医療用Ｘ線装置による撮影で、本発明のＸ線用貼付剤により、患部の体表面上の位置を確定する外科手術。A surgical procedure in which the location of the affected area on the body surface is determined using the X-ray patch of the present invention through imaging with a medical X-ray device.

医療用Ｘ線装置による診断で肝臓に癌が見つかった場合、外科的には開腹手術、腹腔鏡手術、そしてラジオ波焼灼手術等が施行される。
ラジオ波焼灼手術ではＸ線、電磁波、超音波等による各種診断後、ラジオ波焼灼プローブ先端の針を体表面から穿刺し、患部を焼灼する。When cancer is found in the liver through diagnosis using a medical X-ray device, surgical procedures such as open surgery, laparoscopic surgery, and radiofrequency ablation surgery are performed.
In radiofrequency ablation surgery, after various diagnoses using X-rays, electromagnetic waves, ultrasound, etc., a needle at the tip of a radiofrequency ablation probe is inserted through the body surface to cauterize the affected area.

食品、医薬品工場、レストラン、外食産業における作業員の絆創膏混入事故をＸ線異物検知機並びに金属検知機を用いて未然に防止することを可能にした金属を含有した絆創膏がある。There is a metal-containing bandage that has made it possible to prevent accidents involving bandages by workers in the food and pharmaceutical factories, restaurants, and food service industries by using X-ray foreign object detectors and metal detectors.

患者の患部がＸ線影像には写っても、体表面上から見て患部の位置を正確に指し示すのは医師にとって難しい。
肝臓癌患者手術前のＸ線装置による診断で、ラジオ波焼灼プローブ先端を穿刺する体表面の位置は、術者にとって手術直前まで不確定である。Even if a patient's affected area appears on an X-ray image, it is difficult for a doctor to accurately pinpoint the location of the affected area when viewed from the body surface.
When diagnosing a liver cancer patient using an X-ray device before surgery, the position on the body surface where the tip of the radiofrequency ablation probe will be punctured is uncertain for the operator until just before the surgery.

布、膜、箔、フィルム、或いは板状材料に、図形、文字、記号の何れかの形状をしたＸ線不透過性物質を貼付、塗付、包埋、内包、或いは染み込ませたＸ線用貼付剤をＸ線撮影時に使用する。Ｘ線影像から患者体表面の手術位置を特定する事により、術者の手術手順を容易にする。本発明のＸ線用貼付剤は患者の皮膚に優しい絆創膏の様な、ウレタン不織布材料使用が好ましい。For X-rays, an X-ray opaque substance in the shape of a figure, character, or symbol is pasted, painted, embedded, included, or impregnated on a cloth, membrane, foil, film, or plate-like material. The patch is used during X-ray photography. By specifying the surgical position on the patient's body surface from the X-ray image, the surgical procedure for the operator is facilitated. The X-ray patch of the present invention preferably uses a urethane nonwoven material, such as a bandage, which is gentle on the patient's skin.

本発明のＸ線用貼付剤の患者皮膚への粘着剤として、アクリル系粘着剤、ゴム系粘着剤、シリコーン系等の医療用粘着剤等がある。Ｘ線不透過性物質としてはアルミニウム、銅、等がある。Examples of the adhesive for applying the X-ray patch of the present invention to the patient's skin include medical adhesives such as acrylic adhesives, rubber adhesives, and silicone adhesives. Examples of the radiopaque material include aluminum, copper, and the like.

ＣＴ（Ｃｏｍｐｕｔｅｒ Ｔｏｍｏｇｒａｐｈｙ）Ｘ線断層診断装置による撮影時に本発明のＸ線用貼付剤を１ヶ所以上、肝臓周辺と考えられる体表面に、貼付する。Ｘ線影像には患部と共に目印となるＸ線用貼付剤の図形、文字、又は記号が写っており、癌患部との位置関係が容易に計測出来る。At the time of imaging using a CT (Computer Tomography) X-ray tomography diagnostic device, the X-ray patch of the present invention is applied to one or more body surfaces considered to be around the liver. The X-ray image shows the affected area as well as the marks, letters, or symbols of the X-ray patch, making it easy to measure the positional relationship with the cancer-affected area.

つまり、本発明は、布、膜、箔、フィルム、シート、テープ、或いは板状の材料に、図形、文字、記号の何れかの形状をした電磁波感応物質を貼付、塗付、包埋、内包、或いは染み込ませた事を特徴とする電磁波感応貼付剤である。In other words, the present invention involves attaching, painting, embedding, or including an electromagnetic wave-sensitive material in the shape of a figure, character, or symbol to a cloth, membrane, foil, film, sheet, tape, or plate-like material. , or an electromagnetic wave-sensitive patch characterized by being impregnated with it.

本発明では、電磁波は元より、磁力線に対しても同様の形態や使用方法が考えられ、磁力波感応貼付剤も提示、提供出来る。In the present invention, similar forms and usage methods can be considered not only for electromagnetic waves but also for magnetic lines of force, and magnetic force wave sensitive patches can also be presented and provided.

本発明の電磁波感応貼付剤や磁力波感応貼付剤を人や動物の体表に貼付し、その電磁波、或いは磁力線による体内診断を基に、体内の病変や患部或いは異物の体表上での位置を確定する方法を提供する。The electromagnetic wave-sensitive patch or magnetic force wave-sensitive patch of the present invention is applied to the body surface of a person or animal, and based on in-vivo diagnosis using the electromagnetic waves or magnetic field lines, the position of lesions, affected areas, or foreign objects in the body can be determined on the body surface. Provide a method to determine the

ＣＴ装置による撮影時に本発明のＸ線用貼付剤を使用する事により、患部位置を確定し、術者がラジオ波焼灼プローブ先端進入がし易くなる。
更に、ＣＴ影像で、患部と体表間の距離が出ているので手術がより簡単に施行可能となる。By using the X-ray patch of the present invention during imaging with a CT device, the position of the affected area can be determined and the operator can easily enter the tip of the radiofrequency ablation probe.
Furthermore, CT images show the distance between the affected area and the body surface, making surgery easier.

医療従事者にとって、図形、文字、記号等の形状をしたＸ線不透過性物質はＸ線影像の中で判別し易く、診断に間違いを起こさない。
本発明のＸ線用貼付剤はＸ線影像に伴う診断に役立ち、外科手術の時間短縮、創口縮小、創口位置決定、等を可能にする。For medical personnel, X-ray opaque substances in the shape of figures, letters, symbols, etc. are easy to distinguish in X-ray images and do not cause errors in diagnosis.
The X-ray patch of the present invention is useful for diagnosis based on X-ray images, and enables shortening of surgical operation time, wound reduction, wound position determination, and the like.

図１はＸ線用貼付剤の１例であり、貼付剤Ａ、長方形のＸ線難透過性物質Ｂは上下２枚、切り取り部Ｃで構成される。FIG. 1 shows an example of an X-ray patch, in which a patch A, a rectangular X-ray poorly permeable substance B are composed of two sheets, an upper and a lower sheet, and a cutout section C.

図２はＸ線用貼付剤の１例であり、Ａは貼付剤、Ｘ線不透過性物質はＢは２枚十字に貼ってあり、図１の様な切り取り部Ｃは無い。FIG. 2 shows an example of an X-ray patch, in which A is a patch, B is two X-ray opaque substances pasted in a cross pattern, and there is no cutout C as in FIG.

図３はＸ線不透過性物質が丸型のシート状、或いは板状で、裏面に粘着剤を塗付したＸ線用貼付剤である。FIG. 3 shows an X-ray patch in which the X-ray opaque material is in the form of a round sheet or plate, and an adhesive is applied to the back side.

図４はＸ線不透過性物質Ｄを円形にして、中心に切り取り部Ｃを設け、ドーナツ状にし、裏面に粘着剤を塗付したＸ線用貼付剤である。FIG. 4 shows an X-ray patch in which an X-ray opaque substance D is made circular, a cutout C is provided in the center, it is shaped like a doughnut, and an adhesive is applied to the back side.

図５はＸ線不透過性物質Ｄを円形にして、切り取り部Ｃを設け、ピザの一片を切り取った様な図形としたＸ線不透過性物質Ｄのみの一例である。本発明のＸ線不透過性物質の形状は色々考えられるので、この形状には拘らない。FIG. 5 shows an example of only the X-ray opaque material D, which is made into a circular shape and provided with a cutout portion C so as to have a shape resembling a piece of pizza cut out. Since various shapes can be considered for the X-ray opaque substance of the present invention, the present invention is not limited to this shape.

図６は肝癌のＣＴ影像で、本発明の図１のＸ線用貼付剤を用いた人体正面の簡略図である。Ｘ線用貼付剤ＲとＬ及び患部Ｔがある例である。患部Ｔの縦軸とＸ線用貼付剤Ｒ－Ｌ間の線上で交差するＫ点が決まる。そしてＴ－Ｋ間、Ｌ－Ｋ間、Ｒ－Ｋ間、が求められる。すると体表上に患部Ｔの位置を記す事が出来る。FIG. 6 is a CT image of liver cancer, which is a simplified front view of a human body using the X-ray patch of FIG. 1 of the present invention. This is an example in which there are X-ray patches R and L and an affected area T. A point K that intersects on the line between the vertical axis of the affected area T and the X-ray patch RL is determined. Then, the distances between T and K, between L and K, and between R and K are determined. Then, the position of the affected area T can be marked on the body surface.

ＣＴ影像で患部Ｔの深さが出ているので、ラジオ波焼灼手術時にプローブ先端を皮膚直下、垂直に進められる。Since the depth of the affected area T is visible in the CT image, the tip of the probe can be advanced vertically just below the skin during radiofrequency ablation surgery.

本発明は医療用貼付剤であり、Ｘ線用貼付剤にＸ線不透過性物質及び切り取り部を備えている。本発明のＸ線用貼付剤は丸、四角、長方形等のみに拘らない。本発明の医療用Ｘ線用貼付剤裏面には、患者体表に装着可能な様に、粘着剤が付いている。The present invention is a medical patch, which includes an X-ray patch including an X-ray opaque material and a cutout. The X-ray patch of the present invention is not limited to a round, square, or rectangular shape. An adhesive is attached to the back side of the medical X-ray patch of the present invention so that it can be attached to the patient's body surface.

図面３及び図面４のＸ線不透過性物質ＤのみのＸ線用貼付剤も可能ではあるが、医療関係者にとっては、図１の様な絆創膏状のＸ線用貼付剤の方が取扱い易いと考えられる。Although it is possible to use an X-ray patch containing only the radiopaque material D shown in Figures 3 and 4, it is easier for medical personnel to handle a bandage-like X-ray patch as shown in Figure 1. it is conceivable that.

医療用絆創膏（ニチバン株式会社 商品名ケアリーヴ）丸型で直径２２ｍｍを使用した。絆創膏の止血ガーゼを外した。図１の様にＸ線不透過性物質Ｂとしてアルミ箔で大きさ２ｘ１８ｍｍを１枚、絆創膏中心から上下放射状に貼付した。中心に切り取り部Ｃ、直径３ｍｍ、を設け、図１の様なＸ線用貼付剤を作成した。切り取り部Ｃは照準用であり、体表に皮膚マーカーや皮膚ペン等で目印を体表に記す事が出来る。。A medical bandage (trade name: Careleve, manufactured by Nichiban Co., Ltd.) was used in a round shape with a diameter of 22 mm. I removed the hemostatic gauze from the bandage. As shown in FIG. 1, one piece of aluminum foil with a size of 2 x 18 mm was pasted radially upward and downward from the center of the bandage as X-ray opaque material B. A cutout C with a diameter of 3 mm was provided at the center, and an X-ray patch as shown in FIG. 1 was prepared. The cutout C is for aiming, and marks can be marked on the body surface with a skin marker, skin pen, etc. .

実施例１と同様に丸型で直径２２ｍｍ医療用絆創膏の止血ガーゼを外し作成した。図２の様にＸ線不透過性物質Ｂとしてアルミニウム箔大きさ２ｘ１８ｍｍを２枚、十字に貼付し、Ｘ線用貼付剤を作成した。切り取り部は無くてもＣＴ影像上で位置関係は測定できる。As in Example 1, a round medical bandage with a diameter of 22 mm was prepared by removing the hemostatic gauze. As shown in FIG. 2, two pieces of aluminum foil with a size of 2 x 18 mm were pasted as X-ray opaque material B in a cross pattern to create an X-ray patch. Even without a cutout, the positional relationship can be measured on the CT image.
