Abstract

The present invention relates to a balloon used to make a space within the human body, which is formed by coating an elastomer onto a reticulated structure made from metal wire. The balloon can be used safely within the human body because the metal reticulated structure strengthens the pressure resistance, thereby minimizing the possibility of rupture during expansion, and makes relatively elaborate surgical operations possible because the metal reticulated structure itself shows on the X-ray monitor during operations and so makes it easy to ascertain the balloon's position, state of expansion and the like.

Description

인체 내에서 공동을 형성하기 위하여 사용되는 풍선Balloon used to form a cavity in the human body
본 발명은 인체 내에서 공동을 형성하기 위하여 사용되는 풍선에 관한 것이다. The present invention relates to a balloon used to form a cavity in the human body.
풍선을 사용하여 인체 내에서 공동을 형성하는 경우로는 좁아진 혈관이나 손상된 척추를 복원하는 경우 등을 들 수 있다. 이하에서, 척추압박골절복원술 중 풍선시술법의 시술과정을 통하여 더욱 구체적으로 설명한다. In the case of using a balloon to form a cavity in the human body, for example, to restore narrowed blood vessels or damaged spine. In the following, it will be described in more detail through the procedure of the balloon method of spinal compression bone restoration.
척추압박골절복원술 중 풍선시술법의 시술은, 먼저, 압박 굴절된 부위에 가늘고 긴 특수 튜브를 삽입하고, 이를 통해 풍선 카테터(도1, 100)를 넣어 풍선(110)을 팽창시켜 압박 굴절된 부위를 정상적인 높이만큼 들어올린 후, 풍선을 제거하고 골 시멘트로 벌어진 공간을 채우는 과정으로 이루어지는데, 상기에서 풍선(110)을 팽창시켜서 압박 굴절된 부위를 정상적인 높이만큼 들어올리는 과정은 뼈 내부에 공동을 형성하는 과정으로 달리 표현될 수 있다.In the procedure of balloon surgery during spinal compression surgery, first, a long special tube is inserted into the compression refracted portion, and a balloon catheter (FIG. 1, 100) is inserted therein to inflate the balloon 110 to compress the refracted portion. After lifting by the normal height, the process of removing the balloon and filling the space with bone cement, the process of inflating the balloon 110 to lift the pressure refracted portion by the normal height to form a cavity inside the bone The process can be expressed differently.
상기와 같이 공동을 형성하는 경우에는 풍선에 큰 압력이 가하여 진다. 그러므로, 도 2에 도시된 바와 같은 엘라스토머 단일구조의 풍선은 시술시 파열될 우려가 상존한다. 풍선이 파열되는 경우에는, 카테터의 금속소재의 탐침과 인체가 접촉되는 문제도 우려되지만, 파열된 풍선의 조각이 회수되지 못하고 뼈 속에 잔존될 염려가 있으며, 시술이 지연되어 환자의 고통을 증가시키는 문제도 야기될 수 있다. 따라서, 안전하게 척추압박골절 풍선시술을 시술하기 위해서는 상기와 같은 문제의 조속한 해결이 필요하다. In the case of forming a cavity as described above, great pressure is applied to the balloon. Therefore, there is a concern that the balloon of the elastomeric unitary structure as shown in FIG. 2 may burst during the procedure. If the balloon is ruptured, there is a concern that the catheter's metal probe and the human body may come into contact with each other, but there is a risk that the ruptured balloon may not be recovered and remain in the bone, and the procedure may be delayed to increase patient pain. Problems can also arise. Therefore, in order to safely perform a spine compression fracture balloon procedure, it is necessary to promptly solve the above problem.
한편, 척추압박골절 풍선시술시 체내의 풍선위치를 X-Ray로 확인하기 위해서는 카테터 내부에 백금으로된 마커가 장착되어 있어야 하고, 고가의 조영제를 주입해야만 한다. 그러나, 이러한 조건을 충족하더라도 모니터 상에서 풍선의 위치는 희미하게 판독될 뿐이므로, 정교한 시술을 위해서는 더 높은 해상도로 풍선의 위치나 형태를 파악할 수 있는 방법의 개발이 필요하다.On the other hand, during the spinal compression fracture balloon procedure to check the balloon position in the body by X-Ray, a marker of platinum must be mounted inside the catheter, and an expensive contrast agent must be injected. However, even if these conditions are met, the position of the balloon is dimly read on the monitor. Therefore, a sophisticated method requires the development of a method for determining the position or shape of the balloon at a higher resolution.
본 발명은, 종래기술의 상기와 같은 문제를 해결하기 위한 것으로서, The present invention is to solve the above problems of the prior art,
첫째, 내압강도를 향상시켜서 팽창시 파열가능성이 최소화되는 인체 내에서 공동을 형성하기 위하여 사용되는 풍선을 제공하는 것을 목적으로 한다.First, to provide a balloon used to form a cavity in the human body to improve the pressure resistance to minimize the possibility of rupture during expansion.
둘째, 백금으로된 마커 및 고가의 조영제를 사용하지 않고서도, 풍선의 위치 및 팽창형태 등의 모니터링이 가능한 인체 내에서 공동을 형성하기 위하여 사용되는 풍선을 제공하는 것을 목적으로 한다.Second, an object of the present invention is to provide a balloon used to form a cavity in the human body capable of monitoring the position and inflation type of the balloon without using a marker made of platinum and an expensive contrast agent.

또한, 금속 망상구조체 자체가 X-Ray 모니터상에 나타나기 때문에 풍선의 위치 및 팽창형태 등의 파악이 용이하여 보다 정교한 시술을 가능하게 한다. In addition, since the metal network itself appears on the X-ray monitor, it is easy to grasp the position and inflation type of the balloon, thereby enabling more sophisticated procedures.
또한, 풍선의 위치를 파악하기 위하여 별도로 백금으로된 마커 및 고가의 조영제를 사용할 필요가 없으므로 매우 경제적이다.In addition, since it is not necessary to use a separate platinum marker and expensive contrast agent to determine the location of the balloon is very economical.

본 발명은 금속와이어로 형성된 망상구조체에 엘라스토머를 코팅하여 성형된, 인체 내에서 공동을 형성하기 위하여 사용되는 풍선에 관한 것이다. The present invention relates to a balloon used to form a cavity in a human body, which is formed by coating an elastomer on a network structure formed of a metal wire.
상기 풍선은 좁아진 혈관이나 손상된 척추 등을 복원하는 경우에 사용되는 풍선 카테터 같은 기구에 사용된다. The balloon is used in an apparatus such as a balloon catheter, which is used to restore narrowed blood vessels or damaged vertebrae.

The network structure may be manufactured in various forms without particular limitation. For example, a method of cross-linking a plurality of metal wires and a method of braiding metal wires to form a knitted fabric may be mentioned.
그러나, 본 발명에서는 풍선의 팽창시 금속 망상구조체도 팽창되어야 하므로 금속와이어를 편조한 편물형태로 제조되는 것이 바람직하다. 왜냐하면, 금속와이어로 망상구조체를 편조할 때 루프(loop)와 루프(loop) 사이에, 풍선의 팽창시에 망상구조체의 팽창을 가능하게 하는 확장 여유분이 발생하므로 풍선의 팽창이 부드럽게 이루어질 수 있기 때문이다.However, in the present invention, since the metal network structure should also be expanded when the balloon is inflated, the metal wire is preferably manufactured in the form of a knitted fabric. This is because the expansion of the balloon can be made smoothly between the loop and the loop when braiding the network structure with metal wires, so that the expansion allowance of the network structure can be made when the balloon is inflated. to be.
상기에서 확장 여유분은 편조 방법에 의해 조절될 수도 있다.The expansion margin in the above may be adjusted by the braiding method.
상기에서 망상구조체는 편조하는 경우에 한 가닥의 금속와이어로 편조하거나 두 가닥 이상의 여러 가닥의 금속와이어로 편조하는 것도 가능하다. 그러나, 견고한 형태의 망상구조체를 제조하기 위해서는 한 가닥의 금속와이어로 편조하는 것이 바람직하다.When the network structure is braided, the network structure may be braided with one strand of metal wires or with two or more strands of metal wires. However, it is desirable to braid a single strand of metal wire to produce a rigid network structure.
본 발명에서 상기 금속와이어의 종류는 특별히 한정되지 않으나, 인체 내에서 사용하는 것이므로 스텐레스 등과 같이 의료용으로 적합한 소재를 사용하는 것이 바람직하다. Although the type of the metal wire in the present invention is not particularly limited, it is preferable to use a material suitable for medical use such as stainless steel because it is used in the human body.
본 발명에서 상기 엘라스토머로는 풍선의 신축을 원활하게 하는 것이라면 특별히 한정되지 않으나, 인체 내에서 사용하는 것이므로 폴리우레탄계 엘라스토머 등과 같이 의료용으로 적합한 소재를 사용하는 것이 바람직하다. In the present invention, the elastomer is not particularly limited as long as it facilitates the expansion and contraction of the balloon, but it is preferable to use a material suitable for medical use, such as a polyurethane-based elastomer, since it is used in the human body.
본 발명의 인체 내에서 공동을 형성하기 위하여 사용되는 풍선은 다양한 분양에서 응용될 수 있다. 예컨대, 척추압박골절 풍선시술시 사용되는 풍선 카테터 등에서 매우 유용하게 사용될 수 있다. The balloon used to form the cavity in the human body of the present invention may be applied in various forms. For example, it can be very useful in a balloon catheter used in a balloon compression fracture surgery.

The method for producing the balloon of the present invention is not particularly limited. For example, reference may be made to known processes for the manufacture of hoses comprising network structures, and the balloon of the present invention may be readily manufactured by adding a process of forming a balloon in addition to such a process.
예컨대, 압출장치를 사용하여 압출기에서 공급되는 엘라스토머 용액을, 압출금형의 중앙에 설치된 맨드릴을 따라 이송되는 미리 제조된 망상구조체에 피복하여관형태로 압출하고, 이를 공지의 방법에 따라 성형틀을 사용하여 성형하여 풍선형태로 제조할 수 있다.For example, using an extrusion apparatus, the elastomer solution supplied from the extruder is coated on a prefabricated network which is transported along a mandrel installed at the center of the extrusion mold and extruded into a tubular shape, which is then used in a mold according to a known method. It can be molded into a balloon form.
