Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to a dental lighting device, and particularly to a dental lighting device whose illumination angle can be controlled remotely.

(b) Conventional technology Dental lighting equipment (light) has traditionally been space line (
The lighting angle was adjusted manually. In addition, when performing dental treatment, if the practitioner is positioned to the right of the patient's head and the patient's head is in the 12 o'clock direction, from an angle of about 9:30 to 12:30,
The patient's mouth was accessed and treated, and the assistant was located to the left of the patient's head. During dental treatment, the practitioner holds turbine instruments, teeth, forceps, syringes, etc., and when adjusting the angle of the light, an assistant usually does this, but the illumination position of the light is adjusted to the angle desired by the practitioner. If this was not the case, the practitioner would temporarily stop the treatment and make adjustments.

(c) Problems to be solved by the invention As mentioned above, conventional dental lighting equipment is manual, so when adjusting the lighting angle, the practitioner instructs the assistant to make the adjustment. Basically, the assistant makes the adjustment, but since the assistant's eyes turn towards the light, the patient's oral cavity is left unattended, and the practitioner does not do it himself, so it is not necessarily adjusted to the desired angle of the practitioner. However, if the practitioner wishes to adjust the angle himself/herself, there is a problem in that the practitioner must temporarily stop the treatment and then adjust the angle. Also, it is fine if the light is within reach while sitting, but if it is not within reach, you will have to change from a sitting position to a half-waisted position to adjust the lighting, allowing for smooth treatment. It was difficult to continue.

In view of the above, an object of the present invention is to provide a dental lighting device that can adjust the illumination angle while continuing treatment.

(D) Means for Solving the Problems The dental lighting device of the present invention is provided with a lighting device above the chair whose lighting angle can be controlled remotely, and a lighting device provided on the side of the headrest of the chair. It is uniquely equipped with an operating section to remotely control the lighting angle of the tool.

(E) Function In this dental lighting device, when the practitioner or assistant operates the operating section on the side of the headrest while sitting, the illumination angle of the lighting device is changed in accordance with the operation.

(f) Examples The present invention will now be explained in more detail with reference to Examples.

FIG. 1 is a perspective view of a dental treatment apparatus in which the present invention is implemented. This dental treatment apparatus 1 includes a treatment table 2 and a lighting device 3.

The treatment table 2 includes a chair 5 with a headrest 4, a vacuum 6, a tip table 7. A bracket/throat table 8 is rotatably attached to the tip table 7 and on which a turbine, an engine drill, a sliway syringe, etc. are suspended. However, having these components is similar to a conventional treatment table.

This treatment table 2 is characterized in that an operating section (remote control unit) 9 is provided on the left side of the headrest 4. This operation section 9 is provided to adjust the illumination angle of the lighting device 3, and details will be described further later.

The lighting fixture 3 is provided above the treatment table 2, and consists of two lighting fixtures 3a and 3b connected to the ceiling in the vertical direction of the patient sitting on the chair 5 (the front-rear direction of the chair).

The upper lighting fixture 3a is attached to the ceiling in part 1.
0a and a rond part 11a whose length can be freely varied; a remote control electric part 12a controlled by operation of the operation part 9;
It further includes a light 13a. Lighting fixture 3b
are configured in exactly the same way.

The reason why the length of the rod 1la (llb) is variable is because the light 13a (13b) is suspended from the ceiling, so it can be freely expanded and contracted so that it can be easily replaced when the light bulb burns out. Moreover, since each clinic has a different ceiling height, this also makes it possible to easily adjust the positional relationship between the treatment table and the light.

The electric part 12a (12b) uses a remote control similar to that used in automatic military electric mirrors, and the angle of the light 13a (13b) can be changed vertically and horizontally by driving this electric part 12a (12b). .

FIG. 2 specifically shows the panel surface of the operating section, and also shows an electrical system for adjusting the angle of each light of the lighting devices 3a and 3b. The operating section 9 includes an angle switching switch/notch 14 having a lever 15, an upper lighting device 3a and a lower lighting device 3b.
A changeover switch 16 for changing the angle adjustment of the upper lighting fixture 3a, and a power switch 17 for the upper lighting fixture 3a,
It is equipped with a power switch 18 of b. The angle switching switch 14 switches the lighting fixture 3a (3) when the lever 15 is tilted to the right.
The illumination angle of the light 13a (13b) in b) is swung to the right, and conversely, when the lever 15 is operated to the left, the angle of the light 13a' (13b) is also swung to the left. Similarly, when the lever 15 is operated upward or downward, the angle of the light 13a (13b) is also swung up and down. Therefore, the angle of the light 13a (13b) can be changed horizontally and vertically by operating the operating lever 15 left and right or up and down by the practitioner or his assistant. A signal S1 indicating the position of the operating lever 15 from the angle changeover switch 14 is sent to the lighting fixture 3 to drive the electric part 12a (12b). Note that when the changeover switch 16 for the upper and lower lighting fixtures 3a and 3b is switched to the upper side U, the angle operation by the lever 15 is performed for the upper lighting fixture 3a according to the signal S2, and vice versa. When the switch 16 is switched to the lower part, the angle adjustment by operating the operating lever 15 is performed for the lower part lighting fixture 3b. Further, the power switches 17 and 18 are provided separately for the upper lighting fixture 13a and the lower lighting fixture 13b, respectively.
When both switches 17 and 18 are turned on, the lights 13a and 13b of both lighting fixtures 3a and 3b are turned on by signals S3 and S4, but when adjusting the angle, both lights are turned on. If it is difficult to adjust each light when the lights are closed, turn off either the switch 17 or 18, depending on whether the angle is adjusted by switching between the upper or lower lighting fixtures using the changeover switch 16. Adjustments can be made with the lights off.

Note 1. Treatment room side wall 6 negative room controller 19
are provided with knobs 20 for the upper and lower parts, respectively.
a, 20b, and the brightness of the lights 13a, 13b can be adjusted.

When performing treatment using the dental treatment device 1 described above, the practitioner sits on the right side of the headrest 4, the assistant sits on the left side of the headrest 4, and the practitioner sits on the headrest from 9:30 to 12:30. Treatment will be performed on the patient's oral cavity from this angle. This itself is not particularly different from the conventional one. When cutting the mandibular teeth, the practitioner continues the treatment work while holding the turbine in his right hand, and if he wishes to change the illumination angle, he operates the control lever 15 of the control unit 9 with his left hand while continuing the treatment. The angle can be adjusted freely.

In addition, when cutting the upper jaw, the practitioner holds the mirror in his left hand and the turbine in his right hand, so the assistant holds the vacuum 6 and operates the lever 15 of the operation part 9 without temporarily stopping the cutting and lights 13a, 13b. The angle can be adjusted.

For example, if the practitioner or assistant wishes to adjust only the angle of the light 13a of the upper lighting device 3a, turn on the upper power switch 17 and switch the selector switch 16 to the upper side, and then move the operating lever 15 to the light position. You will operate it in the direction you want it to move. Even if the patient's head moves up and down during the treatment process, as shown in FIG. 3, the angle of the light 13a can be adjusted by the motorized part 12a, so it can be easily adjusted to an appropriate angle in response to the head movement.

Of course, as shown in Fig. 4, even if the patient's head moves from side to side, the angle of the line 13a can be shifted within the range of a predetermined angle θ, so that the angle is still appropriate according to the movement of the patient's head. can be adjusted to

Furthermore, as shown in FIG. 5, the apparatus of this embodiment uses two lights 13a and 13b to illuminate the inside of the oral cavity from above and below, so that the upper and lower jaws can be easily seen.

Moreover, since the lighting devices 3a and 3b can be attached to the ceiling after the chair is installed, they can be installed at the desired position of each doctor. Furthermore, the light 13 of the lighting equipment in the upper part
By turning on the two lights 13b of the illumination device 13a and 13b at the same time, brighter illumination can be achieved because the lights are not blocked by the practitioner's head or the like and the lights intersect.

In addition, in the above embodiment, the lighting fixtures 3 are two lighting fixtures 3.
A and 3b are used, but the number is not limited to two, and one or several lighting devices may be installed. In addition, the lighting fixtures are connected to the ceiling, but are not limited to this; they may be attached to the side wall of the treatment room or held on a lighting stand set up with a support, and the lighting fixtures may be placed near the treatment table. You may also place a stand.

(g) Effects of the Invention According to the dental lighting device of the present invention, the practitioner can adjust the angle of the light of the lighting device by operating the operating unit with his or her left hand without having to give instructions to an assistant during treatment. In addition, the assistant can adjust the lighting angle by operating the operating unit in the same way, so the angle of the lighting equipment can be adjusted arbitrarily to make the treatment easier without stopping the treatment. It is extremely convenient and allows treatment work to proceed smoothly. Further, since the lighting device itself is not integrally formed with the treatment table, the lighting device can be positioned far away when, for example, X-rays are taken, and the lighting device does not interfere with the imaging.
