[0002] Scoliosis is a common spinal deformity with a high incidence in adults, especially in those over 60 years old, with a prevalence rate as high as 68%. Adult scoliosis mainly includes two types: degenerative scoliosis and adolescent scoliosis. Degenerative scoliosis is mostly caused by degenerative changes in the spine, while adolescent scoliosis is mostly caused by the lack of timely treatment or attention in the early stages. Adult scoliosis often causes symptoms such as low back pain, limb numbness, and difficulty walking, seriously affecting the patient's quality of life and ability to carry out daily activities.

[0003] At present, the treatment methods for scoliosis in adults mainly include conservative treatment and surgical treatment. Conservative treatment usually includes physical therapy, rehabilitation training and brace treatment. Although it can relieve symptoms to a certain extent, it is difficult for existing braces to fundamentally correct spinal deformities, and the treatment cycle is long, and patient compliance is poor. Although surgical treatment can effectively correct scoliosis, the surgical risk is high, especially for elderly patients, who are often accompanied by multiple comorbidities, have a long postoperative recovery time, and are at risk of complications such as infection and nerve damage. In view of the limitations and disadvantages of existing treatment methods, it is necessary to design a safe and effective scoliosis correction device to assist adult scoliosis patients in rehabilitation treatment.

DETAILED DESCRIPTION

[0020] To further explain the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings, in which the same reference numerals represent the same components.

[0021] See also Figure 1-5 This embodiment provides a scoliosis correction chair, including a base 1, a backrest 2 connected to the base 1, and a seat plate 3 installed on the base 1 via an adjustment mechanism. The adjustment mechanism includes a lifting component 4, a horizontal rotation component 5 and a tilting component 6. The lifting component 4 is connected to the base 1, the horizontal rotation component 5 is connected to the lifting part 41 of the lifting component 4, and the tilting component 6 is connected to the rotating part 51 of the horizontal rotation component 5.

[0022] In this embodiment, the tilting assembly 6 includes two connecting plates 61 that are parallel and fixedly connected to the seat plate 3, two hinged plates 62 whose upper sections are hinged to the two connecting plates 61, hinged sleeve rods 63 that are respectively hinged to the lower sections of the two hinged plates 62, and a locking assembly 64. The end of the rotating part 51 passes through the hinged sleeve rod 63 and extends to be hinged to the middle sections of the two connecting plates 61. The rotating part 51 is formed with a hinge limit portion 511 relative to the hinge sleeve rod 63. The hinge limit portion 511 is hinged to the hinge sleeve rod 63 and a limit tooth 513 is protruded on the outer side along the length direction of the hinge sleeve rod 63. The locking assembly 64 includes an engaging block 641, a connecting rod 642, a stopper 643, an elastic member 644, and a locking rod 645, a limit rod 646, and a locking rod 647 provided on the outside of the hinge sleeve rod 63. 46. ​​The engaging block 641 is fixedly connected to one end of the connecting rod 642. The elastic member 644 is sleeved on the outside of the connecting rod 642 and compressed between the engaging block 641 and the stop block 643. The elastic member 644 is a spring and is always kept in a compressed state. One end of the locking rod 645 is hinged to the outside of the hinge sleeve 63. The hinge sleeve 63 is provided with a limiting groove 631 at the other end relative to the locking rod 645. The other end of the locking rod 645 is hinged to one end of the limiting rod 646. The other end of the limiting rod 646 is hinged to the other end of the connecting rod 642 in the limiting groove 631. The connecting rod 642, the limiting groove 631, the limiting rod 646, and the locking rod 645 cooperate with each other to form a limiting structure. The engaging block 641 remains engaged with the limiting tooth 513 under the elastic force of the elastic member 644. The handle 65 is fixedly connected to the end of the hinge sleeve 63. The adjustment method of the tilt assembly 6 is to pull up the locking rod 645 to loosen the engaging block 641 from the limiting tooth 513, and manually adjust the tilt angle of the adjustment handle 65. After adjusting the tilt angle, release the locking rod 645, so that the engaging block 641 engages with the corresponding limiting tooth 513 on the hinge limiting part 511 under the elastic force of the elastic member 644, and the limiting rod 646 plays a role in limiting and preventing it from falling out.

[0023] In this embodiment, the horizontal rotation assembly 5 includes a fixed seat 52 fixedly connected to the lifting part 41 and a rotating disk 53, a slide rod 54, a slide 55, and a rotating screw 56 arranged on the fixed seat 52. The rotating disk 53 is rotatably connected to the fixed seat 52, the rotating part 51 is fixedly connected to the rotating disk 53, one end of the slide rod 54 is fixedly connected to the rotating disk 53 and the other end is slidably connected to the upper half of the slide 55, the fixed seat 52 is provided with a linear slide groove 521 relative to the slide 55, the lower half of the slide 55 is slidably installed in the linear slide groove 521, and the rotating screw 56 is passed through the linear slide groove 521 and is threadedly connected to the lower half of the slide 55. The rotating screw 56 drives the slide 55. The slide 54 slides within the slide 55 as it moves, thereby driving the rotating disk 53. The rotating disk 53 is fixedly connected to the rotating portion 51, thereby simultaneously driving the rotating portion 51. The rotating disk 53 is provided with two sets of positive and negative rotational scale angles to meet the different rotational posture requirements of different patients during clinical correction. Rotational control achieved through the slide 54, slide 55, and rotating screw 56 prevents backswing after adjustment and allows for fine-tuning of rotational accuracy. The horizontal rotation assembly 5 cooperates with the tilt assembly 6. By controlling the lateral rotation angle of the horizontal rotation assembly 5 and the precise tilt angle of the seat plate 3 by the tilt assembly 6, there is no need to adjust the seat plate's forward and backward tilt and left and right tilt positions separately. The coordinated rotation of the horizontal rotation assembly 5 and the tilt assembly 6 allows the combined position (correction position) to be set at once, achieving control of the final position of the combined position.

[0024] In this embodiment, the lifting assembly 4 includes an adjustment portion 42 rotatably connected to the base 1, a lifting screw 43 fixedly connected to the adjustment portion 42, and a lifting portion 41 threadedly sleeved on the outside of the lifting screw 43.

The height of the lift can be recorded using a ruler, facilitating accurate recording of patient treatment data and rapid adjustment of subsequent treatment configurations. Meanwhile, the seat plate 3 includes a seat cushion 31 and a base 32. The base 32 is fixedly connected to two connecting plates 61. The seat cushion 31 is rotatably mounted on the surface of the base 32 via rolling bearings 33. During the adjustment and rotation of the lifting screw 43, a rolling bearing 33 is designed under the seat cushion 31. When the patient sits on the seat and rotates horizontally, the body remains unchanged, providing technical support for subsequent correction.

[0025] In this embodiment, the backrest 2 features a through-hole for observing the patient's back. This design allows for monitoring the patient's progress during the correction process, facilitating smooth treatment. The backrest 2 is equipped with a belt 21 for securing the patient's body and two armrests 23 for resting the patient's hands. The horizontal rotation assembly 5 and the tilt assembly 6 are each equipped with a scale to indicate the adjustment amount, facilitating precise control of the adjustment. Four sliding wheels 11 are connected to the bottom of the base 1, each of which is equipped with a brake.

[0026] When in use, the patient sits on the correction chair until the buttocks are pressed against the seat cushion 31. First, adjust the adjustment part 42 of the lifting assembly 4 according to the patient's sitting height, so that the lifting part 41 drives the seat plate 3 to rise and fall to the optimal position, and then tie the belt 21 to the patient's waist. At this time, adjust the rotating screw 56 while observing the rotating scale to adjust the patient's body posture to the optimal correction position, then pull up the locking rod 645, manually adjust the inclination angle of the adjustment handle 65, and observe the scale in the middle of the articulated sleeve 63 while adjusting, and then start the normal correction of the patient. After the correction is completed, reset the various control mechanisms and unlock the belt.

[0027] The scoliosis correction chair of this embodiment does not require the seat to be individually adjusted in the forward and backward tilt and left and right tilt adjustments when correcting the patient's scoliosis. The horizontal rotation angle is controlled by the horizontal rotation component, and the forward and backward tilt angle is precisely controlled by the tilt component. After rotation, the compound position (correction position) is set at one time, which realizes the control of the final posture of the compound position and provides a more convenient treatment method for patients. The structure and function are optimized according to the special needs of scoliosis patients. Through scientific correction mechanism and ergonomic design, the correction chair can provide patients with stable and comfortable support, and at the same time realize gradual correction of the spine during daily use, alleviate symptoms, improve quality of life, and reduce dependence on traditional surgical treatment, providing a safe, effective and convenient solution for the rehabilitation treatment of adult scoliosis.

[0028] In other embodiments, the horizontal rotation assembly 5 may also be composed of a rotation adjustment worm and a worm wheel matched with the rotation adjustment worm, and the worm wheel is coaxially fixedly connected to the center of the rotating part.
