Description

의료용 보형물Medical implants
본 발명은 의료용 보형물에 관한 것으로서, 인체의 복원, 미용 등의 목적으로 이용가능한 인체적합성을 갖는 보형물에 관한 것이다.The present invention relates to a medical implant, to a implant having a human compatibility that can be used for the purpose of restoration of the human body, cosmetics, and the like.
의료용 보형물은 불의의 사고 또는 질병으로 인하여 함몰 등 손상된 인체를 복원하거나 여성의 가슴 등의 외관을 향상시키기 위한 목적으로 이용된다. 예를 들어 종양 제거 후에 필요할 수 있는 가슴의 볼륨 복원, 또는 가슴의 형상을 미적으로 향상시키기 위하여 이용될 수 있다.Medical implants are used for the purpose of restoring a damaged human body such as depression due to an accident or disease or to improve the appearance of a woman's breast. For example, it can be used to restore the volume of the chest, which may be necessary after tumor removal, or to aesthetically improve the shape of the chest.
여성의 가슴을 위한 보형물의 경우 두께 1 내지 2mm의 하드 타입의 실리콘 파우치 내에 액상 즉, 겔 타입의 실리콘이 주입된 보형물이 개발된 바 있다. 이러한 실리콘 파우치를 이용하는 종래의 보형물의 경우 도 1에 도시된 바와 같이 사용 상태에 따라 보형물(100p)의 외표면에 주름, 즉 리플링(Sh)이 형성되고, 이러한 주름이 인체의 외형에 그대로 반영되어 외관면에서의 문제점을 유발하는 경우가 있었다.In the case of implants for female breasts, implants in which a liquid, that is, gel-type silicon is injected into a hard type silicone pouch having a thickness of 1 to 2 mm have been developed. In the case of a conventional implant using such a silicon pouch, wrinkles, that is, ripples (Sh), are formed on the outer surface of the implant 100p according to the use state as shown in FIG. 1, and the wrinkles are reflected on the appearance of the human body as it is. This may cause problems in appearance.
또한 이와 같은 리플링(Sh)이 형성되는 경우 인체 삽입 후 인체 내의 조직과의 마찰에 의하여 보형물(100p)이 파손될 우려가 있으며, 실리콘 파우치가 파손되어 내부의 실리콘 겔이 인체로 유출되는 경우 실리콘 겔이 인체의 조직에 흡수되어 해당 조직을 괴사시키는 등의 문제가 발생할 우려가 있었다.In addition, if such a ripple (Sh) is formed, the implant 100p may be damaged by friction with tissues in the human body after insertion of the human body, and when the silicone pouch is broken and the internal silicone gel is leaked to the human body, the silicone gel may be damaged. There was a fear that a problem such as being absorbed into the tissue of the human body and causing necrosis of the tissue.
이러한 이유로 하드 타입의 실리콘 파우치를 2겹으로 제조하여 파손 가능성을 줄이거나, 실리콘 겔을 생리 식염수 또는 코히시브젤(cohesive gel)로 대체하여 생체 적합성을 증가시키기 위한 노력들이 있었다.For this reason, efforts have been made to increase the biocompatibility by making hard-type silicone pouches in two layers to reduce the possibility of breakage or to replace the silicone gel with physiological saline or cohesive gel.
그러나 하드타입의 실리콘 파우치를 2 중으로 하는 경우 강도가 강하여 인체의 촉감과는 다른 이질적인 감촉을 유발하는 문제점이 있으며, 여전히 파손 시의 위험성이 잔존하였다.However, when the hard type silicon pouch is doubled, there is a problem that the strength is strong, causing a heterogeneous texture different from the human touch, and there is still a risk of breakage.
또한 생리 식염수로 실리콘 겔을 대체한 보형물의 경우 감촉이 좋지 않고 시술대상자 본인이 일상 생활 시에 이질감을 느끼는 등의 문제가 발생하였으며, 코히시브젤을 이용한 보형물의 경우 촉감이 좋지 않고 일상 생활시에 보형물의 강도가 강하여 모양의 변형이 인체와는 달리 이질적인 느낌이 들도록 하는 문제가 있었다.In addition, the implants that replaced the silicone gel with physiological saline caused problems such as poor texture and the subjects felt heterogeneity in their daily lives. There was a problem that the deformation of the shape is so strong that it feels heterogeneous unlike the human body.
이와 같이 인체용 보형물은 인체와 유사한 감촉이 들어야 하며, 인체적합성 또는 안정성이 높아야 하고, 일상 생활에 따른 모양의 변형이 주름이 형성되지 않으면서 인체와 유사하여 이질적이지 않아야 한다.As such, the implant for human body should have a texture similar to the human body, high human suitability or stability, and should not be heterogeneous because the deformation of the shape according to daily life is similar to the human body without wrinkles being formed.
본 발명은 보형물의 외형에 형성되는 주름을 최소화함으로써 장시간 인체 내에 삽입된 상태에서도 마찰의 발생을 최대한 억제하고 안정성을 향상시킬 수 있는 보형물을 제공한다.The present invention provides a prosthesis that can minimize the occurrence of friction and improve stability even when inserted into the human body for a long time by minimizing wrinkles formed on the contour of the prosthesis.
또한 본 발명은 일상생활 시에도 모양의 변형이 자연스럽고 이질적인 느낌을 최소화할 수 있는 의료용 보형물을 제공한다.In another aspect, the present invention provides a medical implant that can minimize the heterogeneous feeling of natural shape deformation during everyday life.

또한 상기 파우치는 실리콘 및 폴리우레탄 중 적어도 어느 하나의 재질로 형성될 수 있다.In addition, the pouch may be formed of at least one material of silicon and polyurethane.
또한 상기 보강부는 형상 및 배열면에서 규칙적으로 형성될 수 있다.In addition, the reinforcement may be formed regularly in shape and arrangement.
또한 상기 보강부는 제1 방향으로 형성되는 복수의 제1 돌출부와 제2 방향으로 형성되는 복수의 제2 돌출부가 교차되는 격자형상으로 형성될 수 있다.The reinforcement part may be formed in a lattice shape in which a plurality of first protrusions formed in a first direction and a plurality of second protrusions formed in a second direction cross each other.
또한 상기 보강부는 상기 제1 돌출부가 상부 중앙으로부터 하향 방사상 방향으로 형성될 수 있다.In addition, the reinforcing part may be formed in the radial direction downward from the upper center of the first protrusion.
또한 상기 보강부는 상기 제2 돌출부가 직선형 및 곡선형 중 어느 하나의 형상으로 형성될 수 있다.In addition, the reinforcing part may be formed in the shape of any one of the straight and curved second protrusion.
또한 상기 보강부는 육각형의 형상으로 돌출된 형상으로 형성될 수 있다.In addition, the reinforcement may be formed in a shape protruding in the shape of a hexagon.
또한 상기 보강부는 상기 파우치와 일체형으로 형성될 수 있다.In addition, the reinforcing portion may be formed integrally with the pouch.
또한 상기 보강부는 몰드(mold)에 의한 제조방법 및 사출방법 중 어느 하나의 방법에 의하여 상기 파우치와 일체형으로 형성될 수 있다.In addition, the reinforcing portion may be formed integrally with the pouch by any one of a manufacturing method and an injection method by a mold (mold).
본 발명에 따르면 보형물의 외형에 형성되는 주름을 최소화함으로써 장시간 인체 내에 삽입된 상태에서도 마찰의 발생을 최대한 억제하고 안정성을 향상시킬 수 있다.According to the present invention, by minimizing wrinkles formed on the contour of the prosthesis, the occurrence of friction can be suppressed to the maximum and stability can be improved even when inserted into the human body for a long time.
또한 본 발명에 따르면 직립 상태, 누웠을 경우를 포함하여 어떠한 자세에서도 상부의 외형면에서 주름의 발생을 최소화함으로써 일상생활 시에도 모양의 변형이 자연스럽고 이질적인 느낌을 최소화할 수 있다.In addition, according to the present invention by minimizing the occurrence of wrinkles in the upper surface in any posture, including the upright state, when lying down, it is possible to minimize the natural and heterogeneous feeling of shape deformation during everyday life.
또한 피부가 상대적으로 얇은 사람들의 경우에도 이러한 리플링을 최소화하는 효과를 얻을 수 있다.People with relatively thin skin can also benefit from minimizing this ripple.

또한 보강부(115)는 형상 및 배열면에서 규칙적으로 형성될 수 있다. 도 3을 참조하여 설명하면, 보강부(115)는 제1 돌출부(1151)와 제2 돌출부(1152)를 포함한다. 제1 돌출부(1151)는 제1 방향으로 길이를 갖는 돌출된 형상으로 형성되고, 제2 돌출부(1152)는 제1 방향과 일정한 각도를 형성하는 제2 방향으로 길이를 갖는 돌출된 형상으로 형성된다. 제1 돌출부(1151)와 제2 돌출부(1152)는 서로 교차되는 형상으로 형성됨으로써 격자를 형성한다.In addition, the reinforcement 115 may be formed regularly in shape and arrangement. Referring to FIG. 3, the reinforcement 115 includes a first protrusion 1151 and a second protrusion 1152. The first protrusion 1151 is formed in a protruding shape having a length in a first direction, and the second protrusion 1152 is formed in a protruding shape having a length in a second direction forming a constant angle with the first direction. . The first protrusion 1151 and the second protrusion 1152 are formed in a shape that intersects each other to form a lattice.
이와 같이 보강부(115)는 파우치(110)와 일체형으로 형성되며 격자 구조로 형성되어 파우치(110)의 두께를 일정한 패턴으로 보강하게 된다. 이와 같이 보강부(115)는 파우치(110)의 내측면 또는 외측면에 형성되어 파우치(110)에 찌그러짐이나 뒤틀림에 따른 형상의 변형 또는 주름이 형성되는 것을 최대한 방지함으로써 인체 내에 삽입된 상태에서도 마찰의 발생을 최대한 억제하고 안정성을 향상시킬 수 있으며, 직립 상태에서 상부의 외형면에서 주름의 발생을 최소화함으로써 일상생활 시에도 모양의 변형이 자연스럽고 이질적인 느낌을 최소화할 수 있다.As such, the reinforcement part 115 is formed integrally with the pouch 110 and is formed in a lattice structure to reinforce the thickness of the pouch 110 in a predetermined pattern. As such, the reinforcement part 115 is formed on the inner side or the outer side of the pouch 110 to prevent the deformation or wrinkle of the shape due to dents or distortions on the pouch 110 as much as possible to prevent friction even when inserted into the human body. It is possible to suppress the occurrence of the maximum and improve the stability, and by minimizing the occurrence of wrinkles in the upper surface in the upright state, it is possible to minimize the natural and heterogeneous feeling of shape deformation during everyday life.
도 4 및 도 5를 참조하여 다른 실시예에 따른 의료용 보형물의 파우치를 설명한다. 도 4는 다른 실시예에 따른 의료용 보형물의 파우치의 일 표면을 나타내는 개략도이고, 도 5는 또 다른 실시예에 따른 의료용 보형물의 파우치의 일 표면을 나타내는 개략도이다.A pouch of a medical implant according to another embodiment will be described with reference to FIGS. 4 and 5. 4 is a schematic view showing one surface of a pouch of a medical implant according to another embodiment, and FIG. 5 is a schematic view showing one surface of a pouch of a medical implant according to another embodiment.
도 4를 참조하여 설명하면, 보강부(115b)는 상부 중앙으로부터 방사상으로 형성될 수 있다. 구체적으로 제1 돌출부(1151b)는 상부 중앙으로부터 하향 방사상으로 길이 방향을 갖도록 형성한다. 또한 제2 돌출부(1152b)는 제1 돌출부(1151b)와 교차되도록 형성된다. 제2 돌출부(1152b)는 직선형 또는 곡선형으로 형성될 수 있다.Referring to FIG. 4, the reinforcement 115b may be formed radially from the upper center. Specifically, the first protrusion 1151b is formed to have a lengthwise direction radially downward from the upper center. In addition, the second protrusion 1152b is formed to intersect the first protrusion 1151b. The second protrusion 1152b may be formed in a straight or curved shape.
이와 같이 보강부(115b)는 상부 중앙으로부터 하향 방사상으로 형성되어 상부는 좁고, 하부는 넓은 간격으로 형성된다. 이와 같이 주름이 다수 형성되는 상부의 경우 좁은 간격으로 보강부(115b)가 형성되도록 하고, 식염수가 아래로 몰림에 따라 주름이 발생하기 어려운 하부의 경우에는 제2 돌출부(1152b)의 간격이 넓게 형성되도록 하거나, 제2 돌출부(1152b)를 형성하지 않음으로써 촉감면에서의 이질적인 느낌을 최소화할 수 있다. 이 때 제1 돌출부(1151b)의 경우에도 하부로 갈 수록 점차 간격을 넓게 형성하는 것이 바람직하다.As described above, the reinforcement part 115b is formed radially downward from the center of the upper part so that the upper part is narrow and the lower part is formed at a wide interval. As described above, in the case of the upper part in which many wrinkles are formed, the reinforcement part 115b is formed at a narrow interval, and in the case of the lower part in which the wrinkles are less likely to occur as the saline solution is pushed downward, the interval of the second protrusion part 1152b is wider. Or by not forming the second protrusion 1152b, the heterogeneous feeling in the tactile surface can be minimized. At this time, the first protrusion 1151b also preferably forms a wider gap gradually toward the lower portion.
도 5를 참조하여 설명하면, 보강부(115c)는 육각형의 형상으로 돌출된 형상으로 형성될 수 있다. 이와 같이 형성하는 경우 유각형의 돌출된 형상이 견고한 보강 구조를 형성함으로써 보다 안정적인 주름 방지 효과를 얻을 수 있다.Referring to FIG. 5, the reinforcement part 115c may be formed to protrude in a hexagonal shape. When forming in this way it is possible to obtain a more stable anti-wrinkle effect by forming a solid reinforcing structure of the bulge-shaped protruding shape.
다만, 앞서 설명한 바와 같이 인체내 삽입된 상태를 기준으로 의료용 보형물의 상부는 주름 방지의 기능이 보다 중요한 반면, 의료용 보형물의 하부는 주름이 형성되기 어려워 이러한 기능 보다 촉감면에서의 기능이 더욱 중요하다.However, as described above, the function of preventing wrinkles is more important on the upper part of the medical implant based on the inserted state in the human body, while the lower part of the medical implant is difficult to form wrinkles, so the function in touch is more important than this function. .
이러한 기능의 구현을 위하여 의료용 보형물의 상부는 보강부(115c)의 두께를 상대적으로 두껍게 형성하고, 의료용 보형물의 하부는 보강부(115c)의 두께를 상대적으로 앏게 형성하거나 형성하지 않는 것이 바람직하다.In order to implement such a function, the upper portion of the medical implant may be relatively thick, and the lower portion of the medical implant may be relatively thin or not formed in the thickness of the reinforcement 115c.
도 6 및 도 7을 참조하여 일 실시예에 따른 의료용 보형물의 적용 방법과 그 기능을 설명한다. 도 6은 본 발명의 일 실시예에 따른 의료용 보형물이 적용된 모습을 나타내는 개략도이고, 도 7은 본 발명의 일 실시예에 따른 의료용 보형물의 외형을 개략적으로 나타내는 사시도이다.6 and 7 will be described a method and the function of applying the medical implant according to an embodiment. 6 is a schematic view showing a medical implant according to an embodiment of the present invention, Figure 7 is a perspective view schematically showing the appearance of the medical implant according to an embodiment of the present invention.

However, FIG. 6 and related descriptions are merely examples for convenience of description and are not limited to surgery of a woman's chest of the medical implant 100. That is, the medical implant according to the present invention can be applied to various parts of the human body through changes in size and shape in addition to the use for women's chest surgery. For example, it is possible to use the skin recessed portion and wrinkles, etc., and furthermore, it is possible to use for improving the volume sense of cosmetic purposes.
이와 같이 본 발명의 인체 내 삽입되는 의료용 보형물은 도 7에 도시된 바와 같이 인체 내 삽입되는 경우 주로 상부에 주름, 즉 리플링(Sh)이 형성된다. 그러나 본 발명에 따른 의료용 보형물(100)의 경우 바람직하게는 내측면 또는 내측면 상부측에 보강부를 형성함으로써 리플링(Sh)이 형성되는 것을 최소화시킬 수 있다.As such, the medical implant inserted into the human body of the present invention is mainly wrinkled, that is, rippled (Sh) is formed in the upper portion when inserted into the human body, as shown in FIG. However, in the case of the medical implant 100 according to the present invention, by forming a reinforcing part on the inner side or the upper side of the inner side, it is possible to minimize the formation of the ripple (Sh).
따라서 여성의 유방, 피부 함몰부 등에 삽입되는 경우에도 인체 내에서 식염수 등의 쏠림으로 인한 반대급부로서 상부에 주름이 형성되는 것을 방지할 수 있는 효과를 얻을 수 있다.Therefore, even when inserted into the female breast, skin depression, etc. can be obtained to prevent the formation of wrinkles in the upper portion as a counterpart due to the saline of the saline in the human body.
이상 본 발명의 바람직한 실시예에 대하여 설명하였으나, 본 발명의 기술적 사상이 상술한 바람직한 실시예에 한정되는 것은 아니며, 특허청구범위에 구체화된 본 발명의 기술적 사상을 벗어나지 않는 범주에서 다양하게 구현될 수 있다.Although the preferred embodiment of the present invention has been described above, the technical idea of the present invention is not limited to the above-described preferred embodiment, and may be variously implemented in a range without departing from the technical idea of the present invention specified in the claims. have.
