[0020] The following will describe the solutions provided in this specification in conjunction with the drawings.

[0021] An embodiment of the present invention provides an X-ray positioning sticker, which includes a rectangular positioning sticker body and a plurality of through holes provided on the rectangular positioning sticker body, wherein the plurality of through holes are arranged in a matrix; Figure 3a As shown, the rectangular positioning sticker body includes a rectangular release paper 1, an adhesive layer 2, a metal foil layer 3, a polymer film layer 4 and a silk screen layer arranged in sequence; wherein:

[0022] The metal foil layer 3 includes a plurality of metal grids and a plurality of metal markers. The plurality of metal grids are formed by the intersection of a plurality of longitudinal metal lines and a plurality of transverse metal lines. Each of the metal grids has a through hole. The metal markers are used to identify the position of each through hole. The metal foil layer 3 is used for imaging under X-rays to locate each through hole.

[0023] like Figure 4a As shown, the silk-screen layer includes a plurality of color-developing grids and color-developing marks. The color-developing grids overlap with the metal grids, and the display marks overlap with the metal marks. The silk-screen layer can display color under non-X-ray conditions to locate each of the through holes.

[0024] It is understood that because the metal foil layer includes multiple metal grids, each of which is formed by intersecting and cutting horizontal and vertical metal lines, and each metal grid is arranged in an array, the metal grid is a rectangular grid, for example, a square grid. If the through-holes are circular, the through-holes can be larger in diameter within the square grid than within the rectangular grid. Because the metal grid is made of metal, it can be observed under X-rays.

[0025] It is understandable that each through hole in the metal grid is marked with a metal marker, so that each through hole can be distinguished. Since the metal marker is also made of metal, the metal marker corresponding to each through hole can be observed under x-ray.

[0026] It is understandable that the metal foil layer is arranged below the polymer film layer, and the silk screen layer is arranged above the polymer film layer. The reason for setting the silk screen layer is that the polymer film layer may be made of a transparent material or a non-transparent material. When the polymer film layer is made of a non-transparent material, the metal foil layer below the polymer film layer will be covered, and the individual metal grids and metal logos cannot be observed with the naked eye under non-x-ray conditions. In order to observe each metal grid and metal logo under non-x-ray conditions, a silk screen layer that is identical to and overlaps with the metal thin layer is set, so that the metal grids and metal logos can be seen through the silk screen layer under non-x-ray conditions.

[0027] It is understandable that the polymer film layer is the carrier of the adhesive layer, metal foil layer, silk screen layer and other layers except the rectangular release paper.Figures 1a to 1b As shown, the rectangular release paper is on the back side, and the screen printing layer is on the front side. The rectangular release paper needs to be torn off during use. After tearing off the rectangular release paper, layers such as the adhesive layer, the metal foil layer, and the screen printing layer are all on the polymer film. The polymer film layer carrying each layer is attached to the skin surface of the part where surgery needs to be performed. When irradiating the skin of this part with X-rays, since the metal foil can be imaged under X-rays, the metal grid and the metal markings can be seen under X-rays. In this way, medical staff can find the most suitable position for surgical entry in the X-ray imaging diagram, and determine the metal markings corresponding to this position. Then, use a medical marker pen to pass through the through holes and make corresponding marks on the skin. Finally, tear off the polymer film layer carrying each layer and start the surgery.

[0028] It can be understood that when medical staff use a medical marker pen to pass through the through holes and mark on the skin, it is not carried out under X-rays. Therefore, the screen printing layer is needed. The shape, position, layout, and size of the screen printing layer and the metal foil layer are the same, only the materials of the two are different. The metal foil layer is imaged under X-rays, which is convenient for medical staff to determine the metal markings at the position when finding the suitable position for surgery under X-rays. Since the metal foil layer may not be visible to the naked eye under non-X-rays. For example, the polymer film layer is opaque, and since the metal foil layer is located under the polymer film layer, the metal foil layer is not visible under non-X-rays. Therefore, under non-X-rays, it is necessary to make marks on the skin according to the previously determined metal markings and the positions of the through holes marked on the screen printing layer.

[0029] As Figure 2a 、 2c shown, stick the X-ray positioning patch on the skin. Under X-rays, the imaging as shown in Figure 2b can be seen. The metal grid and the metal markings can be seen in Figure 2b .

[0030] It can be understood that the function of the through holes is to facilitate medical staff to make position marks on the skin before surgery. After marking, it is necessary to tear off the polymer film layer carrying each layer, otherwise there may be a risk that substances or fragments on the positioning patch enter the biological tissue during surgery.

[0031] It can be understood that the X-ray positioning patch can be directly stuck on the skin, or stuck on a certain material that has been applied to the surgical site, such as a surgical drape.

[0032] It can be understood that since X-rays are used in both X-ray and CT detection scenarios, the X-ray positioning patch provided by the present invention can be applied to the above two scenarios.

[0033] Among them, the polymer thin film layer will not be imaged under X-ray imaging to avoid interfering with the imaging of the metal foil layer. The polymer thin film layer can be made of PVC (i.e., polyvinyl chloride), PE (i.e., polyethylene), polyimide, polyester materials, etc., and the thickness can be set as required. For example, the thickness is set in the range of 0.08 mm to 0.5 mm.

[0034] Among them, the function of the adhesive layer is to attach the polymer thin film layer carrying the metal foil, silk screen layer, etc. to the skin or surgical towel. The adhesive can use a medical adhesive that meets biocompatibility requirements, and the thickness can be set as required. For example, the thickness is in the range of 0.05 mm to 0.2 mm.

[0035] Among them, the metal foil layer can use various metal materials that can be imaged under X-ray, such as lead, copper, iron, stainless steel, alloy, gold, etc., and the thickness can be set as required. For example, the thickness is in the range of 0.035 mm to 0.5 mm.

[0036] Among them, the number of metal grids in the metal foil layer can be determined according to the size of the positioning sticker. For example, the metal grids can have 3 to 30 rows and 3 to 30 columns. Since a rectangular release paper is used in the present invention, such as a square rectangular release paper, in this case, the number of rows and columns of the metal grids can be the same.

[0037] Among them, the silk screen layer can be made of a certain paint, ink and other pigments that can show colors.

[0038] In specific implementation, in order to facilitate tearing off the rectangular release paper, a release paper easy tear opening can be provided on the rectangular release paper. For example, as Figure 1c shown, the rectangular release paper can be very conveniently torn off through this release paper easy tear opening.

[0039] In specific implementation, the above metal markings can include longitudinal metal markings and transverse metal markings for each metal grid. The types of the transverse metal markings and the longitudinal metal markings are different, and the types include numbers, letters, characters and / or image symbols.

[0040] That is to say, longitudinal metal markings and transverse metal markings are set. In order to facilitate the distinction between the transverse metal markings and the longitudinal metal markings, the transverse metal markings and the longitudinal metal markings adopt different types. The types specifically include numbers, letters, characters and / or image symbols. Among them, the numbers can include Arabic numerals (1, 2, 3...), Chinese numerals (one, two, three...), Roman numerals, etc., and the letters can include capital English letters, lowercase English letters, etc.

[0041] For example, in Figure 4a , the transverse metal markings are capital English letters: A, B, C, D, E, and the longitudinal metal markings are Arabic numerals 1 to 15.

[0042] In addition, to ensure clear identification under X-rays, the metal markings cannot be too small. For example, the height of the metal markings can be set within the range of 3 mm to 9 mm.

[0043] In specific implementation, the widths of the horizontal metal line and the vertical metal line can be the same and can be set as required. To ensure clear identification under X-rays, the width cannot be too small. For example, the width can be set within the range of 0.3 mm to 1.2 mm.

[0044] In specific implementation, if the metal foil layer is relatively thin, the imaging effect under X-rays is not good. To improve the imaging effect of the metal grid and the metal markings under X-rays and enable clearer identification, as Figure 3b shown, a second metal foil layer can be further provided. To distinguish the two metal foil layers, the metal foil layer mentioned above can be called the first metal foil layer. In this way, the metal grid in the first metal foil layer is the first metal grid, and the metal marking in the first metal foil layer is the first metal marking. A second metal foil layer 5 is provided above the polymer thin film layer. That is to say, the rectangular positioning sticker body can further include a second metal foil layer 5 disposed between the polymer thin film layer and the silk screen layer. The second metal foil layer 5 includes a second metal grid and a second metal marking. The second metal grid is the same as and coincides with the first metal grid, and the second metal marking is the same as and coincides with the first metal marking.

[0045] That is to say, the positions, shapes, sizes, and layouts of the second metal foil layer and the first metal foil layer are the same. The difference is their installation positions. The first metal foil layer is disposed below the polymer thin film layer, and the second metal foil layer is disposed above the polymer thin film layer.

[0046] Due to the provision of two metal foil layers, the thickness of the metal foil layer is greatly increased, which can greatly improve the imaging effect of the metal foil layer under X-rays and clearly identify each metal grid and metal marking.

[0047] In specific implementation, to further position the through holes, the metal foil layer can further include cross metal lines disposed within each metal grid. The intersection point of the extension lines of the cross metal lines is the center of the corresponding through hole.

[0048] As Figure 4aAs shown, the cross-shaped metal line is actually four metal lines. Each line leads from the midpoint of one side of the metal grid to the through-hole. The extension lines of the two metal lines on the opposite sides coincide, and the extension lines of the two metal lines on the side edges intersect perpendicularly, and the perpendicular intersection point is located at the center of the through-hole. Therefore, in practice, the center of the through-hole can be determined according to the intersection point of the extension lines of the cross-shaped metal line, so as to realize the positioning of the center of the through-hole, and accurate marking can be carried out in the through-hole.

[0049] Among them, the width of the cross-shaped metal line can be slightly smaller than the widths of the longitudinal and transverse metal lines of the metal grid.

[0050] In practice, it is possible that the position that needs to be marked on the skin does not appear inside the through-hole, but in other areas outside the through-hole. In order to reduce the occurrence of this situation, it is necessary to further increase the coverage rate of the through-hole, so more through-holes can be set. To distinguish from the above-mentioned through-holes, the through-holes in the above text are called the first through-holes here. Figure 4a It can be seen from the figure that the sizes of the first through-holes are the same. Figure 4b As shown, the metal foil layer may further include a plurality of second through-holes. The size of the second through-hole is smaller than the size of the first through-hole, and the center of the second through-hole is located at the intersection of the longitudinal metal line and the transverse metal line.

[0051] It can be understood that the size of the second through-hole is relatively small. If the metal markings corresponding to the second through-hole are set between two adjacent metal markings of the first through-hole, the size of the metal markings of the second through-hole will be relatively small, so the imaging effect under X-ray is not good. Therefore, in the present invention, no corresponding metal markings are set for the second through-hole, but the metal markings of the first through-hole are used to identify and position the second through-hole. For example, in Figure 4b, the transverse metal markings A and B are used to represent the second through-holes located between two corresponding columns of the first through-holes, and the longitudinal metal markings 1 and 2 are used to represent the second through-holes between two corresponding rows of the first through-holes.

[0052] In specific implementation, the sizes of the metal grid, the first through-hole and the second through-hole can be set according to needs. For example, the size of the metal grid can be 10mm X 10mm. At this time, the diameter of the first through-hole can be in the range of 3mm to 8mm, and the diameter of the second through-hole can be in the range of 2mm to 6mm.

[0053] In specific implementation, the thickness of each layer can be set according to needs. For example, the thickness of the adhesive can be in the range of 0.05mm to 0.2mm, the thickness of the polymer film can be in the range of 0.08mm to 0.5mm, and the thickness of the metal foil layer can be in the range of 0.035mm to 0.5mm.

[0054] In specific implementation, there are various processing methods for the metal foil layer, such as forging and rolling method, electrolysis method, etching method, etc. The fixation between the metal foil layer and the polymer thin film layer can be achieved by bonding or hot pressing. When using the bonding method for fixation, the adhesive that can be used is acrylic adhesive. That is to say, at this time, the rectangular positioning sticker body may further include an adhesive layer disposed between the metal foil layer and the polymer thin film layer, and the adhesive layer is used to bond the metal foil layer and the polymer thin film layer.

[0055] In specific implementation, the processing technology of the X-ray positioning sticker can also use the processing technology of flexible PCB.

[0056] It can be understood that the X-ray positioning sticker provided by the present invention can be applied not only to the human body but also to the animal body for preoperative positioning of non-open surgeries, such as puncture, biopsy, endoscopic surgery, spinal surgery, lumbar disc surgery, etc., and the application range is very wide.

[0057] The X-ray positioning sticker provided by the present invention includes a rectangular positioning sticker body and a through hole, and the rectangular positioning sticker body includes a rectangular release paper, an adhesive layer, a metal foil layer, a polymer thin film layer, and a silk screen layer. When using the positioning sticker, just tear off the rectangular release paper. It can be seen that the rectangular release paper plays a protective role before use; the adhesive layer can stick the polymer thin film layer carrying the metal foil layer and the silk screen layer on the skin, etc. The metal foil film layer includes a metal grid and a metal mark, and the metal grid and the metal mark can be imaged under X-rays. In order to be able to visually distinguish each metal grid and metal mark with the naked eye under non-X-rays, a silk screen layer identical and coincident with the metal foil layer is provided. In this way, it is convenient for medical staff to mark by passing through the corresponding through hole under non-X-rays according to the metal mark determined under X-rays, and preoperative positioning can be carried out very accurately, improving the positioning accuracy. Moreover, the use of the X-ray positioning sticker is very simple, and rapid positioning can be achieved, improving the positioning efficiency.

[0058] The above-mentioned specific implementation manners have further detailed the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above-mentioned is only the specific implementation manners of the present invention and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made on the basis of the technical solution of the present invention should be included in the protection scope of the present invention.
