Definitions
- the present invention relates to artificial breast implants with minimized stress concentration, and to a method of manufacturing the same, more specifically, to form a thickness of the silicon shell and the patch joint portion of the uniform thickness the same as the shell, and the physical properties of the shell and patch junction region It is configured in the same way and is provided with a step part and an uneven groove in the patch joint part so that the patch can be closely bonded inside the shell.
- the stress concentration phenomenon is minimized against the stress received by the prosthesis.
- breast implants are used for the reconstruction of breast defects due to diseases and accidents, and for cosmetic surgery and plastic surgery due to malformations, and are used for the replacement of organs or tissues three-dimensionally and anatomically.
- Prosthetic breast implants are saline, hydro-gel, and silicone gels that are filled inside a pouch made of silicone for organ transplantation (hereinafter referred to as "shell", a common term in the art). ), Round type and droplet type depending on the shape, smooth type and rough type depending on the surface condition. Can be summarized as described below.
- Saline breast prosthesis is a type of implantable or implantable artificial breast implant that consists of a silicone shell and a valve.
- Saline artificial breast implants have the advantage that the volume of the breast can be changed by guaranteeing the safety of the fillings in the body after rupture and controlling the amount of saline filling after the use of sterile saline as a filler.
- the disadvantage is that it is significantly lowered and the shell is less durable.
- Hydrogel-filled breast prosthesis is a form of hydrogel filled with monosaccharides and polysaccharides inside a shell such as saline artificial breast implants. This product was developed on the principle of absorption and excretion.
- hydrogel prosthetic breast implants have not been proven to be safe for long-term use, have a large volume change over time after insertion and a high possibility of wrinkles, and have an unnatural feel compared to silicone artificial breast implants.
- Such hydrogel artificial breast implants are not fully distributed in the market due to the issue of safety verification as of 2000.
- Silicone gel-filled breast prosthesis is a form filled with silicone gel of moderate viscosity inside the shell, and the durability and feel of the product is superior to that of saline artificial breast implants. Sales of artificial breast implants are in a position where sales of silicone artificial breast implants dominate. Silicone gel breast implants were restricted for use by the US Food and Drug Administration (FDA) because of their safety demonstration, but were again officially licensed in 2006.
- FDA US Food and Drug Administration
- silicone artificial breast implants The development history of silicone artificial breast implants has been developed as first generation implants, second generation implants, and third generation implants, and the details are as follows.
- Second-generation silicone artificial breast implants were sold from the mid-1970s to the mid-1980s, using thin shells and low-viscosity silicone gel fills for a softer feel. This implant is characterized by similar gel runoff, high rupture rate, and low spherical incidence compared to first generation implants.
- the 3rd generation silicone artificial breast implants have been sold from the mid-1980s to the present, using a gel barrier layer to block gel outflow, and a thick shell and high viscosity silicone compared to the second generation.
- Gel is the form used.
- a rough surface product (Texture type) has been developed to reduce spherical construction.
- shell joints All of these artificial breast implants are referred to as shells and joints (hereafter referred to as "patch joints"), which is a common term in the art, collectively referred to in the art as blocking the pores that occur during the removal of the shell from the moles. And the filling.
- the shell manufactured by the immersion method causes a thickness variation between the upper and lower portions of the shell due to gravity, and the thickness variation causes a relatively weak spot due to stress.
- the thickness of the lower portion is very much compared to increasing the overall thickness of the shell As the thickening occurs, there is a limit to the flexibility that the breast implants must have. For example, as the thickness of the upper portion of the shell having an average thickness of 1 mm or less increases by 0.3 mm, the thickness of the lower portion may be increased by about 1 mm, and the thickness deviation is further increased.
- the patch bonding part is used for the patch (additional bonding material) and the bonding material used for bonding, in the manufacture of artificial breasts, the patch used as the bonding material for the patch bonding site is the same thickness and the same physical properties as the shell Use materials that represent them.
- the patch must be made in the form of a multi-layered sheet containing an anti-spill layer of low molecular silicon inside the patch to prevent the patch from degrading in strength.
- it is because it is very difficult commercially and technically to manufacture a patch of a thinner film than the shell while including the barrier layer therein. Therefore, in the art, a part of the shell is usually cut off and used as the patch.
- the conventional implant uses a patch 6 having the same thickness as the thickness (average thickness 0.5 to 1 mm) of the silicon shells 5 and 7, as shown in FIG.
- the patch bonding site 8a becomes very thick and the elongation characteristics of the patch bonding site are almost disappeared.
- the patch bonding site 8a is configured as shown in FIG. Since is thinner than the peripheral part, stress concentration occurs due to the difference in physical properties between the boundary points of the silicon shell 7 and each patch jointing part 8b, which causes problems in the durability of the patch 6 in fatigue. Due to the clinical results, the rupture around the patch of the prosthetic breast is very frequently occurring.
- USP 6074421 describes patch joints of artificial breast implants in which joint lines are not visible.
- the feature of this technique is a patch joining technique of a patch joining portion having a structure as shown in FIG. 1 (b), and the patch 6 is formed by inclining an edge in the hole of the shell 7 at the portion where the patch 6 joins.
- the articulation of artificial breast implants which can give aesthetic appearance as the joint lines between the shell 7 and the patch 6 are not visible by bonding, is described.
- the above-described prior art focuses only on the improvement of the appearance of the artificial breast implant, and the consideration of the performance improvement part of the entire implant including durability is insufficient. Therefore, the prosthesis may be beautiful in appearance, but since the patch has the same thickness as the shell, part of the patch joint is very thick and thin at the center of the patch joint, whereby the patch joint and the patch joint are thinner.
- the stretch and tensile properties between the silicone shells are different from each other, and stress concentration occurs due to the difference in physical properties between the shell and the junction area, which has problems in durability against fatigue. Is the same as
- EP 0872221A1 which describes a patch-joining portion of an artificial breast implant in which a seam is not visible, is basically included in the description of FIG.
- An additional technique for the implantation of artificial breast implant patches which is characterized as In the prior art, a layer as shown in the drawing is formed on the outer side of the shell 7 around the hole to be patch-bonded, and then the patch 6 is bonded to the portion, whereby the joint line between the shell 7 and the patch 6 is joined.
- This invisibility refers to artificial breast implants that can give a cosmetic appearance.
- the overlapping portion 8a between the shell 7 and the patch 6, such as the patch bonding portion of FIG. 1 does not occur on the outside of the shell, which is a part of the naked eye.
- the technique is similar to the prior art, and the center portion 8b of the patch junction portion is thinner than the peripheral portion, and thus, at the boundary portion of the patch junction portion due to the difference in physical properties between the other patch junction region and the silicon shell. Stress concentration phenomenon occurs, so it is the same as other existing artificial breast manufacturing technology which has a problem in durability against fatigue.
- the bonding structure of the above technique is a structure in which a hole is blocked from the outside, and as seen in FIG. It is an easy structure.
- the joint structure of this technology concentrates the pressure applied to the implant according to the user's movement after implantation of the implant in a smaller area than the pressure at the site where the patch is bonded.
- the bonding structure having a more mechanically and physically stronger and superior bonding durability against the pressure applied to the prosthesis after insertion of the human body is a structure in which a patch is bonded from the inside by placing a layer or a step inside the shell.
- the prior art described above is not a technology that initially solves the physical characteristics and durability of the product and its components, but is a technology limited only in terms of improving the product outward.
- Technical considerations regarding the durability of the entire implant, including the pressure applied to the joint structure according to the movement after implantation of the implant and the bonding durability thereto, are insufficient.
- the bonding material 11 used in the process of bonding the already-cured silicone shell and a patch piece having a certain thickness to be cured together is very high in viscosity.
- liquid silicone rubber (LSR) or silicone gum (gum) can only be used.
- the high-viscosity liquid silicone or silicon gum bonding material 11 or the bonding material 11 has a high viscosity. This is because only the bottom portion is not applied to the side portions of the patch pieces, so that the shell and the side portions of the patch pieces have a limitation in that they cannot be bonded to each other.
- the prior art bonding structure is a technology focused only on the appearance improvement of the artificial breast implant, and consideration of physical performance improvement including bonding durability and overall durability of the implant is very poor.
- the needle is injected through a separate injection device to inject the filling material, and after the filling of the filling material is completed, the needle is removed.
