Description

Technical Field

[0001] This invention relates to the technical field of medical devices, and in particular to a spinal fixation plate structure. Background Technology

[0002] Spinal fixation plates are used to initially stabilize a patient's spine when it is dislocated or injured, and then transport the patient to a spinal surgeon for further treatment.

[0003] A search revealed that patent number CN221712395U discloses a fixation plate for spinal surgery reduction. Through the cooperation of fixation and limiting components, it solves the technical problems of most current reduction fixation plates having a simple structure and using a strap-type fixation method, which is insufficient in terms of stability and patient comfort after reduction. The plate lifts the patient to the front of the top and then slowly pulls the patient back, performing initial reduction of the spine. Rotating the first adjustment handle uses a threaded rotation to move two sets of first sponge blocks, providing stable limiting and fixing support on both sides of the patient's spine. This avoids secondary injury caused by spinal displacement during transport. Compared to strap-type fixation, it offers greater comfort and has good practicality.

[0004] However, in actual use, the patient needs to be lifted to the front of the top of the fixation plate and then slowly pulled back to put the fixation and limiting components on the fixation plate onto the patient's spine. This operation is time-consuming and laborious. Moreover, because the patient's spine is injured and movement is inconvenient, secondary injury is likely to occur during the operation. Therefore, there are areas for improvement. Summary of the Invention

[0029] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.

[0030] This invention discloses a spinal fixation plate structure. (Refer to...) Figures 1-8A spinal fixation plate structure includes a fixation plate body 1 and side guard plates 2. Side guard plates 2 are set on both the left and right sides of the fixation plate body 1 through a flipping structure. A headrest 34 is set on the fixation plate body 1 near the front through a lifting structure. A first driving structure is located inside the fixation plate body 1. A first sponge pad 3 is set on the side guard plate 2. An upper guard plate 19 is set on the side guard plate 2 through a folding structure. An insertion structure is set between the two upper guard plates 19. A second sponge pad 20 is set on the upper guard plate 19.

[0031] The flipping structure includes a flipping opening 4 in the middle of the left and right sides of the fixed plate body 1. A first adjustment structure is set in the flipping opening 4. A moving block 5 is slidably set in the flipping opening 4. A first groove 7 is opened on the moving block 5. A rotating rod 6 is rotatably passed through the moving block 5. Two flipping handles 8 are fixedly sleeved on the rotating rod 6. One end of the flipping handle 8 is fixedly connected to the side guard plate 2.

[0032] The first driving structure includes an inner groove 9 formed in the main body of the fixed plate 1. The inner groove 9 is connected to the flipping opening 4. A first threaded rod 11 is rotatably inserted into the middle of the rear side of the main body of the fixed plate 1. A first rotating wheel 10 is installed at one end of the first threaded rod 11. The other end of the first threaded rod 11 is rotatably connected to the groove wall of the inner groove 9. A movable plate 12 is slidably arranged in the inner groove 9. The two ends of the movable plate 12 are attached to the groove wall of the inner groove 9. A threaded groove for the first threaded rod 11 to pass through is opened in the middle of the movable plate 12. Two sliding grooves are opened on one side of the movable plate 12. A sliding strip 13 is slidably arranged in each sliding groove. One end of the sliding strip 13 is movably inserted into the driving rod 14. One end of the driving rod 14 is connected to the rotating rod 6. A spiral groove 16 is opened on the driving rod 14. One end of the sliding strip 13 is fixedly inserted into the insert rod 15. One end of the insert rod 15 is movably inserted into the spiral groove 16.

[0033] The first adjustment structure includes a bidirectional screw 18 that rotates through the main body 1 of the fixing plate. Fixing blocks 17 are connected to the middle of both sides of the main body 1 of the fixing plate. The two sections of the bidirectional screw 18 have opposite thread directions. The bidirectional screw 18 passes through a threaded groove on the movable block 5. Second rotating wheels 43 are provided at both ends of the bidirectional screw 18 that rotate through the fixing blocks 17. When fixing the patient's spine, firstly, the main body 1 of the fixing plate is placed on the patient's back spine. Then, the first rotating wheel 10 is used to rotate the first threaded rod 11, and the movable plate 12 rotates... The first threaded rod 11 moves, causing the insertion rod 15 at one end of the sliding bar 13 to slide in the spiral groove 16 of the driving rod 14. The insertion rod 15 squeezes the groove wall of the spiral groove 16, causing the driving rod 14 and the rotating rod 6 to rotate as a whole, thereby simultaneously rotating the two side guard plates 2 on the fixed plate body 1. Then, the second rotating wheel 43 rotates the bidirectional screw 18, and the two moving blocks 5 drive the two rotated side guard plates 2 to move synchronously towards the middle. The first sponge pad 3 on the side guard plate 2 is pressed against the two groups of the patient's spine to perform limiting and fixing support work.

[0034] See Figure 3 and Figure 4 The plug-in structure is set at one end of the plug-in block 21 of one upper guard plate 19, and the other upper guard plate 19 has a plug-in groove at one end.

[0035] The folding structure includes a fixing rod 22 set on the side guard plate 2, a hollow ball 23 installed at one end of the fixing rod 22, a spherical block 24 movably arranged inside the hollow ball 23, a second flip groove 27 opened on the hollow ball 23, a first flip groove 26 opened on the hollow ball 23 communicating with the second flip groove 27, a flip plate 28 connected to the spherical block 24, the flip plate 28 movably passing through the second flip groove 27, one end of the flip plate 28 connected to the upper guard plate 19, a limiting groove 25 opened on the side guard plate 2 corresponding to the position of the first flip groove 26, and a second adjustment structure set on the side guard plate 2;

[0036] The second adjustment structure includes a second groove 29 formed on the side guard plate 2, an adjustment plate 30 disposed in the second groove 29, the two ends of the adjustment plate 30 being attached to the groove wall of the second groove 29, one end of a fixing rod 22 being fixedly connected to the adjustment plate 30, a second threaded rod 31 being rotatably inserted into the second groove 29, the second threaded rod 31 passing through the threaded groove formed on the adjustment plate 30, and a rotating block 32 being disposed at the top end of the second threaded rod 31. The rotation of the spherical block 24 within the hollow sphere 23 drives the flipping plate 28 to rotate from the second flipping groove 27 to the first flipping groove. In groove 26, the flip plate 28 passes through the limiting groove 25 of the side guard plate 2, so that the upper guard plate 19 can be rotated from the side guard plate 2 and pressed against the patient's chest. When the two side guard plates 2 move towards each other, they drive the insertion block 21 to insert into the insertion groove, and insert the two upper guard plates 19 together. Then, according to the actual needs, the second threaded rod 31 is rotated by the rotating block 32, and the height of the upper guard plate 19 after insertion is flexibly adjusted by the movement of the adjusting plate 30 in the second groove 29, so as to ensure the stability of the support for the patient's spine.

[0037] See Figure 1 , Figure 5 and Figure 6 The lifting structure includes a first through groove 33 opened on the fixed plate body 1. T-shaped rods 35 are connected to the four corners of the fixed plate body 1 near the first through groove 33. A lifting plate 36 is movably sleeved on the T-shaped rods 35. An installation plate 37 is set on the lifting plate 36. A headrest 34 is set on the installation plate 37. A second driving structure is set between the lifting plate 36 and the moving plate 12.

[0038] The second driving structure includes a second through groove 38 located below the fixed plate body 1. The second through groove 38 is connected to the inner groove 9. An L-shaped strip 39 moves through the second through groove 38. The top end of the L-shaped strip 39 is connected to the movable plate 12. A driving frame 40 is provided at the other end of the L-shaped strip 39. A driving plate 41 is tightly attached to one side of the lifting plate 36. A driving groove 42 is provided on the driving plate 41. The driving frame 40 moves through the driving groove 42. During the movement of the movable plate 12, the driving frame 40 slides in the driving groove 42 of the lifting plate 36. By using the compression of the groove wall of the driving groove 42 by the driving frame 40, the headrest 34 is automatically pushed out from the first through groove 33 to support the patient's head. The structure is simple and the function is practical.

[0039] The implementation principle of a spinal fixation plate structure according to an embodiment of the present invention is as follows: First, the fixation plate body 1 is fitted onto the spine of the patient's back. Then, the first rotating wheel 10 rotates the first threaded rod 11, and the moving plate 12 moves on the rotating first threaded rod 11, causing the sliding bar 13 to slide one end of the insertion rod 15 in the spiral groove 16 of the driving rod 14. The insertion rod 15 squeezes the groove wall of the spiral groove 16, causing the driving rod 14 and the rotating rod 6 to rotate as a whole, thereby simultaneously rotating the two side guard plates 2 on the fixation plate body 1. At the same time, the movement of the moving plate 12 causes the driving frame 40 to slide in the driving groove 42 of the lifting plate 36. The driving frame 40 squeezes the groove wall of the driving groove 42, automatically pushing out the headrest 34 from the first through groove 33 to support the patient's head. Then, the rotation of the spherical block 24 in the hollow ball 23 causes the flipping plate 28 to rotate from the second flipping plate. The groove 27 rotates into the first flip groove 26, and the flip plate 28 passes through the limiting groove 25 of the side guard plate 2. In this way, the upper guard plate 19, which rotates from the side guard plate 2, is pressed against the patient's chest. Then, the second rotating wheel 43 rotates the bidirectional screw 18, and the two moving blocks 5 drive the two rotating side guard plates 2 to move synchronously towards the middle. The first sponge pad 3 on the side guard plate 2 is pressed against the two sets of the patient's spine for limiting and fixing support. During the movement of the side guard plate 2, the insertion block 21 is driven to insert into the insertion groove to connect the two upper guard plates 19. According to the actual needs, the second threaded rod 31 is rotated by the rotating block 32, and the height of the upper guard plate 19 after insertion is flexibly adjusted by the movement of the adjusting plate 30 in the second groove 29 to ensure the stability of the support for the patient's spine. In this way, the limiting and fixing support for the patient's spine can be achieved.

[0040] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
