Description

  The present invention relates to a brassiere, and more particularly to a breast cancer biopsy subject that wears and protrudes to squeeze the breast forward, and even when the breast is small, the needle for cell aspiration from the side to the target position inside the breast It is possible to suck cells by inserting them easily.

As a method for diagnosing breast diseases such as breast cancer, visual palpation, which has been widely used in the past, is a method in which the breast is touched by hand and the found lesion is removed by incision surgery. There was a problem in that it was not possible to find a small early cancer.
In addition, in order to focus on visual inspection, the location of the incision and the cells to be extracted may be mistaken. In addition, if the incision is performed, suturing is required regardless of whether the cells are benign or malignant. It was a burden.

Therefore, recently, mammotom biopsy using mammography and ultrasound has attracted attention. This mammotome biopsy is a method of sucking cells by inserting a thin needle (probe) for cell suction into the breast while confirming the inside of the living body by mammography or ultrasonic images.
According to this mammotom biopsy, it is possible to accurately collect the lesion without removing the lesion position and without damaging the breast. In particular, it is difficult to find a lump smaller than 5 mm by diagnosis using an ultrasonic image, but emphasis is placed on mammography that can be found even by a very small lump of about 2 to 3 mm.

As shown in FIGS. 6 and 7, the mammotome biopsy device 1 sandwiches the breast from various directions, such as up and down, left and right, and diagonally, with a table 2 on which a film is placed and a transparent plastic plate 3, and presses it flatly. X-rays are taken, and the X-ray image is viewed to confirm the position of the lesion, and the needle 4 is inserted into the flatly pressed breast to collect cells.
At that time, if the compressed breast does not have the thickness necessary for sample collection, there is a problem that the needle penetrates and cell collection is impossible. The thickness required for sampling is usually 3 centimeters or more, and in the case of a small breast that is insufficient for this thickness, the breast meat is gathered together by hand to ensure the thickness. It returned to this state, and it was impossible to collect it because it could not maintain a thickness of 3 cm or more.

There has not been provided a brassiere that adjusts the breast so that the breast protrudes forward so that the breast is exposed and the needle can be inserted during the mammotome biopsy.
Conventionally, brassieres that can expose breasts are provided for breastfeeding and the like.
For example, as shown in FIG. 10, the brassiere 5 disclosed in Japanese Utility Model Laid-Open No. 52-29523 (Patent Document 1) has a left and right cup portion 5a as a half cup shape provided with a notch portion 5b in the upper half portion. Yes. As shown in FIG. 11, the brassiere 6 disclosed in Japanese Patent Laid-Open No. 2001-254206 (Patent Document 2) is provided with an opening 6b at the center of the left and right cup portions 6a, and the tip of the wearer's breast Can project from the opening 6b.

  The brassiere 5 and the brassiere 6 are merely configured to expose the nipple portion or the circumference of the nipple, and do not collect and hold breast meat to increase the volume.

Japanese Utility Model Publication No. 52-29523 JP 2001-254206 A

  The present invention has been made in view of the above problems, and mainly provides a brassiere that can increase the volume of a small breast and maintain that state in order to enable mammography biopsy using mammography even with a small breast. Is an issue.

In order to solve the above problems, the present invention is a brassiere that does not have a cup part that covers the left and right breasts, and that squeezes the meat of the breast forward so that the circumference of the cup part positioned on the outer ring of the breast can be reduced,
At the front center part between the left and right breasts, the lower base part and the side part, a cup part peripheral edge is formed along the outer ring excluding the upper edge of the breast. The first tension band is connected, the second tension band is connected to the side ends, and the left and right first tension bands are expanded and contracted after passing the left and right first tension bands through the left and right rings, respectively. And the left and right second tension bands are passed through the left and right rings respectively and then connected to the back cloth to form left and right shoulder straps, and the size between the left and right first tension bands is reduced by the expansion and contraction means. through the upper cut ring provides a brassiere characterized in that it the second tension zone tension before the center side, and configured to reduce the diameter of the cup portion peripheral edge by.

  In the brassiere constructed as described above, the left and right first tension bands are pulled together while the left and right second tension bands are sufficiently pulled, so that the side portions connected to the second tension band are drawn toward the center side. And the first and second tension bands located near the upper edge of the breast are pushed down, so that the circumference of the cup part is reduced in diameter overall, and the breast surrounded by the outer ring is pushed forward. The state can be maintained. Therefore, even if the breast is small in volume, wearing the brassiere keeps the whole breast, and moreover the meat collected from the top and sides of the breast effectively concentrated in the center of the breast and maintained in a volume-up state. Therefore, it is possible to secure the thickness necessary for sampling of the mammotom biopsy during the examination time.

A core material-enclosed cloth in which a second core material made of a wire or a resin bone is enclosed is attached to the side periphery of the left and right cup parts, and the upper end of the core material-enclosed cloth is sewn to the second tension band. It is preferable.
Thus, by arranging the second core material along the side edge of the breast and sewing the core material-encapsulating cloth enclosing the second core material with the second tensile belt, the second tensile belt is brought inward. The second core material deforms in the direction of diameter reduction while holding the outer ring on the side of the breast when attracted, so that the breast meat does not escape to the side and remains within the cup periphery for a long time. Can do.

Furthermore, a core material enclosing cloth enclosing a first core material made of a wire or a resin bone extending from the front center periphery of the left and right cup periphery to the position in contact with the second core material is attached, and the core material is enclosed The upper end of the fabric may be sewn to the first tension band.
As described above, when the first core material is disposed from the front center side edge to the lower end of the breast, and the core material-enclosed cloth enclosing the first core material is sewn to the first tension band, the first tension band is changed to the second tension band. When pulling in the reduced diameter direction together with the tension band, the breast deforms in the reduced diameter direction while holding the peripheral edge on the front center side of the breast, so that the breast meat does not escape to the front center side and is kept in the cup periphery. it can.
In addition, a first core material that extends the core material from the front center side of the breast outer ring to a side position of the lower edge, and a second core material that extends continuously to the side upper edge of the first core material; When divided, when the tension in the diameter reducing direction acts on the first and second core members, the first core member is positioned so as not to deviate from the lower outer ring of the breast, and the second core is positioned from the side outer ring of the breast. The material can be positioned so as not to be displaced, and the diameter of the breast can be reduced while gathering the breasts forward, so that only the core material can be lifted from the outer ring of the breast and not reduced in diameter. In addition, since the breast outer ring is kept pressed even after the diameter reduction, the necessary breast volume can be maintained during the examination time.

The extension means between the left and right first tension bands connects the tip annular portion of either the left or right first tension band through the first retaining ring, and the left or right first tension band is the second retaining band. It is preferable that after passing through the ring, it is folded back through the first stop ring, the tip annular portion is connected through the second stop ring, and the position of the second stop ring is moved to expand and contract.
With the so-called turnbuckle configuration described above, the contraction and extension can be easily performed by simply pulling either the left or right piece of the second ring.

The front center portion is formed of a non-stretchable cloth, and the side portions are formed of a stretchable cloth.
Since the front center portion is located on the front center side with a small amount of deformation when the diameter of the periphery of the cup portion is reduced, forming the front center portion with a non-stretchable cloth leads to large deformation of the side portions. Therefore, the breast meat sandwiched from the side can be firmly received without missing from the front center side. In addition, by forming the side part having a large amount of deformation with an elastic cloth, when the left and right first tension bands are drawn, only the side part can be smoothly drawn, and the front center part is The periphery of the cup portion can be reliably reduced in diameter without causing deformation or misalignment.

The side cloth that constitutes the side part and the back cloth that constitutes the back part are sewn on the side line, and the vertical length of the sewn part is in the range of 70 to 150 mm and extends to the center of the back side. The minimum vertical length of the above-mentioned back cloth is in the range of 40 to 110 mm, which is wider than a normal brassiere.
By forming the side cloth and the back cloth in a wide manner in this way, the contact area of the side cloth and the back cloth with respect to the trunk can be increased, and the brassiere can be stably supported.

Furthermore, it is preferable to arrange a core material having a width of 1 to 2 cm at the sewn portion along the side lines of the side cloth and the back cloth. The core material is preferably made of a flat plate-like bone made of resin, and a plurality of core materials may be arranged in parallel with the core material on the back cloth side in contact with the sewn portion along the side line. .
By arranging the core material along the side line position in this way, the side line of the brassiere can be stably held without being displaced from the position of the wearer's side line during the operation of pulling the peripheral edge of the cup in the diameter reducing direction. It is possible to reliably prevent the brassiere from shifting.

  Even when the breast is small, the brassiere having the above structure can be protruded so as to gather the meat of the breast to have a volume and squeeze the front. Therefore, the needle for testing can be easily inserted, and the needle does not penetrate the breast, so that it can be suitably used as a bra for breast cancer biopsy.

Furthermore, it is good also as a structure by which a cup cloth is detachably attached to the part opened not only by the bra for breast cancer biopsy but opened by the cup peripheral part, for example.
In this case, a cup cloth having an arbitrary design can be attached by attaching a rail-like member or the like to be concavo-convexly fitted between the cup peripheral edge and the cup cloth to be retrofitted.

As described above, the brassiere according to the present invention draws the left and right first tension bands in a state where the left and right second tension bands are sufficiently pulled, so that the side portions are drawn and the cup portion periphery is reduced. The breast and the meat around the breast can be gathered together in the periphery of the cup and pushed forward to increase the volume of the breast.
Therefore, when taking mammography breasts during mammotom biopsy, wearing the brassiere can increase the volume and maintain the state of small breasts. The necessary breast thickness can be ensured.

  Also, by arranging a core material such as a wire along at least the side edge of the cup part periphery, the side edge of the breast is pressed, and the breast meat escapes from the cup edge to the side and the volume is reduced. Can be prevented. Further, when the core material is divided into the front center side and the side side, the core material can be made to follow the burge line even when the breast is sandwiched between the mammography apparatus and compressed.

  Furthermore, when the front center part is formed of a non-stretchable cloth and the side part is formed of a stretchable cloth, the side part is smoothly drawn toward the center side when the diameter of the cup periphery is reduced. Stays in place and can catch the breast meat gathered from the side without missing at the front center part, and can concentrate the meat in the periphery of the cup part.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIGS. 1 to 5 show a breast cancer biopsy brassiere 10 according to a first embodiment of the present invention, which has no cup part covering the left and right breasts, and is located on the outer ring of the breast excluding the upper edge. The diameter of the peripheral edge 11 of the cup to be reduced can be reduced.

  That is, as shown in FIG. 1, the brassiere 10 includes a base cloth 12 that continuously covers the front center portion A located between the left and right breasts and the lower side portion B located below the left and right breasts, The left and right side cloths 13, 13 covering the side parts C, the left and right back cloths 14, 14, left and right first tension bands 15, 16 and left and right second tension bands 17, 18 are provided. The side cloths 13, 13 are sewn to the left and right ends of the cloth 12, and a pair of cup peripheral edges 11 are formed on the left and right along the breast outer ring from the front center side through the lower edge to the side upper edge. Yes.

  As shown in FIG. 2, the first wire 19 a and the second wire 19 b that constitute the core material are continuously attached to the back side along the cup periphery 11. Specifically, a first wire enclosing cloth 20a in which a first wire 19a is encapsulated is sewn to the cup part center side edge 11a formed by the base cloth 12, and the cup side edge 11b formed by the side cloth 13 is sewn. The second wire encapsulating cloth 20b enclosing the second wire 19b is sewn, and the wires attached to the left and right cup peripheral edges 11 are sewn at the sewn positions of the base cloth 12 and the left and right side cloths 13, 13. It is divided into one wire 19a and second wire 19b.

  The left and right first tension bands 15 and 16 are formed of a material having a strong tensile force, and are sewn to the upper edge 12a of the base cloth 12 as shown in FIGS. 1 and 2, and the first wire The enclosing cloths 20a and 20a are also sewn to the front center side ends. At this time, the first left tension band 15 extends from the upper edge 12a of the base cloth 12 to the upper edge of the left breast so that the left and right first tension bands 15, 16 are V-shaped at the front center portion A. One of the first right tension bands 16 is sewn diagonally upward along the upper edge 12a of the base cloth 12 from the upper edge 12a of the right breast.

Further, the left and right second tension bands 17 and 18 are also formed of the same material as the first tension bands 15 and 16 having a strong tensile force, and as shown in FIGS. From the end to the back cloth 14, the upper edges 13a, 13a of the left and right side cloths 13, 13 and the side edges of the second wire enclosing cloths 20b, 20b are sewn together. .
The second left tension band 17 extends from the upper edge 13a of the left side cloth 13 to the upper edge of the left breast, and the second right tension band 18 extends from the upper edge 13a of the right side cloth 13 to the upper side of the right breast. Along the edge, each is sewn diagonally upward.

  The first left tension band 15 and the second left tension band 17 are passed through one ring 21 above the left breast, and similarly, the first right tension band 16 and the second right tension band 18 are , Passed through the ring 22 above the right breast.

  After passing through the ring 21, the first left tension band 15 passes through the first retaining ring 23 through a tip annular portion 15 a formed by folding the tip. Further, the first right tension band 16 is passed through the ring 22, then passed through the second retaining ring 24, then passed back through the first retaining ring 23, and the tip annular portion formed by folding back the tip. The second retaining ring 24 is passed through 16a. Thus, the left and right first tension bands 15 and 16 are connected by the first retaining ring 23 and the length of the first right tension band 16 can be adjusted by the movement of the second retaining ring 24. That is, by moving the second retaining ring 24, the dimension between the left and right first tension bands 15, 16 can be expanded and contracted.

  The left and right second tension bands 17, 18 are passed through the left and right rings 21, 22 as described above, then through the second retaining rings 26, 26, and then sewn to the left and right back cloths 14, 14. The second retaining rings 26, 26 are passed through the annular annular portions 17 a, 18 a formed by folding through the first retaining rings 25, 25 that are attached and then folding the distal ends. Accordingly, the left and right second tension bands 17 and 18 also serve as left and right shoulder straps extending beyond the left and right shoulders to the back side, and the lengths can be adjusted by moving the second retaining rings 26 and 26, respectively.

The base cloth 12 is formed of a non-stretchable cloth, and the left and right side cloths 13 and 13 and the left and right back cloths 14 and 14 are both formed of a stretchable cloth. The side cloths 13 and 13 and the back cloths 14 and 14 are sewn to the left and right side lines, and are sewn to the rear center side end portions of the left and right back cloths 14 and 14, as shown in FIG. The left and right back cloths 14 and 14 are connected by locking the fasteners 27a and 27b to each other.
In addition, as shown in FIG. 2, on the back side along the lower end edge where the base cloth 12, the left and right side cloths 13, and the left and right back cloths 14 and 14 are continuous, there is a stretchable edge. The tape 30 is continuously sewn, and a narrow and stretchable edge tape 31 is sewn on the back side along the upper edge of the left and right back cloths 14 and 14.

  The sewn part H between the side cloths 13 and 13 and the back cloths 14 and 14 has a vertical length of 70 to 150 mm, and a flat plate-like resin having a width of 1 to 2 mm on the back side of the sewn part H. A core material enclosing cloth 29 enclosing a core material 28 made of bone-made bone is sewn over the entire length in the vertical direction. Moreover, the vertical length of the said back cloth 14 and 14 is set so that it may become small gradually toward the back center side, making the side side the maximum, and the minimum vertical length is 40-110 mm.

  As shown in FIG. 4 (A), the breast cancer biopsy brassiere 10 having the above-described configuration is obtained by adjusting the length of the second tension bands 17 and 18 with the second retaining rings 26 and 26 and sufficiently pulling them. When the positions of the second retaining rings 24 and 24 are adjusted so that the left and right first tension bands 15 and 16 are closer to the front center side, they are connected to the first tension bands 15 and 16 via the rings 21 and 22. The above-described second tension bands 17 and 18 are also drawn toward the front center side. As a result, as shown in FIG. 4B (only the right cup part is shown), the first and second tension bands 15, 16, 17, 18 are pushed down so as to bite into the upper edge of the breast, The left and right side cloths 13 and 13 and the left and right cup part side peripheral edges 11b and 11b sewn to the second tension bands 17 and 18 are also drawn upward and to the front center side. As shown in FIGS. 5 (A) and 5 (B), the breast meat in the peripheral edge 11 is squeezed, concentrated in the center, and raised forward. Therefore, even with a small breast, the volume can be increased by wearing the brassiere 10 and the state can be maintained. Therefore, even if the breast is compressed by a mammography apparatus, the thickness necessary for sampling can be ensured.

  In addition, since the wires 19a and 19b are attached to the cup peripheral edge 11, the wires 19a and 19b can prevent the breast meat from flowing out of the cup peripheral edge 11 by the barges. Since the wire 19a and the second wire 19b are divided, even when the breast is pressed flat by a mammography device, the wire easily bends and follows the bulges at the divided portion. You can keep pressing and maintain the required volume.

  Furthermore, since the side cloths 13 and 13 that require great deformation are formed of stretchable cloth, the side cloths 13 and 13 are smoothly pulled up according to the drawing of the first tension bands 15 and 16. The influence of the deformation on other parts can be minimized, and inappropriate displacement and deformation can be prevented. Moreover, by forming the base cloth 12 that does not require a large deformation with a non-stretch cloth, it can be received in place without missing the breast meat drawn to the front center side by the side cloths 13, 13. The breast can be effectively increased in volume.

  Furthermore, since the side cloths 13 and 13 and the back cloths 14 and 14 are both formed wide, it is possible to push and collect the back side and side part of the flesh to the breast side and to have a large contact area around the waist. Therefore, a sense of stability when the brassiere 10 is worn increases.

  FIG. 8 shows a modification of the first embodiment, in which only a second core material 50 made of a resinous bone is enclosed in a core material enclosing cloth 51 and attached along the side of the peripheral edge of the cup. Is lost. Further, as in the above embodiment, a core encapsulating cloth 29 enclosing the core material 28 is attached to the sewn portion along the side line of the side cloth 13 and the back cloth 14, and the back surface is adjacent to the core material 28. Two core members 53 and 54 may be arranged in parallel on the cloth 14 side.

FIG. 9 shows a second embodiment, in which the cup cloth 60 can be detachably attached to the opening surrounded by the cup periphery 11 by retrofitting.
A locking rail 61 having a convex cross section is attached along the lower half periphery of the cup cloth 60, and a locked rail 62 having a concave cross section is attached along the cup portion peripheral edge 11.
Therefore, when the cup cloth 60 is attached, the cup cloth 60 can be attached to the opening portion by fitting the locking rail 61 to the locked rail 62 and sliding.

  Further, the present invention is not limited to the above embodiment, for example, the expansion and contraction means for expanding and contracting the dimension between the left and right first tension bands is not limited to the turnbuckle method, and instead of the back-open type brassiere, It may be a front opening type or a covering type bra.
