[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. A multi-level parallel fine-tuning fixation mechanism is set up. Through the cooperation between the various components inside the multi-level parallel fine-tuning fixation mechanism, the overall adjustment convenience of the spinal support fixation device is optimized. Through the cooperation between the splicing components outside the mounting nail, the inner and outer connecting plates are used to limit the mounting nail at the first level. The inner and outer connecting plates are limited at the second level by the elongated inner limiting plate and the elongated outer adjusting plate. This effectively improves the convenience of fixing and adjusting the mounting nail, ensuring that the spinal support fixation device can be quickly adjusted according to the direction of the patient's spine. Furthermore, the double-layer parallelogram structure formed by the inner and outer connecting plates, the elongated inner limiting plate, and the elongated outer adjusting plate allows the mounting nail to be adjusted at multiple angles while maintaining parallel pairs, effectively improving the overall stability of the mounting nail structure. Simultaneously, indirect limiting and fixation are achieved through symmetrically arranged mounting pins on the rotating adjusting sleeve and rotating adjusting internal thread rod, preventing abnormal swinging of the mounting pins under external force and causing abnormal damage to the patient's spinal bones. The adjustment process of the spinal support and fixation device is optimized using auxiliary accessories on the elongated inner limiting plate and elongated outer adjusting plate, ensuring the structural stability of the spinal support and fixation device after adjustment. Furthermore, the interaction between the pressure sensor and the arc-shaped silicone contact strip enables real-time monitoring of the skin condition at the patient's spine, ensuring that the spinal support and fixation device can provide early warning when subjected to abnormal external force, and can assist medical staff in conducting examinations, effectively expanding the function and scope of application of the spinal support and fixation device.

[0015] 2. An external multi-level binding adjustment mechanism is set up. Through the cooperation between the various components inside the external multi-level binding adjustment mechanism, the binding adjustment process of the spinal support and fixation device is optimized. Through the cooperation between the binding limiting structures on both sides of the spinal support and fixation device, additional binding can be applied to the side of the ribs at the affected area to restrict the patient's lumbar range of motion through the spinal support and fixation device. In this way, the overall protective effect of the spinal support and fixation device is improved by further restricting the patient's range of motion. At the same time, the back isolation airbag and the lumbar isolation airbag cooperate to flexibly limit the spinal support and fixation device, and the tightness of the binding is indirectly monitored by the air pressure sensor, further optimizing the use and adjustment process of the spinal support and fixation device. Meanwhile, the modular design of the various assembly structures connected to the elastic connecting belt and the arc traction belt allows for quick disassembly and reassembly of the upper, lower, and middle elastic clamps and the main body of the mounting nails. This enables the spinal support and fixation device to be quickly adjusted according to the patient's actual needs, improving the overall versatility of the device. Furthermore, the replaceable battery compartment design allows for quick battery changes during use, effectively enhancing the overall ease of use of the spinal support and fixation device.

[0016] In summary, through the cooperation between the internal components of the multi-level parallel fine-tuning fixation mechanism and the external multi-level binding adjustment mechanism, and through the combined structural design of the external connecting component and the side connecting component with the connecting nail, the spinal support and fixation device can be quickly adjusted and combined according to the patient's actual needs during use. This effectively improves the overall practicality, convenience, and ease of use of the spinal support and fixation device. Furthermore, the addition of auxiliary detection sensors allows for auxiliary detection of the patient's and the spinal support and fixation device's operational status, further expanding the device's functionality and thus effectively improving its overall usability.

The side of the elastic connecting vertical strap 320 is fixedly connected to the connecting back strap 218. Through the cooperation between the internal components of the external multi-level binding adjustment mechanism 3, the binding adjustment process of the spinal support and fixation device is optimized. Through the cooperation between the binding limiting structures on both sides of the spinal support and fixation device, additional binding can be applied to the side of the ribs of the affected area to restrict the range of motion of the patient's waist through the spinal support and fixation device. In this way, the overall protective effect of the spinal support and fixation device is improved by further restricting the range of motion of the patient. At the same time, the back isolation airbag 314 and the waist isolation airbag 317 cooperate to flexibly limit the spinal support and fixation device, and the air pressure sensor 315 is used to indirectly monitor the tightness of the binding, further optimizing the use and adjustment process of the spinal support and fixation device. Meanwhile, the modular design of the various assembly structures connected to the elastic connecting band 303 and the arc traction band 309 allows for quick disassembly and reassembly of the upper elastic hoop 305, lower elastic hoop 306, and middle elastic hoop 307 from the main body of the mounting connecting nail 1. This enables the spinal support and fixation device to be quickly adjusted according to the patient's actual needs, improving the overall versatility of the spinal support and fixation device. It also allows for rapid on-site adjustments based on the patient's overall condition during use. Furthermore, the replaceable battery block 319 design allows for quick battery replacement during use, effectively improving the overall ease of use of the spinal support and fixation device.

[0021] The working principle and usage process of this invention: In practical application, when using the spinal support and fixation device to provide auxiliary support for the patient's spine, medical personnel first need to implant the installation connecting nail 1 into the patient's spine and determine the shape of the patient's spine after support. Then, the connecting outer screw 202 is installed to the end of the installation connecting nail 1 through the connecting block 201, and the ends of the inner connecting plate 203 and the outer connecting plate 204 are movably spliced ​​through the connecting collar 205. The locking bolt 216 is adjusted to a loose state to ensure that the inner connecting plate 203 and the outer connecting plate 204 can swing relative to each other. During the swinging process of the inner connecting plate 203 and the outer connecting plate 204, the elongated elliptical limiting inner plate 213 and the elongated elliptical adjusting outer plate 214 swing synchronously. Then, the ends of the inner connecting plate 203 and the outer connecting plate 204 are fitted onto the outer layer of the corresponding connecting outer screw 202, and the deflection angles of the inner connecting plate 203 and the outer connecting plate 204 are passively adjusted according to the direction of the mounting connecting nail 1. Then, the inner connecting plate 203 and the outer connecting plate 204 are pressed and limited by the hexagonal limiting ring 206, and the telescopic direction of the long oval limiting guide groove 215 and the long oval adjusting outer plate 214 is controlled by the long oval limiting guide groove 215 and the locking bolt 216. The guide is used to prevent the elongated inner plate 213 and the elongated outer plate 214 from shifting during the adjustment process. The locking bolts 216 are used to lock and fix the elongated inner plate 213 and the elongated outer plate 214. At the same time, the silicone limiting strip 217 increases the friction between the side of the elongated outer plate 214 and the elongated inner plate 213 to prevent the elongated inner plate 213 and the elongated outer plate 214 from slipping against each other after being subjected to force. When lateral limiting is required between the mounting connecting nails 1, the rectangular connecting block 209 is installed to the end of the connecting external screw 202 through the cooperation between the lateral mounting fine hole 207 and the internal connecting bolt 208. The rotating adjusting sleeve 210 is rotated to extend and retract along the outside of the rotating adjusting internal thread rod 211. The relative extension and retraction between the rotating adjusting sleeve 210 and the rotating adjusting internal thread rod 211 provides auxiliary limiting between the mounting connecting nails 1, preventing the mounting connecting nails 1 from deflecting to both sides of the spine after being subjected to force, and further improving the overall structural strength of the spinal support and fixation device. When it is necessary to bind and protect the outside of the spinal support and fixation device, the connecting rectangular block 302 is installed on one side of the rectangular connecting block 209 through the side connecting hole 301, and the upper elastic hoop 305, lower elastic hoop 306 and middle elastic hoop 307 are respectively installed to the ends of the corresponding rectangular connecting blocks 209 through the elastic connecting strap 303 and the snap-fit ​​rectangular block 304, so as to realize the elastic connection of the outer layer of the upper elastic hoop 305, lower elastic hoop 306 and middle elastic hoop 307. Then, the arc traction strap 309 is connected to the inner side of the corresponding upper elastic hoop 305, lower elastic hoop 306 and middle elastic hoop 307 through the cooperation between the movable buckle 308 and the fixed buckle 310, thereby realizing the assembly of the spinal support and fixation device. Then, the upper elastic band 305, the lower elastic band 306, and the middle elastic band 307 are bound together on the front by the front binding strap 311, and the ends of the front binding strap 311 are limited by the cooperation between the needle-side connecting hook and loop fastener 312 and the rough-side connecting hook and loop fastener 313, so as to ensure that the upper elastic band 305, the lower elastic band 306, and the middle elastic band 307 can be tightly bound to the outside of the patient's torso.

Then, the lumbar isolation airbag 317 provides flexible isolation to the inside of the middle elastic band 307 to ensure that the middle elastic band 307 fits more closely with the patient's waist. After the upper elastic band 305, lower elastic band 306 and middle elastic band 307 are bundled into the appropriate position, the pressure inside the back isolation airbag 314 is adjusted by the bottom inflation valve 316, and the pressure sensor 315 is used to detect the pressure of the inner ring of the upper elastic band 305, lower elastic band 306 and middle elastic band 307 in real time to ensure that the pressure between the spinal support and fixation device and the patient can be maintained within a suitable range, which further improves the comfort of using the spinal support and fixation device. At the same time, the battery block 319 is attached to the side of the lower elastic band 306 by the mounting block 318, so as to continuously power the various sensors used inside the spinal support and fixation device by the battery block 319. Simultaneously, the elastic connecting strip 219 is installed on the back of the rotating adjustment sleeve 210 through the magnetic connecting strip 321 and the elastic connecting vertical strip 320. The pressure sensor 221 and the elastic telescopic rubber strip 222 are installed on the side of the elastic connecting strip 219 through the mounting narrow plate 220. The arc-shaped silicone contact strip 223 is in contact with the skin in the middle of the patient's spine. The pressure sensor 221 detects the pressure on the patient's back spine in real time to ensure that any abnormal compression or swelling in the patient's spine can be detected in time. This further expands the function of the spinal support and fixation device and improves the smoothness of use of the spinal support and fixation device.
