Description

Technical Field

[0001] The present invention belongs to the technical field of medical device equipment, and specifically relates to a spinal coplanar orthopedic connection component and a using method thereof. Background Art

[0002] The normal spine is composed of many vertebral bodies with a certain degree of mobility. The three-dimensional coordinate axes corresponding to each vertebral body can be respectively corresponding to the basic sections of the human body. That is, the axis perpendicular to the coronal plane corresponds to the X-axis, the axis perpendicular to the sagittal plane is the Y-axis, and the axis perpendicular to the transverse plane is the Z-axis. And the so-called coplanar means that when a normal person is in an upright or lying flat state, the spinal vertebral bodies are in the same plane on the X-axis and the Z-axis, and there is no movement and rotation in the coronal plane and the horizontal plane.

[0003] However, when the spine is displaced due to some diseases or accidents, it will bring great troubles to the life of the patient. Specifically, scoliosis caused by genetic defects and spinal injuries. If such conditions are not treated in time, it will further lead to the occurrence of some other diseases such as intervertebral discs. For this reason, some orthopedic tools are needed to correct the spine and restore it to a relatively normal state.

[0004] At present, the coplanar orthopedic system with the action of double rods can achieve good clinical results when orthopedic treating non-planar vertebral bodies. However, due to the irregularity and randomness of the displacement of the vertebral bodies with scoliosis, the traditional double-rod coplanar orthopedic system will bring certain troubles to doctors during the rod-passing operation in the surgery. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a spinal coplanar orthopedic connection component, which mainly has the advantages of facilitating the operation of doctors during the surgery for patients with scoliosis, shortening the operation time, having a simple structure and being easy to use, and solves the problems mentioned in the above background art.

[0006] The present invention provides the following technical solution: A spinal coplanar orthopedic connection component, including at least one sleeve. The lower part of the sleeve is connected to the anchor point on the vertebral body. An enhancement ring is sleeved outside the upper part of the sleeve. The enhancement ring includes a fixing hole and a rod body channel. The fixing hole cooperates with the upper part of the sleeve, and the rod body channel is used for accommodating the second rod. The axes of the fixing hole and the rod body channel on each enhancement ring are in a skew relationship in space. The first rod passes through the middle of the upper part of the sleeve.

[0007] In the prior art, in the case of scoliosis, the operation of threading the rod during surgery using a traditional double-rod coplanar orthopedic system will cause certain troubles to doctors, and the difficulty of threading the rod is high. However, in the improved technical solution of the present invention, the strengthening ring connects the first rod and the second rod. Through the cooperation of the strengthening ring, the sleeve and the second rod, the threading of the first rod is completed, so that the connection part between the lower end of the sleeve and the vertebral body also forms a straight line. In a coplanar manner, the vertebral body is pulled back to the normal position, and a non-coplanar angle is formed between the axes, so that the first rod and the second rod are cross-fixed in multiple axes in three-dimensional space.

[0008] The sleeve includes a cylinder body. There is a sleeve upper groove on the upper part of the sleeve and a sleeve lower groove on the lower part of the sleeve. The fixing hole and the rod body channel are respectively located at both ends of the strengthening ring. The fixing hole and the rod body channel are both through structures along their respective axes. The second rod sequentially passes through the rod body channel on the right side of the strengthening ring. Through the second rod, the strengthening rings are connected in series and are on the same straight line. Then the first rod is passed through the sleeve upper groove on the upper part of the sleeve, and the first rod is pressed down so that the connection part between the lower part of the sleeve and the vertebral body also forms a straight line. There are sleeve upper grooves on both sides of the upper part of the sleeve, and sleeve lower grooves are provided on both sides of the lower part of the sleeve.

[0009] The inner wall of the fixing hole is provided with a guiding block, which cooperates with the sleeve upper groove. The rod body channel includes a first side, and the first side is arc-shaped. The radius of curvature of the first side matches the diameter of the second rod, and the remaining edges are free contours without constraints.

[0010] The cooperation between the guiding block and the sleeve upper groove can provide a clear movement trajectory for the strengthening ring, ensure movement along a predetermined path, and avoid deviation or dislocation; it is convenient for quick insertion and extraction and simplifies the installation process; the contact surface between the guiding block and the sleeve upper groove provides multi-point support, reduces vibration or shaking during movement, and enhances the structural stability. The cross-sectional area shape of the rod body channel is designed separately. For the first side of the rod body channel, the first side is the cross-sectional contour line of the inner wall on the side of the rod body channel close to the fixing hole. The first side is arc-shaped, and the radius of curvature of the first side matches the diameter of the second rod. Finally, the second rod is limited to the side of the rod body channel close to the fixing hole. Therefore, for the stability of the limitation of the second rod, the remaining edges are free contours without constraints, which can realize subsequent contour designs of various rod body channels and make the strengthening ring suitable for more occasions.

[0011] A damping nail threaded hole is provided on the hole wall of the fixing hole. The damping nail threaded hole communicates with the fixing hole and is used to cooperate with a damping screw to prevent the strengthening ring from slipping off the sleeve. The anchor point is a fixing nail driven into the vertebral body.

[0012] The rod body channel is a closed channel, and the cross-sectional area is closed.

[0013] The reinforcing ring includes reinforcing ring A, and the cross-sectional area of the reinforcing ring A is a closed-hole structure, with dimensions matching those of the second rod.

[0014] The reinforcing ring is an adjustable reinforcing ring. The cross-sectional area of the rod channel of the adjustable reinforcing ring is closed. The left inner wall of the rod channel is an arc-shaped first side, and the shape formed by the remaining edges can increase the movement range of the second rod. The rod channel is provided with a push block and a push rod screw. The push block is inside the rod channel, and the push rod screw is in mutual cooperation with the push rod threaded hole opened on the wall of the rod channel. By rotating the push rod screw, the push block can move back and forth in the rod channel.

[0015] Compared with the reinforcing ring A, the shape formed by the remaining edges of the right rod channel of the adjustable reinforcing ring can increase the movement range of the second rod, making the rod channel of the adjustable reinforcing ring larger and more convenient for the second rod to penetrate. At the same time, the push block and the push rod screw can push the second rod to move in the rod channel, making the adjustable reinforcing ring in a straight line.

[0016] The reinforcing ring includes reinforcing ring D. The reinforcing ring D is a split and detachable structure, including left ring D and right ring D. Left ring D is the end where the fixing hole is located in the reinforcing ring D, and right ring D is the end where the rod channel is located in the reinforcing ring D. The right ring D and the left ring D are assembled together so that the right ring D can rotate around the left ring D to a certain extent.

[0017] When the vertebral body rotates a certain angle along the Y-axis, the rod-passing hole of the traditional reinforcing ring will form a certain angle with the second rod. When the angle is too large, it may even lead to the failure of rod passing. This structure compensates for the generated angle by rotating the right ring D, thereby solving the problem of rod passing in the case of vertebral body rotation along the Y-axis.

[0018] One of the connecting ends of the left ring D and the right ring D is provided with a steering chute D. The sliding direction of the steering chute D is parallel to the axial direction of the fixing hole. The other connecting end of the left ring D and the right ring D is provided with a steering slider D that cooperates with the steering chute D. The steering slider D is circular and can move up and down along the steering chute D and also rotate circumferentially along the axis of the steering slider D within the steering chute D.

[0019] The rod channel is an open channel, and the cross-sectional area is an open non-closed structure. The second rod can be inserted into the rod channel from the opening of the open channel.

[0020] For some cases where the vertebral body deviates far, the relative position of the sleeve fixed on the anchor point will be relatively far. Although the aforementioned adjustable reinforcing ring expands the rod channel to a certain extent, for such special cases, rod passing is still difficult. The rod channel being an open channel with an open non-closed cross-sectional area can avoid the difficulties brought by rod passing and make the intraoperative operation more convenient.

[0021] The usage method of the spinal coplanar orthopedic connection assembly described in any one of the above, includes the following steps: (a) Install the sleeve onto the anchor point; (b) Put the reinforcing rings on the upper part of the sleeve, and place the second rod into the rod channel at the right end of the reinforcing ring; (c) Align the reinforcing rings in a straight line through the second rod. For the cases of anchor point offset and certain rotation, select different reinforcing rings for cooperation. Since the left end of the reinforcing ring is connected to the upper part of the sleeve, a straight line is also formed at the upper end of the sleeve; (d) Pass the first rod through the middle of the upper part of each sleeve, press down the first rod, so that the connection part between the lower end of the sleeve and the anchor point also forms a straight line, and pull the anchor point back to the normal position in a coplanar manner.

[0022] Compared with the prior art, the present invention has the following beneficial effects: The spinal coplanar orthopedic connection assembly and its usage method designed by the present invention are for the case of scoliosis. The present invention improves the problem of high rod-passing difficulty in the operation of the traditional double-rod coplanar orthopedic system in the prior art. In the improved technical solution of the present invention, the reinforcing ring connects the first rod and the second rod. Through the cooperation of the reinforcing ring, the sleeve and the second rod, the rod-passing of the first rod is completed, so that a straight line is also formed at the connection part between the lower end of the sleeve and the vertebral body. According to various complex vertebral movements, different reinforcing rings are selected for correction, reducing the rod-passing difficulty, improving the surgical efficiency, pulling the vertebral body back to the normal position in a coplanar manner, forming a non-coplanar angle between the axes, and making the first rod and the second rod cross-fixed in multiple axes in the three-dimensional space.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] In view of the irregularity and randomness of the displacement of the vertebrae with scoliosis, the present invention can combine and match different reinforcing rings as needed to reduce the difficulty of threading the rod (the first rod), so as to perform orthopedic correction for various complex vertebral movements and pull the vertebrae back to the normal position in a coplanar manner.

[0027] Specific Embodiment 1: In this embodiment, 4 types of reinforcing rings (Reinforcing Ring A3, Reinforcing Ring B4, Reinforcing Ring C5, Reinforcing Ring D6) are used in cooperation with the sleeve 7. The installation positions and sequences of the 4 types of reinforcing rings (Reinforcing Ring A3, Reinforcing Ring B4, Reinforcing Ring C5, Reinforcing Ring D6) described in this embodiment are only examples and do not represent the only one. The 4 types of reinforcing rings can be adjusted in position and sequence according to actual needs.

[0028] Please refer to Figures 1-12 , the spinal coplanar orthopedic connection assembly includes at least one sleeve 7. The lower part 73 of the sleeve is connected to the anchor point on the vertebra. In this embodiment, the anchor point refers to the fixing nail (not shown in the drawings) that has been driven into the abnormal position of the human body on the vertebra. There is a nail seat on the fixing nail, and the sleeve 7 is installed on the nail seat of the fixing nail. The fixing nail is used as the anchor point and is driven into the vertebra that needs to be adjusted in the future. The outer wall of the upper part 72 of the sleeve is sleeved with a reinforcing ring. The reinforcing rings (Reinforcing Ring A3, Reinforcing Ring B4, Reinforcing Ring C5, Reinforcing Ring D6) include fixing holes (31, 41, 51, 61) and rod channels (33, 43, 53, 63). The fixing holes (31, 41, 51, 61) cooperate with the upper part 72 of the sleeve, and the rod channels (33, 43, 53, 63) are used to accommodate the second rod 2. The axes of the fixing holes (31, 41, 51, 61) and the rod channels (33, 43, 53, 63) on each reinforcing ring are in a skew relationship in space. The first rod 1 passes through the middle of the upper part 72 of the sleeve.

[0029] In the prior art, in the case of scoliosis, the use of the traditional double-rod coplanar orthopedic system for threading the rod during the operation will cause certain troubles to the doctor, and the difficulty of threading the rod is high. However, in the improved technical solution of the present invention, the reinforcing rings (Reinforcing Ring A3, Reinforcing Ring B4, Reinforcing Ring C5, Reinforcing Ring D6) connect the first rod 1 and the second rod 2. Through the cooperation of the reinforcing rings (Reinforcing Ring A3, Reinforcing Ring B4, Reinforcing Ring C5, Reinforcing Ring D6), the sleeve 7 and the second rod 2, the threading of the first rod 1 is completed, so that the connection part between the lower end of the sleeve 7 and the vertebra also forms a straight line, and the vertebra is pulled back to the normal position in a coplanar manner, and a non-coplanar angle is formed between the axes, so that the first rod 1 and the second rod 2 are cross-fixed in multiple axes in the three-dimensional space.

[0030] The sleeve 7 includes a cylinder body 71. On both sides of the upper part 72 of the sleeve, there are upper sleeve grooves 74, and on both sides of the lower part 73 of the sleeve, there are lower sleeve grooves 75. The fixing holes (31, 41, 51, 61) and the rod body channels (33, 43, 53, 63) are respectively located at both ends of the reinforcing ring. The fixing holes (31, 41, 51, 61) and the rod body channels (33, 43, 53, 63) are through structures along their respective axes. The second rod 2 sequentially passes through the rod body channels (33, 43, 53, 63) on the right side of the reinforcing ring. Through the second rod 2, the reinforcing rings are connected in series and on the same straight line. Then, the first rod 1 is passed through the upper sleeve groove 74 of the upper part 72 of the sleeve, and the first rod 1 is pressed down to make the connection part between the lower part 73 of the sleeve and the vertebral body also form a straight line. The sleeve 7 is a prior art and is a minimally invasive sleeve.

[0031] On the inner walls of the fixing holes (31, 41, 51, 61) of the 4 kinds of reinforcing rings, there are guide blocks (34, 44, 54, 64), which cooperate with the upper sleeve groove 74. The rod body channels (33, 43, 53, 63) all include a first side (35, 47, 57, 67). The first side (35, 47, 57, 67) is arc-shaped, and the radius of curvature of the first side (35, 47, 57, 67) matches the diameter of the second rod 2. The remaining edges are free contours without constraints.

[0032] The cooperation between the guide blocks (34, 44, 54, 64) and the upper sleeve groove 74 can provide a clear movement trajectory for the reinforcing ring, ensure movement along a predetermined path, and avoid deviation or dislocation; it is convenient for quick insertion and extraction and simplifies the installation process; the contact surfaces between the guide blocks (34, 44, 54, 64) and the upper sleeve groove 74 provide multi-point support, reduce vibration or shaking during movement, and enhance the structural stability. The cross-sectional area shape of the rod body channel is designed separately. For the first side (35, 47, 57, 67) of the rod body channel (33, 43, 53, 63), the first side (35, 47, 57, 67) is the cross-sectional profile line of the inner wall on the side of the rod body channel (33, 43, 53, 63) close to the fixing hole (31, 41, 51, 61). The first side (35, 47, 57, 67) is arc-shaped, and the radius of curvature of the first side (35, 47, 57, 67) matches the diameter of the second rod 2. Finally, the second rod 2 is limited to the side of the rod body channel (33, 43, 53, 63) close to the fixing hole (31, 41, 51, 61). Therefore, for the stability of the limitation of the second rod 2, the remaining edges are free contours without constraints, which can realize the subsequent contour design of various rod body channels (33, 43, 53, 63) and make the reinforcing ring adaptable to more occasions.

[0033] Damping screw threaded holes are provided on the hole walls of the fixing holes (31, 41, 51, 61) of the four types of reinforcing rings. The damping screw threaded holes communicate with the fixing holes (31, 41, 51, 61) and are used to cooperate with damping screws (32, 42, 52, 62) to prevent the reinforcing rings from slipping off the sleeve 7.

[0034] The four types of reinforcing rings are a basic reinforcing ring and adjustable reinforcing rings. The basic reinforcing ring is Reinforcing Ring A3, and the adjustable reinforcing rings are Reinforcing Ring B4, Reinforcing Ring C5, and Reinforcing Ring D6. The fixing hole on the left side of the reinforcing ring is for passing a rod, i.e., the first rod 1, and the rod body channel on the right side of the reinforcing ring is for accommodating the second rod 2.

[0035] The rod body channel is a closed channel with a closed cross-sectional area.

[0036] As Figure 2 and Figure 3 shown, Reinforcing Ring A3 includes a fixing hole A31 on the left side and a rod body channel A33 on the right side. A damping screw threaded hole adapted to the damping screw A32 is provided on the side wall of the fixing hole A31. The damping screw threaded hole communicates with the fixing hole A31. By adjusting the damping screw A32, it is possible to prevent Reinforcing Ring A from slipping off the sleeve 7. A guide block A34 is provided on the side wall of the fixing hole A31 along the axial direction of the fixing hole A31. The guide block A34 cooperates with the upper sleeve groove 74 of the sleeve 7 to install Reinforcing Ring A3 on the upper part 72 of the sleeve. The rod body channel A33 is a closed channel with a closed cross-sectional area in the form of a hole structure, and its size matches that of the second rod.

[0037] As Figure 4 and Figure 5 shown, Reinforcing Ring B4 includes a fixing hole B41 on the left side and a rod body channel B43 on the right side. A damping screw threaded hole adapted to the damping screw B42 is provided on the side wall of the fixing hole B41. The damping screw threaded hole communicates with the fixing hole B41. By adjusting the damping screw B41, it is possible to prevent Reinforcing Ring B from slipping off the sleeve 7. A guide block B44 is provided on the side wall of the fixing hole B41 along the axial direction of the fixing hole B41. The guide block B44 cooperates with the upper sleeve groove 74 of the sleeve 7 to install Reinforcing Ring B4 on the upper part 72 of the sleeve.

[0038] The rod body channel B43 is a closed channel. The inner wall on the left side of the rod body channel B43 is an arc-shaped first side B47, and the shape formed by the remaining edges can increase the movement range of the second rod 2. It has a closed cross-sectional area in the form of a special-shaped hole structure. In the middle part of the special-shaped hole structure, the distance between the contour lines is larger than that of the first side B47, and the rightmost contour line is a mirror image of the first side. Compared with Reinforcing Ring A3, the rod body channel B43 on the right side of Reinforcing Ring B is larger, making it more convenient for the second rod 2 to pass through.

[0039] The rod body channel B43 is provided with a pushing block B45 and a push rod screw B46. The pushing block B45 and the push rod screw B46 are fixedly connected. The pushing block B45 is inside the rod body channel B43. The push rod screw B46 and the push rod threaded hole opened on the wall of the rod body channel cooperate with each other. By rotating the push rod screw B46, the pushing block B45 moves back and forth linearly in the rod body channel B43, and the pushing block B45 does not rotate with the push rod screw B46. The surface of the pushing block B45 in contact with the second rod is arc-shaped, which can increase the contact area between the pushing block B45 and the second rod 2 and ensure the stability of the effect of pressing the second rod 2 by the pushing block B45. More optimally, in order to ensure that the moving track of the push rod B45 does not deviate, sliding grooves B48 are symmetrically provided on the side walls of the rod body channel B43. The two sides of the pushing block B45 are along the direction of the sliding grooves B48 and cooperate with the push rod screw B46 to realize back-and-forth movement.

[0040] As Figure 6 and Figure 7 shown, the reinforcing ring C5 includes a fixing hole C51 on the left side and a rod body channel C53 on the right side. The side wall of the fixing hole C51 is provided with a damping screw threaded hole adapted to the damping screw C52. The damping screw threaded hole is communicated with the fixing hole C51. By adjusting the damping screw C52, the reinforcing ring C is prevented from slipping off the sleeve 7. A guiding block C54 is provided on the side wall of the fixing hole C51 along the axial direction of the fixing hole C51. The guiding block C54 cooperates with the sleeve upper groove 74 of the sleeve 7 to install the reinforcing ring C5 to the upper part 72 of the sleeve.

[0041] The rod body channel C53 is an open channel. The left inner wall of the rod body channel C53 is an arc-shaped first side C57, and the shape formed by the remaining edges can increase the activity range of the second rod 2. The cross-sectional area is an open non-closed structure, and the second rod 2 can be inserted into the rod body channel C53 from the opening of the open channel.

[0042] As shown in the figure, the cross-sectional profile of the rod body channel C53 is an open non-closed structure (that is, the rod body channel C53 is a rod clamping groove structure in this embodiment), including a first side C57, a rectangle in the middle, and a mirror image of the first side on the right, and there is an opening at the lower end of the rod body channel C53.

[0043] The rod channel C53 is provided with a pushing block C55 and a push rod screw C56. The pushing block C55 and the push rod screw C56 are fixedly connected. The pushing block C55 is inside the rod channel C53. The push rod screw C56 and the push rod threaded hole opened on the wall of the rod channel C53 cooperate with each other. By rotating the push rod screw C56, the pushing block C55 moves back and forth linearly in the rod channel C53, and the pushing block C55 does not rotate along with the push rod screw C56. The surface of the pushing block C55 in contact with the second rod 2 is arc-shaped, which can increase the contact area between the pushing block C55 and the second rod 2 and ensure the stability of the effect of pressing the second rod 2 by the pushing block C55. More optimally, in order to ensure that the moving track of the push rod C55 does not deviate, a sliding groove C58 is provided on one side wall of the rod channel C53, and a convex block is provided on one side of the pushing block C55. The convex block moves back and forth along the direction of the sliding groove C58 in cooperation with the push rod screw C56.

[0044] For some cases where the vertebrae deviate far away, the aforementioned reinforcing rings A and B may still have poor rod-passing effects. Although the aforementioned adjustable reinforcing ring (reinforcing ring B4) expands the rod channel to a certain extent, in some cases where the vertebrae deviate far away, the relative positions of the sleeves 7 fixed on the anchor points (fixing screws) are far apart. At this time, passing the rod is still difficult. The rod channel C53 of the improved reinforcing ring C5 is an open channel, and the cross-sectional area is an open non-closed structure. Compared with the reinforcing ring A, the rod channel C53 is larger. At this time, the difficulty brought by passing the rod can be avoided, and the second rod 2 can more easily enter the rod channel C53, making the intraoperative operation more convenient.

[0045] As Figures 8 to 12 shown, the reinforcing ring D6 is a split and detachable structure, including a left ring D611 and a right ring D612. The left ring D611 is the end where the fixing hole D61 is located in the reinforcing ring D6, and the right ring D612 is the end where the rod channel D63 is located in the reinforcing ring D6. The right ring D612 and the left ring D611 are assembled together so that the right ring D612 can rotate around the left ring D611 to a certain extent.

[0046] The side wall of the fixing hole D61 is provided with a damping screw threaded hole adapted to the damping screw D62. The damping screw threaded hole is communicated with the fixing hole D61. By adjusting the damping screw D62, the reinforcing ring D6 is prevented from slipping off the sleeve 7. The side wall of the fixing hole D61 is provided with a guiding block D64 along the axial direction of the fixing hole D61. The guiding block D64 cooperates with the sleeve upper groove 74 of the sleeve 7 to install the reinforcing ring D6 on the upper part 72 of the sleeve.

[0047] A steering groove D69 is provided at one of the connected ends of the left ring D611 and the right ring D612. The sliding direction of the steering groove D69 is parallel to the axial direction of the fixed hole D61. A steering slider D610 is provided at the other connected end of the left ring D611 and the right ring D612 to cooperate with the steering groove D69. The steering slider D610 includes a disc and a connecting block. The disc slides into the steering groove D69 from the upper opening. The diameter of the connecting block is smaller than that of the disc. The disc and the fixed hole D61 are connected so that the disc and the fixed hole D61 move as one. The steering groove D69 is provided with limiting edges on both sides parallel to the axial direction of the fixed hole D61, which limits the disc from entering or leaving the steering groove D69 from these two directions. The front and rear surfaces of the disc in the thickness direction are in contact with the corresponding inner walls of the steering groove D69. The right ring D612 has a slot 691 structure at the steering chute D. The slot 691 is symmetrically arranged on the two side walls of the steering chute D69. The two opposite faces of the slot are provided with depressions. The depressions cooperate with the connecting block of the steering slider D610. When in use, the connecting block is inserted into the depression of the slot 691, and the connecting block can rotate in the slot 691. The steering slider D610 at the right end of the left ring D611 is inserted into the steering chute D69 of the left ring D611 through the tooling, and the connecting block of the steering slider D69 is pressed into the slot 691 structure of the right ring 612. The left ring D611 disc restricts the left ring D611 from moving perpendicular to the end face of the disc. After the right ring D612 slot 691 structure is pressed into the tooling, it restricts the left ring D611 from moving along the direction of the steering chute D69. Therefore, the left ring D611 can only rotate along the axis of the connecting block relative to the right ring D612.

[0048] On the one hand, under the external force applied to the reinforcing ring D6, the axes of the disc and the connecting block coincide, and the disc can smoothly rotate along its own axis; on the other hand, after rotating to the specified position, the disc must remain firmly at this position and will not move by itself due to its own gravity or other interference factors. In order to achieve the above functions, after comprehensive consideration, it is decided to use the front and rear surfaces of the disc in the thickness direction to contact the corresponding inner walls of the rotating chute D69, so that the outer diameter of the disc and the inner diameter of the chute form a just right interference; the connecting block is inserted into the depression of the slot 69. In this way, when the disc is driven by normal external force, the resistance generated by the interference will not hinder the circumferential rotation of the disc and the connecting block; the disc will not move forward and backward along the axis of the disc in the rotating chute D69, causing shaking. When the external force is removed, the friction or interference fit between the slot 69 and the connecting block is sufficient to ensure that the connecting block stays firmly in the position after rotation, effectively preventing its self-displacement, thereby ensuring the position of the disc. The steering slider D610 can move up and down along the steering slot D69 (the movement here does not mean free movement after installation, but relative movement when installing and removing the disc and the steering slot D69), and can also rotate circumferentially along the axis of the steering slider D in the steering slot D.

[0049] The rod body channel D63 is a closed channel. The left inner wall of the rod body channel D63 is the arc-shaped first side D67, and the shape formed by the remaining edges can increase the movement range of the second rod 2. For example, it is a special-shaped hole structure with a closed cross-section. The special-shaped hole structure can adopt the structure in the reinforcing ring B4, or the distance between the contour lines of the other contours of the special-shaped hole structure except the first side is increased compared with the first side D67 (both the length and width are increased). Compared with the rod body channels B43 on the right side of the reinforcing ring A3 and the reinforcing ring B4, the Figure 8 and 9 the structure of the special-shaped hole in, the rod body channel D63 is larger and more convenient for the second rod 2 to penetrate.

[0050] The rod body channel D63 is provided with a push block D65 and a push rod screw D66. The push block D65 and the push rod screw D66 are fixedly connected. The push block D65 is inside the rod body channel D63. The push rod screw D66 and the push rod threaded hole opened on the wall of the rod body channel cooperate with each other. By rotating the push rod screw D66, the push block D65 moves back and forth linearly in the rod body channel D63, and the push block D65 does not rotate with the push rod screw D66. The surface of the push block D65 in contact with the second rod 2 is arc-shaped, which can increase the contact area between the push block D65 and the second rod 2 and ensure the stability of the effect of pressing the second rod 2 by the push block D65. More optimally, in order to ensure that the movement track of the push rod B45 does not deviate, the side walls of the rod body channel D63 are symmetrically provided with sliding grooves D68, and both sides of the push block D65 are along the direction of the sliding grooves D68, and cooperate with the push rod screw D66 to realize back and forth movement.

[0051] Compared with the reinforcing ring A3, the shape formed by the remaining edges of the rod body channels (43, 53, 63) on the right side of the adjustable reinforcing rings (reinforcing ring B4, reinforcing ring C5, reinforcing ring D6) can increase the movement range of the second rod 2, make the rod body channels of the adjustable reinforcing rings larger and more convenient for the second rod 2 to penetrate. At the same time, the push blocks (45, 55, 65) and the push rod screws (46, 56, 66) can push the second rod 2 to move in the rod body channels (43, 53, 63) so that the adjustable reinforcing rings are on the same straight line.

[0052] When the vertebral body rotates a certain angle along the Y axis, the rod-passing hole of the traditional reinforcing ring will form a certain angle with the second rod 2. When the angle is too large, it will even lead to the failure of rod passing. The structure of the reinforcing ring D6 makes up for the generated angle by rotating the right ring D612, thereby solving the problem of rod passing in the case of the rotation of the vertebral body along the Y axis.

[0053] A method for using a spinal coplanar orthopedic connection assembly includes the following steps: (a) Install each sleeve on the anchor point (the nail seat of the fixing nail) (the fixing nail has been driven into the abnormal vertebral body in the human body before). (b)Select a reinforcing ring that is more suitable for the rod channel according to the offset of the vertebral body. Put each reinforcing ring on the upper part 72 of the sleeve, adjust the damping screws (32, 42, 52, 62) to prevent the reinforcing ring from slipping off the sleeve 7, and place the second rod 2 into the rod channel at the right end of the reinforcing ring. (c)In the adjustable reinforcing ring, the push rod screws (46, 56, 66) can be adjusted to drive the push blocks (45, 55, 65) to push the second rod 2 so that the reinforcing rings are in the same straight line. For the case of anchor point offset and certain rotation, different reinforcing rings are selected for cooperation. Since the left end of the reinforcing ring is connected to the upper part of the sleeve, a straight line is also formed at the upper end of the sleeve. (d)Pass the first rod 1 through the middle of the upper part 72 of each sleeve, press down the first rod 1 so that the connecting part between the lower end of the sleeve and the anchor point also forms a straight line, and pull the anchor point back to normal in a coplanar manner.

[0054] As mentioned above for the operation of the anchor point, the anchor point (fixing nail) has been driven into the abnormal vertebral body of the human body. Therefore, the operation on the anchor point also acts on the vertebral body, and finally, the vertebral body is pulled back to normal in a coplanar manner.

[0055] Figures 2 to 9 are reinforcing rings of different structures. Figure 2 、 Figure 3 is the reinforcing ring A3, which is the most basic structure of the reinforcing ring. Figure 4 、 Figure 5 is the reinforcing ring B4, which increases the push rod structure and enlarges the rod channel B43. Figure 6 、 Figure 7 is the reinforcing ring C5. Figure 8 and Figure 9 is the reinforcing ring D6. For the case of large vertebral body offset and certain rotation, the reinforcing rings are respectively designed into the structures of lower opening and left and right rings, so as to perform orthopedic correction for various complex vertebral body movements. Specific embodiments

[0056] The difference between this specific embodiment and the specific embodiment 1 lies in the combination of the reinforcing rings. In this specific embodiment, only the reinforcing ring A3 is used. First, install the sleeve 7 on the nail seat of the fixing nail. At this time, the fixing nail has been driven into the abnormal vertebral body of the human body. Put each reinforcing ring A3 on the upper part of the sleeve 7, adjust the damping screws (32, 42, 52, 62) to prevent the reinforcing ring A3 from slipping off the sleeve 7, and pass the second rod 2 through the rod channel A33 at the right end of the reinforcing ring A3. The second rod 2 makes the reinforcing ring A3 in the same straight line. Since the left end of the reinforcing ring A3 is connected to the upper part 72 of the sleeve, a straight line is already formed at the upper end of the sleeve 7 at this time. Then pass the first rod 1 through the middle of the upper part 72 of each sleeve, press down the first rod, so that the connecting part between the lower end of the sleeve 7 and the vertebral body also forms a straight line. Therefore, the vertebral body is pulled back to the normal position in a coplanar manner. Specific Embodiment

[0057] The difference between this specific embodiment and Specific Embodiment 1 lies in the combination of the reinforcing rings. This specific embodiment only uses the reinforcing ring B4. In addition to the basic functions of the reinforcing ring A, the rod body channel B43 on the right side of the reinforcing ring B4 is larger. Usage process: First, install the sleeve 7 on the nail seat of the fixing nail. At this time, the fixing nail has been driven into the vertebral body at the abnormal position of the human body. Put the reinforcing rings B4 on the upper part 72 of the sleeve, adjust the damping screw 42 to prevent the reinforcing ring B4 from slipping off the sleeve 7, and insert the second rod 2 through the rod body channel B43 at the right end of the reinforcing ring B4. Then adjust the push rod screw B46 on the reinforcing ring B4 to push the rod 2 so that the reinforcing rings B4 are in a straight line. Since the left end of the reinforcing ring B4 is connected to the upper part 72 of the sleeve, a straight line is already formed at the upper end of the sleeve 7 at this time. Then insert the first rod 1 through the middle of the upper parts 72 of each sleeve, and press down the first rod 1 so that the connecting part between the lower end of the sleeve 7 and the vertebral body also forms a straight line. Therefore, the vertebral body is pulled back to the normal position in a coplanar manner. Specific Embodiment

[0058] The difference between this specific embodiment and Specific Embodiment 3 lies in the combination of the reinforcing rings. This specific embodiment only uses the reinforcing ring C5. In addition to the basic functions of the reinforcing ring A, the rod body channel C53 on the right side of the reinforcing ring C5 is larger and has a lower opening. Usage process: Put the reinforcing rings C5 on the upper part 72 of the sleeve, adjust the damping screw 52 to prevent the reinforcing ring C5 from slipping off the sleeve 7, and snap the second rod 2 into the lower opening at the right end of the rod body channel C53 of the reinforcing ring C5. The reinforcing ring C5 is designed with a lower opening structure. For some cases where the vertebral body deviates far, the lower opening structure of the reinforcing ring C5 and the rod body channel C53 are also enlarged compared to the reinforcing ring A, avoiding the difficulty of threading the rod and making the intraoperative operation easier. Then adjust the push rod screw C56 on the reinforcing ring C5 to push the rod 2 so that the reinforcing rings C5 are in a straight line. The usage process and other details not described are the same as those in Specific Embodiment 3. Specific Embodiment

[0059] The difference between this specific embodiment and Specific Embodiment 3 lies in the combined matching of the reinforcing rings. In this specific embodiment, only the reinforcing ring D6 is used. Besides having the basic functions of the reinforcing ring A, the reinforcing ring D6 also has a larger rod channel D63 on the right side of the reinforcing ring D6, and the right ring D612 can rotate around the left ring D611 to a certain extent. Usage process: Assemble the left ring D611 and the right ring D612 of the reinforcing ring D6 together, slip each reinforcing ring D6 onto the upper part 72 of the sleeve, adjust the damping screw 52 to prevent the reinforcing ring C5 from slipping off the sleeve 7. When the vertebral body rotates to a certain extent along the Y-axis, the right ring D612 can rotate around the left ring D611 to a certain extent. Adjust the relative angle between the right ring D612 and the left ring D611, and pass the second rod 2 through the rod channel D63 at the right end of the reinforcing ring D6. Then, adjust the push rod screw D66 on the reinforcing ring D6 to push the rod 2 so that the reinforcing rings D6 are in a straight line.

[0069] Specific Embodiment 15: The difference between this specific embodiment and 1, 5, 8, 10, 11, 13, or 14 lies in the change in the structure of the connection between the left ring D and the right ring D of the reinforcing ring D.

[0070] The reinforcing ring D6 is a detachable split structure, including a left ring D and a right ring D. The left ring D is the end where the fixing hole D61 of the reinforcing ring D6 is located, and the right ring D is the end where the rod body channel D63 of the reinforcing ring D6 is located. The right ring D and the left ring D are assembled together so that the right ring D can rotate around the left ring D to a certain extent.

[0071] One of the connecting ends of the left ring D and the right ring D is provided with a steering chute D69, and the sliding direction of the steering chute D69 is parallel to the axial direction of the fixing hole D61. The other connecting end of the left ring D and the right ring D is provided with a steering slider D610 that cooperates with the steering chute D69. The steering slider D610 includes a disc and a connecting block. The disc slides into the steering chute D69 from the upper opening. The diameter of the connecting block is smaller than that of the disc. The disc is connected to the fixing hole D61 so that the disc and the fixing hole D61 move integrally. The two sides of the steering chute D69 parallel to the axial direction of the fixing hole D61 are provided with limiting edges, and the lower end of the steering chute D69 is also provided with a limiting edge, which limits the disc from entering or leaving the steering chute D69 in these three directions. There is an interference fit between the thickness of the disc and the depth of the steering chute D69. On the one hand, under the action of an externally applied force on the reinforcing ring D6, the disc can smoothly rotate circumferentially along the disc. On the other hand, when rotated to a specified position, the disc must be firmly held in place and will not displace itself due to its own gravity or other interference factors. To achieve the above functions, after comprehensive consideration, a design scheme of interference fit between the disc and the rotating chute D69 is decided to form a proper interference amount between the outer diameter of the disc and the inner diameter of the chute. In this way, when the disc is driven by a normal external force, the resistance generated by this interference amount is not sufficient to hinder the circumferential rotation of the disc; and when the external force is withdrawn, the strong frictional force generated by the interference fit is sufficient to ensure that the disc stays steadily in the rotated position, effectively preventing it from displacing itself. The steering slider D610 can move up and down along the steering chute D69 and can also rotate circumferentially along the axis of the steering slider D within the steering chute D.
