As a result, the peripheral devices are centrally controlled by the control signal from the endoscope system control device 6.

Although FIG. 3 shows the case of the peripheral device connected to the serial line 17, the case of the peripheral device connected to the parallel line 18 is almost the same.

Further, the endoscope system control device 6 is connected to a set value storage unit 19 for storing set values and the like for each user who operates. Therefore, the setting of the peripheral device can be performed for each user with the setting value suitable for the user. As described above, the endoscope system control device 6 inputs and outputs control signals to and from each peripheral device connected to the endoscope system control device 6, and controls the operation of the peripheral device. .

In the present embodiment, the endoscope system control device 6 monitors the power consumption of the peripheral devices connected to the endoscope system control device 6, more specifically, the current consumption. Then, when the current consumption of the entire peripheral device exceeds a predetermined value, the endoscope system control device 6 leaves the power to the low-priority peripheral device while leaving the high-priority peripheral device. Controls such as shutting off the supply are performed.

Hereinafter, the configuration will be described with reference to FIG.

FIG. 4 is a block diagram showing an internal configuration of the endoscope system control device according to the present embodiment. As shown in FIG. 4, the endoscope system control device 6 includes a centralized control device 41 and a control device 42. The centralized control device 41 is constituted by a CPU board or the like and performs centralized control. The control device 42 is connected to the central control device 41 by a control line, and includes an embedded CPU and the like. Peripheral devices directly controlled by the control device 42 (under the centralized control of the central control device 41) are connected to the control device 42 via control lines. Examples of peripheral devices include a light source device 12, a video processor 13, an observation monitor 5, an air / water supply device 14, an electrocautery device 21, a video printer 22, a VTR 2 There are three.

The peripheral devices such as the light source device 12, video processor 13, ■ ■ ■, VTR 23, and the like, operate via a relay 43 a 43 g whose ONZO FF is controlled by the control device 42. Supplied.

In other words, the peripheral devices such as the light source device 12, the video processor 13, ■ ■ ■, and the VTR 23 include the breaker 44 in the endoscope system control device 6, the current sensor 45, the power switch 46, and the relay. Commercial power is supplied via 43a and 43g.

A main relay 47 is connected in parallel with the power switch 46. Therefore, when the power switch 46 is turned on, the main relay 47 is turned ON. Then, commercial power is supplied to each section via the main relay 47. If the power switch 46 is operated while the main relay 47 is ON, the main relay 47 becomes OFF. Then, the commercial power supplied to each part becomes OF.

That is, when the main relay 47 is turned on, commercial power is supplied to (the input terminal of) the DC power supply 48 via the main relay 47 that has been turned on. At the same time, commercial power is also supplied to peripheral devices such as the light source device 12, the video processor 13 and the electric knife device 21 via the relays 43a and 43e respectively connected to the main relay 47. You.

[0047] The DC power output terminal of the DC power supply 48 includes a central control device 41 and a control device.

42 are connected to supply DC power necessary for operation.

Further, the current sensor 45 detects a current supplied from the commercial power supply to the endoscope system control device 6, and sends the detected output signal to the central control device 41. Further, the control device 42 controls the ONZO F F of the main relay 47.

The central control device 41 has a built-in main memory 49. The main memory 49 is a memory used for a work area for executing a program and for holding necessary data. In addition, this central control unit 41 The hard disk 50 is connected. The hard disk 50 stores an operation system program and a current monitoring program (to be described later) which is an application program that operates on the operation system.

When the power of the system main body 2 is turned on, the CPU (not shown) in the central control device 41 reads a program in the hard disk 50 and performs a current monitoring operation.

Further, the control device 42 incorporates, for example, a flash memory 51 as an electrically rewritable nonvolatile memory. In the storage area 51a in the flash memory 51, for example, information on current consumption in a normal state in each peripheral device is stored. Then, when the centralized control device 41 enters the operating state, the centralized control device 41 receives the information from the control device 42 and determines a first threshold value which is set, for example, about 10% higher than the maximum current value in a normal state. Then, the central control device 41 stores the first threshold value in the main memory 49.

The flash memory 51 stores the maximum permissible current by the breaker 44 that defines the maximum permissible current in the system body 2, that is, the value of the breaker trip current that is cut off when the current exceeds that value. Have been. Then, the centralized control device 41 determines a second threshold value set to be lower than the value of the breaker trip current by, for example, about 50%, and stores the second threshold value in the main memory 49.

[0051] Then, when the centralized control device 41 is activated, it performs a current monitoring operation using the first threshold value and the second threshold value.

The operation of this embodiment with such a configuration will be described.

First, an operation when operating the endoscope system 1 of the present embodiment will be described. The user connects the endoscope 4 to the light source device 12, the video processor 13 and the like of the system body 2. Then, by turning on the power switch 46, the power of the peripheral devices connected to the system main body 2 is turned on, so that the endoscope 4 can be inspected by the endoscope. When performing treatment or treatment, an electric scalpel or the like connected to the electric scalpel device 21 is passed through the channel of the endoscope 4, or a heat probe device 24 or the like is used. Thus, treatment and treatment can be performed. At this time, the user can operate the operation panel 7 provided on the system body 2 to centrally control each peripheral device.

In the present embodiment, the central control device 41 detects the total current consumption value consumed by all the connected devices such as the light source device 12 connected to the system main body 2 by the current sensor 45. Monitor by current. In addition, the centralized control device 41 determines whether or not the total current consumption value corresponds to that in a normal use state, and performs control according to the determination result.

The operation of the current monitoring will be described with reference to FIG.

FIG. 5 is a flowchart illustrating a control process of power monitoring by the endoscope system control device according to the present embodiment. When the power switch 46 is turned ON, the centralized controller 41 starts and starts the operation of current monitoring.

As shown in FIG. 5, in the first step S1, the centralized control device 41 calculates a normal total current consumption value from the connected device, and determines a threshold value Ta corresponding to that case.

In other words, the centralized controller 41 is connected to the connected devices actually connected to the system main unit 2 from the controller 42 side (in the case of Fig. 4, the light source device 12, video processor 13, and observation monitor 5). Regarding the air supply / water supply device 14, the electrocautery device 21, the video printer 22, and the VTR 23), the total current consumption in a normal operation state is obtained from, for example, the flash memory 51.

Then, central control device 41 sets a value slightly larger than the maximum value in the normal operation state as threshold value Ta. The central control device 41 uses the threshold value Ta as a criterion for judging (determining) whether or not the operating state is normal.

[0058] In the next step S2, the centralized control device 41 sets a value slightly lower than the breaker trip current value based on the information of the breaker trip current value that causes the breaker 44 to perform the current interruption operation. Set as threshold Tb. And this In a state where the device is used with a current consumption exceeding the threshold value Tb, the function of current interruption by the breaker 44 may work. In this case, as described later, the current to the low-priority connected device is cut off.

In the next step S 3, centralized control device 41 reads the current consumption value actually consumed by the entire connected device from current sensor 45. Then, in the next step S4, the centralized control device 41 determines whether or not the threshold value Ta set for determining whether or not the device is in a normal state is larger than the actually consumed current value ( In other words, “T a ≥ actual current consumption of the entire connected device”) is determined.

If the result of the determination in step S 4 satisfies “threshold value Ta ≧ actual current consumption value of the entire connected device”, the process returns to step S 1 because it corresponds to a normal use state. In Fig. 5, it may be possible to cope with the case of returning to step S3, but by returning to step S1, the connected device actually used may be changed during endoscopy. In order to be able to respond to this, the process is returned to step S1.

On the other hand, if the result of the determination in step S 4 is “threshold value T a <actual current consumption value of the entire connected device”, centralized control device 41 determines that it does not correspond to a normal use state Then, go to step S5.

[0062] In step S5, the centralized control device 41 performs control processing for prohibiting use of the specific device, and then proceeds to step S6. In step S5, use of a specific connection device that is not an essential connection device for endoscopy, for example, the electrosurgical device 21 is prohibited. However, if in use, continuous use after use is prohibited. The control processing for prohibiting the use of a specific device is, for example, notifying that the use of the specific device is prohibited.

[0063] In step S6, the central control device 41 determines whether or not the threshold Tb set for the breaker 44 is larger than the actual current consumption value (that is, "Tb ≥ actual Current consumption value ”).

If the result of the determination in step S 6 is “threshold T b ≥ actual current consumption of the entire connected device”, the centralized controller 41 turns off the power as shown in step S 7. The user is notified that the current consumption value deviates from the normal range, and the process returns to step S1.

On the other hand, if the result of the determination in step S 6 is “threshold value T b <actual current consumption value of the entire connected device”, the centralized controller 41 ends the endoscope as shown in step S 8 Set the relays of connected devices other than the essential devices required for the inspection to OF. In this case, turn off the relays of the connected devices that have a low use priority for endoscopy.

In the case of FIG. 4, the light source device 12, the video processor 13, the observation monitor 5, and the air / water supply device 14 are essential devices for the endoscopic examination. On the other hand, the electrosurgical unit 21, video printer 22, and VTR 23 as other connected devices are connected devices having lower priority than the required devices. In this case, for example, first, the relay 43 f for the video printer 22 is turned off, or the relay 43 g for the VTR 23 is turned off. The priority of the connected device that has a lower priority than the required device is preset at the factory, but can be set by the user.

After setting the relay of the connected device having a low use priority to “OF” in step S8, in the next step S9, the centralized control device 41 deviates from the normal range of the current consumption value. The user is notified that the power of some of the connected devices has been set to OF, and the process returns to step S1.

[0068] Based on the current monitoring and the current monitoring result, the power supply to the connection device having a low priority is turned off to prohibit the use thereof, so that the power supply to the connection device indispensable for the endoscopy is provided. Priority can be given to use, and good operability can be ensured.

[0069] Specifically, the power supply to the essential devices can be increased by the amount of turning off the power of the connected device with a low priority, and the state can be set to be easier to continue the endoscopic inspection.

If the number of devices to be connected first is set too large, the breaker 44 that can be supplied by the breaker 44 in the system main unit 2 even under normal conditions It may exceed the current trip current. This case will be described with reference to FIG.

FIG. 8 shows an example of displaying information based on the total current consumption value in the screen example of the connected device in the present embodiment. If the total current value (14.1 A in Fig. 8) exceeds the current value (14.6 A) that can be supplied from the system main unit 2 on the connected device screen shown in Fig. 8, operate the power connection switch. By doing so, a power supply different from that of the system main body 2 may be set, and an indication that the power supply is different from that of the system main body 2 may be displayed using a separate power cord.

FIG. 9 is a flowchart of a process of performing a reconnection check by ONZOFF of power supply to each connected device in the present embodiment. In the present embodiment, when the power switch 46 is turned on (when the system body 2 is started), the threshold Ta is calculated from the result of the connection check processing operation as shown in FIG. The current monitoring operation may be performed.

[0072] As shown in step S11, when the power switch 46 is turned on, the centralized controller 41 turns on the main relay 47 as shown in step S12, and relays all connected devices. Change 4 3 a 4 3 g to OF

Then, in the next step S 13, the central control device 41

For example, a signal is sent to the light source device 12 via a control line to determine whether communication is possible.

If communication with the light source device 12 is successful in step S13, the central control device 41 determines that the connection of the light source device 12 is NG (unusual) as shown in step S14. Move on to step S15.

On the other hand, when communication with the light source device 12 is not possible in step S 13, the central control device 41 determines that the connection state of the light source device is OK, and proceeds to step S 15.

In step S15, the central control device 41 turns on the light source device relay 43a. In the next step S16, the central control device 41 sends a signal to the light source device 12 via a control line to determine whether communication is possible. Do.

If communication with the light source device 12 is not possible in step S 16, the central control device 41 determines that the connection of the light source device 12 is NG (incorrect) as shown in step S 17. After that, it moves to step S18.

On the other hand, if communication with the light source device 12 is possible in step S 16, the central control device 41 determines that the connection state of the light source device is OK, and proceeds to step S 18. Set the light source device relay 4 3 a to “OF”.

In step S 19 following step S 18, centralized control device 41 performs the same operation on video processor 13 as performed on light source device 12 in step S 13 Is determined whether communication is possible.

In this case, steps S 13 to S 18 are processing S a of connection check for the light source device 12, and the central control device 41 executes such processing S a by the video processor 13 and the like. The same applies to other connected devices. This process is indicated by Sb in FIG.

After performing the processes S a and S b for all the connected devices in this way, in step S 20, the central control device 41 executes the connection check process to

Judge the presence or absence of the NG connected device.

[0080] If there is no connected device of connection NG, central control device 41 ends the connection check process. If there is a connection device of connection NG, the central control unit 41 sets the relay of the connection device of connection NG to OFF in step S21 to prohibit use. Further, in step S22, connection N

G. Notify the user of the use prohibition information and end the connection check process.

[0081] Based on the connection check end result, the current consumption value in the normal operation state of the use-permitted device is read from the flash memory 51, and the total current consumption value in the normal operation state is added by adding each of them. obtain. The threshold value Ta is set based on the total current consumption value.

[0082] As described above, the ON N ZO of the power supply from the power supply line to each connected device is provided.

By performing FF, the control device 42 determines whether or not to perform communication via the control line. By doing so, it can be determined whether or not the individual connected devices are correctly connected, and the optimum threshold value Ta can be set.

Next, a second embodiment of the present invention will be described below with reference to FIG. 10 and FIG.

FIG. 10 is a block diagram illustrating an internal configuration of the endoscope system control device according to the present embodiment. FIG. 10 shows the configuration of the peripheral portion of the endoscope system control device 6B in the present embodiment in a state where connected devices are connected. In the endoscope system control device 6 according to the first embodiment shown in FIG. 4, only the current sensor 45 for detecting the current consumption value consumed by the connected devices is provided. The endoscope system control device 6B according to the embodiment further includes current sensors 61a to 61e so as to detect a current consumption value of each connected device.

That is, in the first embodiment, the relays 43 a 43 g are arranged on each power line connected from the power switch 46 and the main relay 47 to each connected device. In the embodiment, the current sensors 61a61e are provided in series with the relays 43a43e.

In FIG. 10, for the sake of simplicity, the connected devices will be described according to the case of the light source device 12, video processor 13, observation monitor 5, electrosurgical device 21, and video printer 22. I do.

[0086] The current values detected by the current sensors 6 1a to 6 1e are taken into the central control device 41 via the control device 42. Other configurations are the same as those of the first embodiment.

In the present embodiment, current monitoring as shown in FIG. 11 is performed.

FIG. 11 is a flowchart illustrating a power monitoring control process performed by the endoscope system control device according to the present embodiment. As shown in FIG. 11, when the power switch 46 is turned on, in the first step S31, the centralized control device 41 obtains information on the normal current consumption value of each connected device from each connected device. The threshold value for judging the normal and abnormal conditions of is determined. [0088] In other words, the centralized control device 41 is a device that is actually connected to the system main body 2 from the control device 42 side (in the case of Fig. 10, the light source device 12, the video processor 13, The maximum value of the current consumption value of the observation monitor 5, the electrosurgical device 21 and the video printer 22) in the normal operation state is obtained from, for example, the flash memory 51.

Then, centralized control device 41 sets a value slightly larger than the maximum value in a normal operation state as each current consumption threshold.

In the next step S32, the centralized control device 41 determines a value slightly lower than the break trip current value based on the information of the breaker trip current value that causes the breaker 44 to perform the current interruption operation. Set as threshold Tb.

In the next step S 33, centralized control device 41 reads current consumption value It actually consumed by the entire connected device from current sensor 45. Then, in the next step S34, the central controller 41 determines whether or not the threshold value Tb set for the breaker is actually larger than the total current consumption value It detected by the current sensor 45 ( In other words, T b ≥ It) is determined.

[0091] If the determination in step S34 does not satisfy the condition of Tb ≥ It, in step S35, the centralized control device 41 is not an inspection-required device required for endoscopy. Turn off the relay connected to the connected device from the one with the lowest usage priority.

[0092] Then, in the next step S36, centralized control device 41 notifies the user that the current consumption value deviates from the normal range and that the power of some connected devices is turned off. Then, the current monitoring process ends.

[0093] On the other hand, if the determination in step S34 satisfies the condition of Tb ≥ It, in step S37, centralized control device 41 does not require an endoscopic examination but does not require an examination. The current consumption values I d and I e of the current sensors 61 d and 61 e that detect the current of the device are taken into account.

[0094] Then, in the next step S38, the centralized control device 41 detects each current consumption threshold for each non-inspection required device by the current sensors 61d and 61e. It is determined whether the current consumption values are larger than the current consumption values Id and Ie.

[0095] If each of the current consumption thresholds is larger than the current consumption values Id and Ie, the central control device 41 determines that the current consumption is normal and proceeds to step S41. Conversely, when each current consumption threshold value is equal to or less than the current consumption values Id and Ie, the centralized control device 41 sets the relay of the corresponding device to OFF in step S39.

[0096] Further, in the next step S40, centralized control device 41 notifies the user that the current consumption value of the corresponding device deviates from the normal range and that the power supply of the corresponding device is "OF". Then, go to step S41.

[0097] In step S41, the centralized control device 41 includes the light source device 12 and the video processor 1 3 that are required for inspection by the current sensors 61a, 61b, and 61c.

The current consumption values Ia, Ib, and Ic of the observation monitor 5 are read.

[0098] Then, in the next step S41, the centralized control device 41 determines that each current consumption threshold is equal to the current consumption value Ia, which is detected by the current sensor 61a, 61b, 61c, respectively. It is determined whether or not it is larger than Ib and Ic.

[0099] In the determination in step S41, each current consumption threshold is determined to be the current consumption value Ia

, Ib, and Ic, the central controller 41 determines that it is normal and returns to step S33.

[0100] On the other hand, if it is determined in step S41 that each current consumption threshold value is equal to or less than the current consumption values Ia, Ib, and Ic, the central control device 41 deviates from the normal range. Then, the user is notified that the current consumption value of the corresponding device is out of the normal range, and the process returns to step S33.

[0101] According to the present embodiment, the current consumption value of each connected device can be monitored. Therefore, when the connected device that is not indispensable for endoscopy exceeds the current consumption value in a normal state, Shuts off the power to the connected device and prohibits its use, and informs the user of this. Therefore, more appropriate measures can be taken.

[0102] In the above description, the endoscope system 1 using the endoscope 4 has been described. However, the present invention can be similarly applied to other medical systems such as an ultrasonic diagnostic system and a medical microscope system. . [0103] Third Embodiment

In the present embodiment, an endoscope system which is a modification of the first embodiment and can obtain the same effects as the second embodiment will be described.

FIG. 12 is a flowchart illustrating a power monitoring control process performed by the endoscope system control device according to the present embodiment. FIG. 12 shows a flow obtained by adding S50, S51, S52, and S53 to the flow of FIG. First, in step S50, a counter variable i is initialized so that i = 0. Then, the processing of 51 54 was performed.

[0105] If the determination result of S4 is "threshold value Ta <actual current consumption value of the entire connected device", centralized control device 41 determines that it does not correspond to a normal use state, and Step S6 is performed. If the determination result in S6 is “threshold value Tb <actual current consumption value of the entire connected device”, the processes in S8 and S9 are performed, and the counter variable i is incremented in S53. Then, returning to step S1, the threshold value Ta is recalculated for the connected devices excluding the connected devices whose relays of the connected devices have been turned OFF in S8.

In S 4, while “the threshold T a <the actual current consumption of the entire connected device”, S 1

Repeat S9 and S53.

If “threshold value Ta ≧ actual current consumption value of the entire connected device” is satisfied in S4, it is determined in S51 whether or not the counter variable i is greater than zero.

If “counter variable i> 0”, there is a problem with the connected device that was last turned off, and the user is notified of that. Here, the value of the counter variable i corresponds to the order of the connected device whose power is turned off. Therefore, the user is notified that there is an abnormality in the connected device whose power is turned off at the ith position. Then, return to S1.

If the counter variable i = 0 in S51, the process returns to S1. The case where the counter variable i = 0 is the case where all the connected devices are normal.

According to the present embodiment as well, similarly to the second embodiment, it is possible to identify a connected device in an abnormal use state and appropriately control the connected device. [0108] As described above, according to the present invention, the power for executing the main functions such as cutting off the power supplied to the medical devices not related to the main functions of the plurality of medical devices constituting the medical system is described. Easy to secure.

According to the present invention, when performing endoscopy or the like by connecting a plurality of medical devices, the actual current consumption value is monitored and the maximum value when the actual current consumption value is normal is determined. Appropriate control is performed for a condition that exceeds the maximum value or a condition close to the maximum allowable value that is cut off by the breaker, and realizes an easy-to-use medical system.
