Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a control device for controlling a plurality of medical devices and the like.

[0002]

2. Description of the Related Art In recent years, for example, endoscope devices have been widely adopted in the medical field and the industrial field. In particular, in the medical field, in addition to the endoscopic device, a system configuration in which another endoscopic peripheral device (medical device) such as a high-frequency cautery device (electric scalpel device) is connected to perform endoscopic surgery or The case of performing endoscopic diagnosis is widely performed, and a conventional example thereof is, for example, Japanese Patent Laid-Open No. 7-303654.

In this system, a plurality of medical devices connected to a system controller (control device) are centrally controlled, and when an error (or trouble) occurs in the connected medical device, the system controller sends the error via a communication line. The error content is detected and displayed, and the error is easily resolved.

[0004]

However, in the conventional example, a trouble due to a malfunction of the equipment can be detected by monitoring the operating state of the equipment, but the user is familiar with the operation method. The trouble related to the setup, which is performed until the device is used due to a mistake in setting the device or a connection error between the devices due to the absence of the device, etc., is normal because the operation of the device is normal. It has a drawback that it cannot be detected, and that it is not possible to show how to deal with the trouble. In addition, there is a drawback in that it is not possible to specifically show a coping method for recovering from an error or trouble.

An example of overcoming the conventional drawbacks is Japanese Patent Application No. 2001-32749. In this prior art, even when an undetected error or trouble occurs, a coping method or the like for recovering from the trouble or the like is shown to facilitate the recovery work to a state without trouble. However, in the conventional example, since the troubleshooting methods are listed, the operator has to try the listed troubleshooting methods one by one until the trouble is resolved. If there were multiple possible solutions, it would be redundant work.

(Object of the Invention) The present invention has been made in view of the above-mentioned points, and by displaying preferentially a coping method for a cause which is likely to be a main cause of a trouble encountered, It is an object of the present invention to provide a user-friendly control device that is easy to solve efficiently.

[0007]

In a control device to which a controlled device can be connected, information on occurrence probabilities for each cause of a predetermined operating state of the controlled device and the control device during use time of the control device is displayed. Occurrence probability storage means for storing, coping information storage means for storing coping method information in association with each cause of the controlled device and the control device being in the predetermined operating state, and usage time of the control device And a probability-of-occurrence reading unit that reads out information of the probability of occurrence for each cause stored in the probability-of-occurrence storage unit based on the time-of-use calculated by the time-of-use calculating unit. Based on the occurrence probability information read out by the read-out means, the coping method information stored in the coping information storage means is selected based on the cause for which the occurrence probability is high. When a trouble occurs, priority is given to displaying the countermeasure information for the cause having a high probability of causing the trouble from the usage time by providing the countermeasure information display means for displaying the trouble. Therefore, by taking action according to the displayed action method information, it is possible to efficiently and efficiently eliminate the trouble that has been encountered.

In response to the operation, the PU 15 can control the pneumoperitoneum device 6 to variably set the pressure inside the body cavity. It is also possible to operate the other operation buttons 20 to increase or decrease the cutting output. That is, the CPU 15 centrally controls the operation of the pneumoperitoneum device 6 that can be controlled by the controlled device connected to the system controller 8.

Further, near the lower left of the main screen G0, for example, an operation button 21a for returning to the normal screen and a maintenance mode switching button (hereinafter simply referred to as maintenance button) 21b for selectively designating a maintenance screen or a trouble item are provided. It is provided. Note that FIG.
Status send button 2 to send the system status
1c is displayed. This status send button 21
c does not work if the system 1 is not connected to an external device via the communication interface 18. The operation in the case of being connected to the external device via the communication interface 18 will be described in the second embodiment described later.

When maintenance is performed, when the maintenance button 21b is pressed, a menu window screen G displaying trouble items as shown in FIG. 3 is displayed.
1 is displayed. In this case, the right part of FIG. 3 is not yet displayed.

When displaying trouble items on the menu window screen G1 shown in FIG. 3, the trouble items are divided into major items,
It is displayed in a hierarchical structure. For example, a large number of subordinate items belonging to the major trouble item, such as a monitor image abnormality, a printer image abnormality, etc., such as noise, no image, ... I am trying to display small items.

In FIG. 3, a large number of subordinate items included in the large trouble item are simultaneously displayed in the large trouble item, but only the large trouble item is displayed and one of the large trouble items is designated. In this case, a large number of lower trouble small items included in the designated trouble large item may be displayed hierarchically. The user may be allowed to select both display methods.

Then, this menu window screen G1
In, when the position of the trouble item is designated by touching the position of the trouble item with a finger, a screen of a coping method for eliminating or recovering the trouble item, that is, a trouble recovery window screen G2 is displayed on the right side. FIG. 3 shows a trouble recovery window screen G2 corresponding to a case where a trouble item "color is wrong" indicated by cross-hatching is designated. In the trouble recovery window screen G2 of FIG. 3, and indicate that there are two screens.

As will be described later, when a trouble item is selected and designated, the CPU 15 performs a process of estimating the cause of the trouble item, and a recovery operation or an operating method for recovering from the trouble item according to the processing result. Is estimated and the information of the processing result is displayed on the control panel 13. That is, the CPU 15 performs a process of estimating a recovery operation or an operation method for recovering from the trouble item. In the case of FIG. 3, for example, as a troubleshooting for the item that the color of the monitor screen is wrong, the jump switch 22 is displayed together with the display of the coping method such as re-adjusting the white balance.

Then, in accordance with the display on the trouble recovery window screen G2, the jump switch 22 provided on the display portion is operated in order to perform the corresponding operation. Then, the recovery operation screen G3 for performing the recovery operation shown in FIG. 4 or the advice screen G4 for displaying instructions or advice information such as the operation method for recovery shown in FIG.

The recovery operation screen G3 displays operation information of the operation buttons 20 and the like for recovering the trouble item by directly operating. That is, in the recovery operation screen G3,
When an operation for touching the instructed operation button 20 is performed, the operation is sent from the control panel 13 to the CPU 15, and the CPU 15 controls the operation of the device corresponding to the operation. As a result, there is a possibility that the trouble item can be recovered. The contents of the trouble recovery window screen G2 of FIG. 3 and the contents of the trouble display screens of FIGS. 4 and 5 are not directly related.

If the trouble item is not resolved by operating the operation button 20 or the like on the recovery operation screen G3, the return button 23 displayed on the screen G3.
By operating, it is possible to return to the upper layer screen, that is, the screen G2 in FIG. 2, and it is possible to quickly operate other coping methods.

When the return button 23 is operated when the trouble item is not solved even if the operation button 20 or the like is operated, the setting state of the device is changed by the operation of the operation button 20 or the like, and therefore the setting of the system 1 is performed. When the state also changes, the setting by the operation button 20 or the like may be canceled to return to the state before the operation.

Further, in the recovery operation screen G3 of FIG. 4, the operation buttons and the like of the items that are not related to the elimination of the trouble item are displayed in diagonal lines so that the operation is not accepted even if the operation button is operated. It should be noted that although hatched in FIG. 4, the operation buttons not related to the elimination of the trouble item may not be displayed.

FIG. 5 shows an advice screen G4 in the case where the trouble-resolving operation cannot be performed using the operation buttons provided on the control panel 13. In this case, for example, a wiring diagram related to the solution of the trouble item of the system 1 is displayed, and an advice display for confirming the wiring of the cable indicated by the dotted line is displayed. Note that FIG. 5 shows that, for example, in the case of a trouble item that cannot be printed, the connectors A and B of the cable connecting the TV camera and the video printer may not be correctly connected to the TV camera and the video printer. Displayed when

In the above description, it was explained that the screen of FIG. 3 to FIG. 4 or 5 is moved depending on the method of coping with the trouble item, but the contents of FIG. 4 and FIG. 5 may be displayed simultaneously on one screen. FIG. 6 shows the mixed screen G5 in this case. In this mixed screen G5, for example, together with an operation screen including at least one operation button to be operated in order to solve the trouble item, a wiring diagram related to the solution of the trouble item is reduced and displayed at the same time, for example, a cable indicated by a dotted line. Also displays advice such as confirming wiring.

Further, as shown in FIG. 5, an advice screen G
When the connection diagram as 4 is displayed, the connection diagram as the advice screen G4 may be enlarged and displayed as shown in FIG. 7 in order to complicate the portion to be displayed or to make it easier to understand. .

When displaying the advice screen G4 shown in FIG. 5, a screen G6 showing icons as shown in FIG. 8 is displayed.
Is displayed in advance and the icon is clicked (touched)
In that case, a connection diagram including a video cable corresponding to the icon may be displayed as shown in FIG. Further, instead of displaying the reduced wiring diagram as shown in FIG. 5, the cable icon shown in FIG. 8 may be displayed instead. In addition to this, for example, when it is desired to display a wiring diagram at a plurality of locations, a thumbnail display in which the wiring diagrams at a plurality of locations are reduced may be used instead.

In the case of FIG. 3, the causes of the trouble of incorrect colors are as follows: (1) white balance operation error, (2) liquid crystal monitor color setting failure, (3) camera, monitor hardware failure, etc. (4) The backlight of the liquid crystal monitor may change over time.

FIG. 10 shows the probability of occurrence of trouble caused by the causes of (1) to (4) as a function of time.

In FIG. 10, the occurrence probability of (1) is Fp1.
The occurrence probabilities of (t) and (2) are Fp2 (t), the occurrence probability of (3) is Fp3 (t), and the occurrence probability of (4) is Fp4.
(T). The probability information is stored in the storage medium 16 described above. CPU 15 is control panel 13
Then, the occurrence probabilities Fp1 (t) to Fp4 (t) of (1) at the time when the maintenance button 21b is operated are calculated.

As can be seen from FIG. 10, the occurrence probabilities Fp1 (t) to Fp4 (t) of (1) change with time. The occurrence probability Fp1 (t) of (1) is the occurrence probability related to the erroneous operation of the white balance of the television camera, and this mainly depends on the equipment operation proficiency of the operating room staff who sets the camera before the operation.

The occurrence probability undulates in time because the members of the operating room may change regularly or irregularly, and immediately after the change, the proficiency decreases and the erroneous operation is not established. It seems that it will be higher.

However, by using the TV camera for a long period of time, the proficiency level of all the staff members in the operating room increases, and the range of fluctuation tends to decrease with time.

The occurrence probability Fp2 (t) of (2) is a probability of erroneous setting such as color setting of the liquid crystal monitor, which is not related to time, and the occurrence probability is almost the same and does not change largely.

The occurrence probability Fp3 (t) of (3) indicates the occurrence probability of defective hardware such as a television camera, a liquid crystal monitor, and a video cable. Generally, the probability of occurrence of hardware failure is slightly high in the initial stage, stable in the middle term, and in the latter term, it shows a U-shaped transition in which the probability of failure occurs due to aging of parts and the like and the probability increases.

The occurrence probability Fp4 (t) of (4) represents the color change due to the change with time of the backlight of the liquid crystal monitor, and this has the characteristic that the occurrence probability increases with time at a certain point of time.

In FIG. 3, when "color is wrong" is selected as the trouble item, the CPU 15 at that time calculates the occurrence probability F (t) of the cause relating to "color is wrong", and is displayed on the right side of the screen of FIG. As a coping method, the items with the highest probability of occurrence are displayed. For example, at t1 (initial stage of introduction) in FIG. 10, the respective probabilities are Fp1 (t)> Fp3 (t)>.
Fp2 (t)> Fp4 (t).

At t2 in the middle period, Fp2 (t)> F
p1 (t)> Fp3 (t)> Fp4 (t).

At the later stage t3, Fp4 (t)> Fp2
(T)> Fp3 (t)> Fp1 (t).

Therefore, at the time of t1, the contents of the trouble recovery window screen G2 of FIG. 3 are from the top, (1) operation error of white balance, (3) defective hardware such as camera and monitor, (2) liquid crystal. Monitor color setting error,
(4) The coping method regarding the secular change of the backlight of the liquid crystal monitor is displayed in order. As a result, when a trouble occurs, the action to be taken is shown starting from the one that is most likely to occur, and a quick response is possible.

Similarly, at the time of t3, the contents of the trouble recovery window screen G2 of 3 are from the top, (4) secular change of backlight of liquid crystal monitor, (2) defective color setting of liquid crystal monitor, (3) ) The countermeasures for defective hardware such as cameras and monitors and (1) white balance operation error are displayed in order.

In this embodiment, the menu window screen G1 for displaying the trouble item is displayed in this way, and when the trouble item is selected and designated by the display, the CPU1
A major feature of the present embodiment 5 is that, in each connected device, the probability of occurrence of the cause corresponding to the trouble item is calculated and displayed as the coping method in descending order of occurrence probability.

The operation of the medical device system 1 will be further described with reference to the flowchart of FIG. As shown in FIG. 1, each device to be used is connected and the power is turned on. Then, the CPU 15 of the system controller 8 causes the recording medium 1
The operation program recorded in 6 is read to recognize each device connected to the system controller 8.

The display surface of the control panel 13 is shown in FIG.
It is possible to display a main screen (normal operation screen) G0 as shown in Fig. 1 to display information on the setting state of the main device, and to perform operations such as settings for controlling the operation of the main device.

In this case, the CPU 15 identifies the type and function of the connected device by the ID information of each device through the connection line with each device connected to the system controller 8 and also the setting state of the device. The control information can be read out or transmitted to the controllable device from the control panel 13 to perform the initial setting or the like. In addition, by operating the operation buttons 20 and the like provided on the control panel 13, the set value can be increased or decreased.

When a situation that seems to be a trouble occurs during use of the system 1 or the like, a maintenance button (displayed on the main screen G0 of FIG. 2) is displayed as shown in step S1 of FIG. Press 21b. Then, the screen for displaying the trouble item in step S2, that is, the main screen G0 of FIG. 2 is changed to the display of the menu window screen G1 shown in FIG.

In the menu window screen G1 of FIG. 3, the corresponding trouble item is designated as shown in step S3. Specifically, on the menu window screen G1, the trouble item corresponding to the trouble item is roughly checked, and the trouble item that is more concretely selected from the trouble item is selected and touched to reduce the trouble item. Specify the item. By specifying this trouble minor item, the specified contents are transferred from the control panel 13 to the CPU.
Sent to 15.

Then, as shown in step S4, the CPU 15 performs an estimating process for estimating the cause of the trouble item from the designated trouble item. For example, when the trouble item that the monitor screen is dark is specified, the connected TV camera (1) 3 in the medical device system 1 is specified.
In the configuration of a plurality of controlled devices such as A, the light source device (1) 4A, etc., the estimation is performed over the power supply system, the light source system, the signal processing system, the image display system, etc. that may cause the trouble item.

For this estimation, the devices connected as the medical device system 1 are recognized, information (data) such as the function of each of these devices and its configuration, and the probability of occurrence of each of the factors that cause troubles. In addition, information on the cumulative use time after the delivery of the medical device system 1 and the elapsed time from the delivery date is recorded in the storage medium 16 in advance.

Then, as shown in step S5, the CPU 15 extracts (lists) the main factors of the cause of the trouble by estimation and performs the processing of calculating the occurrence probability of the cause of the trouble. That is, when the main cause of the trouble is estimated, the CPU 15 is expected to cause the trouble when the trouble occurs from the occurrence probability information of the cause stored in the storage medium 16 as a function of the time t. Calculate the value of the probability of occurrence. It should be noted that the time t is the cumulative usage time after the medical device system 1 is delivered or the elapsed time from the delivery date (in other words, this elapsed time is the system controller 8 as a control device constituting the medical device system 1). Is the cumulative usage time or the elapsed time from the date of delivery).

At the next step S6, the CPU 15 displays the occurrence probabilities having the highest occurrence probability among the occurrence probabilities (generally plural) calculated at step S5 so as to be prioritized and displayed side by side. In other words, the items that are more likely to cause a trouble are displayed with priority. Further, information such as a coping method or a recovery method for the cause of occurrence is preferentially displayed (sequentially or side by side by ranking, etc.) as much as coping information for a cause of occurrence having a high probability of occurrence (and, By giving priority to the display and performing the work according to the displayed troubleshooting information, it is easy to efficiently recover from the trouble item).

In this case, the operation to recover as shown in step S7 is performed by, for example, the operation button 20 (shown in FIG. 2) provided on the control panel 13 (or further operation switches other than those shown in FIG. 2). The CPU 15 determines whether the operation can be recovered or the operation or work other than that can be performed.

If the operation button 20 can be used for recovery, a recovery operation screen displaying the operation button 20 is displayed as shown in step S8.
For example, if the control panel 13 can control the recovery operation screen, an up control button for increasing the light amount of the light source device (1) 4A is displayed on the display surface of the control panel 13, and the CPU 15 is operated by the operation. Controls to increase the amount of light, or displays the gain up control button to increase the gain of the TV camera (1) 3A,
If you operate it, you can increase the gain. And try to recover the trouble item.

The CPU 15 is controlled via the control panel 13.
When it is not possible to control the increase of the light amount of the light source device (1) 4A from the above, an advice or instruction is given to display the light amount up button of the light source device (1) 4A on the advice screen and perform the operation. To do.

On the other hand, in the case of a type that cannot be recovered by operating the operation button, an advice screen for performing the work is displayed as shown in step S9. On this advice screen, for example, display a wiring diagram and the like to check whether the connection condition of the connection cable between the TV camera (1) 3A and the monitor (1) 5A is correct, and display it so that the work can be performed easily. Do (advise).

After performing the procedure of step S8 or S9, the CPU 15 requests the judgment of whether the trouble item is recovered on the display surface of the control panel 13 (step S10). When the trouble item is recovered, the operation button 21a is operated (step S11) to return to the main screen (normal operation screen) G0 (step S11).
12) The maintenance process is ended.

On the other hand, if it is determined in step S10 that the trouble item is not recovered, the process returns to step S4, and the CPU 15 considers the result of the recovery operation or the like and performs the process of estimating the cause of the occurrence, and the process result. Estimate the method to recover from the trouble item based on the above.

In this case, there are a plurality of operations, methods, etc. for recovering from the trouble item, and if one operation or the like does not recover, there is a high possibility that the same estimation processing as in the previous step will remain in step S4. In step S5, the ones that have not been recovered before are excluded and the probabilities of the main factors are calculated, and in step S6, the ones that become the main factors are displayed side by side in order from the one with the next highest occurrence probability.
The handling information for which the handling information has a high probability of occurrence is preferentially displayed.

Then, the trouble recovery process is performed in step S7 and the like.

In this way, if the trouble item is not recovered even if all the operations and methods for recovering the estimated cause of trouble are performed, another cause of cause is estimated in step S4. Therefore, in step S5, the recovery method or the like to be recovered is estimated based on the estimation result.

By performing the above processing, it is estimated that the probability of causing a trouble item is high, and the estimated results are sequentially prioritized by a coping method having a high possibility of canceling them. If the trouble item is not resolved even after displaying it, by displaying the less likely coping method in consideration of the result, the user can easily perform the trouble item by performing the operation according to the display screen. Can be resolved.

As described above, according to the present embodiment, even when a trouble that is not detected occurs, the trouble item is specified by designating the trouble item, and the trouble is solved. In view of the time point, the information having the highest probability of occurrence is displayed, so that it is possible to quickly and easily recover the trouble by performing an operation, work, etc. according to the display of the information.

Next, a modification of this embodiment will be described below. This modification has the same configuration as that of FIG. 1 and a part of its operation program is different. More specifically, various conditions input by the user from the control panel 13 are stored in the storage medium 16, and the above input conditions are utilized in the estimation process when estimating the cause of the trouble.

In FIG. 1, the user inputs the conditions related to the occurrence of trouble from the control panel 13. For example, it includes the following. (1) Time elapsed since the start of endoscopic surgery (2) Time elapsed since the start of using the medical device system (3) Past medical device repair occurrence information (4) Number of medical device systems owned (5) Medical Frequency of use of device system By inputting such information on an input screen (not shown) of the control panel 13 and storing it in the storage medium 16, the CPU 15
Can obtain the following information when estimating the cause of trouble.

(A) User's proficiency in endoscopic surgery (B) proficiency in medical device system (C) proficiency in in-hospital maintenance system for medical equipment FIG. The calculation of the occurrence probability in step S5 becomes more precise.

For example, when the factor relating to the operation error is indicated by the probability α, this α can be expressed by the parameters A to C. In this case, fp1 shown in the first embodiment
(T) is represented by the following fp1 '(t).

Fp1 '(t) = fp1 (t) + α (α is not limited to a constant, but may be a function value of a factor such as time.) Therefore, based on this formula, a trouble occurs in view of the characteristics of the user. Since the cause can be estimated, the trouble can be resolved more quickly and surely.

When the cause of the trouble occurrence is estimated as described above, the countermeasure information for the cause with a high probability of occurrence is preferentially displayed so that the user can perform the countermeasure operation and work according to the countermeasure information. , There is a high possibility that the trouble can be resolved efficiently.

However, as described in the present embodiment, when the cause of the trouble occurrence is estimated, the cause having a high occurrence probability is preferentially displayed, and when the user specifies the cause having a high occurrence probability from the display. The display of the coping information also belongs to the present invention.
