Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a dental training desk equipped with a patient model consisting of a torso model and a head model.

(Conventional technology) When not practicing by placing a patient's head model on a dental training desk, the patient's head model is tilted downward and the top of the desk is placed on the desk using a rail attached to the desk. The head model is stored in the back of the lower part, and when practicing, the head model is placed from the back under the desk top to the front of the desk, and by standing vertically, the head model is placed in front of the desk and on the top. A dental training desk equipped with a head model position changing device located above the board and capable of changing its orientation to the front, left and right sides, etc., was developed by the Special Publication Publication No. 50-9.
No. 115 is proposed. This training desk is convenient for storing the head model when not practicing, and it is also convenient in that the orientation of the head model can be changed to the front, left and right sides, etc. when practicing. Since a model of the body is not provided, it is difficult to conduct learning that matches the actual practice of dental treatment, and it is difficult to learn the positions and postures of the surgeon and assistant during treatment.

On the other hand, the support element, which simulates the backrest of a dental chair, can adjust its tilt and height with respect to the horizontal, in order to enable clinical practice to be carried out under conditions that match the actual practice of treating patients seated in a dental chair. A dental training device in which a torso model is placed on the support element, and a head model is attached to the torso model is disclosed in Japanese Patent Publication No. 55-4239.
It is proposed in No. 8. This training device is a dedicated device that simulates a medical chair, and is limited to clinical practice in the supine position, so there is no room for it to be used for other dental practice or training.
It cannot also be used as a desk. 1. If a desk is required, it must be installed separately. Installing such specialized equipment for a specific purpose is not only uneconomical in itself, but also has the disadvantage of unnecessarily increasing the floor space required for dental training or training.

The screw is engaged in an arc-shaped curved groove 32 centered on the shaft 31, which enables the body 3 to tilt around the shaft 31, and the screw is tightened to press its tip against the bottom surface of the groove 32. By doing so, the fuselage model is fixed at a desired tilt angle. As means for making the fuselage model adjustable in tilt, various known tilt adjustment devices other than those described above can be used, and tilt adjustment means to be described later can also be used. In addition, in Fig. 4, 6 is the fuselage model 3.
There is an instrument such as a syringe attached to the shoulder of the person.

FIGS. 5 and 6 are a top view and a side view illustrating a support that connects the body model 3 and the head model 4. FIG. 33
is a tilting adjustment device attached to the torso model 3 so that the axis of tilting extends horizontally and in the shoulder width direction of the torso. This is of the same type as the tilt adjustment device described in Utility Model Publication No. 57-44990. Reference numeral 34 denotes a support receiver fixedly connected to a rotation bearing 337 (FIG. 8) of the tilting device, and has a hole 35 through which the first arm of the support 5 is inserted.

The support body 5 has a first arm 51 that is inserted into the hole 35 so as to be inserted into and removed from it and can be slidably adjusted, and a mount 53 at the tip.
The second arm 52 has a second arm 52, and a pivot joint 54 that connects the second arm to the first arm in a tilt-adjustable manner. As mentioned above, the thick plate-shaped first arm 51 inserted into the hole 35 of the support receiver 34 has a long groove 5 extending in the longitudinal direction of the arm.
10, the tip of the fixing screw 36 that is screwed into the tapped hole of the support receiver 34 engages in the long groove 510, and by tightening the screw 36, the tip of the screw presses the bottom of the long groove 510, The first arm 51 is fixed at a desired sliding position. Alternatively, the first arm may be fixed by fitting the tip of the screw into a fitting hole provided at the bottom of the long groove of the first arm.

The above-mentioned tilt adjustment device 33 will be explained with reference to the sectional view in FIG. 8 and the exploded perspective view of main parts in FIG.
A large diameter portion 334 and a small diameter portion 335 are attached to the shaft supports 331 and 332 of the support base 330, which are fixed to the support base 330 by appropriate means.
A support shaft 333 having a diameter stepped portion 336 is supported so as to be movable in the axial direction. A rotary bearing 337 is rotatably inserted into the large diameter portion 334 of the support shaft 333, and an electric train 339 is inserted into the small diameter portion 335 so as to be movable in the axial direction.

As best shown in FIG. 9, a radial row of trapezoidal claw teeth 338 are carved on the right end surface of the rotary bearing 337.

A radial row of trapezoidal claw teeth 340 corresponding to the trapezoidal claw teeth 338 described above are carved on the left end surface of the train 339, and a central recess 341 to which a spring 343 is attached and a rotation prevention pin are formed on the opposite right end surface. A plurality of pin insertion holes 342 into which pins 344 are inserted are provided. Further, a slide prevention collar 345 is fitted to the outer periphery of the train 339, one end of the collar abuts the end face of the rotation bearing 337, the other end abuts the shaft support 332, and the collar 345 allows the rotation bearing to move in the axial direction. In addition, the anti-rotation pin 344 inserted into the pin insertion hole 342 of the electric train and the pin insertion hole of the shaft support 332 is fixed to the shaft support 332 by a set screw 346, prevents it from rotating. The spring 343 is installed in a compressed state between the bottom surface of the central recess 341 of the train and the shaft support 332, and normally presses the train 339 toward the rotating bearing 337. The tip of the small diameter portion 335 of the support shaft 333 passes through the shaft support and is protruded outward, and a locking nut 347 is screwed into the threaded groove provided at the tip, and the support shaft 333 is pulled out to the left in the figure. is prevented from coming out. The support receiver 34 is coupled and fixed to a rotation bearing 337.

To explain the operation of tilt adjustment with the above configuration,
The trapezoidal pawl tooth 340 of the train, which is normally pressed by the spring 343, meshes with the trapezoidal pawl tooth 338 of the rotation bearing, and since the rotation of the train 339 is prevented by the rotation prevention pin as described above, the rotation bearing is Can't rotate. However, when the support shaft 333 is pressed to the right, it slides to the right and the radial stepped portion 336 of the support shaft is pressed against the spring 333.
Push the train against the force of 43 and slide it to the right,
Along with this, the pawl tooth 338 of the rotation bearing and the pawl tooth 340 of the train
The engagement with the 5 rotation bearing 337 is released and the support shaft 333
It can be rotated freely around. In this state, the support receiver 34 fixedly connected to the rotary bearing is tilted by a desired angle. Next, when the pressing force on the support shaft 333 is released, the electric train returns to its original position due to the elasticity of the spring 343, and the claw teeth 338 and the claw teeth 340 engage with each other, thereby locking the rotating bearing.

The support receiver 34, which is fixedly connected to the rotary bearing by the above-described tilt adjustment device, can be tilted freely 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 adjusted to tilt forward and backward relative to the torso model.

The rotational coupling portion 54 that connects the second arm 52 to the first arm 51 in a tilt-adjustable manner also connects the first arm 51 and the second arm 5 to the support base 330 and rotation bearing 337, respectively.
2 is connected and fixed, the above-mentioned tilt adjustment device 33
It has the same configuration as , and the axis of rotation also extends horizontally and in the shoulder width direction of the torso. The head model 5 can be tilted back and forth with respect to the body model by this rotation coupling part 54.

Of course, other known tilt adjustment devices may be used for the rotation coupling portion 54.

A head model 4 is attached to the mount at the tip of the second arm. As the head model 4, various known head models can be used as appropriate depending on the purpose. For this reason, it is desirable that the head model be detachable from the support. Further, the mount or the attachment portion of the head model to the mount may be tilt-adjustable, so that the head model can be tilted back and forth with respect to the support. In the above embodiment, a case is shown in which one rotation joint part is provided in the support body 5 to enable tilting adjustment of the head model back and forth, but the direction of the face of the head model can be changed from side to side. A rotational joint may also be added.

(Functions and Effects of the Invention) In the present invention, the patient model equipped on the training table includes not only a head model but also a torso model, which allows training to better match the actual practice of dentistry. It is also possible to effectively train the position and posture of the person and the assistant. Moreover, in the present invention, the torso model can be tilted horizontally and adjusted freely, and the support that connects the head model to the torso model can be slidably adjusted relative to the torso model. It is possible to adjust the height as appropriate, and it is also possible to simulate height adjustment by raising and lowering a treatment table in actual clinical practice, and this is compatible with the fact that the head model can be tilted with respect to the torso model. The height, position, front and rear inclination, etc. of the head model can be adjusted appropriately by tilting the head model. Therefore, the training desk of the present invention is significantly more suitable for dental training than the conventional training desk.

In the present invention, the torso model can be slid back and forth under the top plate of the training table, and the torso model can be pulled out from below the top plate to the front of the desk, or from the front of the desk to below the top plate, as necessary. The fact that it can be stored freely is advantageous in that the torso model does not become an obstacle when using the training table in many ways.

In this case, the head model is removably connected to the torso model, that is, the support that connects the head model to the torso model is removable to the torso model, or the head model is removably connected to the support. Being flexible has the advantage of being able to select an appropriate head model depending on the purpose of the training, and also has the advantage that the head model does not get in the way when storing the torso model under the desk top. be.

In the present invention, medical instruments such as various syringes are attached to the shoulders of the torso model or the front of the desk, so it is convenient to pull out and store the instruments during training, and the desk can be used for many lessons. It is also advantageous for use in training.

In this sense, it is more desirable to attach the instrument to the shoulder of the torso model than to attach it to the front of the desk.

Furthermore, in the present invention, the training table is equipped with a suction device for technicians and a micromotor for technicians necessary for practicing and practicing technical work for dental prosthesis. Since the training desk of the present invention can also be equipped with a light and other equipment used for technical work, the training table of the present invention can be used not only for dental treatment practice but also for training and practice of technical work. Conventionally, training and practice of technical work required a work table or work table separate from the medical practice desk, but according to the present invention, this is not necessary. Therefore, there is no need to provide a technical work training area separate from the medical practice room.

If the training desk of the present invention is used, as described above, it is possible to omit or reduce the installation of desks, work tables, training equipment, or training halls for dental training or training other than clinical training, so the overall cost is reduced. The effect of saving floor space is extremely large.

Further, in the present invention, the training desk can be configured so that two trainees can use the desk facing each other from the front and back of the desk, so that the space-saving effect can be further enhanced.
