Abstract

A rigid stepped plate is provided to shorten a recovery time and improve a convenience of an operation by obtaining a large fixing force with a minimum incision. A rigid stepped plate includes a body, a metal screw(11), and a plurality of screw holes. The body is formed to have a step shape by connecting a vertical plane of a plurality of trapezoid plates with a planar plane of a plurality of trapezoid plates. The metal screw(11) is installed on a corner of a horizontal part. The plurality of screw holes are installed on planar plates(13,14) and a vertical plate(12). The metal screw(11) is installed on a corner of the planar plates(13,14) so that a linear line of a length direction of the metal screw(11) is a perpendicular line of the planar plates(13,14). The opposite corner of the part connected with the planar plates(13,14) is formed to have a conical shape. The corner of the plate connected to the metal screw has a curvature.

절골술의 고정 방법으로는 석고 고정 만을 시행하는 방법에서 Coventry staple, angled blade plate, 외고정 장치까지 여러 가지가 있다. 본 발명과 가장 유사한 관련된 특허 등록 10-0155605-0000 에 제안된 발명에서는 뾰족한 긴다리와 짧은 다리를 구비하고 상기 두 다리를 굴곡 연결하는 연결부를 구비한 고정핀과, 상기 긴다리와 짧은 다리를 수용가능하고 나사 고정을 위한 카운터 싱크를 구비하고 중심부에 홈이 두개의 구멍을 구비하여 수술후에도 석고고정이 필요없으며, 수술직후부터 관절운동이 가능하며, 수술 후 약 3주부터는 목발보행이 가능하고, 재활치료를 위한 재입원이 필요하지 않다는 효과가 있는 미니플레이트 스테이플을 제안하고 있으며 본 발명은 퇴행성 관절염 등 기타의 원인에 의한 무릎의 내반변형에 대하여 경골을 절골하여 약간 외반각을 이루도록 교정해 주는 경골 근위부 절골술에 있어 절골부위의 정확한 시술을 도모하고 안전하고 효과적인 고정방법을 통해 수술 후 조기에 무릎의 운동이 가능하고 골 유압을 촉진시키는데 목적이 있다. 이를 실현하기 위해 본 발명은 지지대가 결합된 상 절골인도판과 상하·회전운동으로 절골모양을 설정해 주는 하 절골인도판으로 구성된 경골 절골인도장치를 이용하여 개인적 변이가 많은 경골 모양과 크기에 관계없이 정확한 절골이 될 수 있도록 하고, 절골된 경골의 근위부와 원위부에 특수한 기능의 나사못을 삽입하고, 이 나사못에 케이블과 인장고리를 이용하여 안전하고 효과적인 절골부위의 고정을 이루도록 하고 있다. 그러나 장기간의 고정으로 인한 관절 강직 및 관절 연골의 퇴화와 같은 부작용을 방지하기 위해 견고한 고정을 얻어 조기에 관절 운동을 가능하도록 하는 것이 바람직하지만 기존의 고정물들은 만족스럽지 못하였으며, 그 동안 수많은 내고정 기기가 개발되었던 것은 역설적으로 만족스러운 내고정 기기가 없었다는 반증이기도 하다. 본 발명은 위와 같은 스테이플 기능이 없는 일반 고정 플레이트가 아닌 스테이플 기능을 구비하며 또한 절골부의 고정에 적합한 디자인을 가진 미니플레이트 스테이플에 관한 것으로서, 특히 경골근위부 절골술에 사용하는 것으로서, 종래의 스테이플에 비해 6배 이상의 강력한 고정력을 나타내는 경골근위부 절골술에 사용하는 미니플레이트 스테이플에 관한 것이다.There are various methods of fixation of osteotomy, such as plaster fixation only, coventry staple, angled blade plate, external fixator. The invention proposed in the related patent registration 10-0155605-0000 which is most similar to the present invention includes a fixing pin having a pointed long leg and a short leg and a connecting portion for bending the two legs, and receiving the long leg and the short leg. It has a countersink for screw fixation and two holes in the center, so it doesn't need gypsum fixation after surgery, joint movement is possible right after surgery, and crutches can be walked about 3 weeks after surgery. A miniplate staple is proposed that does not require re-entry for rehabilitation treatment. The present invention provides a tibial osteotomy for correcting the valgus of the knee due to degenerative arthritis and other causes. In the proximal osteotomy, the accurate operation of the osteotomy site and the safe and effective fixation method Sikineunde early postoperative possible motion of the knee and to promote bone hydraulic aims. In order to realize this, the present invention uses a tibial osteotomy guide device composed of an upper osteotomy guide plate combined with a support and a lower osteotomy guide plate to set up the osteotomy in up and down rotational motion, regardless of the shape and size of the tibia. In order to ensure accurate osteotomy, a special function screw is inserted into the proximal and distal portions of the osteotomized bone, and a secured and effective fixation of the osteotomy site is achieved by using a cable and a tension ring. However, in order to prevent side effects such as joint stiffness and degeneration of articular cartilage due to prolonged fixation, it is desirable to obtain a firm fixation to enable joint movement early, but existing fixtures are not satisfactory. What was developed was paradoxically that there was no satisfactory internal fixation. The present invention relates to a miniplate staple having a staple function and a design suitable for fixation of an osteotomy, rather than a general fixation plate without the staple function as described above, in particular for use in proximal tibial osteotomy, 6 The present invention relates to a miniplate staple for use in proximal tibial osteotomy showing a strong fixation force of more than twice.

경골 근위부 절골술은 슬관절 골관절염의 수술적 치료 방법의 하나로서 그 자체로서도 매우 효과적인 치료 방법이며, 인공 슬관절 치환술의 시행 시기를 지연시킬 수 있는 치료 방법으로 인정 받고 있다. 이러한 경골 근위부 절골술의 성공을 위해서는 적절한 환자의 선택, 수술 전 계획 및 정확한 수술 술기, 재활 치료가 모두 필수적이다. 본 고안은 경골 근위부 절골술 시에 적은 절개와 연부 조직 박리로도 견고한 고정을 얻기위해 고안되었다. Tibial proximal osteotomy is one of the most effective methods of surgical treatment of osteoarthritis of the knee, and it is recognized as a treatment method that can delay the timing of artificial knee arthroplasty. For the success of the proximal tibial osteotomy, proper patient selection, preoperative planning and accurate surgical techniques, and rehabilitation are essential. The present invention was designed to obtain a firm fixation with small incisions and soft tissue detachment during proximal tibial osteotomy.

계단형 경골 상부 내고정물 집게 (plate holder)로 계단형 경골 상부 내고정물을 잡고 절골부가 닫혀 절골면이 접촉하도록 유지하고, 망치 (mallet) 로 가격하여 근위 2개의 금속정(1, 11, 21, 31)은 근위 골편에, 원위 1개의 금속정(1, 11, 21, 31)은 원위 골편에 한다. 근위부 금속정이 어느 정도 삽입되어, 원위부의 금속정이 삽입될 부위가 결정되면 드릴을 이용하여 피질골에 구멍을 내고 그 구멍을 통하여 원위 금속정이 삽입되도록 한다. 일단 금속정을 통해서 절골 부위가 고정이 되면, 5.0mm cannulated screw를 나사 삽입 구멍(5, 22) 에 근위부와 원위부에 각각 2개씩 고정한다. 이때 근위부와 원위부의 위치상 차이에 맞도록 상판(13, 4)과 하판(14, 3)사이의 높이차가 형성이 되어 있다. 경골의 작은 절개로 과도한 연부 조직손상을 방지할 수 있도록 하는 계단형태의 몸체와 경골에 몸체를 고정할 수 있도록하는 금속정 및 견고한 고정을 위해 나사를 삽입할 수 있는 나사구멍을 구비한 것을 특징으로 한다. 또한 계단형태의 몸체는 골편 상부 절제시 변형되는 골두부와 골체 사이의 횡축 길이차이에 따라 계단부의 높이를 선택할 수 있으며,금속정과 나사구멍에 나사를 이용하여 경골을 고정할 수 있는 것을 특징으로 하며, 금속정은 경골 근위부 절골술시에 절제된 경골부의 고정을 돕고, 경골을 견고히 고정을 할 수 있도록 하는 나사를 경골에 삽입할 수 있는 구멍의 위치를 원활히 확보하도록 하는 것을 특징으로 하고, 나사구멍은 나사못이 다양한 각도로 삽입될 시, 나사와 계단형 경골 상부 내고정장치가 밀착할 수 있도록 나사머리와 나사구멍이 접하는 면이 원형처리 되어 있는 것을 특징으로 하는 계단형 경골 상부 내고정물이다.  Hold the stabilized tibial upper fixation with a plate holder and hold the osteotomy with the osteotomy closed, and hit the mallet with a mallet to strike the two proximal nails (1, 11, 21, 31) in the proximal bone fragment and one distal nail (1, 11, 21, 31) in the distal bone fragment. When the proximal metal tablet is inserted to some extent, and the site where the distal metal tablet is inserted is determined, a hole is used to drill the cortical bone and the distal metal tablet is inserted through the hole. Once the osteotomy is secured through the metal nail, secure two 5.0 mm cannulated screws in the proximal and distal ends of the screw insertion holes (5, 22). At this time, the height difference between the upper plate 13, 4 and the lower plate 14, 3 is formed so as to match the positional difference between the proximal portion and the distal portion. Stepped body to prevent excessive soft tissue damage due to small incision of the tibia, metal nail to secure the body to the tibia and screw holes for inserting screws for firm fixation do. In addition, the step-shaped body can select the height of the step according to the transverse length difference between the head and the bone to be deformed when the upper section of the bone fragments, characterized in that the tibia can be fixed by using a screw in the metal well and screw holes The metal nail may help fix the tibial section that was removed during proximal tibial osteotomy, and to secure the position of the hole into which the screw can be inserted into the tibia to secure the tibia. Stepped tibial upper internal fixation, characterized in that the screw head and the screw hole is in contact with the surface of the round so that the screw and the stepped tibial internal fixation device is in close contact.

최소한의 절개로 큰 고정력을 얻기 때문에 외과 수술 후 환자에게 흉터가 적게 남고, 수술후 뼈의 복원시간에 단축을 주며 따라서 환자의 회복 시간도 빠르다는 장점이 있다. 또한 1차 고정후 고정나사의 위치가 견고하게 결정되기 때문에 의사의 시술에 편리함을 더한다는 특징이 있다. Since a large amount of fixation is obtained with a minimal incision, scars remain in the patient after surgery, and shorten the recovery time of the bone after the surgery, and thus the recovery time of the patient is also fast. In addition, since the position of the fixing screw is firmly determined after the first fixing, it is characterized by the convenience of the doctor's procedure.
