(Prior art) At a dental training desk equipped with a patient's head model, when training is not to be performed, the head model is tilted down, and the rail attached to the desk is used to move it down to the depth below the table top. When storing the head model and conducting the training, pull out the head model from the back of the desk below the top of the desk to the front of the desk and stand vertically to position the head model in front of the desk and above the top board. And a dental training desk equipped with a head model position change device that can change the direction to the required direction, such as the front or the left and right sides, is Japanese Patent Publication No. 50-91.
It is proposed in No. 15. This training desk is convenient for storing the head model when not performing the training, and is also convenient in that the orientation of the head model can be changed to the required direction such as the front or the left and right side in the training. Because it does not have a torso model, it is difficult to perform learning that matches dental practice in practice,
There is difficulty in acquiring the positions and postures of the surgeon and assistant during medical treatment. In addition, since the head model cannot be turned between the supine position for conservative treatment and the standing position for prosthetic treatment, and it is not equipped with technical equipment, perform technical training using this training desk. Can not. It is necessary to set up a separate training table or training desk for technical training.

On the other hand, the support element simulating the backrest of the medical chair can adjust the inclination and the height with respect to the horizontal so that the medical training can be performed under the conditions that actually match the medical treatment for the patient sitting on the dental medical chair. Thus, a dental training apparatus in which a torso model is mounted on a base and a head model is mounted on the torso model is proposed in Japanese Patent Publication No. 55-42398. This training device is a special device that simulates a medical chair, and is limited to clinical training in a supine position.
There is no room for other dental training or training, and it cannot be used as a desk. If you need a desk, you need to set it up separately. The installation of such a dedicated device for a specific purpose is not only economical per se, but also disadvantageously increases the floor space required for dental training or training.

(Problems to be Solved by the Invention) In view of the above-mentioned difficulties in a conventional dental training desk or training device, the present invention provides a dental training desk with not only a head model but also a torso model so that dental care can be performed. In addition to enabling training under conditions that better match the actual conditions, increasing the suitability for dental training, the dental training desk for clinical use can also be used for training of prosthetic technicians who had previously set up a separate training table. In this way, the use of dental training desks has been diversified. Further, the floor space required for dental training or training is reduced by increasing the use of dental training desks.

(Means for Solving the Problems) The present invention for solving the above problems provides a dental training desk for medical treatment provided with a patient model for dental training, wherein the patient model is a head model, a trunk model, and a head model.

The tilt adjusting device 33 will be described with reference to a sectional view of FIG. 8 and an exploded perspective view of a main part of FIG.
The shaft support 3 of the support base 330 fixed by appropriate means
A support shaft 333 having a large-diameter portion 334, a small-diameter portion 335, and a radial step portion 336 is supported by 31 and 332 so as to be movable in the axial direction.
A rotary bearing 337 is rotatably inserted through the large-diameter portion 334 of the support shaft 333, and a ratchet wheel 339 is inserted through the small-diameter portion 335 so as to be movable in the axial direction. Radial row-shaped trapezoidal teeth 338 are engraved on the right end face of the rotary bearing 337 as well shown in FIG. Radial row-shaped trapezoidal teeth 340 corresponding to the trapezoidal teeth 338 are engraved on the left end face of the ratchet wheel 339, and a central concave part 341 on which a spring 343 is mounted on the opposite right end face.
And a plurality of pin insertion holes 342 into which the rotation prevention pins 344 are inserted.
Is provided. Further, a slide prevention collar 345 is fitted on the outer periphery of the ratchet wheel 339, and one end of the collar is provided with a rotating bearing 3.
The other end abuts on the shaft support 332, and the collar 345 prevents the rotary bearing from moving in the axial direction. Further, the rotation preventing pin 344 inserted into the pin insertion hole 342 of the ratchet wheel and the pin insertion hole of the shaft support portion 332 is fixed to the shaft support portion 332 by a set screw 346 to prevent the ratchet wheel 339 from rotating. I have. The spring 343 is mounted between the bottom surface of the central concave portion 341 of the ratchet and the shaft support 332 in a compressed state, and normally presses the ratchet 339 toward the rotary bearing 337. The tip of the small-diameter portion 335 of the support shaft 333 penetrates through the shaft support and protrudes outward.

To explain the operation of the tilt adjustment of the above configuration, the trapezoidal pawl teeth 340 of the ratchet wheel and the trapezoidal pawl teeth 338 of the rotary bearing that are normally pressed by the spring 343 mesh with each other,
In addition, since the ratchet wheel 339 is prevented from rotating by the rotation preventing pin as described above, the rotary bearing cannot rotate.
However, when the support shaft 333 is pressed to the right, it slides to the right, and the radial step portion 336 of the support shaft presses the ratchet against the force of the spring 343 and slides to the right. As a result, the engagement between the pawl teeth 338 of the rotary bearing and the pawl teeth 340 of the ratchet wheel is released, and the rotary bearing 337 is rotatable around the support shaft 333. In this state, the support receiver 34 fixed to the rotary bearing is tilted by a desired angle. Next, when the pressing force on the support shaft 333 is released, the ratchet wheel returns to the original position again by the elastic force of the spring 343, and the pawl teeth 338 and the pawl teeth 340 mesh with each other to lock the rotation of the rotary bearing.

The support receiver 34 fixedly connected to the rotary bearing by the above-described tilt adjusting device can be tilted and adjusted with respect to the fuselage model 3, so that the first arm is inserted into the hole 35 of the support receiver. The body can also be tilted forward and backward with respect to the fuselage model.

The rotation coupling part 54 that couples the second arm 52 to the first arm 51 so as to be tiltably adjustable is also the same except that the first arm 51 and the second arm 52 are coupled and fixed to the support table 330 and the rotation bearing 337, respectively. Has the same structure as the above-mentioned tilt adjusting device 33, and the axis of rotation also extends in the horizontal direction and in the shoulder width direction of the trunk. The pivotal joint 54 allows the head model 4 to be tilted forward and backward with respect to the body model 3, thereby turning the head model 4 between the supine position and the upright position. Of course, any other known tilt adjusting device may be used for the rotary connecting portion 54.

The head model 4 is attached to the attachment at the tip of the second arm. Various known head models can be appropriately used as the head model 4 according to the purpose. For this reason, it is desirable that the head model is detachable from the support. Also, the mounting member or the mounting portion of the head model with respect to the mounting member may be adjustable in tilt so that the head model can be tilted back and forth with respect to the support. In the above-described embodiment, the case where one rotation coupling portion that enables the head model to be tilted forward and backward is provided in the support body 5 has been described, but the face direction of the head model can be changed left and right. You may further add the rotation connection part which makes it.

(Effect of the Invention) In the present invention, the patient model equipped on the dental training desk for medical care includes not only the head model but also the torso model, and the torso model can be tiltably adjusted with respect to the horizontal. Practical training that better matches the actual situation can be performed, and training of the positions, postures, and movements of the operator and the assistant during medical treatment can be effectively performed.

Further, in the present invention, the support for connecting the head model to the torso model is provided with a rotary joint that can adjust the tilt of the head model back and forth with respect to the torso model. It can switch between a supine position for conservative treatment and an upright position for prosthetic treatment. The training desk is equipped with a micro-motor for technical use and a vacuum mouse for attaching and detaching a suction device for technical use. Therefore, the dental training desk according to the present invention can be used not only for clinical training but also for technical training, and the training desk can be used in many aspects.

In the present invention, the rigid model is slidable back and forth under the training table top, and the torso model is pulled out from below the top plate to the front of the desk as needed, and from the front of the desk to the bottom of the training table. The fact that it can be freely stored is advantageous in that the torso model does not hinder the use of the training desk in various aspects.
Furthermore, when the head model is detachably connected to the rigid body model, in addition to the advantage that an appropriate head model can be selected according to the purpose of the training, the body model is stored under the top plate of the desk Also, there is an advantage that the head model does not get in the way.

According to the present invention, since the dental training desk for medical treatment can be used in various aspects as described above, it is possible to greatly reduce the floor area required for dental training and training. Conventionally, technical training requires a training table or training desk separate from the dental training desk for medical care.However, according to the present invention, this is no longer necessary, and therefore a technical training room is provided separately from the medical training room. It is no longer necessary. Furthermore, when the training desk of the present invention is configured so that the trainee can use the desk from both the front side and the rear side of the training desk, the floor area can be further reduced.
