{1. Embodiment}
FIG. 1 is an external view showing the entire medical training apparatus M according to the embodiment. FIG. 2 is a block diagram showing a configuration connected to the arithmetic processing unit 41 shown in FIG. The medical training apparatus M according to the present embodiment has a configuration suitable for performing simulated treatment training in the dental field. The medical training apparatus M includes a tray table 1 provided with medical instruments 11a to 11e, a pseudo-biological model 2 modeled on a human patient, and a medical treatment for performing medical treatment by fixing or placing the pseudo-biological model 2 A table 3 and an information processing device 4 that displays various information as a GUI (Graphical User Interface) and receives various commands to the pseudo-biological model 2 are provided.

  The tray table 1 is provided with a display unit 5 above the table 1a to call up and display a patient's chart and to monitor information related to practice such as operation contents of medical instruments during practice. It is possible.

  The tray table 1 includes an instrument holder 1b on the front side of a table 1a provided on the tray table 1 that is rotatably attached to the medical table 3 via an arm (not shown). Medical instruments 11a to 11e are attached to the instrument holder 1b so as to be picked up / stored. The instrument holder 1b may be provided on the medical table 3 as well as that provided on the tray table 1 as shown in FIG.

  The medical instruments 11a to 11e are driven upon detection of being picked up from the instrument holder 1b, are driven based on the operation of the foot controller 12, or are based on the operation of the operating means provided in the medical instruments themselves. Configured to be driven. The medical instruments 11a to 11e are appropriately connected to a water supply source, an air supply source, an air suction means, and the like. Various techniques including a known technique can be used for this connection mechanism.

  The medical instruments 11a to 11e correspond to cutting tools such as an air turbine handpiece and a micromotor handpiece, a scaler, a three-way syringe, and a vacuum syringe, for example. The medical instruments 11a to 11e are not limited to these, and may be an oral camera, a photopolymerization irradiator (none of which is shown), or the like. The operating state of these medical instruments is monitored by the medical instrument drive detection unit 111 provided in each of the medical instruments 11a to 11e or the tray table 1 and the like, and drive information of each medical instrument is collected in the information processing device 4. .

  For example, for a medical instrument having a rotation driving unit such as a tooth cutting medical instrument, the medical instrument drive detecting unit 111 acquires the rotation speed or a voltage value or a current value corresponding to the rotation speed as drive information. Further, as other driving information, an air pressure, an air flow rate, a frequency, a frequency, and the like when the medical instrument is operated may be acquired.

When the plurality of sensors 211a to 211d are simultaneously transmitted to the information processing apparatus 4, the detection signals from the respective sensors 211a to 211d are transmitted in a time division manner by the operation of the signal processing units 212a and 212b. By performing data communication with one signal line 24L, the wiring in the training part 21a and the connection between the connectors 214a and 221a can be simplified. Therefore, even if the number of sensors increases or decreases, it becomes possible to respond flexibly. Such a signal communication method using a single contact can be realized by applying a technology related to 1-Wire (a registered trademark of Maxim Integrated Products, Inc.), for example. The signal line 24L and the power supply line 26L may be shared by a single line.

  Note that instead of a single communication line, signal processing units 212a and 212b and signal lines extending from the information holding unit 213 are individually connected to the arithmetic processing unit 41 to transmit various signals in parallel. Good. In this case, although the number of pins between the connectors 214a and 221a is increased and the wiring is complicated, signals output from the respective units can be directly transmitted to the arithmetic processing unit 41.

In addition to the 1-Wire, the signal line for transmitting the electrical signals output from the information holding unit 213 and the signal processing units 212a and 212b to the information processing apparatus 4 is not limited to the above-described Controller Area Network. (CAN), Inter-Integrated Circuit (I ² C: registered trademark of Corning Crekka Philips Electronics NV) and related techniques related thereto can also be applied. When the CAN or I ² C technique is applied, it is configured to include at least two signal lines, a ground line, and a power supply line. Even using these techniques, it is possible to simplify the wiring in the training part 21a and the connection between the connectors 214a and 221a. Further, since the communication member is also inexpensive, the cost of the product can be reduced.

  The information holding unit 213 holds identification information assigned to the training part 21a and calibration information of the sensors 211a to 211d provided in the training part 21a. The pseudo-biological model 2 can be attached or exchanged with various types of training parts 21. The identification information is unique ID information assigned to each of the plurality of training parts 21 for each individual, and is used for specifying the individual of the training part 21 attached to the pseudo-biological model 2. . The identification information may be one that can identify only the type of the training part 21, but preferably the same kind of training part 21 can also be mutually identified.

  Here, as types of training parts 21, there are oral-related training parts 21 such as upper jaw parts 21A and 21D, lower jaw parts 21B and 21E, and tongue parts 21C described later. Of course, in addition to these, parts for training 21 that are modeled on otolaryngology, lips, etc., part 21 for training that is modeled on the presence of a diseased heart, lungs, etc. are provided with different attachment parts 22. May be.

  In addition, there are cases where a plurality of types of training parts 21 are prepared as models of the training parts 21, although they are attached to the same mounting part 22, and models each of the symptoms according to the training content. For example, in the training part for oral cavity, a training part 21 for simulating caries treatment, a training part 21 for simulating periodontal disease examination, and a training part for simulating implant treatment In addition to 21 and the like, a training part 21 that enables simulated training such as cavity formation, root canal cleaning, scaling, and the like may be attached to the same mounting site in a replaceable manner.

  In the present embodiment, identification information is assigned to each training part 21 in order to identify such various training parts 21 from each other.

  The calibration information is information for correcting the detection signals output from the sensors 211a to 211d. In general, a sensor may have different detection sensitivity or the like for each individual. Therefore, the arithmetic processing unit 41 corrects the detection signal based on the calibration information, thereby eliminating the individual error of the sensors 211a to 211d. The calibration information is not necessarily transmitted to the arithmetic processing unit 41. For example, the detection signals of the sensors 211a to 211d are calibrated by the signal processing units 212a and 212b, and then transmitted to the arithmetic processing unit 41. It may be.

  Thus, in this embodiment, it is comprised so that the arithmetic processing part 41 can acquire the calibration information of a sensor (treatment detection part 211) automatically according to the attached training part 21. FIG. For this reason, the operator can omit manual operations such as registering the calibration information for each training part 21 one by one every time it is mounted. Therefore, correction of detection information can be easily performed for each training part 21 and occurrence of human error can be suppressed.

  In the medical training device M, the connectors 214a and 221a are connected to each other and can communicate between the training part 21a and the information processing device 4, based on a read command output by the arithmetic processing unit 41. The identification information and the calibration information are read from the information holding unit 213 and output to the arithmetic processing unit 41. The arithmetic processing unit 41 performs the following operation according to the identification information and the calibration information.

  In other words, when the identification information is acquired, the arithmetic processing unit 41 identifies the attached training part 21 based on the part registration information stored in the storage unit 45, and the training part is mounted. Is notified to the operator via the display unit 42, or a corresponding training program is selected.

  In addition, when the calibration processing information is acquired, the arithmetic processing unit 41 uses this to correct the detection signals acquired by the sensors 211a to 211d as appropriate. When the calculation processing unit 41 stores the detection results of the sensors 211a to 211d in the storage unit 45, the detection information after correction may be stored, or the detection signal before correction may be used as it is. It may be stored so that the detection signal can be corrected thereafter using the calibration information.

  The power supply line 26L is a wiring for supplying power to the sensors 211a to 211d, the signal processing units 212a and 212b, and the information holding unit 213 provided in the training part 21a. A power source such as a battery may be mounted on the training part 21a itself. In this case, since it is not necessary to supply power from the pseudo-biological model 2, the power supply line 26L can be omitted.

  FIG. 5 is a partial side view showing an upper jaw part 21A, which is a specific example of the training part 21a, and an upper jaw mounting part 22A to which the upper jaw part 21A is mounted. In FIG. 5, a part of the upper jaw mounting site 22A is shown in cross section.

  The upper jaw part 21A is configured as an upper jaw model of a human body. The upper jaw part 21A includes a plurality of artificial teeth 210A mounted in a dental arch shape and a tooth cutting sensor 211A built in the vicinity of the base of the artificial tooth 210A. Further, the upper jaw part 21A connects the signal processing unit 212A that processes the signal sent from the tooth cutting sensor 211A, the information holding unit 213A that stores information about the upper jaw part 21A, and the upper jaw part 21A to the upper jaw attachment site 22A. And a connector 214A. Further, the upper jaw mounting portion 22A includes a part attachment portion 220A to which the upper jaw part 21A is attached and a connector 221A connected to the connector 214A.

  Some of the plurality of artificial teeth 210 </ b> A are treatment (treatment) objects in medical practice, and are formed as tooth models that simulate caries. The tooth cutting sensor 211A attached to the artificial tooth 210A is configured to detect a cutting situation (depth, position, etc.) when the artificial tooth 210A is cut by a medical instrument (cutting tool).

  In FIG. 3, only one tooth cutting sensor 211A is shown, but the tooth cutting sensors 211A may be attached to a plurality of artificial teeth 210A, respectively. Further, by attaching a pressure sensor, an impact sensor, or the like that detects a treatment other than cutting, the treatment content other than cutting may be detected. As a detection method of the tooth cutting sensor 211A, for example, a sensor that detects a change in electrical resistance or a sensor that detects vibration, pressure, light, temperature, or the like can be employed.

  As a method for fixing the upper jaw part 21A to the part mounting portion 220A, for example, it may be fixed by hooking a claw-like member provided on one of the parts to the other, or fixing a bolt member and a nut member or the like. It may be fixed by means, or a magnetic member such as a magnet may be attached and fixed by magnetic force. It is possible to employ an appropriate configuration that does not shift or come off during at least practical training and can be easily attached and detached.

  FIG. 6 is a block diagram showing an example of connection between the training part 21b and the simulated biological model 2. As shown in FIG. The training part 21b shown in FIG. 6 is a configuration example of the training part 21 and has substantially the same configuration as the training part 21a. However, instead of the connector 214a, transmission / reception is performed for wireless communication. Part 214b. The mounting part 22b on which the training part 21b is mounted includes a transmission / reception unit 221b that performs wireless communication with the transmission / reception unit 214b, and a mounting sensor 222. Elements having the same functions as those of the training part 21a shown in FIG.

  The transmission / reception unit 214b is connected to the signal processing units 212a and 212b. Detection signals output from the sensors 211a to 211d are processed by the signal processing units 212a and 212b and input to the transmission / reception unit 214b. The transmission / reception unit 214b is connected to the information holding unit 213, and can receive the identification information and the calibration information stored in the information holding unit 213. The transmission / reception unit 214b performs wireless communication with the transmission / reception unit 221b according to a predetermined communication protocol.

  The transmission / reception unit 221b is connected to the arithmetic processing unit 41, and outputs the detection signals of the sensors 211a to 211d transmitted from the transmission / reception unit 214b and the identification information or the calibration information stored in the information holding unit 213 to the arithmetic processing unit 41. To do. In addition, the transmission / reception unit 221b transfers the read signal from the arithmetic processing unit 41 to the transmission / reception unit 214b. As a result, various information stored in the information holding unit 213 is read.

  The mounting sensor 222b is connected to the arithmetic processing unit 41, and constitutes a mounting detection unit that detects whether or not the training part 21b is mounted on the mounting part 22b. The mounting sensor 222b is configured by an optical sensor, for example. Specifically, for example, by detecting the light that is emitted from the mounting sensor 222 and reflected by the training part 21b, the mounting of the training part 21b is detected. Further, it may be detected whether or not the optical path of the emitted light is blocked by mounting the training part 21b. Alternatively, the mounting sensor 222b may be configured by a pressure sensor to detect the pressure acting when the training part 21b is mounted. The mounting sensor 222b may be configured to detect a change in the amount of current in the circuit caused by the mounting of the training part 21b.

  The mounting sensor 222b may be provided on the training part 21b side. In this case, a signal indicating that it is attached may be transferred to the transmission / reception unit 221b via the transmission / reception unit 214b. Further, it may be detected that the training part 21b is mounted by detecting that the communication between the transmission / reception units 214b and 221b becomes possible. In such a case, the mounting sensor 222b can be omitted.

  Unlike the training part 21a shown in FIG. 3, the training part 21b shown in FIG. 6 performs wireless communication with the pseudo-biological model 2. For this reason, the signal line can be omitted, and the configuration of the connection portion can be simplified. As a configuration for performing wireless communication of identification information, for example, a technique such as RFID (Radio Frequency IDentification) can be used.

  FIG. 7 is a partial side view showing a lower jaw part 21B, which is a specific example of the training part 21b, and a lower jaw mounting part 22B to which the lower jaw part 21B is mounted. FIG. 8 is a top view of the lower jaw part 21B shown in FIG.

  The lower jaw part 21B is configured as a lower jaw model of a human body. The lower jaw part 21B is provided in the vicinity of the pharynx of the oral cavity, a plurality of artificial teeth 210B mounted in a dental arch shape, a periodontal pocket sensor 211Ba arranged in the periodontal pockets around the several artificial teeth 210B, and The impression sensor 211Bb is provided. The lower jaw part 21B includes a signal processing unit 212B that receives detection signals from the periodontal pocket sensor 211Ba and the impression sensor 211Bb, an information holding unit 213B that holds information about the lower jaw part 21B, and a transmission / reception unit 214B that transmits and receives signals. It has. The lower jaw mounting part 22B includes a parts mounting part 220B to which the lower jaw part 21B is attached, a transmission / reception part 221B for transmitting / receiving signals to / from the transmission / reception part 214B, and a mounting sensor 222B.

  In medical practice related to periodontal disease testing, a medical instrument (periodontal pocket measuring probe) is inserted into the periodontal pocket in order to measure the depth of the periodontal pocket. The periodontal pocket sensor 211Ba detects whether the depth of the periodontal pocket has been properly inspected. The periodontal pocket sensor 211Ba can be composed of a sensor that detects a change in electrical resistance, a sensor that detects pressure or light, and the like.

  The impression sensor 211Bb is provided at a position corresponding to the pharynx, and can detect the flow of the impression material used for collecting the tooth mold. In the example shown in FIG. 8, the impression sensor 211Bb is configured to use a plurality of (three) resistors and input these divided values to an A / D converter (not shown). However, the impression sensor 211Bb is not limited to the one that detects a change in electrical resistance, and can be configured by a sensor that detects pressure or light.

  In the above embodiment, the configuration of the periodontal pocket sensor 211Ba and the impression sensor 211Bb has been described by using the lower jaw part 21B and the lower jaw mounting part 22B. Needless to say, the upper jaw part 21A and the upper jaw mounting part 21B have the same configuration. It is desirable to do.

  The lower jaw part 21 </ b> B is a pseudo-biological model for effectively performing a medical training as to whether or not a periodontal disease test, impression acquisition, and occlusal acquisition can be appropriately performed. In this lower jaw part 21B, since wireless communication is performed between the transmission / reception units 214B and 221B, a signal line connecting the connection part of the lower jaw part 21B and the lower jaw attachment site 22B can be omitted, and the configuration can be simplified. it can.

  FIG. 9 is a top view showing a tongue part 21C which is one of the training parts. FIG. 10 is a side view showing the tongue part 21C and the tongue mounting part 22C shown in FIG. The outside of the tongue part 21C is made of an elastic material such as rubber, silicon, or a synthetic resin material, and a pressure sensor 211C, a signal processing unit 212C, an information holding unit 213C, and a connector 214C are included therein. Actuators 215 and 215 are provided. The tongue mounting part 22C is a part to which the tongue part 21C is mounted, and includes a connector 221C to which the connector 214C is connected.

  The pressure sensor 211C is formed in a sheet shape, and a plurality of pressure detection elements are arranged in a two-dimensional plane. The pressure sensor 211C and the signal processing unit 212C are connected by a signal line. The information holding unit 213C holds identification information about the tongue part 21C and calibration information about the pressure sensor 211C.

  The actuators 215 and 215 are connected to the arithmetic processing unit 41 via connectors 214C and 221C, and are driven and controlled based on a drive signal from the arithmetic processing unit 41. As the actuators 215 and 215, an electric type or a hydraulic type can be adopted.

  A plurality of signal lines extending from the signal processing unit 212C, the information holding unit 213C, and the actuators 215 and 215 are combined into one signal line and connected to the connector 214C in the same manner as the training part 21a shown in FIG. . At this time, the signal processing unit 212C, the information holding unit 213C, and the actuators 215 and 215 exchange signals with the arithmetic processing unit 41 through a single signal line. Note that signal lines extending from the signal processing unit 212C, the information holding unit 213C, and the actuators 215 and 215 may be connected to the arithmetic processing unit 41, and each signal may be individually input via a plurality of signal lines. .

  When the practitioner performs a treatment on the practicing part 21 in the oral cavity such as the lower jaw part 21B, the medical instrument or the hands of the practitioner may touch the tongue part 21C. The pressure sensor 211C detects contact with the surface of the tongue part 21C and outputs a detection signal to the signal processing unit 212C. The signal processing unit 212C transfers the detection signal to the arithmetic processing unit 41 via the connectors 214C and 221C. The arithmetic processing unit 41 outputs a drive signal for moving the tongue to the actuators 215 and 215 in accordance with the sent detection signal. Based on this drive signal, the actuators 215 and 215 can bend or swing the tongue part 21C in a predetermined direction, and retract or extend the front and rear and the left and right.

  In this way, by attaching the tongue part 21C to the pseudo-biological model 2, the tongue part 21C can be driven when a medical instrument or the like comes into contact with the tongue part 21C. Here, by setting the threshold value of the pressure required to drive the tongue to such a level that the actual patient feels uncomfortable, the drive of the tongue according to inappropriate contact can be realized. This makes it possible to reproduce a realistic medical practice, and can practice the medical practice with an awareness that the trainee does not touch the tongue inappropriately, so that the medical technique can be improved.

  In this embodiment, the connectors 214C and 221C transmit drive signals and detection signals in a wired manner. However, the transmission / reception units 214b and 221b as shown in FIG. 22C may be provided so that data communication can be performed by wireless communication.

  FIG. 11 is a side view showing the upper jaw part 21D and the lower jaw part 21E. The upper jaw part 21D and the lower jaw part 21E are training parts 21 formed for the purpose of performing a simulated practice of implant treatment for implanting an implant, and have a form in which a part of all normal teeth is missing. The upper jaw part 21D is attached to the upper jaw attachment part 22A shown in FIG. 5, and the lower jaw part 21E is attached to the lower jaw attachment part 22B shown in FIG. That is, the upper jaw parts 21A and 21D are configured to be detachable and replaceable with respect to the upper jaw mounting portion 22A. And the lower jaw parts 21B and 21E are comprised so that attachment or detachment is possible with respect to the lower jaw mounting part 22B.

  The upper jaw part 21D includes an implant sensor 211D, a signal processing unit 212D connected to the implant sensor 211D, an information holding unit 213D, and a connector 214D. The lower jaw part 21E includes an implant sensor 211E, a signal processing unit 212E, an information holding unit 213E, and a transmission / reception unit 214E.

  The implant sensor 211D is provided, for example, at the position of the maxillary sinus and is configured to detect whether the drill of the medical instrument has reached the maxillary sinus. The implant sensor 211E is provided, for example, at the position of the mandibular neural tube, and is configured to detect whether the drill of the medical instrument has reached the neural tube. Note that the positions where the implant sensors 211D and 211E are provided are not limited to these positions, and may be positions of other main neural tubes and blood vessels. Further, the implant sensors 211D and 211E can be configured by sensors that detect a change in electrical resistance, optical sensors, pressure sensors, or the like.

  The signal processing units 212D and 212E process the detection signals sent from the implant sensors 211D and 211E and transfer them to the arithmetic processing unit 41 via the connector 214D or the transmission / reception unit 214E. The information holding units 213D and 213E hold identification information about the upper jaw part 21D or the lower jaw part 21E and calibration information about the implant sensor 211D or the implant sensor 211E, respectively. The information holding units 213D and 213E transfer identification information and calibration information to the arithmetic processing unit 41 via the connector 214D or the transmission / reception unit 214E in accordance with a read command from the arithmetic processing unit 41.

  In addition, regarding the upper jaw part 21D, instead of the connector 214D and the connector 221A connected to the connector 214D, the transmission / reception units 214b and 221b shown in FIG. 6 are provided, whereby the signal processing unit 212D and the information holding unit 213D and the arithmetic processing unit 41 are provided. May be configured to perform wireless communication. Further, regarding the lower jaw part 21E, by providing the connectors 214a and 221a shown in FIG. 3 instead of the transmission / reception units 214E and 221B, the signal processing unit 212E and the information holding unit 213E and the arithmetic processing unit 41 perform wired communication. You may comprise as follows.

<Operation flow of medical training device M>
Next, the operation flow of the medical training apparatus M when the training part 21 is mounted on the mounting part 22 of the pseudo-biological model 2 will be described.

  FIG. 12 is a flowchart showing the operation of the medical training device M when the training part 21 is newly mounted on the mounting part 22. In addition, operation | movement of the medical training apparatus M demonstrated below shall be controlled by the arithmetic processing part 41 which performs a control program unless there is particular notice.

  First, the arithmetic processing unit 41 searches for identification information on a communication path (a communication line connecting the arithmetic processing unit 41 and the training part 21) (step S11). For example, when the user attaches the training part 21 a to the simulated biological model 2, the identification information is read from the information holding unit 213 a of the training part 21 a based on the read command from the calculation processing unit 41 and transmitted to the calculation processing unit 41. Is done.

  When the identification information is acquired, the arithmetic processing unit 41 determines whether or not the identification information is new (step S12). In the medical training apparatus M according to the present embodiment, identification information of training parts that are already mounted is sequentially registered in the storage unit 45 and the like as mounting part information. The mounting part information is data recorded by associating the mounting part 22 with the identification information of the training part 21 mounted on the mounting part 22. The arithmetic processing unit 41 determines whether or not the acquired identification information is new by referring to the mounted part information. Thereby, it is determined whether the training part specified from the acquired identification information is new. If it is not new identification information, the arithmetic processing unit 41 returns to step S11 again, continues to acquire new identification information, and monitors whether a new training part is mounted.

  In step S12, when the acquired identification information is new, the arithmetic processing unit 41 stores the new identification information in the storage unit 45 as mounting part information (step S13).

  Next, the arithmetic processing unit 41 identifies a corresponding training part from the newly acquired identification information, and displays that the training part is mounted on the display unit 42 (step S14). Alternatively, when a plurality of training parts of the same type such as teeth are densely mounted, if the display part 42 displays that the training parts are mounted and the mounted position, This is preferable because more detailed information can be notified to the user. In the present embodiment, since the display unit 42 is configured by a display, notification is made with a video. However, this notification method is not limited to video. For example, the display unit 42 may be configured as a means for outputting sound and may be displayed (notified) with sound.

  When it is detected at the time of notification in step S14 that the training part 21 for which the identification information has been acquired is mounted at a position different from the mounting part 22 that should be originally mounted, the display unit 42 A message may be displayed. Further, if the connection such as the connectors 214a and 221a shown in FIG. 4 is insufficiently connected and a failure such as communication interruption occurs, the attachment failure of the training part 21 may be notified. Further, in the case of the training part 21b shown in FIG. 6, when the mounting sensor 222b detects the mounting but cannot communicate between the transmission / reception units 214b and 221b, or can communicate but the mounting sensor 222b does not detect the mounting. And the like may be notified through the display unit 42 as a mounting failure.

  Next, the arithmetic processing unit 41 selects a training program corresponding to the specified training part from training programs prepared in advance (step S15). The arithmetic processing unit 41 refers to the part registration information stored in the storage unit 45 to identify the training program corresponding to the training part.

  When a plurality of training programs are selected in step S15, the arithmetic processing unit 41 may display a selection screen for selecting a training program on the display unit. Since the operator can select a target training program based on the selection screen, medical training can be performed efficiently.

  When there is only one training program to be selected, the arithmetic processing unit 41 may start the execution of the training program. Moreover, you may make it acquire approval of execution of this training program from an operator via the display part 42, the input part 43 grade | etc.,.

  If the operator attaches a training part 21 different from the training purpose to the simulated biological model 2, the arithmetic processing unit 41 notifies the operator of a training program that does not correspond to the training purpose via the display unit 42. It becomes. Therefore, the operator can recognize that the mounting is inappropriate by confirming this notification.

  FIG. 13 is a flowchart showing the operation of the medical training apparatus M when the training parts are removed from the simulated biological model 2. The medical training device M is configured to automatically detect whether the training parts have been removed, for example, by periodically executing the operation flow shown in FIG. Note that when the operator performs a predetermined operation input, an instruction to remove the training parts may be issued, and the medical training apparatus M may execute the operation flow shown in FIG.

  First, the arithmetic processing unit 41 searches for identification information on the signal path (step S21). Specifically, the arithmetic processing unit 41 acquires identification information from the information holding unit of training parts. This operation is almost the same as the operation in step S11.

  Next, the arithmetic processing unit 41 determines whether or not the registered identification information has been changed (step S22). Specifically, the arithmetic processing unit 41 compares the identification information acquired in step S21 with the mounted part information. The arithmetic processing unit 41 sequentially performs such comparison with respect to all the attachment sites 22. If the identification information registered in the registration information is not acquired for a specific mounting part 22, it is determined that the training part 21 has been removed from the mounting part 22. Further, when different identification information different from the registered identification information is acquired for a specific mounting part 22, the training part 21 attached to the mounting part is replaced with another training part 21. It is determined that In addition, when a new training part 21 is mounted on the mounting part 22 that has not been mounted, the operations after step S13 are executed.

  In step S22, when there is a change in the identification information, the arithmetic processing unit 41 updates the mounted part information for the changed identification information (step S23). Specifically, the arithmetic processing unit 41 deletes the corresponding identification information when the identification information cannot be acquired in step S22, and when the different identification information is acquired, the corresponding attachment part 22 is deleted. The identification information is updated to new identification information.

  The mounted part information is stored in the storage unit 45 as the attachment / detachment history of the training part 21. At this time, the contents of the medical training performed according to the training program (for example, the driving information acquired by the medical instrument drive detection unit 111, the driving information of the pseudo-biological model 2, and the treatment detection unit 211) together with the mounting part information And a part or all of the detection information obtained by the posture detection unit 311, the information on the practice table obtained by the imaging unit 64 and the sound collection unit 65, and the like. The In this way, the medical training device M can record the training part 21 used in the medical training and the training content performed using the training part 21 in association with each other.

  Further, the arithmetic processing unit 41 updates the mounted part information and notifies the operator through the display unit 42 that the mounted training part 21 has been changed (step S24). Thus, the operator can recognize that the training part has been removed or that the training part 21 has been replaced. Note that the display unit 42 may be configured as a means for outputting sound, and may be notified by voice that there has been a change, or may be notified by video and sound.

  In step S23 and S24, if the part has been replaced with another training part, as described in step S15, the arithmetic processing unit 41 selects the training program corresponding to the replacement training part 21. You may make it do. By displaying a selection screen for selecting a training program to be executed from the selected training programs on the display unit 42, medical training can be efficiently started after replacement of training parts. Can do.

  As described above, a plurality of types of training parts 21 different from each other can be attached to and detached from the specific mounting part 22, and various types of medical training apparatus M can be used without greatly changing the system. Medical training can be carried out. Moreover, the maintenance of the medical training apparatus M can be facilitated by making the training parts 21 detachable.

  Also in the conventional medical training device, when the training part is mounted on the pseudo-biological model, the operator performs an operation of notifying (registering) the medical training device that the training part has been mounted. This operation is completed by, for example, displaying a list of training parts that can be mounted on the biological model on the screen and selecting the training parts mounted from this list. However, when the types of training parts that can be mounted on the pseudo-biological model increase, it becomes complicated to specify the training parts that are mounted from the list, and a registration error is likely to occur. Also, when there are a plurality of training parts to be mounted at one time, the registration work becomes complicated and mistakes are likely to occur. On the other hand, since the medical training device M according to the present embodiment can automatically specify the worn training parts 21 based on the identification information, the registration work can be performed simply. In addition, the occurrence of registration mistakes can be effectively reduced. Therefore, medical training according to the purpose can be performed smoothly and efficiently in an appropriate training environment.

{2. Modification}
In order to prevent erroneous mounting of the training part 21 according to the above embodiment, the structure of the mounting portion and the connector shape may be unique to each mounting site 22. By configuring in this way, for example, when there are a plurality of training parts 21 that have similar shapes but have different mounting parts, such as the upper jaw part 21A and the lower jaw part 21B, erroneous mounting can be effectively prevented.

  Moreover, in the said embodiment, although the upper jaw part 21A and the lower jaw part 21B are comprised as a different body, these may be comprised as an integrated type. Moreover, you may comprise the upper jaw part 21A, the lower jaw part 21B, etc. according to a man, a woman, an adult, a dwarf, an elderly person, a narrow jaw, an opposite occlusion, etc., for example.

  9 and 10 is provided mainly for the purpose of reproducing the movement of the patient's tongue. However, instead of the tongue model 21C, a tongue model modeled on symptoms of tongue cancer, tongue coating, stomatitis of the tongue, etc. is prepared, and these are attached to the tongue mounting site 22C, so that the treatment specific to the tongue symptoms can be performed. Effective medical training can be performed effectively. Also, various tongue parts such as a large tongue, a small tongue, a long tongue or a short tongue, a thick tongue or a thin tongue, a wide tongue or a narrow tongue may be attached to the tongue mounting portion 22C.

  In addition, as the training parts 21, for example, chest models that are modeled on symptoms such as breast cancer, mastopathy, and mammary cysts are prepared, and each is attached to the chest mounting site, thereby palpating the chest and performing surgical treatment. It is possible to effectively carry out such mock training.

  Moreover, although the pseudo living body model 2 of the said embodiment is made into the model which modeled the whole patient's body, you may be comprised as a part of patient's body. Further, the pseudo-biological model 2 is not limited to a model of a patient having some symptoms, and may be a model of a healthy human body. Such a biological model is particularly useful when conducting medical training for the purpose of various examinations. Furthermore, the pseudo-biological model 2 is not limited to a model that uses a human as a model, and may be a model that uses an animal other than a human as a model. Such a living body model is useful in medical training for simulating medical treatment in the veterinary field.

Further, by configuring the information holding unit 213 with a nonvolatile memory such as an EEPROM (Electronically Erasable and Programmable Read Only Memory), data such as identification information and calibration information held by the information holding unit 213 can be appropriately rewritten. May be. In particular, when the information holding unit 213 is configured with an EEPROM, the information in the information holding unit 213 may be rewritten based on the control of the arithmetic processing unit 41. At this time, by applying known techniques such as 1-Wire, CAN, I ² C, etc., the inside of the training part 21a shown in FIG. 3 and the connection part of the training part 21a Wiring can be simplified and the number of sensors can be flexibly adjusted. Note that the information holding unit 213 is not limited to the EEPROM, and other storage means (flash memory or the like) can also be adopted.

  Further, a rewriting device for rewriting the information stored in the information holding unit 213 may be separately provided according to the form of the training part 21. For example, in the case of the training part 21a shown in FIG. 3, a rewriting device that rewrites data in the information holding unit 213 in a wired manner using the connector 214a can be employed. In the case of the training part 21b shown in FIG. 6, a rewriting device that rewrites information in the information holding unit 213 wirelessly using the transmission / reception unit 214b can be employed. If the configuration is such that identification information etc. of training parts can be rewritten or erased by GUI operation etc., for example, the dental training parts were replaced with those for impression taking from those for caries treatment Sometimes, it is possible to rewrite the information stored in the information holding unit 213 of the training parts by inputting the changed information through the GUI, so that the information can be easily updated with a simple communication form. Also played.

For the training part 21a, the above-described 1-Wire is used as a signal line for communication means between the sensors 211a to 211d, the signal processing units 212a and 212b, the information holding unit 213, and the connector 214a. This is desirable because the wiring in the training part 21a can be simplified. In addition, known techniques such as CAN and I ² C as described above can be used for the signal lines. The communication parts between the sensors 211a to 211d, the signal processing units 212a and 212b, the information holding unit 213, and the transmission / reception unit 214b of the training part 21b (see FIG. 6 to be described later) are similar in configuration to the training part 21a.
