It is a flowchart of the writing process in an IC tag writing device.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of an endoscope system to which a disposable treatment instrument management system according to an embodiment of the present invention is applied.

  In the present embodiment, the endoscope system 10 is an electronic endoscope system, and includes an endoscope apparatus including a scope 11 and a processor apparatus 12, and a monitor 13 connected to the processor apparatus 12. The scope 11 includes an insertion portion 14 made of a flexible tube, an operation portion 17 provided with an operation knob 15 and a forceps port (treatment tool insertion port) 16, and a universal cord that communicates between the operation portion 17 and the processor device 12. 18 is mainly composed of a connector portion 19 for detachably attaching the universal cord 18 to the processor device 12.

  In the processor device 12, for example, a light source unit 20 is provided. The light guide 21 disposed in the scope 11 is connected to the light source unit 20 via the connector unit 19. Light from the light source unit 20 is transmitted to the distal end of the insertion unit 14 via the light guide 21 and irradiated as illumination light. An imaging element (not shown) is provided at the distal end of the insertion unit 14, and an endoscope image is taken through the lens 22. The video signal from the image sensor is sent to the video processing unit 23 of the processor device 12 via the connector unit 19, subjected to predetermined image processing, and then output to an external device such as the monitor 13. Various processes in the processor device 12 are controlled by the controller 24.

  The scope 11 is provided with a forceps channel (treatment instrument insertion channel) 25 extending from the forceps opening 16 to the distal end of the insertion portion 14. Various types of treatment tools 26 including forceps are inserted into the forceps port 16, and the distal end 26 </ b> A of the treatment tool 26 extends from the distal end of the insertion portion 14 through the forceps channel 25. An operation unit 26B is provided on the proximal end side of the treatment instrument 26, and the distal end of the treatment instrument 26 is operated by operating the operation unit 26B.

  In the endoscope system 10, other than the disposable treatment tool is used. However, since only the disposable treatment tool is targeted in the disposable treatment tool management system of the present embodiment, the treatment tool 26 is a disposable treatment in the following. The case of tools will be described.

  In the present embodiment, in the disposable treatment instrument 26, for example, an IC tag 27 (for example, a passive IC tag) is embedded in the operation unit 26B, and an IC tag reader (reading device) is provided in the connector unit 19 of the scope 11. 28, for example, an RFID (Radio Frequency Identification) system is used. The IC tag 27 is provided with a flag indicating whether or not the treatment instrument 26 has been used. The content of the flag is read by the IC tag reader 28 in a non-contact manner when the operation unit 26B is brought close to the connector unit 19.

  The contents of the used flag read by the IC tag reader 28 are sent to the controller 24 of the processor device 12, for example. The controller 24 determines whether or not the disposable treatment instrument 26 has been used from the contents of the flag, and if it is determined that it has been used, warning processing is executed as described later.

  On the other hand, in the present embodiment, the contents of the flag of the IC tag 27 are rewritten by, for example, an IC tag writing device (IC tag writer) 29 provided separately from the endoscope device. That is, after the use of the disposable treatment instrument 26, the content of the used flag of the IC tag 27 is rewritten by the user holding the operation unit 26B over the IC tag writing device 29. The used flag of the IC tag 27 is set to “unused” (False) at the time of shipment, and a flag is set to be used by holding the IC tag 27 over the IC tag writing device 29 (True).

  Next, with reference to the flowchart of FIG. 2 in addition to FIG. 1, the used flag confirmation processing in the present embodiment will be described.

  For example, when the power of the processor device 12 is turned on in a state where the connector unit 19 and the monitor 13 are attached to the processor device 12, the used flag confirmation process of the present embodiment is executed centering on the controller 24. In step S100, initialization of the internal circuit including the processor device 12 and the connector unit 19 is performed, and output of the video signal to the monitor 13 is started in step S102.

  In step S104, it is determined whether or not a lamp switch (not shown) of the processor device 12 is turned on, and this determination is repeated until it is turned on. When the lamp switch is turned on, the lamp of the light source unit 20 is turned on in step S106, and it is determined whether or not the IC tag 27 is detected in step S108.

  If it is determined in step S108 that the IC tag 27 has not been detected, it is determined in step S120 whether or not the lamp switch has been turned off. If not, the process returns to step S108 and the same determination is repeated. It is. If it is determined in step S120 that the lamp switch has been turned off, the lamp of the light source unit 20 is turned off in step S122, and the process returns to step S104.

  On the other hand, when the operation unit 26B of the treatment instrument 26 is brought close to the IC tag reader 28 and the IC tag 27 is detected in step S108, the data of the IC tag 27 is read without contact by the IC tag reader (RFID reader) 28 in step S124. In step S126, it is determined whether or not the used flag is set (whether or not used). When the used flag is not set (in the case of False), the process returns to step S120 and the same process is repeated. On the other hand, if the used flag is set (in the case of True), an error code is sent from the IC tag reader 28 of the scope connector unit 19 to the controller 24 of the processor device 12 in step S128.

  Upon receiving the error code, the controller 24 generates a warning sound from the speaker 30 in step S130, and displays a warning on the monitor 13 in step S132, and the process returns to step S120. This process is repeatedly executed until, for example, the power of the processor device 12 is turned off.

  FIG. 3 shows an example of a monitor display on which a warning display is performed. For example, a message M: “Used product” indicating that it has been used is displayed in the lower right area of the screen S together with patient information, for example. . In other words, when the operation unit 26B of the disposable treatment instrument 26 for which the used flag is set is brought close to the connector unit 19, a warning sound and a warning display are made, and the disposable treatment instrument 26 is used and not used by the user. To warn. Note that the message is preferably displayed in a conspicuous form. For example, a warning color such as red may be used, or may be blinked.

  FIG. 4 is a flowchart for explaining the writing process of the IC tag writing device 29. Hereinafter, the writing process in the IC tag writing device 29 will be described with reference to FIGS.

  When the power of the IC tag writing device 29 is turned on, it is determined in step S200 whether or not the IC tag 27 has been detected. If not detected, the operation unit 26B of the treatment instrument 26 is brought close to the IC tag writing device 29, and the same processing is repeated until the IC tag 27 is detected. When the IC tag 27 is brought within a predetermined distance and the IC tag 27 is detected, the used flag is read from the IC tag 27 in step S202.

  In step S204, it is determined whether the treatment instrument 26 is unused based on the contents of the used flag. That is, if the used flag is not set (if False), it is determined to be unused, and if the flag is set (if True), it is determined to be used. If it is determined that it has been used, the process skips to step S210. If it is determined that it has not been used, the used flag write switch of the IC tag 27 is set to ON in step S206. It is determined whether or not.

  In step S206, when it is determined that the write switch of the IC tag 27 is on, the process proceeds to step S208, and the used flag of the IC tag 27 is set (the flag is rewritten to True). In step S210, it is determined whether or not the IC tag 27 is no longer detected. This determination is repeated until the disposable treatment instrument 26 is detached from the IC tag writing device 29 and the IC tag 27 is no longer detected, and when it is not detected, the process returns to step S200 and the same processing is repeated.

  On the other hand, when it is determined in step S206 that the used writing switch is in the OFF state, in step S212, the operation unit 26B is paradoxized and it is determined whether or not the IC tag 27 is not detected. If the IC tag 27 has not been detached and is still detected, the determination in step S206 is repeated. If the IC tag 27 has been detached and has not been detected, the processes in and after step S200 are repeated. The above processing is continued until the IC tag writing device is turned off.

  As described above, according to the disposable treatment tool management system of the present embodiment, prior to mounting the disposable treatment tool on the scope, the user holds the operation part of the treatment tool over the connector part, and the disposable treatment tool is used after use. By holding the IC tag writing device over the IC tag writing device, it is possible to prevent the used disposable treatment tool from being erroneously attached to the forceps channel.

  In this embodiment, the IC tag is provided in the operation part 26B of the treatment instrument 26 and the IC tag reader is provided in the connector part 19. However, as a modification, the IC tag is provided in the distal end part 26A of the treatment instrument 26, and the IC tag reader is provided. It may be provided in the vicinity of the forceps port 16 or in the operation unit 17. In this case, since the IC tag 27 is always brought close to the IC tag reader 28 prior to the insertion of the treatment instrument 26, a warning can be issued more reliably. Note that the IC tag reader 28 in the modified example is preferably arranged so that the forceps opening 16 is located within the readable range of the IC tag reader 28.

  In this embodiment, the IC tag writing device is provided separately from the endoscope device, but the IC tag writing device can also be incorporated into a processor device, for example. However, it is necessary to be sufficiently separated from the place where the unused treatment tool is placed before the treatment. In this embodiment, a warning sound is emitted and a warning is displayed on the monitor. However, either one of them may be used, or a warning lamp may be turned on or flashed instead of being displayed on the monitor. Good.
