Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of spinal fracture treatment, and specifically provides a highly adaptable implant for spinal fracture treatment. Background Art
[0002] Spinal fractures are common and serious traumas in orthopedics. Their treatment requires ensuring the reduction, fixation, and fusion of the fracture site to promote fracture healing and the restoration of spinal function. Traditional treatment methods such as plaster fixation and traction have certain effects, but they have problems such as inaccurate reduction, unstable fixation, and long rehabilitation periods. With the continuous progress of materials science, more and more new materials are being applied to the manufacture of medical devices. These materials not only have excellent mechanical properties and biocompatibility but also can meet the requirements of medical devices for characteristics such as lightweight, high strength, and corrosion resistance. In the field of spinal implants, the application of these technologies has made the design of implants more in line with the ergonomic principle and better adapted to the spinal anatomical structure and fracture conditions of patients. Such implants are manufactured using advanced materials and technologies and have characteristics such as high customization, versatility, and biocompatibility. It can be designed and manufactured according to the specific conditions of patients, providing stable support and reduction effects, while reducing the surgical trauma and infection risks, and promoting the rehabilitation of patients and improving the treatment effect.
[0003] During the operation, it is necessary to drill a hole in the spine, and then place the implant into the internal hole of the spine. The implant is opened to support the internal hole of the spine. Existing implants usually inject bone cement into the spine through the notches on the surface of the connecting rod. When injecting through the notches, the bone cement inside the spine is extruded and filled from the inside out. This not only increases the pressure of the bone cement on the spine but also causes insufficient filling in some areas of the spine, making the bone cement unable to be evenly distributed between the implant and the bone tissue. And when the opening degree of the implant is relatively large, the amount of bone cement filling also needs to be increased. In some areas, there may be too much bone cement filling, increasing the pressure on the surrounding tissues; while in some areas, there may be insufficient filling, affecting the stability of the implant.

Detailed implementation manners
[0034] 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.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0035] Please refer to Figures 1-10 , the present invention provides a technical solution: a highly adaptable implant for the treatment of spinal fractures, including a fixed platform 1. The right end of the fixed platform 1 is rotatably connected to a connecting rod 2. A support rod 3 is installed at the right end of the fixed platform 1. The top of the support rod 3 is installed with a top plate 5. A retaining tube A 6 is slidably limited inside the connecting rod 2. A retaining tube B 7 is slidably limited inside the retaining tube A 6. A connecting tube 8 and a rotating tube 9 are installed inside the connecting rod 2. A baffle 10 is installed inside the connecting rod 2. A sliding platform 12 is slidably limited inside the connecting tube 8;
[0036] A moving adjustment assembly 11, the moving adjustment assembly 11 includes an oil chamber A 111 and an oil chamber B 112 opened inside the connecting tube 8. A pull rod 113 is installed on the inner wall of the retaining tube A 6. A piston block 114 is slidably limited inside the oil chamber A 111. The right end of the pull rod 113 penetrates through the connecting tube 8 and is connected to the side end of the piston block 114. A piston rod 115 is slidably limited inside the oil chamber B 112. The right end of the piston rod 115 is arranged at the left end of the rotating tube 9. The oil chamber A 111 is communicated with the oil chamber B 112. When injecting bone cement into the spine, rotating the rotating tube 9 will gradually contract the retaining tube A 6 towards the surface of the retaining tube B 7, gradually expanding the notch on the surface of the connecting rod 2, enabling the bone cement to be gradually injected from the inside to the outside, filling the internal space and then gradually diffusing outwards. An expansion adjustment assembly 13 is installed inside the left end of the connecting rod 2 and inside the connecting tube 8.
[0037] As an implementation manner of the present invention, the connecting rod 2 is composed of two sections of hollow tubes combined. The surface of the left hollow tube of the connecting rod 2 is provided with a notch. The surface of the right hollow tube of the connecting rod 2 is provided with threads. The inside of the hollow tube of the connecting rod 2 is provided with internal threads. The design of the hollow tube allows the bone cement to be injected from the inside and ejected from the surface notch;
[0038] As an implementation manner of the present invention, the number of the support rods 3 and the top plate 5 is two groups. The two groups of support rods 3 and the top plate 5 are symmetrically distributed at the upper and lower ends of the connecting rod 2. An adjustment table 4 is installed at the right end of the support rod 3. The adjustment table 4 is meshed with the threads on the surface of the right hollow tube of the connecting rod 2. Rotating the connecting rod 2 inside the adjustment table 4 can adjust the opening degree of the support rod 3. The design of the two groups of support rods 3 and the top plate 5 can support the internal space of the spine;
[0039] As an implementation manner of the present invention, the right end of the retaining tube B 7 is connected to the right end inside the left hollow tube of the connecting rod 2. An annular groove is opened inside the retaining tube A 6. The outer diameter of the annular groove is the same as the outer wall size of the retaining tube B 7, and the inner diameter of the annular groove is the same as the inner wall size of the retaining tube B 7. A spring is installed inside the annular groove, and the other end of the spring is connected to the end of the retaining tube B 7. The retaining tube B 7 is slidably limited inside the annular sliding groove of the retaining tube A 6;
[0040] As an implementation manner of the present invention, the connecting pipe 8 is fixed to the left side inside the hollow pipe on the right side of the connecting rod 2, and the rotating pipe 9 is installed on the right side of the connecting pipe 8. The surface of the rotating pipe 9 is provided with threads and meshes with the internal threads inside the hollow pipe of the connecting rod 2. Rotating the rotating pipe 9 in the connecting pipe 8 will cause it to move away from the fixed platform 1;
[0041] As an implementation manner of the present invention, an annular groove is opened at the left end of the rotating pipe 9, and the right end of the piston rod 115 is slidably limited inside the annular groove. When the rotating pipe 9 rotates in the connecting platform, the rotating platform can also pull the piston rod 115 to move it away from the fixed platform 1;
[0042] As an implementation manner of the present invention, the expansion adjustment assembly 13 includes a mounting plate 131 installed at the bottom of the oil chamber A111. The top of the mounting plate 131 is installed with a piston plate 132 through a spring. The bottom of the left end of the piston plate 132 is installed with a pressing block 133. An elastic block 134 is installed inside the piston block 114 through a spring. A rotating cylinder 135 is fixedly installed at the right end of the fixed platform 1. A slider 136 is slidably limited inside the rotating cylinder 135. A push rod 137 is installed at the right end of the slider 136. The other end of the push rod 137 is connected to the left end of the sliding table 12. An oil chamber C138 is opened inside the connecting pipe 8 at the side of the oil chamber A111. The expansion adjustment assembly 13 can adjust the speed at which the notch on the surface of the connecting rod 2 expands according to the expansion degree of the support rod 3, so that the doctor can accurately control the expansion speed of the notch on the surface of the connecting rod 2 according to the surgical needs, thereby adjusting the injection speed of the bone cement;
[0043] The bone cement inside the spine is extruded and filled from the inside outwards. This will not only increase the pressure of the bone cement on the spine, but also cause insufficient filling in some areas of the spine. And when the opening degree of the implant is relatively large, the amount of bone cement filled also needs to be increased. The specific implementation manner is as follows. First, insert the implant into the spine. Then rotate the connecting rod 2. The fixed platform 1 and the adjustment platform 4 squeeze the support rod 3, so that the support rod 3 drives the top plate 5 to open. The top plate 5 supports the inside of the spine. Then inject bone cement into the connecting rod 2, and make it inject into the spine from the surface notch. Rotate the rotating pipe 9 inside the connecting rod 2. The rotation of the rotating pipe 9 will move to the right. The rightward movement of the rotating pipe 9 pulls the piston rod 115 to move outwards. The piston rod 115 moves horizontally outwards to inject the oil inside the oil chamber B112 into the oil chamber A111. The oil inside the oil chamber A111 pushes the piston block 114 to slide horizontally inwards. The sliding of the piston block 114 will pull the pull rod 113, and the pull rod 113 drives the pipe A6 to move to the right. The pipe A6 contracts on the surface of the pipe B7, and the notch on the surface of the support rod 3 gradually expands;
[0044] The rotation of the connecting rod 2 drives the slider 136 to slide in a limited manner within the rotating cylinder 135. The slider 136 drives the ejector rod 137 to push the sliding table 12 to slide within the connecting pipe 8. The sliding of the sliding table 12 applies pressure to the extrusion block 133, causing the piston plate 132 to slide vertically within the oil chamber A111. The piston plate 132 squeezes the elastic block 134, causing it to contract into the piston block 114, and squeezing the oil within the oil chamber A111 into the oil chamber C138. The rotating pipe 9 rotates within the connecting rod 2. The rotation of the rotating pipe 9 causes it to move to the right and pull the piston rod 115 to move outward. The outward lateral movement of the piston rod 115 injects the oil within the oil chamber B112 into the oil chamber A111. The oil within the oil chamber A111 pushes the piston block 114 to slide inward laterally. The reduction of the oil within the oil chamber A111 slows down the lateral sliding speed of the piston block 114. The inward lateral sliding of the piston block 114 pulls the pull rod 113, and the piston block 114 slows down the speed at which the pull rod 113 drives the pipe A6 to move to the right;
[0045] As an implementation manner of the present invention, the oil chamber A111 is communicated with the oil chamber C138. The communication port between the oil chamber A111 and the oil chamber C138 is in a trumpet shape from left to right. A top block 139 is installed within the communication port between the oil chamber A111 and the oil chamber C138 through a spring. The top block 139 is semi-circular. The piston plate 132 injects the oil within the oil chamber A111 into the oil chamber C138 through the communication port. When the piston rod 115 is pulled, the moving speed of the piston block 114 within the oil A will change. The semi-circular top block 139 within the communication port forms a one-way structure within the communication port, and the oil can only be injected into the oil chamber C138;
[0046] As an implementation manner of the present invention, a spiral groove is provided inside the rotating cylinder 135. The slider 136 slides in a limited manner within the spiral groove. A top rod 137 is fixedly installed at the side end of the slider 136. A baffle 10 is sleeved on the surface of the top rod 137. The bottom of the extrusion block 133 is inclined. The provision of the spiral groove within the rotating cylinder 135 causes the connecting rod 2 to drive the top rod 137 to drive the sliding table 12 to slide in a limited manner within the connecting pipe 8 when rotating, so that the convex block within the sliding table 12 applies pressure to the extrusion block 133, causing the piston plate 132 to inject the oil within the oil chamber A111 into the oil chamber C138;
[0047] Working principle: First, insert the implant into the spine. Then, rotate the connecting rod 2. The fixing platform 1 and the adjusting platform 4 squeeze the support rod 3, causing the support rod 3 to drive the top plate 5 to open. The top plate 5 supports the inside of the spine. Subsequently, inject bone cement into the connecting rod 2, and let it be injected into the spine from the surface notch. Rotate the rotating tube 9 within the connecting rod 2. When the rotating tube 9 rotates, it will move to the right. The rotating tube 9 moving to the right pulls the piston rod 115 to move outwards. The piston rod 115 moving outwards horizontally injects the oil in the oil chamber B112 into the oil chamber A111. The oil in the oil chamber A111 pushes the piston block 114 to slide inwards horizontally. The piston block 114 sliding will pull the pull rod 113, and the pull rod 113 drives the retaining tube A6 to move to the right. The retaining tube A6 contracts on the surface of the retaining tube B7, and the notch on the surface of the support rod 3 gradually expands;
[0048] The rotation of the connecting rod 2 drives the slider 136 to slide within the limit of the rotating cylinder 135. The slider 136 will drive the ejector rod 137 to push the sliding table 12 to slide within the connecting tube 8. The sliding of the sliding table 12 applies pressure to the extrusion block 133, causing the piston plate 132 to slide vertically within the oil chamber A111. The piston plate 132 squeezes the elastic block 134, causing it to contract into the piston block 114, and squeezes the oil in the oil chamber A111 into the oil chamber C138. The rotating tube 9 rotates within the connecting rod 2. When the rotating tube 9 rotates, it will move to the right and pull the piston rod 115 to move outwards. The piston rod 115 moving outwards horizontally injects the oil in the oil chamber B112 into the oil chamber A111. The oil in the oil chamber A111 pushes the piston block 114 to slide inwards horizontally. The reduction of the oil in the oil chamber A111 will slow down the horizontal sliding speed of the piston block 114. The piston block 114 sliding inwards horizontally will pull the pull rod 113, and the piston block 114 slows down the speed of the pull rod 113 driving the retaining tube A6 to move to the right.
