Abstract
Description
본 발명은 척추 고정 시스템의 로드 연결장치에 관한 것이다.The present invention relates to a rod connection of a spinal fixation system.
일반적으로 척추가 골절되거나 질병이 발생하면 척추를 고정시켜 주게 되는데, 척추를 고정시키는 척추 고정 시스템은 도1에 도시한 바와 같이, 척추에 일정한 간격으로 고정 결합되는 척추경 나사부재(2)와, 상기 척추경 나사부재(2)에 결합되어 척추를 지지하는 한쌍의 로드(4)와, 상기 한쌍의 로드(2)를 서로 연결하는 로드 연결장치(10)를 포함하여 구성된다. 상기 로드 연결장치(10)는 양측 로드(2)사이 간격을 일정하게 유지하여 지지하는 역활을 한다.In general, when the spine is broken or a disease occurs is to fix the spine, the spinal fixation system for fixing the spine, as shown in Figure 1, the pedicle screw member (2) is fixedly coupled to the spine at regular intervals, It is configured to include a pair of rods (4) coupled to the pedicle screw member (2) to support the spine, and a rod connecting device (10) connecting the pair of rods (2) to each other. The rod connecting device 10 serves to support and maintain a constant gap between the rods 2 on both sides.
종래 로드 연결장치(10)는, 상기 로드(4)에 걸리는 갈고리 형태의 훅(12)과, 상기 훅(12)을 연결하도록 상기 훅(12)을 관통하여 설치된 연결부재(14)와, 상기 훅(12)에 나사결합되어 상기 연결부재(14)를 상기 로드(4)에 압착하여 고정하는 세트 스크류(16)로 이루어 진다. 상기 세트 스크류(16)를 조이면, 상기 연결부재(14)가 상기 로드(4)의 상측을 누르는 한편 상기 훅(12)의 갈고리부가 로드(4)의 하측에 밀착하여 양 로드(4)가 움직이지 않게 지지된다.Conventional rod connecting device 10, a hook-shaped hook 12 that is caught on the rod 4, a connecting member 14 provided through the hook 12 to connect the hook 12, and the Is screwed to the hook 12 is made of a set screw 16 for pressing and fixing the connecting member 14 to the rod (4). When the set screw 16 is tightened, the connecting member 14 presses the upper side of the rod 4 while the hook portion of the hook 12 is in close contact with the lower side of the rod 4 so that both rods 4 move. It is not supported.
그런데, 이와 같이 구성된 종래의 로드 연결장치는, 연결부재(14)를 훅(12)의 측부에서 끼워야 하므로 시술하기가 용이하지 않다는 문제점이 있었다.By the way, the conventional rod connection device configured as described above has a problem in that it is not easy to perform the procedure because the connection member 14 must be fitted at the side of the hook 12.
또한, 세트 스크류(16)의 조임에 따라 로드(4)에 대해 연결부재(14) 및 훅(12)이 수직방향으로 작용하는 힘만을 받아 로드(4)에 밀착되므로 체결력이 약하여, 척추의 움직임에 따라 로드(4)가 틀어지는 등 횡방향으로 힘을 받게 되면 세트스크류(16)가 풀리고 연결부재(14)가 움직이게 되며, 이로 인해 척추 내에 시술된 척추고정장치의 로드 연결장치에 의해 사용자가 통증을 겪게 되는 등의 문제점이 있었다.In addition, since the connecting member 14 and the hook 12 with respect to the rod 4 in accordance with the tightening of the set screw 16 receives only a force acting in the vertical direction close to the rod 4, the fastening force is weak, the movement of the spine When the rod 4 is twisted, the set screw 16 is loosened and the connecting member 14 is moved when the rod 4 is twisted. As a result, the user suffers a pain due to the rod connecting device of the spinal fixing device which is operated in the spine. There was a problem such as experiencing.
따라서, 본 발명은 상기 문제점을 해결하기 위해 이루어진 것으로서, 본 발명의 목적은, 시술시 로드를 간단히 연결할 수 있고 로드에 대한 체결력을 높이는 척추 고정 시스템의 로드 연결장치를 제공하는데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a rod connecting device of the spinal fixation system that can easily connect the rod during the procedure and increase the fastening force to the rod.

And the second hooks 28 and 30 are connected to each other by a connecting member 32, and the hooks 28 and 30 and the connecting member 32 are connected to the rods by fixing members 34 and 36 made of nuts. 24, 24 '). In addition, first and second washers 38 and 40 are coupled to both ends of the connecting member 32 to be fitted to the first and second hooks 28 and 30. The first and second washers 38 and 40 do not need to be coupled.
상기 제1 및 제2훅(28, 30)은, 상기 고정부재(34, 36)가 나사결합되는 나사봉부(42, 42')와, 상기 로드(24, 24')의 상측에서 끼워져 로드를 잡는 로드 수용부(44a, 44'a)가 형성된 홀딩부(44, 44')로 이루어 진다.The first and second hooks 28 and 30 are fitted with screw rods 42 and 42 'to which the fixing members 34 and 36 are screwed, and the rods 24 and 24'. The holding portions 44 and 44 'are formed with rod receiving portions 44a and 44'a for holding the rods.
상기 로드 수용부(44a, 44'a)의 중앙에는 훅의 길이방향 상측으로 슬릿홈(44b, 44'b)이 형성되어 상기 로드(24, 24')를 양측에서 가압하는 플랜지(44c, 44'c)를 이룬다. 상기 슬릿홈(44b, 44'b)는 상기 나사봉부(42, 42')의 중간까지 연장형성된다.Slit grooves 44b and 44'b are formed in the center of the rod receiving portions 44a and 44'a in the longitudinal direction of the hooks to press the rods 24 and 24 'from both sides. 'c). The slit grooves 44b and 44'b extend to the middle of the screw rods 42 and 42 '.
그리고, 상기 연결부재(32)의 양단 배면 또는 상기 와셔(38, 40)의 배면이 밀착하여 상기 플랜지(44c, 44'c)에 상기 로드(24, 24')를 향해 수직 및 수평방향의 힘을 가하도록 상기 홀딩부(44, 44')의 외주면은 하측으로 갈수록 외경이 커지는 경사면으로 되어 있다.In addition, the rear surfaces of both ends of the connecting member 32 or the rear surfaces of the washers 38 and 40 are in close contact with each other so that the flanges 44c and 44'c face the rods 24 and 24 'in the vertical and horizontal directions. The outer circumferential surfaces of the holding portions 44, 44 'are inclined surfaces whose outer diameter increases toward the lower side so as to be applied.
도4 및 도5에 도시한 바와 같이, 상기 연결부재(32)는 플레이트로 된 로드로서, 그 양단부는 중간부보다 두껍고, 그 양단부에는 상기 훅의 나사봉부(42, 42')가 끼워지도록 구멍(32a, 32a')이 형성되고, 그 양단부의 배면에는 상기 와셔(38, 40)를 수용하는 수용홈(32b, 32b')이 형성된 구조이다. 상기 구멍(32a)은 상기 로드(24, 24')사이의 간격에 따라 상기 훅과 상대적으로 슬라이딩하여 고정되도록 연결부재(32)의 길이방향으로 형성된 장공이다.As shown in Figs. 4 and 5, the connecting member 32 is a rod made of a plate, and both ends thereof are thicker than the middle part, and both ends thereof are fitted with threaded rods 42 and 42 'of the hook. The holes 32a and 32a 'are formed, and the rear surfaces of the ends 32 are formed with receiving grooves 32b and 32b' for accommodating the washers 38 and 40. The hole 32a is a long hole formed in the longitudinal direction of the connecting member 32 to be fixed by sliding relative to the hook in accordance with the interval between the rods (24, 24 ').
상기 와셔(38, 40)의 구멍 하단부에는 상기 훅의 홀딩부(44, 44')의 경사면에 접촉하는 면적을 높이도록 경사면(38a, 40a)이 형성된다. 그리고, 상기 장공으로 된 구멍(32a)에 맞추어 장공으로 된 수용홈(32b)의 측벽에 용이하게 접촉하도록 상기 와셔(38)의 외주면에는 평탄면(38b)이 형성된다.Inclined surfaces 38a and 40a are formed at lower ends of the holes of the washers 38 and 40 so as to increase the area in contact with the inclined surfaces of the holding portions 44 and 44 'of the hooks. A flat surface 38b is formed on the outer circumferential surface of the washer 38 so as to easily contact the sidewall of the receiving hole 32b formed in the long hole in accordance with the long hole 32a.
이와 같이 구성된 본 발명에 의한 척추 고정 시스템의 로드 연결장치에서, 척추에 척추경 나사부재(22, 22') 및 로드(24, 24')를 설치한 후, 훅(28, 30)의 로드 수용부(44a, 44'a)가 상기 로드(24, 24')를 상측에서 감싸도록 훅(28, 30)을 로드(24, 24')의 상측에서 눌러 끼운 다음, 와셔(38, 40)가 결합된 연결부재(32)를 상기 훅의 나사봉부(42, 42')에 끼우고, 고정부재(34, 36)로 조우면 로드 연결장치의 설치가 간단히 완료된다. 이때, 상기 고정부재(34, 36)는 와셔를 매개로 연결부재(32)에 고정할 수도 있다.In the rod connecting device of the spinal fixation system according to the present invention configured as described above, after the pedicle screw members 22 and 22 'and the rods 24 and 24' are installed in the spine, the rods 28 and 30 are accommodated in the rods. The hooks 28, 30 are pressed against the top of the rods 24, 24 'such that the portions 44a, 44'a wrap the rods 24, 24' from above, and then the washers 38, 40 The combined connecting member 32 is inserted into the screw rods 42 and 42 'of the hook, and the fixing member 34 and 36 are tightened to complete the installation of the rod connecting device. At this time, the fixing members 34 and 36 may be fixed to the connecting member 32 via a washer.
이와 같이 구성된 로드 연결장치는 도6(일측의 훅만 표시)에 도시한 바와 같이, 상기 고정부재(34, 36)를 조울 때 와셔(38, 40) 및 연결부재(32)가 훅의 홀딩부(44, 44')의 경사면을 상측에서 가압하게 되어 플랜지(44c, 44'c)를 누르게 되는데, 상기 플랜지(44c, 44c')는 로드(24)에 대해 수직력(V)와 수평력(H)을 가하므로, 견고하게 체결되어 풀릴 염려가 없다.In the rod connecting device configured as described above, as shown in FIG. 6 (only the hook on one side), the washers 38 and 40 and the connecting member 32 are held by the hook when the fixing members 34 and 36 are tightened. 44, 44 ') is pressed from the upper side to press the flange (44c, 44'c), the flange (44c, 44c') is a vertical force (V) and horizontal force (H) with respect to the rod (24) Therefore, there is no fear of being firmly tightened and loosened.
본 발명에 의한 척추 고정 시스템의 로드 연결장치에 의하면, 시술시 로드를 간단히 연결할 수 있다. 그리고, 훅 및 연결부재의 체결력을 높여 연결의 신뢰성을 높일 수 있으므로, 척추내에 시술된 후 로드 연결장치가 풀리는 등으로 인한 트러블을 줄일 수 있다.According to the rod connecting device of the spinal fixation system according to the present invention, it is possible to simply connect the rod during the procedure. In addition, since the reliability of the connection can be increased by increasing the fastening force of the hook and the connection member, trouble caused by loosening of the rod connecting device after being performed in the spine can be reduced.
