Description

Technical Field

[0001] The invention relates to medical orthopedic equipment, in particular to a modular scoliosis correction device. Background Art

[0002] In recent years, with the widespread popularization of electronic devices and the reduction of exercise time, the problem of scoliosis among adolescents has become increasingly prominent. It is mostly caused by long-term improper sitting or standing postures, such as lying on the bed or sofa to watch mobile phones or TV, long-term habitual sitting with legs crossed, hunched over, or sitting with the head supported, etc. In addition, the trend has changed from mainly anterior and posterior scoliosis in previous years to a combined deformation of anterior and posterior scoliosis and left and right scoliosis, which poses a great threat to the health of patients. In severe cases, large incisions and difficult spinal corrective surgery may be required.

[0003] At present, in addition to correction through traction beds, a common way to correct scoliosis in the past is to wear orthopedic braces. Generally, orthopedic braces are worn on the patient's torso. Orthopedic braces are customized or formed through 3D printing. Orthopedic braces are used to constrain the patient's torso, thereby assisting the patient in gradually correcting scoliosis. However, a big problem with this type of orthopedic brace is that it cannot be gradually adjusted adaptively according to the patient's disease progression (improvement of scoliosis), and re-customization greatly increases the patient's medical costs. In addition, existing orthopedic braces are generally made of resin injection molding or printing, which is not only large in size and inconvenient to store and carry, but also affects the patient's normal activities after wearing.

[0004] In the early and middle stages of scoliosis, a typical clinical manifestation is uneven shoulders. By applying lifting pressure to one of the two shoulders and pulling pressure to the other, the relaxation state of the muscles around the spine such as the waist and back can be improved to restore their normal physiological functions, which is very important for the correction of scoliosis in the early and middle stages. However, there is no related orthopedic protective gear in the existing technology. Summary of the invention

[0026] like Figure 1The modular scoliosis correction device shown is mainly used to correct the high and low shoulder conditions of patients with early and middle stage scoliosis, improve the long-term abnormal contraction and stretching of surrounding muscle tissue, and achieve correction of scoliosis.

[0027] The present invention adopts a wearable structure, which can be specifically regarded as a corrective garment, such as Figure 1 As shown in , it mainly includes a shoulder module, a waist module and a pulling module. The shoulder module and the waist module are worn on the patient's shoulders and waist respectively, and the pulling module is used to adjust the correction amount and output the lifting force.

[0028] like Figure 1 As shown in , the shoulder module of the present invention includes a flexible shoulder sleeve 1, which is generally made of low-elastic or inelastic textiles. Arm loops 2 for the patient's two hands to pass through are arranged on both sides of the shoulder sleeve 1. The patient's hands can be better fixed on the shoulders by passing through the arm loops 2. The arm loops 2 can be in the form of Velcro to adapt to arm circumferences of different sizes. The shoulder width can be roughly adjusted by setting different types of shoulder sleeves 1, such as: large, medium, small, etc. The shoulder sleeve 1 is provided with a hard shoulder buckle 3 at the position opposite to the shoulders of the patient on both sides. A back plate 4 is provided in the middle of the back of the shoulder sleeve 1, and two shoulder pulleys 5 are symmetrically provided on both sides of the top of the back plate 4. The shoulder buckle 3 and the back plate 4 are used as the connection node of the following lifting rope and the other as the installation node of the shoulder pulley 5. In order to ensure the stable transmission of the correction force, it is made of hard materials, such as: hard plastic plate, metal plate, etc. In order to ensure the connection strength, it is generally bonded for a first time and then riveted for a second time.

[0029] The waist module includes a flexible waist sleeve 6. The material of the waist sleeve 6 is consistent with that of the shoulder sleeve 1. The texture is soft, but not too elastic, to ensure the stable transmission of the correction force. The front of the waist sleeve 6 is provided with an opening for the patient's waist to be inserted. The opening can be connected by means of Velcro, multiple rows of zippers, etc., to meet the needs of fixation and adjustment. Two crotch straps 24 for the patient's legs to be inserted are symmetrically arranged at the bottom of the waist sleeve 6 to ensure the stability of wearing at the waist. A waist plate 7 is arranged on the back of the waist sleeve 6. The material of the waist plate 7 is the same as that of the shoulder buckle 3 and the back plate 4, such as a plastic plate, a metal plate, etc. The composite is similar and can also refer to the aforementioned back plate 4. Two waist pulleys 8 are symmetrically arranged on both sides of the waist plate 7.

[0030] As a core improvement of the present invention, the pulling module includes a pulling rope system, which includes a pulling rope and a pulling mechanism, and the pulling mechanism includes a locking assembly and a Y-shaped driving rod 9. Figure 2As shown in the figure, the lower end of the driving rod 9 is pinned to 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 connect with the lifting rope system to drive the lifting rope, and the locking assembly is used to control the left and right swing angle of the driving rod 9.

[0031] There are many specific structural forms of the locking component, one of which is Figure 2 As shown in: it includes a semicircular locking strip 0 fixedly arranged at the center upper part of the waist plate 7, and an arc-shaped swing opening 14 is arranged on the locking strip 0. The locking assembly also includes a locking pin 15 arranged in the middle of the vertical section of the driving rod 9, and a locking nut 16 is sleeved on the locking pin 15. The position of the locking pin 15 is opposite to the swing opening 14. The locking pin 15 is inserted into the swing opening 14 and is locked with the locking strip 0 through the locking nut 16. This locking assembly can effectively guide the swing of the driving rod 9 through the locking strip 0, thereby improving the stability of its movement.

[0032] like Figure 1 As shown, the lifting system of the present invention, that is, the lifting rope includes an upper left lifting rope 10, a lower left pulling rope 11, an upper right lifting rope 12 and a lower right pulling rope 13. One end of the upper left lifting rope 10 and the upper right lifting rope 12 are respectively fixed to the shoulder buckles 3 on both sides, and the other end passes through the shoulder pulley 5 and is fixed to the left and right forks of the driving rod 9. One end of the lower left pulling rope 11 and the lower right pulling rope 13 are respectively fixed to the shoulder buckles 3 on both sides, and the other end passes through the waist pulley 8 and is fixed to the left and right forks of the driving rod 9.

[0033] During use, the shoulder sleeve 1 and waist sleeve 6 are worn on the patient's shoulders and waist respectively and fixed, and then the driving rod 9 and the lifting rope are fixed as designed to ensure that the lifting rope is of appropriate length and in good contact with each pulley without slipping; the doctor bends the driving rod 9 according to the correction amount required by the patient, so that the driving rod 9 is bent toward the lower side of the patient's uneven shoulders. As the driving rod 9 swings, it can drive the lifting ropes to move, and gradually correct the uneven shoulders by pulling down the high side and lifting up the low side. After the driving rod 9 is positioned, its position can be locked by the locking assembly; subsequently, as the patient's condition gradually improves, the doctor can adjust the swing amount of the driving rod 9 as needed, and then adjust the lifting force output by the driving rod 9 to meet the needs of the patient at different stages.

[0034] like Figure 1As shown in the figure, since the swing degree of the driving rod 9 has a certain difference in the driving momentum of each pulling rope, this difference will cause an imbalance in the amount of movement inside the left pulling system (upper left pulling rope, lower left pulling rope), inside the right pulling system (upper right pulling rope, lower right pulling rope) or between the pulling systems on both sides of the present invention, that is, the difference in the movement length of the rope. For generally positioned and low-priced products, this difference can be compensated by adopting a pulling rope with a certain elasticity. Although the elasticity will cause a certain fluctuation in the correction force, it is generally cheaper and more versatile.

[0035] However, a better approach is that the pull rope still uses low-elasticity or even inelastic steel strands, and compensates for the length difference of the pull rope movement in other ways, such as Figure 3 As shown in the figure, the present invention can be provided with a V-shaped self-swinging member 17 at the two forked ends of the driving rod 9, and the center of the self-swinging member 17 is installed on the fork of the driving rod 9 and forms a rotational fit with the fork. The upper left lifting rope 10 and the lower left pulling rope 11 are fixedly connected to the two ends of the self-swinging member 17 located on the left side. The upper right lifting rope 12 and the lower right pulling rope 13 are fixedly connected to the two ends of the self-swinging member 17 located on the right side. The structure of the self-swinging member 17 is as shown in FIG. Figure 4 As shown in the figure, by setting the self-swinging member 17, when there is a difference in the movement length within the left lifting system and the right lifting system or between the two, the self-swinging member 17 can rotate to change its angle relative to the driving rod 9, thereby automatically adapting to the difference in movement length and realizing automatic error compensation. This method is also relatively simple and low in cost, and at the same time, it will not sacrifice the stable transmission of the correction force by the lifting rope.

[0036] The specific installation structure of the self-swinging member 17 can refer to Figure 4 As shown in , a center pin 18 is provided on one side of the center of the self-swinging member 17, and a pin hole is provided on the fork of the driving rod 9. The self-swinging member 17 is inserted into the pin hole, and the center pin 18 forms a rotational fit with the fork. At the same time, in order to ensure the stable connection between the self-swinging member 17 and the pulling rope in long-term use, the pulling rope is not connected to the self-swinging member 17 in a completely fixed form, but short columns 19 are provided at both ends of the self-swinging member 17, and an annular groove 20 for the pulling rope to be sleeved is provided on the peripheral surface of the short column 19. A rope loop is provided at the end of the pulling rope opposite to the short column 19, and is sleeved in the annular groove 20 through the rope loop. The rope loop is rotatable relative to the short column 19. Compared with the direct fixing form, it can eliminate the bending damage to the rope body caused by long-term angle changes and ensure its service life. Since the force direction of the pulling rope at other fixed nodes is relatively stable, it can be directly installed in a fixed form.

[0037] In addition, the present invention can also be provided with an elastic cord 21 between the middle sections of the lower left pull cord 11 and the lower right pull cord 13, and the two ends of the elastic cord 21 are respectively connected to the lower left pull cord 11 and the lower right pull cord 13. The elastic cord 21 can form a tight band for the middle sections of the lower left pull cord 11 and the lower right pull cord 13. On this basis, in order to make the elastic cord 21, the lower left pull cord 11 and the lower right pull cord 13 more regularly gathered, a circular support block 22 can be provided at the position where the upper left lifting cord 10 and the upper right lifting cord 12 intersect with the elastic cord 21, and a cross-shaped rope threading hole 23 is provided in the support block 22, and the upper left lifting cord 10, the upper right lifting cord 12 and the elastic cord 21 are all inserted in the rope threading hole 23.
