Description

本発明は歯科医院等で歯科治療を施す際に、歯牙の修復に使用する歯科用レジン等を硬化させる歯科用光重合器、特に、導光部より光が外部に漏れないように工夫を施した歯科用光重合器に関する。   The present invention provides a dental photopolymerizer that hardens a dental resin used for restoration of teeth when performing dental treatment at a dental clinic or the like. Relates to a dental photopolymerizer.

従来におけるこの種の歯科用光重合器は、例えば、特開平10−179613号公報に歯科用光重合器の照射構造が開示されている。この歯科用光重合器にあっては、LEDやハロゲンなどの該光重合器から発生する光重合用の光が、ファイバー、石英、プラスチック等のライトガイド(導光部)に導かれ、該導光部から導出される光によって治療部位である歯牙の修復部に詰められた歯科用レジンを硬化させるようにした発明である。
特開平10−179613号
A conventional dental photopolymerizer of this type is disclosed, for example, in Japanese Patent Application Laid-Open No. 10-179613 as an irradiation structure of a dental photopolymerizer. In this dental photopolymerizer, light for photopolymerization generated from the photopolymerizer such as LED and halogen is guided to a light guide (light guide) such as fiber, quartz, plastic, etc. It is an invention in which a dental resin packed in a restoration part of a tooth that is a treatment site is hardened by light derived from the light part.
JP 10-179613 A

ところで、前記した歯科用光重合器にあっては、歯牙の修復部まで光を導くための導光部はファイバー、石英、プラスチック等の透明または半透明な部材で形成されているため歯牙の修復部に可視光を照射している時に、導光部内での光の乱反射などにより前記反射光がドクターなどの施術者(以下施術者という)の視覚に入ることがあり、目が眩んで歯牙の修復作業に支障をきたすという問題があった。   By the way, in the above-mentioned dental photopolymerizer, the light guide part for guiding light to the tooth restoration part is formed of a transparent or translucent member such as fiber, quartz, plastic, etc., so that the tooth is restored. When the visible light is irradiated to the part, the reflected light may enter the vision of a doctor or other practitioner (hereinafter referred to as a practitioner) due to diffused reflection of light in the light guide unit, etc. There was a problem that the repair work was hindered.

詳しくは図6に示すように、本体1に導光部2(前記した特許公報では14)が設けられ、導光部2は照射部位に光を照射し易いように、また施術者が操作し易いように導光部2の先端部が屈曲している。   Specifically, as shown in FIG. 6, the main body 1 is provided with a light guide portion 2 (14 in the above-mentioned patent publication), and the light guide portion 2 is operated by a practitioner so that the irradiation site can be easily irradiated with light. The tip of the light guide 2 is bent so that it is easy.

従って、施術者が歯科用光重合器を操作して、歯牙の修復部に光を照射している時、可視光は照射X方向に照射されるが、前記透明または半透明な部材を使用している導光部の場合、光の乱反射により、施術者のY方向、すなわち施術者の視覚Aの方向に反射光が向かい施術者の視覚に入り、目をくらませて歯牙などの修復作業に支障をきたすという問題があった。   Therefore, when the practitioner operates the dental photopolymerizer and irradiates the restoration part of the tooth with light, visible light is irradiated in the irradiation X direction, but the transparent or translucent member is used. In the case of the light guide unit, the reflected light is directed in the Y direction of the practitioner, that is, in the direction of the practitioner's vision A due to diffused reflection of light, and enters the practitioner's sight. There was a problem of causing trouble.

また、光の乱反射を防止する方法として、前記導光部の外表面に黒色の被膜を施すことにより可視光が外部に漏れないようにするものもある。この方法によれば、光が黒色被膜に吸収されることにより、導光部先端からの光の導光率が低くなり、歯牙の修復部への所望の光が得られず、歯科用レジンを硬化させるのに時間が掛かる、また十分な光を得ようとするならば、供給する電流値を上げるなど無駄なエネルギーを要することとなっていた。   Further, as a method for preventing irregular reflection of light, there is a method for preventing visible light from leaking to the outside by applying a black coating on the outer surface of the light guide section. According to this method, the light is absorbed by the black coating, so that the light guide rate of the light from the tip of the light guide part is lowered, and the desired light to the restoration part of the tooth cannot be obtained. It takes time to cure, and if sufficient light is to be obtained, useless energy is required, such as increasing the current value to be supplied.

さらには、歯科用光重合器を使用している最中や持ち運びなどの際に、本体に導光部を取付けて使用しているが、本体に装着した状態または導光部のみを床などに落下させた場合に、導光部を保護する部材がないために、該導光部が破損するという問題もあった。   Furthermore, while using a dental photopolymerizer or when carrying it, the light guide is attached to the main body, but it is attached to the main body or only the light guide is on the floor. When dropped, there is also a problem that the light guide part is damaged because there is no member for protecting the light guide part.

本発明は前記した問題を解決せんとするもので、その目的とするところは、透明または半透明な部材を使用している歯科用光重合器の導光部から漏れる反射光を防止し、施術者の目に入らないようにし歯牙の修復作業に支障をきたさないようにするとともに、また導光部を床などに落下させても容易に破損しないようにした歯科用光重合器を提供せんとするにある。   The present invention is intended to solve the above-described problems, and the object of the present invention is to prevent reflected light leaking from the light guide part of a dental photopolymerizer using a transparent or translucent member, and perform treatment. To provide a dental photopolymerizer that will not get in the eyes of the elderly and will not interfere with the restoration work of the teeth, and will not easily break even if the light guide part is dropped on the floor etc. There is.

本発明の歯科用光重合器は、前記した目的を達成せんとするもので、請求項1の手段は、一端が歯科用光重合器本体に対して着脱自在に取付けられ該歯科用光重合器本体からの可視光を先端面に向かって放射し、かつ、先端面に至る途中に屈曲部が形成された導光部と、該導光部の先端部分に着脱自在に装着される全体が筒状に形成されると共に導光部に装着した状態において先端部は導光部の先端面と面一となるように垂直に形成され、後端部は前記導光部の屈曲部における曲率半径の小さい側が短くなるように形成されると共に前記後端部が短く形成された部分の略中間部に開口部が形成され、また、内周面における先端側と後端側には長手方向に沿って複数本のリブが形成された柔軟性を有し、かつ、光不透過性のゴムや合成樹脂で構成した遮光部材とから構成したことを特徴とする。 The dental photopolymerizer according to the present invention achieves the above-described object, and the means of claim 1 has one end detachably attached to the dental photopolymerizer body and the dental photopolymerizer. A light guide unit that emits visible light from the main body toward the tip surface, and a bent portion is formed on the way to the tip surface, and the entirety that is detachably attached to the tip portion of the light guide unit In the state of being formed in a shape and mounted on the light guide, the tip is formed perpendicular to the tip surface of the light guide, and the rear end is the radius of curvature of the bent portion of the light guide. An opening is formed in a substantially middle portion of the portion where the rear end portion is formed short and the small end is shortened, and the front end side and the rear end side of the inner peripheral surface are along the longitudinal direction. It is flexible and has multiple ribs and is made of light-impermeable rubber or synthetic resin. Characterized by being composed of the the light blocking member.

本発明は前記したように、可視光を誘導する導光部の屈曲部における少なくとも外径部を覆う筒状の遮光部材を着脱自在に装着したので、施術中に導光部より光が外部に漏れることがないので、ドクターなどの施術者が歯牙の修復作業を行う際に施術者の視覚に入ることがなく、従って、施術に支障をきたすことがなく安心して施術が行えるものである。   In the present invention, as described above, since the cylindrical light-shielding member that covers at least the outer diameter portion of the bent portion of the light guide for guiding visible light is detachably attached, light is transmitted from the light guide to the outside during the treatment. Since there is no leakage, the practitioner, such as a doctor, does not enter the visual sense of the practitioner when performing the restoration work on the teeth. Therefore, the practitioner can perform the operation without any trouble.

また、遮光部材の略中間部に、屈曲性を良くするための開口部を形成したので、導光部の湾曲に対してフィットした状態で装着でき、かつ、導光部への装着が簡単に行えるものである。   In addition, since an opening for improving flexibility is formed in the substantially middle part of the light shielding member, it can be mounted in a state fitted to the curvature of the light guide unit, and can be easily mounted on the light guide unit. It can be done.

さらに、遮光部材の内面に導光部に対して線接触となるように複数のリブを形成したので、導光部への装着および取外し時における摩擦抵抗が小さくなって着脱が簡単に行え、また、着脱自在が可能であることから、導光部が破損したような場合にも、遮光部材は他の光重合器に利用することが可能である。   In addition, since a plurality of ribs are formed on the inner surface of the light shielding member so as to be in line contact with the light guide portion, the frictional resistance during attachment to and removal from the light guide portion is reduced, and attachment / detachment can be performed easily. Since it is detachable, the light shielding member can be used for other photopolymerization devices even when the light guide is damaged.

また、遮光部材を柔軟性を有するので、メーカによって形状が異なる導光部にも装着することが可能であり、かつ、光不透過性の材料であることから、光漏れによる施術者の目に対する眩しさを与えることがない等の効果を有するものである。   In addition, since the light-shielding member has flexibility, it can be attached to a light guide part having a different shape depending on the manufacturer and is a light-impermeable material. It has effects such as not giving glare.

本発明は、可視光を誘導する導光部の屈曲部における少なくとも外径部を覆う筒状の遮光部材を装着したものである。   The present invention is provided with a cylindrical light shielding member that covers at least the outer diameter portion of the bent portion of the light guide portion that guides visible light.

以下、本発明に係る歯科用光重合器の一実施例を図面とともに説明する。
1は公知の歯科用光重合器本体、2は該歯科用光重合器本体1に対して着脱自在に取付けられ、前記歯科用光重合器本体1から放射される可視光を誘導するための導光部であり、先端面2bに至る途中に屈曲部2aが形成されている。
An embodiment of a dental photopolymerizer according to the present invention will be described below with reference to the drawings.
1 is a known dental photopolymerizer body, 2 is detachably attached to the dental photopolymerizer body 1, and guides the visible light emitted from the dental photopolymerizer body 1. A bent portion 2a is formed on the way to the distal end surface 2b, which is an optical portion.

3は柔軟性を有し、かつ、光不透過性のゴムや合成樹脂で形成した円筒状の遮光部材にして、先端部3aは垂直に、後端部3bは後述する開口部3c側が前記先端部3aよりの長さが短くなるようにカットされている。これは、遮光部材3を前記導光部2に装着する際に、挿入し易くするためである。   3 is a cylindrical light-shielding member made of a light-impermeable rubber or synthetic resin, and the front end portion 3a is vertical, and the rear end portion 3b is on the opening 3c side described later. It is cut so that the length from the portion 3a is shortened. This is to facilitate insertion when the light shielding member 3 is mounted on the light guide 2.

また、遮光部材3の略中間部には開口部3cが形成されている。これは、遮光部材3を導光部2に装着した状態において、導光部2における屈曲部2aの内径部(曲率半径が小さい側)による屈曲率に対応させてフィットさせるためである。この場合、開口部3cと対応する延伸部3dは延びることは当然である。   In addition, an opening 3 c is formed in a substantially middle portion of the light shielding member 3. This is because, in a state where the light shielding member 3 is mounted on the light guide unit 2, the light guide unit 2 is fitted in accordance with the bending rate by the inner diameter portion (the side with the smaller radius of curvature) of the bent portion 2 a. In this case, the extending portion 3d corresponding to the opening 3c naturally extends.

さらに、遮光部材3の内周面における先端側と後端側にそれぞれ複数本のリブ3e,3fが形成されている。これは、遮光部材3を導光部に装着する際、および取り外す際に遮光部材3の内周面と導光部の外周面との接触面積を小さくして着脱を容易にするためである。 Further, a plurality of ribs 3e and 3f are formed on the front end side and the rear end side on the inner peripheral surface of the light shielding member 3, respectively. This light shielding member 3 when mounting the light guide 2, and the contact area between the inner and outer circumferential surfaces of the light guide 2 of the shielding member 3 when removing small to in order to facilitate the detachment is there.

前記した遮光部材3を前記導光部2に装着することで、歯科用光重合器本体1から導光部2に導入された可視光の光が導光部2内で乱反射しても、遮光部材3が光不透過性であることから外部に漏れることがなく、従って、図5に示すように、歯牙の修復部への照射方向Xに対して、乱反射による可視光がドクター等の施術者Aの目に入ることがなく、従来のような眩しさによる施術の不都合を防止できる。   By mounting the light shielding member 3 on the light guide unit 2, even if the visible light introduced from the dental photopolymerizer body 1 to the light guide unit 2 is irregularly reflected in the light guide unit 2, the light shielding unit 3 is shielded. Since the member 3 is light-impermeable, it does not leak to the outside. Therefore, as shown in FIG. 5, the visible light due to irregular reflection is applied to the restoration direction of the tooth by a practitioner such as a doctor. The inconvenience of the treatment due to glare as in the past can be prevented without entering the eyes of A.

また、遮光部材3は、ゴムや合成樹脂等の柔軟性を有する材料で構成されているので、万一床などに落下させても落下の衝撃が緩和され導光部2の破損を防止することができ、さらに、遮光部材3の先端部3aを導光部2の先端面2aと面一となるように装着することで、前記衝撃において導光部2の先端面2bも保護されるものである。 Further, since the light shielding member 3 is made of a flexible material such as rubber or synthetic resin, even if it is dropped on the floor or the like, the impact of the fall is alleviated and the light guide 2 is prevented from being damaged. Furthermore, by mounting the tip 3a of the light shielding member 3 so as to be flush with the tip 2a of the light guide 2, the tip 2b of the light guide 2 is protected in the impact. is there.
