Abstract

PROBLEM TO BE SOLVED: To solve such a problem that liquid falling down a wall surface of a C arm often infiltrates inside an X-ray tube cover and an X-ray detector cover from a gap thereof, however, hospital officials cannot open the covers, and it is hard for them to clean the inside thereof, so that pathogenic bacteria and other saprophytes are proliferated inside the covers.SOLUTION: An X-ray tube retaining device according to the present invention includes: an arm for retaining an X-ray tube; and a waterproof member closely fitted to at least one surface of the arm. The waterproof member is a liquid-impermeable material in itself, and the waterproof member and the X-ray tube are covered by a cover.SELECTED DRAWING: Figure 3

Description

この発明は、Ｘ線管又はＸ線検出器を保持する保持装置に関し、特に、Ｘ線管又はＸ線検出器のカバー内部への液体の侵入を防止する技術に関する。 The present invention relates to a holding device that holds an X-ray tube or an X-ray detector, and more particularly, to a technique for preventing liquid from entering the cover of the X-ray tube or the X-ray detector.

従来のX線透視撮影装置は、X線管と、X線検出器とを対向保持するCアームと、当該X線管を覆うX線管カバーと、X線検出器又はその制御部を覆うX線検出器カバーとを有している(例えば特許文献１)。
従来のX線透視撮影装置を手術室や血管造影室で使用する際、被検者の血液、生理食塩水、造影剤などがX線透視撮影装置にかかる場合がある。病原菌その他の雑菌が繁殖したり、その菌により他の被検者や術者が感染したりする恐れがある。従って、X線透視撮影装置に付着した血液等の液体は、検査終了後に全てふき取る必要がある。 A conventional X-ray fluoroscopic apparatus includes an X-ray tube, a C-arm that holds the X-ray detector opposite to each other, an X-ray tube cover that covers the X-ray tube, and an X-ray detector that covers the X-ray detector or its control unit. A line detector cover (for example, Patent Document 1).
When a conventional X-ray fluoroscopic apparatus is used in an operating room or an angiography room, a subject's blood, physiological saline, contrast medium, or the like may be applied to the X-ray fluoroscopic apparatus. Pathogens and other miscellaneous bacteria may propagate, and the bacteria may infect other subjects and surgeons. Therefore, it is necessary to wipe off all the liquid such as blood adhering to the X-ray fluoroscopic apparatus after the examination is completed.

しかし、従来のX線透視撮影装置は、Cアームの壁面を伝ってX線管カバーやX線検出器カバーの隙間から内部に液体が浸潤することがあった。これらカバーは、病院関係者が開けることができず、内部の清掃が困難であった。そのため、病原菌その他の雑菌は、カバー内部で繁殖してしまう問題があった。
また、この問題を解決するために、当該隙間を塞ぐように、カバーの外から、隙間部分に樹脂コーキングをすることもあった。しかし、当該樹脂コーキングは、カバーとＣアームとが接着されてしまうため、X線管やX線検出器のメンテナンスの際、X線管カバーやX線検出器カバーを開閉することを阻害するという問題があった。
本発明は、上記問題を解決し、清掃の容易性及びメンテナンス性を両立したX線管又はX線検出器の保持装置を提供することを目的とする。 However, in conventional X-ray fluoroscopic apparatuses, liquid may infiltrate into the inside through the gap between the X-ray tube cover and the X-ray detector cover along the wall of the C arm. These covers could not be opened by hospital personnel and it was difficult to clean the inside. For this reason, pathogens and other germs have a problem of breeding inside the cover.
In addition, in order to solve this problem, resin caulking may be applied to the gap portion from the outside of the cover so as to close the gap. However, since the cover and the C-arm are bonded, the resin caulking prevents the X-ray tube cover and the X-ray detector cover from being opened and closed during maintenance of the X-ray tube and the X-ray detector. There was a problem.
An object of the present invention is to provide a holding device for an X-ray tube or an X-ray detector that solves the above-described problems and has both easy cleaning and maintainability.

上記課題を解決するために、本発明は、X線管を保持するアームと、前記アームの少なくとも一面に密着する防水部材とを有し、前記防水部材は、それ自体液体を透過しない素材であり、前記X線管はカバーで覆われており、前記防水部材は、前記アーム及びカバーのいずれか一方にのみ固定されていることを特徴とする。
上記手段により、アームの一面を伝ってくる液体の侵入を、防水部材によって防ぐことができるため、清掃が容易になる。加えて、カバーの着脱に影響を与えないため、メンテナンス性を維持できる。 In order to solve the above problems, the present invention includes an arm that holds an X-ray tube and a waterproof member that is in close contact with at least one surface of the arm, and the waterproof member is a material that does not permeate liquid. The X-ray tube is covered with a cover, and the waterproof member is fixed to only one of the arm and the cover.
By the above-mentioned means, the intrusion of the liquid traveling on one surface of the arm can be prevented by the waterproof member, so that cleaning becomes easy. In addition, since it does not affect the attachment / detachment of the cover, maintainability can be maintained.

また、前記アームはC型のアームであり、前記防水部材は、当該アームの内周面に密着していることを特徴とする。
Cアームの場合、液体が内周面を伝うことが多いため、防水部材を内周面に密着していることにより、効果的に液体の侵入を防ぐことが出来る。 The arm is a C-type arm, and the waterproof member is in close contact with the inner peripheral surface of the arm.
In the case of the C-arm, since the liquid often travels along the inner peripheral surface, the intrusion of the liquid can be effectively prevented by closely attaching the waterproof member to the inner peripheral surface.

また、前記C型のアームは、外周面、内周面、及び両側面の４面を有し、前記防水部材は、当該アームの内周面及び両側面に密着していることを特徴とすることを特徴とする。
Cアームの内周面を伝って、防水部材でせき止められた液体は、側面に逃げる場合があり、その際、Cアームの向きによってはカバーの内部に侵入する場合がある。防水部材が両側面にも及んでいれば、より効果的に液体の侵入を防ぐことが出来る。 The C-shaped arm has four surfaces, an outer peripheral surface, an inner peripheral surface, and both side surfaces, and the waterproof member is in close contact with the inner peripheral surface and both side surfaces of the arm. It is characterized by that.
The liquid dammed up by the waterproof member along the inner peripheral surface of the C arm may escape to the side surface, and at that time, depending on the orientation of the C arm, the liquid may enter the inside of the cover. If the waterproof member extends to both side surfaces, the liquid can be prevented from entering more effectively.

また、前記防水部材は、前記カバーの内壁面にも密着していることを特徴とする。
これにより、防水部材を乗り越えて液体が侵入するのを防ぐことが出来ため、特に効果的に液体の侵入を防ぐことができる。 The waterproof member is also in close contact with the inner wall surface of the cover.
Thereby, it is possible to prevent the liquid from entering over the waterproof member, and thus it is possible to prevent the liquid from entering particularly effectively.

更に、本発明のX線検出器保持装置は、X線検出器を保持するアームと、前記アームの少なくとも一面に密着する防水部材とを有し、前記防水部材は、それ自体液体を透過しない素材であり、前記防水部材及び前記X線検出器は、カバーで覆われていることを特徴とする。
X線管の場合と同様の効果を奏する。 Furthermore, the X-ray detector holding device of the present invention has an arm that holds the X-ray detector and a waterproof member that is in close contact with at least one surface of the arm, and the waterproof member itself does not transmit liquid. The waterproof member and the X-ray detector are covered with a cover.
The same effect as in the case of an X-ray tube is achieved.

本発明のX線管又はX線検出器の保持装置によれば、清掃の容易性及びメンテナンス性の両立を図ることができる。 According to the X-ray tube or X-ray detector holding device of the present invention, both ease of cleaning and maintainability can be achieved.

図１に示すように、本発明にかかる保持装置１は、本体に対して回転や平行移動できる状態で保持されたCアーム2と、Cアーム2の一端に保持されたX線検出器3と、その他端に保持されたX線管4と、前記X線管を覆うX線管カバー5と、X線検出器の一部を覆うX線検出器カバー7とを有している。なお、保持装置１を含む図１全体の装置は、一般にX線透視撮影装置と呼ばれている。 As shown in FIG. 1, a holding device 1 according to the present invention includes a C arm 2 held in a state where it can be rotated and translated with respect to a main body, and an X-ray detector 3 held at one end of the C arm 2. The X-ray tube 4 is held at the other end, the X-ray tube cover 5 covers the X-ray tube, and the X-ray detector cover 7 covers a part of the X-ray detector. Note that the entire apparatus shown in FIG. 1 including the holding apparatus 1 is generally called an X-ray fluoroscopic apparatus.

図２は、X線管カバー5周辺の拡大図である。Cアーム2の端にX線管4が取り付けられ、その上にカバー5が取り付けられている。本実施形態では、X線管4には、電圧の昇圧回路が付属しているため(一般にモノタンク型という)、下方に大きくせり出しているが、特にこの種の構成に限定されることはない。 FIG. 2 is an enlarged view around the X-ray tube cover 5. An X-ray tube 4 is attached to the end of the C arm 2, and a cover 5 is attached thereon. In the present embodiment, since the voltage booster circuit is attached to the X-ray tube 4 (generally referred to as a mono tank type), the X-ray tube 4 protrudes downward greatly, but is not particularly limited to this type of configuration.

図３は、図２のX線管カバー５を開けた状態の図である。Cアーム2の端部には、X線管４と、その開口部に取り付けられ、X線束を絞るためのコリメータ９とが、取り付けられている。また、Cアーム2には、略コの字をしたシリコン樹脂製の防水部材８が、Cアーム2の両側面からネジ７Mで固定されている。 FIG. 3 is a view showing a state in which the X-ray tube cover 5 of FIG. 2 is opened. An X-ray tube 4 and a collimator 9 for narrowing the X-ray bundle are attached to the end of the C-arm 2. Further, a substantially U-shaped silicone resin waterproofing member 8 is fixed to the C arm 2 with screws 7M from both side surfaces of the C arm 2.

図3の右下に、防水部材８単体の拡大図を示す。防水部材８は、液体がX線管4の方に侵入しないように、Cアーム2に密着させる。例えば、防水部材８を引っ張りながらネジ7Mを締めることにより、弾性によって防水部材８がCアーム2の表面に押し当てられるため、密着状態を維持することができる。なお、防水部材８とCアーム2とを接着剤で固定したり、グリスなどを介在させたりするような場合も、「密着」に含まれるものとする。更に一般化すれば、本発明における「密着」とは、防水部材とアーム表面との間に、液体が侵入するほどの隙間がないことを意味する。 An enlarged view of the waterproof member 8 alone is shown in the lower right of FIG. The waterproof member 8 is brought into close contact with the C arm 2 so that liquid does not enter the X-ray tube 4. For example, by tightening the screw 7M while pulling the waterproof member 8, the waterproof member 8 is pressed against the surface of the C arm 2 by elasticity, so that the close contact state can be maintained. In addition, the case where the waterproof member 8 and the C arm 2 are fixed with an adhesive or grease is interposed is also included in the “contact”. More generally, the “close contact” in the present invention means that there is no gap between the waterproof member and the arm surface to allow liquid to enter.

本実施形態におけるCアーム2は、図４に示すように、内周面２iと、外周面２ｏと、側面２_Ｌ及び２_ｒとを有している。また、防水部材８は、図３右下に示すように、コの字状となっており、内周面２iと、側面２_Ｌ及び２_ｒとに密着するように取り付けられる。従って、内周面２iを伝って流れてきた液体は、防水部材８でせき止められ、側面２_Ｌまたは２_ｒを伝って床に流れ落ちる。従って、液体が溜まらず、Ｘ線管カバー５を開閉することなく清掃を行うことができる。 C-arm 2 in the present embodiment, as shown in FIG. 4, has an inner peripheral surface 2i, and the outer peripheral surface 2o, and side 2 _L and 2 _r. Further, the waterproof member 8, as shown in the lower right 3, has a U-shaped, and the inner peripheral surface 2i, mounted so as to be in close contact with the side surface 2 _L and 2 _r. Thus, the liquid that has flowed along the inner circumferential surface 2i is dammed up by the waterproof member 8 flows down along the side 2 _L or 2 _r to the floor. Therefore, liquid does not accumulate and cleaning can be performed without opening and closing the X-ray tube cover 5.

更に、図3に示すように、Ｘ線管カバー５の端部における内壁面5kと、防水部材８の縁部８ｋとが接する位置で、Cアーム2に対してＸ線管カバー５及び防水部材８を取り付ける事により、Ｘ線管カバー５と、防水部材８との隙間からの液体の侵入を防ぐことができる。 Further, as shown in FIG. 3, the X-ray tube cover 5 and the waterproof member with respect to the C arm 2 at a position where the inner wall surface 5 k at the end of the X-ray tube cover 5 and the edge 8 k of the waterproof member 8 contact each other. By attaching 8, it is possible to prevent liquid from entering from the gap between the X-ray tube cover 5 and the waterproof member 8.

なお、本実施形態では、防水部材は樹脂製としたが、それ自体が水分を透過しない部材であれば特に限定されない。ただし、弾性を有する部材であれば、カバーやアームに多少の凹凸があっても密着を確保しやすいことに加え、アーム、カバー、防水部材の各取り付け位置誤差を吸収することができるので、好適である。 In the present embodiment, the waterproof member is made of resin. However, the waterproof member is not particularly limited as long as the member itself does not transmit moisture. However, if it is a member having elasticity, it is easy to ensure adhesion even if there are some unevenness on the cover or arm, and it is possible to absorb each mounting position error of the arm, cover, waterproof member, so it is suitable It is.

また、本実施形態では、Ｘ線管４側に防水部材８を配置することとしたが、同様の構成により、Ｘ線検出器３側に防水部材を配置することとしてもよい。 In this embodiment, the waterproof member 8 is arranged on the X-ray tube 4 side. However, the waterproof member may be arranged on the X-ray detector 3 side by the same configuration.

また、本実施形態では、防水部材８は、コの字状となっており、内周面２iと、側面２_Ｌ及び２_ｒとに密着するように取り付けられることとしたが、いずれか一面だけであっても、その面を介した液体の侵入を防ぐことができる。また、防水部材はアーム側ではなく、カバー側に取り付けるようにしてもよい。その場合、防水部材は、アームに固定しないようにすれば、カバーの脱着が可能となる。ただし、カバー側に防水部材を取り付けると、アームとの密着を確保するために、より一層の加工精度・取り付け精度が要求される。よって、防水部材は、アーム側に取り付けることが望ましい。なお、カバーは、アームに取り付けても、Ｘ線管に取り付けてもよい。 Further, in the present embodiment, the waterproof member 8 has a U-shaped, and the inner peripheral surface 2i, it is assumed that mounted so as to be in close contact with the side surface 2 _L and 2 _r, only any one side Even so, it is possible to prevent liquid from entering through the surface. The waterproof member may be attached to the cover side instead of the arm side. In that case, if the waterproof member is not fixed to the arm, the cover can be attached and detached. However, when a waterproof member is attached to the cover side, further processing accuracy and attachment accuracy are required to ensure close contact with the arm. Therefore, it is desirable to attach the waterproof member to the arm side. The cover may be attached to an arm or an X-ray tube.

また、本実施形態では、防水部材８はＸ線管カバー５で覆われている位置に設けることとしたが、Ｘ線管カバー５の外側に配置しても良い。ただし、Ｘ線管カバー５の内部に液体が侵入することを防止するため、防水部材８の縁部８ｋと対向する面と、Ｘ線管カバー５の外壁とを接する位置に配置することが望ましい。
ただし、防水部材８をＸ線管カバー５で覆うと、液体が付着するＣアーム２の内周面２iがフラットになり、清掃が容易となることに加え、見た目もすっきりとするため、より好ましい。 In the present embodiment, the waterproof member 8 is provided at a position covered with the X-ray tube cover 5, but may be disposed outside the X-ray tube cover 5. However, in order to prevent liquid from entering the inside of the X-ray tube cover 5, it is desirable to arrange the surface facing the edge 8 k of the waterproof member 8 and the outer wall of the X-ray tube cover 5. .
However, it is more preferable that the waterproof member 8 is covered with the X-ray tube cover 5 because the inner peripheral surface 2i of the C arm 2 to which the liquid adheres becomes flat and easy to clean, and also looks clean. .

更に、本実施形態では、アームとしてＣアームを例示したが、例えば天井懸垂型のＸ線管保持装置のように、直線形状のアームであってよく、Ｘ線管のみを保持する機構であっても良い。更には、例えば立位ブッキー装置のように、Ｘ線検出器のみを保持するアームや支柱にも適用可能である。
その他、Ｘ線管やＸ線検出器を保持するアームであって、Ｘ線管又はＸ線検出器の少なくとも一部を覆うカバーを備える機構である限りにおいて、その実施形態を種々変更可能である。 Furthermore, in the present embodiment, the C-arm is exemplified as the arm, but it may be a linear arm, such as a ceiling-suspended X-ray tube holding device, and is a mechanism that holds only the X-ray tube. Also good. Furthermore, the present invention can also be applied to an arm or a column that holds only the X-ray detector, such as a standing bucky device.
In addition, the embodiment can be variously modified as long as it is an arm that holds an X-ray tube or an X-ray detector and includes a cover that covers at least a part of the X-ray tube or the X-ray detector. .
