Further, the posture of the operation lever 61A is not limited to the oblique posture in which the operation portion 60A is raised as in the present embodiment, but may be designed in a horizontal posture or an oblique posture in which the operation portion 60A is lowered. In that case, a hole 42h may be provided at an appropriate position of the operation unit 60A so that the operation unit can be operated.

  In addition, the longitudinal direction intermediate portion of the operation lever 61B formed on the elongated member, more specifically, the elongated plate-like member, is located on the upper frame side plate portion 54B on the other side (the right side in FIGS. 2 and 7). It is supported via a support pin 62B so as to be swingable. For the same reason as described above, the hole through which the support pin 62B is inserted into the operation lever 61B is set larger than the diameter of the shaft portion of the support pin 62B, and smaller than the diameter of the head portion of the pin. It is preferable that the operation lever 61B can move somewhat with respect to the support pin 62B. Note that the support pin 62B and the upper frame side plate portion 54B are fixed to each other by screwing or by the support pin 62B being formed in the upper frame side plate portion 54B. The operation lever 61B has an oblique posture, and one end portion of the operation lever 61B extends obliquely upward and rearward of the upper frame side plate portion 54B (that is, toward the back of the head), and the other end portion of the operation lever 61B is The upper frame side plate portion 54B extends obliquely downward toward the front (that is, toward the upper jaw model 90B). One end of the operation lever 61B is the rear head of the head model 40 and extends toward the inside of the hole 42h, and an operation portion 60B is provided at the tip of one end of the operation lever 61B. By operating the operation unit 60B, the operation lever 61B is swung around the axis X3 supported by the support pin 62B. The operation lever 61B may be provided on the articulator lower frame portion 52A. The operation lever 61B can be provided in the articulator lower frame portion 52A in the same manner as the attachment to the articulator upper frame 52B. Further, the posture of the operation lever 61B is not limited to the oblique posture in which the operation portion 60B is raised as in the present embodiment, but may be designed in a horizontal posture or an oblique posture in which the operation portion 60B is lowered. In that case, a hole 42h may be provided at an appropriate position of the operation unit 60B so that the operation unit can be operated.

  As a configuration for releasing the fixation of the lower jaw model 90A and the upper jaw model 90B by the fixing unit by the operation by the operation units 60A and 60B, various configurations using a mechanical configuration, an electrical configuration, and the like can be assumed. In this embodiment, it is set as the structure provided with the detachment members 64A and 64B and the transmission mechanism parts 66A and 66B.

  First, a configuration for releasing the fixation of the lower jaw model 90A will be described. The detaching member 64A is a member that relatively moves the lower jaw model 90A away from the permanent magnet 57A as a fixed portion. More specifically, the detaching member 64A is a member formed by, for example, appropriately pressing a metal plate or the like. From the elongated plate-like detaching main body 64Aa and one side of the detaching main body 64Aa, for example. And a protruding protruding piece 64Ab. One end of the detachment main body 64Aa is swingably supported by the tip of the lower swing support piece 56A via a support shaft 65A. The hole through which the support shaft portion 65A is inserted in the separation main body portion 64Aa is set to be larger than the diameter of the shaft portion of the support shaft portion 65A and smaller than the diameter of the head portion of the support shaft portion 65A. It is preferable that the posture can be changed with respect to the support shaft portion 65A. This is to allow play to prevent the articulator 50 from acting (opening / closing operation) when the operating unit 60A is operated to release the lower jaw model 90A. The separation protrusion 64Ab extends from one side of the separation main body 64Aa to a position corresponding to the cutout 55Aa. The detaching member 64A moves between both positions where the other end (the left end in FIGS. 2 and 4) is relatively displaced up and down around the axis X2 supported by the support shaft 65A. It is possible. The state in which the other end portion of the detachment main body portion 64Aa is disposed relatively downward is the fixed maintenance position, and the state in which the other end portion of the detachment main body portion 64A is disposed relatively upward is the detachment position. The play is the same for the structure of the long hole 61Bh provided in the operation lever 61B for releasing the fixation of the upper frame model 90B described later.

  In a state where the detaching member 64A is in the fixed maintaining position, the detaching protrusion 64Ab is disposed in the notch 55Aa and is in contact with the lower jaw model 90A attracted by the permanent magnet 57A or in a position separated downward. It is in. Further, in a state where the detaching member 64A is in the detaching position, the detaching protrusion 64Ab is moved upward from the notch 55Aa and is in a position protruding above the upper surface of the base member 55A. Therefore, in a state where the detaching member 64A is in the fixed maintenance position, the state where the lower jaw model 90A is attracted by the permanent magnet 57A is maintained. When the detaching member 64A moves from the fixed maintenance position to the detaching position, the detaching protrusion 64Ab of the detaching member 64A presses the lower surface of the lower jaw model 90A to move the lower jaw model 90A upward. Thereby, the lower jaw model 90A is relatively distant from the permanent magnet 57A, and the lower jaw model 90A can be easily detached from the permanent magnet 57A. When the pressing force is greater than the magnetic attractive force, the lower jaw model 90A is detached from the base member 55A.

  The transmission mechanism 66A is configured to transmit the movement of the operation unit 60A as a force for moving the detaching member 64A from the fixed maintenance position to the detaching position.

  More specifically, the transmission mechanism portion 66A includes the operation lever 61A, and a connecting member 67A that connects the other end portion of the operation lever 61A and the other end portion of the detachable member 64A. Here, the connecting member 67A is configured by a metal wire, and one end thereof is connected to the connecting hole of the other end of the operation lever 61A, and the other end is formed at the other end of the detachable member 64A. Connected to the connecting hole. The connection between the connecting member 67A and the operation lever 61A and the detaching member 64A is preferably in a playable state, in other words, in a state in which the mutual posture and positional relationship between them can be changed. Here, the end portion of the connecting member 67A is bent in a C shape and hooked on the connecting hole, thereby establishing a connected state with play. Both ends of the connecting member are larger than the diameter of the connecting hole so as not to fall out of any connecting hole. In this embodiment, the connecting member 67A is provided by using the connecting hole, but in addition to this, the tip of the connecting member is sandwiched between the operation lever 61A or the detaching member 64A and the plate-like member, and does not fall off. Alternatively, a method of screwing the plate member to the operation lever 61A or the detachable member 64A, a method of welding the operation lever 61A or the detachable member 64A and the connecting member 67A, or the like may be used.

  Now, when detaching the jaw models 90A, 90B, the detachment operation is usually performed with the articulator 50 in the maximum open state. At this time, the length of the connecting member 67A is designed in a state where the base member 55A and the lower jaw model 90A are fixed (that is, the detachable member 64A is kept fixed). In the present embodiment, when the articulator 50 is in the maximum open state, the connecting member 67A is provided a little longer and the extra length is used as play. The design in which the operating lever 61A and the detachable member 64A are connected is preferable because this play functions as a safety mechanism. In this embodiment, the connecting member 67A is configured to have play. That is, even if the operation unit 60A is pressed, the detaching member 64A does not act immediately due to play, so that the lower jaw model 90A does not easily come off when the operation unit 60A is inadvertently touched, for example. . The form of the connecting member 67A is not limited to the form of the present embodiment, and may be a design free from play when the base member 55A and the lower jaw model 90A are fixed (that is, the detachable member 64A is fixed and maintained). In this case, the mandibular model 90A can be easily detached by a small operation on the operation unit 60A.

  In a state where the detaching member 64A is in the fixed maintenance position, the other end of the operation lever 61A is in an inclined posture pulled downward via the connecting member 67A (see FIG. 4). When the operation portion 60A is pushed down from this state, the other end portion of the operation lever 61A is lifted upward, and this movement is transmitted to the other end portion of the detaching member 64A via the connecting member 67A. As a result, the other end of the detaching member 64A is lifted upward, and the detaching member 64A moves to the detaching position. Thereby, the separation protrusion 64Ab pushes up the lower jaw model 90A upward to move away from the permanent magnet 57A. Thereby, the lower jaw model 90A can be easily removed.

  Further, after the above state, when the lower jaw model 90A is again attracted to the permanent magnet 57A, the lower jaw model 90A pushes down the separation protrusion 64Ab of the separation member 64A, so that the separation member 64A is positioned at the fixed maintenance position. Become. In this state, the other end of the operation lever 61A returns to the inclined posture pulled downward via the connecting member 67A (see FIG. 4). This state is maintained during practical training. Note that the posture of the operation lever 61A is not limited to the oblique posture in which one end of the operation portion 60A is raised as in the present embodiment, but the horizontal posture, the gently inclined posture, and the one end side with the operation portion 60A. It may be designed to have a lowered inclination posture.

  Next, a configuration for releasing the fixation of the upper jaw model 90B will be described. The detaching member 64B is a member that relatively moves the upper jaw model 90B away from the permanent magnet 57B as a fixed portion. More specifically, the detaching member 64B is a member formed by, for example, appropriately pressing a metal plate or the like. From the elongated main body 64Ba and one side of the detaching main body 64Ba, for example. And a protruding protruding piece 64Bb. The intermediate portion in the longitudinal direction of the detachment main body portion 64Ba is swingably supported by the tip end portion of the upper swing support piece 56B via the support shaft portion 65B. For the same reason as described above, the hole through which the support shaft portion 65B is inserted in the separation main body portion 64Ba is larger than the diameter of the shaft portion of the support shaft portion 65B, and is larger than the diameter of the head portion of the support shaft portion 65A. It is preferable that the detachable member 64B can be changed in posture with respect to the support shaft portion 65B. The support shaft portion 65B and the upper swing support piece 56B are in a fixed relationship with each other by screwing or by the support shaft portion 65B being formed in the upper swing support piece 56B. The separation protrusion 64Bb extends from one side of the separation main body portion 64Ba to a position corresponding to the cutout portion 55Ba. The detaching member 64B is centered on the shaft center X4 supported by the support shaft portion 65B, and its one end portion faces the outside of the articulator 50 and the other end portion faces the inside of the articulator 50. And is supported so as to be swingable. In particular, by swinging the detaching member 64B, one end of the detaching member 64B (the right end in FIGS. 2, 6, and 7) is relatively displaced up and down. The state where one end and the other end of the separation main body 64Ba are arranged in a horizontal state is the fixed maintenance position, and the state where the other end of the separation main body 64Ba is disposed relatively downward is the separation. Position.

  In a state where the detaching member 64B is in the fixed maintaining position, the detaching protrusion 64Bb is disposed in the notch 55Ba, and the position where the detaching member 64B contacts the upper jaw model 90B attracted by the permanent magnet 57B or the base member 55B is the upper. It is in a slightly upper position on the surface side in contact with the frame main body 53B. Further, in a state where the detaching member 64B is in the detaching position, the detaching protrusion 64Bb is moved downward from the notch 55Ba and is in a position protruding downward from the lower surface of the base member 55B. Therefore, in a state where the detaching member 64B is in the fixed maintenance position, the state where the upper jaw model 90B is attracted by the permanent magnet 57B is maintained. When the detaching member 64B moves from the fixed maintenance position to the detaching position, the detaching protrusion 64Bb of the detaching member 64B presses the upper surface of the upper jaw model 90B to move the upper jaw model 90B downward. Thereby, the upper jaw model 90B is relatively moved away from the permanent magnet 57B, and the upper jaw model 90B can be easily detached from the permanent magnet 57B. When the pressing force is greater than the magnetic attractive force, the upper jaw model 90B is detached from the base member 55B.

  The transmission mechanism 66B is configured to transmit the movement of the operation unit 60B as a force for moving the detaching member 64B from the fixed maintenance position to the detaching position.

  More specifically, the transmission mechanism portion 66B includes the operation lever 61B and a connecting pin 67B protruding from one end of the detaching member 64B. A long hole 61Bh along the longitudinal direction is formed at the other end of the operation lever 61B. The connecting pin 67B is formed as an elongated rod-like member that protrudes outward from one end of the detaching member 64B, and is formed in a shape that can be movably inserted along the longitudinal direction of the elongated hole 61Bh. . Then, the connecting pin 67B is inserted into the long hole 61Bh, whereby the other end portion of the operation lever 61B and one end portion of the detachable member 64B are connected in a state where the inclination can be transmitted to each other.

  In a state in which the detaching member 64B is in the fixed maintenance position, the other end of the operation lever 61B is in an inclined posture that is pushed downward via the connecting pin 67B (see the operation lever 61B indicated by a solid line in FIG. 6). . In this state, the connecting pin 67B is located near the other end of the operation lever 61B in the long hole 61Bh. When the operation unit 60B is pushed down from this state, the other end of the operation lever 61B is lifted upward. Then, due to the connecting structure of the connecting pin 67B and the long hole 61Bh, the connecting pin 67B moves in the long hole 61Bh toward the middle of the operation lever 61B, and one end of the detaching member 64B is lifted upward (in FIG. 6). (See the operation lever 61B indicated by a one-dot chain line). As a result, the detaching member 64B moves to the detaching position, and the detaching protrusion 64Bb pushes the upper jaw model 90B downward to move away from the permanent magnet 57B. As a result, the upper jaw model 90B can be easily removed. The connecting pin 67B is designed to have such a length as to move along the long hole 61Bh while maintaining the insertion state without detaching from the long hole 61Bh when moving in the long hole 61Bh.

  Further, after the above state, when the upper jaw model 90B is attracted to the permanent magnet 57B again, the upper jaw model 90B pushes up the separation protrusion 64Bb of the separation member 64B, so that the separation member 64B is positioned at the fixed maintenance position. Become. In this state, the other end portion of the operation lever 61B returns to the inclined posture pushed downward via the connecting pin 67B (see the operation lever 61B indicated by a solid line in FIG. 6). This state is maintained during practical training.

  According to the training model device 10 configured as described above, the operation units 60A and 60B that receive the operation of releasing the fixation of the lower jaw model 90A and the upper jaw model 90B by the permanent magnets 57A and 57B are portions other than the face of the head model 40. In this case, since it is provided in a portion that is concealed by the wig 43 in the occipital region, the appearance of the wig, flocking, artificial skin, etc. is removed while maintaining the face of the head model 40 as much as possible. Alternatively, the lower jaw model 90A and the upper jaw model 90B can be operated by remote operation without displacing or moving a part of the head model such as the face at the time of detachment of the jaw model as in the conventional head model. Easy to remove. Further, as a result of easily removing the lower jaw model 90A and the upper jaw model 90B in this way, it is difficult to apply an excessive force to the head model 40, the lower jaw model 90A, or the upper jaw model 90B itself. Therefore, it is desirable in handling each part and mechanism.

  In particular, in the configuration in which the driving mechanism for reproducing the facial expression or reaction is incorporated in the head model 40, those driving mechanisms are also incorporated in the vicinity of the articulator 50, and the permanent magnets 57A and 57B are attached to the permanent magnets 57A and 57B. On the other hand, it is difficult to insert a hand. Further, when the head model 40 is disassembled, the disassembled parts are likely to be worn. Therefore, as described above, providing the operation units 60A and 60B in a portion other than the face of the head model 40 has a great merit that the lower jaw model 90A and the upper jaw model 90B can be easily removed. The driving mechanism for reproducing facial expressions or reactions will not be described in detail in this application. In FIG. 2 etc., the drive mechanism is not shown.

  In addition, the operation units 60A and 60B are provided in a portion of the pseudo patient body 30 that is not exposed to the outside, more specifically, at the rear of the head model 40 and hidden behind the wig 43. Therefore, the operation units 60A and 60B can be provided in a place that is not easily noticeable and difficult to visually recognize from the outside. Thereby, careless operation by a practitioner or the like can be suppressed. Further, a realistic appearance close to a human can be maintained without deteriorating the appearance of the simulated patient body 30.

  Note that the operation units 60 </ b> A and 60 </ b> B may be provided at the rear portion of the head model 40 or a portion hidden by the wig 43. The rear part of the head model 40 includes a part other than the face 41 of the head model 40, that is, a part called the back of the head and the back of the ear, a tray recess, or the like. For example, the operation units 60 </ b> A and 60 </ b> B may be in a rear portion of the head model 40 and not hidden by the wig 43, such as a portion called a tray recess. Further, the operation units 60A and 60B may be provided on the back of the head model 40 from which the wig 43 is omitted, behind the ears, etc., and may be blindfolded by covering the hair of the wig 43.

  Since the operation units 60A and 60B are provided in the head model 40, the operator can easily operate the operation units 60A and 60B while observing the relationship between the articulator 50, the lower jaw model 90A, and the upper jaw model 90B. Can be operated. In addition, it is assumed that the operator stands in the vicinity of the head model 40 at the stage before, last, and after a series of medical training, and the operation units 60A and 60B are moved from each standing position. Since it is provided at an easily accessible position, the operator can easily remove the lower jaw model 90A and the upper jaw model 90B by operating the operation units 60A and 60B without performing a large movement.

  Further, since the permanent magnets 57A and 57B are used as the configuration of the fixing portion, and the magnetic plates 93A and 93B of the lower jaw model 90A and the upper jaw model 90B are attracted and fixed by the magnetic force of the permanent magnets 57A and 57B, the configuration is simple. The mandibular model 90A and the upper jaw model 90B can be fixed with a simple and simple work. In addition, you may use a magnetic body which can be attracted | sucked with a permanent magnet as another structure of a fixing | fixed part, and may provide a permanent magnet in the lower jaw model 90A and the upper jaw model 90B side.

  The operation units 60A and 60B are not necessarily provided in the head model 40, and may be provided in the trunk model 32, the left and right arm models 34, the left and right leg models 36, and the like. . When the operation part is provided in these parts, the back of the trunk model 32, the calf part lamp of the leg part model 36, the part hidden by the seat part 16, or the part hidden by clothes attached to the simulated patient body 30 Etc. are preferably provided.

  Further, as a configuration for releasing the fixing by the permanent magnets 57A and 57B as the fixing portions by operating the operation portions 60A and 60B, a configuration using the separation members 64A and 64B and the transmission mechanism portions 66A and 66B is adopted. Therefore, the detaching members 64A and 64B are moved by the force that moves the operation units 60A and 60B, and the permanent magnets 57A and 57B are moved away from the lower jaw model 90A and the upper jaw model 90B, and the lower jaw model 90A and the upper jaw model 90B are moved away from each other. Can be removed. Therefore, it is possible to realize a configuration in which the lower jaw model 90A and the upper jaw model 90B can be removed with a simple configuration without incorporating other actuators and the like.

  In the above-described embodiment, the lower jaw model 90A and the upper jaw model 90B are moved by the detaching members 64A and 64B. However, the fixing member is movably provided on the side of the articulator 50, and the fixing members are moved by the detaching members 64A and 64B. You may make it move.

  In addition, as a transmission mechanism part, the structure using wire-shaped members, such as a metal wire, the structure using the insertion structure of the connection pin 67B and the long hole 61Bh, and metal such as sheet metal as in the above embodiment The plate-like member is provided between the operating levers 61A and 61B and the detaching members 64A and 64B, and a differential mechanism is provided, or the operating levers 61A and 61B and the detaching members 64A and 64B are displaced relative to each other. A configuration in which a rubber material such as a rubber bush, which is hardly deformed to some extent, is interposed as a spacer between the operation levers 61A and 61B and the detaching members 64A and 64B. Etc. are assumed. In a configuration using a rubber material as a spacer, a long member, more specifically, a hole formed in an end portion of an operation lever formed in the elongated plate member is inserted through the rubber material. The one end of the detaching member is inserted and held. At this time, the inner diameter of the hole of the operating lever into which the one end of the detaching member is inserted is larger than the diameter of the one end of the detaching member, and the holding portion (at the hole of the operating lever) provided at the tip of the one end. The holding lever for inserting and holding one end of the detaching member is set smaller than the diameter of the detaching member, and the operation lever can change the posture with respect to the detaching member. More specifically, the operation lever is supported so as to be swingable with respect to the detachable member. For example, in the above embodiment, the long hole 61Bh of the operation lever 61B is formed in a circular hole having a diameter larger than the diameter of the connecting pin 67B, and a rubber bush, which is an annular rubber material, is attached to the circular hole. The connection pin 67B is fitted and held in the bush. Alternatively, the same connecting and holding method can be adopted for the operation lever 61A and the detaching member 64A.

  Of course, as a configuration for removing the lower jaw model 90A, a configuration using the insertion structure of the connecting pin 67B and the long hole 61Bh or the above-mentioned other configurations may be applied, and as a configuration for removing the upper jaw model 90B, You may apply the structure using wire-shaped members, such as a metal wire, and the said other structure. The wire-like member described above is not limited to metal. Various string members may be used as long as they have resistance to the detachment operation of the jaw models 90A and 90B. In the above-described embodiment, the wire-like member is provided with play. However, this play is a spring member that expands and contracts to some extent, such as a spring that is designed to be in a maximum extension state in the open state of the head model 40. Can also be realized.

  In particular, when the operation unit is provided in a torso model or the like that is a part different from the head model in the pseudo patient body, a wire that can be bent to some extent is used as at least a part of the transmission mechanism unit, and this is used for the pseudo patient. It is good to arrange along a trunk model of a body, or to arrange along a trunk model part, connecting a plurality of link mechanisms suitably. Thereby, an operation part can be easily arrange | positioned also in the place away from the articulator.

  In addition, although the operation units 60A and 60B have been described in the example of the push-down operation, a configuration in which the push-up operation is performed, a configuration in which the operation unit 60A and 60B are pushed or pulled in the horizontal direction, and a configuration in which the operation unit 60A and 60B are twisted in the horizontal direction may be employed. . Further, the operation unit may be composed of a plurality of parts, and the plurality of parts may be collected and held in one place.

  In addition, here, the operation units 60A and 60B are provided in different places, but may be provided in one place. In the embodiment, the operation units 60A and 60B are provided on the left side and the right side of the head model 40, respectively.

  Further, the permanent magnets 57A and 57B and the magnetic plates 93A and 93B do not need to be fixed to each other in direct contact with each other. For example, a bag-like member that reproduces the oral mucosa and forms the peripheral wall of the oral cavity is attached to the articulator 50, and the lower jaw model 90A and the upper jaw model 90B are attached to the permanent magnets 57A and 57B via the bag-like member. It may be configured to be adsorbed.

{Modification}
Various modifications will be described based on the above embodiment. In the following description, the same components as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted. In addition, although each modification below demonstrates centering on the modification regarding a lower jaw model, the same modification can be employ | adopted also about an upper jaw model.

  First, the fixing portion for fixing the lower jaw model 90A is not limited to the configuration using the permanent magnets 57A and 57B as described above.

  For example, in the first modification shown in FIG. 9, a locking member 154 that can be locked to the lower jaw model 190A is used as the fixing portion.

  More specifically, first, the magnetic plate 93A is omitted from the lower jaw model 190A. A fixed protrusion 194A protrudes from the surface of the lower jaw model 190A opposite to the side on which the teeth 92A are provided. A locking hole 194Ah is formed along the radial direction of the fixed protrusion 194A.

  Further, the permanent magnet 57A is omitted from the base member 155A. The base member 155A is formed with a fitting hole 155Ah into which the fixed protrusion 194A can be fitted. Further, the base member 155A is formed with a slide support hole 156Ah formed so as to extend from the outer periphery of the base member 155A over the fitting hole 155h.

  The locking member 154 is a long member that can move along the slide support hole 156Ah. Preferably, the distal end portion of the locking member 154 is gradually narrowed toward the distal end side. The locking member 154 is movably disposed between a fixed position disposed so as to cross the fitting hole 155Ah in the slide support hole 156Ah and a fixing release position retracted from the fitting hole 155Ah. Has been.

  Then, the lower jaw model 190A is placed on the base member 155A so that the fixed protrusion 194A is fitted into the fitting hole 155Ah in a state where the locking member 154 is retracted from the fitting hole 155h and disposed at the fixing release position. Arrange. In this state, the locking hole 194Ah is formed so as to be positioned on the extension of the slide support hole 156Ah. Then, when the locking member 154 is inserted into the insertion hole 155Ah and moved to the fixed position, the base end and the distal end of the locking member 154 are disposed in the slide support hole 156Ah. The locking member 154 is also locked to the locking hole 194Ah of the fixed protrusion 194A of the lower jaw model 90A. As a result, the fixed projection 194A is fitted into the fitting hole 155Ah so as to prevent it, and the lower jaw model 190A is fixed to the articulator 50. Further, in this state, when the locking member 154 is retracted from the fitting hole 155h, the locking state between the locking member 154 and the locking hole 194Ah of the fixed protrusion 194A of the lower jaw model 90A is released and fixed. The protrusion 194A can be removed from the fitting hole 155Ah so that the lower jaw model 90A can be removed. In other words, in this modification, the lower jaw model 90A can be fixed or removed by moving the locking member 154 in the manner of a heel and displacing the locking member 154 to a fixed position or a fixed release position.

  Also in this modification, the lower jaw is transmitted by transmitting the movement of the operation portion as a force for moving the locking member 154 between the fixed position and the fixed release position via the transmission mechanism portion, as in the above embodiment. The model 190A can be fixed and removed. As the transmission mechanism portion, various link configurations can be considered. For example, an operating piece 165A extending in the vertical direction and extending toward the base member 155A side is extended to a member corresponding to the detaching member 64A. The operating piece 165A is formed with a long hole 165Ah extending in an oblique direction, and the locking member 154 is formed with a protrusion 154a that is movably inserted into the long hole 165Ah. When the protrusion 154a moves through the long hole 165Ah by being displaced, it is possible to employ a configuration in which the protrusion 154a moves between the fixed position and the fixed release position.

  Also according to this modification, the same operation and effect as in the above embodiment can be obtained except for the effect of using a permanent magnet.

  Moreover, the structure which cancels | releases fixation of the lower jaw model 90A by a fixing | fixed part according to operation by operation part 60A, 60B is the structure released | released by transmitting the operation force with respect to operation part 60A, 60B like the said embodiment. Not limited to.

  For example, in the second modification shown in FIG. 10, the transmission mechanism 66A is omitted, and instead, a drive mechanism 266A that moves the detaching member 64A from the fixed maintaining position to the detaching position is provided. The drive mechanism portion 266A is an actuator such as an air cylinder, a hydraulic cylinder, and an electromagnetic actuator, and has a rod portion 266Aa that can be driven forward and backward. The drive mechanism portion 266A is attached to, for example, the lower frame side plate portion 54A on one side, and the tip end portion of the rod portion 266Aa is connected to the other end portion of the detaching member 64A via the connecting member 267A similar to the above embodiment. It is connected to. In this modification, the drive mechanism unit 266A is driven by the drive circuit 268A, and the drive circuit 268A is based on an operation signal that is an electrical signal corresponding to the operation of the switch unit 269A as the operation unit. The rod portion 266Aa is advanced and retracted.

  In this modified example, when the switch unit 269A is operated (for example, an ON operation), the drive circuit 268A retracts the rod unit 266Aa of the drive mechanism unit 266A based on an operation signal corresponding to the operation to the switch unit 269A, and detaches. The other end of the member 64A is lifted upward. Accordingly, as in the above embodiment, the detaching member 64A moves from the fixed maintenance position to the detaching position, the lower jaw model 90A is lifted with respect to the permanent magnet 57A, and the lower jaw model 90A can be easily removed. Further, when the switch portion 269A is operated (for example, an off operation), the drive circuit 268A advances the rod portion 266Aa of the drive mechanism portion 266A based on an operation signal corresponding to the operation, and the other end portion of the separation member 64A is moved. Press down. Thereby, as in the above embodiment, the detaching member 64A moves from the detaching position to the fixed maintaining position, and the state where the lower jaw model 90A is attracted and fixed to the permanent magnet 57A is maintained.

  According to the second modification, the drive circuit 268A can move the detaching member 64A from the fixed maintaining position to the detaching position based on an operation signal corresponding to an operation on the switch unit 269A serving as an operation unit. The drive circuit 268A and the switch unit 269A, or the drive circuit 268A and the drive circuit 268A are connected by an electric wiring material such as an electric wire. Wiring can be easily performed between the simulated patient body 30 and the tray table 12, the treatment table 14, or the information processing apparatus 20. In addition, an operation signal can be transmitted between the drive circuit 268A and the switch unit 269A by wireless communication. Therefore, the degree of freedom of installation of the switch unit 269A as the operation unit is excellent. For example, as described in the above embodiment, the switch unit 269A can be provided in the tray table 12, the medical table 14 or the information processing apparatus 20 in addition to the respective parts other than the face 41 in the simulated patient body 30. . The switch unit 269A may drive the drive mechanism unit 266A via a control unit such as the information processing apparatus 20. In this case, the information processing apparatus 20 includes an input device such as a keyboard and a mouse. The input unit 23 may be used as a switch unit.

  In addition, the structure which drives the drive mechanism part as an actuator according to operation of a switch part like this 2nd modification, and cancels | releases fixation of the lower jaw model 90A is applicable also to the said 1st modification. In this case, the drive mechanism unit may be provided so as to move the locking member 154 from the fixed position to the fixed release position.

  In the third modification shown in FIG. 11, the permanent magnet 57A is omitted, and an electromagnet 354A is incorporated in a base member 355A corresponding to the base member 55A. As the electromagnet 354A, a general configuration in which a coil wire is wound around a core can be used. The electromagnet 354A is switched between an excited state and a non-excited state by the drive circuit 368A, and the drive circuit 368A activates the electromagnet 354A based on an operation signal corresponding to an operation of the switch unit 369A as an operation unit. And the drive is switched to the non-excited state.

  In the third modified example, when the switch unit 369A is operated (for example, turned on), the electromagnet 354A maintains the excited state and maintains the state in which the lower jaw model 90A is attracted and fixed. Further, when the switch unit 369A is operated (for example, an off operation), the electromagnet 354A is switched to a non-excited state, and the lower jaw model 90A can be easily removed.

  According to the third modification, the switch unit 369A is excellent in installation flexibility for the same reason as described in the second modification. Further, since the lower jaw model 90A can be attracted and fixed to the electromagnet 354A by a magnetic force, the lower jaw model 90A can be easily attached and fixed, and can be easily attached.

  In addition, each structure demonstrated by each said embodiment and each modification can be suitably combined unless it mutually contradicts.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
