Detailed Implementation

[0025] 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.

[0026] like Figures 1 to 6 As shown, the present invention provides a spinal surgery positioning and guidance system, including a support frame 1, a connecting component 2 disposed in the inner cavity of the support frame 1, an installation component 3 fixedly installed at the end of the support frame 1, and a fixing component 4 fixedly installed at the bottom of the support frame 1. The connecting component 2 includes a drive unit 21, limiting units 22 fixedly disposed on both sides of the drive unit 21, a telescopic rod 23 fixedly installed between the limiting units 22, a connecting unit 24 fixedly installed at the bottom of the telescopic rod 23, the limiting unit 22 includes a fixing block 222, a limiting member 221 movably connected to one side of the fixing block 222, limiting blocks 223 disposed on both sides of the fixing block 222, and a spring 224 fixedly installed between the limiting block 223 and the fixing block 222.

[0027] The above solution involves the cooperation of the limiting unit 22 and the support frame 1. After the patient's treatment is completed, the device needs to be cleaned to prevent infection when used on the next patient. Pulling the limiting block 223, which has a semi-circular handle at the top, makes it easier to move. This allows the limiting block 223 to engage with the limiting member 221. Then, the limiting member 221 is moved, and both limiting members 221 move to the sides. The limiting member 221 then removes the telescopic rod 23 and the connecting unit 24, making it easier to clean the limiting member 221 and the connecting unit 24. This avoids spending a lot of time cleaning the device and allows for better storage after disassembly and cleaning, preventing the device from taking up too much space and wasting space. Furthermore, the telescopic rod 23 has telescopic sides, which allows for better disassembly of the telescopic rod 23 and the connecting unit 24 when the limiting member 221 is released from engagement with the fixing block 222.

[0028] like Figure 2 , Figure 3 As shown, the drive unit 21 includes a toothed plate 211, with a first gear 212 meshing with the bottom of the toothed plate 211. A rotating shaft 213 is fixedly installed in the middle of the toothed plate 211, and a drive motor 214 is fixedly installed at one end of the rotating shaft 213. A support plate 215 is movably connected to the outer wall of the rotating shaft 213, and the support plate 215 is fixedly connected to the bottom of the inner cavity of the support frame 1. The connecting unit 24 includes a connecting rod 241, with a threaded rod 242 threadedly connected to the outer wall of the connecting rod 241. A back plate 243 is fixedly installed at the bottom of the threaded rod 242. The mounting assembly 3 includes a mounting block 31, with a mounting component 32 movably connected to the inner cavity of the mounting block 31. The mounting block 31 is fixedly connected to the support frame 1, and a through hole is provided at the end of the mounting component 32.

[0029] Using the above scheme: Through the cooperation of the drive unit 21 and the connecting unit 24, the threaded rod 242 is rotated according to the patient's body shape. The threaded rod 242 drives the backplate 243 to move, thereby removing the backplate 243 and the threaded rod 242 for replacement. This allows for the replacement of a backplate 243 that matches the patient's body shape. Furthermore, the backplate 243 can be disassembled after spinal surgery, making cleaning easier. After replacement, the drive motor 214 is started. The drive motor 214 rotates, driving the rotating shaft 213 and the first gear 212 to rotate. The rotation drives the toothed plate 211 to move, which in turn moves the telescopic rod 23 and the connecting unit 24. This movement allows for adjustments to the position of the telescopic rod 23 and the connecting unit 24 based on the patient's body, thus providing better guidance for spinal surgery. After the device is fixed, the spinal surgery guidance instrument is placed into the through hole of the mounting piece 32, facilitating stability during surgery and preventing arm pain from prolonged instrument handling. The mounting piece 32 can rotate 360 ​​degrees, further enhancing patient treatment.

[0030] like Figure 2 , Figure 6 As shown, the fixing component 4 includes a fixing member 41, and a fixing unit 42 is provided in the inner cavity of the fixing member 41. The fixing member 41 is fixedly connected to the bottom surface of the support frame 1. The fixing member 41 includes a servo motor 421. A second gear 422 is fixedly installed at the output end of the servo motor 421. A toothed plate 423 is meshed on both sides of the second gear 422. A fixing rod 424 is fixedly installed at the bottom of the toothed plate 423. A through groove is opened on the bottom surface of the fixing member 41, and the fixing rod 424 is movably connected to the through groove. The toothed plate 423 is movably connected to the fixing member 41.

[0031] The above scheme is adopted as follows: Through the cooperation of the fixation component 41 and the fixation unit 42, when the patient is receiving treatment and lying down, the servo motor 421 is started. The rotation of the servo motor 421 drives the second gear 422 to rotate. The rotation of the second gear 422 drives the two toothed plates 423 and the fixing rod 424. The lower ends of the two fixing rods 424 are both set as arcs, and the inner wall of the arc is provided with a sponge block. The design of the sponge block protects the patient's head when fixing it. After moving to a certain position, the patient's head is fixed. The fixation of the head can ensure that the patient maintains a stable position throughout the operation and avoids affecting the accurate positioning of the spine due to head displacement. The through groove design of the fixation component 41 allows the fixing rod 424 to be limited when moving, making the fixing rod 424 more stable when moving. The toothed plate 423 is movably connected to the fixation component 41, so that the fixation component 41 limits the toothed plate 423 when moving, making the toothed plate 423 more stable when moving.

[0032] like Figures 3 to 6 As shown, sliders are provided on the bottom and top surfaces of the inner cavity of the support frame 1, and grooves are provided on the top and bottom surfaces of the toothed plate 211. The support frame 1 and the toothed plate 211 are movably connected. A handle is provided at the end of the toothed plate 211. Grooves are provided on the top and bottom surfaces of the limiting member 221. The limiting block 223 is engaged with the groove. The fixing block 222 is fixedly connected to the toothed plate 211. The limiting member 221 is set in an "L" shape, and a fixing clip is provided at the end of the limiting member 221. A rubber plate is provided at the bottom of the back plate 243, and the back plate 243 is set in an arc shape.

[0033] The above scheme is adopted as follows: through the cooperation of the support frame 1 and the toothed plate 211, and the cooperation of the slider of the support frame 1 and the groove of the toothed plate 211, the slider limits the toothed plate 211 when the first gear 212 drives the toothed plate 211 to move, making the toothed plate 211 more stable during movement. Through the cooperation of the groove of the limiting member 221 and the limiting block 223, the limiting block 223 is engaged with the groove of the limiting member 221, so that when the device is fixed, the limiting member 221 is fixed by the engagement of the limiting block 223 and the groove. The bottom fixing clip of the limiting member 221 is fixed to the outside, thereby fixing the spinal surgery positioning and guiding device, which can better treat the patient. Through the setting of the rubber plate at the bottom of the back plate 243, the patient's back will not feel uncomfortable when the back plate 243 contacts the patient's back, thus making it easier to accept treatment. The arc-shaped design of the back plate 243 allows it to fit better with the patient's back.
