近時、歯科の診療においても、歯科用診療台の近傍に顕微鏡装置を配置して、診療精度をより高めるようにした歯科用診療装置が多く採用されるようになった（特許文献１〜３参照）。特許文献１〜３には、歯科用診療台の側部に設けられるアームや支柱に支持されるハンガーアームと、該ハンガーアームの先端に取付けられる顕微鏡本体とから構成される顕微鏡装置が開示されている。

ところで、特許文献１〜３に開示されたような顕微鏡装置を備えた歯科用診療装置の場合、歯科用診療台の側部に直接或いはスピットン装置を介して一体に設けられたアームや支柱に支持されている。そのため、診療台を昇降させ、或いは、無影灯（デンタルライト）やインスツルメント類を操作すると、アームや支柱を介して顕微鏡本体に振動が伝達し、その間は、顕微鏡による正確な患部の観察診療を行うことができなくなる。顕微鏡は、細部の対象を拡大して観察するものであるから、わずかな振動でも観察視野に大きな影響を及ぼす。特に、前記支柱は診療台に一体とされたスピットン装置に設けられ、該支柱が無影灯の支柱を兼ねていたり、スピットン装置にアシスタント用のインスツルメントホルダが設けられていたりすると、アシスタントの無影灯やインスツルメントの操作によって、顕微鏡本体が不意に振動し、術者はこれによってフラストレーションが溜まって正常な診療を行えなくなる事態も生じる。このような振動は、顕微鏡本体を位置付け操作する際にも生じ、しかも、一旦振動が発生すると、直ぐには治まらず、これによって診療効率が阻害されることもある。 By the way, in the case of a dental medical device equipped with a microscope device as disclosed in Patent Documents 1 to 3, it is supported by an arm or a support column provided directly on the side of the dental medical table or through a spitton device. Has been. Therefore, when the clinic is moved up and down, or when operating a surgical light (dental light) or instruments, vibration is transmitted to the microscope body via the arm or column, and during that time, accurate observation of the affected area is performed with the microscope. Cannot perform medical treatment. Since the microscope observes a detailed object in an enlarged manner, even a slight vibration greatly affects the observation field. In particular, the support column is provided in a spitton device integrated with a medical desk, and the support column also serves as a surgical light support column or an instrument holder for an assistant is provided in the spit device. The operation of the surgical light or the instrument may cause the microscope body to vibrate unexpectedly, causing the surgeon to accumulate frustration and failing to perform normal medical care. Such vibration also occurs when the microscope body is positioned and operated. Moreover, once the vibration is generated, it does not heal immediately, and this may impede medical efficiency.

前記のような顕微鏡本体の振動は、診療台に設けられている場合に限られず、診療室の天井に設けられている場合、壁面に設けられている場合、或いは、床面を移動自在に配備される移動備品に設けられている場合であっても、人の動きや各種機器（例えば、エアコン等）の作動等の周囲環境によって発生することもある。特許文献１〜３には、このような振動を防止する機構について、特に言及されていない。特許文献４には、天吊式手術用顕微鏡の除震架台が開示されているが、天井裏に大掛かりな装置を組込む必要があり、実用化の面で難点があった。さらに、特許文献５に開示された防振顕微鏡は、顕微鏡光学系の傾斜を測定するセンサ、顕微鏡光学系の移動を検出するセンサ、顕微鏡光学系内を進行する被写体光を所望の方向へ所望の角度で偏向する偏向手段等によって構成される。この場合、防振構成が複雑であり、また、マイクロモータを用いてフィードバック情報を管理する必要もあるため、コストが高くなることは避けられなかった。 The vibration of the microscope body as described above is not limited to the case where the microscope body is provided on the examination table, but the case where the microscope body is provided on the ceiling of the examination room, the case where it is provided on the wall surface, or the floor surface is movably arranged. Even if it is provided in the mobile equipment, it may occur due to the surrounding environment such as the movement of a person and the operation of various devices (for example, an air conditioner). Patent Documents 1 to 3 do not particularly mention a mechanism for preventing such vibration. Patent Document 4 discloses a vibration isolation frame for a ceiling-mounted surgical microscope. However, it is necessary to incorporate a large-scale device behind the ceiling, which is difficult to put into practical use. Furthermore, the vibration-proof microscope disclosed in Patent Document 5 includes a sensor for measuring the tilt of the microscope optical system, a sensor for detecting movement of the microscope optical system, and subject light traveling in the microscope optical system in a desired direction. It is comprised by the deflection | deviation means etc. which deflect by an angle. In this case, the vibration-proof configuration is complicated, and it is necessary to manage feedback information using a micromotor. Therefore, the cost is inevitable.

The brake member may further include a stopper function unit that is mounted across the connection member and the fixed support shaft. In addition, an elastic buffer member may be attached to a mounting portion of the stopper member with respect to the connection member. Moreover, the said brake member may be provided with the adjustment means which adjusts the press-contact degree with respect to the surrounding surface of the said fixed spindle.

本発明の医療用顕微鏡装置において、前記転がり軸受が、深溝ラジアル玉軸受であっても良い。また、前記固定支軸が、前記医療用診療台に立設される垂直支柱、該医療用診療台が設置される診療室の天井から垂下される垂直支柱、該診療室の床面上に移動自在に配備される移動備品に設けられる垂直支柱、及び、該診療室の壁面に取付けられる取付部材のいずれかに設けられていても良い。 In the medical microscope apparatus of the present invention, the rolling bearing may be a deep groove radial ball bearing.

第２の発明に係る医療用診療装置は、医療用診療台を含む医療用診療装置であって、前記医療用診療台の近傍に、前記いずれかの医療用顕微鏡装置が配置されていることを特徴とする。
本発明の医療用診療装置において、前記固定支軸が、前記医療用診療台の側部に一体に固定された垂直支柱に設けられているものとしても良い。 A medical medical device according to a second invention is a medical medical device including a medical medical table, wherein any one of the medical microscope devices is arranged in the vicinity of the medical medical table. Features.
In the medical treatment apparatus according to the present invention, the fixed support shaft may be provided on a vertical support fixed integrally to a side portion of the medical treatment table.

第１の発明に係る医療用顕微鏡装置及び第２の発明に係る医療用診療装置によれば、術者は、ハンガーアームを水平旋回させて該ハンガーアームに支持された顕微鏡本体を適正位置に位置付け、医療用診療台の上の患者の患部を、顕微鏡本体をとおして観察することができる。この時、前記固定支軸には前述のような周囲環境による様々な振動が伝達されるが、該固定支軸と前記接続部材とは転がり軸受を介して同心的な嵌装接続状態とされているから、転がり軸受を構成する転動体の軌道面間での相互の転動作用により、前記振動がハンガーアームを通じて顕微鏡本体に伝達することが緩和される。従って、術者は振動によって煩わされることなく、患部の顕微鏡観察診療を精度よく実施することができる。また、前記接続部材は、回り止め部材によって、固定支軸に対する相対軸心回転が阻止されるよう構成されているから、前記転がり軸受による作用とも相俟って、前記振動の伝達の防止がより的確になされる。加えて、術者自らが顕微鏡本体を位置決め操作した後の顕微鏡本体及びハンガーアームの惰性的動きも、回り止め部材によって速やかに静止され、顕微鏡観察を含む診療作業全体の効率化が図られる。 According to the medical microscope apparatus according to the first invention and the medical diagnostic apparatus according to the second invention, the operator horizontally rotates the hanger arm and positions the microscope main body supported by the hanger arm at an appropriate position. The affected part of the patient on the medical examination table can be observed through the microscope body. At this time, various vibrations due to the surrounding environment as described above are transmitted to the fixed support shaft, but the fixed support shaft and the connection member are concentrically fitted and connected via a rolling bearing. Therefore, the transmission of the vibration to the microscope body through the hanger arm is mitigated by the mutual rolling operation between the raceway surfaces of the rolling elements constituting the rolling bearing. Therefore, the surgeon can accurately perform the microscopic observation medical treatment of the affected part without being bothered by vibration. In addition, since the connection member is configured to be prevented from rotating relative to the fixed support shaft by the anti-rotation member, the transmission of the vibration is further prevented in combination with the action of the rolling bearing. It is made accurately. In addition, the inertial movement of the microscope main body and the hanger arm after the surgeon himself positions the microscope main body is quickly stopped by the anti-rotation member, thereby improving the efficiency of the entire medical work including the microscope observation.

前記回り止め部材が、前記接続部材と固定支軸とに跨って装着されるストッパ部材を含むので、接続部材の固定支軸に対する相互回転及び前記惰性的動きが確実に阻止され、前記転がり軸受による振動伝達防止機能がより的確に発揮される。この場合、ストッパ部材の前記接続部材に対する装着部に、弾性緩衝部材が取付けられているものとすれば、固定支軸とストッパ部材との相互の当止関係によって、固定支軸の前記振動がストッパ部材に伝達しても、弾性緩衝部材によってこの伝達が吸収され、接続部材及びハンガーアームを介して顕微鏡本体に伝達されることがない。 Since the anti-rotation member includes a stopper member mounted across the connection member and the fixed support shaft, mutual rotation of the connection member with respect to the fixed support shaft and the inertial movement are reliably prevented, and the rolling bearing is used. Vibration transmission prevention function is more accurately demonstrated. In this case, if the elastic buffer member is attached to the mounting portion of the stopper member with respect to the connecting member, the vibration of the fixed support shaft is caused by the mutual contact relationship between the fixed support shaft and the stopper member. Even if it is transmitted to the member, this transmission is absorbed by the elastic buffer member and is not transmitted to the microscope main body via the connecting member and the hanger arm.

また、前記回り止め部材が、前記接続部材に装着され、前記固定支軸の周面に圧接されるブレーキ部材からなる場合、ストッパ部材と同様に、接続部材の固定支軸に対する相互回転及び前記惰性的動きが確実に阻止され、前記転がり軸受による振動伝達防止機能がより的確に発揮される。この場合、ブレーキ作用によって、急激な回り止めがなされず、ハンガーアームを水平旋回させるような操作の際の馴染み性が良くなる。そして、ストッパ部材とブレーキ部材とを併用して、これを回り止め部材とすれば、両者の相乗効果が得られる。或いは、ブレーキ部材が、ストッパ機能部を更に備えているものとすれば、同様の相乗効果が得られる。 Further, when the anti-rotation member is a brake member that is attached to the connection member and pressed against the peripheral surface of the fixed support shaft, the rotation of the connection member with respect to the fixed support shaft and the inertia are similar to the stopper member. Therefore, the function of preventing vibration transmission by the rolling bearing is more accurately exhibited. In this case, due to the braking action, a sudden rotation is not prevented, and the familiarity at the time of the operation of turning the hanger arm horizontally is improved. And if a stopper member and a brake member are used together and this is used as a non-rotating member, the synergistic effect of both will be acquired. Alternatively, if the brake member further includes a stopper function portion, the same synergistic effect can be obtained.

前記転がり軸受を、深溝ラジアル玉軸受とした場合、円柱形の固定支軸の周面（ラジアル面）と、接続部材の円筒形内周面（ラジアル面）との間に当該軸受が介在され、前記軌道面間の転動体の転動作用によって前記振動伝達防止機能がより効果的に発揮される。しかも、深溝であることから、転動体が安定的に保持され、固定支軸と接続部材との鉛直方向での嵌装関係が安定化し、これが振動防止性をより向上させる。 When the rolling bearing is a deep groove radial ball bearing, the bearing is interposed between the peripheral surface (radial surface) of the cylindrical fixed support shaft and the cylindrical inner peripheral surface (radial surface) of the connecting member, The vibration transmission preventing function is more effectively exhibited by the rolling motion of the rolling elements between the raceway surfaces. And since it is a deep groove, a rolling element is stably hold | maintained, the fitting relationship in the vertical direction of a fixed spindle and a connection member is stabilized, and this improves vibration prevention property more.

また、前記固定支軸は、前記医療用診療台に立設される垂直支柱、該医療用診療台が設置される診療室の天井から垂下される垂直支柱、該診療室の床面上に移動自在に配備される移動備品に設けられる垂直支柱、及び、該診療室の壁面に取付けられる取付部材のいずれかに設けることができる。従って、医療用診療装台及びこれが設置される診療室の仕様に応じて、当該顕微鏡装置の配置レイアウトを設定することができ、いずれの場合でも、前記防振機能が発揮され、精度良く、術者がフラストレーションを持つことなく、且つ効率的な顕微鏡観察診療を実施することができる。
特に、第２の発明に係る医療用診療装置おいて、前記固定支軸が、前記医療用診療台の側部に一体に固定された垂直支柱に設けられているものとした場合でも、医療用診療台による医療用顕微鏡装置への振動の影響が抑制されるから、医療用診療台及び医療用顕微鏡装置を含む医療用診療装置のシステム化を図る上で有効である。 Further, the fixed support shaft moves vertically on a vertical column that is erected on the medical table, a vertical column that is suspended from the ceiling of the clinic where the medical table is installed, and the floor of the clinic It can be provided on either a vertical support provided on a mobile equipment that is freely arranged, or an attachment member attached to the wall surface of the clinic. Therefore, the arrangement layout of the microscope apparatus can be set according to the specifications of the medical examination table and the clinic where it is installed. It is possible to carry out efficient microscopic observation medical treatment without frustration for the person.
In particular, in the medical medical device according to the second invention, even when the fixed support shaft is provided on a vertical support integrally fixed to a side portion of the medical medical table, Since the influence of the vibration on the medical microscope apparatus by the medical table is suppressed, it is effective in systematizing the medical medical device including the medical medical table and the medical microscope apparatus.

前記固定支軸１０及び接続部材１１の円筒部１１０のそれぞれの上端部は開口しており、この開口部より前記無影灯装置６のハンガーアーム６０の基部が嵌装され、水平旋回可能に支持されている。このハンガーアーム６０の支持構造の詳細についての説明は割愛する。また、固定支軸１０及び垂直支柱４０は、いずれも中空体であり、この中空部内には、前記無影灯６１の電源供給電線、更には顕微鏡本体３１による画像を電気的に処理して取り出す場合にはその伝送用電線等、が内装される。そして、これら電線は、接続部材１１及びハンガーアーム６０，３０内を経て、それぞれ、無影灯６１及び顕微鏡本体３１に配線接続される。 Next, details of the fitting connection structure between the fixed support shaft 10 and the connection member 11 will be described in detail with reference to FIGS. A hollow columnar fixed support shaft 10 is fixed to the upper end of the vertical support column 40 integrally. The connecting member 11 includes a cylindrical portion 110 that is concentrically fitted to the fixed support shaft 10 via rolling bearings 12 and 12, and a bracket portion 111 that supports the first arm 30a so as to be able to turn horizontally. The part 110 and the bracket part 111 are integrally connected in an inverted U shape when viewed from the front or side. Each of the rolling bearings 12 and 12 is formed of a single row of deep groove radial ball bearings, and is disposed in the upper and lower portions of the fitting portion of the cylindrical portion 110 with respect to the fixed support shaft 10 in the illustrated example. When there will be no detent member (brake member 13 and stopper member 14) to be described later, the connecting member 11 can be rotated around its axis with respect to the fixed support shaft 10 by means of the rolling bearings 12, 12. It is in a fitted state. As an anti-rotation member for preventing this rotation, a brake member 13 and a stopper member 14 are used in the illustrated example.
The upper end portions of the fixed support shaft 10 and the cylindrical portion 110 of the connecting member 11 are opened, and the base portion of the hanger arm 60 of the surgical lamp device 6 is fitted through the opening portion and supported so as to be horizontally rotatable. Has been. A detailed description of the support structure of the hanger arm 60 is omitted. The fixed support shaft 10 and the vertical support column 40 are both hollow bodies, and the power supply wire of the operating light 61 and the image by the microscope main body 31 are electrically processed and taken out in the hollow portion. In some cases, the transmission wires and the like are internally provided. These electric wires are wired and connected to the surgical lamp 61 and the microscope body 31 through the connection member 11 and the hanger arms 60 and 30, respectively.

ブレーキ部材１３は、図３、図４及び図５に示すように、筒状の六角穴付雄ねじ部材１３１と、該六角穴付雄ねじ部材１３１の先側の内筒部１３１ａに圧入一体とされる断面Ｔ字形の樹脂製ブレーキパッド部材１３２と、雄ねじ部材１３１とブレーキパッド部材１３２との間に圧縮状態で介在される１個の平ワッシャ１３３と、２個の皿ばね１３４，１３４とよりなる。前記接続部材１１の円筒部１１０の筒壁には、径方向の雌ねじ孔１１０ａが貫設され、前記雄ねじ部材１３１が、前記内筒部１３１ａに連通する六角穴１３１ｂに、六角レンチ（不図示）を作用させることによって、この雌ねじ孔１１０ａに螺合される。前記固定支軸１０の周面には、座ぐり加工によってフラット面１０１が形成され、前記雌ねじ孔１１０ａに雄ねじ部材１３１をして螺合されたブレーキ部材１３は、前記ブレーキパッド部材１３２を介してこのフラット面１０１に圧接された状態とされる。ブレーキパッド部材１３２のフラット面１０１に対する圧接に伴う樹脂部材特有の制動作用によって、接続部材１１の固定支軸１０に対する軸回転が阻止される。この圧接力は、雄ねじ部材１３１の雌ねじ孔１１０ａに対する螺合度合いによって調整され、従って、雄ねじ部材１３１及び雌ねじ孔１１０ａが、圧接度合いの調整手段として位置付けられる。また、前記２個の皿ばね１３４，１３４は、圧縮されることによりブレーキパッド部材１３２に圧縮反力によるフリクション機能を付与し、ブレーキパッド部材１３２の前記制動作用の発現がより的確になされる。 As shown in FIGS. 3, 4, and 5, the brake member 13 is press-fitted into a cylindrical hexagon socket male screw member 131 and an inner cylinder portion 131 a on the front side of the hexagon socket male screw member 131. The resin brake pad member 132 having a T-shaped cross section, one flat washer 133 interposed between the male screw member 131 and the brake pad member 132 in a compressed state, and two disc springs 134 and 134 are included. The cylindrical wall of the cylindrical part 110 of the connecting member 11 is provided with a female threaded hole 110a in the radial direction, and the male threaded member 131 is inserted into a hexagonal hole 131b communicating with the inner cylindrical part 131a. Is engaged with the female screw hole 110a. A flat surface 101 is formed on the peripheral surface of the fixed support shaft 10 by counterbore processing, and the brake member 13 screwed into the female screw hole 110a with a male screw member 131 is interposed via the brake pad member 132. The flat surface 101 is in pressure contact. The rotation of the connecting member 11 relative to the fixed support shaft 10 is prevented by the braking action specific to the resin member accompanying the pressure contact of the brake pad member 132 with the flat surface 101. This pressure contact force is adjusted by the degree of screwing of the male screw member 131 with respect to the female screw hole 110a. Therefore, the male screw member 131 and the female screw hole 110a are positioned as means for adjusting the pressure contact degree. Further, the two disc springs 134 and 134 are compressed to give the brake pad member 132 a friction function by a compression reaction force, so that the braking action of the brake pad member 132 is more accurately expressed.

ストッパ部材１４は、図３、図６及び図７に示すように、リング部材１４１と、該リング部材１４１を固定支軸１０に固定するための六角穴ボルト１４２と、リング部材１４１の外周に嵌装されるゴム製Ｏリング１４３とよりなる。リング部材１４１の周体にはＯリング溝１４１ａが形成され、Ｏリング１４３は、内径側部分がこのＯリング溝１４１ａに嵌り込んだ状態でリング部材１４１の外周に嵌装される。リング部材１４１の内筒部は、小径部１４１ｂと大径部１４１ｃとが同心的に連通してなり、小径部１４１ｂの内径は前記六角穴ボルト１４２の胴部１４２ａを遊挿し得るも、頭部１４２ｂを挿通し得ない大きさとされ、小径部１４１ｂは雌ねじ孔とされている。また、大径部１４１ｃの内径は、前記六角穴ボルト１４２の頭部１４２ｂの外径よりやや大とされている。接続部材１１の前記円筒部１１０には、径方向に貫通する透孔１１０ｂが形成されており、この透孔１１０ｂの内径は、前記リング部材１４１の外径よりやや大とされている。また、この透孔１１０ｂと対向する固定支軸１０の周面には、前記リング部材１４１の外径よりやや大きい内径の座ぐり部１０２が形成され、さらにこの座ぐり部１０２の底部中央には、前記六角穴ボルト１４２を螺合し得る雌ねじ孔１０３が形成されている。 As shown in FIGS. 3, 6 and 7, the stopper member 14 is fitted to the ring member 141, the hexagon socket bolt 142 for fixing the ring member 141 to the fixed support shaft 10, and the outer periphery of the ring member 141. And a rubber O-ring 143 to be mounted. An O-ring groove 141a is formed in the periphery of the ring member 141, and the O-ring 143 is fitted on the outer periphery of the ring member 141 in a state where an inner diameter side portion is fitted in the O-ring groove 141a. The inner cylindrical portion of the ring member 141 has a small diameter portion 141b and a large diameter portion 141c concentrically communicating with each other, and the inner diameter of the small diameter portion 141b can be loosely inserted into the body portion 142a of the hexagon socket bolt 142. The small diameter portion 141b is a female screw hole. The inner diameter of the large-diameter portion 141c is slightly larger than the outer diameter of the head 142b of the hexagon socket bolt 142. The cylindrical portion 110 of the connecting member 11 is formed with a through hole 110 b that penetrates in the radial direction. The inner diameter of the through hole 110 b is slightly larger than the outer diameter of the ring member 141. Further, a counterbore 102 having an inner diameter slightly larger than the outer diameter of the ring member 141 is formed on the peripheral surface of the fixed support shaft 10 facing the through hole 110b. A female screw hole 103 into which the hexagon socket bolt 142 can be screwed is formed.

このように構成されたストッパ部材１４は、前記Ｏリング１４３を装着したリング部材１４１を、前記透孔１１０ｂにＯリング１４３が圧縮された状態で圧入し、前記六角穴ボルト１４２を、リング部材１４１の内筒部に挿通し、六角穴１４２ｃに六角レンチ（不図示）を作用させて前記雌ねじ孔１０３に螺合することによって固定される。この固定状態では、リング部材１４１の先端部が前記座ぐり部１０２に嵌り込み、ストッパ部材１４が接続部材１１と固定支軸１０とに跨った状態とされ、これによって、接続部材１１の固定支軸１０に対する軸回転が阻止される。そして、ストッパ部材１４のこのような装着状態では、リング部材１４１と接続部材１１の前記透孔１１０ｂとの間にＯリング１４３が圧縮された状態で介在する。従って、Ｏリング１４３が防振ゴムの役割を果たし、固定支軸１０からの振動がストッパ部材１４を介して接続部材１１に伝達することが防止される。
ストッパ部材１４を取外す際は、先ず、六角穴ボルト１４２を緩めて取り出すが、この状態では、前記Ｏリング１４３のフリクション力が作用しており、リング部材１４１はまだ透孔１１０ｂに保持された状態とされる。そのため、前記雌ねじ孔１４１ｂと同径の雄ねじ部材（不図示）を、該前記雌ねじ孔１４１ｂに螺合させ、その先端を前記座ぐり部１０２に当接させ、前記フリクション力を超える反作用力によって、リング部材１４１を雄ねじ部材と共に取り出すことできる。 The stopper member 14 configured as described above press-fits the ring member 141 with the O-ring 143 attached thereto in a state where the O-ring 143 is compressed into the through-hole 110b, and the hexagon socket bolt 142 to the ring member 141. It is fixed by being inserted into the inner cylinder portion and screwed into the female screw hole 103 by applying a hexagon wrench (not shown) to the hexagonal hole 142c. In this fixed state, the tip end portion of the ring member 141 is fitted into the counterbore portion 102, and the stopper member 14 straddles the connection member 11 and the fixed support shaft 10, whereby the fixed support of the connection member 11 is secured. Shaft rotation with respect to the shaft 10 is prevented. In such a mounted state of the stopper member 14, the O-ring 143 is interposed between the ring member 141 and the through hole 110 b of the connection member 11 in a compressed state. Therefore, the O-ring 143 serves as a vibration isolating rubber, and vibration from the fixed support shaft 10 is prevented from being transmitted to the connection member 11 via the stopper member 14.
When removing the stopper member 14, first, the hexagon socket bolt 142 is loosened and taken out. In this state, the frictional force of the O-ring 143 is acting, and the ring member 141 is still held in the through hole 110b. It is said. Therefore, a male screw member (not shown) having the same diameter as that of the female screw hole 141b is screwed into the female screw hole 141b, the tip thereof is brought into contact with the counterbore portion 102, and the reaction force exceeding the friction force is The ring member 141 can be taken out together with the male screw member.

前記のような支持構造の歯科用顕微鏡装置３を備えた歯科用診療装置１においては、無影灯装置６を操作したり、アシスタント側のインスツルメントホルダ９を引き出し、或いは、アシスタント用インスツルメント９１を取り出し（ピックアップ）したりすると、垂直支柱４０及び固定支軸１０に振動が発生する。而して、垂直支柱４０と歯科用顕微鏡装置３との間には、前記のような固定支軸１０と接続部材１１との嵌装接続構造が存在するから、垂直支柱４０及び固定支軸１０の振動は、前記深溝ラジアル玉軸受（転がり軸受）１２によって遮断され、接続部材１１への伝達が抑制される。従って、歯科用顕微鏡装置３の顕微鏡本体３１には振動が至らず、顕微鏡本体３１による正常な顕微鏡観察を実施することができる。また、固定支軸１０と接続部材１１とには、ブレーキ部材１３及びストッパ部材１４による回り止め部材が設けられているから、接続部材１１が固定支軸１０に対して軸回転することなく支持される。そして、接続部材１１に装着されるブレーキ部材１３が固定支軸１０の周面に圧接されるから、そのフリクション作用によって、固定支軸１０の振動が接続部材１１に直接伝わらず、特に、樹脂からなるブレーキパッド部材１３２と、圧縮状態の皿ばね１３４の存在により、フリクション作用がより効果的に発現される。加えて、ストッパ部材１４が、接続部材１１と固定支軸１０とに跨るように装着されているから、接続部材１１の固定支軸１０に対する軸回転が確実に阻止される。また、Ｏリング１４３が接続部材１１との装着部との間に弾性緩衝部材として介在するから、前記ブレーキ部材１３のフリクション作用とも相俟って、前記垂直支柱４０からの振動があった場合や、顕微鏡本体３１を手で操作し被写体の位置に位置付ける場合等において、顕微鏡本体３１がガタツキ等を生じず、速やかに静止し、顕微鏡観察診療の効率化が図られる。
尚、本実施形態では、回り止め部材として、ブレーキ部材１３及びストッパ部材１４を併用しているが、どちらか一方を用いるようにしても良い。 In the dental medical device 1 including the dental microscope device 3 having the support structure as described above, the surgical light device 6 is operated, the instrument holder 9 on the assistant side is pulled out, or the instrument for assistant is used. When the ment 91 is taken out (pick up), vibration occurs in the vertical support column 40 and the fixed support shaft 10. Thus, since there is a fitting connection structure between the fixed support shaft 10 and the connecting member 11 between the vertical support column 40 and the dental microscope apparatus 3, the vertical support column 40 and the fixed support shaft 10. Is blocked by the deep groove radial ball bearing (rolling bearing) 12 and transmission to the connecting member 11 is suppressed. Therefore, the microscope main body 31 of the dental microscope apparatus 3 does not vibrate, and normal microscope observation with the microscope main body 31 can be performed. Further, since the fixed support shaft 10 and the connection member 11 are provided with a rotation preventing member by the brake member 13 and the stopper member 14, the connection member 11 is supported without rotating about the fixed support shaft 10. The And since the brake member 13 with which the connection member 11 is mounted is press-contacted with the peripheral surface of the fixed support shaft 10, the vibration of the fixed support shaft 10 is not directly transmitted to the connection member 11 due to the friction action, and particularly from resin. The friction action is more effectively expressed by the presence of the brake pad member 132 and the disk spring 134 in the compressed state. In addition, since the stopper member 14 is mounted so as to straddle the connection member 11 and the fixed support shaft 10, the shaft rotation of the connection member 11 with respect to the fixed support shaft 10 is reliably prevented. In addition, since the O-ring 143 is interposed as an elastic buffer member between the mounting portion and the connecting member 11, there is a vibration from the vertical column 40 in combination with the friction action of the brake member 13. When the microscope main body 31 is operated by hand and positioned at the position of the subject, the microscope main body 31 does not rattle or the like and quickly stops and the efficiency of microscope observation medical care is improved.
In this embodiment, the brake member 13 and the stopper member 14 are used in combination as the rotation preventing member, but either one may be used.

図８は、回り止め部材の他の実施形態を示している。即ち、本実施形態の回り止め部材はストッパ機能部をさらに備えたブレーキ部材１５からなる。該ブレーキ部材１５の主たる構成は、前記ブレーキ部材１３とほぼ同様であり、六角穴１５１ｂを有する筒状の雄ねじ部材１５１と、該六角穴雄ねじ部材１５１の先側の内筒部１５１ａに圧入一体とされる樹脂製のブレーキパッド部材１５２と、雄ねじ部材１５１とブレーキパッド部材１５２との間に圧縮状態で介在される１個の平ワッシャ１５３と、３個の皿ばね１５４…とよりなる。そして、ブレーキパッド部材１５２の先端部、平ワッシャ１５３、及び皿ばね１５４のそれぞれの外径を、前記例のブレーキパッド部材１３２の先端部、平ワッシャ１３３、及び皿ばね１３４のそれぞれの外径より大としている。また、固定支軸１０の周面には、前記雄ねじ部材１５１の外径よりやや大きい内径の座ぐり部１０３が底面がフラットになるよう形成され、前記雄ねじ部材１５１の先端部１５１ｃが嵌り込み得るようになされている。これによってストッパ機能部を構成する。更に、ブレーキパッド部材１５２の先端部表面には、セレーションのような細かな凹凸加工１５２ａが施されている。その他の構成は、前記ブレーキ部材１３と同様である。 FIG. 8 shows another embodiment of the detent member. That is, the detent member of the present embodiment includes the brake member 15 further provided with a stopper function unit. The main structure of the brake member 15 is substantially the same as that of the brake member 13, and is integrally formed with a cylindrical male screw member 151 having a hexagonal hole 151b and an inner cylindrical portion 151a on the front side of the hexagonal hole male screw member 151. The brake pad member 152 made of resin, one flat washer 153 interposed between the male screw member 151 and the brake pad member 152 in a compressed state, and three disc springs 154. Then, the outer diameters of the distal end portion of the brake pad member 152, the flat washer 153, and the disc spring 154 are made larger than the outer diameters of the distal end portion of the brake pad member 132, the flat washer 133, and the disc spring 134 of the example. It ’s big. Further, a counterbore portion 103 having an inner diameter slightly larger than the outer diameter of the male screw member 151 is formed on the peripheral surface of the fixed spindle 10 so that the bottom surface is flat, and the tip portion 151c of the male screw member 151 can be fitted. It is made like that. This constitutes a stopper function part. Further, the surface of the tip of the brake pad member 152 is provided with a fine unevenness 152a such as serration. Other configurations are the same as those of the brake member 13.

このようなブレーキ部材１５は、前記と同様に接続部材１１の円筒部１１０に形成された雌ねじ孔１１０ａに雄ねじ部材１５１を螺合することによって装着され、基本的には前記ブレーキ部材１３と同様の機能を奏する。この例のブレーキ部材１５は、雄ねじ部材１５１の先端部１５１ｃがこれよりやや径大の座ぐり部１０３に嵌り込むことによって、接続部材１１と固定支軸１０とに跨って装着されることになり、これによってストッパ機能も奏する。また、ブレーキパッド部材１５２の先端部の外径が前記ブレーキパッド部材１３２の外径より大きく、加えて、ブレーキパッド部材１５２の表面に凹凸加工１５２ａが施されていることにより、座ぐり部１０３の底面に対する圧接による制動作用もより強く発揮される。更に、皿ばね１５４が前記例より多く組み込まれていることにより、前記フリクション作用もより効果的に発現される。この例の場合も、ブレーキパッド部材１５２の前記座ぐり部１０３の底面に対する圧接力は、雄ねじ部材１５１の雌ねじ孔１１０ａに対する螺合度合いによって調整され、従って、雄ねじ部材１５１及び雌ねじ孔１１０ａが、圧接度合いの調整手段として位置付けられる。
Such a brake member 15 is mounted by screwing a male screw member 151 into a female screw hole 110a formed in the cylindrical portion 110 of the connecting member 11 in the same manner as described above, and is basically the same as the brake member 13 described above. The function is played. The brake member 15 in this example is mounted across the connection member 11 and the fixed support shaft 10 by fitting the tip portion 151c of the male screw member 151 into the counterbore portion 103 having a slightly larger diameter. This also provides a stopper function. Further, the outer diameter of the front end portion of the brake pad member 152 is larger than the outer diameter of the brake pad member 132, and in addition, the surface of the brake pad member 152 is provided with a concavo-convex process 152a. The braking action by pressure contact with the bottom surface is also exerted more strongly. Furthermore, since the disc spring 154 is incorporated in a larger amount than in the above example, the friction action is more effectively expressed. Also in this example, the pressing force of the brake pad member 152 against the bottom surface of the counterbore 103 is adjusted by the degree of screwing of the male screw member 151 with respect to the female screw hole 110a. It is positioned as a means for adjusting the degree.

図９は、前記ブレーキ部材１５を用いた場合の固定支軸１０と接続部材１１との嵌装接続構造の一例を示す分解図である。この例では、回り止め部材としてストッパ機能を備えたブレーキ部材１５のみを用い、前記例の深溝ラジアル玉軸受１２よりスラスト方向に長い複数列の深溝ラジアル玉軸受（或いは、針状ころ軸受）１２Ａを１個用いている。この例でも、固定支軸１０と接続部材１１との嵌装接続関係による作用効果が同様に発揮される。このような深溝ラジアル玉軸受（或いは、針状ころ軸受）１２Ａは、スラスト方向の幅広い範囲で前記のような振動遮断機能を奏するもので、図３の例で、回り止め部材として、ブレーキ部材１３及びストッパ部材１４のどちらか一方のみを採用する場合にも用いることができる。 FIG. 9 is an exploded view showing an example of a fitting connection structure between the fixed support shaft 10 and the connection member 11 when the brake member 15 is used. In this example, only the brake member 15 having a stopper function is used as a detent member, and a plurality of rows of deep groove radial ball bearings (or needle roller bearings) 12A that are longer in the thrust direction than the deep groove radial ball bearing 12 of the above example. One is used. Also in this example, the effect by the fitting connection relationship between the fixed support shaft 10 and the connection member 11 is similarly exhibited. Such a deep groove radial ball bearing (or needle roller bearing) 12A exhibits the above-described vibration isolation function in a wide range in the thrust direction. In the example of FIG. Also, it can be used when only one of the stopper member 14 and the stopper member 14 is employed.

図１０は、歯科用顕微鏡装置３の第２の実施形態を示し、固定支軸１０が、診療台が設置される診療室の天井Ｔから垂下される垂直支柱４０Ａに設けられ、この固定支軸１０に接続部材１１が嵌装接続されている。この場合、接続部材１１は固定支軸１０に対して、前記と同様の上下の深溝ラジアル玉軸受１２，１２を介して下から嵌装される。接続部材１１の脱落を防止するため、接続部材１１が固定支軸１０に嵌装された状態で支持ナット１１２が、固定支柱１０の下端に形成された雄ネジ部１０４に螺合されている。そして、歯科用顕微鏡装置３を構成するハンガーアーム３０が、前記と同様に接続部材１１に水平旋回可能に支持され、診療台上の患者の患部を観察し得る位置に顕微鏡本体３１を位置付けることが可能とされている。また、接続部材１１と固定支軸１０との嵌装接続構造においては、図２及び図３に示す例と同様の回り止め部材（ブレーキ部材１３及びストッパ部材１４）によって接続部材１１の固定支軸１０に対する軸回転が防止されるよう構成されている。従って、接続部材１１及び固定支軸１０には、これらブレーキ部材１３及びストッパ部材１４に関係する雌ねじ孔１１０ａ、透孔１１０ｂ、座ぐり部１０１，１０２も同様に形成されている。このように天井Ｔに歯科用顕微鏡装置３が取付けられている場合、エアコンその他の機器の振動が、垂直支柱４０Ａを介して固定支軸１０に伝達されるが、固定支軸１０と接続部材１１との前記と同様の嵌装接続構造によって、歯科用顕微鏡装置３に対する振動の伝達が前記と同様に抑制される。
歯科用顕微鏡装置３のその他の構成は前記例と同様であるので、共通部分に同一の符号を付して、その説明及び一部図示を省略する。また、図例では、無影灯を垂直支柱４０Ａに支持させていないが、支持させるよう構成しても良い。 FIG. 10 shows a second embodiment of the dental microscope apparatus 3, and the fixed support shaft 10 is provided on a vertical support 40A suspended from the ceiling T of the clinic where the medical table is installed, and this fixed support shaft. A connecting member 11 is fitted and connected to 10. In this case, the connection member 11 is fitted to the fixed support shaft 10 from below via the same upper and lower deep groove radial ball bearings 12 and 12 as described above. In order to prevent the connection member 11 from falling off, the support nut 112 is screwed into a male screw portion 104 formed at the lower end of the fixed column 10 with the connection member 11 fitted on the fixed support shaft 10. And the hanger arm 30 which comprises the dental microscope apparatus 3 is supported by the connection member 11 so that horizontal rotation is possible like the above, and the microscope main body 31 can be positioned in the position which can observe the affected part of the patient on a medical table. It is possible. Moreover, in the fitting connection structure of the connection member 11 and the fixed support shaft 10, the fixed support shaft of the connection member 11 is provided by the same non-rotating member (the brake member 13 and the stopper member 14) as in the example shown in FIGS. 10 is configured to prevent shaft rotation with respect to 10. Accordingly, the connection member 11 and the fixed support shaft 10 are similarly formed with female screw holes 110a, through holes 110b, and counterbore portions 101 and 102 related to the brake member 13 and the stopper member 14. In this way, when the dental microscope apparatus 3 is attached to the ceiling T, the vibrations of the air conditioner and other devices are transmitted to the fixed support shaft 10 via the vertical support column 40A, but the fixed support shaft 10 and the connection member 11 are transmitted. As described above, the transmission of vibration to the dental microscope apparatus 3 is suppressed in the same manner as described above.
