Description

本発明は、被検者を載置する検診台と載置された被検者の患部を撮影するＸ線透視撮影装置などの医用機器を安全に操作することができる医用診断装置に関する。   The present invention relates to a medical diagnostic apparatus capable of safely operating medical equipment such as an examination table on which a subject is placed and an X-ray fluoroscopic imaging apparatus that photographs an affected area of the placed subject.

医用診断装置は図９に示すとおり検診台７に横臥させた被検者６の患部を撮影するＸ線透視撮影装置ＸＤが広く用いられている。このＸ線透視撮影装置ＸＤは、被検者６の関心領域を様々な角度から透視・撮影できるよう、多軸駆動されるＣアーム４にＸ線管球２とＸ線受像装置３を備えた構造をしている。図９において８は基台であり、９Ａは操作部、１０は操作部ＢＯＸ、１１は滅菌用オイフ、１２はジョイスティック型操作器である。このＣアーム４の操作は、例えば血管造影の検査の場合、カテーテル操作は術者または専門技師が行なうが、Ｃアーム４の操作は遠隔操作で行なわれ、そのための操作部９Ａは、図９に示すとおり被検者６が横臥する検診台７近傍に設置されることが多いが、検診台７から離されて設置される場合や検査室の外に設置される場合もある。   As a medical diagnostic apparatus, as shown in FIG. 9, an X-ray fluoroscopic apparatus XD that captures an affected area of a subject 6 lying on an examination table 7 is widely used. This X-ray fluoroscopic apparatus XD includes the X-ray tube 2 and the X-ray image receiving apparatus 3 on a multi-axis driven C-arm 4 so that the region of interest of the subject 6 can be viewed and imaged from various angles. Has a structure. In FIG. 9, 8 is a base, 9A is an operation unit, 10 is an operation unit BOX, 11 is a sterilization owl, and 12 is a joystick type operation device. For example, in the case of angiographic examination, the C-arm 4 is operated by an operator or an expert engineer. The C-arm 4 is operated by remote control, and the operation unit 9A for the operation is shown in FIG. As shown in the figure, it is often installed in the vicinity of the examination table 7 on which the subject 6 is lying, but may be installed away from the examination table 7 or may be installed outside the examination room.

Ｃアーム４は図９に示すように水平方向Ｈでの軸芯方向ＡＸおよびラジアル方向ＲＺ、Ｃアーム軸方向Ｃ、基台Ｄ上の架台Ｕの水平方向Ｈおよび支軸回転方向ＲＯなどの多軸で複雑な動きをするため、操作部９Ａはできるだけ簡略にする必要があり、ジョイスティック型操作器１２を使用する場合が多い。   As shown in FIG. 9, the C arm 4 includes a horizontal axis H in the axial direction AX and a radial direction RZ, a C arm axis direction C, a horizontal direction H of the gantry U on the base D, and a spindle rotation direction RO. In order to make a complicated movement on the shaft, the operation unit 9A needs to be as simple as possible, and the joystick type operation device 12 is often used.

図１０は前記操作部９Ａの上面図（Ａ）と側面図（Ｂ）である。この操作部９Ａは例えば前記Ｃアーム４（図９）を水平方向Ｈでの軸芯方向ＡＸとラジアル方向ＲＺの移動操作を行なうジョイスティック型操作器１２Ａと、Ｃアーム４の軸方向Ｃおよび支軸の回転方向ＲＯの移動操作を行なうジョイスティック型操作器１２Ｂと、透視線量レベルを選択する操作スイッチ１２Ｃ、Ｘ線受像装置３の視野範囲を選択する操作スイッチ１２Ｄなどの各操作器が並設されている。この操作部９Ａは、操作部ＢＯＸ１０の側方に固定される。この医用診断装置で検診を行なう場合、被検者６への雑菌の侵入を防ぐために通常検診台７上の被検者６の上面に滅菌用オイフ１１が掛けられる。   FIG. 10 is a top view (A) and a side view (B) of the operation unit 9A. The operation unit 9A includes, for example, a joystick type operating device 12A for moving the C arm 4 (FIG. 9) in the horizontal axis H in the axial direction AX and the radial direction RZ, and the axial direction C and the support shaft of the C arm 4. Are arranged in parallel, such as a joystick-type operation device 12B for performing a moving operation in the rotational direction RO, an operation switch 12C for selecting a fluoroscopy dose level, and an operation switch 12D for selecting a visual field range of the X-ray image receiving apparatus 3. Yes. The operation unit 9A is fixed to the side of the operation unit BOX10. When a medical examination is performed with this medical diagnostic apparatus, a sterilization arm 11 is placed on the upper surface of the subject 6 on the normal examination table 7 in order to prevent invasion of germs into the subject 6.

前記ジョイスティック型操作器１２Ａおよび１２Ｂでは、操作レバー１２Ｒに不用意に操作者や被検者の体が触れ、または当接してジョイスティック型操作器１２Ａまたは１２Ｂが不用意に危険な作動を行なうのを停止させるため操作レバー１２Ｒの上面に確認用のスイッチを設け、操作時はこのスイッチを押し込み停止状態を解除してから操作レバー１２Ｒを傾動させるようにして誤操作を防いでいる（例えば、特許文献１参照）。
特開平０８−２９９３９３号公報 In the joystick-type operating devices 12A and 12B, the operator or the subject's body inadvertently touches or comes into contact with the operating lever 12R, and the joystick-type operating device 12A or 12B performs an inadvertently dangerous operation. In order to stop, a confirmation switch is provided on the upper surface of the operation lever 12R. During operation, the switch is pushed in to release the stop state, and then the operation lever 12R is tilted to prevent erroneous operation (for example, Patent Document 1). reference).
Japanese Patent Laid-Open No. 08-299393

しかしながら、実際の検査では、被検者の上に被せる滅菌用オイフを検診台横の操作部の上にまで被せて使用するので、スイッチがレバー上面にある場合は滅菌用オイフによってスイッチが押される場合があり、また滅菌用オイフが引っ張られたりして動いた際に不意にＸ線管球やＸ線受像装置が移動する。他方、操作時には簡単にスイッチが入る構造でなければならない。   However, in the actual examination, the sterilization arm to be placed on the subject is put on the operation unit beside the examination table, so that the switch is pushed by the sterilization off if the switch is on the upper surface of the lever. In some cases, the X-ray tube and the X-ray image receiving device move unexpectedly when the sterilizing arm is pulled and moved. On the other hand, the structure must be easily switched on during operation.

In order to solve the above problems, the medical diagnostic apparatus of the present invention is a medical diagnostic apparatus having an operation lever for giving an operation instruction to a medical diagnostic device. The operation lever includes an operation lever shaft and the operation lever. A cylindrical handle having an inner hole into which the lever shaft is inserted and slidable in the axial direction of the operation lever shaft from the upper end with respect to the operation lever shaft, a switch that is turned on at the time of the slide, receiving an on signal and a control unit to be valid instruction for operating the medical diagnostic apparatus according to the operating lever, the slidable tubular handle is you are assumed not to protrude with respect to the operating lever shaft.

さらに前記筒状の把手は、操作レバー軸のフランジ部に一端が係止されたコイルばねの他端を係止するフランジ部が内設され、前記把手はスライドに対して復元される方向に付勢されているものである。   Further, the cylindrical handle is provided with a flange portion for locking the other end of the coil spring whose one end is locked to the flange portion of the operation lever shaft, and the handle is attached in a direction to be restored to the slide. It is what is being energized.

Ｘ線透視撮影装置を操作する際、操作者は透視画像をモニターで画像と被検者の状態を確認しながら行なうので、操作レバーを見ないで操作する場合が多い。このため従来の小形の押ボタン型の確認スイッチではその位置を確認し難いが、本発明による操作レバーでは確認スイッチの捜索が不要となる。また、操作部に滅菌用オイフなどを被せた状態で操作レバーを操作する場合は、さらに小さい押ボタンは操作が一層操作し難いが、本発明の操作レバーによる確認スイッチの作動機構はより有益である。   When operating the X-ray fluoroscopic apparatus, the operator often performs the operation without looking at the operation lever because the operator performs the fluoroscopic image while checking the image and the state of the subject on the monitor. For this reason, it is difficult to confirm the position with the conventional small push button type confirmation switch, but the operation lever according to the present invention does not require searching for the confirmation switch. In addition, when operating the operation lever with the operation part covered with a sterilization arm or the like, the operation of the confirmation switch using the operation lever of the present invention is more useful, although the operation of the smaller push button is more difficult to operate. is there.

本発明の実施例による医用診断装置を図面を参照しながら説明する。なお、図９の医用診断装置と同一の構成部品には同一符号を付して示す。図１は本発明による医用診断装置の構成図である。本医用診断装置はＸ線管と駆動電源部からなりＸ線を発生するＸ線管球２を下端に、その透過Ｘ線を検出して画像に変換するＸ線受像装置３を上端に取り付けたＣアーム４をＣアーム軸方向Ｃ、回転方向ＲＨおよび上下方向ＨＺに移動可能な保持装置５を備えたＸ線透視撮影装置１と、被検者６を載置する検診台７を載設し、この検診台７を上下および水平方向に移動させる駆動機構を備えた基台８と、前記Ｘ線透視撮影装置１をその撮影条件に合わせるために操作するジョイスティック型操作器１３や操作スイッチ３１を集めた操作部９等の医用機器と、前記操作部９を横設し操作部９からの操作信号を受信して演算処理を行ない、撮影条件に合わせた制御信号を出力する制御機能を備えた操作部ＢＯＸ１０等から構成されている。   A medical diagnostic apparatus according to an embodiment of the present invention will be described with reference to the drawings. The same components as those in the medical diagnostic apparatus in FIG. 9 are denoted by the same reference numerals. FIG. 1 is a block diagram of a medical diagnostic apparatus according to the present invention. This medical diagnostic apparatus includes an X-ray tube and a drive power supply unit, and an X-ray tube 2 that generates X-rays is attached to the lower end, and an X-ray image receiving device 3 that detects the transmitted X-ray and converts it to an image is attached to the upper end. An X-ray fluoroscopic apparatus 1 having a holding device 5 capable of moving the C-arm 4 in the C-arm axial direction C, the rotational direction RH, and the up-down direction HZ, and an examination table 7 on which the subject 6 is placed are placed. A base 8 having a drive mechanism for moving the examination table 7 in the vertical and horizontal directions, and a joystick type operating device 13 and an operation switch 31 for operating the X-ray fluoroscopic apparatus 1 to meet the imaging conditions are provided. The collected medical devices such as the operation unit 9 and a control function for horizontally operating the operation unit 9 to receive an operation signal from the operation unit 9 to perform arithmetic processing and to output a control signal in accordance with imaging conditions It is composed of an operation unit BOX 10 and the like.

実施例によるジョイスティック型操作器１３の構成を図２の縦断断面図（Ａ）およびＡ−Ａ断面図（Ｂ）に、操作レバー軸１５の斜視図を図３に示す。本ジョイスティック型操作器１３は、前記操作部９内のジョイスティック支持台２９に支持され左右前後に傾動できる操作レバー１３Ａと当該操作レバー１３Ａの傾動操作により前記保持装置５を操作する操作信号を送信する制御部３０から構成される。なお、図３はマイクロスイッチ１４が収容部位１５ｋに収容されている状態を斜視的に示す図で、図示例では操作レバー軸１５がコ字形に切欠されて収容部位１５ｋが形成されている。   The configuration of the joystick type operating device 13 according to the embodiment is shown in the longitudinal sectional view (A) and AA sectional view (B) in FIG. 2, and the perspective view of the operating lever shaft 15 is shown in FIG. The joystick-type operating device 13 is supported by a joystick support base 29 in the operation unit 9 and transmits an operation lever 13A that can be tilted to the left and right and back and an operation signal for operating the holding device 5 by the tilting operation of the operation lever 13A. The control unit 30 is configured. FIG. 3 is a perspective view showing a state in which the microswitch 14 is housed in the housing portion 15k. In the illustrated example, the operating lever shaft 15 is cut into a U-shape to form the housing portion 15k.

前記操作レバー１３Ａは、作動片１４ａを有するマイクロスイッチ１４と、作動片１４ａの先端を下向きにしてマイクロスイッチ１４をネジ１４ｂで螺着するための収容部位１５ｋとコイルばね１６の一端を係止させるフランジ部１５ｂを形成した操作レバー軸１５と、前記作動片１４ａを収容する凹部１７ａ、押し下げられることにより作動片１４ａに当接する傾斜面１７ｂ、前記コイルばね１６の他端を係止させるフランジ部１７ｃ、抜止用のフランジ部１７ｄおよび前記操作レバー軸１５が嵌合する貫通孔１７ｅが形成された把手１７から構成されている。前記マイクロスイッチ１４の接点信号は操作レバー軸１５の内部を通る信号ケーブル１８を介して前記操作部９内の制御部３０に送信される。   The operating lever 13A engages one end of a coil spring 16 with a microswitch 14 having an operating piece 14a, a receiving portion 15k for screwing the microswitch 14 with a screw 14b with the tip of the operating piece 14a facing downward. An operating lever shaft 15 formed with a flange portion 15b, a concave portion 17a that accommodates the operating piece 14a, an inclined surface 17b that contacts the operating piece 14a when pressed down, and a flange portion 17c that engages the other end of the coil spring 16. , A flange 17d for retaining and a handle 17 in which a through hole 17e into which the operation lever shaft 15 is fitted is formed. The contact signal of the micro switch 14 is transmitted to the control unit 30 in the operation unit 9 via a signal cable 18 passing through the inside of the operation lever shaft 15.

マイクロスイッチ１４からの接点ＯＮ信号が前記制御部３０の制御用基板２７に入力されると、制御用基板２７からは左右に配置される操作指示発信器２８ａ、２８ｂおよび前後に配置される操作指示発信器２８ｃ、２８ｄ（図示せず）に送信許可信号が送られ、操作レバー軸１５の傾動により操作指示発信器２８ａ〜２８ｄは前記保持装置５を操作する操作信号を送信する機能に切り換えられ、前記操作部ＢＯＸ１０を介して保持装置５に制御信号が送信される。   When the contact ON signal from the micro switch 14 is input to the control board 27 of the control unit 30, the operation instruction transmitters 28a and 28b arranged on the left and right and the operation instructions arranged on the front and rear sides from the control board 27. Transmission permission signals are sent to the transmitters 28 c and 28 d (not shown), and the operation instruction transmitters 28 a to 28 d are switched to a function of transmitting an operation signal for operating the holding device 5 by tilting the operation lever shaft 15. A control signal is transmitted to the holding device 5 via the operation unit BOX 10.

すなわちマイクロスイッチ１４からの接点ＯＮ信号が制御用基板２７に入力されないかぎり各操作指示発信器２８ａ〜２８ｄは制御信号を発生しないように構成されている。制御部３０は上記のとおり制御機能を発揮する。操作レバー軸１５はＸ方向、Ｙ方向に傾動自在で傾動によりその下端部が操作指示発信器２８ａ〜２８ｄのいずれかを押すことになる。   That is, unless the contact ON signal from the micro switch 14 is input to the control board 27, each of the operation instruction transmitters 28a to 28d is configured not to generate a control signal. The control unit 30 performs the control function as described above. The operation lever shaft 15 is tiltable in the X direction and the Y direction, and the lower end of the operation lever shaft presses one of the operation instruction transmitters 28a to 28d.

図４は前記操作レバー１３Ａの動作を説明する縦断断面図、図５は操作部９のジョイスティック型操作器１３により、Ｃアーム４を軸方向Ｃに移動または水平方向ＲＨに回転させる場合の動作手順を示すフローチャートである。前記Ｃアーム４を移動させる場合は、操作レバー１３Ａの把手１７を把持して図４に示すように点線位置から下方にスライドさせる（ＳＴ１）。するとマイクロスイッチ１４の作動片１４ａが傾斜面１７ｂに係合してマイクロスイッチ１４の接点がＯＮになり、このＯＮ信号が制御用基板２７に送信される（ＳＴ２）。そして制御用基板２７から操作指示発信器２８ａ〜２８ｄに送信許可信号が送信され、操作指示発信器２８ａ〜２８ｄから前記操作部ＢＯＸ１０を介して保持装置５を遠隔操作するための操作信号が送信できる状態にセットされる（ＳＴ３）。この状態で操作レバー１３Ａを左右または前後方向に傾動させると（ＳＴ４）、その傾動方向に対応する操作指示発信器２８ａ〜２８ｄのいずれかから操作信号が出力され、この操作信号は操作部ＢＯＸ１０を介して保持装置５に送信される（ＳＴ５）。Ｃアーム４は操作信号に基づき制御され軸方向Ｃまたは回転方向ＲＨに沿って移動する（ＳＴ６）。操作レバー１３Ａの傾動方向を変えながらＣアーム４を最適位置に調節する（ＳＴ４〜ＳＴ６）。   FIG. 4 is a longitudinal sectional view for explaining the operation of the operation lever 13A. FIG. 5 is an operation procedure when the C arm 4 is moved in the axial direction C or rotated in the horizontal direction RH by the joystick type operation device 13 of the operation unit 9. It is a flowchart which shows. When moving the C-arm 4, the handle 17 of the operating lever 13A is grasped and slid downward from the dotted line position as shown in FIG. 4 (ST1). Then, the operating piece 14a of the micro switch 14 is engaged with the inclined surface 17b, the contact of the micro switch 14 is turned ON, and this ON signal is transmitted to the control board 27 (ST2). A transmission permission signal is transmitted from the control board 27 to the operation instruction transmitters 28a to 28d, and an operation signal for remotely operating the holding device 5 can be transmitted from the operation instruction transmitters 28a to 28d via the operation unit BOX10. The state is set (ST3). In this state, when the operation lever 13A is tilted left or right or in the front-rear direction (ST4), an operation signal is output from any of the operation instruction transmitters 28a to 28d corresponding to the tilt direction, and the operation signal is sent to the operation unit BOX10. To the holding device 5 (ST5). The C arm 4 is controlled based on the operation signal and moves along the axial direction C or the rotational direction RH (ST6). The C arm 4 is adjusted to the optimum position while changing the tilt direction of the operation lever 13A (ST4 to ST6).

前記操作レバー１３Ａの変形例を図６に示す。この操作レバー１９は前記操作レバー軸１５の先端に円形部材２０を嵌着するとともに、前記把手１７の代わりに先端部に傾斜面１７ｆを形成した把手１７Ａを用いたものである。これにより、把手１７Ａを握り点線位置から下方に移動させた時、握り手の親指と人指し指部分が前記円形部材２０と傾斜面１７ｆの凹み部分に入り込み前記コイルばね１６による把手１７Ａの押し上げが前記円形部材２０で阻止されるので操作が容易になる。   A modification of the operation lever 13A is shown in FIG. The operating lever 19 uses a handle 17A in which a circular member 20 is fitted to the tip of the operating lever shaft 15 and an inclined surface 17f is formed at the tip instead of the handle 17. Thereby, when the grip 17A is moved downward from the position of the dotted line, the thumb and index finger portion of the grip enters the concave portion of the circular member 20 and the inclined surface 17f, and the push-up of the grip 17A by the coil spring 16 is the circular shape. Since it is blocked by the member 20, the operation becomes easy.

図７はスイッチとして磁気センサーを用いた場合の操作レバー２１の縦断断面図である。この操作レバー２１は、前記収容部位１５ｋの代わりに磁気センサー２２を固設する収容部位１５ｃを形成した操作レバー軸１５Ａと磁石２３を嵌合させた把手１７Ｂを有しており、把手１７Ｂが下がると磁気センサー２２は磁石２３の磁場の強さを検出しこの検出信号が前記制御部３０に送信される。   FIG. 7 is a longitudinal sectional view of the operation lever 21 when a magnetic sensor is used as a switch. The operation lever 21 has a handle 17B in which a magnet 23 is fitted to an operation lever shaft 15A in which an accommodation portion 15c for fixing the magnetic sensor 22 is fixed instead of the accommodation portion 15k, and the handle 17B is lowered. The magnetic sensor 22 detects the strength of the magnetic field of the magnet 23, and this detection signal is transmitted to the control unit 30.

図８はスイッチとして発光素子と受光素子を間隙１５ｄを設けて一体的にモールド化したホトカプラー２４を用いた場合の操作レバー２５の縦断断面図（Ａ）、Ｂ−Ｂ断面図（Ｂ）および上面図（Ｃ）である。本操作レバー２５は、ホトカプラー２４を収容部位１５ｅに固設した操作レバー軸１５Ｂと前記ホトカプラー２４の光路を遮蔽する光遮蔽片２６を固定した把手１７Ｃから構成される。   FIG. 8 is a longitudinal sectional view (A), BB sectional view (B) and top view of the operating lever 25 when a photocoupler 24 in which a light emitting element and a light receiving element are integrally molded with a gap 15d as a switch is used. It is a figure (C). The operation lever 25 includes an operation lever shaft 15B in which the photocoupler 24 is fixed to the accommodating portion 15e, and a handle 17C to which a light shielding piece 26 for shielding the optical path of the photocoupler 24 is fixed.

前記操作レバー軸１５Ｂは把手１７Ｃが上下する範囲域で縦方向に前記間隙１５ｄと連結する割溝１５ｆが形成され、この割溝１５ｆに対して前記把手１７Ｃに固定された光遮蔽片２６が挿入されていて上下動する。この光遮蔽片２６の上下動域に前記ホトカプラー２４が固設されている。把手１７Ｃを下げるとホトカプラー２４の光路が遮断され、その検出信号が前記制御部３０に送信される。   The operating lever shaft 15B is formed with a split groove 15f that is connected to the gap 15d in the vertical direction in a range where the handle 17C moves up and down, and a light shielding piece 26 fixed to the handle 17C is inserted into the split groove 15f. It moves up and down. The photocoupler 24 is fixed in the vertical movement region of the light shielding piece 26. When the handle 17C is lowered, the optical path of the photocoupler 24 is blocked, and the detection signal is transmitted to the control unit 30.

なお、図２のジョイスティック型操作器１３はあくまで作動原理図を示すもので、図示構造に限定されるものではない。また前記操作部９に用いるジョイスティック型操作器１３や操作スイッチ３１の個数は図１に示すものに限定されるものではなく、操作部９は、検診台７以外の滅菌用オイフ１１を使用する医用機器にも用いられる。   Note that the joystick type operating device 13 in FIG. 2 is merely an operation principle diagram, and is not limited to the illustrated structure. Further, the number of joystick type operating devices 13 and operation switches 31 used in the operation unit 9 is not limited to that shown in FIG. 1, and the operation unit 9 is a medical device that uses a sterilization office 11 other than the examination table 7. Also used in equipment.
