BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dental suction hood device.

[0002]

2. Description of the Related Art In a dental clinic, treatments such as cutting teeth using an air turbine are performed. The dust generated during this cutting leaks out from the patient's mouth and floats in the room. Such dust is also a factor that impairs the health of dentists, dental hygienists, and other patients on the treatment table.

Therefore, recently, a suction hood is provided at the tip of a flexible suction duct, and the suction hood is brought to a position close to the mouth of a patient under treatment, and the dust is sucked from the suction hood. This significantly reduces the amount of dust floating in the room.

[0004]

When performing the above treatment, a shadowless lamp attached to the treatment table is used for facilitating the treatment, so that light is emitted into the oral cavity, which is the treatment site. Is irradiated.

However, in order to increase the dust suction efficiency of the suction hood, the suction hood must be brought close to the oral cavity, which often hinders the irradiation of the surgical light. Therefore, in order to prevent the treatment site from becoming dark, it is necessary to move the suction hood to a position where suction efficiency is poor or to frequently correct the position of the operating light.

An object of the present invention is to solve the above problems and to provide a dental suction hood device capable of avoiding darkening of a treatment site even at a position where the suction hood has the highest suction efficiency.

[0007]

According to the present invention, according to the present invention, a suction hood is attached to the tip of a flexible suction duct, and the suction hood has a transparent portion in at least a part thereof. This is achieved by arranging a light projecting device having a light source directed to the transparent portion at a rear position of the suction hood.

[0008]

In the present invention having such a structure, the suction hood is located at the position where the suction efficiency is the best, that is, near the treatment site,
And it is set facing in that direction. The suction hood has a transparent portion, and a light projecting device having a light source is provided behind it, and light from the light source passes through the transparent portion and irradiates the treatment site. Therefore, even if the light from the surgical light does not reach the treatment area during the treatment, the treatment area is sufficiently bright due to the light from the light source of the light projecting device and the treatment is not hindered.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 is a flexible suction duct, and pipe fittings 2 are provided at appropriate places including the tip portion thereof.
3 and 4 are provided. In the illustrated case, the pipe fittings 2, 3,
4 is adopted in three places, and two pipe joints that are adjacent to each other 2
And 3, and 3 and 4 are connected by a link arm mechanism 5, respectively. Each link arm mechanism 3 rotatably connects the two arms 7 and 7, one end of which is attached to the pipe joints 2 and 3 (and 3 and 4) by screws 6 or the like, to a desired rotation. And a screw member 8 for fixing it in the moving position. The central pipe joint 3 is divided at the central position, and the two split joints 3A and 3B are slidably fitted to each other so as to maintain arbitrary relative circumferential positions. Therefore, the two link arm mechanisms 5 and 5 can be positioned at 90 ° in the circumferential direction, for example, as shown in the figure by adjusting the relative circumferential positions of the split joints 3A and 3B. Thus, the tip of the suction duct (the position of the pipe joint 2) can be adjusted to any position in the three-dimensional space by adjusting the split joints 3A and 3B and the two link arm mechanisms.
The posture is set.

The pipe joint 2 attached to the tip end of the suction duct 1 is provided with a suction hood 9 which is conically opened forward. The suction hood 9 is made of a transparent material, and a lens-shaped condensing portion 10 extending in an annular shape is formed in the central portion in the axial direction. Further, a light projecting device 11 is attached to the pipe joint 2 so that the position of the pipe joint 2 can be adjusted so as to be adjustable in the axial direction.

The light projecting device 11 includes an annular holder 12 whose position can be adjusted on the pipe joint 2 as described above, and the holder 1.
A lamp 13 as a light source which is held at a plurality of positions in the circumferential direction by 2 and an umbrella-shaped reflector 14 which is attached to the back surface of the holder 12 and extends parallel to the suction hood 9 to a position in front of the lamp 13. Is equipped with.

In the apparatus of this embodiment, at the time of treatment, a dentist or the like turns on the lamp 13 and sets the position and the posture of the suction hood 9 in a state where the suction efficiency is the highest. That is, the suction hood 9 is oriented towards the treatment site of the patient. Therefore, the light of the lamp 13 is condensed by the condensing part 10 of the suction hood 9 and goes to the focal point 15. The light reflected by the reflector 14 is also focused on the focus 15. The dentist can irradiate the treatment site with light condensed in a desired radius range at a position slightly displaced from the focal point 15 in the axial direction. Thus, the light of the surgical light was conventionally blocked by the suction hood, but according to the present embodiment, the treatment area is illuminated by the light from the light projecting device 11.

The invention is not limited to the example shown. For example, the shape of the suction hood is not limited to a conical shape, and can be appropriately modified in consideration of light collection. Further, it is preferable that the entire suction hood is transparent, but only the light collecting portion may be transparent.
Further, the light projecting device may be provided on the suction hood in a variable position without being attached to the pipe joint. In any case,
It is preferable that the light projecting device be capable of adjusting the angle with respect to the axis. For that purpose, for example, a spherical portion for alignment may be formed on the holder. As the light source, not only a lamp but also an optical fiber can be used, and in that case, the direction of light projection can be adjusted more freely.

[0015]

As described above, according to the present invention, since the light projecting device is provided at the rear of the suction hood and the light can be applied to the treatment site through the condensing part of the suction hood, the suction hood has the highest suction efficiency. Even if the suction hood does not hit the light of the operating light when it is used in a good position / posture, it can be sufficiently supplemented by the floodlight device, and the treatment can be performed without any problems. Can be done.
