Description

연골 봉합사용 고정플레이트Fixed plate for cartilage suture
본 발명은 연골 봉합사용 고정 플레이트에 관한 것으로, 보다 상세하게 설명하면, 본 발명은 연골 손상 시 연골을 봉합하는 봉합사를 고정플레이트에 직접 봉합할 수 있는 구조를 가지는 연골 봉합사용 고정플레이트에 관한 것이다.The present invention relates to a fixation plate for cartilage suture, and more particularly, the present invention relates to a fixation plate for cartilage suture having a structure capable of directly suturing a suture to the fixation plate when cartilage is damaged.
십자인대는 대퇴골(넙다리뼈)과 경골(정강뼈) 사이를 연결하는 인대로서, 무릎을 안정적으로 위치고정하면서 이동되도록 지지한다.The cruciate ligament is a ligament that connects the femur (thigh bone) and the tibia (shin bone), and supports the knee to be moved while stably fixing it in position.
이러한 십자인대는 경골이 앞으로 밀리는 것을 방지하는 기능을 하기 때문에 단열될 경우 대퇴골에 대해 경골이 앞으로 밀리게 된다.Because these cruciate ligaments function to prevent the tibia from being pushed forward, when insulated, the tibia is pushed forward against the femur.
또한, 십자인대는 경골이 수직축을 중심으로 회전되는 것을 제한하는 역할을 하기 때문에 단열될 경우 경골이 안쪽으로 돌아가게 되어 슬개골탈구를 유발할 수 있다.In addition, since the cruciate ligament plays a role in limiting the rotation of the tibia around the vertical axis, when it is insulated, the tibia may turn inward and cause patellar dislocation.
또한, 십자인대는 무릎의 앞쪽으로 과도하게 회전하는 것을 방지하기 때문에 단열시 대퇴골과 경골의 과도한 꺾임이 발생될 수 있다.In addition, since the cruciate ligament prevents excessive rotation of the knee in the front, excessive bending of the femur and tibia may occur during insulation.
이와같이 십자인대가 단열되었을 경우 슬개관절에 과도한 밀림 또는 당김 또는 회전에 의해 심한 스트레스가 쌓여 관절염을 유발하기 때문에 소형견의 경우에도 수술을 요하게 된다.In this way, when the cruciate ligament is insulated, severe stress is accumulated on the patellar joint by excessive pushing, pulling, or rotation, causing arthritis, so even small dogs require surgery.
상기 십자인대 단열에 의한 수술방식으로는 인공인대를 장착하여 인대를 재건하는 방식이나, 절골수술을 통한 교정방식이 이루어진다. 상기 절골수술로는 대표적으로 TPLO(Tibial plateau leveling osteotomy; 경골 회전절골술) 수술방법을 사용하여 경골 고평부 각도를 사람처럼 5도로 평평하게 하는 시술이 주로 이용되고 있다.As the surgical method by the cruciate ligament insulation, a method of reconstructing the ligament by attaching an artificial ligament or a correction method through osteotomy is performed. As the osteotomy surgery, a procedure of flattening the tibial plateau angle to 5 degrees like a human using a Tibial plateau leveling osteotomy (TPLO) surgical method is mainly used.
또한, 십자인대 손상시에는 슬개골 탈구가 발생되어 슬개골이 수직선상이 아닌 일측으로 편향되어 위치하게 되어 보행시 불편함을 제공한다. 따라서, 상기 TPOL을 시술할 때 슬개골인대가 부착되어 있는 경골의 거친면을 절골하여 위치를 변경시킴으로써 슬개골을 수직라인에 배치되게 하는 TTT(Tibial Tuberosity Transposition;경골조면 변위술)이 같이 시술될 수 있다.In addition, when the cruciate ligament is damaged, patellar dislocation occurs, and the patella is biased to one side rather than on a vertical line, thereby providing discomfort during walking. Therefore, when the TPOL procedure is performed, TTT (Tibial Tubular Transposition), which displaces the rough surface of the tibia to which the patellar ligament is attached, and changes the position to place the patella in a vertical line, can be operated together. .
여기서 상기 TPLO의 경우 뼈판에 의해 절골부위를 고정시키고 있으나, TPLO에서 사용되는 뼈판의 경우 길이방향으로 형성되거나, 접촉면적을 넓혀 넓은 면적을 통해 지지력을 제공하기 위해 머리부를 양측으로 연장된 형태를 제공하기 때문에 측면으로 연장된 뼈판 머리부에 의해 TTT시술시 거친면 절단에 방해를 받게 된다.Here, in the case of the TPLO, the osteotomy part is fixed by the bone plate, but in the case of the bone plate used in the TPLO, it is formed in the longitudinal direction, or the head is extended to both sides to provide support through a wide area by widening the contact area. Because of this, the lateral extension of the head of the bone plate interferes with the cutting of the rough surface during the TTT procedure.
또한, 소형견의 경우 전용 뼈판이 없고 대형견의 뼈판을 단순히 크기만을 축소시켜 제공하기 때문에 다양한 형태의 소형견 경골과는 접합성과 지지력이 다소 떨어지는 문제점이 있다.In addition, in the case of small dogs, there is no dedicated bone plate, and since the bone plate of large dogs is simply provided in a reduced size, there is a problem in that the joint and supporting power are somewhat inferior to the tibia of various types of small dogs.
따라서, 상기와 같은 문제점을 해소하기 위한 방한으로, 국내 등록특허 제10-2210953호 "십자인대 단열수술시 경골에 임플란트되는 동물용 뼈판"이 개시되었다.Therefore, as a way to solve the above problems, Korean Patent Registration No. 10-2210953 entitled "An animal bone plate implanted in the tibia during cruciate ligament ablation surgery" has been disclosed.
상기 발명은 소형견의 경골에 임플란트되는 동물용 뼈판에 관한 것으로, 머리부 후방측 하부 변과 결합공 사이에 제1고정공이 형성되고, 몸체부에는 제4결합공과 제2장공 사이의 전방측 영역에 제2고정공이 형성되어, K-wire가 삽입되어 임시 고정하거나, 슬개골 정렬 수술시 경골 거친면을 지지하기 위한 탄성밴드와이어를 고정시키도록 구성되어, 머리부와 몸체부의 측면에 형성된 다수의 노치에 의해 뼈판 각도를 조절할 수 있어 경골 외면에 뼈판을 최대한 밀착시켜 결합이 이루어지게 할 수 있으며, 특히, 제1고정공과 제2고정공은 케이 와이어(K-wire) 또는 탄성 밴드 와이어(tension band wire)가 삽입 및 연결되어, 결합공의 직경보다 20~30%의 작은 직경으로 형성하여 경골에 연결시 경골파손을 최소화할 수 있도록 하였다.The present invention relates to a bone plate for animals implanted in the tibia of a small dog, wherein a first fixing hole is formed between the lower side of the rear side of the head and the coupling hole, and in the body portion, in the front area between the fourth coupling hole and the second long hole. A second fixing hole is formed to temporarily fix the K-wire by inserting it, or to fix the elastic band wire for supporting the rough surface of the tibia during patella alignment surgery. By adjusting the angle of the bone plate, the bone plate can be brought into close contact with the outer surface of the tibia as much as possible so that the bond can be made. In particular, the first fixation hole and the second fixation hole are K-wire or tension band wire is inserted and connected to form a smaller diameter of 20 to 30% than the diameter of the connecting hole to minimize tibial damage when connected to the tibia.
또, 반월상 연골(Meniscus)은 무릎 관절 내 대퇴골과 경골의 관절면 사이에 위치하는 초승달 모양의 연골로, 무릎관절의 하중과 스트레스를 분산시키고 충격을 흡수하여 관절을 보호한다.In addition, the meniscus is a crescent-shaped cartilage located between the articular surfaces of the femur and tibia in the knee joint, and protects the joint by dispersing the load and stress of the knee joint and absorbing shock.
반월상 연골은 중, 장년층에서 퇴행성 변화에 의한 손상이외에도 젊은 연령층에서 격렬한 움직임이나 외상에 의하여 파열될 수 있는데, 이와 같이 손상된 반월상 연골은 약물 치료, 물리 치료, 주사 치료 등의 비수술적 치료를 사용할 수도 있으나, 자연 회복이 어려워 대부분 수술적 치료가 이루어지고 있다.The meniscus can be ruptured by violent movement or trauma in the younger age group in addition to damage caused by degenerative changes in the middle and old age groups. However, natural recovery is difficult, so most of them are treated surgically.
관절경을 이용한 절제술에서 반월상 연골판은 신경 혈관 손상의 위험 때문에 접근하기가 어렵다. 이에, 반월상연골판 치료를 위해, 봉합술이 최근 가장 각광받고 있다. 예를 들어, 긴 바늘(needle)과 캐뉼러(cannula)를 사용하여 운반되는 봉합사를 이용하는 것이며, 이러한 봉합사 기반 기술은 봉합사에 결합된 앵커(anchor)를 사용하고 있다.In arthroscopic resection, the meniscus is difficult to access due to the risk of neurovascular damage. Thus, for meniscus treatment, suture surgery has recently been in the spotlight. For example, using a suture delivered using a long needle and cannula, this suture-based technique uses an anchor attached to the suture.
대한민국 공개특허 제10-2020-0042776호에는 대표적인 수술적 치료인 반월상 연골 봉합술이 개시되어 있는데, 봉합사가 연결된 앵커(Anchor)를 이용하여 손상된 반월상 연골을 봉합하고 있다. 하지만, 이와 같은 방식은 앵커를 손상된 반원상 연골을 관통하여 고정시킴에 따라 연골 조직의 추가적인 손상을 초래할 수 있고, 또한 봉합사가 연결된 앵커의 고정력이 약하여 수술 후 환자의 움직임에 따라 이탈될 우려가 있었다.Korean Patent Publication No. 10-2020-0042776 discloses a meniscal repair, which is a representative surgical treatment, and sutures the damaged meniscus using an anchor to which a suture is connected. However, this method may cause additional damage to cartilage tissue as the anchor is fixed by penetrating the damaged semicircular cartilage, and the fixing force of the anchor to which the suture is connected is weak, so there is a concern that the anchor may be dislodged according to the patient's movement after surgery. .
따라서, 상기와 같은 문제점을 해소하기 위한 방안으로 국내 특허 등록 제10-2255453호 "반월상 연골 봉합사용 고정 플레이트"가 개발되어 사용되고 있다.Therefore, as a way to solve the above problems, Korean Patent Registration No. 10-2255453 "fixed plate for meniscus suture" has been developed and used.
예를 들면, 상기 반월상 연골 봉합사용 고정 플레이트(100)는 도 1에 도시된 바와 같이, 길이방향을 따라 다수의 수직 나사홀이 관통 형성되어 길이방향으로 연장되어 형성되는 몸체부(110)와, 상기 몸체부(110)를 관통하는 뼈 고정나사(300)에 체결되어 상기 반월상 연골 하부에 형성되는 절개홈(H)에 삽입 고정되는 고정블록(400)과, 상기 몸체부(110)의 상단에 폭 방향으로 연장되어 폭 방향을 따라 다수의 수평 나사홀이 형성되는 헤드부(120); 및 상기 몸체부(110)의 양측에 소정 깊이로 이격되는 한 쌍의 표면홀(201a)과, 상기 몸체부(110)의 양 측면에 인접한 상기 한 쌍의 표면홀(201a)에 연통되는 측면홀(202a)이 몸체부(110)의 길이방향을 따라 연속적으로 형성되어, 상기 반월상 연골을 봉합한 봉합사(200)가 상기 표면홀(201a)과 측면홀(202a)을 관통하여 몸체부(110)에 결속되도록 한 구성이다.For example, as shown in FIG. 1, the fixing plate 100 for meniscus suturing includes a body portion 110 formed by extending a plurality of vertical screw holes along the longitudinal direction to extend in the longitudinal direction, as shown in FIG. , The fixing block 400 fastened to the bone fixing screw 300 penetrating the body portion 110 and inserted into the incision groove H formed below the meniscus, and the body portion 110 A head portion 120 extending in the width direction at an upper end and having a plurality of horizontal screw holes formed along the width direction; and a pair of surface holes 201a spaced apart by a predetermined depth on both sides of the body 110 and side holes communicating with the pair of surface holes 201a adjacent to both sides of the body 110. (202a) is continuously formed along the longitudinal direction of the body portion (110), so that the suture (200) sutured the meniscus passes through the surface hole (201a) and the side hole (202a) to form the body portion (110). ) is a configuration that is bound to.
상기와 같이 구성되는 고정 플레이트는 도 2에 도시된 바와 같이, 봉합사(200)를 일측의 표면홀(201a)과 측면홀(202a)을 관통하여 결속하거나(2a), 한 쌍의 표면홀(201a)과 측면홀(202a)을 폭 방향으로 횡단하여 결속하거나(2b), 한 쌍의 표면홀(201a)과 측면홀(202a)을 길이방향으로 서로 연결하여 결속하여 시술하였다(2c).As shown in FIG. 2, the fixing plate configured as described above binds the suture 200 through one side surface hole 201a and side hole 202a (2a), or a pair of surface holes 201a. ) and side holes 202a in the width direction (2b), or a pair of surface holes 201a and side holes 202a were connected to each other in the longitudinal direction and bound together (2c).
그런데, 시술시 봉합사를 연골과 고정 플레이트와 직접 결속하는 것이 아니고, 봉합사를 표면홀(201a)과 측면홀(202a)을 통하여 연골(C)을 결속하는 구조로 되어 있다.However, during the procedure, the suture thread is not directly bound to the cartilage and the fixed plate, but the suture thread binds the cartilage C through the surface hole 201a and the side hole 202a.
이러한 시술은 고정플레이트와 연골의 결속력이 취약한 문제점이 있다.This procedure has a problem in that the binding force between the fixation plate and the cartilage is weak.
예를들면, 통상적으로 근위 상완골 골절 치유 시 Supraspinatus(극상근), subscapularis(견갑하근)의 강한 힘에 의한 수술 이후의 재 파열(골절)을 주의해야 한다. 이러한 재 파열을 막기 위해 통상적으로 사용하는 치유법은 해당 근육과 뼈, 임플란트를 Suturing(봉합)하는 방법이다.For example, when healing proximal humerus fractures, attention should be paid to re-rupture (fracture) after surgery due to the strong power of the supraspinatus (supraspinatus) and subscapularis (subscapularis). A commonly used healing method to prevent re-rupture is to suture the muscles, bones, and implants.
그런데, 상기 고정플레이트를 사용하는 시술의 경우는 근육과 뼈를 동시에 봉합하지 못하는 문제점이 있다.However, in the case of the procedure using the fixing plate, there is a problem in that muscles and bones cannot be sutured at the same time.
특히, 상기와 같은 고정플레이트를 이용한 봉합(Suturing)법은 시술자의 능력에 따라 효과가 차이가 나는데, 골 정복(Bone reduction) 이후 봉합술(Suturing) 하는 것이 가장 정확하고 안전하게 수술이 가능한 방법이나 이러한 시술방법은 환자의 회복시간을 더디게 하는 문제점이 있었다.In particular, the suturing method using a fixed plate as described above has a different effect depending on the operator's ability, and suturing after bone reduction is the most accurate and safe method for surgery, but such a procedure The method had a problem of slowing the patient's recovery time.
또한, 연골의 결속을 위해 몸체부(110)와 같은 연장플레이트가 형성되어 있으나 시술이 번거롭고 이에 따른 제작비 상승 등의 문제점이 있었다.In addition, although an extension plate like the body portion 110 is formed to bind the cartilage, the procedure is cumbersome and there are problems such as an increase in production cost.
따라서, 본 발명은 상술한 바와 같은 종래의 제반 문제점들을 해소하기 위하여 창안된 것으로서, 고정플레이트를 연골과 직접적으로 봉합할 수 있는 구조를 갖는 연골 봉합사용 고정 플레이트를 제공함에 있다.Accordingly, the present invention has been devised to solve all the problems of the prior art as described above, and is to provide a fixation plate for cartilage suture having a structure capable of directly suturing the fixation plate to cartilage.
다른 목적은 종래 고정플레이트에 사용되는 몸체부(연장플레이트)가 불필요하여 제작 및 생산단가를 현저하게 저감시킬 수 있도록 하는 데에 있다.Another object is to make it possible to significantly reduce manufacturing and production costs because the body part (extension plate) used in the conventional fixing plate is unnecessary.
또 다른 목적은 골절된 뼈에 플레이트를 식립한 후에 근육과 함께 봉합술( Suturing)을 할 수 있도록 하는 데에 있다.Another purpose is to enable suturing with muscles after placing a plate on a fractured bone.
상기와 같은 기술적 과제를 달성하기 위한 본 발명은 근위 상완골 골절 치유 시 극상근, 견갑하근의 강한 힘에 의한 수술 이후의 재 파열(골절)을 막기 위해 해당 근육과 뼈, 고정임플란트를 동시에 봉합할 수 있도록 한 고정플레이트를 제공하되, 상기 연골 봉합사용 고정플레이트(100)는 바닥면에 근육과 뼈를 함께 봉합할 수 있도록 일측에 개구된 개구홈(111)이 형성되며, 상기 개구홈(111)에 적어도 하나 이상의 봉합홀(112)이 관통 형성된 것을 특징으로 한다.The present invention for achieving the above technical problem is to prevent re-rupture (fracture) after surgery due to the strong force of the supraspinatus and subscapularis muscles when healing proximal humerus fractures, so that the corresponding muscles, bones, and fixed implants can be sutured at the same time A fixing plate is provided, but the fixing plate 100 for cartilage suture has an opening groove 111 formed on one side so as to suture muscles and bones together on the bottom surface, and at least in the opening groove 111 It is characterized in that one or more sealing holes 112 are formed through.
상기 개구홈(111)은 길이방향으로 길게 형성되며 일측이 개구되고, 타측은 봉합바늘이 잘 통과할 수 있도록 경사면(111a)이 형성된다.The opening groove 111 is formed long in the longitudinal direction, one side is open, and the other side is formed with an inclined surface 111a so that the suture needle can pass through.
또한, 골절 뼈조각이 작을 경우 눌러줄 수 있도록 봉합홀(112)이 고정플레이트(100)의 외곽을 따라 다수 형성하거나 골편이 클 경우 단단히 눌러줄 수 있도록 상기 고정플레이트(100) 상단부에 롱 스크류 삽입홀(101)이 형성된다.In addition, a number of suture holes 112 are formed along the outer edge of the fixing plate 100 to press when the bone fragment is small, or a long screw is inserted into the upper end of the fixing plate 100 so that it can be firmly pressed when the bone fragment is large. A hole 101 is formed.
또한, 상기 고정플레이트(100)의 하단부에 자유로운 포지셔닝을 위한 장공(102)이 형성되어 뼈조각의 크기에 따라 스크류 삽입위치를 조절할 수 있도록 구성된다.In addition, a long hole 102 for free positioning is formed at the lower end of the fixing plate 100 so that the screw insertion position can be adjusted according to the size of the bone fragment.

둘째, 고정플레이트와 연골을 직접적으로 봉합할 수 있도록 상기 고정플레이트 측면에 바늘유도구가 형성되어 고정플레이트를 연골과 밀착되게 고정할 수 있도록 함으로써, 기존 나사체결에만 의존한 시술에 비해 시술 후 후유증을 현저하게 감소시킬 수 있음과 아울러 회복기간을 단축시킬 수 있도록 하였다.Second, a needle guide tool is formed on the side of the fixation plate so that the fixation plate and the cartilage can be directly sutured so that the fixation plate can be fixed closely to the cartilage, thereby reducing post-operative sequelae compared to conventional procedures relying only on screw fastening. It can be significantly reduced and the recovery period can be shortened.
셋째, 고정플레이트 상단부근에 긴장력(Tendon force)에 저항하기 위한 나사홀을 형성하고, 하단부에 자유로운 포지셔닝을 위한 장공을 추가함으로써, 고정플레이트의 시술을 유연하게 할 수 있도록 하였다.Third, by forming a screw hole to resist Tendon force near the upper end of the fixing plate and adding a long hole for free positioning at the lower end, it was possible to flexibly operate the fixing plate.
넷째, 골절된 뼈에 플레이트를 식립한 후에 근육과 함께 봉합(Suturing)을 할 수 있도록 함으로써, 시술시간 단축과 환자의 회복시간을 단축시키는 효과가 있다.Fourth, after placing the plate on the fractured bone, it is possible to perform suturing together with the muscle, thereby reducing the procedure time and the patient's recovery time.
