Description

절골술 및 골절치료용 금속판{angleostectomy and Metal plate for fracture cure}Angleostectomy and Metal plate for fracture cure}

본 발명은 절골술 및 골절치료용 금속판에 관한 것으로, 더욱 상세하게는 시술 이후 피시술자의 신체적인 특성 및 절골술에 의해 변경된 형상에 대응하게 각도가 조절되는 절골술 및 골절치료용 금속판에 관한 것이다.The present invention relates to a metal plate for osteotomy and fracture treatment, and more particularly, to an osteotomy and fracture treatment metal plate whose angle is adjusted to correspond to the physical characteristics of the subject and the shape changed by osteotomy.

주지하다시피, 골절치료용 금속판은 인체 사지의 뼈가 외상에 의하여 손상되어 있는 경우 가장 광범위하게 사용되고 있다. 이때, 관절 주위 골절은 뼈가 뭉툭하게 튀어나와 정확하게 뼈를 맞추어야 관절이 움직일 수 있다.As is well known, the fracture plate is most widely used when the bones of the limbs are damaged by trauma. At this time, the fracture around the joint is blunt protruding and the bones must be precisely aligned so that the joint can move.

도 1은 종래 골절치료용 금속판을 설명하기 위한 구성도이다.1 is a block diagram illustrating a conventional metal plate for fracture treatment.

도 1을 참조하면, 종래 골절치료용 금속판(100)은 직선형으로 구성되며, 다수의 관통홀(110)에 나사를 삽입함으로써 뼈를 고정하고 골절을 유합한다.Referring to FIG. 1, the conventional fracture treating metal plate 100 is configured in a straight shape, and fixes bones by inserting screws into a plurality of through holes 110 and fuses fractures.

하지만, 종래 골절치료용 금속판은 신체적인 특성에 따라 조금씩 특정 각도로 굴곡되어 있는 뼈의 형상에 의해 시술시 금속판이 뼈의 위나 아래로 조금씩 튀 어 나오게 된다. 이때, 뼈의 형상은 개인의 신체적인 특성에 따라 저마다 조금씩 다른 경사각을 가지게 되어 그 차이가 크지 않다고 할 수 있지만 미세한 차이라도 피시술자는 상당한 차이를 느끼게 되어 적응기간이 오래 소요될 우려가 있다.However, in the conventional fracture treatment metal plate, the metal plate protrudes little by little above or below the bone during the procedure by the shape of the bone bent at a specific angle little by little depending on physical characteristics. At this time, the shape of the bone has a slightly different angle of inclination depending on the physical characteristics of the individual can be said that the difference is not large, but even a small difference there is a possibility that the subject feels a considerable difference and it takes a long time to adapt.

또한, 종래의 직선형 금속판은 별도의 장치를 통해 피시술자에게 적합하도록 미세하게 각도를 부여한 후 시술이 이루어지기도 하는데, 이는 시간낭비와 함께 금속판을 강제로 구부림에 따라 금속판이 미세하게 파손되는 문제점이 있다.In addition, the conventional straight metal plate may be performed after giving a fine angle so as to be suitable for the subject through a separate device, which is a problem that the metal plate is finely damaged as the metal plate is forcibly bent with time wasting.

한편, 근래에는 그 일단을 소정각도로 절곡한 골절치료용 금속판이 제안된 바 있다. 이와 같은 골절치료용 금속판은 관절부위 뼈 형태에 대응하도록 절곡부를 형성한 것인데, 이렇게 절곡부를 형성한 골절치료용 금속판은 전술한 바와 같이 피시술자 개인의 신체적인 특성에 따라 뼈의 형상이 조금씩 다른 경사각을 갖게 되므로 기존의 문제점이 여전히 상존한다. On the other hand, in recent years there has been proposed a metal plate for fracture treatment bent at a predetermined angle. Such a metal plate for treating fractures is formed by bending portions to correspond to the shape of the joints. As described above, the metal plate for treating fractures may have different angles of inclination depending on the physical characteristics of the individual. As a result, existing problems still exist.

또한, 절골술용 금속판은 시술할 때 절골술 후 대퇴골 경부와 대퇴골 장축과의 각도변화를 사전에 정확히 예측하는 것이 어렵고, 대퇴골두로 삽입되는 스크류의 위치가 매우 중요하기 때문에 절골 전에 삽입한 다음, 절골술을 시행해야되는 데 아직 기존의 제품으로는 이러한 시술방법으로 접근이 불가능하였다.In addition, it is difficult to accurately predict the angle change between the femur neck and the femur long axis before the osteotomy, and because the position of the screw inserted into the femoral head is very important, the osteotomy plate is inserted before the osteotomy. However, it is not yet possible to access this product with existing methods.

이에, 본 발명은 기존 절골술 및 골절치료용 금속판이 갖는 제반적인 문제점을 해결하기 위해 창안된 것으로,Accordingly, the present invention was made to solve the general problems of the existing osteotomy and fracture treatment metal plate,

본 발명이 해결하고자 하는 과제는 피시술자의 신체적인 특성과 절골술 전 후 각도변화 및 형상변화에 대응하기 위해서 각도가 조절될 수 있는 골절치료용 금속판을 제공하는 데 있다.The problem to be solved by the present invention is to provide a metal plate for fracture treatment that can be adjusted angle to correspond to the physical characteristics of the subject and the angle change and shape change before and after osteotomy.
