医療用プロジェクター１８の側面部には下端周囲に７つの照明２７が異なる長さの支持バー２８により医療用プロジェクター１８から離れた状態で且つ円周状に並んだ状態で配置されている。
On the side surface of the medical projector 18, seven illuminations 27 are arranged around the lower end in a state of being separated from the medical projector 18 by a support bar 28 having a different length and arranged in a circumferential shape.
スタンド装置１によりドクターＤの頭部より高い位置に支持された医療用プロジェクター１８は患者Ｐの手術中の臓器Ｇから蛍光部分を撮影して、それを可視画像化してリアルタイムで臓器Ｇに投影するための装置である。医療用プロジェクター１８の下面２１には窓２９が形成され、その四方にはそれぞれ特定波長の励起光Ｅを発する励起光照明３０が設けられている。窓２９の周囲に励起光照明３０があるため、励起光Ｅを臓器Ｇに対してあらゆる方向から照射することができる。
The medical projector 18 supported by the stand device 1 at a position higher than the head of the doctor D takes a fluorescent part from the organ G during the operation of the patient P, visualizes it, and projects it onto the organ G in real time. It is a device for. Windows 29 are formed on the lower surface 21 of the medical projector 18, and excitation light illuminations 30 that emit excitation light E having a specific wavelength are provided on each of the windows 29. Since there is the excitation light illumination 30 around the window 29, the excitation light E can be applied to the organ G from all directions.
医療用プロジェクター１８の内部には窓２９の真上に光を部分的に透過・反射する光分岐手段３１が設けられている。更に内部にはプロジェクター部３２とカメラ部３３が設けられている。カメラ部３３の内部には蛍光カメラ３４と可視光カメラ３５が設けられており、蛍光と可視光に分離する図示せぬ光学フィルタ手段も設けられている。
In the inside of the medical projector 18, there is provided a light branching means 31 that partially transmits and reflects light directly above the window 29. Further, a projector unit 32 and a camera unit 33 are provided inside. A fluorescence camera 34 and a visible light camera 35 are provided inside the camera unit 33, and optical filter means (not shown) for separating the fluorescence and visible light is also provided.
患者Ｐには予め人体に安全な蛍光試薬が投与される。手術室内の無影灯３６は基本的に消灯する。励起光照明３０から特定波長の励起光Ｅを手術部位の臓器Ｇに照射する。すると臓器Ｇを含む術野において、肉眼では見えない組織表面下の血管やリンパ管の流れ或いは腫瘍等が蛍光発光部Ｆとして発光する。その蛍光発光部Ｆからの蛍光を含む術野からの反射光Ａを窓２９から医療用プロジェクター１８の内部に取入れてカメラ部３３に導く。カメラ部３３では反射光Ａを蛍光と可視光に分離し、蛍光は蛍光カメラ３４で、可視光は可視光カメラ３５で撮影する。
The patient P is preliminarily administered with a fluorescent reagent safe for the human body. The operating light 36 in the operating room is basically turned off. The excitation light illumination 30 irradiates the organ G at the surgical site with the excitation light E having a specific wavelength. Then, in the operative field including the organ G, a blood flow or a lymph vessel flow or a tumor under the surface of the tissue that cannot be seen with the naked eye emits light as the fluorescent light emitting portion F. The reflected light A from the surgical field including the fluorescence from the fluorescent light emitting unit F is taken into the medical projector 18 through the window 29 and guided to the camera unit 33. The camera unit 33 separates the reflected light A into fluorescence and visible light, and the fluorescence is captured by the fluorescence camera 34 and the visible light is captured by the visible light camera 35.
蛍光カメラ３４で撮影された蛍光画像Ｂは可視画像化されてプロジェクター部３２へ送られ、プロジェクター部３２から光分岐手段３１を介して窓２９より臓器Ｇに投影される。蛍光画像Ｂが臓器Ｇにリアルタイムで投影されるプロジェクションマッピングとなる。リアルタイムの投影のため、臓器Ｇの変形や移動にも時差なく追従し、ドクターＤはその臓器Ｇに投影された蛍光画像Ｂを参考にして手術を行うことができる。
The fluorescent image B captured by the fluorescent camera 34 is visualized and sent to the projector unit 32, and is projected from the projector unit 32 to the organ G through the light branching means 31 through the window 29. This is projection mapping in which the fluorescent image B is projected onto the organ G in real time. Due to the real-time projection, the deformation and movement of the organ G can be followed without any time difference, and the doctor D can perform an operation with reference to the fluorescent image B projected onto the organ G.
ドクターＤが投影された蛍光画像Ｂを確認した後に手術を開始すると、図４に示すように、投影された蛍光画像ＢがドクターＤの手２２に遮られて臓器Ｇに当たらない場合がある。その場合臓器Ｇが手２２の陰になるが、照明２７が窓２９の全周を取り囲む状態で設けられており、照明２７の白色光Ｈを臓器Ｇに対して全方向から照射しているため、いずれかの照明２７は臓器Ｇを明るく照らすことができる。
When surgery is started after the doctor D has confirmed the projected fluorescent image B, the projected fluorescent image B may be blocked by the hand 22 of the doctor D and not hit the organ G as shown in FIG. In that case, the organ G is behind the hand 22, but the illumination 27 is provided in a state surrounding the entire circumference of the window 29, and the white light H of the illumination 27 is irradiated to the organ G from all directions. Any one of the illuminations 27 can illuminate the organ G brightly.
しかも、照明２７が下面２１によりも外側へ突出した状態で支持されているため、臓器Ｇに対する照明２７の白色光Ｈは入射角度θが小さくなり、ドクターＤの手２２の下側に入り込んでより確実に臓器Ｇを照らすことができる。手術中は時々臓器Ｇから手２２を離し、再度臓器Ｇに蛍光画像Ｂを投影して確認しながら手術を進められる。
In addition, since the illumination 27 is supported in a state of protruding outward from the lower surface 21, the white light H of the illumination 27 with respect to the organ G has a smaller incident angle θ, and enters the lower side of the hand 22 of the doctor D. The organ G can be surely illuminated. During the operation, the hand 22 is occasionally released from the organ G, and the operation can be performed while projecting and confirming the fluorescent image B on the organ G again.
手術中に医療用プロジェクター１８の投影方向を変更する場合は、操作ハンドル２６を握りながら操作することにより、スタンド装置１の回転部分の電磁クラッチをフリーにして、医療用プロジェクター１８を全体的に上下或いは前後左右に移動させることができる。そして医療用プロジェクター１８が、第１回転軸Ｘを中心に保持アーム９ごと回転し、第２回転軸Ｙを中心にリング状ベアリング１３ごと回転し、リング状ベアリング１３の中心軸Ｚを中心に回転するため、投影方向を任意に変更することができる。
When changing the projection direction of the medical projector 18 during the operation, the electromagnetic clutch of the rotating part of the stand device 1 is released by operating while holding the operation handle 26, and the medical projector 18 is moved up and down as a whole. Alternatively, it can be moved back and forth and left and right. The medical projector 18 rotates with the holding arm 9 about the first rotation axis X, rotates with the ring-shaped bearing 13 about the second rotation axis Y, and rotates about the central axis Z of the ring-shaped bearing 13 Therefore, the projection direction can be arbitrarily changed.
本発明の第１の技術的側面によれば、医療用プロジェクターの窓の全周を取り囲む状態で複数の照明が設けられているため、照明の光を術野に対して全方向から照射することができ、投影画像がドクターの手により遮られても、いずれかの照明は術野を明るく照らすことができる。
According to the first technical aspect of the present invention, since a plurality of illuminations are provided so as to surround the entire circumference of the window of the medical projector, the illumination light is emitted from all directions to the surgical field. Even if the projected image is obstructed by the doctor's hand, either illumination can illuminate the surgical field brightly.
本発明の第２の技術的側面によれば、照明が下面よりも外側へ突出した状態で支持されているため、術野に対する照明の光の入射角度が小さくなり、ドクターの手の下側に入り込んで術野をより確実に照らすことができる。
According to the second technical aspect of the present invention, since the illumination is supported in a state of protruding outward from the lower surface, the incident angle of the illumination light with respect to the operative field is reduced, and the lower side of the doctor's hand. It is possible to enter and illuminate the surgical field more reliably.
本発明の第３の技術的側面によれば、励起光照明が下面における窓の周囲に設けられているため、励起光も術野に対して全方向から照射することができる。
According to the third technical aspect of the present invention, since the excitation light illumination is provided around the window on the lower surface, the excitation light can be applied to the surgical field from all directions.
