[0002] Scoliosis is a common bone disease characterized by an abnormal curvature of the spine. Early-onset scoliosis (EOS) is a special type of scoliosis that occurs in children under 10 years old with immature skeletons. If left untreated, this disease can severely impact the patient's growth and development, including hindering bone development, affecting chest and lung function, and even leading to cardiopulmonary problems, seriously threatening the patient's life and health.

[0003] With the change of lifestyle, adolescents' long periods of sitting, poor sitting posture and lack of exercise have led to increasingly serious spinal problems. Existing spinal correction devices usually use the principle of electromagnetic induction to achieve remote control of spinal growth rods through the magnetic field force generated by the rotation of electromagnet 2. However, during the spinal correction process, adolescents need to replace screws with different apertures as they age.

[0044] Example 4, please refer to the attached Figure 1 -Attached Figure 8 By configuring the first displacement sensor 5231, the two second displacement sensors 57, the temperature sensor 58, the pressure sensor 6, the acceleration sensor 7, and the strain gauge sensor 8, the first displacement sensor 5231 and the two second displacement sensors 57 monitor the growth and development of the spine 3, the temperature sensor 58 monitors the patient's internal temperature, the pressure sensor 6 cooperates with the acceleration sensor 7 and the strain gauge sensor 8 to indirectly obtain the corresponding resistance change of the strain gauge when the patient's spine 3 changes, and the pressure sensor 6 and the acceleration sensor 7 monitor the pressure change and acceleration change of the growth rod assembly 5, providing a basis for doctors to formulate more accurate treatment plans, and achieving good treatment effects;

[0045] The present invention also provides a spinal correction system based on electromagnetic control, comprising the following steps:

[0046] S1. Before using the correction device body 1, check that the external remote control and microcontroller 522 are working properly. Insert the nut 42 and screw into the upper and lower ends of the spine 3, respectively. Use the nut 41 to tighten the spine 3 and the screw. Pull the two pull rods 44 to the opposite position. At this time, the pull rods 44 cause the two clamping plates 46 to move away from each other. Place the entire growing rod assembly 5 into the interior of the upper and lower fixing assemblies 4. Under the action of the spring 45, the clamping plates 46 complete the clamping operation on the growing rod assembly 5, and the growing rod assembly 5 is in the initial support state.

[0047] S2. Secondly, after a period of use, the pressure sensor 6, the acceleration sensor 7 and the strain gauge sensor 8 sense the pressure of the spine 3 on the upper rod 51, the lower rod 52 and the adjustment rod, the force changes and the stress and strain of the spine 3. When the first displacement sensor 5231 and the second displacement sensor 57 monitor the force of the growth rod assembly 5 and the growth changes of the spine 3 in real time, the microcontroller 522 sends a command to the external controller 21, the external controller 21 receives and processes it, and the doctor inputs the control command through the user interface 22 of the external remote control to adjust the position of the growth rod assembly 5. When adjusting the length of the growth rod assembly, the doctor randomly selects two methods. The first method is that the microcontroller 522 controls the second motor 542 to drive the rotating shaft 543 and the second magnet 544 to rotate and generate electricity, which supplies power to the first motor 527. The first motor 527 drives the lifting block 529 on the screw 528 to rise and fall according to the doctor's needs. The second method is that the magnet 1 of the external controller 21 rotates and couples with the internal magnet 2 544 to provide input torque. The rotational motion of the input torque is converted into linear motion through the provided screw 528, thereby pulling the growth rod assembly 5 to extend.

[0048] S3. The lifting block 529 and the connecting block 533 are lifted and lowered, driving the fixing sleeve 531 between the lifting block 529 and the connecting block 533 to slide up and down inside the internal limiting grooves 56 of the upper rod body 51 and the lower rod body 52, thereby controlling the lifting and lowering of the two growing rod assemblies 5 and completing the height adjustment of the adjusting rod inside the upper rod body 51 and the lower rod body 52.

[0049] S4. After the adjustment is completed, the doctor observes the numerical information on the user interface 22 and presses the control button 23 on the external controller 21 to stop, thereby sending a command to the microcontroller 522 to stop the power supply to the second motor 542, the rotating shaft 543, and the second magnet 544, and the lifting block 529 and the slider stop lifting and lowering, thus completing the height adjustment of the stop adjustment rod inside the upper rod body 51 and the lower rod body 52.

[0050] S5. Finally, the doctor monitors the information of the position sensor 5281, the first displacement sensor 5231 and the two second displacement sensors 57 in the correction device body 1 in real time, and observes the position and status of the upper rod body 51, the adjustment rod and the lower rod body 52 in the correction device body 1. The microcontroller 522 transmits the information back to the external controller 21. The doctor views the information through the user interface 22 of the external controller 21, and adjusts and confirms the success of the operation as needed. After completing all necessary operations, the doctor can issue an end command through the control button 23, disconnect the connection with the growth rod assembly 5, and turn off the external controller 21.

[0051] Example 5, please refer to the attached Figure 1 -Attached Figure 8 The second motor 542 drives the rotating shaft 543 and the second magnet 544 to rotate, driving the first motor 527 and the screw 528 in the growth rod assembly 5 to rotate, and provides input torque for the height adjustment of the lifting block 529, the fixed slider 530 and the fixed sleeve 531. The rotational motion of the second magnet 544 completes the mechanical transmission and is converted into a linear lifting motion. A third motor is provided inside the in vitro controller 21. The rotation of the third motor drives the rotation of the first magnet. The first magnet rotates and couples with the internal second magnet 544 to provide input torque. The rotational motion of the input torque is converted into a linear motion through the provided screw 528, thereby pulling the growth rod assembly 5 to extend and retract.

[0052] Specifically, the present invention fixes the nut 42 and the screw at the upper and lower ends of the spine 3 respectively, pulls the two pull rods 44 to opposite positions, and places the entire growth rod assembly 5 between the upper and lower fixing assemblies 4. Under the action of the spring 45, the clamping operation of the clamping plate 46 on the growth rod assembly 5 is completed. At the same time, the pull rod 44, under the action of the spring 45, drives the clamping plate 46 to clamp the upper rod body 51 and the lower rod body 52 in the growth rod assembly 5, which can be automatically adjusted to a suitable distance according to the width of the growth rod assembly 5, and has a good correction effect. The set clamping groove 461 has a good clamping effect, which solves the problem that when the existing correction device main body 1 is used, it needs to replace screws of different apertures as the age of the teenager increases.

[0053] Specifically, the doctor monitors the information of the position sensor 5281, the first displacement sensor 5231 and the two second displacement sensors 57 in the correction device body 1 in real time, and observes the position and status of the upper rod body 51, the adjustment rod and the lower rod body 52 in the correction device body 1, which facilitates the doctor's real-time monitoring and adjustment, and can achieve precise and remote control of the upper rod body 51, the lower rod body 52 and the adjustment rod in the growth rod assembly 5, ensuring the safety and success of the surgical process.

[0054] Working principle:

[0055] First, before using the correction device body 1, make sure that the external controller 21 and the microcontroller 522 are in normal working condition. Then, the nut 42 and the screw need to be inserted into the upper and lower ends of the spine 3 to fix them, respectively. Pull the two pull rods 44 to opposite positions, and place the entire growing rod assembly 5 into the interior of the upper and lower fixing assemblies 4. Under the action of the spring 45, the clamping plate 46 completes the clamping operation of the growing rod assembly 5. The pull rod 44, under the action of the spring 45, drives the clamping plate 46 to clamp the upper rod body 51 and the lower rod body 52 in the growing rod assembly 5. The clamping groove 461 provided has a good clamping effect.

[0056] Insert the upper and lower clamping rings 593 into the two clamping grooves 591 to achieve the clamping connection between the outer cylinders of the two sleeve assemblies 59 and the cover body 592, thereby protecting and supporting the two growing rod assemblies 5;

[0057] The doctor monitors the position of the first displacement sensor 5231 and the two second displacement sensors 57 through the information in the user interface 22 of the external controller 21. After sensing the need to adjust the extension of the correction device body 1, the doctor inputs a control instruction through the control button 23 of the external controller 21 to adjust the position extension of the growth rod assembly 5. The input instruction is received and processed by the external controller 21 and transmitted to the microcontroller 522. By setting an anti-slip pad 26 at the bottom of the support column 24 and the base 25, the anti-slip of the external controller 21 is achieved. At this time, the microcontroller 522 controls the two second motors 542 to drive the rotating shaft 543 and the magnet The second magnet 544 rotates to generate electricity, supplying power to the first motor 527. The first motor 527 drives the screw rod 528 to rise, and the height of the lifting block 529 and the connecting block 533 increases as the screw rod 528 rises. At the same time, it drives the fixing sleeve 531 between the lifting block 529 and the connecting block 533 to slide upward inside the internal limiting groove 56 of the upper rod body 51 and the lower rod body 52, controlling the simultaneous rise of the two growing rod assemblies 5. The first magnet of the external controller 21 rotates and couples with the internal second magnet 544 to provide input torque. The rotational motion of the input torque is converted into linear motion by the provided screw rod 528, thereby pulling the growing rod assembly 5 to extend.

[0058] When it is needed to shorten the adjustment rod in the correction device body 1, the doctor controls the input control instruction at the button 23 through the external controller 21, to adjust the position of the growth rod assembly 5 to shorten, the input instruction is received and processed by the controller, and is transmitted to the microcontroller 522, at this time, the microcontroller 522 controls the two second motors 542 to drive the rotating shaft 543 and the magnet two 544 to generate electricity, and the first motor 527 is powered, the first motor 527 drives the lead screw 528 to descend, the height of the lifting block 529 and the connecting block 533 is lowered with the descending of the lead screw 528, and at the same time, the fixed sleeve 531 between the lifting block 529 and the connecting block 533 is limited in the internal limiting groove 56 of the upper rod body 51 and the lower rod body 52 to slide downward, the two growth rod assemblies 5 are controlled to descend to the appropriate height at the same time, the height of the adjustment rod in the upper rod body 51 and the lower rod body 52 is shortened and adjusted, or the doctor rotates the magnet one of the external controller 21 and couples with the internal magnet two 544 to provide an input torque, the rotational motion of the input torque is converted into linear motion through the arranged lead screw 528, so as to pull the growth rod assembly 5 to shorten, the growth and development of the spinal column 3 deformity are improved through the magnetic field control, the growth rod assembly 5 can be controlled through the external controller 21, and damage caused by repeated incision and lengthening in the traditional distraction surgery is avoided.
