[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: As Figures 1-4 As shown, the present invention provides a surgical fixation device for spinal trauma in clinical orthopedics, comprising multiple mounting bases 1, an adjustment mechanism 2 on one side of each mounting base 1, a connecting mechanism 3 at one end of each adjustment mechanism 2, and a fixing mechanism 4 at one end of each of the multiple connecting mechanisms 3. The adjustment mechanism 2 includes a mounting rod 20, one end of which is fixedly connected to one side of the mounting base 1. A primary adjustment rod 21 is rotatably mounted on one end of the mounting rod 20, and a secondary adjustment rod 24 is rotatably mounted on the end of the primary adjustment rod 21 away from the mounting rod 20. A locking block 26 is fixedly mounted on one end of the secondary adjustment rod 24. A rotating frame 23 is fixedly mounted on one end of both the primary and secondary adjustment rods 21. A rotating wheel 22 is fixedly mounted on one end of both the mounting rod 20 and the primary adjustment rod 21. The rotating wheel 22 rotates and fits against the inner side of the rotating frame 23. A fastening screw 29 is inserted into one side of the rotating frame 23, and a fastening nut 27 is threaded onto one end of the fastening screw 29.

[0028] By adopting the above technical scheme, in the clinical orthopedic spinal trauma surgery, when it is necessary to adjust the device according to the position and shape of the spinal trauma of the patient, the fastening nut 27 is loosened first, and since the fastening nut 27 is in threaded cooperation with the fastening screw 29, the limiting effect of the fastening screw 29 on the rotating frame 23 and the rotating wheel 22 is released after being loosened. At this time, the primary adjusting rod 21 can be rotated, and the primary adjusting rod 21 rotates around the rotating connection point of the primary adjusting rod 21 and the mounting rod 20, and at the same time, the rotating frame 23 at one end of the primary adjusting rod 21 rotates outside the rotating wheel 22, and the rotating groove 28 provides a sliding space for the fastening screw 29, so that the primary adjusting rod 21 can be flexibly rotated. Then, the secondary adjusting rod 24 is rotated again, and the secondary adjusting rod 24 rotates around the rotating connection point of the secondary adjusting rod 24 and the primary adjusting rod 21, and the rotating frame 23 thereof also rotates outside the rotating wheel 22. By adjusting the rotation angles of the primary adjusting rod 21 and the secondary adjusting rod 24, the overall angle of the adjusting mechanism 2 can be changed, and by adjusting the relative positions therebetween, the length of the adjusting mechanism 2 can be changed. After being adjusted to a suitable position and angle, the fastening nut 27 is tightened, and the rotating frame 23 and the rotating wheel 22 are tightly fixed through the fastening screw 29, so that the length and angle of the adjusting mechanism 2 are accurately fixed, so as to adapt to different spinal trauma conditions.

[0029] A plurality of mounting holes 5 in a rectangular array are formed on one side of the mounting base 1.

[0030] By adopting the above technical scheme, the plurality of mounting holes 5 in a rectangular array formed on one side of the mounting base 1 provide multiple choices for the connection of the mounting base 1 with the skeleton or other fixed parts. The doctor can select appropriate mounting holes 5 for fixation according to the specific bone conditions and surgical needs of the patient, improve the flexibility and stability of the installation, and ensure that the mounting base 1 can be firmly fixed at the appropriate position to provide a stable foundation for the entire surgical fixation device.

[0031] The rotating frame 23 and the rotating wheel 22 are each provided with a rotating groove 28 on one side, and the inner side of the rotating groove 28 is in sliding fit with the fastening screw 29.

[0032] By adopting the above technical scheme, the rotating groove 28 provided on one side of the rotating frame 23 and the rotating wheel 22 provides an accurate sliding track for the fastening screw 29. After the length and angle of the adjusting mechanism 2 are adjusted, the fastening screw 29 can be accurately inserted into the rotating groove 28, so that the rotating frame 23 and the rotating wheel 22 can be uniformly stressed during the fastening process, avoiding the occurrence of deviation or loosening, thereby more effectively fixing the positions of the primary adjusting rod 21 and the secondary adjusting rod 24, and ensuring the adjustment accuracy and stability of the adjusting mechanism 2.

[0033] The clamping block 26 is provided with a clamping groove 25 on one side, and the clamping groove 25 is in clamping cooperation with the clamping piece 35.

[0034] By adopting the above technical scheme, the clamping groove 25 opened on one side of the clamping block 26 is clamped and matched with the clamping piece 35, so that the quick and accurate connection of the connecting seat 30 and the adjusting mechanism 2 can be realized. This clamping connection mode is simple to operate, can save time in surgery, and improves the efficiency of surgery. At the same time, the design of the clamping groove 25 increases the stability of the connection, prevents the connecting seat 30 and the clamping block 26 from accidentally separating during the surgery process, and ensures the reliability of the entire surgical fixation device.

[0035] Working principle: In the clinical orthopedic spinal trauma surgery, when it is necessary to adjust the device according to the position and shape of the patient's spinal trauma, the fastening nut 27 is loosened first. Since the fastening nut 27 is threadedly matched with the fastening screw 29, the limiting effect of the fastening screw 29 on the rotating frame 23 and the rotating wheel 22 is released after loosening. At this time, the primary adjusting rod 21 can be rotated, and the primary adjusting rod 21 rotates around the rotating connection point with the mounting rod 20. At the same time, the rotating frame 23 at one end of the primary adjusting rod 21 rotates outside the rotating wheel 22, and the rotating groove 28 provides a sliding space for the fastening screw 29, so that the primary adjusting rod 21 can be flexibly rotated. Then, the secondary adjusting rod 24 is rotated, and the secondary adjusting rod 24 rotates around the rotating connection point with the primary adjusting rod 21, and its rotating frame 23 also rotates outside the rotating wheel 22. By adjusting the rotation angles of the primary adjusting rod 21 and the secondary adjusting rod 24, the overall angle of the adjusting mechanism 2 can be changed, and by adjusting the relative positions between them, the length of the adjusting mechanism 2 can be changed. When the appropriate position and angle are adjusted, the fastening nut 27 is tightened, and the rotating frame 23 and the rotating wheel 22 are tightly fixed by the fastening screw 29, so as to realize the precise fixing of the length and angle of the adjusting mechanism 2, so as to adapt to different spinal trauma conditions.

[0036] Embodiment two: as shown in Figures 5-6 The connecting mechanism 3 includes a connecting seat 30, one side of the connecting seat 30 is fixedly provided with two clamping pieces 35, the clamping pieces 35 are clamped and connected with the clamping blocks 26, one side of the connecting seat 30 is provided with a rotating seat 31, the rotating seat 31 and the two sides of the connecting seat 30 are commonly provided with a connecting shaft 36, one side of the rotating seat 31 is fixedly provided with a connecting frame 33, the inner side of the connecting frame 33 is provided with a fixed frame 32, and the fixed frame 32 is fixedly matched with the fixing mechanism 4.

[0037] By adopting the above technical scheme, after the adjustment of the adjustment mechanism 2 is completed, the installation of the connecting mechanism 3 is carried out. The two clamping pieces 35 on one side of the connecting seat 30 are aligned with the clamping grooves 25 on the end clamping block 26 of the secondary adjustment rod 24, the connecting seat 30 is pushed with force, the clamping pieces 35 are clamped into the clamping grooves 25, the preliminary connection between the connecting mechanism 3 and the adjustment mechanism 2 is realized. Then, the connecting shaft 36 is inserted into the connecting holes 37 opened on both sides of the rotating seat 31 and the connecting seat 30, so that the rotating seat 31 can rotate relative to the connecting seat 30 around the connecting shaft 36, so that the angle of the connecting mechanism 3 can be flexibly adjusted according to the actual installation situation. Then, the fixing frame 32 is placed on the inner side of the connecting frame 33, and the fixing frame 32 and the connecting frame 33 are fixedly connected by using appropriate fixing pieces such as bolts and the like through the fixing holes 34 opened on one side of the rotating seat 31 and the connecting frame 33, so as to ensure the stability of the overall structure of the connecting mechanism 3. At this time, the connecting mechanism 3 is stably connected to the adjustment mechanism 2, and can be rotated and adjusted by a certain angle through the connecting shaft 36, so as to prepare for the subsequent connection with the fixing mechanism 4.

[0038] The connecting holes 37 are opened on both sides of the rotating seat 31 and the connecting seat 30, and the connecting holes 37 are rotationally connected with one end of the connecting shaft 36.

[0039] By adopting the above technical scheme, the connecting holes 37 opened on both sides of the rotating seat 31 and the connecting seat 30 provide accurate installation positions for the connecting shaft 36. By inserting the connecting shaft 36 into the connecting holes 37, stable rotational connection between the rotating seat 31 and the connecting seat 30 can be realized, so that the connecting mechanism 3 can flexibly adjust the angle to adapt to different surgical needs. The precise design of the connecting holes 37 ensures the installation accuracy of the connecting shaft 36, reduces friction and wear during rotation, and improves the service life and reliability of the connecting mechanism 3.

[0040] The fixing holes 34 are opened on one side of the rotating seat 31 and the connecting frame 33, and the two fixing holes 34 are fixedly matched.

[0041] By adopting the above technical scheme, the fixing holes 34 opened on one side of the rotating seat 31 and the connecting frame 33 provide convenience for the fixation of the fixing frame 32 and the connecting frame 33. The fixing frame 32 and the connecting frame 33 can be fixed together by using appropriate fixing pieces through the fixing holes 34, which can ensure the firm and reliable connection between the connecting mechanism 3 and the fixing mechanism 4. This fixing method is simple and easy to operate, can quickly complete the connection, and is relatively convenient when disassembled, which is conducive to the smooth progress of the operation and the disassembly of the device after the operation.

[0042] Working principle: after the adjustment of the adjustment mechanism 2 is completed, the installation of the connecting mechanism 3 is carried out. Align the two clamping pieces 35 on one side of the connecting seat 30 with the clamping groove 25 on the end clamping block 26 of the secondary adjustment rod 24, and push the connecting seat 30 to make the clamping piece 35 clamped into the clamping groove 25, realizing the preliminary connection of the connecting mechanism 3 and the adjustment mechanism 2. Then, the connecting shaft 36 is inserted into the connecting hole 37 opened on both sides of the rotating seat 31 and the connecting seat 30, so that the rotating seat 31 can rotate relative to the connecting seat 30 around the connecting shaft 36, so that the angle of the connecting mechanism 3 can be adjusted flexibly according to the actual installation situation. Then, the fixing frame 32 is placed on the inner side of the connecting frame 33, and the fixing frame 32 and the connecting frame 33 are fixedly connected by rotating the fixing hole 34 opened on one side of the rotating seat 31 and the connecting frame 33, using appropriate fixing pieces such as bolts, etc., to ensure the stability of the overall structure of the connecting mechanism 3. At this time, the connecting mechanism 3 is stably connected to the adjustment mechanism 2, and can be rotated and adjusted by a certain angle through the connecting shaft 36, preparing for the subsequent connection with the fixing mechanism 4.

[0043] Example three: as shown in Figures 7-8 The fixing mechanism 4 includes two fixing rods 40, which are located below the connecting mechanism 3. The two ends of the fixing rod 40 are fixedly provided with sliding rods 41. The outer side of the sliding rod 41 is provided with a positioning block 43. The outer side of the positioning block 43 is provided with a positioning hole 48, which is in sliding fit with the sliding rod 41. The two sides of the positioning block 43 are fixedly provided with limiting blocks 42. The outer side of the positioning block 43 is provided with a positioning frame 44. The two inner walls of the positioning frame 44 are provided with limiting grooves 47, which are in sliding fit with the limiting blocks 42. The upper surface of the positioning frame 44 is fixedly provided with a connecting piece 49, which is fixedly matched with the fixing frame 32. The lower surface of the positioning frame 44 is fixedly provided with a spine positioning screw 45.

[0044] By adopting the above technical scheme, when the connecting mechanism 3 is installed, the fixing mechanism 4 is installed. First, the two fixing rods 40 are placed in the appropriate position, and the sliding rods 41 at both ends of the fixing rods 40 play the role of supporting and sliding guiding. The positioning hole 48 outside the positioning block 43 is sleeved on the sliding rod 41, so that the positioning block 43 can slide on the sliding rod 41, so as to adjust the position of the positioning block 43 according to the position of the spinal trauma. At the same time, the limiting blocks 42 on both sides of the positioning block 43 are inserted into the limiting grooves 47 opened in the inner walls of the positioning frame 44 on both sides, and the limiting blocks 42 slide in the limiting grooves 47, which can prevent the positioning block 43 from deviating during sliding and ensure the accuracy of positioning. When the positioning block 43 slides to the appropriate position, the connecting piece 49 on the upper surface of the positioning frame 44 is fixedly connected with the fixing frame 32 in the connecting mechanism 3, and bolts or other fixing pieces can be used to fix through the corresponding hole positions. Finally, the spinal positioning screw 45 is accurately implanted into the corresponding bone in the patient's spinal trauma site, and the anti-loose engagement grooves 46 opened on the lower inner wall of the positioning frame 44 and the outer side of the positioning block 43 cooperate with each other to increase the friction force and prevent the spinal positioning screw 45 from loosening after implantation, thereby realizing the stable fixation of the spinal trauma site and providing good conditions for the healing of the spine.

[0045] The lower inner wall of the positioning frame 44 and the outer side of the positioning block 43 are both provided with anti-loose engagement grooves 46.

[0046] By adopting the above technical scheme, the anti-loose engagement grooves 46 opened on the lower inner wall of the positioning frame 44 and the outer side of the positioning block 43 increase the friction and occlusion between the positioning frame 44 and the positioning block 43. During the surgical fixation process, when the spinal positioning screw 45 is subjected to external force, the anti-loose engagement grooves 46 can effectively prevent the positioning frame 44 from sliding or loosening relative to the positioning block 43, thereby enhancing the fixation effect of the fixing mechanism 4 on the spinal positioning screw 45 and improving the stability of the entire surgical fixation device, which is helpful for the healing of the spinal trauma.

[0047] Working principle: when the connecting mechanism 3 is installed, the fixing mechanism 4 is installed. First, place two fixing rods 40 in the appropriate position, and the sliding rods 41 at both ends of the fixing rods 40 serve as support and sliding guide. The positioning hole 48 on the outer side of the positioning block 43 is sleeved on the sliding rod 41, so that the positioning block 43 can slide on the sliding rod 41, so as to adjust the position of the positioning block 43 according to the position of the spinal injury. At the same time, the limiting block 42 on both sides of the positioning block 43 is inserted into the limiting groove 47 on the inner wall of the positioning frame 44, and the limiting block 42 slides in the limiting groove 47, which can prevent the positioning block 43 from deviating during sliding and ensure the accuracy of positioning. When the positioning block 43 slides to the appropriate position, the connecting piece 49 on the upper surface of the positioning frame 44 is fixedly connected with the fixing frame 32 in the connecting mechanism 3, and bolts or other fixing pieces can be used to fix through the corresponding hole positions. Finally, the spinal positioning screw 45 is accurately implanted into the corresponding bone of the patient's spinal injury site, and the anti-loose engagement lines 46 on the lower inner wall of the positioning frame 44 and the outer side of the positioning block 43 are matched with each other to increase the friction force and prevent the spinal positioning screw 45 from loosening after implantation, so as to realize the stable fixation of the spinal injury site and provide good conditions for the healing of the spine.
