  The medical instrument holder 23 includes a holder main body 231 that charges the cordless medical instrument 70 while holding the cordless medical instrument 70 at the charging position. The holder main body 231 is an accommodation space forming body in which an accommodation hole 233 that is a space for accommodating the cordless medical instrument 70 is formed. A power transmission circuit 83 is embedded in the inner surface (for example, the inner bottom surface 235) of the accommodation hole 233 to supply power for charging to the cordless medical instrument 70 in a contactless manner without using a metal contact or a connector. It is.

  Since this medical instrument holder 23 does not need to be provided with a metal contact or a connector for charging, the operation of cleaning or wiping the inner surface of the accommodation hole 233 can be easily performed. In addition, even if the chemical | medical agent used at the time of medical treatment penetrate | invades into the inside of the holder main body 231, the damage of the holder main body 231 can be suppressed by comprising the inside of the holder main body 231 with the resin material etc. which have chemical resistance.

  The accommodation hole 233 has a space shape larger than the diameter of the cordless medical instrument 70. The accommodation hole 233 is arranged so that the power transmission circuit 83 and the power feeding mechanism (the power receiving circuit 73 (see FIG. 5)) of the cordless medical instrument 70 are close to each other within a range where power can be transmitted. The instrument 70 is held.

  Note that the hole shape of the accommodation hole 233 is not required to match the outer shape of the specific cordless medical instrument 70.

  A screw hole 237 is formed in the upper part of the medical instrument holder 23. The medical instrument holder 23 is attached to the stay 25 by screwing the screw into the screw hole 237.

  FIG. 5 is a diagram illustrating an internal configuration of the medical unit 100 including the unit main body 10 and the cordless medical instrument 70. The unit body 10 includes a power source 11 that is a power supply source, a control circuit 13 that controls power supply and the like, and a notification mechanism 15 that notifies the completion of charging and notifies various errors. .

  The holder main body 231 provided in the unit main body 10 includes an identification circuit 81 that identifies the type of the cordless medical instrument 70 held by the holder main body 231 and power for supplying power to the cordless medical instrument 70. A power transmission circuit 83, a data transmission / reception circuit 85 that transmits and receives various data, and a foreign object detection circuit 87 that detects a foreign object in the accommodation hole 233 are provided.

  Furthermore, the cordless medical instrument 70 transmits / receives data to / from an identification tag 71 that stores and holds an identification code, a power receiving circuit 73 that receives power, and a storage battery 75 that includes a lithium ion battery, a nickel metal hydride battery, or the like. A data transmission / reception circuit 77 that performs charging, and a charge control circuit 79 that controls charging of the storage battery 75.

  The identification tag 71 and the identification circuit 81 of the holder main body 231 constitute an RFID (Radio Frequency IDentification) identification system. The identification tag 71 stores an identification code that identifies the type of the cordless medical instrument 70, and the identification circuit 81 reads the identification code in a non-contact manner, whereby the cordless medical care accommodated in the holder main body 231 is stored. The type of instrument 70 for use is specified.

  Note that the identification of the cordless medical instrument 70 is not performed by the RFID identification system, but may be realized by other wireless configurations. For example, the cordless medical instrument 70 may be provided with a transmission circuit for transmitting information identifying the type as a digital signal, and the digital signal may be received by the identification circuit 81 to identify the type. Further, for example, the identification tag 71 may be a barcode attached to the exterior of the cordless medical instrument, and the identification circuit 81 may include a barcode reader to specify the type.

  Based on the identification result, the control circuit 13 determines the charging conditions (charging voltage, charging current, charging time, and all or part of the charging method). Thereby, even if it does not determine a charging system manually, since it can charge on the conditions suitable for the kind of cordless medical instrument 70, the convenience of the medical unit 100 improves. Here, the charging method refers to various charging methods such as constant current charging, constant voltage charging, rapid charging, trickle charging and the like.

  The power transmission circuit 83 of the holder main body 231 generates magnetic flux by supplying current to the coil. The power receiving circuit 73 of the cordless medical instrument 70 generates a current by receiving the generated magnetic flux with a coil. In this way, the holder main body 231 supplies power to the cordless medical instrument 70 in a contactless manner. The supplied power is stored in the storage battery 75 via the charge control circuit 79.

  The data transmission / reception circuit 77 transmits / receives data to / from the data transmission / reception circuit 85 of the holder body 231 based on the control of the charging control circuit 79. For example, information on the remaining charge of the storage battery 75, information indicating that charging has been completed, and the like are transmitted from the data transmission / reception circuit 77 of the cordless medical instrument 70 to the data transmission / reception circuit 85 of the unit body 10.

  The foreign matter detection circuit 87 is a foreign matter in the accommodation hole 233 (for example, a metal member (clip, etc.), a metallic prosthesis (dental crown, bridge, etc.), a hot-melt resin (dental filler), etc.) Is detected. When such a foreign substance exists in the accommodation hole 233, the cordless medical instrument 70 cannot be appropriately held at an appropriate charging position, and charging efficiency may be deteriorated. Moreover, there is a possibility that the cordless medical instrument 70 may break down or the inside of the accommodation hole 233 may be damaged due to the heat generated by the foreign matter. The control circuit 13 is configured to stop the supply of power to the power transmission circuit 83 of the detected holder body 231 when the foreign object detection circuit 87 detects a foreign object.

  As a specific configuration of the foreign object detection circuit 87, for example, a technique described in JP-A-2002-34169 can be applied. Specifically, a charging control transistor that changes the charging load by ON / OFF control in a predetermined pattern at the start of power transmission is provided in the cordless medical instrument 70, and the load pattern is detected by a detection coil provided in the foreign object detection circuit 87. By detecting the change, the presence of a foreign object can be detected. Alternatively, the foreign object detection circuit 87 may detect the foreign object by monitoring the charging efficiency. Furthermore, application of other known configurations to the foreign object detection circuit 87 is not prevented.

  The power supply 11 is a power supply source that supplies power for charging the storage battery 75 of the cordless medical instrument 70. The power supplied from the power supply 11 is first transmitted to the control circuit 13. The control circuit 13 includes a selection circuit 131 that selects a power transmission circuit 83 that should transmit power among a plurality (six in this case) of the holder main bodies 231, and a remaining charge detection circuit 133 that detects the remaining charge of the storage battery 75. And a charging completion detection circuit 135 for detecting that the charging is completed.

  The remaining charge detection circuit 133 detects the remaining charge of the storage battery 75 from the remaining charge information of the storage battery 75 acquired via the data transmission / reception circuits 77 and 85. In the present embodiment, the control circuit 13 is a power transmission circuit of the holder main body 231 that holds the cordless medical instrument 70 having the smallest remaining charge based on the detection result of the remaining charge. 83 is configured to supply power. Thereby, since the cordless medical instrument 70 with the smallest remaining charge can be preferentially charged, the possibility that the treatment is interrupted due to the battery running out during use is reduced. In addition, as a method of roughly detecting the remaining charge of the storage battery 75, the amount of charge to the storage battery is estimated from the time from the start of charging to the current time and the amount of supplied power, and the remaining charge is estimated from the approximate result. , Etc. can also be taken.

  The charging completion detection circuit 135 operates the notification mechanism 15 based on the charging completion data received by the data transmission / reception circuit 85. The notification mechanism 15 visually notifies the surgeon that the charging of the cordless medical instrument 70 is completed by changing the lighting state of the lamp or changing the display content of the display. However, the notification mechanism 15 may make an audible notification to the operator, such as by sounding a buzzer. By providing such a notification mechanism 15, the convenience of the medical unit 100 is improved.

  The notification mechanism 15 may be provided anywhere on the unit body 10 such as one corner of the tray table 21. However, by providing the medical instrument holder 23 itself or in the vicinity thereof, the surgeon can more easily recognize that the charging of the cordless medical instrument 70 has been completed. In the present embodiment, the notification mechanism 15 is also used as an error notification device when an operation error occurs in the unit body 10.

<1.2. Charging operation>
6 and 7 are flowcharts of the charging operation in the unit main body 10. When the power is turned on to the unit main body 10, the unit main body 10 starts a charging operation for the cordless medical instrument 70, but the unit main body 10 ends all the operations when the power is turned off. Unless otherwise specified, the operation of the unit body 10 is controlled by the control circuit 13.

  The unit body 10 determines whether or not the cordless medical instrument 70 (HP) is detected in the holder body 231 (step S1). Specifically, the determination is made based on whether or not the identification code recorded in the identification tag 71 has been read by the identification circuit 81. If not detected (NO in step S1), the unit body 10 is in a standby state until the cordless medical instrument 70 is detected.

  When the cordless medical instrument 70 is detected (YES in step S1), the unit body 10 confirms whether the detected cordless medical instrument 70 has a communication function (data transmission / reception circuit 85). (Step S2). Specifically, it is determined whether or not the unit body 10 includes the data transmission / reception circuit 85 by specifying the type of the cordless medical instrument 70 based on the identification code acquired in step S1. Note that the presence or absence of a communication function may be determined by actually performing data communication.

  First, the case where it is determined in step S2 that the communication function is not provided (NO in step S2) will be described with reference to FIG. In this case, the control circuit 13 determines a charging condition suitable for the type of the specified cordless medical instrument 70 (step S3). Specifically, the charging voltage or charging current, the power transmission time, etc. are determined.

  When the charging condition is determined, the control circuit 13 supplies power to the power transmission circuit 83 provided in the holder main body 231 in which the cordless medical instrument 70 is detected in step S1. Thereby, power transmission is performed to the electric power receiving circuit 73, and charge of the storage battery 75 is started (step S4).

  Next, the unit body 10 checks whether another cordless medical instrument 70 is detected in the other holder body 231 (step S5). This operation is specifically the same as step S1.

  If another cordless medical instrument 70 is detected (YES in step S5), it is determined whether to give priority to charging of the detected one. Specifically, by comparing the remaining charge amounts of the cordless medical instrument 70 to be charged and the newly detected cordless medical instrument 70, the one having a smaller remaining charge amount, Judgment is given to give priority to charging. When charging the newly detected cordless medical instrument 70 is prioritized (YES in step S6), the unit body 10 stops the power transmission in step S4 (step S7).

  On the other hand, when no other cordless medical instrument 70 is detected (NO in step S5), or when charging of the newly detected cordless medical instrument 70 is not prioritized (step S6). In step S8, the unit body 10 confirms whether or not a foreign object is detected by the foreign object detection circuit 87. The foreign object detection in step S8 may be performed prior to the detection of the other cordless medical instrument 70 in step S5. Further, the foreign object detection operation in step S8 may be omitted as appropriate.

  When a foreign object is detected (YES in step S8), the unit body 10 stops power transmission in step S4 and notifies the operator that an error has occurred by the notification mechanism 15 (step S9). . On the other hand, when no foreign object is detected (NO in step S8), the unit body 10 checks whether or not the power transmission time determined in step S3 has elapsed (step S10). If it is determined that the power transmission time has not elapsed (NO in step S10), the process returns to step S4, and the subsequent operations are performed again while continuing power transmission.

  When the power transmission time has elapsed (YES in step S10), the unit body 10 completes the power transmission and notifies the operator that the charging has been completed by the notification mechanism 15 (step S11). Thus, the surgeon can know that the charging of the cordless medical instrument 70 has been completed. Here, instead of the elapse of the power transmission time, it may proceed to the power transmission completion and completion notification in step S11 by confirming that the storage battery 75 is fully charged by communication of the data transmission / reception circuits 77 and 85.

  Next, the case where it is determined in step S2 that the detected cordless medical instrument 70 has a communication function will be described with reference to FIG. In this case, the unit body 10 confirms whether the cordless medical instrument 70 is in a communicable state (step S12). When communication cannot be confirmed (NO in step S12), the control circuit 13 transmits power lower than normal charging power (step S13). As a result, it is possible to supply power that can be communicated to the cordless medical instrument 70 that cannot perform data communication because there is almost no remaining charge.

  Then, the unit body 10 confirms whether or not a predetermined time has elapsed since the start of power transmission (step S14). If it has not elapsed (NO in step S14), the process returns to step S13 to continue low-power transmission.

  If the predetermined time has elapsed (YES in step S14), the unit body 10 performs communication confirmation again (step S15). When the communication cannot be confirmed (NO in step S15), the unit body 10 performs error notification by the notification mechanism 15 (step S16). As a result, the surgeon is notified that communication cannot be performed for some reason, such as inadequate power reception due to the failure of the power receiving circuit 73 or inadequate communication due to the failure of the data transmission / reception circuit 77. When the error notification is performed, the unit main body 10 returns to step S1 and performs the subsequent operations again.

  On the other hand, when communication is possible (YES in step S12 or YES in step S15), the unit body 10 checks the remaining charge amount stored in the storage battery 75 (step S17). Specifically, the unit main body 10 requests the remaining charge information to the cordless medical instrument 70. Based on the remaining charge information acquired in this way, the remaining charge detection circuit 133 detects the remaining charge.

  When the remaining charge is confirmed, the unit body 10 determines the charging condition (step S18). Specifically, a charging voltage or charging current at the time of power transmission that is determined in advance for each type of the specified cordless medical instrument 70 is employed. And the unit main body 10 starts transmission of the electric power for charge based on the determined charging conditions (step S19).

  When power transmission is started, the unit body 10 checks whether or not a foreign object is detected by the foreign object detection circuit 87 (step S20). When a foreign object is detected (YES in step S20), the unit body 10 stops power transmission and performs an error notification by the notification mechanism 15 (step S21). Note that the foreign object detection operation in step S20 may be omitted as appropriate.

  If no foreign object is detected (NO in step S20), the unit body 10 confirms whether another cordless medical instrument 70 is detected in the other holder body 231 (step S22). If it is newly detected (YES in step S22), it is determined whether or not priority should be given to charging of the newly detected cordless medical instrument 70 (step S23).

  When giving priority to the charging of the newly detected cordless medical instrument 70 (YES in step S23), the unit body 10 stops power transmission in step S19 (step S24), proceeds to step S2, and newly A transition is made to a charging operation in which the detected cordless medical instrument 70 is charged. First, it is confirmed whether or not the newly detected cordless medical instrument 70 has a communication function.

  The operation of the unit body 10 from step S22 to step S24 is substantially the same as the operation from step S5 to step S7. Further, the detection of the foreign matter in step S20 may be executed after the operations in step S22 and step S23.

  When no other cordless medical instrument 70 is detected (NO in step S22), or when priority is not given to charging the newly detected cordless medical instrument 70 (NO in step S23), the unit The main body 10 determines whether or not the charging of the cordless medical instrument 70 to be charged is completed (step S25).

  If charging has not been completed (NO in step S25), the process returns to step S19 and the subsequent operations are performed again. When the charging is completed (YES in step S25), the unit body 10 stops power transmission and notifies the charging mechanism 15 that the charging is completed (step S26). Then, the unit body 10 proceeds to step S1 and waits until another cordless medical instrument 70 is detected. The above is a description of a series of charging operations by the unit main body 10.

<1.3. Effects of this embodiment>
According to the medical unit 100 according to the present embodiment, when the cordless medical instrument 70 is charged by a contact terminal in order to charge the cordless medical instrument 70 by a contactless charging method.
