[0002] In recent years, with the wide popularity of electronic devices and the reduction of exercise time, the problem of scoliosis in young people is becoming more and more prominent, which is mainly caused by long-term bad sitting and standing posture, such as lying on the bed and sofa to watch mobile phones and televisions, habitually lifting the legs, bending the body, and supporting the head to sit, etc. In addition, there is a trend of combined deformation of front and rear scoliosis and left and right scoliosis, which greatly threatens the health of patients and even requires a large incision and high-difficulty spinal orthopedic surgery in severe cases.

[0003] At present, in addition to the traction bed for early correction of scoliosis, a more common way is to wear an orthopedic protector, which is generally worn on the patient's trunk. The orthopedic protector is customized or formed by 3D printing, and the patient's trunk is constrained by the orthopedic protector to assist the patient in gradually correcting scoliosis. However, a big problem with this orthopedic protector is that it cannot be adjusted adaptively according to the progress of the patient's condition (improvement of scoliosis), and re-customization greatly increases the medical cost of the patient. Moreover, the existing orthopedic protector is generally made of resin injection or printing, which not only has a large volume, but also is not convenient for storage and carrying, and also affects the normal activities of the patient after wearing.

[0026] As Figure 1The illustrated one kind spinal scoliosis modular correction device, mainly for the high and low shoulder condition of early middle stage patient of spinal scoliosis is corrected, the long-term abnormal contraction, stretching of surrounding muscle tissue is improved, the orthopedic of spinal scoliosis is realized.

[0027] The present application adopts wearable structure, and specifically can be regarded as a orthopedic clothes, as shown in Figure 1 It mainly includes shoulder module, waist module and traction module. The shoulder module and the waist module are respectively worn on the shoulder and the waist of the patient, and the traction module is used to realize the adjustment of the correction amount and the output of the lifting force.

[0028] As shown in Figure 1 The shoulder module includes a flexible shoulder sleeve 1, which is generally made of low-elastic or non-elastic textile. The two sides of the shoulder sleeve 1 are provided with arm loops 2 for the patient's hands to pass through, which can better fix the patient's hands on the shoulder. The arm loops 2 can be in the form of Velcro to adapt to different arm circumferences. Different sizes of shoulder sleeves 1 can be used to adjust the shoulder width, such as large, medium, small, etc. The shoulder sleeve 1 is provided with a hard shoulder buckle 3 opposite to the patient's two shoulders. A back plate 4 is provided on the back of the shoulder sleeve 1, and two shoulder pulleys 5 are symmetrically arranged on the top of the back plate 4. One of the shoulder buckle 3 and the back plate 4 serves as a connection node of the lifting rope described below, and the other serves as a mounting node of the shoulder pulley 5. In order to ensure stable transmission of the correction force, they are made of hard materials, such as hard plastic plates and metal plates. In order to ensure the connection strength, they are generally bonded once and then riveted twice.

[0029] The waist module includes a flexible waist sleeve 6, which is made of the same material as the shoulder sleeve 1 and has soft texture but cannot have too much elasticity to ensure stable transmission of the correction force. The front of the waist sleeve 6 is provided with an opening for the patient's waist to pass through. The opening can be connected by Velcro, multiple rows of zippers, etc., which can meet the needs of fixation and adjustment. The bottom of the waist sleeve 6 is symmetrically provided with two crotch belts 24 for the patient's legs to pass through, which can ensure the stability of the waist wear. The back of the waist sleeve 6 is provided with a waist plate 7, which is made of the same material as the shoulder buckle 3 and the back plate 4, such as plastic plates and metal plates. Its composite is similar to the back plate 4 described above. Two waist pulleys 8 are symmetrically arranged on the two sides of the waist plate 7.

[0030] As a core improvement point of the present application, the traction module includes a lifting rope system, which includes a lifting rope and a traction mechanism. The traction mechanism includes a locking assembly and a Y-shaped drive rod 9. As shown in Figure 2The lower end of the driving rod 9 is pinned in the center of the waist plate 7 and can swing left and right relative to the waist plate 7. The locking assembly is used to lock the position of the driving rod 9. The two forked ends of the driving rod 9 are used to be connected with the pulling rope system to drive the pulling rope, and the locking assembly is used to control the swinging angle of the driving rod 9.

[0031] The locking assembly has many specific structural forms, one of which is shown in Figure 2 The locking assembly includes a semicircular locking strip 0 fixedly arranged on the upper part of the center of the waist plate 7, and the locking strip 0 is provided with an arc-shaped swing opening 14. The locking assembly further includes a locking pin 15 arranged in the middle of the vertical section of the driving rod 9, the locking pin 15 is sleeved with a locking nut 16, the position of the locking pin 15 is opposite to the swing opening 14, the locking pin 15 is arranged in the swing opening 14, and the locking pin 15 is locked with the locking strip 0 through the locking nut 16. The locking assembly can effectively guide the swing of the driving rod 9 through the locking strip 0, and improve the stability of the movement.

[0032] As shown in Figure 1 The pulling system of the present application, that is, the pulling rope includes the upper left pulling rope 10, the lower left pulling rope 11, the upper right pulling rope 12 and the lower right pulling rope 13. One end of the upper left pulling rope 10 and the upper right pulling rope 12 is respectively fixedly connected with the shoulder buckle 3 on the two sides, and the other end is fixedly connected with the left and right two forks of the driving rod 9 after passing through the shoulder pulley 5. One end of the lower left pulling rope 11 and the lower right pulling rope 13 is respectively fixedly connected with the shoulder buckle 3 on the two sides, and the other end is fixedly connected with the left and right two forks of the driving rod 9 after passing through the waist pulley 8.

[0033] In use, the shoulder sleeve 1 and the waist sleeve 6 are respectively worn on the shoulder and the waist of the patient and are fixed, then the driving rod 9 and the pulling rope are fixed according to the design, the length of the pulling rope is ensured to be appropriate and in good contact with each pulley without slipping, a doctor adjusts the driving rod 9 according to the correction amount required by the patient, so that the driving rod 9 is adjusted towards the low side of the high-low shoulder of the patient, and with the swing of the driving rod 9, each pulling rope is driven to move, and the high-low shoulder is gradually corrected through the downward pulling of the high side and the upward pulling of the low side. After the driving rod 9 is positioned, the position of the driving rod 9 can be locked through the locking assembly. Subsequently, with the gradual improvement of the patient's condition, the doctor can adjust the swinging amount of the driving rod 9 according to the need, and then adjust the pulling force output by the driving rod 9 to adapt to the needs of the patient at different stages.

[0034] As shown in Figure 1As shown in the drawings, due to the swing degree of the driving rod 9, the driving amount of each lifting rope has certain difference, which will cause the imbalance of the action amount in the left lifting system (the upper left lifting rope and the lower left lifting rope), the right lifting system (the upper right lifting rope and the lower right lifting rope) or between the two lifting systems, that is, the difference of the rope movement length. For the products with low positioning price, the difference can be compensated by using the lifting rope with certain elasticity. Although the elasticity will cause certain correction force fluctuation, the overall price is relatively cheap and the universality is better.

[0035] However, it is better to use the low-elastic or even non-elastic steel strand for the lifting rope, and compensate the length difference of the lifting rope movement through other forms, such as Figure 3 As shown in the drawings, the self-swinging part 17 in V shape can be arranged at the two forked ends of the driving rod 9. The center of the self-swinging part 17 is arranged on the fork and rotates with the fork. The upper left lifting rope 10 and the lower left lifting rope 11 are fixed to the two ends of the self-swinging part 17 on the left side. The upper right lifting rope 12 and the lower right lifting rope 13 are fixed to the two ends of the self-swinging part 17 on the right side. The structure of the self-swinging part 17 is shown in Figure 4 As shown in the drawings, when the length difference exists in the left lifting system and the right lifting system or between the two systems, the self-swinging part 17 can change the angle relative to the driving rod 9 through the rotation, so as to automatically adapt to the length difference and realize the automatic error compensation. This way is also simple and low in cost, and will not sacrifice the stable transmission of the correction force of the lifting rope.

[0036] The specific installation structure of the self-swinging part 17 can refer to Figure 4 As shown in the drawings, the center pin 18 is arranged on one side of the center of the self-swinging part 17. The fork of the driving rod 9 is provided with the pin hole. The self-swinging part 17 is arranged in the pin hole and rotates with the fork through the center pin 18. In order to ensure the stable connection between the self-swinging part 17 and the lifting rope in long-term use, the lifting rope is not connected with the self-swinging part 17 in the form of complete fixation, but the short column 19 is arranged at the two ends of the self-swinging part 17. The ring groove 20 for sleeving the lifting rope is arranged on the circumferential surface of the short column 19. The rope ring is arranged at the end of the lifting rope opposite to the short column 19 and is sleeved in the ring groove 20. The rope ring has the rotation relative to the short column 19, which can eliminate the bending damage of the rope body caused by the angle change for a long time and ensure the service life. The lifting rope can be directly installed in the form of fixation in the stress direction of other fixed nodes.

[0037] In addition, the application can further set an elastic rope 21 between the middle sections of the left and right lower pull ropes 11 and 13, and the two ends of the elastic rope 21 are connected with the left and right lower pull ropes 11 and 13 respectively. The elastic rope 21 can form a tight and compact bundle for the middle sections of the left and right lower pull ropes 11 and 13. On this basis, in order to make the elastic rope 21, the left and right lower pull ropes 11 and 13 more compact, a circular supporting block 22 can be further set at the position where the left and right upper pull ropes 10 and 12 intersect with the elastic rope 21, the supporting block 22 is internally provided with a cross-shaped rope passing hole 23, and the left and right upper pull ropes 10 and 12 and the elastic rope 21 are all arranged in the rope passing hole 23.
