図１は、本発明による口腔内照明器具の一実施例を説明するための要部構成図で、図１（Ａ）は軸方向断面図、図１（Ｂ）は光照射部（Ｂ−Ｂ線）断面図、図１（Ｃ）はバイトブロック部（Ｃ−Ｃ線）断面図を示し、本発明による口腔内照明器具１０は、軸方向に延長する光照射部１１と該光照射部１１の軸方向に一体的に連続するバイトブロック部１２とから成り、該バイトブロック部１２は軸中心に軸方向に延長する凹部１２ａを有し、該凹部１２ａに光源を挿脱自在に挿入できるようになっており、光照射部１１を口腔の奥部に入れ、バイトブロック部１２を噛むことによって固定するようになっている。バイトブロック部１２は、口を開けた状態をそのまま維持できる程度の高さ（又は径）に形成されており、歯科治療中、患者が口を開けているのを支える支持部材として機能し、これによって、患者は、歯科治療中、楽に口を開けていることができる。そのため、口腔内照明器具１０は、患者の口の大きさに応じて、大、中、小等何種類か準備しておき、患者の口の大きさに合ったものを適宜選択して使用するようになっている。   FIG. 1 is a main part configuration diagram for explaining an embodiment of an intraoral lighting device according to the present invention, FIG. 1 (A) is an axial sectional view, and FIG. 1 (B) is a light irradiation part (BB). 1C is a cross-sectional view of the bite block portion (CC line). An intraoral lighting device 10 according to the present invention includes a light irradiation unit 11 extending in the axial direction and the light irradiation unit 11. The bite block portion 12 has a concave portion 12a extending in the axial direction at the center of the shaft so that a light source can be removably inserted into the concave portion 12a. The light irradiation part 11 is put in the back part of the oral cavity, and the bite block part 12 is bitten and fixed. The bite block 12 is formed to have a height (or diameter) that can maintain the open state as it is, and functions as a support member that supports the patient's open mouth during dental treatment. Allows the patient to open his mouth easily during dental treatment. Therefore, the intraoral lighting apparatus 10 is prepared according to the size of the patient's mouth, and several types such as large, medium, and small are prepared, and the one that matches the size of the patient's mouth is appropriately selected and used. It is like that.

光照射部１１の形状は、図１（Ｂ1）に示すように断面が円形の柱状体、或いは、図１（Ｂ2）に示すように断面が中央部が肉厚の扁平体、或いは、図１（Ｂ3）に示すように、中央部１１1を円形又は肉厚部とする板状体、図１（Ｂ4）に示すように中央部１１1を円形又は肉厚部とするＸ形状板等、バイトブロック部１２から導入された光を放射することができるものなら何でもよい（なお、図１（Ｂ1）〜（Ｂ4）において点線にて示す１１ａは、後述するように、この部分に導光用の孔が設けられていてもよいことを示すものである）。しかし、好ましくは、バイトブロック部１２と一体成形でき、オートクレーブが可能で、しかも、バイトブロック部１２を噛みながら治療を受けるものであるため、噛み続けても疲労しにくいゴム系で弾力性がある、例えば、シリコーンゴム材などがよい（樹脂などの硬いものだと、顎が疲れる）。また、光を効果的に伝達、分散させるためには、半透明体の材料がよい。 The shape of the light irradiation part 11 is a columnar body having a circular cross section as shown in FIG. 1 (B 1 ), a flat body having a thick central part as shown in FIG. 1 (B 2 ), or As shown in FIG. 1 (B 3 ), a plate-like body having the central portion 11 1 as a circular shape or a thick portion, and as shown in FIG. 1 (B 4 ), the central portion 11 1 as a circular shape or a thick portion. Any material can be used as long as it can emit light introduced from the bite block unit 12 such as a shape plate (in addition, 11a indicated by a dotted line in FIGS. 1 (B 1 ) to (B 4 ), This indicates that a light guide hole may be provided in this portion). However, since it can be molded integrally with the bite block portion 12 and can be autoclaved, and is subjected to treatment while biting the bite block portion 12, it is elastic with a rubber system that does not get tired even if it continues to bite. For example, a silicone rubber material is good (if it is hard such as resin, the jaws get tired). In order to effectively transmit and disperse light, a semi-transparent material is preferable.

バイトブロック部１２は、光源を挿脱自在に連結するための凹部１２ａを有するが、この凹部１２ａは、口腔内光照射器具１０の大、小にかかわらず、同じ大きさに形成されており、全ての光照射器具１０に対して、単一の光源を共通使用可能としている。   The bite block 12 has a recess 12a for detachably connecting the light source, but the recess 12a is formed in the same size regardless of whether the intraoral light irradiation device 10 is large or small. A single light source can be used in common for all the light irradiation instruments 10.

バイトブロック部１２は、口腔内に挿入した時に、口を開いた状態を維持するのに適した高さ（太さ）Ｈを有すればよく、図１（Ｃ1）には、バイトブロック部１２を円形にした例を示したが、上下面を平面に形成してもよく、更には、図１（Ｃ2）に示すように、上下に歯列に沿う溝１２Ｕ，１２Ｌを設け、この溝１２Ｕ，１２Ｌを上歯及び下歯に沿わせ、該溝の上下で噛むようにすると、バイトブロック部１２をより効果的に安定して噛むことができ、光照射器具１０をより確実に固定することができる。 The bite block portion 12 only needs to have a height (thickness) H suitable for maintaining an open state when inserted into the oral cavity. FIG. 1 (C 1 ) shows the bite block portion. Although the example in which 12 is made circular is shown, the upper and lower surfaces may be formed in a plane, and further, as shown in FIG. 1 (C 2 ), grooves 12U and 12L along the tooth row are provided on the upper and lower sides. If the grooves 12U and 12L are arranged along the upper and lower teeth and are bited above and below the grooves, the bite block 12 can be bited more effectively and stably, and the light irradiation device 10 can be more securely fixed. can do.

光源部２０は、図１に破線にて示したように、先端部に光源（例えば、ＬＥＤ、ハロゲンランプ等、より太陽光に近い色温度を発生するものを用いる）２１を有し、光源部２０をバイトブロック部１２の凹部１２ａに挿し込み、図示しないコントローラにより、該光源２１を点灯すると、該光源２１からの光は、光照射器具１０を構成している例えばシリコーンゴムを通して光照射部１１に伝達され、該光照射部１１より照射されて口腔内を照明する。   The light source unit 20 includes a light source (for example, an LED, a halogen lamp, or the like that generates a color temperature closer to sunlight) 21 at the tip, as indicated by a broken line in FIG. When 20 is inserted into the recess 12a of the bite block 12 and the light source 21 is turned on by a controller (not shown), the light from the light source 21 passes through, for example, the silicone rubber constituting the light irradiating device 10. And is irradiated from the light irradiation unit 11 to illuminate the oral cavity.

図２は、本発明による口腔内照明器具の他の実施例を説明するための軸方向断面構成図で、この実施例は、光照射部１１にバイトブロック部１２の凹部１２ａに連通する軸方向の孔（導光路）１１ａを設けたもので（図１に示した実施例においても、点線（仮想線）１１ａにて示すように設けてもよい）、このようにすると、導光路１１ａを通して凹部１２ａに挿入された光源からの光をより効果的に光照射部１１の先端部まで導くことができ、該光照射部１１からより均一に光を照射することができる。なお、図２には、光照射部１１の形状を中心部を円形又は肉厚にした断面Ｘ型の光照射部１１（図１（Ｂ4）に相当）を示したが、上下面を平面に形成してもよく、更には、このようにすると、中心部の太い部分（円形又は肉厚の部分）１１1又は該太い部分に形成した導光路１１ａに光が通り、そこから枝分かれした上下、前後の各部分１１Ｕ1，１１Ｕ2，１１Ｌ1，１１Ｌ2に光が走り、口腔内をよりくまなく照明することができる。 FIG. 2 is an axial sectional configuration diagram for explaining another embodiment of the intraoral lighting device according to the present invention. This embodiment is an axial direction in which the light irradiation section 11 communicates with the recess 12 a of the bite block section 12. 1a (in the embodiment shown in FIG. 1, it may be provided as indicated by a dotted line (virtual line) 11a), and in this way, a recess is formed through the light guide 11a. The light from the light source inserted into 12a can be more effectively guided to the tip of the light irradiation unit 11, and the light irradiation unit 11 can irradiate light more uniformly. FIG. 2 shows the light irradiation unit 11 having an X-shaped section (corresponding to FIG. 1 (B 4 )) in which the center of the light irradiation unit 11 is circular or thick. may be formed, and further, with this structure, a street light in a thick portion light guide path 11a formed in the (circular or part of the thickness) 11 1 or the thick have parts of the heart, the upper and lower, which branches therefrom The front and rear portions 11U 1 , 11U 2 , 11L 1 , 11L 2 run light, and the oral cavity can be illuminated all over.

更には、光照射部１１は、該光照射部１１を口腔の奥側において舌の上を横切って這わせる長さＬを有し、かつ、舌の動きを抑制する幅Ｗを有し、従来、臼歯の治療の際、舌が邪魔で該舌の動きに注意を払いながら治療していたが、本発明によると、上述のようにして、光照射部１１によって舌の動きを抑制することができ、より安全に治療することができる。   Furthermore, the light irradiation unit 11 has a length L that allows the light irradiation unit 11 to crawl across the tongue on the back side of the oral cavity, and has a width W that suppresses the movement of the tongue. In the treatment of molars, the tongue is disturbing and the treatment is performed while paying attention to the movement of the tongue. However, according to the present invention, the light irradiation unit 11 can suppress the movement of the tongue as described above. Can be treated more safely.

図３は、本発明による口腔内照明装置の一実施例を説明するための要部概略構成図で、図中、１０は本発明による口腔内照明器具１０の一例としての図２に示した口腔内照明器具の斜視図、２０は該口腔内照明器具１０のバイトブロック部１２の凹部１２ａ内に挿脱自在に挿入される光源２１を先端部に有する光源部２０の斜視図で、本発明による口腔内照明装置は、前述のごとき、口腔内照明器具１０と光源部２０とから成り、口腔内照明器具１０を、前述のようにして、患者の口腔内に入れ、光源部２０を凹部１２ａ内に挿入し、光源２１を点灯すれば、該光源２１からの光が光照射部１１に伝達され、該光照射部１１より照射されて口腔内が照明される。   FIG. 3 is a schematic configuration diagram of a main part for explaining an embodiment of the intraoral lighting device according to the present invention. In FIG. 3, reference numeral 10 denotes the oral cavity shown in FIG. 2 as an example of the intraoral lighting device 10 according to the present invention. FIG. 20 is a perspective view of the inner illuminating device, and FIG. 20 is a perspective view of the light source unit 20 having a light source 21 detachably inserted into the recess 12a of the bite block 12 of the intraoral lighting device 10 at the tip, according to the present invention. The intraoral lighting device includes the intraoral lighting device 10 and the light source unit 20 as described above. The intraoral lighting device 10 is placed in the patient's oral cavity as described above, and the light source unit 20 is placed in the recess 12a. When the light source 21 is turned on, the light from the light source 21 is transmitted to the light irradiation unit 11 and irradiated from the light irradiation unit 11 to illuminate the oral cavity.

図４は、本発明による口腔内照明装置を使用して患者の口腔内を照明している時の様子を示す図で、図４（Ａ）は、患者がバイトブロック部１２を噛んでいる時の様子を側面から見た図、図４（Ｂ）は、患者の口腔内奥方において、光照射部１１が患者の舌Ｔの上を横切って延長し、舌Ｔを上側から抑え、該舌Ｔの動きを抑えている様子を示す図である。このように、本発明による口腔内照明器具を使用することにより、舌Ｔの動きを抑制することができ、より安全に治療することができる。   FIG. 4 is a view showing a state in which the intraoral illumination device according to the present invention is used to illuminate the patient's oral cavity, and FIG. 4 (A) shows a state where the patient is biting the bite block portion 12. FIG. 4 (B) shows a side view of the state of FIG. 4B. In the back of the patient's oral cavity, the light irradiation unit 11 extends across the patient's tongue T, restrains the tongue T from above, and the tongue T It is a figure which shows a mode that the movement of is suppressed. Thus, by using the intraoral lighting device according to the present invention, the movement of the tongue T can be suppressed, and treatment can be performed more safely.

図５は、本発明による口腔内照明装置の全体構成の一例を示す概略斜視図で、図中、１０は、口腔内照明器具（１１は光照射部、１２はバイトブロック部）、２０は光源部（先端に光源（図示せず）を有する）、３０は光源用のリード線、４０は光源の明るさを調整するコントローラで、該コントローラ４０は光量調整用のボリウム４１を有し、該ボリウム４１によって電源のオン・オフを制御し、かつ、光量を調整し、口腔内の明るさを調整する。なお、図には、光源部２０をバイトブロック部１２に対して挿脱自在とし、コントローラ４０によって光量を調整するようにした例を示したが、光源部に光源と電池を一体的に組み込んでおき、この光源と電池を一体的にした光源部をバイトブロック部に挿脱自在に組み込んでおき、患者がバイトブロック部１２を噛んだ時にスイッチがオンして光源が点灯するようにする等してもよい。   FIG. 5 is a schematic perspective view showing an example of the overall configuration of the intraoral lighting device according to the present invention, in which 10 is an intraoral lighting device (11 is a light irradiation unit, 12 is a bite block unit), and 20 is a light source. (Having a light source (not shown) at the tip), 30 is a lead wire for the light source, 40 is a controller for adjusting the brightness of the light source, and the controller 40 has a volume 41 for adjusting the light amount. The power on / off is controlled by 41, the light quantity is adjusted, and the brightness in the oral cavity is adjusted. Although the figure shows an example in which the light source unit 20 is detachable with respect to the bite block unit 12 and the amount of light is adjusted by the controller 40, the light source and the battery are integrated into the light source unit. In addition, a light source unit in which the light source and the battery are integrated is removably incorporated in the bite block unit so that when the patient bites the bite block unit 12, the switch is turned on and the light source is turned on. May be.

これまでの口腔内照明は、無影灯のような口腔外照明装置を用いるもの、歯科治療用インスツルメントの先端から光を照射するもの等しかなく、術者の視線方向の一部にしか光を当てることが出来なかったが、本発明によると、口腔内から照明できるため、口腔内全体を明るく出来、これにより、目線を口腔内のどこに向けても常時明るい状態で観察できる。また、光源部は光照射部と分離可能になっており、口腔内に挿入される光照射部を容易にオートクレーブ等することができる。   Conventional intraoral illumination includes only those that use an extraoral illumination device such as a surgical light and those that irradiate light from the tip of an instrument for dental treatment, and only in a part of the line of sight of the operator. Although the light could not be applied, according to the present invention, since it can be illuminated from the oral cavity, the entire oral cavity can be brightened, so that the eye can be always observed in a bright state regardless of where the eye is directed in the oral cavity. Moreover, the light source part is separable from the light irradiation part, and the light irradiation part inserted into the oral cavity can be easily autoclaved.

更には、光源の照度を光源用ボリウムにより調整が出来るようにすることにより、使用者の好みに合った照度が得られ、目の疲れが軽減される。光源はＬＥＤやハロゲンランプを使用することにより、より太陽光に近い色温度を提供することができる。更には、光照射部を口腔内の奥側で舌の上を横断するように這わせて延長させ、これによって、従来は臼歯の治療の際舌が邪魔で動きに注意を払いながら治療していたが、光照射部により舌の動きを抑制することができ、これまでより安全に治療できる。
バイトブロック部を患者が噛みつつ治療を受けるため、ゴム系で弾力性がありオートクレーブ可能な材料（シリコーンなど）を使用し、噛み続けても疲労しにくくなっている（樹脂など硬いものだと顎が疲れる）。
バイトブロック部は光源からの熱により若干暖かくなり、知覚過敏の患者への負担軽減を行うことができる。 Furthermore, by making it possible to adjust the illuminance of the light source with the volume for the light source, the illuminance suitable for the user's preference can be obtained, and eye fatigue can be reduced. The light source can provide a color temperature closer to that of sunlight by using an LED or a halogen lamp. In addition, the light irradiation part is extended so that it crosses over the tongue at the back side in the oral cavity, so that in the conventional treatment of the molars, the tongue is obstructed and the treatment is performed while paying attention to the movement. However, the movement of the tongue can be suppressed by the light irradiation unit, and treatment can be performed more safely than before.
Because the bite block is treated while the patient is biting, it uses a rubber-based, elastic and autoclavable material (silicone, etc.), which makes it difficult to get tired even if it continues to bite (if it is hard such as resin, the jaw Tired).
The bite block is slightly warmed by the heat from the light source, and can reduce the burden on hypersensitive patients.
