Description

무지외반증 교정수술 장치{Appatatus for hallux valgus correction}Valgus correction surgery device {Appatatus for hallux valgus correction}

본 발명은 무지외반증 교정수술에 사용되는 수술장치에 관한 것이다.The present invention relates to a surgical device used in valgus corrective surgery.

무지외반증(Hallux Valgus)은 엄지 발가락의 뿌리 부분인 제1중족지 관절에서 무지가 외측으로, 제1중족골이 내측으로 변형되는 질환으로 엄지발가락의 돌출된 부분이 신발과 마찰을 일으키면서 통증을 유발한다. 무지외반증은 선천적인 원인도 있지만, 대부분 뾰족한 신발을 신어서 엄지 발가락이 측면으로 밀리게 되어 발생한다.Hallux Valgus is a disease in which the thumb is deformed outward at the first metatarsal joint, which is the root of the big toe, and the first metatarsal bone is deformed inward.The protruding part of the big toe causes friction with the shoe, causing pain. do. Algebraic valgus has a congenital cause, but most of them are caused by wearing pointed shoes and pushing the big toe to the side.

이와 같이 대부분 후천적으로 발생하는 무지외반증을 교정하기 위하여 대한민국 실용신안공개 제2011-0011414호(무지외반증용 교정기), 실용신안등록 제20-0457048호(무지외반증 교정용 신발), 특허등록 제10-1509404호(무지외반증 교정용 신발창)이 제안되었다.In order to correct valgus valgus that occurs most of the above, Korean Utility Model Publication No. 2011-0011414 (corrector for valgus valgus), Utility model registration No. 20-0457048 (shoes for valgus valgus correction), patent registration No. 10- 1509404 (Shoe sole for valgus correction) was proposed.

이와 같이 개시된 기술들은 대부분 후천적으로 발생하는 무지외반증을 교정하기 위한 기구로서, 선천적인 원인이거나 엄지발가락의 휨 정도가 큰 심한 무지외반증의 교정에는 효과가 크지 않다. 선천적이거나 정도가 심한 무지외반증의 교정을 위하여 절골술이 이루어지고 있는데, 무지외반증 절골술은 휘어진 중족골의 측면을 일부 절개하여 정상적인 각도로 조정한 후, 도 5에 도시된 바와 같이 금속나사를 삽입하여 고정하여 이루어진다.The techniques disclosed as described above are instruments for correcting valgus valgus that occur mostly acquired, and are not very effective in correcting severe valgus valgus that is congenital or has a large degree of bending of the big toe. Osteotomy is being performed to correct congenital or severe valgus valgus. In valgus valgus osteotomy, the side of the curved metatarsal bone is partially incised and adjusted to a normal angle, and then a metal screw is inserted and fixed as shown in FIG. Done.

그리고, 무지외반증 절골술용 금속나사는 고정력이 약하여 중족골의 유동에 의해 나사가 중족골로부터 이탈되는 풀아웃 현상이 종종 발생하고, 또한 다수 나사가 사용됨에 따라 수술이 번거로우며, 각각의 나사가 교정각에 따라 정확하게 배향되어 삽입되어야 하는 어려움이 있다. And, the metal screw for valgus osteotomy is weak in fixing power, so a pull-out phenomenon in which the screw is separated from the metatarsal bone due to the flow of the metatarsal bone often occurs.In addition, as a number of screws are used, the operation is cumbersome, and each screw is applied to the corrective angle. It is difficult to be correctly oriented and inserted accordingly.

도 1은 본 발명의 일 실시예에 따른 무지외반증 교정수술 장치(100)의 사시도이고, 도 2는 이의 단면도이고, 도 3은 본 발명의 무지외반증 교정수술 장치(100)를 중족골(30)의 절개홈(30a)에 고정하는 동작을 도시한 도면이며, 도 4는 무지외반증 교정수술 장치(100)가 중족골(30)의 절개홈(30a)에 고정된 상태를 도시한 도면이다.FIG. 1 is a perspective view of a valgus valgus corrective surgery apparatus 100 according to an embodiment of the present invention, FIG. 2 is a cross-sectional view thereof, and FIG. 3 is a view showing the metatarsal bone 30 of the valgus valgus corrective surgery apparatus 100 of the present invention. It is a view showing the operation of fixing the incision groove (30a), Figure 4 is a view showing a state in which the valgus corrective surgery apparatus 100 is fixed to the incision groove (30a) of the metatarsal (30).

도 1 내지 4를 참조하면, 본 발명에 따른 교정수술 장치(100)는 소정 두께의 판형태로 이루어진 중족골 고정판(10)과, 중족골 고정판(10)으로부터 수직방향으로 돌출된 돌출 삽입부(20)를 구비한다. 1 to 4, the orthodontic surgery apparatus 100 according to the present invention includes a metatarsal fixing plate 10 made of a plate shape having a predetermined thickness, and a protruding insertion part 20 protruding in a vertical direction from the metatarsal fixing plate 10. It is equipped with.

중족골 고정판(10)은 절개된 중족골(30)의 표면에 접하도록 일정 폭을 가지고 소정면을 구비한 금속판으로, 중족골(30)의 표면에 접하는 하면(11)과 외부로 노출되는 상면(12)을 구비한다. 중족골 고정판(10)에는 중족골(30) 표면에 고정되는 고정나사(40)가 삽입되는 고정나사홀(13)이 형성되는데, 고정나사홀(13)은 고정나사(40)를 수용하도록 상부면이 아래방향으로 경사면을 이루는 것이 바람직하다. The metatarsal fixing plate 10 is a metal plate having a predetermined width and having a predetermined surface to contact the surface of the incision metatarsal bone 30, and has a lower surface 11 in contact with the surface of the metatarsal bone 30 and an upper surface 12 exposed to the outside. Equipped. The metatarsal fixing plate 10 has a fixing screw hole 13 into which a fixing screw 40 fixed to the surface of the metatarsal bone 30 is inserted, and the fixing screw hole 13 has an upper surface to accommodate the fixing screw 40. It is desirable to form an inclined surface downward.

고정판(10)의 하면(11)에는 하나 이상의 스파이크(14)가 돌출 형성되는데, 스파이크(14)는 도면에 도시된 바와 같이 끝단이 날카로운 역삼각형 형상으로 하면(11)으로부터 균일한 높이로 돌출되어 중족골 고정판(10)의 길이방향으로 다수개 형성되는 것이 바람직하다.One or more spikes 14 are protruding from the lower surface 11 of the fixing plate 10, and the spikes 14 protrude from the lower surface 11 to a uniform height in a sharp inverted triangle shape as shown in the figure. It is preferable that a plurality of metatarsals are formed in the longitudinal direction of the fixing plate 10.

돌출 삽입부(20)는 하면(11)으로부터 수직 방향으로 돌출되어 중족골(30)의 절개홈(30a)에 삽입되어 중족골(30)을 지지하는 몸체로서, 고정판(10)의 하면(11)으로부터 소정 길이로 돌출 연장되는 한 쌍의 내측지지면(21,22)과, 한 쌍의 내측지지면(21,22)을 연결하는 측면(23)을 구비한다. 한 쌍의 내측지지면(21,22)은 돌축 삽입부(20)의 상부면과 하부면을 이루는데, 경사지게 절개된 중족골(30)의 절개홈(30a)의 내측면에 접하도록 경사면으로 형성된다. 한 쌍의 내측지지면(21,22)에는 고정 톱니(24)가 형성되는 것이 바람직한데, 고정 톱니(24)는 도면에 도시된 바와 같이 중족골 고정판(10)을 향해 경사지게 형성하는 것이 바람직한데, 이로써 돌출 삽입부(20)가 중족골(30)의 절개홈(30a)으로 진입은 용이하지만 절개홈(30a)의 외측으로는 후퇴하지 않게 된다.The protruding insertion part 20 is a body that protrudes from the lower surface 11 in a vertical direction and is inserted into the incision groove 30a of the metatarsal bone 30 to support the metatarsal bone 30, from the lower surface 11 of the fixing plate 10 A pair of inner support surfaces 21 and 22 protruding to a predetermined length and side surfaces 23 connecting the pair of inner support surfaces 21 and 22 are provided. The pair of inner support surfaces 21 and 22 form the upper and lower surfaces of the stone shaft insertion part 20, and are formed as an inclined surface so as to contact the inner surface of the incision groove 30a of the metatarsal bone 30 that has been incised obliquely. do. It is preferable that the fixed teeth 24 are formed on the pair of inner support surfaces 21 and 22, and the fixed teeth 24 are preferably formed to be inclined toward the metatarsal fixing plate 10 as shown in the drawing, Thereby, the protruding insertion portion 20 can easily enter the incision groove 30a of the metatarsal bone 30, but does not retreat to the outside of the incision groove 30a.

교정수술 장치(100)의 재질로는 생체안정성이 있는 스테인레스 스틸 또는 티타늄 합금이 사용될 수 있는데, 체액과의 화학반응을 차단하기 위해 표면에 티타늄 코팅층을 형성하는 것이 바람직한데, 티타늄 코팅층은 티타늄 이온을 진공상태에서 교정수술 장치(100) 표면에 기상 증착시킴으로써 형성된다.As the material of the orthodontic surgery device 100, stainless steel or titanium alloy having biostable stability may be used, and it is preferable to form a titanium coating layer on the surface to block chemical reactions with body fluids. It is formed by vapor deposition on the surface of the orthodontic surgery apparatus 100 in a vacuum state.

이와 같은 본 발명의 무지외반증 교정수술 장치(100)는 중족골 절개홈(30a)의 내측면과 이격없이 이격없이 밀착 고정할 수 있어 절개홈(30a)의 외측으로 이탈되지 않으며, 중족골(30)의 길이방향으로 외력이 작용하더라도 중족골(30)의 표면 전체에 균일하게 분산될 수 있어 절개홈의 내측면에서 골 결손이 발생하지 않게 된다.As such, the valgus valgus corrective surgery apparatus 100 of the present invention can be fixed in close contact with the inner side of the metatarsal incision groove 30a without spaced apart, so that it does not deviate to the outside of the incision groove 30a, and the metatarsal bone 30 Even if an external force acts in the longitudinal direction, it can be uniformly distributed over the entire surface of the metatarsal bone 30, so that bone defects do not occur on the inner surface of the incision groove.

이상과 같이 설명한 본 발명은 기재된 실시예에 한정되는 것은 아니고, 본 발명의 사상 및 범위를 벗어나지 않고 다양하게 수정 및 변형할 수 있음은 이 기술의 분야에서 통상의 지식을 가진 자에게 자명하다. 따라서 그러한 변형예 또는 수정예들은 본 발명의 특허청구범위에 속한다 해야 할 것이다.The present invention described above is not limited to the described embodiments, and it is apparent to those of ordinary skill in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention.
