Abstract

PROBLEM TO BE SOLVED: To solve such a problem that a position of a body surface to which a radio wave ablation probe tip is inserted is undecided for an operator until the time immediately before the surgery in diagnosis by a CT (Computer Tomography) X-ray tomographic diagnostic apparatus before the surgery for a liver cancer patient, and even though a cancer lesion part can be determined with the CT apparatus before the surgery in the radio wave ablation surgery, it is difficult for the operator to decide the position of insertion of the radio wave ablation probe in a case where the cancer lesion part is small, for example, being 10 mm or smaller.

SOLUTION: In order to solve the problem, a patch for X-ray that has the shape of a diagram, character, symbol, or the like according to the present invention is attached to the belly part of a patient for marking the position on the body surface and imaged at the time of using a CT apparatus. The diagram, character, symbol, or the like can be easily distinguished from image noise. An affected portion and an X-ray impermeable object are simultaneously captured in CT imaging of the front surface, the insertion position of a radio wave ablation probe tip can be easily decided with the positional relation between the affected portion and the patch for X-ray, surgery is made easy, and the therapeutic effect is improved.

Description

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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. .

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.

A circular aluminum patch D as shown in FIG. 3 was created by cutting out a circle with a diameter of 10 mm from a tape made of aluminum foil coated with an acrylic adhesive (manufactured by Teraoka Seisakusho Co., Ltd.). For attachment to the skin, the hemostatic gauze used in Examples 1 and 2 was removed and adhered to the bandage to form an X-ray patch.

A donut-shaped X-ray patch D as shown in FIG. 4 was prepared by cutting out a circle with a diameter of 10 mm from an aluminum foil tape (Teraoka Seisakusho Co., Ltd.), and then cutting out a center part with a diameter of 3 mm. The central cutout C is also a cutout for marking marks on the body surface with a skin marker or skin pen. To attach it to the skin, remove the hemostatic gauze from the bandage used in Examples 1 and 2, cut out a 3 mm diameter cutout, and glue it along the cutout C in Figure 4 and the cutout of the bandage to make an X-ray adhesive. It was used as a drug.

A donut-shaped adhesive patch D as shown in FIG. 4 was prepared by cutting out a circle with a diameter of 10 mm from an aluminum foil tape (Teraoka Seisakusho Co., Ltd.), and then cutting out the center with a diameter of 3 mm. The central cutout C is also a cutout for marking marks on the body surface with a skin marker or skin pen.

The X-ray patch of the present invention is for medical use, and when used during CT imaging, it makes it possible to mark the surgical position of the patient's affected area on the body surface with a skin marker or skin pen.
