この考案は、歯科用などの小容量のＸ線装置において、そのＸ線管球および高 電圧変圧器を同じ容器内に収めた密閉式Ｘ線発生器を自在アームに結合したり、 または分離して携帯用Ｘ線装置として用いるに当り、その結合・分離を司るＸ線 発生器装着脱装置に関する。 In this invention, in a small-capacity X-ray device for dentistry or the like, a sealed X-ray generator, in which the X-ray tube and a high-voltage transformer are housed in the same container, is connected to or separated from a universal arm. When used as a portable X-ray device, the present invention relates to an X-ray generator attachment / detachment device that controls the coupling / separation thereof.
【０００２】[0002]
従来の歯科用またはそれに準ずる小容量Ｘ線装置は、密閉式Ｘ線発生器とも呼 ばれＸ線管球と同じ容器内に高電圧変圧器を収めてこれを結ぶケーブルをなくし 、台車付保持器などの自在アームの先端に吊下支承された状態で使用されるもの である。したがって重量の大きい変圧器類をはじめ管球その他あらゆる構成部品 にわたり小形軽量化を図る工夫は従来から盛んに行われ、その定格容量に対応し て形状・重量とも最小と考えられるＸ線発生器が作られ広く用いられている。筆 者らも上記小形軽量化に対する研究開発に努力した結果、出願し既に登録されて いる「特許第１４２５９４０号］の「携帯形Ｘ線発生器」に示す発明は、容量が 大きく加熱変圧器を必要とするＸ線発生器において、管球を加熱変圧器の独創的 な外鉄形鉄心内に包容することによってＸ線発生器を小形軽量化したものであり 、このＸ線発生器に比し小容量の歯科用またはそれに準ずるＸ線装置においては 、単相自己整流および同時点火方式を採用しうるので、上記加熱変圧器が不要で あり、その分Ｘ線発生器が小形軽量化される。さらに小形軽量化する対象は高電 圧変圧器であるが、これに対しては近年急速に普及した半導体技術によるインバ ータを採用し、かつその入力波形を高周波とすれば、高電圧変圧器の鉄心実断面 積が減少するという原理にもとづき、たとえば１ＫＨｚの入力とすれば、鉄心の 総重量が約１／２に軽量化されるのである。このようにして小容量のＸ線発生器 は従来品に比して超小形軽量化されるものとなった。しかしながら上記の如く小 形軽量化されたＸ線発生器を有するＸ線装置も自在アームなどに恒久的に保持さ れた状態にては、たとえば身体障害者や寝たきり老人などの在宅診療、あるいは 僻地診療または飛行機事故などの際の法医学的な個体認識のためのＸ線撮影が不 可能である。これらのＸ線撮影を可能とする携帯用Ｘ線装置すなわち上記Ｘ線発 生器を自在アームなどの保持器から容易な操作で分離し、Ｘ線制御器とともに携 帯用として使用可能なＸ線装置の開発が強く要望される現況である。 A conventional dental or similar small-capacity X-ray device is also called a closed X-ray generator. A high-voltage transformer is housed in the same container as the X-ray tube and the cable connecting it is eliminated, and the cage with a trolley It is used by being suspended and supported on the tip of a free arm. Therefore, many efforts have been made to reduce the size and weight of heavy-weight transformers, tubes, and all other components, and an X-ray generator that is considered to have the smallest shape and weight according to its rated capacity has been developed. Made and widely used. As a result of efforts by the authors in research and development for reducing the size and weight, the invention shown in the “portable X-ray generator” of “Patent No. 1425940”, which has been filed and already registered, has a large capacity and requires a heating transformer. In the required X-ray generator, the X-ray generator was made smaller and lighter by enclosing the tube in the original outer iron core of the heating transformer, and compared with this X-ray generator. In a small-capacity dental or equivalent X-ray apparatus, since the single-phase self-rectification and simultaneous ignition method can be adopted, the above heating transformer is unnecessary, and the X-ray generator can be reduced in size and weight accordingly. High-voltage transformers are targeted for further size reduction and weight reduction.However, high-voltage transformers can be used by adopting an inverter based on semiconductor technology that has rapidly spread in recent years and by using a high-frequency input waveform. Based on the principle that the actual cross-sectional area of the iron core is reduced, if the input is 1 KHz, the total weight of the iron core is reduced to about 1/2. In this way, the small-capacity X-ray generator has become ultra-compact and lightweight compared to conventional products. However, as described above, when the X-ray device having the compact and lightweight X-ray generator is permanently held by the universal arm or the like, for example, home care for a physically handicapped person or a bedridden elderly person, or a remote area. It is impossible to perform X-ray imaging for forensic individual recognition at the time of medical treatment or airplane accident. A portable X-ray device that enables these X-ray photography, that is, an X-ray that can be used as a mobile phone together with an X-ray controller by separating the X-ray generator from a holder such as a free arm by an easy operation. This is the current state of strong demand for device development.

It is an object to separate the generator from the free arm such as a cage with a trolley at any time by an easy operation so that it can be used as a portable X-ray device together with the X-ray controller.

以下この考案の実施例を図面を参照して説明する。図１はこの考案にかかるＸ 線発生器装着脱装置（１）によって、Ｘ線ヘッド（２）をたとえば移動型自在ア ーム（３）に結合してなる歯科用Ｘ線装置（４）の外観斜視図である。一般に用 いられている歯科用Ｘ線装置（４）の自在アーム（３）は図示の移動型に限らず 、床取付型、壁取付型、または天井取付型などいろいろあるが、自在アーム（３ ）の機能は何れも同じである。すなわちツーアーム（３Ａ）（３Ｂ）の開脚角度 が自在であるとともに、各関節部の回転自在角は１８０°ないし３６０°であり 、Ｘ線ヘッド（２）の操作性はきわめて良い。図において（５）はキヤスター付 き台車、（６）は装置主柱、（７）はＸ線制御器であり、このＸ線制御器（７） とＸ線ヘッド（２）とを接続するケーブルは図示を省略した。つぎに図２および 図３によってＸ線ヘッド（２）を説明する。図２はその側面外観図、図３は背面 図であるが、内部構造を示すため、右半面は内・外容器を除き、かつ管球部は鉛 遮へい壁を一部破裁している。Ｘ線ヘッド（２）は商用電源１００Ｖで１ＫＶＡ の出力を有するたとえば歯科用Ｘ線装置のＸ線ヘッドであり、図２に示すＸ線放 射筒（８）を含む全長（Ｄ）は１８８ｍｍで、図３に示す幅（Ｗ）は１４７ｍｍ 、高さ（Ｈ）は１５４ｍｍの小形である。Ｘ線ヘッド（２）に内蔵している管球 （９）は、たとえば固定陽極型０．８ｍｍ焦点診察用の外径約３０ｍｍ、長さ約 ８０ｍｍの小形のものであり、同じく内蔵している高電圧変圧器（１０）は１次 コイル（１２）および２次コイル（１３）をともにロの字形閉磁路鉄心（１４） に巻いている。従来の技術の項で述べたとおり、小容量のこのＸ線ヘッド（２） にては線条加熱変圧器が不要であるので、その分軽量化されているだけでなく、 高電圧変圧器（１０）の入力電圧をインバータを介してたとえば１ＫＨｚの高周 波に変調しているため、鉄心（１４）の断面積が小さく、したがって鉄心全重量 が従来のものに比し約１／２に軽量化されている。なお図において、（１５）は Ｘ線曝射押釦スイッチ、（１６）はＸ線照射確認灯であり、Ｘ線照射中点灯して いる。（１７）は管球鉛遮へい円筒であり、図示できないがＸ線照射口に対応す る孔があけてある。（１８）はＸ線ヘッド内容器で管球（９）および高電圧変圧 器（１０）を内蔵し、かつそれらを絶縁ならびに冷却する変圧器油を密封してい る。なお、内容器（１８）の上部すなわち管球（９）の周辺には漏洩Ｘ線防止の 鉛板を張り付けている。（１９）はＸ線ヘッド外容器で、合成樹脂で成型されて いる。（２０）は前記内容器（１８）と、外容器（１９）とに緊締固着され、あ とで述べるＸ線ヘッド側面に設ける円筒部材Ａ（２３）を固着する基台である。 以上がＸ線ヘッド（２）の構成であり、全重量が約３Ｋｇに超小形軽量化された ものである。 つぎに再び図１にもどって、Ｘ線装置（４）として上記Ｘ線ヘッド（２）とと もに不可欠のＸ線制御器（７）について簡単に説明する。このＸ線装置（４）は 管電圧および管電流をたとえば６０ＫＶ、１０ｍＡに固定しておき、Ｘ線照射時 間のみを調整するようにしており、したがってＸ線制御器（７）はごく簡単な手 箱式であり、その盤面（７Ｆ）には商用電源スイッチとタイマーの時間設定ＵＰ ．ｄｏｗｎの２個の押釦スイッチおよび設定時間表示部が設けられ、Ｘ線照射時 間をたとえば０．１〜３．３ｓｅｃの範囲で０．１ｓｅｃ単位で自在に選択設定 できる。なおＸ線曝射押釦およびＸ線照射確認灯がＸ線ヘッド（２）と同様に設 けられており、Ｘ線曝射をＸ線ヘッドまたはＸ線制御器いずれにても行えるよう にしている。このＸ線制御器（７）の内部には、前述した主変圧器用のインバー タや、上記設定時間表示用の発光ダイオードアレイその他装置全体の制御電子回 路および器材が収容されている。以上がＸ線制御器（７）の構成であり、これも 全重量が約３Ｋｇとまとめて軽量化されている。 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a dental X-ray device (4) comprising an X-ray generator mounting / demounting device (1) according to the present invention, in which an X-ray head (2) is connected to, for example, a movable arm (3). FIG. The universal arm (3) of the commonly used dental X-ray device (4) is not limited to the movable type shown in the figure, but there are various types such as a floor mount type, a wall mount type, or a ceiling mount type. ) Have the same function. That is, the leg opening angle of the two arms (3A) (3B) is freely adjustable, and the rotatable angle of each joint is 180 ° to 360 °, and the operability of the X-ray head (2) is extremely good. In the figure, (5) is a carriage with a caster, (6) is a main pillar of the device, and (7) is an X-ray controller. A cable connecting the X-ray controller (7) and the X-ray head (2). Are not shown. Next, the X-ray head (2) will be described with reference to FIGS. Fig. 2 is a side view of the side view, and Fig. 3 is a rear view. To show the internal structure, the right-half surface excludes the inner and outer containers, and the bulb part partially cuts the lead shielding wall. The X-ray head (2) is, for example, an X-ray head of a dental X-ray device having a commercial power supply of 100 V and an output of 1 KVA, and the total length (D) including the X-ray emission tube (8) shown in FIG. 2 is 188 mm. The width (W) shown in FIG. 3 is 147 mm, and the height (H) is 154 mm. The tube (9) contained in the X-ray head (2) is, for example, a small type with a fixed anode type 0.8 mm outer diameter of about 30 mm and a length of about 80 mm for focus diagnosis. The high voltage transformer (10) has a primary coil (12) and a secondary coil (13) both wound around a square-shaped closed magnetic circuit core (14). As mentioned in the section of the prior art, since the X-ray head (2) with a small capacity does not require a wire heating transformer, not only is it lighter in weight, but also a high voltage transformer ( Since the input voltage of 10) is modulated to a high frequency of, for example, 1 KHz via the inverter, the cross-sectional area of the iron core (14) is small, and therefore the total weight of the iron core is about 1/2 the weight of the conventional one. Has been converted. In the figure, (15) is an X-ray irradiation push button switch, and (16) is an X-ray irradiation confirmation lamp, which is lit during X-ray irradiation. (17) is a tube lead shield cylinder, which has a hole corresponding to the X-ray irradiation port, which is not shown. (18) is a container in the X-ray head, which contains a tube (9) and a high-voltage transformer (10) and seals transformer oil for insulating and cooling them. A lead plate for preventing leaked X-rays is attached to the upper part of the inner container (18), that is, around the tube (9). (19) is an X-ray head outer container, which is molded of synthetic resin. (20) is a base which is tightly fixed to the inner container (18) and the outer container (19) and to which a cylindrical member A (23) provided on the side surface of the X-ray head described later is fixed. The above is the configuration of the X-ray head (2), which is ultra-compact and lightweight with a total weight of about 3 kg. Next, returning to FIG. 1 again, the X-ray controller (7) which is indispensable together with the X-ray head (2) as the X-ray apparatus (4) will be briefly described. In this X-ray device (4), the tube voltage and the tube current are fixed at, for example, 60 KV and 10 mA, and only the X-ray irradiation time is adjusted. Therefore, the X-ray controller (7) is very simple. It is a hand-held box type, and the panel surface (7F) has a commercial power switch and a timer setting UP. Two down pushbutton switches and a set time display section are provided, and the X-ray irradiation time can be freely selected and set in units of 0.1 sec within a range of 0.1 to 3.3 sec, for example. An X-ray irradiation push button and an X-ray irradiation confirmation lamp are provided in the same manner as the X-ray head (2), and X-ray irradiation can be performed by either the X-ray head or the X-ray controller. . Inside the X-ray controller (7), the above-mentioned inverter for the main transformer, the light-emitting diode array for displaying the set time and other control electronic circuits and equipment of the entire apparatus are housed. The above is the configuration of the X-ray controller (7), and the total weight of the X-ray controller (7) is also reduced to about 3 kg.
【０００７】 ここで図４、図５を用いてこの考案の要部であるＸ線発生器装着脱装置（１） の実施例を詳細に説明する。図４はＸ線ヘッド（２）の右側面に、自在アーム（ ３）の尖端に設けたハンガー接続部を装着した状態を示す装着脱装置（１）の現 寸大の断面図、図５は図４のＶ−Ｖ′断面図である。図４において、Ｘ線ヘッド の外容器（１９）の右側面にＬ字状台座（２３Ｂ）と一体的な円筒部材Ａ（２３ ）を、図３で説明した基台（２０）中央の雌捻子に螺合する雄捻子を有するとと もに六角頭部の長いボルト（２４）を介して緊締固着する。このボルト（２４） の緊締固着によって上記Ｌ字状台座の折曲部（２３ＢＦ）はヘッド外容器（１９ ）の底面（１９Ｂ）を包持し、上記ボルト（２４）と併せて円筒部材Ａ（２３） の固着を堅固にする。この円筒部材Ａ（２３）の頂部所定位置の全周に、たとえ ば幅５ｍｍ、深さ２ｍｍのキー溝（２５）が削設され、かつ円筒部材Ａ（２３） の内径と、自在アーム（３）の尖端に設けたハンガー接続部の円筒体Ｂ（２６） の内腔に樹設された円筒軸Ｃ（２７）の外径とをしつくりとはまり合うように、 「スキマバメ」の許容差で仕上げる。したがって前記円筒部材Ａ（２３）と円筒 軸Ｃ（２７）の嵌合精度がこの装置（１）の装着脱の操作性を左右することとな る。つぎに図５に示すキー部材（２８）は、その一端をハンガー円筒体Ｂ（２６ ）に蝶着し、他端（２８Ｔ）を円筒体Ｂ（２６）外に突出させるとともに、一端 をビス（２９）を介してキー部材（２８）に、他端を自在アーム（３）尖端部の 段部に係止された板ばね（３０）の弾撥力を介して、キー部材（２８）を円筒部 材Ａ（２３）のキー溝（２５）にはめ込みかつ圧接する。このキー部材（２８） がキー溝（２５）にはまり込んだ状態がＸ線ヘッド（２）を装着脱装置（１）に よって自在アーム（３）に対し回転自在に完全に結合された状態を示し、自在ア ーム（３）による任意の位置ぎめを行うたとえば歯科用Ｘ線装置（４）となる。 つぎにＸ線ヘッド（２）を自在アーム（３）から取外し、Ｘ線制御器（７）とと もに収納ケースに入れて持ち運び、僻地診療などを行うばあいは、図５で示した ハンガー外部に突出したキー部材の一端（２８Ｔ）を指で押し上げ、キー部材（ ２８）をキー溝（２５）の拘束を解放し、Ｘ線ヘッド（２）の円筒部材Ａ（２３ ）をハンガーの円筒軸Ｃ（２７）との嵌合から抜出せば、Ｘ線ヘッド（２）は自 在アーム（３）から完全に分離できる。この分離したＸ線ヘッド（２）は前述し たとおり、超小形軽量化され重量は約３Ｋｇで、Ｘ線制御器（７）も同じく約３ Ｋｇであるので、付属品などと共に収納ケースに入れ約９Ｋｇと軽く持ち運び簡 単で、商用電源が存在するところならどんなところでもＸ線撮影ができる便宜な 装置となる。 つぎに請求項２に示す実施例装置について図４、図５によって説明する。図４ に示す六角頭部の長いボルト（２４）の頭部（２４Ｈ）に捻子部の深さがたとえ ば８ｍｍのねじ径６ｍｍの雌捻子（３２）が削設されている。この雌捻子（３２ ）は図示しないカメラ用三脚の保持器に設けてある雄捻子と螺合するものである 。したがってＸ線ヘッド（２）を上記カメラ用三脚と結合させ三脚を自在に調整 して被写体に適応する位置ぎめを行うことが可能であり、Ｘ線ヘッド（２）を術 者が手で持って位置ぎめするのに比し、位置ぎめ操作がやり易すくなる。 以上がこの考案にかかる第一、第二の実施例装置の説明であるが、この考案は 図示や説明に限定されるものでないことはいうまでもない。An embodiment of the X-ray generator mounting / demounting device (1), which is a main part of the present invention, will be described in detail with reference to FIGS. 4 and 5.
