The spinal surgery fixator provided with a positioning guide structure, during use, the main board dissipates heat through the ventilation port, so that the patient can use the device better; Furthermore, during use, when the wearer feels stuffy on the back, the motor can be started, and the motor drives the threaded rod to rotate, and then the slide plate descends in the vertical direction under the action of the threaded rod and the limit rod. When the slide plate descends to push the auxiliary rod, the auxiliary rod drives the baffle to move to the side of the main board. At this time, the exposed area of ​​the ventilation port is increased, which can better ventilate and optimize comfort. Furthermore, when the baffle moves toward the side of the main board, the first spring will be squeezed, and when the motor rotates and the slide plate rises, the baffle will move back under the action of the first spring and the limit plate, and the exposed area of ​​the vent will be reduced, that is, the wearer can flexibly adjust the size of the exposed area of ​​the vent, which is highly flexible. (3) The spinal surgery fixator provided with a positioning guide structure, during the process of the slide plate descending, the slide plate will drive the push block to move synchronously, and then the push block will intermittently contact the force-bearing block. When the push block pushes the force-bearing block, the force-bearing block drives the movable plate to move in the direction of squeezing the second spring. When the push block continues to move until it does not contact the force-bearing block, the movable plate moves back under the action of the second spring, and the above process is repeated. The movable plate drives the massage block to perform reciprocating linear motion in the horizontal direction. At this time, the massage block will press the wearer's back again and again, making the wearer's back muscles more relaxed, further improving comfort and facilitating the wearer's recovery. In this process, the cross bar and the partition limit the moving distance and movement direction of the movable plate to ensure stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: By setting the extrusion rod 5, the stress state of the slide rod 4 can be changed, and then the distance between the main board 1 and the auxiliary board 2 and the side board 3 can be changed, that is, the application range of the device as a whole is expanded, such as Figure 1-Figure 3 As shown: A spinal surgery fixator with a positioning guide structure comprises a main plate 1 and a sub-plate 2, wherein a slide bar 4 is slidably arranged on both the left and right sides of the main plate 1 and the left and right sides of the sub-plate 2, and a side plate 3 is fixedly connected to the other side of the slide bar 4, and adjacent side plates 3 are movably connected by external binding straps; A motor 6 is fixedly connected to the surface of the main board 1, and a limit rod 7 is fixedly connected to the outer wall of the main board 1, and a vent 9 is opened on the surface of the main board 1, and an adjustment component is arranged on the surface of the main board 1, and the adjustment component includes a baffle 11 slidably arranged on the surface of the main board 1. When the adjustment component is working, the size of the vent 9 is changed by sliding the baffle 11; A massage component is arranged on the surface of the main board 1, and the massage component includes a movable plate 17 movably arranged on the surface of the main board 1, and a massage block 18 is fixedly connected to the surface of the movable plate 17. When the massage component is working, the massage block 18 presses the back of the wearer again and again. A threaded rod 10 is fixedly connected to the output end of the motor 6, and a slide plate 8 is threadedly connected to the surface of the threaded rod 10.

[0020] The slide bars 4 are evenly spaced on the side of the side plate 3, and the inside of the main plate 1 and the inside of the sub-plate 2 are both threadedly connected with extrusion rods 5, which are symmetrically distributed about the center of the side plate 3, and the surface of the side plate 3 is evenly spaced with through holes 23.

[0021] When it is necessary to adjust the size of the device, the extrusion rod 5 can be rotated to move the extrusion rod 5 to the outside of the main board 1 and the sub-board 2. At this time, the slide bar 4 will not be supported by the extrusion rod 5, and the side panel 3 can be pulled to adjust the position of the side panel 3. After the adjustment, the extrusion rod 5 can be rotated in the opposite direction to make the extrusion rod 5 support the slide bar 4 again. That is, through the above operation, the distance from the main board 1 to the side panel 3 can be quickly adjusted (the distance from the sub-board 2 to the side panel 3 can also be quickly adjusted), that is, the operator can quickly adjust the overall size of the device, thereby expanding the scope of use and improving flexibility.

[0022] Embodiment 2: Different from Embodiment 1, the size of the vent 9 can be quickly adjusted by setting an adjustment component, so that the wearer can dissipate heat according to actual conditions, thereby improving comfort. Figure 4-Figure 7 As shown: The adjustment component also includes a limit plate 13 fixedly connected to the surface of the main board 1, and the end of the limit plate 13 is slidably set inside the baffle 11, and the limit plate 13 is symmetrically distributed about the center of the baffle 11, and the air vents 9 are evenly spaced on the surface of the main board 1.

[0023] The limit plate 13 is an inverted "L" structure when viewed from above. The inner surface of the baffle plate 11 is fixedly connected to an auxiliary rod 12, and the end of the auxiliary rod 12 is inclined. The surface of the baffle plate 11 is fixedly connected to a first spring 14 that plays an elastic reset role, and the other side of the first spring 14 is fixedly connected to the inner wall of the limit plate 13.

[0024] During use, the main board 1 dissipates heat through the air vents 9, so that the patient can use the device better. During use, when the wearer feels stuffy on his back, the motor 6 can be started. At this time, the motor 6 drives the threaded rod 10 to rotate, and then the slide plate 8 descends in the vertical direction under the action of the threaded rod 10 and the limit rod 7. When the slide plate 8 descends to push the auxiliary rod 12, the auxiliary rod 12 drives the baffle 11 to move to the side position of the main board 1. At this time, the exposed area of ​​the air vent 9 is increased, which can better ventilate and optimize comfort. When the baffle 11 moves to the side position of the main board 1, the first spring 14 will be squeezed. When the motor 6 rotates and the slide plate 8 rises, the baffle 11 will move back under the action of the first spring 14 and the limit plate 13. At this time, the exposed area of ​​the air vent 9 is reduced, that is, the wearer can flexibly adjust the size of the exposed area of ​​the air vent 9, which is highly flexible.

[0025] Embodiment 3: Different from Embodiment 2, a massage assembly is further provided, and the movable plate 17 drives the massage block 18 to move in the horizontal direction, so that the massage block 18 presses the back of the wearer again and again, so that the back muscles of the wearer are more relaxed, further improving the comfort and facilitating the recovery of the wearer. Figure 8-Figure 10 As shown; The massage component also includes a cross bar 15 fixedly connected to the surface of the main board 1, and the cross bar 15 is slidably connected to the movable plate 17, and the end of the cross bar 15 is fixedly connected to the partition 16, the ends of the two sides of the slide plate 8 are both concave, and a push block 21 is fixedly connected to the inner wall of the slide plate 8, and a force block 22 corresponding to the push block 21 is fixedly connected to the inner wall of the movable plate 17, and the force block 22 and the push block 21 are both hemispherical structures, and the force blocks 22 are evenly spaced on the inner wall of the movable plate 17.

[0026] A second spring 20 that plays an elastic reset role is fixedly connected to the outer wall of the movable plate 17, and the other side of the second spring 20 is fixedly connected to the inner wall of the partition 16. The massage blocks 18 are evenly distributed on the surface of the movable plate 17, and the massage blocks 18 pass through the interior of the main board 1, and the massage blocks 18 are slidably connected to the main board 1.

[0027] During the descent of the slide plate 8, the slide plate 8 will drive the push block 21 to move synchronously, and then the push block 21 will intermittently contact the force block 22. When the push block 21 pushes the force block 22, the force block 22 drives the movable plate 17 to move away from the main plate 1, that is, the movable plate 17 moves in the direction of squeezing the second spring 20. When the push block 21 continues to move until it does not contact the force block 22, the movable plate 17 moves back under the action of the second spring 20, and the force blocks 22 are evenly spaced on the inner wall of the movable plate 17, and the above process will be repeated. When the above process is repeated, the movable plate 17 drives the massage block 18 to make reciprocating linear motion in the horizontal direction. At this time, the massage block 18 will press the wearer's back again and again, so that the wearer's back muscles are more relaxed, further improving the comfort and facilitating the wearer's recovery. In this process, the cross bar 15 limits the movement direction of the movable plate 17, so that the movable plate 17 can only move in the horizontal direction. The partition 16 limits the moving distance of the movable plate 17, and the movable plate 17 will not fall, thereby ensuring stability.

[0028] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
