Description

Mammary gland focus positioning plaster

Technical Field

The invention relates to a human tissue body surface positioning device, in particular to a tool for assisting ultrasonic positioning of breast lesion.

Background

Breast nodules are a common clinical symptom. Pathological biopsy is an important method for definitive diagnosis. Accurate localization is critical for effective pathological diagnosis. Fibroadenoma frequently occurs in benign nodules, and the condition that postoperative scars influence breast attractiveness can be avoided by selecting a proper incision before an operation and performing minimally invasive treatment.

At present, the positioning of the breast lesion at home and abroad is mainly completed under the guidance of ultrasound, but the positioning method has some defects. The development of the hardware of the ultrasonic instrument greatly improves the sensitivity and specificity. However, the breasts are soft tissue organs, and because of the existence of the gap behind the breasts, the breasts can move up and down, left and right on the body surface, and the shape change of lying and sitting is also large.

Most commonly, ultrasonic guided marker body surface markings are used. The method is simple, but the positioning is not accurate enough and is easy to lose. The main reason is that under the medical ultrasonic coupling agent, the mark handwriting is difficult to display; the handwriting of the patient can be easily wiped off if the patient wears the clothes after bathing, and the retention time is short. Another approach is ultrasound guided guidewire localization biopsy. The method is to place a mammary gland positioning needle at the edge or the inner part of a lesion by using a puncture guide frame under anesthesia, and then release and fix a guide wire preset in the positioning needle at the lesion. Although the method is accurate in positioning, the technology is complex, needs to be operated by multiple people, and is long in time consumption and traumatic.

Therefore, the research and development of a tool for assisting the ultrasonic positioning of the breast focus positioning, which is simple, convenient and practical to use, has important significance.

SUMMERY OF THE UTILITY MODEL

The not enough to prior art, the utility model discloses a solve the problem of body surface projection location before the mammary gland focus art, research and develop an auxiliary ultrasonic wave location mammary gland focus location subsides. The positioning patch is simple and practical, is convenient to use, and can be used for positioning and pasting the breast focus on the surface of the skin by utilizing the principle of metal probe ultrasonic projection, and positioning the focus more accurately through the positions of the two metal probes.

The technical scheme of the utility model is that:

the utility model provides a mammary gland focus location subsides, includes that the front is equipped with the first zona pellucida of pasting the layer, the zona pellucida is equipped with scale zone and blank area, the scale zone is located between two adjacent blank areas, be equipped with two piece at least metal probes along the scale mark direction on the scale zone.

Two ends of the metal probe respectively extend out of two side edges of the transparent belt by 0.2-0.3 cm. The structural design is that when the breast focus is fixed on the surface of the ultrasonic probe in a positioning way, the parts extending out of the two ends can be bent to clamp the two side walls of the ultrasonic probe, so that the fixation is firmer.

The number of the metal probes is preferably two. Generally, two probes can well locate the focus.

But does not exclude the scheme of setting a plurality of probes in the calibration area, for example, every 1cm is provided with a metal probe (the distance can be smaller, but is not practical, the metal probe and the transparent belt are detachably connected, when the width of the focus to be positioned is larger than 1-2cm, the middle 1 probe is removed for use, when the width of the focus to be positioned is larger than 2-3cm, the middle 2 probes are removed for use, when the width of the focus to be positioned is larger than 3-4cm, the middle 3 probes are removed for use, when the width of the focus to be positioned is larger than 4cm, the positioning is basically not needed, and the position of the focus can be obtained by touching with hands.

Preferably, the distance between two adjacent metal probes can be set to be 1cm, 2cm or 3cm, without excluding other distance schemes.

Preferably, a second adhesive layer is arranged on the back of the blank area. The breast focus positioning patch is convenient to be inversely pasted on the surface of the skin of a human body.

Preferably, the first pasting layer and the second pasting layer are externally provided with a protective film layer, so that the pasting layer is protected from dust and losing viscosity.

Preferably, be equipped with easily tearing the line in the blank region, be convenient for tear a working section, a working section is two blank regions and is located the scale district between two blank regions.

Preferably, the metal probe comprises a probe made of iron, lead, silver, aluminum and other materials.

In a preferable scheme, the width of the breast lesion positioning paste is 1.3-1.5cm, and the length of the scale area is 4-6 cm.

Preferably, the width of the metal probe is 0.01mm-0.1 mm.

Preferably, the back surfaces of the blank area and the scale area are provided with couplant layers. The thickness of the couplant layer is smaller than 1cm, and the couplant layer has a new advantage, so that the ultrasound can display sound shadow through the couplant layer, and a doctor does not need to additionally smear the couplant on the patient during operation. The couplant layer is a structure with the inside filled with the couplant completely, the outer surface of the couplant layer is wrapped by a layer of film, one side surface of the couplant layer is connected with the back surfaces of the blank area and the scale area, and the other side of the couplant layer is in contact with the skin of a patient when the couplant layer is used.

The invention will be further explained and illustrated below:

the principle of the breast focus positioning paste of the utility model is that the metal probe can generate the sound shadow perpendicular to the skin of the breast when the ultrasonic probe is scanned. When the focus is scanned by ultrasound, the distance between the two probes is used to wrap the focus in the sound shadow, so as to estimate the width of the focus on the body surface. The body surface projection of the focus can also be realized by fixing the mammary gland positioning patch on the surface of the skin. The fixed positioning paste is not easy to erase due to the reinforcement of the transparent adhesive tape. In addition, because the body surface of the focus can be pressurized, the skin at the position of the metal probe can have indentation, and the incision position can be conveniently determined by an operation. The operation process only needs one sonographer, is simple and easy to learn, and the whole process is completed noninvasively when the ultrasonic examination is completed. The positioning working efficiency is improved, and the positioning accuracy is improved. Furthermore, the metal probe is developed on the molybdenum target. If the focus is found by the patient through ultrasound, molybdenum target verification is needed, and the method can also be finished after the breast focus is fixed. This ensures that the lesions observed are the same lesion. The ruler on the location sticker can help the surgeon to estimate the size of the lesion and thus select the appropriate size of the surgical incision.

The using method comprises the following steps: as shown in fig. 5 and fig. 6, the back surface of the breast lesion positioning paste is pasted on the surface of the ultrasonic probe, and the transparent belt is very thin (similar to the thickness of the conventional transparent adhesive, even thinner), so that the breast lesion positioning paste has no influence on the ultrasound. The two metal probes are used for generating a smooth sound shadow vertical to the mammary gland skin when an ultrasonic probe is used for scanning, and the sound shadow of the two probes is used for wrapping the focus in the sound shadow, so that the width of the focus on the body surface is estimated. After the breast lesion locating paste is manufactured, the breast lesion locating paste is torn off from the surface of the ultrasonic probe and is inversely pasted at the position of the breast to be located, namely the position of the indentation of the probe on the skin surface due to pressing. Therefore, the positioning is accurate, and the phenomenon that the positioning position cannot be found or the positioning deviation is avoided due to the change of the shape of the breast.

If the scheme that the protective films are arranged outside the first pasting layer and the second pasting layer, the protective films are torn off before use, which is a conventional technical means and is not explained and illustrated too much.

Compared with the prior art, the utility model has the advantages that:

the positioning paste is simple and practical, is convenient to use, utilizes the principle of ultrasonic sound and shadow artifacts of the metal probes, generates sound and shadow at the rear part during ultrasonic examination through the two metal probes, and can surround a focus, thereby positioning the focus on the body surface.

The utility model discloses can not have the swift location mammary gland focus of wound, the more accurate body surface position that shows the focus. The markers are not easily lost by human factors and facilitate the surgeon in selecting the appropriate surgical incision and another imaging method for verification.
