Description

[0001]
[Industrial application fields]
The present invention relates to a dental training apparatus for practicing dental treatment.
[0002]
BACKGROUND OF THE INVENTION
Regarding the dental training device, there are various types such as, for example, Japanese Utility Model Publication No. 57-22197 that proposes a treatment table simulator on which a head model is placed, and Japanese Utility Model Laid-Open No. 3-81971 that proposes improvement on the installation space of a dental training table. Proposals have been made so far.
[0003]
However, in dental treatments that require detailed manual skills, it is extremely important to learn the working posture, treatment operation, and treatment equipment depending on the treatment content, and even one of these is inappropriate. Despite being said to be lacking in qualification as a dentist if there are any points, until now, the practice content of dental practice practitioners has been photographed and recorded as moving images, and after treatment practice or during treatment practice Dental practice with a means that can analyze the posture of the practitioner, how to handle the equipment, work procedure, work content, work time, etc. in real time in comparison with the standard manual and correct inappropriate points The device does not exist and has not been proposed.
[0004]
Dental practice is usually practiced by 10 to 20 practitioners at the same time under the guidance of one professor, and the professor's guidance may not be sufficient for all practitioners. Therefore, if the contents of the practice are captured and recorded as a moving image as before, and this cannot be seen, this is not pointed out even if there is an inappropriate point in the posture or action of the practitioner. , May remain uncorrected. In addition, it is difficult to analyze the content of the practicum treatment by comparing it with the standard manual or the model treatment of the teacher.
[0005]
Furthermore, until now, since the practitioner cannot view the contents of his / her treatment practice as a moving image after the practice, the quality of posture, movement, etc. can be compared with the standard manual or model treatment image. Neither self-assessment nor self-correction based on this.
[0006]
For these reasons, not only is it difficult to learn dental treatment techniques efficiently, but there is also a problem that it is easy to leave individual differences that are bad for the acquisition techniques.
[0007]
OBJECT OF THE INVENTION
The present invention was made for the first time paying attention to the above points, capturing and recording the contents of dental treatment practice as a moving image, and comparing the contents of practice treatment with this image in real time after or during treatment practice, We propose a dental training device that enables analysis and the like.
[0008]

【Example】
Details of the dental training apparatus of the present invention will be described below with reference to the drawings of the embodiments. FIG. 1 is a side view showing a first embodiment of the dental training apparatus of the present invention, and FIG. 2 is a plan view for explaining a state in which a large number of training apparatuses of this embodiment are arranged in parallel (10 in the drawing). . FIG. 3 is a perspective view of a second embodiment of the dental training apparatus of the present invention. FIG. 4 shows an image projected on the monitor device in the dental training apparatus of the present invention. FIG. 5 is a system configuration diagram of the imaging camera, the image storage device, the monitor device, and their control devices. In each figure, the same code | symbol has shown the identical part.
[0010]
In the first embodiment shown in FIGS. 1 and 2, a medical table 2 is placed on a height-adjustable base 1, and a human chest model 5 is placed on the medical table 2. . Reference numeral 3 denotes a backrest of the medical table 2, and a headrest 4 is attached to the backrest 3 via support means 41 and 42. The support means 41 and 42 are configured to be tiltable. On the headrest 4, a head model 6 having a tooth and jaw model (not shown) is placed.
[0011]
A support pole 7 supports the dental lights 8 and 8 and the imaging camera 9. As the imaging camera 9, various imaging devices such as a small camera such as a CCD, a video camera, a Sachicon imaging device, or the like that convert an image into an electrical signal can be used. It is preferable to support the camera 9 so that the center line of the camera 9 is located above the median line of the tooth jaw model so that the imaging camera can evenly photograph the inside of the tooth jaw model. For this reason, you may make it attach to a ceiling or a wall instead of the fixed support by a support pole as shown in the figure.
[0012]
Reference numeral 11 denotes a therapeutic instrument such as a syringe or a handpiece that is mounted on the backrest 3 of the treatment table so that it can be taken out and stored. These may be provided with numerically displayed position marks or the like that are useful for learning the correct holding method and usage. A part or all of the treatment instrument may be stored in the tray 12 (see FIG. 2).
[0013]
The clinic 2 can adjust the height by operating the control pedal 100 to move the base 1 up and down, and the head model 6 on the headrest 4 of the clinic 2 is adjusted to the sitting height of the practitioner A. The position can be adjusted to the appropriate height. The adjusted height can be displayed by the scale of the height scale 101 attached to the base of the base 1. The height of the stool 13 on which the trainer A sits is also adjusted to the height of the above-mentioned head model, and is adjusted to a height at which the trainer A can most easily observe and treat the treatment site, and the adjustment value is a height scale. 131. Further, the stool can be finely adjusted in the front-rear direction, and the adjustment value can be displayed on the front-rear position scale 132. Of course, it is desirable for the stool 13 to be pivotable about its central axis.
[0014]
By adjusting the height of the examination table 2 and adjusting the height and front / rear position of the stool 13 on which the practitioner is seated, the practitioner's appropriateness in the treatment practice performed on the tooth and jaw model attached to the head model Posture is secured. Since the adjustment values of the height and the front / rear position can be objectively displayed and recorded on the scales of the scales 101, 131, and 132, it is possible to easily reproduce the posture or provide posture correction guidance. From this point of view, it is desirable to store the adjustment scale value of each scale as data also in an image storage for training described later.
[0015]
The state of treatment training of the trainer A is captured as a moving image by the imaging camera 9 and stored in an image storage device (not shown) such as a VTR or an optical disk. The stored image can be reproduced by the monitor device 15 installed on the training desk 14 to project the training practice status of the trainer A. The image can be projected simultaneously with the image storage, and the status of the training practice of the trainer A can be projected in real time, or can be projected in slow motion with a time delay during the therapy training. Of course, it can also be projected after treatment practice.
[0016]
Practitioner B who forms a pair with practitioner A standardizes the state of treatment practice of practitioner A in this reproduced image, that is, the posture of practitioner A, how to handle medical equipment, work procedure, work content, work time, etc. Analyze in comparison with the manual. In the standard manual, for example, the head axis of the handpiece when the front teeth are ground using a high-speed handpiece, the tilt angle of the body axis with respect to the teeth, the cutting direction, the time, etc. are shown. By comparing with the treatment status of the trainee A, it is possible to analyze and evaluate finely and objectively the performance of the trainer A for each unit operation.
[0017]
Such analysis and evaluation can be performed not only by comparison with a standard manual, but also by reproducing an image of a professor's exemplary treatment on a monitor device and analyzing and evaluating it. In this case, it is desirable that the model treatment image of the professor and the state of treatment practice of the trainer A are simultaneously projected on the monitor device. Moreover, such analysis and evaluation are not only performed by one of the practitioners who make a pair, but also can be analyzed and evaluated in collaboration with the practitioner A and practitioner B who form a pair after the practicum, Furthermore, professors can be added to such analysis and evaluation at any time. The monitoring device can be used not only for such analysis and evaluation, but also for example, in which a model treatment example is copied and the trainee A and the trainee B learn this.
[0018]
FIG. 4 shows an image of treatment practice projected on the monitor device. In the figure, 61 is a tooth and jaw model mounted on the head model 6. 1 and 2, 16 is a chair for the training desk 14, and 17 is a teacher's desk, which includes a video controller. As will be described later, the monitor device 15 or the teacher's monitor device can be variously used. An image can be projected.
[0019]
In the second embodiment of the dental training apparatus of the present invention shown in a perspective view in FIG. 3, the head model 6 provided with the tooth jaw model is integrated in the training desk 18 and the installation space for the dental training apparatus is provided. Can be saved significantly. The head model 6 protrudes substantially horizontally on the front surface 180 of the training desk 18, and the treatment instrument 11 such as a syringe or a handpiece is also taken out from the front surface 180 of the training desk 18 and is detachably mounted. The dental light 8 and the imaging camera 9 are attached to a support pole 7 standing on the side of the training desk 18. On the upper rear side of the desk 18, an image storage device 10 such as a VTR or an optical disk for storing a moving image taken by the imaging device 9 and a monitor device 15 for reproducing and projecting the stored image are installed.
[0020]
In the case of the second embodiment with the above configuration, it is difficult to analyze and evaluate the status of the training practice of the trainee in real time as in the case of the first embodiment, but the training practice was performed after the training practice. The practitioner himself / herself, other practitioners who make a pair, or both can jointly analyze and evaluate the reproduced image. You can also learn the image of the model treatment on the monitor device. The head model 6 installed on the front surface 180 of the training desk 18 may have a detachable structure so that it does not get in the way when an image is projected on the monitor device 15 or analyzed and evaluated.
[0021]
FIG. 5 shows an example of a system configuration of an imaging camera (small video camera), a camera controller, an image storage device (VTR), a monitor device, a changeover switch, a controller, etc. for an instructor and a professor. By the operation, it is possible to store an image and project it on a monitor device in various modes as described below.
[0022]
(1) An image captured by the imaging camera for the practitioner is stored in the VTR for the practitioner or is recorded in real time on the monitoring device for the practitioner.
(2) The above-mentioned image is stored in the teacher's VTR or projected onto the teacher's monitor device without being stored.
{Circle around (3)} Images of the model treatment and the like imaged by the imaging camera for the teacher are stored in the monitor device with or without being stored in the VTRs of the specific trainer (s) or all trainees.
(4) The image of the model treatment or the like stored in the VTR for the professor is displayed on the monitor device of a specific practitioner or all practitioners.
(5) The images taken by the imaging cameras of all the practitioners or a plurality of specific practitioners are simultaneously projected on the professor's monitor device by dividing the screen or sequentially and cyclically by the time-sharing method.
[0023]
The imaging camera and camera controller for the professor may be omitted. In this case, the projection of the above (2) cannot be performed, but the image of the exemplary treatment can be learned by the practitioner by the projection of the above (3). It should be noted that the images stored in the respective VTRs for the professor and each practitioner can be projected to the respective monitor devices without being operated by the above-described changeover switch, and can be projected by the operation of each VTR. It is preferable to keep it.
[0024]
As mentioned above, although the Example of the dental training apparatus of this invention was described in detail, various deformation | transformation are possible for these Examples in the range of this invention besides the already described modification. For example, in the case of the first embodiment described above, the chest model and the treatment table are omitted, the head model is directly attached to a vertically movable base, and the treatment instrument is stored in a separate movable table. It is also possible to modify the configuration so as to simplify the configuration and reduce the required space.
[0025]
【The invention's effect】
According to the present invention, it is possible to shoot and memorize a moving image of the situation of the training practice of the practitioner, so that the content of the treatment practice, that is, the posture of the practitioner, in real time after or during the treatment practice, It is possible to analyze and evaluate instrument handling, work procedures, work contents, work time, etc. by comparing with standard manuals and model treatment images. Based on this, an inappropriate posture, procedure, action, etc. can be corrected.
[0026]
Therefore, it is possible to efficiently acquire dental treatment techniques, unify the contents of the technique acquisition, and improve the level of technique acquisition. In particular, when a practitioner forms a pair and the other practitioner analyzes the moving image of the treatment practicum content of one practitioner, real-time analysis is possible, and analysis can be performed efficiently and objectively. Mutual enlightenment can be expected, and the effect of practical training will increase.
[0027]
Further, since the imaging camera is arranged above the midline of the head model, the imaging camera can evenly photograph the inside of the tooth model. In addition, the position of the treatment instrument relative to the denture model can be correctly recognized from the photographed image, and the treatment operation of the practitioner can be accurately evaluated.
