본 발명은 척추 치료용 풍선 카테터(catheter)에 관한 것으로서, 특히 치료에 소요되는 시간이 줄어들고 주입된 골시멘트가 급결되면서 신경을 자극하고 파괴하는 것을 방지하는 풍선 카테터 및 이를 이용한 치료방법에 관한 발명이다.The present invention relates to a balloon catheter for spinal treatment, and more particularly, to a balloon catheter and a method of treatment using the same, which reduce the time required for treatment and prevent the stimulation and destruction of nerves as the injected bone cement is rapidly frozen. .

주지된 바와 같이 인간이나 동물의 뼈는 단백질, 콜라겐 및 칼슘염을 함유한 골격으로 이루어지는 바, 잦은 음주와 흡연 또는 약물복용 등으로 인해 골다공증이 발생하고, 유방암 및 골 전이 등이 발생하는 경우에는 뼈가 쉽게 골절되거나 약해져 골절 또는 압박골절이 발생하게 된다.As is well known, the bones of humans or animals are composed of a skeleton containing protein, collagen, and calcium salts. In the case of osteoporosis due to frequent drinking, smoking, or drug use, and in the case of breast cancer and bone metastasis, bones Is easily fractured or weakened, causing fractures or compression fractures.

따라서, 뼈의 무너짐으로 인해 신경이 눌러져 심한 고통이 가해져 생활이 어렵게 만들며, 심한 경우에는 신체의 마비가 발생하기도 한다.Therefore, due to the collapse of the bones, the nerves are pressed and severe pain is applied, making life difficult, and in severe cases, paralysis of the body may occur.

이러한 골절이나 압박골절로 인한 척추를 보강하기 위해 최근에는 풍선 카테터를 이용하여 치료를 하기도 하는 바, 일반적으로 카테터(catheter)는 카테테르라고도 하는 것으로서 관 형태의 기구를 말하며, 보통 합성수지, 플라스틱 고무, 라텍스, 실리콘, 금속 등의 재질로 이루어진다.Recently, a balloon catheter is used to reinforce the spine due to such fractures or compression fractures. In general, a catheter, also called a catheter, refers to a tubular device. It is made of a material such as latex, silicon, metal.

이하, 본 발명의 가장 바람직한 일 실시예의 구성을 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration of the most preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 8은 본 발명에 따른 풍선 카테터의 분리 사시도이고, 도 9는 본 발명에 따른 풍선 카테터의 주입관과 확장부의 체결상태를 확대 도시한 일부 예시도이고, 도 10은 본 발명에 따른 풍선 카테터를 척추의 삽입구에 삽입한 상태의 예시 단면도이다. 또한, 도 11은 본 발명에 따른 풍선 카테터에 골시멘트를 주입하는 상태를 도시한 예시 단면도이며, 도 12는 본 발명에 따른 풍선 카테터에 의해 골시멘트가 확장부에 주입된 상태에서 급결되어 척추를 보강한 상태의 예시 단면도이며, 도 13은 본 발명에 따른 풍선 카테터에 의해 척추를 보강하는 순서를 도시한 순서도이다.Figure 8 is an exploded perspective view of the balloon catheter according to the present invention, Figure 9 is an exemplary view showing an enlarged expansion state of the injection tube and the expansion of the balloon catheter according to the present invention, Figure 10 is a balloon catheter according to the present invention It is sectional drawing of the state inserted in the insertion opening of a spine. In addition, Figure 11 is an exemplary cross-sectional view showing a state of injecting bone cement into the balloon catheter according to the present invention, Figure 12 is fastened in the state in which the bone cement is injected into the expansion by the balloon catheter according to the present invention spine Exemplary cross-sectional view of the reinforced state, Figure 13 is a flow chart showing a procedure for reinforcing the spine by the balloon catheter according to the present invention.

본 발명의 척추 치료용 풍선 카테터는 SUS(STEEL UNSTAIN) 등의 소재로 되는 긴 관 형태의 골시멘트 주입관(100)과, 상기 골시멘트 주입관(100)과 체결구(300)에 의해 체결되는 대략 8자 형태의 고무재질로 되는 풍선 확장부(200)로 이루어진다.The balloon catheter for spinal treatment of the present invention is fastened by a long tube-shaped bone cement infusion tube 100 made of a material such as SUS (STEEL UNSTAIN), and the bone cement infusion tube 100 and the fastener 300 It consists of a balloon expansion portion 200 made of a rubber material of approximately eight characters.

즉, 상기 골시멘트 주입관(100)의 끝단에 나사 등의 체결구(300a)를 형성하고, 풍선 확장부(200)의 일측 끝단에도 상기 골시멘트 주입관(100)과 대접되는 형태의 체결구(300b)를 형성하여 서로 조립 및 분해가 가능하도록 한다.That is, a fastener 300a such as a screw is formed at the end of the bone cement infusion tube 100, and a fastener having a form in which one side end of the balloon expansion part 200 is in contact with the bone cement infusion tube 100. 300b is formed to be assembled and disassembled with each other.

물론, 상기 체결구(300)는 본 발명에서 기재하지 않은 다양한 형태의 체결구를 적용할 수 있는 것은 당연하다.Of course, the fastener 300 is naturally applicable to various types of fasteners not described in the present invention.

또한, 상기 풍선 확장부(200)의 내측에는 골시멘트 주입관(100)과 연통되도록 풍선 확장부(200)의 체결구(300b) 측에서 풍선 확장부(200)의 내부를 가로질러 소정 직경의 연장관(400)이 구비되며, 상기 연장관(400)에는 하나 이상의 토출구(410)가 형성된다.In addition, the inside of the balloon expansion portion 200 in a predetermined diameter across the inside of the balloon expansion portion 200 at the fastener 300b side of the balloon expansion portion 200 so as to communicate with the bone cement injection tube 100. Extension tube 400 is provided, the extension tube 400 is formed with one or more discharge port 410.

따라서, 상기와 같이 구성되는 본 발명의 풍선 카테터를 이용하여 척추를 치료하기 위해 먼저 공지와 마찬가지로 드릴(30) 등의 공구로 치료를 하고자 하는 척추 부분에 소정의 깊이만큼 삽입구(40)를 형성한다.(S110)Therefore, in order to treat the spine using the balloon catheter of the present invention configured as described above, the insertion hole 40 is formed to a predetermined depth in the spinal part to be treated with a tool such as a drill 30 as in the prior art. (S110)

그리고, 풍선 카테터의 풍선 확장부(200)를 척추에 형성된 삽입구(40)에 삽입하고(S120), 골시멘트 주입관(100)을 통해 급결 골시멘트(60)를 고압으로 주입한다.(S130) Then, the balloon expansion portion 200 of the balloon catheter is inserted into the insertion hole 40 formed in the spine (S120), and the fastening bone cement 60 is injected at a high pressure through the bone cement injection tube 100 (S130).

주입되는 골시멘트(60)가 풍선 확장부(200)의 연장관(400)에 형성된 토출구(410)를 통해 풍선 확장부(200) 내로 토출되면서 풍선 확장부(200) 내에 충진되고, 과충진이 되면 주입된 골시멘트(60)가 풍선 확장부(200)를 확장시키면서 충진 된다.When the injected bone cement 60 is filled into the balloon expansion part 200 while being discharged into the balloon expansion part 200 through the discharge hole 410 formed in the extension pipe 400 of the balloon expansion part 200, The injected bone cement 60 is filled while expanding the balloon extension 200.

따라서, 무너진 척추 부분이 점차 세워지면서 보강이 되고, 주입된 골시멘트(60)는 풍선 확장부(200)와 함께 척추 내부에서 급결되어 굳어지면, 상기 풍선 확장부(200)와 연장관(400)을 골시멘트 주입관(100)으로부터 체결구(300)에 의해 분리하고 주입관(100)을 인출한다(S140).Therefore, the collapsed spine portion is gradually reinforced to be reinforced, and the injected bone cement 60 is fastened and hardened inside the spine together with the balloon extension part 200, thereby expanding the balloon extension part 200 and the extension pipe 400. The bone cement injection tube 100 is separated by the fastener 300 and withdraws the injection tube 100 (S140).

즉, 척추 내부를 세우기 위해 주입하는 골시멘트(60)가 풍선 확장부(200) 내에서 급결됨에 따라, 급결되면서 발생하는 열이 풍선 확장부(200)의 차단에 의해 척추의 신경에 직접 접하지 않게 되고, 주입된 골시멘트(60)가 신경을 자극할 염려도 없기 때문에 시술에 따른 통증이 발생할 염려가 줄어든다.That is, as the bone cement 60 injected to build up the inside of the spine is rapidly fastened in the balloon extension 200, heat generated while being fastened does not directly contact the nerves of the spine by blocking the balloon extension 200. Since the bone cement 60 is not injected, there is no fear of irritating the nerves, so there is less concern about the pain caused by the procedure.

이렇게 본 발명의 척추 치료용 풍선 카테터는 풍선 확장부(200)를 확장하기 위한 확장가스 또는 확장액(50)을 별도로 주입하는 단계를 수행하지 않고 척추 내부에 소정의 공간을 확보하게 되며, 풍선 확장부(200)를 확장시키기 위한 장비와 골시멘트(60)를 주입하기 위한 장비를 별도로 구비할 필요가 없기 때문에 시술이 간단하고 시간이 절감되게 된다.Thus, the balloon catheter for spinal treatment of the present invention secures a predetermined space inside the spine without performing the step of separately injecting the expansion gas or the expansion liquid 50 for expanding the balloon expansion part 200, and expanding the balloon. Since the equipment for expanding the portion 200 and the equipment for injecting the bone cement 60 need not be provided separately, the procedure is simple and the time is saved.

본 발명은 상기와 같이 별도의 확장 에어 또는 확장액을 주입하지 않고 골시 멘트를 주입하면서 풍선 확장부를 확장함에 따라 작업단계가 획기적으로 줄어 시술시간이 줄어 들고, 주입한 골시멘트가 급결되면서 발생하는 열을 풍선 확장부가 차단해 줌에 따라 신경이 파괴될 염려도 없는 매우 유용한 발명이다.According to the present invention, as the balloon expansion unit is expanded while injecting bone cement without injecting the expansion air or the expansion liquid as described above, the operation time is drastically reduced, the procedure time is reduced, and the heat generated while the injected bone cement is rapidly frozen. It is a very useful invention that does not have to worry about nerve breakdown as the balloon extension blocks.
