Description

Ｘ線透視撮影台X-ray fluoroscopy table
　本発明は、被検者寝載用天板（寝台）並びに被検者の撮影部位を圧迫するための圧迫筒装置とを備えたＸ線透視撮影台に関する。 The present invention relates to an X-ray fluoroscopic imaging table provided with a subject couch (bed) and a compression cylinder device for pressing an imaging region of the subject.
　一般に、被検者寝載用天板を備えたＸ線透視撮影台において、天板上に横たわる被検者の胃や腸などの臓器を撮影する場合、胃を他の臓器と区別して識別する必要があるため、バリウム系の造影剤を被検者に経口投与して撮影が行われるが、胃や腸は内壁にひだがあるため造影剤が均一に分散されにくく、このため、特許文献１や特許文献２に示すような圧迫筒を使用して撮影部位を上部から圧迫し、造影剤を胃壁などの隅々まで行き渡らせて透視撮影を行っている。また、圧迫撮影を行わないときは圧迫筒を、支柱に取り付けた格納箱内に格納できる構造となっている。
特開平１０－１０８８６３号公報 特開２００６－８１７８５号公報 In general, in an X-ray fluoroscopic table equipped with a subject-mounted top plate, when imaging an organ such as the stomach or intestine of a subject lying on the top plate, the stomach is identified and distinguished from other organs. Since it is necessary, imaging is performed by orally administering a barium-based contrast agent to a subject. However, since the stomach and intestine have folds on the inner wall, the contrast agent is difficult to be uniformly dispersed. In addition, the imaging part is pressed from above using a compression cylinder as shown in Japanese Patent Application Laid-Open No. H11-133, and the radiographic imaging is performed by spreading the contrast medium to every corner of the stomach wall. In addition, the compression cylinder can be stored in a storage box attached to a support column when pressure imaging is not performed.
Japanese Patent Laid-Open No. 10-108863 JP 2006-81785 A
　しかし、上記の従来構造では、圧迫筒を使用しないときに圧迫筒を格納箱内に格納したとしても、格納箱自体が、圧迫筒を駆動するためのモータやリンク等の駆動機構を内蔵し、かつ、圧迫筒を格納するに充分な内部空間を確保しなければならないので、かなり大きさサイズを必要とし、そのため、被検者が横たわる天板上の有効スペースを占領して術者の作業や被検者の寝起きの邪魔になる、といった大きな弊害があった。 However, in the above conventional structure, even when the compression cylinder is stored in the storage box when the compression cylinder is not used, the storage box itself incorporates a drive mechanism such as a motor or a link for driving the compression cylinder, In addition, since it is necessary to secure a sufficient internal space to store the compression cylinder, it requires a considerably large size, so that the operator can occupy the effective space on the top plate on which the subject lies and There was a major negative effect such as disturbing the subject's waking up.
　そこで本発明は、このような課題に鑑みてなされたものであって、被検者が横たわる際や術者が作業する際に、圧迫筒を収納する格納箱が邪魔にならないようにすることを目的とする。 Therefore, the present invention has been made in view of such problems, and it is intended to prevent the storage box for storing the compression cylinder from interfering when the subject lies down or when the operator works. Objective.
　上記目的を達成する為に本発明では次のような技術的手段を講じた。即ち、本発明のＸ線透視撮影台にあっては、Ｘ線管を上部で支持する支柱と、支柱前面側に配置された被検者寝載用天板と、被検者の撮影部位を圧迫するための圧迫筒と、前記支柱に取り付けられて圧迫筒を取り出し可能に格納する格納箱とを備えたＸ線透視撮影台において、前記圧迫筒の格納箱が格納箱回避機構を介して支柱前面に位置する使用位置から支柱側面に位置する回避位置に移動可能に形成するようにしている。 In order to achieve the above object, the present invention takes the following technical means. That is, in the X-ray fluoroscopic imaging table according to the present invention, a support column that supports the X-ray tube at the top, a subject-mounted top plate that is disposed on the front side of the support column, and an imaging region of the subject. An X-ray fluoroscopic table comprising a compression cylinder for compressing and a storage box that is attached to the column and stores the compression cylinder so that the compression cylinder can be taken out. The storage box of the compression cylinder is supported by a column through a storage box avoiding mechanism. It is configured to be movable from the use position located on the front surface to the avoidance position located on the side surface of the support column.
　本発明のＸ線透視撮影台は上記のごとく構成されているので、圧迫筒を必要としないときには格納箱回避機構を介して、圧迫筒を格納する格納箱を支柱側面に位置する回避位置まで回避させることができ、これにより、被検者が横たわる天板上の有効スペースを広く確保することができて格納箱が術者の作業や被検者の寝起きの邪魔になることを防止することができるといった優れた効果がある。 Since the X-ray fluoroscopic table of the present invention is configured as described above, when the compression cylinder is not required, the storage box for storing the compression cylinder is avoided to the avoidance position located on the side of the column via the storage box avoidance mechanism. As a result, it is possible to secure a wide effective space on the top board on which the subject lies, and to prevent the storage box from interfering with the operation of the operator or waking up the subject. There is an excellent effect that can be done.
（その他の課題を解決するための手段及び効果）
　上記発明において、前記格納箱回避機構は支柱に保持された蝶番部材を含み、該蝶番部材に圧迫筒の格納箱が取り付けられ、蝶番部材を回動することにより格納箱が使用位置と回避位置とに移動できるように形成されている構成とするのがよい。この場合、使用位置と回避位置で格納箱の姿勢を安定よく保持できるように、蝶番部材若しくは格納箱を支柱に対して仮止めするマグネットキャッチ等のキャッチ部材を設けてもよい。
　この構成によれば、圧迫筒を格納する格納箱の回避位置並びに使用位置への移動が、蝶番部材を介して格納箱を回動操作させるだけでよいから、操作が容易、迅速にでき、且つ簡単な構造で格納箱回避機構を形成することができる。 (Means and effects for solving other problems)
In the above invention, the storage box avoiding mechanism includes a hinge member held by a support, and a storage box of a compression cylinder is attached to the hinge member, and the storage box is moved between the use position and the avoidance position by rotating the hinge member. It is preferable to have a structure that can be moved. In this case, a catch member such as a magnet catch for temporarily fixing the hinge member or the storage box to the support column may be provided so that the attitude of the storage box can be stably held at the use position and the avoidance position.
According to this configuration, the storage box storing the compression cylinder can be moved to the avoidance position and the use position only by rotating the storage box via the hinge member. The storage box avoidance mechanism can be formed with a simple structure.
　また、上記発明において、前記格納箱回避機構が、支柱の周囲に設けられた円弧状のレールにと、該レールに沿って圧迫筒の格納箱が摺動できるように格納箱に設けられた嵌合溝とから構成するのがよい。
　これにより、圧迫筒を格納した格納箱を支柱に安定よく保持できると共に、格納箱をレールに沿って移動させることにより、回避位置並びに使用位置に容易に移動させることができ、かつ、簡単な構造で実現することができる。 Further, in the above invention, the storage box avoiding mechanism is fitted to the arc-shaped rail provided around the support column, and the storage box of the compression cylinder is slidable along the rail. It is good to comprise from a groove.
As a result, the storage box storing the compression cylinder can be stably held on the column, and the storage box can be easily moved to the avoidance position and the use position by moving along the rail, and has a simple structure. Can be realized.

　以下において本発明にかかるＸ線透視撮影台について図面に示した実施例に基づき説明する。
　図１は本発明にかかるＸ線透視撮影台の概略構成を示した全体図であって、床面に設置固定される基台１と、この基台１に立てられた支柱２と、前記支柱２の前面で基台１に起倒可能に支持された天板３と、この天板３上の被検者を透視撮影するために支柱２の上端に設けられたＸ線管４と、該Ｘ線管４に相対して天板３の下方に配置されたＸ線像検出部５と、Ｘ線管４と天板３との間で前記支柱２に取り付けられて、圧迫筒７を取り出し可能に格納する格納箱８とからなる。圧迫筒７は回動並びに伸縮可能なアーム９を介して図１の仮想線に示すように下方に反転して被検者の撮影部位を圧迫することができるように形成されており、この圧迫筒７を、格納位置から被検者の撮影部位を圧迫する使用姿勢まで反転作動させるためのモータを含む駆動機構が格納箱８内に内蔵されている。なお、この圧迫筒７の駆動機構は、例えば特許文献１や特許文献２でも開示されているようによく知られているため、その詳細な説明は省略する。 Hereinafter, an X-ray fluoroscopic imaging table according to the present invention will be described based on an embodiment shown in the drawings.
FIG. 1 is an overall view showing a schematic configuration of an X-ray fluoroscopic imaging table according to the present invention, a base 1 installed and fixed on a floor surface, a support 2 standing on the base 1, and the support A top plate 3 supported by the base 1 on the front surface of the base plate 2 so as to be able to rise and fall, an X-ray tube 4 provided at the upper end of the column 2 for fluoroscopic imaging of the subject on the top plate 3, The X-ray image detection unit 5 disposed below the top plate 3 relative to the X-ray tube 4 is attached to the support column 2 between the X-ray tube 4 and the top plate 3, and the compression cylinder 7 is taken out. It consists of a storage box 8 that stores it as possible. The compression cylinder 7 is formed so as to be able to press down the imaging region of the subject by being turned downward as shown by an imaginary line in FIG. A drive mechanism including a motor for reversing the cylinder 7 from the storage position to a use posture for pressing the imaging region of the subject is incorporated in the storage box 8. The driving mechanism of the compression cylinder 7 is well known as disclosed in, for example, Patent Document 1 and Patent Document 2, and therefore detailed description thereof is omitted.
　更に前記圧迫筒７の格納箱８が、支柱２の前面に位置する使用位置から支柱側面に位置する回避位置まで格納箱回避機構１０を介して移動可能に形成されている。 Further, the storage box 8 of the compression cylinder 7 is formed to be movable through the storage box avoiding mechanism 10 from the use position located on the front surface of the support column 2 to the avoidance position positioned on the side surface of the support column.
　図２～図３は上記格納箱回避機構１０の第１実施例を示すものであって、この実施例では支柱８の前面縁部に軸１１を介して回動可能に取り付けられた蝶番部材１２に格納箱８が取り付けられ、この軸１１を支点として格納箱８を回動することにより、図２の支柱前面に配置される使用位置から、図３の支柱側面に配置される回避位置まで移動できるように形成されている。
　また、格納箱８が使用位置にある時にその姿勢を安定よく保持するための保持機構が講じられている。本実施例にあっては、格納箱８の背面と支柱２との間にマグネットキャッチ１３並びに鉄板１４が設けられており、同様に、回避位置で格納箱８の姿勢を仮保持するマグネットキャッチ１５並びに鉄板１６が設けられている。尚、格納箱８の姿勢を保持する手段はマグネットキャッチに限るものでなく、その他の手段、例えば弾性的に係合するラッチ等であってもよく、あるいは着脱可能なフックやビス等で確実に止着するようにしてもよい。 FIGS. 2 to 3 show a first embodiment of the containment box avoiding mechanism 10. In this embodiment, a hinge member 12 rotatably attached to the front edge of the support column 8 via a shaft 11. The storage box 8 is attached to the shaft, and the storage box 8 is rotated about the shaft 11 as a fulcrum, so that the storage box 8 is moved from the use position disposed on the front surface of the support column in FIG. It is formed to be able to.
Further, a holding mechanism is provided for stably holding the posture of the storage box 8 when it is in the use position. In the present embodiment, the magnet catch 13 and the iron plate 14 are provided between the back surface of the storage box 8 and the support column 2, and similarly, the magnet catch 15 that temporarily holds the attitude of the storage box 8 at the avoidance position. In addition, an iron plate 16 is provided. The means for holding the attitude of the storage box 8 is not limited to the magnet catch, but may be other means such as an elastically engaged latch or the like, or securely with a detachable hook or screw. You may make it fix.
　従ってこの実施例にあっては、格納箱８を蝶番部材の軸１１を支点として回動させることにより圧迫筒７を使用位置から回避位置まで、或いは回避位置から使用位置まで移動させることができる。 Therefore, in this embodiment, the compression cylinder 7 can be moved from the use position to the avoidance position or from the avoidance position to the use position by rotating the storage box 8 with the shaft 11 of the hinge member as a fulcrum.
　図４～図６は蝶番部材を利用した格納箱回避機構１０の第２の実施例を示すものであって、この実施例では支柱２の側面に前後方向に沿ってレール１７が設けられ、このレールに沿ってスライド部材１８が摺動できるように形成されている。このスライド部材１８に軸１９を支点として回動する蝶番部材２０が取り付けられている。圧迫筒７を格納する格納箱８は、図４に示すように蝶番部材２０が支柱２の前面に接する姿勢まで回動したときに使用位置となるように蝶番部材２０に取り付けられている。そして図４の使用位置から図５に示すように蝶番部材１７を９０度回転させたあと、スライド部材１８を介して格納箱８をレール１７に沿って押し込んで移動させることにより図５の回避位置まで移動できるように形成されている。この場合も先の実施例と同様に、格納箱８の使用位置と回避位置とでその姿勢を安定保持するキャッチ等の保持機構を設けるのがよい。 4 to 6 show a second embodiment of the storage box avoiding mechanism 10 using a hinge member. In this embodiment, a rail 17 is provided along the front-rear direction on the side surface of the support column 2. The slide member 18 is formed to be slidable along the rail. A hinge member 20 that rotates about a shaft 19 is attached to the slide member 18. The storage box 8 for storing the compression cylinder 7 is attached to the hinge member 20 so as to be in a use position when the hinge member 20 is rotated to a posture in contact with the front surface of the column 2 as shown in FIG. Then, after the hinge member 17 is rotated 90 degrees from the use position of FIG. 4 as shown in FIG. 5, the storage box 8 is pushed along the rail 17 through the slide member 18 and moved, thereby avoiding the avoidance position of FIG. It can be moved up to. In this case as well, as in the previous embodiment, it is preferable to provide a holding mechanism such as a catch that stably holds the posture of the storage box 8 at the use position and the avoidance position.
　図７～図９は本発明における格納箱回避機構１０の第３の実施例を示す。この実施例では、支柱２が円柱状をなし、この円柱状支柱２の周囲に設けられた円弧状のレール２１が設けられ、該レール２１に、格納箱８の背面に形成された嵌合溝２２が摺動できるように取り付けられている。この嵌合溝２２は、図９に示すように格納箱８がレール２１から脱落しないようにアリ溝の形態で形成されている。

And it is realizable with a simple structure. Further, as shown in FIG. 10, the storage box 8 can be avoided on either side of the column 2 by extending the arc-shaped rail 21 to the left and right sides of the column 2.
In this embodiment as well, as in the first and second embodiments, it is of course preferable to provide a holding mechanism such as a catch that stably holds the posture of the storage box 8 at the use position and the avoidance position. .
　また、上記第３実施例において、支柱２を円柱状としたが、図１１に示すように一般的な四角柱の支柱２に対しても、その周囲に円弧状のレール２１を配設することにより、第３実施例と同様な格納箱回避機構１０を形成することができる。 Further, in the third embodiment, the column 2 is cylindrical. However, as shown in FIG. 11, an arc-shaped rail 21 is disposed around the column 2 as a general square column. Thus, the storage box avoidance mechanism 10 similar to that of the third embodiment can be formed.
　以上本発明の代表的な実施例について説明したが、本発明は必ずしも上記の実施例構造のみに特定されるものではない。例えば、格納箱回避機構１０は使用位置と回避位置とに移動できる機構であればどのようなものであってもよい。その他本発明ではその目的を達成し、請求の範囲を逸脱しない範囲内で適宜修正、変更することが可能である。 The representative embodiments of the present invention have been described above, but the present invention is not necessarily limited to the above-described embodiment structures. For example, the storage box avoidance mechanism 10 may be any mechanism that can move between the use position and the avoidance position. In addition, the present invention achieves its object and can be appropriately modified and changed without departing from the scope of the claims.
