Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of the present application.

[0034] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of the present application. Figures 1 to 3 The present application provides an embodiment: a lumbar traction device convenient for patient adjustment, comprising an elastic band 1, which is composed of two intersecting elastic wide belts. Four fixed blocks 2 are fixedly connected to the outer four corners of the elastic band 1, and are located at the middle four corner positions of the elastic band 1. The bottom ends of adjacent fixed blocks 2 are fixedly connected with a traction extender 3, and the surface of the traction extender 3 is provided with a stretching and shrinking button, which is convenient for the patient to adjust the traction force. In addition, the top end and the bottom end of the shell of the traction extender 3 are fixedly connected with two fixed blocks 2 respectively, so as to effectively disperse the pulling force when the traction extender 3 works.

[0035] Two sticky pads 4 are fixedly connected to the two sides of the elastic band 1, and are respectively a sub-pad and a mother pad of a magic tape. The patient can wear the lumbar traction device by sticking the sub-pad to the mother pad. A rear waist pad 5 is fixedly connected to the middle of the elastic band 1, and directly adheres to the rear waist position of the patient, thereby providing support and buffering for the waist. A sticking belt 6 is fixedly connected to the side close to the adjacent sticky pad 4, and is used for fixing the elastic band 1 in cooperation with the sticky pad 4. The middle of the sticking belt 6 is fixedly connected to the bottom end of the rear waist pad 5, and the sticking belt 6 increases the fixation of the rear waist pad 5, so as to prevent the rear waist pad 5 from being displaced during use.

[0036] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of the present application. Figures 4 to 7 A through groove 7 is formed in the top end of the rear waist pad 5, and is longitudinally formed in the top end of the rear waist pad 5. A sliding rod 8 is slidably connected in the through groove 7, and the relative movement of the sliding rod 8 changes the protruding angle of a support plate 9 during traction. The top end of the sliding rod 8 is fixedly connected with the support plate 9, which directly contacts the posterior lumbar of the patient, thereby providing close support for the lumbar. During traction, the angle of the sliding rod 8 is adjusted, and the support plate 9 can adapt to the lumbar curve of different patients, thereby reducing the instability of the lumbar during traction.

[0037] The rear lumbar pad 5 is internally fixedly connected to a limit frame 10, which is used to limit the movement trajectory of the slide bar 8 and the power wheel plate 1 12 and the power wheel plate 2 13. A slide groove 11 is provided at the top of the limit frame 10, and the surface of the limit frame 10 is provided with slide grooves 11 in four directions. The outside of the slide bar 8 is slidably connected to the inner wall of the slide groove 11, and the inside of the slide groove 11 is slidably connected to the power wheel plate 12 and the power wheel plate 2 13. When the power wheel plate 12 and the power wheel plate 2 13 slide relative to each other, the turntable 16 is driven to rotate, and the turntable 16 drives the slide bar 8 to move within the slide groove 11 and the through groove 7 through the arc groove 17. The design of the slide bar 8 ensures its stability and accuracy during movement, and can quickly and accurately respond to the drive of other components to achieve precise adjustment of the angle of the support plate 9, providing the best support effect for the patient.

[0038] The outer sleeve of the power wheel plate 12 and the power wheel plate 2 13 is provided with a traction rope 14, and the horizontal traction rope 14 is sequentially wrapped around the pulley circumference of the power wheel plate 12 and the power wheel plate 2 13, and the free end of the traction rope 14 passes through the middle of the power wheel plate 2 13 and the back waist pad 5, so as to facilitate the patient to pull the traction rope 14.

[0039] The end of the traction rope 14 away from the power wheel plate 1 12 is fixedly connected to a pad 15. The outer portion of the pad 15 is bonded to the outer portion of the rear waist pad 5, and the outer portion of the pad 15 is bonded to the outer portion of the tape 6. The user pulls on the pad 15 to control the lateral retraction of the power wheel plate 2 13 relative to the power wheel plate 1 12, thereby adjusting the angle of the support plate 9. The material of the pad 15 is soft and has a certain degree of stickiness, which is convenient for the user to operate. At the same time, after the adjustment is completed, it can be firmly fixed in the corresponding position to ensure the stability of the angle of the support plate 9.

[0040] The interior of the limit frame 10 is provided with a limit member for adjusting the angle of the slide bar 8. The limit member includes a turntable 16. The outer portion of the turntable 16 is rotatably connected to the inner wall of the limit frame 10. An arc-shaped groove 17 is provided in the middle of the turntable 16. The outer portion of the slide bar 8 is slidably connected to the inner wall of the arc-shaped groove 17. There are four arc-shaped grooves 17. When the power wheel plate 12 and the power wheel plate 2 13 slide relative to each other, the bottom protrusions thereof slide in the arc-shaped groove 17, causing the turntable 16 to rotate. When the turntable 16 rotates, the longitudinal arc-shaped groove 17 synchronously drives the two slide bars 8 to move relative to each other. The lateral movement of the power wheel plate 12 and the power wheel plate 1 13 of the turntable 16 is converted into the longitudinal movement of the slide bar 8, thereby realizing the precise adjustment of the angle of the support plate 9. It has a compact structure and flexible rotation, and can realize complex motion conversion in a small space, thereby improving the overall performance of the tractor.

[0041] A positioning pad 27 is fixedly connected to the right side of the top of the tape 6, and the outer part of the traction rope 14 is slidably connected to the inner wall of the positioning pad 27. The function of the positioning pad 27 is to position the traction rope 14 to prevent it from deflecting or entangled during sliding, thereby ensuring the normal operation of the tractor.

[0042] refer to Figure 6 、 Figure 8 Two U-shaped blocks 18 are fixedly connected to the middle of support plate 9. The design of these blocks ensures a secure connection to support plate 9 while providing space for movement of internal adjustment components. An adjustment member for adjusting the tension of turntable 16 is located within U-shaped block 18. This adjustment member includes a shaft 19, which is rotatably connected to the middle of rear lumbar pad 5. A knob 20 is fixedly connected to the top of shaft 19, and an adjustment wheel 21 is fixedly connected to the bottom of shaft 19. Shaft 19 can drive adjustment wheel 21 to rotate.

[0043] A rack 22 is slidably connected to the front and rear sides of the U-shaped block 18. The outer teeth of the adjusting wheel 21 mesh with the outer teeth of the rack 22. The bottom end of the rack 22 is slidably connected to the top of the limit frame 10. The end of the rack 22 away from the adjusting wheel 21 is fixedly connected to the limit cylinder 23. A movable rod 24 is slidably connected to the inner part of the limit cylinder 23. When the adjusting wheel 21 rotates, it drives the rack 22 to move, and then drives the hook block 25 through the limit cylinder 23 to center the traction rope 14. The design of the rack 22 ensures its stability and accuracy during movement, and can quickly respond to the drive of the adjusting wheel 21 to achieve precise adjustment of the traction rope 14.

[0044] A hook block 25 is fixedly connected to the end of the movable rod 24 away from the U-shaped block 18. The top end of the hook block 25 engages with the outside of the turntable 16. The sliding of the traction rope 14 drives the hook block 25 to pull the tension spring 26, allowing the movable rod 24 to move within the limit cylinder 23, thereby adjusting the tension of the traction rope 14. The design of the movable rod 24 ensures its flexibility and stability during movement, enabling it to quickly respond to changes in the tension of the traction rope 14, adjusting the tension in a timely manner, and preventing the traction rope 14 from breaking due to excessive local force.

[0045] A tension spring 26 is sheathed around the exterior of the movable rod 24. The end of the tension spring 26, away from the U-shaped block 18, is fixedly connected to the inner wall of the retaining tube 23. The end of the tension spring 26, closer to the U-shaped block 18, is fixedly connected to the end of the movable rod 24, away from the hook block 25. When the traction rope 14 is subjected to force, the tension spring 26 adjusts the tension of the traction rope 14 by its own expansion and contraction, preventing the traction rope 14 from breaking due to localized excessive force. The elastic coefficient of the tension spring 26 has been precisely calculated to provide appropriate buffering and adjustment based on the force applied to the traction rope 14, ensuring the safety and stability of the tractor under various usage conditions.

[0046] A traction method for a lumbar traction device that is easy for patients to adjust. According to the above-mentioned lumbar traction device that is easy for patients to adjust, the specific method includes the following steps:

[0047] S1. Wearing and fixing: The patient fixes the elastic band to the lower back, uses the Velcro on the sticky pad 4 to ensure that the traction device is close to the waist, and makes the lower back pad 5 directly support the lower back and provide cushioning;

[0048] S2. Start traction: Press the buttons on the traction and retractor 3 on both sides of the waist to start the built-in motor, so that the traction and retractor 3 can be extended and retracted, driving the elastic belt 1 to stretch, thereby tractioning the patient's lumbar spine;

[0049] S3. Support plate angle adjustment: Based on the patient's comfort and condition, the patient pulls the pad 15 to retract the power wheel plate 2 13 laterally onto the power wheel plate 1 12, so that the protruding rods at the bottom of the power wheel plate 2 13 and the power wheel plate 1 12 slide in the transverse arc groove 17 of the turntable 16, causing the turntable 16 to rotate and synchronously drive the two slide rods 8 to slide relative to each other through the longitudinal arc groove 17, thereby changing the protruding angle of the support plate 9, reducing lumbar vertebral shaking during traction and improving the traction effect;

[0050] S4. Tension adjustment: By pulling the tension spring 26, the hook block 25 drives the movable rod 24 to move in the limiting cylinder 23, automatically adjusting the tension of the traction rope 14 to prevent breakage. If the elasticity of the traction rope 14 needs to be increased, the patient rotates the knob 20, the shaft 19 rotates, the adjusting wheel 21 engages with the rack 22, and the rack 22 drives the hook block 25 to center the traction rope 14, ensuring that the traction rope 14 is stable and reliable;

[0051] S5, end of traction: After the traction is completed, press the contraction button on the traction retractor 3 to retract the traction retractor 3 to release the traction on the lumbar spine, then untie the Velcro on the sticky pad 4 and remove the lumbar traction device.

[0052] Working Principle: During use, the user first places the elastic band 1 around the lower back and secures it with the Velcro on the adhesive pad 4, ensuring the lumbar traction device fits snugly against the waist. Then, by pressing the buttons on the traction retractors 3 on either side of the waist, the built-in motor is activated, activating the retraction mechanism of the traction retractors 3. This causes the retractors 3 to stretch the ends of the elastic band 1, thereby stretching and tractioning the patient's lumbar spine. During traction, the user can control the lateral retraction of power wheel plate 2 13 relative to power wheel plate 1 12 by pulling on the adhesive pad 15, depending on their personal comfort and medical needs. The relative sliding of power wheel plate 2 13 and power wheel plate 1 12 causes the protruding rods at their bottom ends to slide within the transverse arcuate groove 17 of the turntable 16, thereby causing the turntable 16 to rotate. As the turntable 16 rotates, the longitudinal arcuate groove 17 synchronously drives the two slide rods 8 to move relative to each other within the slide groove 11 of the limit frame 10 and the through groove 7 of the adhesive band 6. The relative movement of the slide bar 8 will change the protruding angle of the support plate 9. After adjusting the angle of the support plate 9, the pad 15 is fitted to the position of the tape 6 or the adhesive pad 4 and locked, thereby achieving the support of the support plate 9 for the posterior lumbar vertebrae of different patients, reducing the instability of the lumbar spine during traction and improving the traction effect.

[0053] Hook blocks 25 are provided at both ends of the traction rope 14. These hook blocks 25 reduce the obstruction of the traction rope 14 on the length of the slot of the longitudinal position limit frame 10 by pulling on both sides of the traction rope 14, effectively expanding the range of angle adjustment of the support plate 9. In addition, the hook blocks 25 are also equipped with a movable rod 24 and a tension spring 26. When the traction rope 14 is pulled, the sliding of the traction rope 14 will synchronously drive the hook blocks 25 to pull the tension spring 26, causing the movable rod 24 to move within the limit cylinder 23 to adjust the tension of the traction rope 14 and prevent the traction rope 14 from breaking due to local excessive force. By rotating the knob 20, the adjustment wheel 21 is driven to engage with the rack 22. The rack 22 drives the hook blocks 25 through the limit cylinder 23 to center the traction rope 14, thereby enhancing the elastic force of the traction rope 14, extending the service life of the traction rope 14, and ensuring the stability and reliability of the traction device.
