Description

골절된 뼈의 회전와 이탈방지 기능을 갖는 골수 강 내 금속 정 고정용 지지체A support for fixing a metal chisel in the bone marrow cavity with a function to prevent rotation and separation of fractured bones
본 발명은 골절된 뼈의 회전와 이탈방지 기능을 갖는 골수 강 내 금속 정 고정용 지지체에 관한 것으로서, 보다 상세하게는 형상기억합금으로 된 고정용 지지체를 상온 상의 금속정에 끼워 넣어 사용자가 원하는 위치에 위치시킨 후 상기 고정용 지지체에 열을 가하게 되면 상기 고정용 지지체가 수축되면서 강한 고정력을 가지게 된 상태의 금속정을 골수강 내에 삽입하여 골절 부위를 고정하도록 한 골절된 뼈의 회전와 이탈방지 기능을 갖는 골수 강 내 금속 정 고정용 지지체에 관한 것이다. The present invention relates to a support for fixing a metal nail in the bone marrow cavity having a function of preventing rotation and separation of a fractured bone, and more particularly, by inserting a fixing support made of a shape memory alloy into a metal nail at room temperature at a user's desired position. When heat is applied to the fixing support after positioning, the fixing support contracts and a metal nail with strong fixing force is inserted into the intramedullary cavity to fix the fractured bone. It relates to a support for fixing a metal nail in the intramedullary cavity.
일반적으로 골절된 뼈를 접합시키기 위해 널리 사용되고 있는 내고정장치 들은 관절이 굳는 것을 막아주고 골절의 치유도 촉진시켜 준다.In general, internal fixation devices, which are widely used to join fractured bones, prevent joints from hardening and promote healing of fractures.
그러나 골절이 완치되어 골절판을 제거하고 나면, 골절판과 접촉한 부위의 뼈가 다시 부러지는 재골절(Refracture)현상이 나타나게 된다.However, after the fracture is cured and the fracture plate is removed, a re-fracture phenomenon occurs, in which the bone in contact with the fracture plate is broken again.
일반적인 골절 치료방법들을 살펴 보면 다음과 같다. 도 1에 도시된 바와 같이, 수술을 하지 않고 치료하는 비수술 치료장치로서, 골절된 뼈(1a, 1b)의 외부로 감싸는 석고붕대(2)를 사용하는 장치이다.Common fracture treatment methods are as follows. As shown in Figure 1, as a non-surgical treatment device for treatment without surgery, it is a device using a plaster bandage (2) wrapped around the outside of the fractured bones (1a, 1b).
이러한 방법은 골절된 상태의 뼈를 직접적으로 지지할 수 없는 간접적인 방법이므로 골절치료에는 한계가 있다.Since this method is an indirect method that cannot directly support the bone in a fractured state, there is a limit to the treatment of fractures.
도 2는 골절된 뼈(1a, 1b)의 내부로 금속정(Intramedullary Nail)(3)을 삽입하여 치료하는 장치로서, 이때 사용되는 금속정(3)은 장골의 단순골절에만 적용될 수 있기 때문에 적용할 수 있는 치료의 범위가좁은 문제점이 있다.2 is a device for treatment by inserting an intramedullary nail (3) into the fractured bones (1a, 1b), and the metal nail (3) used in this case can be applied only to simple fractures of the long bones. There is a problem that the range of treatment that can be done is narrow.
또한, 도 3은 금속판으로 된 골절판(4)과 나사(5)를 이용한 것으로서, 도시된 바와같이 다수개의 나사(5)를 뼈에 삽입하여 골절된 뼈(1a, 1b)의 양측에 걸쳐 골절판(4)을 결착하는 방법으로, 가장 널리 사용되며 치료의 응용범위가 또한 넓은 방법이다.In addition, Figure 3 uses a fracture plate 4 and a screw 5 made of a metal plate, and as shown in the figure, a plurality of screws 5 are inserted into the bone to cross both sides of the fractured bones 1a and 1b. As a method of binding the out-of-print plate (4), it is the most widely used and has a wide range of therapeutic applications.
그러나 상기 골절판(4)과 나사(5)를 이용한 방법은 골절치료가 끝난 후에는 골절의 접합부(6) 근처에서 뼈에 작은 구멍들이 생기는 골다공증 현상이 발생하게 되는 문제점이 있었다. 이러한 골다공증 현상이 발생하는 주요 원인의 하나는 금속으로 된 골절판(4)의 지나친 강성 때문이다.However, the method using the fracture plate 4 and the screw 5 has a problem in that, after the fracture treatment is finished, osteoporosis in which small holes are formed in the bone near the junction 6 of the fracture occurs. One of the main causes of such osteoporosis is the excessive rigidity of the fracture plate 4 made of metal.
즉, 골절판(4)의 강도가 뼈에 비해서 약 10배 정도 크기 때문에 대부분의 생리하중(Physiological Load)이 골절판(4)으로 전달되고, 골절부위의 뼈(1a, 1b)에는 거의 전달되지 않게 된다.In other words, since the strength of the fracture plate 4 is about 10 times greater than that of the bone, most of the physiological load is transmitted to the fracture plate 4, and hardly transmitted to the bones 1a and 1b at the fracture site. will not
이와 같이, 뼈가 하중을 받지 못하는 응력차폐(Stress shield)현상으로 인해 하중을 받지 못하는 부위에서 골 흡수 작용이 왕성하게 일어나게 되어 뼈에 작은 구멍들이 생기게 된다. 이러한 현상으로 인해 뼈의 강도가 현저히 저하되어 재골절이 초래되는 것이다. In this way, due to the stress shield phenomenon in which the bone does not receive a load, bone resorption occurs vigorously in the region where the load does not receive it, and thus small holes are formed in the bone. Due to this phenomenon, the strength of the bone is significantly reduced, resulting in re-fracture.
따라서, 골절판(4) 제거 수술을 한 후에는 일정기간 동안 목발과 같은 보조기구를 이용해야 하는 불편을 겪게 되고, 또한, 보행등의 운동에 의해 발생하는 충격하중이 전달되는 경우에는, 충격흡수 능력이 부족하여 충격파에 의한 가골 손상이 일어나게 되어 골절치유를 어렵게 만들 뿐만 아니라 골절판(4)도 부러지기 쉬운 문제점이 있다.Therefore, after surgery to remove the fracture plate 4, it is inconvenient to use an auxiliary device such as crutches for a certain period of time. Also, when the shock load generated by movement such as walking is transmitted, shock absorption The lack of ability causes callus damage caused by shock waves, which not only makes it difficult to heal a fracture, but also has a problem that the fracture plate 4 is easy to break.
특히, 도 2의 경우 금속정을 사용하는 경우 시술 후 골절 부와의 결속력이 약해져서 회전되는 일이 빈번하게 발생하였다.In particular, in the case of FIG. 2, when a metal tablet is used, the binding force with the fractured part is weakened after the procedure, and rotation occurs frequently.
따라서, 본 발명은 상술한 바와 같은 종래의 제반 문제점들을 해소하기 위하여 창안된 것으로서, 골절부를 고정하기 위한 금속정에 설치되어 상기 골절부를 고정과 강도를 보장하고, 뼈의 회전을 방지하도록 한 골절된 뼈의 회전와 이탈방지 기능을 갖는 골수 강 내 금속 정 고정용 지지체를 제안하게 되었다.Therefore, the present invention was devised to solve the problems of the prior art as described above, and is installed on a metal chisel for fixing the fractured part to ensure the fixation and strength of the fractured part, and to prevent the rotation of the bone. A support for fixing a metal chisel in the bone marrow cavity with a function of preventing bone rotation and separation was proposed.
