BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental treatment lighting device for illuminating the inside of the oral cavity for dental treatment.

[0002]

2. Description of the Related Art As a lighting device for illuminating the inside of the oral cavity for dental treatment, a single-light type lighting device and a two-light type unit-mounted lighting device have been conventionally used.

There are various types of single-light type lighting devices such as a ceiling hanging type, a stand pole type, a wall hanging type, and a chair mount type depending on the mounting method, but in short, a so-called shadowless lamp or the like is provided at the tip of the movable arm. The illuminating lamp is attached as a single light, and the operator adjusts the position and angle of the illuminating lamp to illuminate the oral cavity of the patient.

A two-lamp unit-mounted lighting device is equipped with two illuminating lamps whose positions and angles are adjusted so as to illuminate the oral cavity of a supine patient on the treatment table, and the arm is further treated. It is installed on a stand or pole stand. One lamp is adjusted to illuminate the upper jaw in the oral cavity and the other one is adjusted to illuminate the lower jaw. Since this unit-mounted lighting device is adjusted as described above, it can illuminate most of the usual dental treatment areas brightly, and in principle, it can be illuminated even if the patient changes or the treatment area in the oral cavity changes. It is a fixed type that does not adjust the position and angle of the light.

[0005]

In the single-light type illumination device, an operator or an assistant manually lights the illumination lamp every time the patient is changed, the treatment site is changed, the height or posture of the treatment table is changed, or adjustment is made. Since the position and angle of the must be adjusted, and the frequency of the adjustment is extremely high, the efficiency of the treatment work of the surgeon and the assistant is reduced, and fatigue may occur. Further, in order to operator or assistant touches the frequent hand lamp or the arm during the treatment, the illumination lamp or the arm is contaminated by pathogens like with the patient, the risk of infection occurs the operator or the like and interpatient is there.

In the case of a two-lamp type unit-mounted lighting lamp,
The adjustment of the position and angle of the illumination lamp is set for the intraoral treatment of the patient in the supine position, and it is not suitable for the intraoral illumination during the medical examination (interview, impression taking, occlusal practice, etc.) in the sitting position. , Separately, I need a single-lamp type lighting lamp for sitting position,
This illuminating lamp has the same problem as described above.

It is not possible to treat all oral cases in a supine position with two fixed lights. In some cases, appropriate lighting may not be obtained for special treatment areas,
There is a feeling that it is not possible to make fine adjustments during surgery. Also,
For example, when there is a significant difference in body length or body shape between adults and children, it may be inevitable to move the position of the patient's head according to the illumination because appropriate illumination cannot be obtained.

Further, in both the conventional single-light type lighting device and the conventional two-light type fixed lighting device, since the lighting lamp is located in a relatively low place and a place close to the patient, for example, the turbine is placed in the oral cavity of the patient. There is also a problem that it may be contaminated by splashes when pouring water in, and there is a problem that it is easy to touch with contaminated hands, and the illumination lamp and arm are in the patient's field of view, which is psychological to the patient, especially the child patient. There is a problem that the feeling of pressure is strong.

The present invention has been made in view of the above-mentioned points, and it is easy to adjust to appropriately illuminate an intraoral treatment site.
Moreover, it can be applied to special treatment areas that were difficult to handle with conventional equipment.
Even if it is properly illuminated, there is a risk of contamination by pathogenic bacteria.
It is an object of the present invention to provide a lighting device for dental treatment which is not rugged and does not give a patient a psychological pressure .
