[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] See Figures 1-12 As shown, the present invention provides an intelligent seated lumbar spine rotation reduction device, including a frame 1, a seat area on the frame 1, a seat cushion 3 in the seat area, and a backrest 2 on one side of the seat area to drive the patient's lumbar spine to complete the corresponding reduction action in order to meet the operational requirements of lumbar spine reduction. To achieve multi-dimensional resetting motion of the backrest 2, the frame 1 is equipped with three types of drive components: a forward and backward swing component 4 for driving the backrest 2 to swing back and forth, a left and right rotation component 5 for driving the backrest 2 to rotate left and right, and an axial traction component 6 for driving the backrest 2 to pull upward. It should be noted that the forward and backward swinging component 4, the left and right rotation component 5, and the axial traction component 6 are all integrated on the frame 1 with the backing plate 2 as the actuating end. The three components achieve non-interference in movement through structural layout optimization, and can work together to complete the lumbar spine repositioning action.

[0023] See instruction manual attached Figure 5 , Figure 7 , Figure 8 and Figure 10 As shown, the backing plate 2 is designed as a box-shaped structure with a hollow interior and an open bottom, so as to form a sliding fit with the axial traction component 6. The axial traction component 6 includes a support plate 603, and the backing plate 2 is slidably sleeved on the outside of the support plate 603. The support plate 603 is fixedly mounted on the lifting module pad 502 of the left and right rotating component 5. In order to achieve stable lifting of the backing plate 2, a screw 602 is rotatably provided on the support plate 603. The upper end of the screw 602 is rotatably mounted on the support plate 603 through a screw seat 605, and the lower end is driven to rotate by the axial traction servo motor 601. A lifting nut seat 608 is threadedly connected to the screw 602. The lifting nut seat 608 is fixedly connected to the inner side of the backing plate 2, and the screw drive is converted into linear motion of the backing plate 2. To improve lifting stability, linear slide rails 604 are symmetrically distributed on both sides of the screw 602 with the screw as the center. The linear slide rails 604 are fixed on the support plate 603, and linear sliders 606 are slidably mounted on them. The linear sliders 606 are fixed on the inner side wall of the backing plate 2 through the slider pad 607, forming a double guide support with the screw drive.

[0024] See instruction manual attached Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7, Figure 9 and Figure 10 As shown, the left and right rotation component 5 includes a hollow rotating platform 501. A lifting module pad 502 is rotatably mounted on the upper side of the hollow rotating platform 501. To record the number of left and right rotations, a photoelectric rotary encoder 8 is mounted on the hollow rotating platform 501. A blocking rod 7 that cooperates with the encoder is mounted on the lifting module pad 502. The hollow rotating platform 501 also has a left and right rotation servo motor 503 for driving the rotation of the lifting module pad 502. A rotating sleeve 504 is mounted on the lower side of the lifting module pad 502. An axial traction servo motor 601 is fixed to the lower end of the rotating sleeve 504. The lower end of the screw 602 passes through the rotating sleeve 504 and connects to the output shaft end of the servo motor 601 to ensure smooth power transmission.

[0025] The front-to-back swing assembly 4 includes a front-to-back swing shaft 405, both ends of which are rotatably mounted in the frame 1 via bearing seats 406. The front-to-back swing shaft 405 is driven to rotate by a swing drive structure. The hollow rotating platform 501 is fixed to the front-to-back swing shaft 405 via a mounting base 407. To avoid space constraints for the screw 602, a through hole 408 is provided on the front-to-back swing shaft 405, and a waist hole 505 is provided on the rotating sleeve 504 for the front-to-back swing shaft 405 to pass through. The swing drive structure includes a front-to-back swing servo motor 401, which is fixed in the frame 1 via a motor seat 409. A first synchronous pulley 402 is provided at the output shaft end, and a second synchronous pulley 404 is provided at one end of the front-to-back swing shaft 405. A synchronous belt 403 meshes between the first synchronous pulley 402 and the second synchronous pulley 404, achieving smooth swing drive through belt transmission.

[0026] To ensure the safety of the equipment after shutdown, the forward and backward swing servo motor 401, the left and right rotation servo motor 503 and the axial traction servo motor 601 are all equipped with brakes, which can keep the backing plate 2 fixed in its current position when the power is off.

[0027] See instruction manual attached Figure 1 and Figure 2 As shown, the frame 1 is provided with a front and rear swing opening slot 106 for the back plate 2 to swing back and forth. To prevent dust from entering the equipment, a bellows cover 104 is provided at the front and rear swing opening slot 106.

[0028] The frame 1 has openings on both sides and side sealing plates 101 at the openings. Foot pedals 105 are provided on the side sealing plates 101 to facilitate patient fixation. A lumbar traction belt 11 is provided on the backrest 2 to firmly fix the patient's body to the backrest 2.

[0029] An electrical box 9 is provided on one side of the frame 1 to integrate the electrical control components of the equipment. The electrical box 9 is equipped with a touch screen 10 as a human-machine interface to facilitate operators in setting parameters and monitoring the operating status.

[0030] The hardware block diagram of the control system is as follows Figure 11 As shown, to improve the reliability and cost-effectiveness of the control system, a programmable logic controller (PLC) is used as the control core. To ensure patient safety, limit switches are installed at the limit positions of the backrest 2's forward and backward rocking, left and right rotation, and axial traction. Each servo motor automatically stops when it reaches its limit position. A force sensor is used to monitor the axial traction force in real time. The collected force sensor signal is an mV signal, which is converted into a digital signal after signal processing by the force transmitter. This signal is then transmitted to the CPU through the PLC's built-in 485 communication port, and further processed to convert it into the actual traction force value. A manual / automatic switch is used to switch between manual and automatic working modes. An emergency stop button is used for emergency shutdown. A start button is used for automatic start-up in automatic mode, and a stop button is used for automatic stop-up in automatic mode. The human-machine interface is mainly used for parameter setting, information display, and human-machine interaction. To ensure the control accuracy of the backrest's forward and backward rocking, left and right rotation, and axial traction, servo motors are used to control these three directions. The servo motors use built-in encoders, directly integrated into the rear end cover of the motor, which can monitor the rotation angle of the motor shaft in real time. The built-in encoder is an absolute rotary encoder, a sensor that directly outputs position information through unique encoding. Its core principle is to generate binary or Gray code sequences using lines on a photoelectric or magnetic encoder disk. Each position corresponds to a unique encoded value, and the position information is retained even after power failure, eliminating the need to recalibrate the reference point. The PLC can directly read the servo motor rotation angle value acquired by the rotary encoder via an RS485 communication interface. When situations such as servo motor overload, completion of rotation reset, or expiration of traction treatment time occur, the audible and visual alarm will be automatically triggered, and the corresponding text reminder information will be automatically displayed on the human-machine interface.

[0031] Working principle of this invention: In use, the seating area set on the frame 1 is for the patient to sit in. The patient places both feet on the foot pedals 105 on the side sealing plate 101 and fixes the body to the backrest 2 by the lumbar traction belt 11 on the backrest 2. With the help of the front and back swing assembly 4, left and right rotation assembly 5 and axial traction assembly 6 integrated on the frame 1, the lumbar spine reduction action is completed with the backrest 2 as the execution end, and the movement of the three components does not interfere with each other.

[0032] In terms of the front and back swing function, the front and back swing servo motor 401 is fixed in the frame 1 by the motor base 409. The first synchronous pulley 402 at the output shaft end drives the second synchronous pulley 404 at one end of the front and back swing shaft 405 to rotate through the synchronous belt 403. The front and back swing shaft 405 is rotatably installed in the frame 1 through the bearing seat 406. The hollow rotating platform 501 is fixed on the front and back swing shaft 405 through the mounting seat 407, thereby driving the back plate 2 to swing back and forth around the front and back swing shaft 405. The front and back swing opening slot 106 on the frame 1 provides space for swinging, and the bellows cover 104 plays a role in dust protection.

[0033] The left and right rotation is driven by the left and right rotation component 5. The left and right rotation servo motor 503 drives the hollow rotation platform 501 to reciprocate horizontally, causing the upper lifting module pad 502 to rotate. The support plate 603 is fixed on the lifting module pad 502, thereby driving the back plate 2 to complete the left and right horizontal rotation. The photoelectric rotary encoder 8 on the hollow rotation platform 501 cooperates with the blocking rod 7 on the lifting module pad 502 to realize the detection of the number of left and right rotations.

[0034] The axial traction function is achieved through the axial traction assembly 6. The axial traction servo motor 601 is fixed to the lower end of the rotating sleeve 504 on the lower side of the lifting module pad 502, which drives the screw 602 to rotate. The screw 602 is rotatably mounted on the support plate 603 through the screw seat 605. The lifting nut seat 608, which is threadedly connected to the screw 602, is fixed to the inner side of the back plate 2. At the same time, the linear slide rail 604 on the support plate 603 cooperates with the linear slider 606 on the inner side of the back plate 2 for guidance, so that the back plate 2 slides up and down along the support plate 603 to achieve axial traction. The forward and backward swing servo motor 401, the left and right rotation servo motor 503, and the axial traction servo motor 601 are all equipped with brakes, which can keep the back plate 2 in a fixed position when the power is off, ensuring safety. The electrical box 9 provides power and control support for the device. The touch screen 10 serves as a human-machine interface for parameter setting and operation status display. With the help of IoT technology, it can also realize remote monitoring and data management, ensuring that the reset action is safe and traceable. The electrical box 9 is also equipped with a start button, a stop button and an emergency stop button, as well as a manual / automatic switch and an audible and visual alarm.

[0035] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
