이하, 본 발명에 따른 골 신장기에 대해 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings for the bone expander according to the present invention will be described in detail.
먼저, 본 발명에 따른 골 신장기의 구성에 대해 설명한다. 도 1은 본 발명에 따른 골 신장기의 사시도이며, 이에 도시된 바와 같이, 본 발명에 따른 골 신장기는 크게 제1신장부(1), 수나사(2) 및 제2신장부(3)의 세부분으로 이루어져 있다. 이러한 골 신장기는 표피 내부에 삽입되는 내장형으로서 표피 내부에 삽입가능할 정도로 충분히 작은 크기인 것이 특징이다.First, the configuration of the bone expander according to the present invention will be described. 1 is a perspective view of a bone expander according to the present invention, as shown in this, the bone expander according to the present invention is largely divided into the first extension (1), male screw (2) and the second extension (3) Consists of Such bone stretcher is a visceral type inserted into the epidermis and is small enough to be inserted into the epidermis.
즉, 신장시킬 두 뼈를 임의로 제1뼈 및 제2뼈로 칭할 때, 제1신장부(1)는 제1뼈에 고정 설치되고, 제2신장부(2)는 제2뼈에 고정 설치되며, 제1신장부(1) 및 제2신장부(3)는 수나사(2)로 연결되어 있다.That is, when two bones to be stretched are arbitrarily referred to as a first bone and a second bone, the first kidney part 1 is fixedly installed on the first bone, and the second kidney part 2 is fixedly installed on the second bone, The first extension part 1 and the second extension part 3 are connected by a male screw 2.
제1신장부(1)의 바닥면에는 홀(4)이 형성되어 있고, 그 홀(4)을 관통하여 제1뼈에 설치되는 연결부재(5)를 이용하여 제1신장부(1)가 제1뼈에 고정되며 표피 내부에 삽입되도록 설치된다.A hole 4 is formed in the bottom surface of the first extension part 1, and the first extension part 1 is formed by using the connecting member 5 installed in the first bone through the hole 4. It is fixed to the first bone and is installed to be inserted into the epidermis.
제1신장부(1)의 몸체에는 체결홈이 형성되어 있고, 그 체결홈에는 수나사(2)가 관통되어 있다.A fastening groove is formed in the body of the first extension part 1, and a male screw 2 penetrates the fastening groove.
수나사(2)와 제2신장부(3)는 웜(6a) 및 웜홀(6b)로 이루어진 웜기어로 연결 설치되어 있다.The male screw 2 and the second extension part 3 are connected to a worm gear consisting of a worm 6a and a wormhole 6b.
즉, 수나사(2)의 제1신장부(1) 반대편 표면에는 웜홀(6b)이 설치되어 있고, 웜홀(6b)과 치합되는 웜(6a)은 제2신장부(3)의 몸체 내부에 내장되어 있다.That is, the worm hole 6b is provided on the surface opposite to the first extension part 1 of the male screw 2, and the worm 6a engaged with the worm hole 6b is embedded in the body of the second extension part 3. It is.
제2신장부(3)의 상부 표면에는 웜(6a)과 연결되어 웜(6a)을 작동하는 렌치홀(7)이 형성되어 있으며, 이러한 웜(6a) 및 웜홀(6b)로 이루어진 웜기어로 인해 수나사(2)의 수평회전력이 렌치홀(7)의 수직회전력으로 변환되는 것이다.The upper surface of the second extension portion 3 is formed with a wrench hole 7 connected to the worm 6a to operate the worm 6a. Due to the worm gear consisting of the worm 6a and the wormhole 6b, The horizontal rotational force of the male screw 2 is converted into the vertical rotational force of the wrench hole 7.
제2신장부(3)의 바닥면에는 홀(8)이 형성되어 있고, 그 홀(8)을 관통하여 제2뼈에 설치되는 연결부재(9)를 이용하여 제2신장부(3)가 제2뼈에 고정되며, 제2신장부(3)는 표피 내부에 삽입되도록 설치되고, 상면의 렌치홀(7)은 표피 외부와 연결되도록 되어있다.A hole 8 is formed in the bottom surface of the second extension part 3, and the second extension part 3 is formed by using the connecting member 9 installed in the second bone through the hole 8. It is fixed to the second bone, the second kidney portion 3 is installed to be inserted into the epidermis, the wrench hole 7 of the upper surface is to be connected to the outside of the epidermis.
이러한 골 신장기는 티타늄강으로 이루어져 그 무게가 가볍고 뼈를 지탱할 수 있을 정도의 강도를 유지하며, 내식성이 높아 인체에 해롭지 않다.The bone expander is made of titanium steel, its weight is light and maintains strength enough to support bones, and its corrosion resistance is not harmful to the human body.
다음, 상기한 바와 같은 구성으로 이루어진 골 신장기를 이용하여 뼈를 신장시키는 방법을 설명한다.Next, a method of extending the bone using the bone expander having the above configuration will be described.
먼저, 신장시킬 두 뼈를 임의로 제1뼈 및 제2뼈로 칭할 때, 그 중 제1뼈에 제1신장부(1)를 고정하기 위해 제1신장부(1)의 바닥면에 형성된 홀(4)을 관통하도록 연결부재(5)를 제1뼈에 설치한다.First, when the two bones to be stretched are arbitrarily referred to as the first bone and the second bone, a hole 4 formed in the bottom surface of the first extension part 1 to fix the first extension part 1 to the first bone thereof. The connecting member 5 is installed in the first bone so as to penetrate).
이 때, 제1뼈 및 제2뼈 사이의 간격보다 크고 제1신장부 및 제2신장부를 설치하는 공간을 제공하도록 제1신장부와 제2신장부 사이의 수나사 거리를 조절해 두는 것이 좋다.At this time, the male screw distance between the first kidney and the second kidney may be adjusted to provide a space for installing the first kidney and the second kidney, which is larger than the distance between the first bone and the second bone.
다음, 제2신장부(3)를 제2뼈에 고정하기 위해 하여 제2신장부(3)의 바닥면에 형성된 홀(8)을 관통하도록 연결부재(9)를 제2뼈에 설치한다.Next, in order to fix the second extension part 3 to the second bone, the connecting member 9 is installed in the second bone so as to pass through the hole 8 formed in the bottom surface of the second extension part 3.
다음, 표피 외부로부터 제2신장부(3)의 상부 표면에 형성된 렌치홀(7) 내로 렌치를 삽입하고 웜(6a) 및 웜(6a)과 치합된 웜홀(6b)을 회전하여 원하는 거리만큼 제1신장부(1) 및 제2신장부(3) 사이의 수나사(2) 거리를 신장시킨다. 이로써 제1뼈 및 제2뼈 사이의 거리를 신장시킬 수 있으며, 장기간의 치료기간 동안 치료계획에 맞는 거리만큼 렌치를 이용하여 수나사 거리를 신장시킴으로써 점차로 제1뼈 및 제2뼈 사이의 거리를 신장시킬 수 있다.Next, the wrench is inserted into the wrench hole 7 formed in the upper surface of the second extension part 3 from the outer surface of the epidermis, and the worm hole 6b engaged with the worm 6a and the worm 6a is rotated to a desired distance. The male screw 2 distance between the first extension part 1 and the second extension part 3 is extended. This can increase the distance between the first bone and the second bone, and gradually increase the distance between the first bone and the second bone by extending the male thread distance using a wrench as long as it fits the treatment plan for a long period of treatment. You can.
웜과 연결된 렌치는 신장이 끝난 후에는 피부 쪽에서 단순히 뽑기만 함으로서 신장기를 내부에 위치시키는 작용을 하며, 본 발명에 따른 골 신장기는 티타늄강으로 이루어져 있으므로 신장 후 제거를 위한 수술을 하지 않아도 된다. 이는 이미 개발된 점막을 통해 삽입하여 나중에 제거하는 수술을 다시 해야 하는 내부 신장기에 비해 다른 점이다.Wrench is connected to the worm after the end of the extension simply by pulling the skin from the side to the function of placing the extension inside, bone stretcher according to the present invention is made of titanium steel, so there is no need for surgery for removal after extension. This is different from the internal kidneys, which require insertion through the already developed mucosa and subsequent surgery to remove.
상기한 바와 같이, 본 발명에 따른 골 신장기는 인체의 표피 내부에 삽입되는 내장형이므로, 외관상 드러나지 않는 효과가 있으며, 따라서 장기간 동안 부착한 채로 생활하는 것이 종래의 골 신장기를 이용할 때보다 훨씬 쉬운 효과가 있다.As described above, since the bone expander according to the present invention is a built-in type that is inserted into the epidermis of the human body, there is an effect that does not appear in appearance, so it is much easier to live while attached for a long time than using a conventional bone stretcher have.
또한, 본 발명에 따른 골 신장기는 티타늄을 함유한 스테인레스 강으로 이루어져 그 무게가 가벼우므로 골 신장기를 부착한 환자들의 활동이 용이한 효과가 있으며, 내식성이 높아 인체에 해롭지 않으므로 골 신장기를 피부 표피 내에 내장한 환자의 부작용을 최소화하는 효과가 있다.In addition, the bone elongator according to the present invention is made of stainless steel containing titanium, so that the weight is light, so that the activity of the patients attached to the bone elongator is easy to effect, and because the corrosion resistance is not harmful to the human body, the bone elongator is in the skin epidermis. It has the effect of minimizing the side effects of internal organs.
특히, 본 발명에 따른 골 신장기는 티타늄강으로 이루어져 있으므로, 점막을 통해 삽입하여 나중에 제거하는 수술을 다시 해야 하는 기존의 내부 신장기와는 달리 신장 후 제거를 위한 수술을 하지 않아도 되는 효과가 있다.In particular, since the bone elongator according to the present invention is made of titanium steel, unlike the existing internal elongation machine that must be inserted again through the mucosa to remove the surgery later, there is no need to perform the surgery for removal after extension.
또한, 본 발명에 따른 골 신장기는 기존의 외부 신장기에서 사용되는 외부신장기와 뼈를 연결해주는 2개 이상의 나사못 이동이 없으므로, 신장 후 발생되는 피부 반흔에 의한 추형을 단지 렌치가 들어가는 부위만의 반흔으로 최소화 할 수 있다.In addition, the bone elongator according to the present invention does not have two or more screw movements connecting the external kidney and the bone used in the existing external elongator, so that the vertebrae caused by the skin scars generated after the extension are only scars of the portion where the wrench enters. It can be minimized.
또한 인체의 내부에 위치하는 내부 신장기와의 연결이 하나의 위치변동이 없는 렌치에 불과하므로 종래의 두 개 이상의 나사못에 의해 연결된 외부 신장기에 비해 피부를 통한 세균 감염의 기회를 크게 줄일 수 있는 효과가 있다. 이는 종래의 구강 점막을 통한 내부 신장기에 비해서도 동일한 효과를 나타내는데, 그 이유는 구강 내부에는 국소항생제의 도포가 불가능하나 피부에서는 멸균효과가 높은 연고제재를 사용함으로서 세균 감염의 기회를 막을 수 있기 때문이다.In addition, since the connection with the internal stretcher located inside the human body is only a wrench without a change in position, the effect of greatly reducing the chance of bacterial infection through the skin can be greatly reduced compared to the external stretcher connected by two or more conventional screws. have. This has the same effect as the internal kidney through the traditional oral mucosa, because it is impossible to apply topical antibiotics inside the oral cavity, but the use of ointment with high sterilization effect on the skin prevents the chance of bacterial infection. .
