distal trim and display the distal trim enabled screen;
  • 5. If the “vacuum” button is pressed while distal trim is enabled, disable distal trim; and
  • 6. If the “sample” button is pressed and the footswitch is not pressed, go to the openingbiopsy area state1238.
• Some of the possible screens in thestate1226 are:screen1228, wherein the biopsy area is closed and RF is inactive;screen1230, wherein the biopsy area is closed but RF is active;screen1232, wherein the biopsy area is closed and RF is disabled;screen1234, wherein distal trim is enabled; andscreen1236, wherein the biopsy area is closed, RF is inactive and the footswitch is still pressed from previous RF activation.
• Thestate1226 typically goes to thestate1238 when the “sample” button is pressed. In thestate1238, the script performs an open stroke if the distal trim is not enabled and displays thescreen1240. It is understood that the operator may select a full or half stroke opening of a biopsy cutter, and some necessary GUI may be provided. When the open stroke is successfully completed, the flow goes to the biopsy areaopen state1242. If an error occurs during thestate1238, such as when the stroke motor is not responding properly or probe becomes unlatched, the script will exit to thetool failure state1222. If other errors further occur, the script will exit to the appropriate error state.
• In thestate1242, the operator is allowed to activate the vacuum module or ESG module (e.g., if distal trim is not enabled). When the “sample” switch is pressed, the flow typically goes to the closingbiopsy area state1244. The ESG module is disabled if this state is entered from the probe unlatched state PUS, where the probe became unlatched during the close & cut processing of thestate1244.
• Instate1242, the script performs the following functions:
• • 1. RF is disabled if this state is entered from the state PUS, where the probe becomes unlatched during the close & cut processing of the closing biopsy area state. RF is also disabled if distal trim is enabled;
  • 2. Continually monitor for failures from the vacuum and ESG modules;
  • 3. Continually monitor for a new footswitch press, a new “vacuum” button press and a new “sample” button press;
  • 4. If RF is not disabled, a new footswitch press is detected and the “sample” button is not pressed, activate the ESG module;
  • 5. If the “vacuum” button is pressed and the “sample” button is not pressed, activate the vacuum module; and
  • 6. If the “sample” button is pressed and the footswitch is not pressed, go to the closing biopsy area state.
• Some of the possible screens in the state1242 are: the screen1246, which is displayed upon successful completion of the state1238, or other states defaulting to the state1242 even as the state1242 is not explicitly listed; the screen1248, which is displayed after fast-closing processing failed but biopsy area is subsequently opened; the screen1250, which is displayed after entering from the state1238 after the state1244 and close and cut processing state have failed but biopsy area is subsequently opened; the screen1252, which is displayed after entering from the completion of the state1238 after the timer expired or the stroke motor has stopped during the state1238; the screen1254, which is displayed after entering from the state PUS, which is in turn entered from the state1244 during the close and cut processing state; the screen1256, which is displayed when ESG module is active; the screen1258, which is displayed when the vacuum module is active; the screen1260, which is displayed when entering from the successful completion of the state1238, or other entry points not explicitly listed; the screen1262, which is entered from the state1238 after the state1244 and the close and cut processing state have failed but biopsy area is subsequently opened; the screen1264, which is entered from the completion of the state1238 after the time expired or after the stroke motor has stopped during the state1238; and the screen1266, which is entered from the successful completion of the state1238 when distal trim is enabled.
• Instate1244, the vacuum module is activated for two seconds, and then thestate1244 starts the stroke motor to close the cutter and starts the cutting motor. If the “vacuum” button is pressed during the two-second vacuum period, the script will immediately start the stroke motor, at a rate faster than used when cutting, and will not start the cutting motor. When the close stroke is successfully completed, the flow goes to thestate1226. If an error further occurs, the script will exit to the appropriate error state.
• Instate1244, the script performs the following operations:
• • 1. If the distal trim is not enabled, turn on vacuum for 2 second pre-vacuum period;
  • 2. If the “Sample” button is pressed during the pre-vacuum period, start the stroke motor at a fast rate to just close the cutter (“Fast Close”). If the Sample button was not pressed, or if the distal trim is enabled, start the stroke motor to close the cutter and start the cutting motor;
  • 3. If the Sample button is pressed during a normal cutting operation (not a Fast Close), stop the motors, keeping the vacuum on. When the Sample button is pressed again, start both motors again; and
  • 4. After the cutter has closed, if the distal trim is enabled, start the cutting motor in the opposite direction for a brief period to perform the distal trim.
• Some of the possible screens in thestate1244 are: thescreen1268, which is displayed during pre-sample vacuum processing; thescreen1270, which is displayed during fast-closing processing; thescreen1272, which is displayed during close and cut processing; thescreen1274, which is displayed during the pause sample processing; and thescreen1276, which is displayed during distal trim processing. It is further understood that if in any one of thestates1216,1222,1226,1238,1242,1244, a medical device such as the biopsy driver is removed, all these states are routed tostate1212.
• FIG. 11A presents aflowchart1300 covering the unlatched probe processing state of thebiopsy driver1004 in operation with theuniversal control consol102 in accordance with one example of the present disclosure. When the probe is re-latched after being unlatched in the state PUS, the flow goes to astate1302, where the flow will stay until the probe becomes unlatched, when the flow goes back to the state PUS.
• The state PUS is entered from any operational (non-error) state that has a probe inserted in the device. The script prompts the user to reseat the probe as is displayed to the operator as screen1278. In most cases, this state exits back to the state the script was in when the error occurred. The exception is if the script was in thestate1244, in either the pre-sample vacuum or close and cut processing. In those cases, the state PUS exits to thestate1242, with the ESG module disabled if the error occurred during the close and cut processing.
• FIG. 11B presents a display screen in relation to the state PUS inFIG. 10A in accordance with one example of the present disclosure. Thescreen1304 is displayed when the probe is unlatched, thereby requiring the operator to reseat the probe and reset the device.
• FIG. 12 presents various display screens in thetool failure state1222 of thebiopsy driver1004 in operation with theuniversal control consol102 in accordance with one example of the present disclosure. The tool failure state is an error state that is entered when an error occurs that requires that the probe to be removed from the device. This state displays a message indicating the error that has occurred and then waits for probe to be removed. Various screens are displayed in the tool failure state: thescreen1402, when a probe was inserted in the device during thestate1206; thescreen1404, after a biopsy has failed and thesubsequent states1238 also failed; and thescreen1406, after calibration has failed and open stroke has failed to complete.
• FIG. 13A presents aflowchart1500 covering the ESG module failure states (EMFS), whose display screens are further illustrated inFIG. 13B, of thebiopsy driver1004 in operation with theuniversal control consol102 in accordance with one example of the present disclosure. When the ESG module failure is corrected after being triggered in the state EMFS, the flow goes to astate1502, where the flow will stay until the ESG module failure is triggered again, when the flow goes back to the state EMFS.
• With reference to bothFIGS. 13A and 13B, the state EMFS is entered from any state, except thestates1202 and1212, when the system detects a failure in the system. The script supports two types of ESG modules and the detection of a failure depends upon the ESG module type. The absence of any ESG module connected causes an ESG module failure. In addition, if a Type-C generator is detected, a failure is caused when it does not respond or if the patient pad is not connected when required. (It is required during calibration state and whenever ESG RF is activated.) The following screens are displayed in the ESG module failure state: thescreen1504, which is displayed when there is a patient pad failure; and thescreen1506, which is displayed when there is an ESG module failure.
• FIG. 14A presents aflowchart1600 covering the vacuum failure states (VFS), whose display screens are further illustrated inFIG. 14B, of thebiopsy driver1004 in operation with theuniversal control consol102 in accordance with one example of the present disclosure. When the vacuum failure is corrected after being triggered in the state VFS, the flow goes to astate1602, where the flow will stay until the vacuum failure is triggered again, when the flow goes back to the state VFS.
• With reference to bothFIGS. 14A and 14B, the state VFS is entered from most states when the system detects a failure in the vacuum module. The failure may be a result of the unavailability of the vacuum module (it becomes disconnected) or of a vacuum level that does not meet the minimum requirements. The script will wait for eight seconds to allow the vacuum module to recover, and may turn off the vacuum module and require the operator to press the “reset” button to continue.
• The following screens are displayed in the vacuum failure state: thescreen1604, which is displayed while the vacuum is recovering; thescreen1606, which is displayed after the vacuum is not recovered; and thescreen1608, which is displayed after vacuum has failed to recover.
• FIG. 15A presents aflowchart1700 covering the exit processing states, whose display screens are further illustrated inFIG. 15B, of thebiopsy driver1004 in operation with theuniversal control consol102 in accordance with one example of the present disclosure. When the driver is removed from any state, the tool exit state TES is triggered. Typically, if the time expires, or the ESG module is reconfigured, the flow goes back to a prior menu screen. If the driver is reconnected, the flow goes to thestate1206.
• The following screens are displayed in the tool exit state: thescreen1702, which is displayed after an integrity check for the ESG module has failed; thescreen1704, which is displayed after an integrity for the tool has failed; thescreen1706, which is displayed after the pump fails to initialize; and thescreen1708, which is displayed after the tool script exits normally.
• The above disclosure provides many different embodiments or examples for implementing different features of the disclosure. Specific examples of components and processes are described to help clarify the disclosure. These are, of course, merely examples and are not intended to limit the disclosure from that described in the claims.
• Although the invention is illustrated and described herein as embodied in a design and method for a universal reusable medical equipment control module, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the disclosure, as set forth in the following claims.
