Abstract
Description
Technical Field
[0001] The utility model relates to an ultrasound-guided positioning sticker. Background Art
[0002] Breast nodules are a common disease in women. For patients with breast nodules without obvious contraindications, surgical resection is currently recommended because the benefits of surgery are relatively high. For patients with larger breast nodules and thinner bodies, surgeons can accurately locate them through palpation. However, for smaller, deeper breast nodules and patients with fatter bodies and thicker glands or fat layers, surgeons often cannot accurately touch the location of the nodules. Although the standard ultrasound report will describe the location of the breast nodules in detail (positioned by the clock method and the distance from the nipple), its positioning is still vague and has a certain degree of operator subjectivity (such as positioning in the clock direction). For breast nodules that cannot be touched, accurate preoperative positioning can help reduce the surgical incision, shorten the surgical search time, and reduce postoperative complications.
[0003] The existing commercial breast nodule localization needles are used by ultrasound doctors to insert a puncture needle with a barb (to prevent slipping) into the breast nodule under the guidance of the image before the operation. During the operation, the surgeon finds the lesion along the guide wire exposed outside the skin. However, this method requires aseptic operation, is complicated and time-consuming, and is an invasive operation that causes some pain to the patient. Therefore, it is less accepted by the surgical and ultrasound departments and is less clinically used. Surgeons prefer ultrasound doctors to mark the surface of the breast nodules before the operation.
[0004] Ultrasound positioning of breast nodules is to mark the observed nodule position through the cross method after the breast nodule is observed by ultrasound. In actual operation, after the nodule is observed, the ultrasound probe remains stationary, and then a mark is made in front and on the side of the probe. The intersection of the two marked lines is the positioning point. The current manual operation is often rough and simple; and the operation is troublesome:
[0005] First, the ultrasound probe is a long strip. The markings on the front are generally more accurate. However, because the side is very wide, the markings on the side are roughly estimated based on the position of the nodule on the image. Therefore, it is difficult to accurately locate it at one time. It is often necessary to observe and adjust after marking, and repeat this process several times to accurately locate it.
[0006] Second, ultrasound examination requires the application of coupling agent on the skin surface. Coupling agent is a transparent gel-like substance, which makes it easy for the marker pen to not release liquid when marking, or the pen tip is stained with coupling agent, resulting in unclear markings. In addition, the ultrasound repeatedly adjusts the position, which also means that there is always coupling agent on the skin surface, which is not easy to wipe off. In addition, when the patient wipes after the examination, the mark is also easy to erase. Utility Model Content
[0007] The present invention provides an ultrasound-guided positioning sticker to solve the problem in the prior art that it is inconvenient to accurately position a mark after an ultrasound probe finds a nodule.
[0008] In order to achieve the above-mentioned purpose, the scheme of the present invention is: an ultrasound-guided positioning sticker, characterized in that: it includes a transparent film layer and a release layer; the inner surface of the transparent film layer is provided with a sound-transmitting central area and an adhesive peripheral area; the sound-transmitting central area is rectangular and is used to fit with the ultrasound probe; a longitudinal positioning line is provided on the center line of the long side of the sound-transmitting central area and a transverse positioning belt is provided on the center line of its wide side; the transverse positioning belt contains a sound-impermeable material; the release layer is provided with a hollow central area; the hollow central area matches the shape of the sound-transmitting central area; the inner surface of the release layer and the inner surface of the transparent film layer are bonded together through the adhesive peripheral area.
[0009] With the above scheme, when in use, the ultrasound-guided positioning sticker is wrapped around the ultrasound probe, and the rectangular sound-transmitting central area is in contact with the bottom surface of the rectangular ultrasound probe; the sound-transmitting central area can transmit ultrasound waves without affecting the imaging and scanning of the probe; and the transverse positioning band is not transparent to ultrasound waves and is displayed as an unimaging area on the image. At this time, by slightly moving the probe, the nodule is placed in the unimaging area, which indicates accurate positioning; then, after wiping the skin around the ultrasound probe clean, pinch and tear off the release layer, and the transparent film layer can be pasted on the skin, and the intersection of its longitudinal positioning line and the transverse positioning band is the projection point of the nodule on the body surface to achieve accurate position marking; in this way, the position of the breast nodule can be accurately located and marked through simple steps. In addition, the size and depth of the nodule can also be recorded on the transparent film layer.
[0010] Therefore, the above technical solution can solve the problem in the prior art that it is inconvenient to accurately locate the mark after the ultrasound probe finds the nodule.
[0011] The above technical solution is thin, simple, and low-cost. It can slide with the probe during ultrasound examination. After the probe determines the location of the nodule, it can be marked directly below the probe without removing the probe. There is no need to repeatedly confirm the position accuracy, and it is not affected by the ultrasonic coupling agent. Because the transparent film layer is firmly attached to the nodule position and marked at the intersection of its longitudinal positioning line and the transverse positioning band, it is not easy to fall off and the display is clear. In addition, compared with the existing positioning guide wire method, this technical solution is non-invasive marking, simple to operate, and easier to use in clinical operations.
[0012] Furthermore, the width of the longitudinal positioning line is 0.5-1.2 mm; the width of the transverse positioning band is 2.5-4 mm.
[0013] Furthermore, a label area is arranged on the transparent film layer at the pasting peripheral area.
[0014] Furthermore, the outer surface of the transparent film layer is a smooth surface; the sound-transmitting central area is a smooth surface; and the inner surface and the outer surface of the release layer are both smooth surfaces.
[0015] Furthermore, a protrusion is arranged on the edge of the release layer.
[0016] Furthermore, the protrusion is in a strip shape and has a size of 1×0.5 cm.
[0017] Furthermore, a guide line is provided on the release layer between the protrusion and the hollow central area.
[0018] Furthermore, the overall shape of the ultrasound-guided positioning sticker is elliptical.
[0019] Beneficial effects of the utility model:
[0020] First, the utility model can be used for accurate positioning and marking of breast nodules (or other nodules) during ultrasonic detection, and has the advantages of simple operation, low cost, and great practicality;
[0021] Second, the utility model can slide along with the probe during the ultrasonic examination, and after the probe determines the position of the nodule, it is not necessary to remove the probe to mark it directly below the probe in one step, and it is not necessary to repeatedly confirm the position accuracy, and it is not affected by the ultrasonic coupling agent; because the transparent film layer is firmly attached to the nodule position and marks the intersection of its longitudinal positioning line and the transverse positioning belt, it is not easy to fall off and the display is clear;
[0022] Third, compared with the existing positioning guide wire method, the utility model is non-invasive, easy to operate, and easier to use in clinical operations;
[0023] Fourth, the utility model provides a protrusion on the edge of the release layer, and a guide line is provided between the protrusion and the hollow central area; in this way, when the probe is positioned, the protrusion can be pinched by hand to tear the release layer along the guide line and tear it off, and the transparent film layer can be attached to the skin. Therefore, it is more convenient to tear and separate the release layer and the transparent film layer, the direction is smooth, and the operation is simpler. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments:
[0028] Example 1: See Figure 1-3 , an ultrasound guided positioning sticker, comprising a transparent film layer 1 and a release layer 2; the transparent film layer 1 is made of transparent material.
[0029] In this embodiment, the overall shape of the ultrasound-guided positioning sticker is elliptical.
[0030] The transparent film layer 1 has a sound-transmitting central area a1 at the center of its inner surface, and the rest is a bonding peripheral area b1.
[0031] The sound-transparent central area a1 is arranged at the center of the transparent film layer 1; the sound-transparent central area a1 is rectangular and is used to fit with the rectangular bottom surface of the ultrasonic probe; the sound-transparent central area a1 is made of a material that can transmit ultrasonic waves, such as polytetrafluoroethylene or other known materials, that is, the ultrasonic waves generated by the ultrasonic probe can pass through the sound-transparent central area a1.
[0032] In addition, a longitudinal positioning line c is provided on the center line of the long side (i.e., the long axis) of the sound-transmitting central area a1, and a transverse positioning band d is provided on the center line of its wide side (i.e., the short axis); the transverse positioning band d contains a sound-impermeable material, such as lead powder or other known materials; that is, the ultrasonic wave generated by the ultrasonic probe cannot penetrate the transverse positioning band d.
[0033] In this embodiment, the longitudinal positioning line c is 1 mm wide and is a thin line; the transverse positioning band d is 3 mm wide and is a wide band. By utilizing the ultrasound-impermeable property of the transverse positioning band d, after a nodule is found, the nodule is placed in the ultrasound-impermeable dark area generated by the transverse positioning band d to achieve accurate positioning.
[0034] The surface of the adhesive peripheral area b1 has adhesive material for bonding with the inner surface of the release layer 2 .
[0035] The release layer 2 is provided with a hollow central area a2 and a remaining bonding peripheral area b2;
[0036] The hollow central area a2 matches the outer shape of the sound-transmitting central area a1. Specifically, the hollow central area (a2) is a hollow hole that matches the outer shape of the sound-transmitting central area a1. The bonding peripheral area b2 matches the outer shape of the bonding peripheral area b1.
[0037] The inner surface of the release layer 2 and the inner surface of the transparent film layer 1 are bonded together through the bonding peripheral area b1. That is, the bonding peripheral area b2 of the inner surface of the release layer 2 and the bonding peripheral area b1 of the inner surface of the transparent film layer 1 are bonded together and can be separated from each other after being torn apart.
[0038] In this embodiment, the outer surface of the transparent film layer 1 is smooth; the sound-transmitting central area a1 of the inner surface of the transparent film layer 1 is smooth; and the adhesive peripheral area b1 of the inner surface of the transparent film layer 1 is an adhesive surface. The inner and outer surfaces of the release layer 2 are both smooth.
[0039] In this embodiment, when in use, the ultrasound-guided positioning sticker is wrapped around the ultrasound probe, and the sound-transparent central area a1 is attached to the ultrasound probe; the sound-transparent central area a1 can transmit ultrasound without affecting the imaging and scanning of the probe; and the transverse positioning band d is not transparent to ultrasound and is displayed as an unimaging area on the image. At this time, by slightly moving the probe, the nodule is placed in the unimaging area, which means that the positioning is accurate; then, after wiping the skin around the ultrasound probe clean, pinch and tear off the release layer 2, and the transparent film layer 1 can be pasted on the skin, and the intersection of its longitudinal positioning line c and the transverse positioning band d is the projection point of the nodule on the body surface to achieve accurate position marking; in this way, the position of the breast nodule can be accurately located and marked through simple steps. In addition, the size and depth of the nodule can also be recorded on the transparent film layer 1.
[0040] Therefore, this embodiment can solve the problem in the prior art that it is inconvenient to accurately locate the mark after the ultrasound probe finds the nodule.
[0041] The above embodiment is thin, simple, and low-cost. It can slide with the probe during ultrasound examination. After the probe determines the location of the nodule, it can mark the area directly below the probe without removing the probe. There is no need to repeatedly confirm the position accuracy, and it is not affected by the ultrasonic coupling agent. Since the transparent film layer is firmly attached to the nodule position and marked at the intersection of its longitudinal positioning line and the transverse positioning band, it is not easy to fall off and the display is clear. In addition, compared with the existing positioning guide wire method, the present invention is non-invasive marking, simple to operate, and easier to use in clinical operations.
[0042] Example 2: See Figure 1-3 Based on the first embodiment, the following improvements are made:
[0043] In addition, a label area e is provided on the transparent film layer 1 at the adhesive peripheral area b1. After the nodule is located, the size of the located nodule and its depth from the body surface are recorded on the label area e, which is convenient for surgeons to find the nodule and understand the patient's information in more detail.
[0044] In addition, a protrusion f is provided on the edge of the release layer 2. Since the protrusion f is only connected to the release layer 2, it is used to distinguish the transparent film layer 1 from the release layer 2, and it is also convenient to pinch the protrusion f to easily tear off the bottom release layer 2 separately. Specifically, the protrusion f is strip-shaped and has a size of 1×0.5 cm.
[0045] Furthermore, a guide line g is provided on the release layer 2 between the protrusion f and the hollow central area a2. In this way, when the probe is positioned, the release layer 2 can be torn off along the guide line g by pinching the protrusion f, and the transparent film layer 1 can be attached to the skin. Therefore, the release layer 2 can be torn off from the transparent film layer 1 more conveniently, the direction is smooth, and the operation is simpler.
[0046] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
