FIG. 8 is a flowchart showing the operation executed by the control means 52 of the foot controller 5.
The control means 52 waits until it detects any operation of the operation unit (joystick 5a to foot pedal 5c) (step S1: No).

  When the operation input is detected (step S1: Yes), the control unit 52 executes signal transmission (step S2). This signal transmission is composed of an operation signal when the operation unit (joystick 5a to foot pedal 5c) is operated, and a battery remaining amount signal indicating the remaining amount of battery of the power supply means 54 (remaining amount of secondary battery). ing. The remaining battery level is detected by a remaining battery level detection unit 54a provided in the power source unit 54.

  The control means 52 stands by until a response signal is received from the wireless communication means 43 and 46 provided in the medical chair 4 (step S3: No). When a predetermined time elapses during the standby and the time is over (step S4: Yes), the control unit 52 notifies the error by the notification unit 53 (step S5) and ends the process. This error notification is made by an appropriate method such as a beep sound or voice guidance that “the signal is not received correctly. Please use the touch panel monitor 8a”.

  When the response signal is received (step S3: Yes), the control unit 52 determines that the normal operation is completed and ends the process.

FIG. 9 is a flowchart showing the operation of the login process executed by the control means 24 of the medical device 7.
The control means 24 executes an initial setting process at the time of activation (step S11), and waits until login (step S12: No).

When a log-in operation is performed by the practitioner (step S12: Yes), the control unit 24 performs user authentication using a password or the like (step S13).
When user authentication fails (step S14: No), the control means 24 notifies an error to the display apparatus 10 or the touch panel monitor 8a (step S15), and returns step S12 processing.

  If the user authentication is successful (step S14: Yes), the control unit 24 determines whether there is a personal setting (step S16). This determination is made by referring to the user data 31 stored in the storage means 41 of the medical chair 4 and determining whether or not the setting data address is registered for the logged-in user.

  When there is a personal setting (step S16: Yes), the control unit 24 changes the foot controller setting data 32 stored in the storage unit 41 of the medical chair 4 to the registered personal setting (step S17).

When there is no personal setting (step S16: No), the control means 24 adopts the default setting (step S18).
In this way, after adopting either the personal setting or the default setting, the control unit 24 displays the main menu screen 70 as the medical screen with the adopted setting (step S19), and starts the medical processing ( Step S20). On the medical treatment screen displayed at this time, the name of the practitioner who has logged in at step S13 is displayed on the log-in user display unit 73, and the practitioner's settings including the setting of the foot controller 5 are clearly indicated. To do.

FIG. 10 is a flowchart showing the operation of the medical processing executed by the control means 24 of the medical device 7.
The control means 24 detects whether or not the instrument 16 has been taken in / out of the holder 14 by the instrument detection means 26 (whether it has been picked up or stored) (step S21).

  When the removal / insertion is detected (step S21: Yes), the control unit 24 acquires correspondence information regarding the setting of the foot controller 5 (step S22). Here, when the pickups of a plurality of instruments 16 are detected, the correspondence information of the instrument 16 that detected the pickup last is acquired.

  And the control means 24 changes the screen displayed on the display apparatus 10 or the touch panel monitor 8a, and the setting which can be operated with the foot controller 5 (step S23), and sets the medical treatment screen (setting screen 80A, 80B) by the setting after a change. Display (step S24).

  The setting information that can be operated by the foot controller 5 includes information on how the operation unit (joystick 5a, two-direction switch 5b, foot pedal 5c) is operated and how the medical device tray unit 9 and the medical chair 4 operate. This is associated execution foot controller setting data.

  The execution foot controller setting data is the same as that corresponding to the instrument 16 taken out from the holder 14 in the foot controller setting data 32. For example, when a high-speed handpiece (air turbine) is taken out as the instrument 16, the setting of the air turbine handpiece shown in FIG. 4B is read and changed, and the setting screen 80A shown in FIG. Is displayed.

  When all the instruments 16 are stored in the holder 14, the foot controller setting data 32 is the same as that corresponding to “all instruments stored”. In this case, only operations not related to the instrument 16 such as raising / lowering of the medical chair 4 are possible.

  If it is not detected in step S21 that the instrument 16 is inserted or removed (step S21: No), the control unit 24 moves to step S25 and confirms that no signal is received from the foot controller 5.

  When no signal is received from the foot controller 5 (step S25: No), the control unit 24 accepts an operation input to the touch panel monitor 8a (step S26), and executes a process corresponding to the accepted operation input (step S27). . In this process, appropriate operations such as setting change and driving of the instrument 16, ON / OFF of the light, and raising / lowering of the medical chair 4 are performed.

  When a signal is received from the foot controller 5 (step S25: Yes), the control unit 24 transmits a response signal to the foot controller 5 by the wireless communication units 43 and 46 (step S28). This response signal is transmitted from both the wireless communication means 43 and 46. Thereby, the foot controller 5 can receive a response signal reliably.

  If the signal from the foot controller 5 can be received by only a part of the wireless communication means 43 and 46 in step S25, a response signal is transmitted only from a part of the wireless communication means 43 and 46 that can be received. Also good. In this case, the foot controller 5 confirms which wireless communication means 43, 46 has received a response depending on whether there is a response from all of the wireless communication means 43, 46 or some of the wireless communication means 43, 46. And notification to that effect.

  The control means 24 determines whether or not the signal reception in step S25 has been received by all the wireless communication means 43 and 46 (step S29). If there are wireless communication means 43 and 46 that cannot receive even a part (step S29: No), the control means 24 indicates that there are wireless communication means 43 and 46 that cannot be received. 10 or the like (step S30), and the process proceeds to the next step S31.

  If the signal reception in step S25 has been received by all the wireless communication means 43 and 46 (step S29: Yes), the control means 24 proceeds to the next step S31 as it is.

  Here, even if some of the wireless communication means 43 and 46 have a reception failure, if the other wireless communication means 43 and 46 can receive signals from the foot controller 5 normally, the reception failure is notified. Without proceeding to the next step S31.

  The control unit 24 acquires a setting process corresponding to the received signal (step S31). Here, the received signal includes an operation signal for operating the operation unit (joystick 5a to foot pedal 5c) of the foot controller 5. The operation assigned to the operation corresponding to the operation signal is acquired from the execution foot controller setting data after the change in step S23. As a result, it is possible to acquire an appropriate operation corresponding to the instrument 16 that is currently taken out (or a state in which all the instruments 16 are stored).

  The control unit 24 determines whether the battery capacity is sufficient, and if it is sufficient (step S32: Yes), executes the operation of the acquired setting process (step S33). Here, “battery capacity is sufficient” refers to the case where the current battery remaining amount is larger than the operation regulation amount predetermined as the battery remaining amount that requires operation regulation.

  If the battery capacity is insufficient (step S32: No), the control unit 24 maintains the current operation state (step S34), and notifies the battery shortage by the display device 10 or the like (step S35).

  For example, if the instrument 16 is being driven, the current operation state is maintained without being stopped even if the stop operation signal is received. Alternatively, if the instrument 16 is stopped, the drive operation signal is maintained. This is done by maintaining the state as it is, such as stopping without driving even if it is receiving. Thereby, it is possible to prevent the instrument 16 from stopping suddenly and hindering treatment.

  FIG. 11 shows a flowchart of processing for transferring and registering the foot controller setting data 32 registered in a certain medical device 7 (the illustrated medical device 7A) to another medical device 7 (the illustrated medical device 7B).

  The control unit 24 of the medical device 7A waits until the setting transfer operation is performed by the touch panel monitor 8a (step S41: No), and when the setting transfer operation is performed (step S42: Yes), it is currently logged in. The foot controller setting data 32 of the user (practitioner) is acquired from the storage means 41 of the medical chair 4 or the memory of the control means 24 (step S42).

  The control unit 24 transmits the acquired foot controller setting data 32 toward the medical device 7B to which the control unit 24 wants to transfer (step S43). At this time, a specific medical device 7B may be designated and transmitted, or may be transmitted to all communicable medical devices 7. The transmission method is executed by an appropriate device capable of communication such as wireless communication by the wireless communication means 43 and 46, or wired communication through the CAN / BUS line 20.

  The control unit 24 of another medical device 7B waits until setting data is received (step S44: No). When setting data is received (step S44: Yes), the foot controller setting data 32 is registered and stored. (Step S45).

  The control means 24 of the medical device 7B transmits a response transmission to the medical device 7A that is the transmission source (step S46).

  If there is a response from the medical device 7B within a predetermined time (step S47: Yes), the control unit 24 of the medical device 7A displays a normal end on the display device 10 or the touch panel monitor 8a (step S48). (Step S47: No), error information is displayed on the display device 10 or the touch panel monitor 8a (Step S49), and the process is terminated.

  With the above configuration and effect, wireless communication can be performed, so that the presence of a real line between the foot controller 5 and the medical device 7 can be eliminated. For this reason, there is no restriction on the foot, and it is possible to eliminate the restriction of the arrangement of the foot controller 5 by the code and the remainder of the code at the time of foot operation.

  In addition, by changing the foot controller setting data 32, the setting of the content operated by the foot controller 5 can be arbitrarily changed.

  Further, since the wireless communication means 43 and 46 are provided as a plurality of receiving means, it is possible to prevent an operation signal from the foot controller 5 from being received due to a communication failure or the like and to realize a stable operation. In particular, since the wireless communication means 43 and 46 receive signals at different frequencies, wireless communication can be performed in the other frequency band even if there are jamming radio waves or the like in one frequency band.

  Further, since the foot controller 5 notifies the medical device 7 of the remaining battery level of the power source 54 detected by the remaining battery level detecting unit 54a, the foot controller 5 can notify the practitioner and the like that the remaining battery level is low. It is possible to charge or replace the power supply means 54 before it becomes impossible. Thereby, the stable movement of the operation control by the operation of the foot controller 5 can be realized.

  Further, when the remaining battery level is low, the drive control of the instrument 16 by the operation of the foot controller 5 is limited, so that the instrument 16 can be prevented from being unintentionally driven or stopped, and safety is improved. be able to.

  Moreover, since the power supply means 54 is a secondary battery and the connection terminal 56 is provided in the foot controller 5, it can charge easily even if the battery remaining of the power supply means 54 is insufficient.

  In addition, since the instrument detection means 26 of the holder 14 detects the insertion / removal of the instrument 16 and adopts an appropriate foot controller setting data 32 according to the detection, the practitioner does not have to switch manually. Appropriate operation control can be executed by operating the foot controller 5. Thereby, the smooth flow from the movement of the treatment chair 4 to the treatment can be realized, and the stress of the practitioner can be reduced.

  Further, since the executable operation items changed by the insertion and removal of the instrument 16 are displayed on the setting screen 80 of the display device 10 or the touch panel monitor 8a, the practitioner visually checks the items that can be operated with the foot controller 5 visually. Can be confirmed.

  In addition, since the practitioner can transfer the setting data customized and registered for himself / herself with one medical device 7A to another medical device 7B, the practitioner can perform medical treatment with the other medical device 7B in the same environment. it can.

  In addition, since the login user display unit 73 is provided on the main menu screen 70 and the setting screen 80 to display the logged-in practitioner, it is easy to determine which practitioner the medical apparatus 7 is operating for. It can be confirmed visually. Therefore, the practitioner can confirm whether or not the setting is for himself and operate the foot controller 5 or the like.

  In addition, the foot controller 5 can recognize that the wireless communication has failed if there is no response signal from the medical device 7 and also notify the fact so that it is prevented as much as possible from causing inconvenience to medical care due to the inability to wirelessly communicate. it can.

  In addition, since the foot controller setting data 32 registered in one medical device 7 can be transferred and registered to another medical device 7, the practitioner can share the operation contents of the foot controller 5 in different medical devices 7, and the same. It can be used conveniently in the environment.

  Further, the setting screen 80 can display the login user display unit 73 related to the medical operation using the instrument 16 and the computer operation on one screen, and thus can be used conveniently.

  In addition, since the foot controller setting data 32 can be registered by selecting from a plurality of pre-registered operation items, the foot controller setting data 32 can be customized with a simple operation.

  Further, since the operation items and operation contents of the instrument 16 by the operation of the foot controller 5 are stored in the storage means 41 (in the medical chair 4) of the medical device 7, an operation signal transmitted from the foot controller 5 is transmitted. It can be a simple signal such as ON / OFF of a switch.

  The foot pedal 5c of the foot controller 5 is configured to enable drive control according to the depression amount, but may be configured to transmit only an ON / OFF signal. In this case, drive control can be performed more easily.
