Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control system, and more particularly to a control system characterized by a portion for controlling a plurality of medical devices.

[0002]

2. Description of the Related Art An example of a system composed of a plurality of medical devices is a medical endoscope system including an endoscope.

A typical endoscope system is, for example, an endoscope for making an observation, a camera head connected to the endoscope, and an endoscope for processing an image signal picked up by the camera head. Camera device, a light source device that supplies illumination light to the endoscope to illuminate a subject, and a monitor that displays an endoscopic image obtained by signal processing by the endoscopic camera device. ing.

In the endoscope system described above, the endoscope is inserted into the region to be examined, and the light source device illuminates the subject with illumination light to obtain an optical image of the subject. The endoscope system is designed to display the subject image captured by the camera head on a monitor.

With such an endoscope system, the inside of a body cavity or the like is observed and inspected. In addition, surgical operations using an endoscope are also performed.

In this endoscopic surgery, in addition to the above-mentioned device, a pneumoperitoneum device used for expanding the abdominal cavity, a high-frequency ablation device for cutting or coagulating living tissue, and the like are used under an endoscope. Each treatment is performed while observing the multiple treatment site.

Here, in the conventional endoscope system, for example, Japanese Patent Application No. 2001-269304 previously filed by the present applicant.
And the RS-232C as described in No.
With the centralized control device that transmits and receives data by serial communication, it was possible to manage the set values and measured values of the peripheral devices. Moreover, by using a tool such as a setting panel, various setting values can be changed and data can be easily manipulated. Furthermore, by using a portable information terminal or the like on the setting panel, it was possible to apply it to a mobile setting / display unit that changes settings while updating measurement data in real time.

[0008] At that time, Bluetooth, wireless LA
If you use a communication standard such as N or wired LAN, you can communicate with multiple devices, and you can also control from multiple devices without fixing one portable information terminal for controlling peripheral devices. And, I was able to configure a system that was easier to use.

[0009]

In the endoscope system described below, the central control unit and the RS-23 are used.
The pneumoperitoneum device, the light source device, and the treatment device that communicate by wire in 2C, and the patient monitor device that communicates by wire via LAN are referred to as a plurality of peripheral devices. Further, a mobile information terminal such as a PDA that communicates with the centralized control device by wireless Bluetooth is referred to as a mobile device.

In the above-mentioned endoscope system, when the setting of the pneumoperitoneum device, which is a peripheral device, is changed, the centralized control device updates the information by serial transmission of RS-232C. After that, the data updated in the centralized controller is a communication method whose communication speed is different from that of the above-mentioned method.
It will update information to one or more mobile devices in Bluetooth.

Then, depending on the communication state of the mobile device, the time until the update is completed may vary. Especially in a device such as a wireless device, if there is a device of a standard using the same frequency, the communication speed may be slowed due to radio wave interference. Therefore, the time when the data is updated by RS-232C and the data update of the mobile device are performed. There is a gap in the time to complete, it takes time to update, communication Erro
There was a possibility of causing r. In addition, there are many wireless devices in the operating room, which interfere with each other.

[0012] Further, in wireless communication, there is an advantage that an obstacle can be passed, but in terms of software processing, data loss due to the obstacle increases the error rate, and command retransmission increases, so the communication speed decreases. Occurs. Therefore, if the data rate becomes slow in the pneumoperitoneum device, the treatment device, or the patient monitor device that polls at an early timing, a polling error may occur.

That is, for example, when the biometric information is displayed from the patient monitor, the data update interval is fast and the number of parameters is large. Therefore, if there is an error at the completion of data update due to a difference in communication speed, important biometric information It becomes impossible for Dr to find the change in the above condition, and it becomes difficult to perform the surgery.

The present invention has been made in view of the above circumstances, and has an information update speed between a peripheral device and a centralized control device.
Even if there is a difference in the information update speed between the mobile device and the centralized control device, it is possible to reliably transmit and receive information, reduce the deviation of the displayed information, and efficiently perform endoscopic surgery. Is intended to provide.

It is composed of a switch 110 and an antenna 111.

The baseband unit 75 is composed of a radio control / calculation unit 70 having a control / calculation processor for processing a signal digitized from the RF 71, and the CPU 31 for the central control of the central control unit 22. It is a configuration that can exchange signals with.

The communication status rating unit 77 is provided for controlling the monitoring process, the constant data update, the communication restriction process, and the flow of communication data.

In the present embodiment, the processing of the CPU 31 is entirely software.
When, for example, a touch panel or the like is controlled to handle an image, which will be described later with reference to the flows of FIGS. 11 to 14, the CPU 31 has a heavy load because the specifications cannot be processed in the MHz band. It is difficult to perform data monitoring of the communication storage unit while communicating all of the plurality of controlled devices with one CPU without using a considerably high specification.

Therefore, the DSP (Digital Si)
It is more preferable to use a device developed for real-time processing of data having a high transfer rate, such as a general processor (Gal Processor), and to perform high-speed processing in another routine. Compared to the CPU 31, the DSP has a configuration suitable for the present invention in which the processing content is simple but high speed is required.

Further, the communication is not restricted by the CPU 31, but is restricted by hardware, and a signal which detects the data transfer and is used as a trigger is constituted by the hardware from the above DSP when the data is being transferred. It is more preferable to generate the timing of the communication control unit.

Further, in controlling the above-described system, a clock signal required for each is generated from a reference system clock (not shown), and a timing generator for synchronizing processing is provided to limit communication and transfer data. Needless to say, description will be omitted using the drawings.

In the present configuration, the control by the CPU 31 is performed by polling whether the internal data of the peripheral device, the centralized control device 22 and the mobile device 5 match each other, so that the measurement / setting information of the measurement data is set in real time. This is a configuration capable of performing synchronization control.

The communication status monitored in the present embodiment means that communication is down, communication is possible, or blue.
Representing each mode referred to in the specification of oooth, the communication information is preferentially updated by the pneumoperitoneum device 14 which is a device whose data is updated quickly, or the light source device 16 having no measurement data has a priority order. It is information that can be lowered.

In Bluetooth, it refers to information about the time taken for communication to be recognized as being in a good communication state, the time taken for establishing communication in wireless communication, and the communication processing time at the time of data polling.

Further, when the data of each device is normally updated by 2s polling, it is possible to change to 1s polling when it is necessary to closely monitor the pressure display of the pneumoperitoneum in a certain operation based on the above information. .

11 and 12 show a control flow up to data updating with the central control device 22 and each mobile device when a control command of the light source device 16 is operated among the peripheral devices. The destination priority determination process of FIG. 11 is shown in FIG.
It is linked to the communication destination priority determination processing of No. 2. Here, when the communication-disabled state is recognized in the mode confirmation, it is removed from the candidates for the synchronization packet transmission, and the communication confirmation is performed after the synchronization of other devices is completed.

FIG. 13 shows the light source device 1 from the mobile device 5.
6 is a control flow when a light amount UP operation of 6 is performed. 11 and 12 described above is that the command information from the mobile device 5 is recognized by the central control device 22, the data of the light source device 16 is updated, and the display of the plurality of mobile devices 5 is updated. . On the contrary, FIGS. 11 and 12 show the light source device 1.
The command information from 6 is recognized by the central control device 22,
The mobile device 5 is updated. The priority destination determination process of FIG. 13 is for wireless and is linked to FIG.

FIG. 14 shows a process of determining the priority in the case of a peripheral device composed of a plurality of wired devices in the priority determination process. When controlled by the centralized control device 22, the control flow becomes when the data from a plurality of peripheral devices are simultaneously recognized.

(Operation) The operation will be described in the first embodiment configured as described above. First, when performing endoscopic surgery, the endoscopic surgery system 3 is set as shown in FIG. CO 2 gas from the gas cylinder is sent by the pneumoperitoneum device 14 to inflate the inside of the body cavity of the patient to secure the field of view of the endoscope. Light from the light source device 24 is guided into the body cavity of the patient, the illuminated body cavity is imaged by the camera device 15, and the display device 19 monitors the image. The electric scalpel 13 is used to treat the affected area.

At this time, the central control device 22 manages those peripheral devices 6, displays the set values / measured values of the peripheral devices 6 on the central display panel 20, and recognizes the command selected on the operation panel 19. However, it is reflected in the peripheral device 6.

Further, the centralized control device 22 manages the measurement data from the patient monitor system 4 for monitoring the biological information such as the pulse, the body temperature and the electrocardiogram of the patient, and the centralized control device 22 controls the endoscope of the camera device 15. The character of the measurement data is superimposed on the image and monitored on the display device 19. Further, if the communication between the central control device 22 and the patient monitor system 4 is limited to the LAN, it is possible to manage a plurality of patient monitors on one network.

Furthermore, when the command UHI shown in FIG. 5 is selected using the tool of the mobile device 5 which can be displayed, the detailed setting as shown in FIG. 6 is switched to the setting / display screen 65 for remote control, and the command 67 flow rate is displayed. When UP is pressed, the mobile device 5 causes the centralized control device 2 to
2 is wirelessly communicated.

As a specific operation, the user selects a command while looking at the liquid crystal display screen shown in FIG. 5, the command input is accepted by the operation unit, and the central control unit 22 is received from the I / F unit 36 of the mobile device 5. To the central control unit 22
It is received by the I / F unit 35.

At the time of reception, in the I / F unit 35, the switch driver 74 switches the switch 110 to the receiving side via the transmitting / receiving antenna 111 of FIG. 9, and the receiving unit 73 receives it. The receiving unit 7 detects the correlation of the frequency hopping, inputs it to the baseband unit 70 through the filter, and processes the received data in the wireless control / arithmetic unit 70.

When the communication from the mobile device 5 is performed, the communication state determination unit 34 performs the following processing.

When the centralized control device 22 is a host,
A peripheral device capable of communication is discriminated, its ID is recognized, and an address capable of holding a communication state / information is assigned. next,
For example, when an operation command is executed by the mobile device 5 and is received by the central control device 22 via wireless communication, the ID is recognized and the reception state information is stored in the communication state 95.

Here, Bl described in the present embodiment is used.
In case of uetooth, there are four modes. That is, the active mode represents communication, the sniff mode represents a mode in which monitoring of a controlled device is reduced and data is transmitted only to a specific device when communicating with a host and a plurality of controlled sides, and the hold mode is It represents a mode that the controlled side can enter during one-to-many communication and can perform other processing other than connection operation in the current network. Park mode is a mode in which it is not necessary to participate in the communication in the network and only synchronization is maintained. It represents.

The above-mentioned information on the communication state is stored in four modes, and further, information on whether communication is possible or not. If only Bluetooth is used, a comparison is made in the above four modes when prioritizing each mode.

In this way, the centralized control device 22 monitors the state of each mobile device 5. Furthermore, since the centralized control device 22 is also a display device, it constantly polls the measurement information from the peripheral device 6 and updates each mobile device 5. At this time, the time required for processing from transmission to data update and reception completion is stored as the reception sensitivity and is constantly updated, and the latest reception sensitivity information is always stored in the communication state storage unit. Further, as the peripheral device information, the device error information, the treatment device, and the priority level of the patient measurement data are designated in advance.

Based on these settings, the operation will be described with the flow from FIG.

In FIG. 11, the centralized controller 22 polls the measurement information and setting information of the controlled device in step S1. In step S2, the CPU 31 reports the information obtained by polling and the time taken for communication to the communication state determination unit 34.
The data in the communication status storage units 76 and 77 are updated.

Here, in the connection recognition at the time of the first connection of communication, the CPU 31 constantly monitors the port of the I / F unit 8 and when the connected device receives a response from the controlled device, In order to receive the ID and recognize what device is connected, the ID at the time of confirmation of connection is assigned to a specific area of the communication status storage units 76 and 77, and the polling information is stored at the assigned address. Needless to say.

In step S3, the user operates to increase the light amount of the light source device 16. In step S4, the CPU 31 recognizes the ID and the changed information, and prepares the transfer destination of the update data in step S5.

Next, the state of the transfer destination is confirmed, and step S6
If the communication is restricted in step S7, the process proceeds to step S7, and it is determined whether the transfer destination is in communication or other factors. If communication is in progress, the process waits until the communication process ends in step S9, and otherwise, a process for investigating factors such as failure detection other than device-by-device communication is performed in step S8. When the communication restriction is removed in step S6, the destination priority process of step S10 is performed.

FIG. 12 illustrates a destination priority process for wireless devices in order to update the change information from the peripheral device 6 to a plurality of mobile devices 5.

B recognized in step S11 of FIG.
Performs sequential processing of devices in the Bluetooth network. The mode of each mobile device is determined in step S12, and if communication is not possible, the mode is removed from the transfer destination in step S17. Only those communicable are sorted in step S13, and the latest communication processing times are compared in step S14.

However, it is also possible to compare the time of connection when entering the network without using the latest information.

Here, for example, the mobile device 5 (3) has 3
Assuming that it takes 00 ms, the mobile device 5 (1) has 500
ms, the mobile device 5 (4) has a poor reception state, has many data drops, and has a high error rate.
It takes 0 ms. Then, the result of step S14 is in the order of the speed of the mobile device 5 (3)> the mobile device 5 (1)> the mobile device 5 (4).
At 15, the data is transmitted in ascending order. When the data transmission is completed, the mobile device 5 removed in step S12
The communication state of (2) is confirmed and communication establishment processing is performed. if,
Here, if the communication state has improved, data update processing is performed.

In the above processing, data is transmitted sequentially even if a method of collectively transmitting data is broadcast on a general LAN network. Therefore, the data having a good communication state of each device is given priority. To reduce the time required to update the data of all devices,
Complete the synchronization. If you send data randomly or without prioritizing, it takes time to process incommunicable devices and communication conditions are not good,
A device in a good state is put off and it takes time to complete the entire synchronization.

Next, in FIG. 13, when the setting value of the peripheral device 6 is changed by remote control from the mobile device 5 side, the data of the operated peripheral device 6 is updated, and then the data of all mobile devices 5 is updated. The flow up to is explained.

As shown in FIG. 13, steps S1 and S2 are the same as in FIG. In step S3a, for example, the light amount of the light source device 16 of the mobile device 5 (1) is increased. The CPU 37 of the mobile device 5 (1) recognizes the change in step S4a, and the CPU 3 of the central control device 22 recognizes the change.
1 to the change information in step S4b. Step S
At 5, the CPU 31 recognizes the change information and transmits data to the peripheral device having the obtained ID. At this time, if there is communication restriction in S7, the same processing as described above is performed below, and if there is no communication restriction, the data is transmitted to the light source device 16 and data is changed in step S21.

When the CPU 31 recognizes that the data of the light source device 16 has been updated, it confirms the communication state restriction in step S22. Next, the communication destination priority determination process is performed in step S26, and the data transmission process to the mobile device 5 (steps S23 to S25) is step S7 in FIG.
~ The same as step S9.

FIG. 14 shows the priority level when data update from a controlled device composed of a plurality of peripheral devices 6 and mobile devices 5 managed by the centralized control device 22 is recognized during communication reception, for example. This is a flow for efficiently performing data update by performing processing in order from the highest processing.

As shown in FIG. 14, in step S31, the overpressure Error of the pneumoperitoneum Error (= control command C1) and the increase in light amount operated by the user (= control command C2),
When the pneumoperitoneum air supply START (= control command C3) from the mobile device and the light source device communication Error (= control command C4) can be recognized, the peripheral device 6 which is indispensable in the operation among the controlled devices in step S32. Or the remote control or the mobile device 5 for display is detected, and the mobile device 5 is assigned to the one with lower priority in step S37.

In step S33, only the peripheral device 6 remains, and in step S34, peripheral device priority comparison processing is performed.

Next, among them, the pneumoperitoneum device and the treatment device such as the electric scalpel are prioritized according to the priority for each device.

Then, the order of control command C1> control command C4> control command C2 is set, and the data of the overpressure Error is first updated in step S35. When all the devices have been updated, the other updates are sequentially performed. Here, only the warning may be re-prioritized and the other processing may be invalidated. After that, the processing of the removed device is performed in step S37.

Further, it is possible to reduce the processing time by distributing a plurality of received control commands for each device and collectively performing block transmission from the communicable device or the device having high priority.

The block transmission referred to here means that in the command transmission, consecutive addresses are grouped into READ / W.
Since the processing is quick when the WRITE is performed, when a plurality of control commands are received, the processing time is shortened by distributing the data to each device and holding the data at a new address and performing the block transmission for each device.

In this embodiment, the mobile device 5 is a personal digital assistant such as a PDA. However, even if a display such as a liquid crystal display or a plasma display is used or a plurality of liquid crystal touch panels are used, By equipping the device with a wireless unit and having the centralized control device 22 manage the same, the same operation can be performed. Therefore, when managing a plurality of controlled devices from one host like wireless communication, priority is given to each device to enable efficient processing.

In this system, which requires constant synchronization of internal data between mobile devices, the communication status is monitored for each communication method and for each device, and the device is selectively prioritized when transmitting and receiving data. By exchanging data, there is an effect that data can be transmitted and received efficiently and the time required for data synchronization in the system can be shortened. As a matter of course, for the user, the device that needs the display update is updated quickly, so that the user does not feel inconvenience and does not hinder the endoscopic surgery.
