Description

[Detailed explanation of the idea] [Industrial application field]

This invention consists of a power supply box housing a power supply unit consisting of a control circuit, a transformer, etc., and a glass fiber rod containing a lamp and cooling fan at the tip for transmitting and irradiating light from the lamp. The dental visual aid is connected to the grip-type handpiece section to which the power supply box is attached, and can be carried stably with one hand while the handpiece section is suspended from the hanger of the power supply box body. This relates to a light irradiator.

[Conventional technology]

In recent years, photosensitive resins, which polymerize and harden when exposed to light, have been widely used in the dental field as dental prosthetic materials used to fill cavities, etc., in place of conventional dental alloys and dental cement. I've come to feel that way. Photosensitive resins used as dental prosthetic materials are often polymerized and hardened by direct irradiation with light in the human oral cavity, so they are exposed to ultraviolet rays that can have an adverse effect on the human body, and are exposed to heat that can harm the human body. A resin is used that is polymerized and cured by visible light without affecting infrared rays. A dental visible light irradiator for irradiating visible light onto such photosensitive resin has a power supply section consisting of a control circuit, a transformer, etc., a lamp, a cooling fan, etc. installed in one large box. One uses a pen holder-type hand piece that is made of long flexible glass fiber and serves as a light transmission and irradiation part attached to the box body, and the other uses only a power supply part that consists of a control circuit, transformer, etc. inside the box body. Some handpieces use a grip-type handpiece with a built-in lamp and cooling fan and a highly rigid glass fiber rod attached to the tip, which is connected to the power source with a cord. The hand piece parts of the dental visible light irradiator are all suspended or fixed to a hanger provided on the box body, and are carried by hand.

[Problem that the invention attempts to solve]

Among such dental visible light irradiators, those that use a grip-type handpiece have a built-in lamp and cooling fan in the handpiece and are separated from the power supply. This has the advantage that the power supply box can be made smaller, making the whole compact and easier for dentists to carry between treatment tables, but the power supply box with a built-in power supply is quite heavy. Therefore, if you try to transport the handpiece with one hand by suspending it from the hanger of the power supply box, it may fall off because the power supply box is made of smooth plastic material. There was a problem in that the dental visible light irradiator was easily damaged.

[Means to solve the problem]

Therefore, the inventor of the present invention made various studies to solve the above problems, and found that when the handpiece is suspended from the hanger provided on the upper side of the power supply box, the tip of the handpiece so that the glass fiber rod attached to the power supply box is stored in a state where it is approximately parallel to the upper surface of the power supply box, and the upper part of both sides of the power supply box that is substantially perpendicular to the side surface on which the hanger is provided. They discovered that it would be sufficient to provide a holding groove for gripping approximately parallel to the upper surface of the power supply box, and completed the dental visible light irradiator according to the present invention. That is, in the present invention, a glass fiber rod is attached to the tip of a hanger provided on the upper side of the power supply box, and a lamp and cooling fan are built inside, and the power supply box and cord are connected to each other. The dental visible light irradiator suspends the connected hand piece in a stored state in which the glass inbar rod is substantially parallel to the upper surface of the power supply box, To provide a visible light irradiator for dentistry, characterized in that holding grooves for gripping are provided in the upper portions of both sides substantially perpendicular to the side surface on which the hanger is provided, and are substantially parallel to the upper surface of the power supply unit box body. It is something.

[Configuration description]

Hereinafter, the dental visible light irradiator according to the present invention will be described in detail based on the embodiments shown in the drawings. FIG. 1 is a side view of one embodiment of the dental visible light irradiator according to the present invention, and FIG. 2 is a perspective view of the dental visible light irradiator in a gripping state. In the drawing, reference numeral 1 denotes a power supply box housing a control circuit, a transformer, etc., and its shape is generally a rectangular parallelepiped, but as in the illustrated embodiment, it is a box with a slightly expanded bottom. Various shapes such as a pyramidal shape can be adopted, and a hanger 2 is provided on the upper side of the shape, and the upper surface of the power supply unit box 1 is provided at the upper part of both sides substantially perpendicular to the side surface where the hanger 2 is provided. A holding groove 3 for gripping is provided substantially parallel to the holding groove 4 . The holding groove 3 preferably has a width of about 15 to 20 mm and a depth of about 1 to 5 mm. Reference numeral 5 denotes a handpiece portion having a glass fiber rod 8 attached to its tip and a lamp and a cooling fan built therein, and is connected to the power supply box 1 by a cord 9. This handpiece part 5 consists of a head 7 to which a glass fiber rod 8 is attached and a grip 6, and a hanger 2 of the power supply box 1.
When the handpiece section 5 is suspended, the glass fiber rod 8 becomes in a stored state in which it becomes substantially parallel to the upper surface 4 of the power supply section box body 1.

[Effect]

Next, a method of using the dental visible light irradiator according to the present invention having the above-described structure will be explained. In order to perform the work of polymerizing and curing dental prosthetic materials by irradiating visible light with visible light, the hand piece unit 5 is moved from the hanger 2 provided on the upper side of the power unit box 1.
is removed, the tip of the glass fiber rod 8 attached to the tip of the handpiece section 5 is directed toward the dental prosthetic material, and current is supplied to the handpiece section 5 from the power supply section box 1 to close the handpiece section. It is sufficient to turn on the lamp built in the fiber rod 5 and irradiate visible light from the tip of the fiber rod 8.
This operation is similar to that of a conventional dental visible light irradiator. When the use of the dental visible light irradiator according to the present invention is completed, the hand piece 5 is inserted into the hanger 2 provided on the upper side of the power supply box 1 from the grip 6 side. is suspended from the hanger 2 in a stored state in which the glass fiber rod 8 is approximately parallel to the upper surface 4 of the power supply box 1, and both sides of the power supply box 1 are substantially orthogonal to the side surface on which the hanger 2 is provided. A holding groove 3 for gripping is provided at the top of the surface substantially parallel to the upper surface 4 of the power supply box 1.
As shown in FIG. 2, grip the hand piece part 5 and the power supply part box body 1 from the top of the glass fiber rod 8 so that the thumb fits in one side and the index finger in the holding groove 3 on the other side. All you have to do is transport it to the location.

[Effect of the idea]

The dental visible light irradiator according to the present invention as described above has a glass fiber rod 8 attached to its tip, a lamp and a cooling fan built in, and is connected to a power supply box 1 by a cord 9. When the handpiece part 5 is suspended in a stored state from the hanger 2 provided on the upper side of the power supply box 1, the glass fiber rod 8 is approximately parallel to the upper surface 4 of the power supply box 1. A simple structure in which holding grooves 3 for gripping are provided approximately parallel to the upper surface 4 of the power supply unit box 1 at the upper part of both sides that are substantially orthogonal to the side surface on which the hanger 2 of the power supply unit box 1 is provided. As a result, it is a dental visible light irradiator that can be stably held and carried with one hand by integrating the handpiece part 5 and the power supply box body 1, and it is a dental visible light irradiator that can be held in an unstable grip state. This is of great practical value as it can prevent the phenomenon of objects falling and being damaged during transportation.
