Description

Technical Field

[0001] The utility model relates to an upper-type breast gathering and lifting net implanted in the body, and more specifically, to a breast gathering and lifting net implanted in the body to improve breast sagging. Background Art

[0002] There are many reasons that can cause sagging breasts in women. For example, breastfeeding and aging can cause the skin to loosen and lose its original tension, causing the breasts to sag when standing and to spread out too much when lying down. In extreme cases, the breast tissue spreads out on the chest like liquid, making it almost difficult to tell the proper shape of the breasts. Restoring the breasts to the shape and firmness of women's youth and increasing women's self-beauty, self-awareness and self-confidence are the goals that medical aesthetics practitioners strive for.

[0003] Chinese patent application CN200910036937.3 discloses a structure and preparation method of a breast prosthesis with a support and traction belt. This breast prosthesis with a support and traction belt is different from existing breast prostheses. It is provided with a plurality of membrane belts or strips extending outwards. Through these membrane belts and strips, the prosthesis can be easily supported and fixed in the most suitable position for the human body, without having to rely entirely on the tissue around the patient's breast for support, which can reduce the probability of sagging. It is especially suitable for patients who have already experienced breast sagging before implantation or patients after breast cancer resection. The structure of this patent application is intended to lift the prosthesis and prevent the prosthesis from sagging, and is not applicable to the surgery of self-breast lifting.

[0004] Chinese utility model patent CN 201520940562.4 discloses an implant system for minimally invasive breast lift surgery, the system comprising: one or more fixing components for fixing to body tissue, one or more suspension components connected to the fixing components, and one or more support components connected to the suspension components, wherein the suspension components have no free ends and are not adjustable. The utility model also discloses a tool combination for minimally invasive breast lift surgery, the tool combination comprising: at least one fixing component and a fixing tool for connecting the fixing component to body tissue, at least one suspension component and at least one support component.

[0005] In addition, Chinese patent CN 03817459.6, US patents US5,217,494, US5,584,884, US7,670,372, US8,858,629, etc. all adopt the technology of fixing or anchoring a prosthesis to a certain part of the body such as a bone. The disadvantage of this technology is that the patient needs to pay attention to his life after the operation.

[0006] Chinese utility model patent CN 201921751087.0 discloses a breast prosthesis fixing device, which comprises a base (1) and a mask (2), wherein the base (1) is composed of a disc-shaped base body (11) with a through hole made of medical silica gel and a plurality of artificial ligaments (12), each of which is radially dispersed with the base body (11) as the center, one end of which is connected to the outer periphery of the base body (11) along the radial direction of the base body (11), and the other end of which is directed toward the base body. (11) In the opposite direction of the center, the mask (2) is a disc-shaped body made of medical silicone. A plurality of ligament holes (21) matching with the artificial ligaments (12) on the base (1) are circumferentially dispersed near the edge of the mask (2). The free ends of the artificial ligaments (12) not connected to the base body (11) pass through the ligament holes (21) on the mask (2) one by one. The base body (11) and the mask (2) are surrounded by an anti-displacement cavity for accommodating a breast prosthesis. The utility model is used to fix a prosthesis, and is used in surgery for implanting a prosthesis to assist in the fixation of the prosthesis. Its two structures are respectively placed on the upper and lower surfaces of the prosthesis, and are connected to the small holes through artificial ligament strips. The former extends deep into the surrounding tissues, like a drawstring to set up a tent. The breast prosthesis fixing device of the utility model is intended to lift the prosthesis and prevent it from sagging, but it is not applicable to situations where a prosthesis does not need to be implanted, and is not applicable to surgery for self-breast lifting.

[0007] Chinese patent application CN 202280016915.4 discloses a breast implant, which includes an integral elongated member having a first end and a second end and sized to surround the breast under the skin, and the member used is a band, a membrane, a porous membrane, a textile, a braid, a knitted mesh or fiber, a woven mesh or fiber, or a non-woven mesh or fiber, or a disconnected tangled mesh. The structure of the patent application is similar to a "barrel hoop", which tightens the mammary gland from the periphery. The connection at its head end is like the buckle of a watch strap. The purpose of this solution is not to use a prosthesis, especially a filled prosthesis, to improve the shape of the chest, but to improve the distribution of breast tissue in the human body itself, but the disadvantage of the solution recorded in the patent application is that if the "barrel hoop" is tightened, the soft breast tissue will bulge out where there is no hoop. Because it is not an integral wrapping method.

[0008] In the existing technology, there is no better solution to the problem of sagging breasts than using an inverted "T" surgery to remove sagging breast skin tissue or double ring suture. However, the disadvantages of this technology are: although the removal of breast tissue can raise the sagging breast, it will definitely leave obvious scars. The trauma and permanent scars caused by this type of surgery are undesirable side effects; and the double ring breast reduction method will also paralyze the smooth muscle of the areola, flatten the areola like a pancake, and leave obvious ring scars; in addition, it is difficult to maintain the surgical results for a long time after the operation, because with changes in weight, age and the stretching of the skin by the weight of the breasts, the shape of the breasts will be affected again, causing sagging.

[0009] Therefore, it is necessary to provide a kind of fixation device that is implanted in vivo, improves the distribution shape of breast tissue, and this device can gather all sagging breast tissue, so that the breast no longer sags when standing, and the breast no longer flattens when lying flat. Summary of the invention

[0010] The utility model aims to provide a device which can improve the distribution of breast tissue in vivo and thus change the shape of breasts, and the device can avoid the removal of breast tissues and the implantation of breast prostheses, especially the use of filled breast prostheses.

[0011] In order to achieve the above-mentioned purpose of the utility model, the utility model provides an upper-type breast gathering and lifting net implanted in the body, the breast gathering and lifting net comprising a disc-shaped object and a plurality of strips connected to the outer edge of the disc-shaped object and distributed on the outer edge; wherein the disc-shaped object is a circular disc, an elliptical disc, or a circular disc or an elliptical disc with a protruding portion on the edge, the disc-shaped object has a thickness of 0.3-5mm, a circular diameter or a maximum elliptical diameter of 20-120mm, and the disc-shaped object at least comprises A through hole, the width of the outer edge of the disc is 3-10mm; the number of strips used is 6-96, and the shapes of the strips are thin lines, sheets without holes, sheets with holes, thin lines with rough surfaces, thin lines with teeth on the surface, sheets with teeth on the surface or sides, or sheets with rough surfaces. The length of the strips is 50-300mm, the thickness is 0.5-2mm, and the width is 2-10mm; the above-mentioned breast gathering and lifting net is made of flexible material without any filler inside.

[0012] The breast gathering and lifting net of the utility model can only be used by doctors for patients in need during surgery. The breast gathering and lifting net of the utility model belongs to the upper type breast gathering and lifting net, because its disc-shaped object refers to the diameter of the areola. During the operation, a circular incision is first made around the areola, and then the strips are inserted into the superficial layer of the breast (subcutaneous layer of the breast) one by one according to the line marks, and then pass through the edge of the breast, and then fold back from the exit point and insert into the deep layer of the breast, tighten the strips, and thus tighten the diameter of the breast. Figure 2 .

[0013] The above operations are assisted by special surgical instruments. Since the strip has inverted teeth, the strip will not slide out of the original path. After all operations are completed, the mammary glands are wrapped by the mammary gland gathering and lifting net of the utility model, just like the Chinese "wrapping zongzi". In this way, the breasts are no longer loose and sagging, but are firmly gathered, and the glands around them are close to each other and centered. If the strip is hung to the head end of the chest, it can play the role of lifting the breasts, and the sagging of the breasts can be improved.

[0014] In the breast-gathering and lifting net of the utility model, the thickness of the disc is only 0.3-5 mm, and such thickness is difficult to feel from the outside after implantation in the body, while the strip is in the shape of a thin line or a sheet, and the thickness of the sheet strip is often less than the thickness of the disc, generally not exceeding 2 mm, and is also difficult to feel from the outside after surgery. Preferably, the thickness of the sheet strip is 0.5-1.6 mm, and more preferably, the thickness of the sheet strip is 0.5-1 mm. The width of the sheet strip can be controlled between 2-8 mm, and preferably between 2-6 mm.

[0015] In the breast gathering and lifting net of the utility model, due to the large number of strips, the entire breast tissue is more tightly "wrapped" as a whole, and there is no phenomenon that the soft breast tissue protrudes from the gaps between the strips. If sheet strips are used, their number is negatively correlated with their width: when the sheet strips are relatively wide, their number can be relatively small. Generally speaking, the preferred number of strips is 8-48, and the more preferred number of strips is 12-36.

[0016] In the breast gathering and lifting net of the present invention, the strips are preferably evenly distributed and connected to the outer edge of the disc, but according to the special circumstances of individual patients, the strips may also be unevenly distributed on the outer edge of the disc.

[0017] In the breast gathering and lifting net of the utility model, the strips and the discs can be integrally formed, or they can be separate and then reprocessed to form a whole, so that each strip is connected to the outer edge of the disc, or they can be combined during use. Preferably, they are integrally formed.

[0018] As a specific embodiment of the utility model, in the breast gathering and lifting net of the utility model, the circular diameter or the maximum elliptical diameter of the disc-shaped object used is 20-80 mm, and a large through hole is arranged at the center of the disc-shaped object, which corresponds to the diameter of the areola. The size of the large through hole is close to the size of the disc-shaped object used, that is, except for the edge of the disc-shaped object, the other positions of the disc-shaped object are through holes.

[0019] As another specific embodiment of the present invention, in the breast gathering and lifting net of the present invention, the circular diameter or the maximum elliptical diameter of the disc-shaped object used is 50-120mm, and a larger through hole is arranged at the center of the disc-shaped object, which corresponds to the diameter of the areola; and a plurality of smaller through holes, for example, 4-32 smaller through holes, are distributed around the periphery of the larger through hole and between the edges of the disc-shaped object.

[0020] In the breast gathering and lifting net of the utility model, the number of strips is closely related to the diameter of the disc and the width of each strip. For example, if the diameter of the disc is large and the width of a single strip is small, the number of strips is large; conversely, if the diameter of the disc is small and the width of a single strip is large, the number of strips is small.

[0021] In the breast gathering and lifting net of the present invention, the shapes of the through holes used are circular, elliptical, regular polygonal, and polygonal; if the number of the through holes exceeds one, the shape of the through holes can be one of the above shapes or a combination thereof.

[0022] Preferably, in the above-mentioned breast gathering and lifting net of the utility model, the strip is in the shape of a sheet with holes and teeth on the side, and the hole here is a through hole. Teeth are provided on the strip, especially when inverted teeth are provided, so the strip will not slide out of the original path. In this way, on the one hand, it is convenient for surgery, and on the other hand, it is convenient for postoperative fixation. The purpose of providing the through hole is to facilitate the growth of human tissue in the through hole after surgery, so as to fix the strip.

[0023] Further preferably, in the above-mentioned breast gathering and lifting net of the utility model, the above-mentioned strip is provided with neither through holes nor teeth near the disc. For example, starting from the outer periphery of the outer edge of the disc, there is no through hole, teeth, etc. at a position of about 10-60 mm in the strip, that is, the strip in this section is smooth or nearly smooth.

[0024] In the breast gathering and lifting net of the utility model, the shapes of the strips can be the same or different. Preferably, the shapes of the strips are the same, because this is convenient for doctors to operate, and different shapes require doctors to adapt differently.

[0025] For example, in the present invention, silicone rubber or a copolymer or mixture of silicone rubber and other physiologically and mechanically acceptable components with an elastic modulus within the above range can be selected. Here, silicone rubber refers to a rubber whose main chain is composed of alternating silicon and oxygen atoms, and the silicon atom is usually connected to two organic groups, and is a type of polysiloxane.

[0026] In the breast gathering and lifting net of the utility model, an indentation line for facilitating cutting can be provided on the strip, so that the doctor can cut the strip into a suitable length according to the specific situation.

[0027] In the breast-pushing and lifting net of the utility model, the rough-surfaced strips, such as the rough-surfaced fine-line strips or the rough-surfaced sheet strips, can be particles with protrusions distributed on the surface. For example, for the sheet strips, the protrusions can be distributed on both sides of the sheet, or only on one side of the sheet.

[0028] The breast gathering and lifting net of the utility model is different from the filling breast prosthesis and the devices for fixing the breast prosthesis. Its disc-shaped object + multiple strip-shaped objects structure can "wrap" the breast tissue as a whole, and this "wrapping" is relatively tight, and no breast tissue will protrude from the gap of the wrapping. Since the disc-shaped object is relatively thin and uses a flexible material with appropriate Shore A hardness, elastic modulus and Poisson's ratio, it is difficult to be touched from the outside after the operation. Doctors use the breast gathering and lifting net of the utility model in the operation, which can solve the problem of sagging breasts well, with good effects, small surgical trauma, less bleeding, and fast recovery, so as to achieve the purpose of patients' chest lifting.

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The silicone rubber used in this application is solid medical grade silicone rubber Nus il473 produced by Nus il Company in the United States.

[0046] Example

[0047] Silicone rubber with a Shore A hardness of about 35, a Young's modulus of about 0.3 MPa, and a Poisson's ratio of about 0.43 is selected as the flexible material for preparing the breast gathering and lifting net of this embodiment, and an integrated molding process is used to prepare the breast gathering and lifting net. Figure 1 The breast gathering and lifting net shown. The breast gathering and lifting net 1 comprises a circular disc 2 with a thickness of about 2 mm, a diameter of about 60 mm, a large through hole 3 in the center of the circular disc 2, and a width of an outer edge 4 of the circular disc 2 of about 6 mm.

[0048] The breast gathering and lifting net 1 also includes 24 sheet-like strips 5, the length of which is about 150 mm. The sheet-like strips 5 are not provided with through holes 6 and teeth 7 in the section of about 20 mm near the outer edge 4 of the circular disc 2, while the sheet-like strips 5 are provided with through holes 6 and teeth 7 in the remaining sections. The sheet-like strips 5 are about 0.5 mm thick and about 2.8 mm wide, the diameter of the through holes 6 is about 1 mm, and the height of the teeth 7 is about 0.8 mm.

[0049] The surgical method of this upper type lifting mesh is to first make a circular incision around the areola, then insert the strips one by one into the superficial layer of the breast (subcutaneous layer of the breast) according to the marked lines, and then pass through the edge of the breast, and then fold back from the exit point and insert into the deep layer of the breast. Tightening the strips will also tighten the diameter of the breast. Please refer to Figure 2 ;

[0050] After all operations are completed, the mammary glands are wrapped by the mammary gland gathering and lifting net of the embodiment, just like "wrapping zongzi" in China. In this way, the breasts are no longer loose and sagging, but firm and gathered, and the glands around them are close to each other and centered.
