Description

医療用プロジェクターの支持構造Support structure for medical projector
 本発明は医療用プロジェクターの支持構造に関する。 The present invention relates to a support structure for a medical projector.
 手術で使用される顕微鏡やカメラ等の医療機器は、フロアに設置されたスタンド装置から横方向に延びる支持アームの先端部に支持される。支持アームの先端部には複数の回転軸を有する保持アームが取付けられ、その保持アームの先端に医療機器の片方の側面が固定される。複数の回転軸を有する保持アームにより支持するため医療機器はその向きを任意に変更することができる。顕微鏡やカメラ等の医療機器は比較的小型のため、医療機器の片方の側面だけを保持アームにより所謂片持ち状態で支持しても問題ない。関連技術は日本国特許公開公報特開2017-6620号(特許文献1)に例示される。 Medical devices such as microscopes and cameras used in surgery are supported by the tip of a support arm that extends laterally from a stand device installed on the floor. A holding arm having a plurality of rotating shafts is attached to the tip of the support arm, and one side surface of the medical device is fixed to the tip of the holding arm. Since the medical device is supported by a holding arm having a plurality of rotation axes, the direction of the medical device can be arbitrarily changed. Since medical devices such as a microscope and a camera are relatively small, there is no problem if only one side of the medical device is supported in a so-called cantilever state by a holding arm. Related technology is exemplified in Japanese Patent Publication No. 2017-6620 (Patent Document 1).
 しかしながら近年では顕微鏡やカメラ等の機能を内蔵した大型の医療機器も開発されている。例えば、手術部位の臓器における蛍光画像を撮影し、それを可視画像化してプロジェクションマッピング技術により臓器に直接投影する医療用プロジェクターが開発されている。このように大型の医療機器の場合は片持ちでは支持が不安定になるため、両持ちで且つ向きを任意に変更可能な新たな支持構造の提案が待たれている。 However, in recent years, large medical devices with built-in functions such as a microscope and a camera have been developed. For example, a medical projector has been developed that takes a fluorescent image of an organ at a surgical site, visualizes it, and projects it directly onto the organ using a projection mapping technique. Thus, in the case of a large-sized medical device, the support becomes unstable if it is cantilevered, and a proposal of a new support structure that can be arbitrarily changed in both directions while being held is awaited.
 本発明によれば、大型の医療用プロジェクターを両持ちで確実に支持でき且つ支持した状態で向きを任意に変更可能な医療用プロジェクターの支持構造を提供することができる。 According to the present invention, it is possible to provide a support structure for a medical projector that can reliably support a large-sized medical projector with both ends and can arbitrarily change the orientation in a supported state.
 本発明の第1の技術的側面によれば、フロアに設置されたスタンド装置の横方向に延びる支持アームの先端部に、途中から先端側が二股状に分岐した保持アームを、支持アームの軸心に合致した第1回転軸を中心に回転自在に取付け、保持アームの先端側の両方の端部間に、支持アームの第1回転軸に直交する第2回転軸を中心にして回転自在な円筒部を取付け、該円筒部に、外輪と内輪との間に複数の転動体を介在させたリング状ベアリングの外輪部分を固定し、リング状ベアリングの内部に、下面より光線を照射する医療用プロジェクターを、リング状ベアリングの内輪部分に固定した状態で、リング状ベアリングの中心軸を中心にして回転自在に配置したことを特徴とする。 According to the first technical aspect of the present invention, a holding arm whose front end side branches in a bifurcated manner from the middle is provided at the front end portion of the support arm extending in the lateral direction of the stand device installed on the floor. A cylinder that is rotatable about a first rotation axis that matches the first rotation axis, and that is rotatable about a second rotation axis that is orthogonal to the first rotation axis of the support arm, between both ends on the distal end side of the holding arm. A medical projector that attaches the outer ring portion of the ring-shaped bearing in which a plurality of rolling elements are interposed between the outer ring and the inner ring, and irradiates light from the lower surface inside the ring-shaped bearing. Is fixed to the inner ring portion of the ring-shaped bearing and is arranged so as to be rotatable about the central axis of the ring-shaped bearing.
 本発明の第2の技術的側面によれば、医療用プロジェクターの第2回転軸方向における両方の側面に、第2回転軸を通過する状態で医療用プロジェクターの中心軸方向に沿って延びるレールを設け、該レールに対してレールの長手方向に沿って位置を変更自在なウェイトをそれぞれ設けたことを特徴とする。 According to the second technical aspect of the present invention, rails extending along the central axis direction of the medical projector in a state of passing through the second rotational axis are provided on both side surfaces in the second rotational axis direction of the medical projector. Each of the weights is provided with a weight whose position can be changed along the longitudinal direction of the rail.
 本発明の第3の技術的側面によれば、レールの下端部にスタンド装置或いは医療用プロジェクターを操作するための操作ハンドルを取付けたことを特徴とする。 According to a third technical aspect of the present invention, an operating handle for operating a stand device or a medical projector is attached to the lower end of the rail.

 本発明の好適な実施形態を図1~図10に基づいて説明する。以下において前後左右の方向性は図1に示された通りである。 A preferred embodiment of the present invention will be described with reference to FIGS. In the following, the front-rear and left-right directions are as shown in FIG.
 手術室内のフロア上に設置されているスタンド装置1は、ベース上で水平方向に回転自在なスタンド本体2を備えている。スタンド本体2には、前アーム3及び後アーム4を含む平行リンク機構Rが、前アーム3の途中に設定された回転軸5を中心にして回転自在に支持されている。 The stand device 1 installed on the floor in the operating room includes a stand body 2 that can be rotated horizontally on the base. A parallel link mechanism R including a front arm 3 and a rear arm 4 is supported on the stand body 2 so as to be rotatable about a rotation shaft 5 set in the middle of the front arm 3.
 平行リンク機構Rの上辺は支持アーム6の後側部分により形成され、支持アーム6はそのまま前方へ延びている。平行リンク機構Rの下辺は下アーム7の前側部分により形成され、下アーム7はそのまま後方へ延び、後端にはカウンタウェイト8が取付けられている。 The upper side of the parallel link mechanism R is formed by the rear portion of the support arm 6, and the support arm 6 extends forward as it is. The lower side of the parallel link mechanism R is formed by a front portion of the lower arm 7, the lower arm 7 extends rearward as it is, and a counterweight 8 is attached to the rear end.
 支持アーム6の先端部には、途中から先端側が二股状に分岐した保持アーム9が取付けられている。保持アーム9は支持アーム6の軸心に合致した第1回転軸Xを中心に回転自在に取付けられている。 At the tip of the support arm 6, a holding arm 9 whose tip is branched in a bifurcated manner is attached. The holding arm 9 is attached so as to be rotatable about a first rotation axis X that matches the axis of the support arm 6.
 保持アーム9の二股状に分岐した先端側の端部10間にはリング状の円筒部11が取付けられている。円筒部11はその最大直径部分が、第1回転軸Xに直交する第2回転軸Yを中心にした状態で、端部10に対して回転自在に取付けられている。 A ring-shaped cylindrical portion 11 is attached between the end portions 10 of the holding arm 9 which are bifurcated. The cylindrical portion 11 is rotatably attached to the end portion 10 in a state where the maximum diameter portion is centered on a second rotation axis Y orthogonal to the first rotation axis X.
 円筒部11の内面には複数の凸部12が円周方向に沿って形成されている。この凸部12上にリング状ベアリング13が取付けられている。リング状ベアリング13は、外輪14と内輪15との間に複数のコロ(転動体)16を介在させた構造で、その外輪14がネジ17により凸部12に固定されている。 A plurality of convex portions 12 are formed on the inner surface of the cylindrical portion 11 along the circumferential direction. A ring-shaped bearing 13 is mounted on the convex portion 12. The ring-shaped bearing 13 has a structure in which a plurality of rollers (rolling elements) 16 are interposed between the outer ring 14 and the inner ring 15, and the outer ring 14 is fixed to the convex portion 12 with screws 17.
 リング状ベアリング13の内部には医療用プロジェクター18が配置されている。医療用プロジェクター18は概略直方体で、その側面の周囲に6個の取付部品19が固定されており、その先端部がリング状ベアリング13の内輪15に下側からネジ20により固定されている。リング状ベアリング13の中心軸Zは前記第1回転軸X及び第2回転軸Yと直交し、医療用プロジェクター18はこの中心軸Zを中心に円筒部11及び外輪14に対して回転自在となる。 A medical projector 18 is disposed inside the ring-shaped bearing 13. The medical projector 18 is a substantially rectangular parallelepiped, and six attachment parts 19 are fixed around the side surface thereof, and the tip end portion is fixed to the inner ring 15 of the ring-shaped bearing 13 by screws 20 from below. The center axis Z of the ring-shaped bearing 13 is orthogonal to the first rotation axis X and the second rotation axis Y, and the medical projector 18 is rotatable with respect to the cylindrical portion 11 and the outer ring 14 about the center axis Z. .
 医療用プロジェクター18の第2回転軸Yの方向における両側面には、第2回転軸Yを通過した状態で、医療用プロジェクター18の中心軸Zの方向に沿って延びるレール21が固定されている。このレール21には長手方向に沿って複数のネジ穴22が形成されている。レール21には断面コ字状のウェイト23が設けられる。ウェイト23には円孔24が形成され、そこからネジ部25を挿入して任意のネジ穴22に螺合することにより、ウェイト23の位置をレール21の長手方向に沿って変更することができる。 Rails 21 extending along the direction of the central axis Z of the medical projector 18 in a state of passing through the second rotational axis Y are fixed to both side surfaces of the medical projector 18 in the direction of the second rotational axis Y. . A plurality of screw holes 22 are formed in the rail 21 along the longitudinal direction. The rail 21 is provided with a weight 23 having a U-shaped cross section. A circular hole 24 is formed in the weight 23, and the position of the weight 23 can be changed along the longitudinal direction of the rail 21 by inserting a screw portion 25 therefrom and screwing it into an arbitrary screw hole 22. .
 レール21が第2回転軸Yを通過する状態で延びるため、ウェイト23の位置を第2回転軸Yを境として両側へ移動させることができる。そのため、図9で示すように、医療用プロジェクター18の第2回転軸Yを中心とした上下の重量W1、W2を等しくすることで、第2回転軸Yを中心とした回転方向でのバランス調整を行うことができる。場合によっては、左右のウェイト23のいずれか一方の重さを変えることにより、医療用プロジェクター18の第1回転軸Xを中心とした回転方向でのバランス調整も行うことができる。 Since the rail 21 extends while passing through the second rotation axis Y, the position of the weight 23 can be moved to both sides with the second rotation axis Y as a boundary. Therefore, as shown in FIG. 9, by adjusting the upper and lower weights W1 and W2 around the second rotation axis Y of the medical projector 18, the balance adjustment in the rotation direction around the second rotation axis Y is performed. It can be performed. In some cases, by changing the weight of one of the left and right weights 23, balance adjustment in the rotation direction around the first rotation axis X of the medical projector 18 can also be performed.
 レール21の下端部には操作ハンドル26が左右にそれぞれ取付けられている。この操作ハンドル26はスタンド装置1の各回転部における電磁クラッチや医療用プロジェクター18を操作するためのものである。操作ハンドル26が剛性の高いレール21の下端部に取付けられているため、操作ハンドル26の取付剛性が高い。 An operation handle 26 is attached to the left and right of the lower end of the rail 21, respectively. The operation handle 26 is for operating the electromagnetic clutch and the medical projector 18 in each rotating part of the stand device 1. Since the operation handle 26 is attached to the lower end portion of the highly rigid rail 21, the attachment rigidity of the operation handle 26 is high.
 医療用プロジェクター18の側面部には、その下端周囲に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から放射方向に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。この照明27は白色光Hを照射してドクターDの手元の手術部位をあらゆる方向から照らして、ドクターDの手の陰により手術部位が暗くなることを解消するためのものである。 On the side surface of the medical projector 18, seven illuminations 27 are arranged around the lower end of the medical projector 18 in a state of being separated from the medical projector 18 in a radial direction and arranged circumferentially by a support bar 28 having different lengths. ing. The illumination 27 irradiates white light H to illuminate the surgical site at hand of Dr. D from all directions, and eliminates the fact that the surgical site becomes dark due to the shadow of Dr. D's hand.
 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の下面には窓29が形成され、その周囲には特定波長の励起光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. A window 29 is formed on the lower surface of the medical projector 18, and an excitation light illumination 30 that emits excitation light E having a specific wavelength is provided around the window 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(蛍光強度によっては点灯する場合もある)。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 (it may be turned on depending on the fluorescence intensity). 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.
 この医療用プロジェクター18は二股状に分岐した保持アーム9により円筒部11及びリング状ベアリング13を介して両持ち状態で支持されるため、支持状態が確実である。 Since this medical projector 18 is supported in a double-sided manner by the holding arm 9 branched in a bifurcated manner through the cylindrical portion 11 and the ring-shaped bearing 13, the support state is reliable.
 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、二股状に分岐した保持アームにより医療用プロジェクターを両持ち状態で確実に支持することができる。医療用プロジェクターが、第1回転軸を中心に保持アームごと回転し、第2回転軸を中心にリング状ベアリングごと回転し、リング状ベアリングの中心軸を中心に回転するため、医療用プロジェクターの向きを任意に変更することができる。 According to the first technical aspect of the present invention, the medical projector can be reliably supported in the both-sided state by the holding arm branched in a bifurcated shape. The medical projector rotates with the holding arm around the first rotation axis, rotates with the ring bearing around the second rotation axis, and rotates around the center axis of the ring bearing. Can be changed arbitrarily.
 本発明の第2の技術的側面によれば、レールに沿ってウェイトの位置を変更することにより、医療用プロジェクターの第2回転軸を中心とした回転方向でのバランス調整を行うことができる。 According to the second technical aspect of the present invention, by changing the position of the weight along the rail, it is possible to adjust the balance in the rotation direction around the second rotation axis of the medical projector.
 本発明の第3の技術的側面によれば、操作ハンドルが剛性の高いレールの下端部に取付けられているため、操作ハンドルの取付剛性を高めることができる。 According to the third technical aspect of the present invention, since the operating handle is attached to the lower end of the highly rigid rail, the mounting rigidity of the operating handle can be increased.
