Description

[Detailed description of the invention] (Industrial application field) This invention is a medical lighting device (commonly known as a surgical light),
In particular, it relates to improvements in dental lighting devices.

(Prior Art) Generally, a surgical light supported by a hanger arm is placed above a dental treatment table, and the surgical light illuminates the oral cavity of a patient lying on the treatment table to perform treatment. It will be done. This surgical light consists of a container frame having a light source section approximately at the center of the curved inner surface, and a reflector plate attached to the divided area of the container frame, and the light reflected by the reflector is directed into the patient's oral cavity. Used to irradiate.

Recently, a mirror plate has been placed on a part of the front of the above vessel frame,
A system has also been developed and put into practical use that allows the patient to visually check the condition of the affected area using a real image projected on a mirror plate, thereby improving communication between the patient and the surgeon. Even in the case of a surgical light with a head plate, the original function of the surgical light must be maintained, so the head plate must be placed in front of the surgical light when in use, and moved out of the optical path of the irradiated light when not in use. Installed as possible.

(Problem to be solved by the invention) As mentioned above, the surgical lamp with mirror plate greatly contributes to improving communication between patients and surgeons, and its practical value has come to be highly evaluated. . However, even when not in use, the surface of the mirror plate is exposed near the surgical light, so when operating the surgical light, other instruments may hit the surface of the mirror plate and damage it, and dust may This dust easily adhered to the surface and sometimes fell onto the patient's face when the end plate was operated.

In addition, even when using a mirror plate, it is necessary to irradiate the affected area, but at this time, a portion of the irradiated light from around the mirror plate is directly irradiated to the patient's eyes, so this irradiated light can cause blinding. There were times when it became difficult to see one's own affected area reflected on the mirror plate.

Furthermore, there is a growing demand for patients to be able to simultaneously observe an X-ray image in addition to a real image of the affected area using a mirror plate.

The present invention was developed in view of the above, and it covers the surface of the end plate when not in use to prevent scratches and dust from adhering to it, and also alleviates or prevents irradiation to the patient's eyes when the end plate is in use. It is an object of the present invention to provide a new medical illumination device which allows observation of X-ray photographic film and the like at the same time.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be explained based on the attached embodiment diagrams. Fig. 1 is a perspective view showing an example of the medical lighting device of the present invention, Fig. 2 is a vertical sectional view taken along the line - - of Fig. 1, and Figs. 3 and 4 are views similar to Fig. 2 of other embodiments. It is.

That is, the medical lighting device of the present invention is a medical lighting device comprising a container frame 2 having a light source section 1 approximately at the center of the curved inner surface, and a reflector plate 3 attached to a partitioned area of the container frame 2. Attach frames 4, 4 to both sides of the container frame 2, and insert a mirror plate 5 between the frames 4, 4.
When the protective plate 6 is placed horizontally and the mirror plate 5 is arranged approximately at the center of the irradiated light beam and substantially perpendicular thereto, the protective plate 6 intersects the irradiated light while continuing to the mirror plate 5, while The gist is that the protective plate 6 covers the surface of the mirror plate 5 when the mirror plate 5 is stored in a position where it does not interfere with the irradiated light.

It is desirable that the protective plate 6 is made of a semi-transparent or non-transparent plate material so that when the mirror plate 5 is used, the transmission of irradiated light to the protective plate 6 is reduced or prevented. Furthermore, the protection plate 6 is made of a milky white plastic or glass semi-transparent plate material, and a film locking portion 61 capable of locking an X-ray film (dental X-ray photographing film, etc.) f is provided on the surface thereof. It is also possible to use it as a so-called film viewer that can see through the image of the film f that is locked and mounted on the locking portion 61.

In addition, the frames 4, 4 are attached to the container frame 2, but in order to be able to be attached to an existing frame, they are equipped with a locking (latching) attachment means as shown in the embodiment described later. What you do is convenient.

Furthermore, the reflecting plate 3 is formed by connecting a large number of small reflecting surfaces in the direction of its surface area and curved toward the light source section 1,
The light reflected by the reflector 3 has a wide luminous flux (without concentrating on one point) and can be applied to the affected area (for example, inside the mouth or vagina).
It is designed to be able to irradiate a wide area without creating shadows, and specifically, it was developed by Jikosho, the applicant's
The reflector plate etc. which constitute the dental operating light proposed in No. 48-45262 is preferably adopted.

(Function) In the medical lighting device having the above configuration, the light source section 1
The light emitted from the lamp is reflected by the reflecting plate 3, and this reflected indirect light is irradiated onto a treatment area (for example, inside the patient's mouth or vagina) located in front of the illumination device. and,
When the end plate 5 is manipulated to be positioned substantially at the center of the irradiated light beam and substantially perpendicular thereto, a real image of the irradiated treatment area is projected onto the end plate 5. Therefore, if the treatment site is within the orovaginal region, the patient can visually recognize it while maintaining the treatment posture.

At this time, the protective plate 6 is arranged so as to intersect with the irradiated light flux in a continuous state with the mirror plate 5, so if the protective plate 6 is made of a semi-transparent or non-transparent plate material, the protective plate 6 Transmission of the irradiated light is relaxed or blocked, and direct irradiation to the patient's eyes can be relaxed or blocked by appropriately selecting the relative position of the protective plate 6 and end plate 5.

In addition, if the protective plate 6 is made of a milky white semi-transparent plate material and a film locking portion 61 is provided on its surface, for example, a dental X-ray photographic film f can be attached to the film locking portion 61 when the mirror plate 5 is in use. When it is locked and mounted, the X-ray image of the film f can be viewed simultaneously by the light transmitted through the protection plate 6.
Therefore, by comparing the real image of the end plate 5 and the X-ray image taken on the X-ray film f, the patient himself/herself can accurately grasp the condition of the affected area, and the operator's explanation can be more accurately conveyed to the patient. will be done.

Then, by displacing and storing the mirror plate 5 in various manners as shown in the embodiments described later to a position where it does not interfere with the irradiation light, the irradiation light can be irradiated almost entirely on the affected area and used for the original treatment, In addition, the surface of the mirror plate 5 is covered with a protective plate 6, which prevents damage to the mirror plate, adhesion of dust, and unnecessary reflection of light from the mirror plate 5.
