Description
【０００１】[0001]
本考案は、光重合用光照射器、より詳細には、歯科治療において、例えば、歯 牙形成後の修復材として使用する光硬化性レジンを硬化させるための光照射器に 関する。 The present invention relates to a light irradiator for photopolymerization, and more particularly to a light irradiator for curing a photocurable resin used in dental treatment, for example, as a restorative material after tooth formation.
【０００２】[0002]
歯科治療においては、歯牙形成後の修復材として光重合レジンを用いるが、こ の光重合レジンは、例えば、歯牙の修復材として使用する場合、歯牙の破損箇所 へ接着した後、光を照射して硬化させ、硬化後、切削、研磨等を行って、元の歯 牙と一体化させて破損前の歯牙を審美性を持たせて修復するものである。 In dental treatment, a photo-polymerized resin is used as a restorative material after tooth formation.For example, when used as a tooth restorative material, this photo-polymerized resin is irradiated with light after adhering to a damaged part of the tooth. It hardens, and after hardening, it is integrated with the original tooth by cutting, polishing, etc., and the tooth before damage is restored with aesthetics.
【０００３】 図２は、上述のごとき歯牙の修復の仕方を説明するための図で、図中、１０は 破損箇所Ａを有する歯牙（元の歯牙）で、この破損箇所を修復するために、この 破損箇所に光重合レジンを接着する。この時、レジンは破損箇所Ａを含むように 大めに（Ｂの領域まで）接着する。このようにして、破損した歯牙の破損部にレ ジンを接着した後、光照射器２０によりレジンを硬化させ、その後、Ｂ部を切削 、研磨等を行って取り除き、Ａ部のレジンのみを残し、これによって、Ａ部を含 む元の歯牙に修復するものである。FIG. 2 is a diagram for explaining a method of repairing a tooth as described above. In the figure, reference numeral 10 denotes a tooth having a damaged portion A (original tooth). The photopolymerizable resin is adhered to this damaged part. At this time, the resin is adhered largely (up to the area B) so as to include the damaged portion A. In this way, after bonding the resin to the damaged part of the damaged tooth, the resin is cured by the light irradiator 20, and then part B is cut and polished to remove it, leaving only the part A resin. By this, the original tooth including the part A is restored.
【０００４】 図３は、従来の光照射器の一例を説明するための概略構成図で、図中、２１は 光源、２２は楕円反射ミラー、２３はフィルター、２４はライトガイド（光導体 ）、２５はリード線で、周知のように、光源２１は楕円反射ミラー２２の焦点位 置にあり、該光源２１からの光を楕円反射ミラー２２で反射する。この反射光は 、前記楕円反射ミラーの焦点と対をなす他方の焦点位置近傍にその受光端が配設 されたライトガイド２４内に導入され、該ライトガイド２４を通して伝送されて 、前述のようにして光重合レジンに照射される。なお、フィルタ２３は、光源２ １からの光のうち、光重合に必要な光波長成分の光のみを透過させるもので、例 えば、４７８ｎｍの波長成分の光のみを通過させる。FIG. 3 is a schematic configuration diagram for explaining an example of a conventional light irradiator. In the figure, 21 is a light source, 22 is an elliptical reflection mirror, 23 is a filter, 24 is a light guide (optical conductor), Reference numeral 25 denotes a lead wire, and as is well known, the light source 21 is located at the focal position of the elliptical reflection mirror 22, and the light from the light source 21 is reflected by the elliptical reflection mirror 22. This reflected light is introduced into a light guide 24 whose light receiving end is arranged in the vicinity of the other focal position of the elliptical reflecting mirror, and is transmitted through the light guide 24. The photopolymerized resin is irradiated. It should be noted that the filter 23 transmits only the light of the light wavelength component necessary for photopolymerization among the light from the light source 21 and, for example, passes only the light of the wavelength component of 478 nm.
【０００５】[0005]
而して、上記従来の光照射器においては、楕円反射ミラー２２の径が大きく、 そのため、光照射器２０全体の径が大きくなり、持ちにくく、取り扱いにくいと いった欠点があった。勿論、楕円反射ミラーの径を小さくすれば、全体の径を小 さくすることができるが、そうすれば、光量不足をきたし、レジンを迅速に硬化 できないという問題を生じる。 Therefore, in the above-mentioned conventional light irradiator, the diameter of the elliptical reflection mirror 22 is large, and therefore, the diameter of the entire light irradiator 20 is large, which makes it difficult to hold and difficult to handle. Of course, if the diameter of the elliptical reflection mirror is made small, the whole diameter can be made small. However, if this is done, there is a problem that the amount of light becomes insufficient and the resin cannot be cured quickly.
【０００６】[0006]
本考案は、上記課題を解決するために、楕円反射ミラーと、該楕円反射ミラー の焦点位置に配設された光源と、該楕円反射ミラーの焦点と対をなす他方の焦点 近傍に配設され、前記楕円反射ミラーからの反射光が導入される光導体とから成 り、該光導体から照射される光によって光重合を行う光重合用光照射器において 、前記２つの焦点間に前記楕円反射ミラーに続く楕円面上に第２の反射ミラーを 別に有することを特徴としたものである。 In order to solve the above problems, the present invention provides an elliptical reflection mirror, a light source arranged at the focal position of the elliptical reflection mirror, and a light source arranged near the other focal point of the elliptical reflection mirror. A light guide for introducing light reflected from the elliptical reflection mirror, wherein the light emitted from the light guide is used for photopolymerization, wherein the elliptical reflection is between the two focal points. It is characterized in that a second reflecting mirror is additionally provided on the elliptical surface following the mirror.
【０００７】[0007]
楕円反射ミラーの焦点位置に光源を配設するとともに該楕円反射ミラーの前に 、楕円面の一部を形成する第２の反射ミラーを設け、該第２の反射ミラーからの 反射光をも反射させ、該楕円反射ミラーの他方の焦点位置に受光端が配設された 光導体内に導入するようにし、光源からの光を効率よく光導体内に導入するよう にする。 A light source is arranged at the focal point of the elliptical reflection mirror, and a second reflection mirror forming a part of the elliptical surface is provided in front of the elliptical reflection mirror to reflect the reflected light from the second reflection mirror. Then, the light from the light source is efficiently introduced into the optical body in which the light receiving end is arranged at the other focal position of the elliptical reflecting mirror.
【０００８】[0008]
図１は、本考案による光照射器の一実施例を説明するための要部概略構成図で 、図中、図３に示した従来技術と同様の作用をする部分には、図３の場合と同一 の参照番号を付してある。而して、本考案においても前述のように、光源２１は 楕円反射ミラー２２の略焦点位置に取り付けられており（反射ミラーと一体的で も、或いは、別体でもよい）、ライトガイド２４の受光端は楕円面の他の略焦点 位置に設けられている。従って、光源２１から放射された光は、前記従来技術と 同様、楕円反射ミラー２２によって反射されてライトガイド２４内に導入される 。而して、本考案においては、楕円反射ミラー２２とライトガイド２４の受光端 との間の楕円面の一部に第２の反射ミラー２６を別に設け、該第２の反射ミラー ２６によっても光源２１からの光を反射させ、この第２の反射ミラー２６からの 光をもライトガイド２４内に導入するようにしている。 FIG. 1 is a schematic configuration diagram of an essential part for explaining an embodiment of a light irradiator according to the present invention. In the figure, a portion having the same operation as that of the prior art shown in FIG. The same reference number is attached. Thus, in the present invention, as described above, the light source 21 is attached to the elliptical reflection mirror 22 at a substantially focal position (which may be integrated with the reflection mirror or may be a separate body), and the light guide 24 of the light guide 24. The light-receiving end is provided at another approximate focus position on the ellipsoid. Therefore, the light emitted from the light source 21 is reflected by the elliptical reflection mirror 22 and introduced into the light guide 24, as in the prior art. Thus, in the present invention, a second reflecting mirror 26 is separately provided on a part of the elliptical surface between the elliptical reflecting mirror 22 and the light receiving end of the light guide 24, and the second reflecting mirror 26 also serves as a light source. The light from the second reflecting mirror 26 is reflected, and the light from the second reflecting mirror 26 is also introduced into the light guide 24.
【０００９】 上述のように、本考案においては、従来の楕円反射ミラーに加えて、第２の反 射ミラーを設け、光源からの光をこの第２の反射ミラーによっても反射してライ トガイドに導入するようにしたので、光源からの光を効率よくライトガイド内に 導入することができ、従って、楕円反射ミラーの径（楕円の短径）を短くするこ とができ、これによって、光照射器全体の径Ｐを小径にすることが可能となる。As described above, in the present invention, the second reflection mirror is provided in addition to the conventional elliptical reflection mirror, and the light from the light source is also reflected by the second reflection mirror to be used as the light guide. Since the light is introduced, the light from the light source can be efficiently introduced into the light guide, and therefore the diameter of the elliptical reflection mirror (the minor axis of the ellipse) can be shortened. It is possible to reduce the diameter P of the entire container.
