Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a foldable scoliosis correction device. Background Art

[0002] Scoliosis is a common spinal deformity clinically classified as congenital scoliosis, degenerative scoliosis, and idiopathic scoliosis. It has become the third leading silent threat to children's health after myopia and obesity. It is both an X-ray sign and a clinical symptom, with a prevalence of 2%-3% in adolescents aged 10 to 18 years, with a significantly higher incidence in girls than boys. Idiopathic scoliosis (AIS) accounts for over 80% of all cases and is hereditary. Adolescence is the peak period for prevalence and represents a critical window for intervention. Once the disease develops, it can severely impact patients' lives. The appearance of the deformed spine affects their image and creates a psychological burden. If left untreated, it can progress to severe forms, impairing normal physiological activities such as breathing and movement, and even leading to altered gait. The differential force applied to the lateral sides of the body can lead to secondary joint deformities and musculoskeletal disorders such as osteoarthritis, severely impacting quality of life and even shortening life expectancy.

[0003] Currently, clinical treatments for scoliosis primarily include follow-up observation (self-adjustment), bracing, and surgical treatment. Scoliosis is clinically categorized as mild, moderate, and severe based on the Cobb angle. Mild scoliosis (Cobb angle less than 20 degrees) is generally recommended for observation and postural adjustment, along with regular checkups or appropriate bracing. Moderate scoliosis (Cobb angle between 20-40 degrees) requires bracing, such as the Boston brace and Milwaukee brace, to correct the spinal curvature through external support. Severe scoliosis (Cobb angle greater than 40 degrees) requires surgical intervention to prevent further deterioration and impact on physiological functions such as breathing and movement. Therefore, treatment for mild and moderate scoliosis is particularly important and crucial. Clinically, early intervention is recommended to prevent progression to severe scoliosis. However, for mild and moderate scoliosis, the existing brace-assisted orthopedic treatment methods have many shortcomings: ① Long wearing period and poor patient compliance: Brace wearing treatment requires extremely high patient compliance, and it needs to be worn for more than 18 hours a day. Most of the current braces are large-volume mechanical structures, which affect the patient's appearance. Long-term wearing of the brace is prone to local skin and soft tissue compression in the area where the brace contacts the body, and the patient often feels uncomfortable, which greatly affects the patient's normal life and work. It is often difficult to adhere to the standardized treatment cycle, especially for pediatric patients. The short treatment cycle and unsatisfactory treatment effect often make mild and moderate scoliosis worse. The condition develops into severe scoliosis; ② Insufficient precision correction: Most scoliosis braces currently lack a precisely adjustable design. The degree of scoliosis correction depends on the clinician's judgment of X-ray and CT images, which lacks timeliness and accuracy. The treatment effects vary greatly, and patients' families are often dissatisfied; ③ Expensive and large individual size differences: Orthopedic braces generally need to match the patient's body shape, and patients have large body differences. Personalized customization is expensive, increasing patients' medical expenses. Universal, cheap braces cannot be personalized and cannot meet the actual needs of clinical personalized treatment. This has become the main clinical contradiction for unsatisfactory scoliosis treatment results. Therefore, it is crucial to design a corrective brace that can improve scoliosis treatment compliance and meet personalized treatment requirements. Summary of the Invention

DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figure 1-12 This embodiment provides a scoliosis correction chair, including a main frame 1, a lifting mechanism 2, an adjustment chassis 3, a rotating mechanism 4, a tilting mechanism 5, a seat cushion 6, and a backrest 7. The adjustment chassis 3 is connected to the main frame 1 through the lifting mechanism 2, the rotating mechanism 4 and the tilting mechanism 5 are arranged on the adjustment chassis 3, and the seat cushion 6 includes a seat stool 61 and a hollow leg clamping plate 62. The seat stool 61 is arranged in the hollow area of ​​the leg clamping plate 62.

[0021] In this embodiment, the backrest 7 includes a curved backboard 71 for the patient's back to lean against, and a telescopic control mechanism 73 located on the concave side of the curved backboard 71. The telescopic control mechanism 73 includes two screws connected to the ends of the curved backboard 71 and an adjustment threaded cylinder threadedly connected to the two screws. The curved backboard 71 can slide up and down along the frame on which it is slidably mounted. The purpose of this up and down sliding is to adapt the curved backboard 71 to the natural curvature of the patient's spine when sitting high, ensuring the effectiveness of body correction. When the backrest matches the lordotic curvature of the patient's back spine, posture correction when sitting is more accurate and effective. The telescopic control mechanism 73 telescopes and adjusts along the patient's height, thereby adjusting the curvature of the curved backboard 71. The curved backboard 71 is densely provided with ventilation holes to increase the overall breathability of the area where the patient's back contacts the device, improving comfort and enhancing patient compliance with treatment. The curvature of the curved backboard 71 is adjusted through the telescopic control mechanism 73 to meet the usage needs of patients with different natural spinal curvatures. The adjustment of the curvature can improve the stability of the patient's back against the chair back and provide a stable basic support for subsequent front, back, left and right adjustments.

[0022] In this embodiment, the leg clamping plate 62 is provided with a recessed position for the patient's thigh to be placed. After the patient sits down, the recessed position can limit the base of the patient's thigh, which is beneficial to improve the adjustment accuracy under different posture adjustment positions. The leg clamping plate 62 is fixedly connected to the adjustment chassis 3 through four columns 63 and buffer springs 64 mounted on the columns 63. The design of the buffer spring 64 can decompose the shear force of the patient's own weight on the connection between the seat part 61 and the front and rear tilt deflection scale 535 when the patient tilts, and can alleviate the reaction force generated by the patient's own gravity at the moment of sitting down, thereby improving the patient's comfort. The main frame 1 also includes an armrest part 12 for auxiliary support when the patient sits down normally, as well as two front support feet 13, two rear wheels 14 and two foldable support frames 15 provided at the bottom of the main frame 1. The two foldable support frames 15 are trapezoidal when they are stretched together. The backrest part 7 and the two support frames 15 are both foldable. Figure 12As shown, the backrest portion 7 is rotatably mounted on the main frame 1 via a rotating fixing portion 16. The backrest portion 7 rotates within a certain angle range through the cooperation of the boss 163 on the rotating joint 161 and the abutment surface 164 and abutment surface 2 165 on the rotating joint 2 162. The abutment surface 164 can effectively prevent the backrest portion 7 from being excessively opened, thereby avoiding accidental injury to personnel. The direct contact surfaces of the rotating joint 161 and the rotating joint 2 162 have a certain degree of friction, which is a tight connection and requires external force to rotate. On the same level ground, the contact surface of the front support leg 13 and the contact surface of the rear wheel 14 are always on the same level, which can maintain the stability of the chair when the patient is sitting. In addition, the design of the front support leg 13 and the rear wheel 14 improves the convenience of the device's movement and the stability of the device when it is stationary. By rotating the fixing part, the maximum folding and opening angles of the U-shaped foldable support frame 15 are limited. When folded, it is parallel to the ground, and the maximum angle when opened is an obtuse angle (120-150 degrees), which can provide effective and stable support and ensure the stability of the entire chair when it lands on the ground.

[0023] In this embodiment, if Figure 4 As shown, a horizontal angle scale 411 , a left-right tilt deflection scale 525 , and a front-back tilt deflection scale 535 for indicating the adjustment amount are correspondingly provided on the rotating mechanism 4 , the first tilt portion 52 , and the second tilt portion 53 .

[0024] In this embodiment, the lifting mechanism 2 includes two single-fork hinges 21, two limiting slides 22, a horizontal slide bar 23 and a lifting adjustment screw 24. Each single-fork hinge 21 includes a first lower end 211 hinged to the main frame 1 and a second lower end 212 hinged to the horizontal slide bar 23. It also includes a first upper end 213 hinged to the bottom of the adjustment chassis 3 and a second upper end 214 slidably connected to the limiting slide 22. The limiting slide 22 is installed at the bottom of the adjustment chassis 3. The second upper end 214 of the single-fork hinge 21 slides through the slider. Connected to the limiting slide 22, the horizontal slide bar 23 is slidably mounted on the connecting rod 17 of the main frame 1. The lifting adjustment screw 24 is threadedly connected to the horizontal slide bar 23 through the threaded barrel 231. Rotating the lifting adjustment screw 24 drives the horizontal slide bar 23 to slide along the connecting rod 17. The second lower end 212 of the single fork hinge 21 is hinged to the horizontal slide bar 23. The sliding of the horizontal slide bar 23 will push the single fork hinge 21 up until the slider abuts the end side of the limiting slide 22. During the movement, the single fork hinge 21 moves upward against the adjustment chassis 3. The design of the threaded barrel 231 can prevent the lifting height from being retracted after the adjustment stops. The moving distance of the slider in the limiting slide 22 determines the maximum lifting distance of the lifting mechanism 2. The sliding distance range in the limiting slide 22 meets the height range required for lifting the seat. Different patients have different sitting heights and natural spinal curvatures. The patient's sitting height can be adjusted through the lifting mechanism 2 to meet the needs of patients with different sitting heights. At the same time, the lifted height can be recorded by a ruler, which is convenient for accurate recording of the patient's treatment process data and rapid adjustment and configuration of subsequent treatments.

[0025] In this embodiment, the rotating mechanism 4 includes a rotatable disk 41, a rotating adjustment worm 42, and a rotating worm wheel 43 that cooperates with the rotating adjustment worm 42. The rotating worm wheel 43 is coaxially fixedly connected to the center of the rotatable disk 41 and is located on both sides of the adjustment chassis 3. A handle is installed at the end of the rotating adjustment worm 42. Turning the handle can drive the rotating adjustment worm 42 to move, thereby driving the rotating worm wheel 43 to move. The rotating worm wheel 43 is coaxially fixedly connected to the center of the rotatable disk 41, so it also drives the rotatable disk 41 to rotate. The rotation angle of the rotatable disk 41 can be adjusted according to the horizontal angle ruler 411. The rotatable disk 41 is provided with two sets of positive and negative rotation scale angles to meet the different rotation posture requirements of different patients during the clinical correction process. The control of the rotation is achieved by the worm gear mechanism. On the one hand, it can prevent the backlash after adjustment, and on the other hand, it can achieve fine-tuning control of the rotation accuracy.

[0026] The handle of the rotary adjustment worm 42 can be folded into an "L" shape when not in use. When extended, it forms an "I-shaped crank" shape for easy operation. The rotating mechanism 4 realizes the horizontal rotation function of the body, which can meet the different correction needs of different patients. By adjusting the handle, the patient's body can be rotated horizontally to the left or right, and the rotation angle can be effectively recorded or controlled, providing the necessary measurement means for accurate correction treatment of patients.

[0027] In this embodiment, the tilting mechanism 5 includes a base portion 51 fixedly connected to the rotatable disk 41, a first tilting portion 52 provided on the base portion 51 in a spherical contact manner, and a second tilting portion 53 provided on the first tilting portion 52 in a spherical contact manner. The second tilting portion 53 is fixedly connected to the seat portion 61. The first tilting portion 52 realizes the tilt adjustment of the seat portion 61 in the left and right directions, and the second tilting portion 53 realizes the tilt adjustment of the seat portion 61 in the front and back directions.

[0028] Specifically, such as Figure 5-10As shown, the base portion 51 is a spherical support member with a spherical inner concave surface, and the first inclined portion 52 includes a hollow sphere 521 in contact with the spherical inner concave surface of the base portion 51, a first hinged rod 522 hinged at one end to the hollow sphere 521, and a first adjusting screw 523 rotatably mounted on the rotatable disk 41. The other end of the first hinged rod 522 is hinged to the first threaded rod sleeve 524, and the first threaded rod sleeve 524 is threadedly connected to the first adjusting screw 523. The second inclined portion 53 includes a sliding portion 531 that contacts the spherical surface of the hollow sphere 521, a second hinged rod 532 that is hinged at one end to the bottom of the seat portion 61, and a second adjusting screw 533 that is rotatably connected to the hollow sphere 521 through a hollow guide rod 537. The sliding portion 531 is fixedly connected to the seat portion 61 through a connecting piece 536. The sliding portion 531 is an arc segment. The hollow sphere 521 has a guide groove corresponding to the sliding portion 531. When adjusting, the sliding portion 531 slides along the guide groove. The other end of the second hinged rod 532 is hinged to the second threaded rod sleeve 534. The second threaded rod sleeve 534 is threadedly connected to the second adjusting screw 533. The hollow guide rod 537 is fixedly connected to the hollow sphere 521. The second adjusting screw 533 is sleeved in the hollow guide rod 537, and the hollow guide rod 537 has a groove for the second threaded rod sleeve 534 to move. The sliding portion 531 can also be a circular ring that contacts the spherical surface of the hollow sphere 521. Adjusting (forward and backward tilting) the second adjusting screw 533 drives the second threaded rod sleeve 534 to move along the groove on the hollow guide rod 537, thereby driving the second hinged rod 532 to move. The second hinged rod 532 drives the seat portion 61 to tilt forward and backward. During the tilting process, the tilt angle can be precisely adjusted by observing the angle indicated by the fore-and-aft tilt deflection scale 535. Adjusting (left-right tilting) the first adjusting screw 523 drives the first threaded rod sleeve 524 to move. The first threaded rod sleeve 524 drives the first hinged rod 522 to move. The first hinged rod 522 drives the seat portion 61 to tilt left and right. During the tilting process, the tilt angle can be precisely adjusted by observing the angle indicated by the left-and-right tilt deflection scale 525. The hollow sphere 521 is slidably connected to the base 51 in a spherical contact manner. The sliding portion 531 is also slidably connected to the hollow sphere 521 in a spherical contact manner. By cooperating with the hinged rod, screw, and screw sleeve to increase the external force, it can achieve tilt adjustment in the front, back, left, and right directions. During the sitting posture adjustment process, whether tilting left or right or forward and backward, the adjustment axis is always aligned with the center of the sphere, ensuring the accuracy of posture adjustment and the correction of the patient's scoliosis, which is conducive to the effectiveness of correction.

[0029] The operating principle of the scoliosis correction chair of this embodiment is as follows: The backrest 7 and the two foldable support frames 15 are unfolded to place the scoliosis correction chair stably on the ground. The patient sits on the scoliosis correction chair until his buttocks are completely pressed against the seat 61, and he puts his hands lightly on the armrests and sits up straight. At this time, the lifting adjustment screw 24 in the lifting mechanism 2 is adjusted according to the patient's actual sitting height and correction posture. During the adjustment process, the chassis 3 is adjusted to move upward along the scale 25 until it moves to the optimal position, and the lifting height is recorded; the patient's back is pressed against the curved backboard 71, and the telescopic control mechanism 73 is adjusted according to the feeling of the patient's back leaning until the back is completely aligned with the curved backboard 71; then, according to the patient's need for correction of posture, the second adjusting screw 533 is continued to be adjusted (forward and backward tilting) so that the seat 61 drags the patient's body forward or backward, and the forward and backward tilt deflection scale is used during the adjustment process. 535 will indicate different tilt angles until the desired angle is reached and the adjustment stops, recording the current forward / backward tilt angle value. The first adjustment screw 523 (for left and right tilt) is then adjusted so that the seat portion 61 pulls the patient's body to the left or right. During the adjustment process, the left and right tilt deflection scale 525 will indicate different tilt angles until the desired angle is reached and the adjustment stops, recording the current left / right tilt angle value. Finally, the rotation adjustment worm 42 in the rotation mechanism 4 is adjusted so that the patient's body can rotate horizontally. During the adjustment process, the horizontal angle scale 411 will indicate different rotation angles until the desired rotation angle is reached and the adjustment stops, recording the horizontal rotation angle value. After all the above adjustments are completed, the device remains unchanged, and the patient's scoliosis can be physically corrected in daily study and life. Different scoliosis patients have different treatment plans. For different patients, the scoliosis correction chair of this embodiment can be used to adapt to the corrective treatment of a specific patient by directly adjusting the corresponding angle. In subsequent treatment, based on the continuous adjustment of the treatment plan, one or more of the rotation angle, left and right tilt angle, and forward / backward tilt angle can be continuously adjusted.

[0030] In other embodiments, two limit rods extending along the lifting direction of the lifting mechanism 2 can be further provided on the main frame 1, and scales indicating the lifting height are marked on the limit rods. Corresponding through holes are provided on the adjustment chassis 3 and are slidingly connected to the two limit rods. This arrangement allows the adjustment chassis 3 to move along the scales on the limit rods during the adjustment process, thereby facilitating precise control of the lifting height value.

[0031] The scoliosis correction chair of this embodiment can make real-time multi-dimensional adjustment of the correction angle according to the examination results and diagnosis of different patients, including adjustment in directions such as spinal rotational deformity, lateral deformity, anterior-posterior deformity and complex deformity, to meet the treatment needs of different scoliosis patients in clinical practice, so that clinicians can more accurately correct the deformity of scoliosis patients, and the spinal correction treatment effect is more certain; it changes the previous way of spinal correction treatment by wearing a brace, and solves the compliance problem of scoliosis patients who are not used to wearing the brace for a long time and find it difficult to wear it for the entire treatment cycle. The patient compliance is good, and effective treatment can be carried out in real time during the patient's normal life and learning activities. The treatment means are integrated into the adjustment of the patient's daily living habits, which not only meets clinical needs, but also can adapt to the treatment of different scoliosis patients and meet the personalized needs of scoliosis treatment. The design of the lifting mechanism, rotating mechanism, tilting mechanism and backrest provides more accurate multi-dimensional visual control for spinal angle correction. In the process of adjusting the sitting posture, whether it is tilting left and right or tilting forward and backward, it is always ensured that the axis of adjustment always coincides with the center of the ball, ensuring the accuracy of posture adjustment and the accuracy of scoliosis correction of the patient; Scoliosis is divided into many types, such as spinal rotation deformity, lateral deformity, front-back deformity and complex deformity. Various types are clinically divided into mild, moderate and severe types, and different patients have different heights. Therefore, scoliosis correction treatment is actually a treatment plan that requires multi-dimensional comprehensive consideration. This embodiment integrates the backrest, lifting mechanism, rotation mechanism and tilting mechanism into one design, which realizes the simplicity of structure while ensuring the accuracy of each Each dimension can have sufficient correction range without interfering with each other, which has brought about a qualitative change in the efficacy of scoliosis correction. Through the design of this structure, the application of the spine under complex correction needs can be realized, such as independent adjustment of the sitting posture to the left, right, front and back. Through this independent adjustment, the correction of complex angles becomes clearer and feasible, providing more solutions for more patients with different scoliosis correction treatments, and setting more scientific correction parameters for patients according to the correction needs of different stages, providing rehabilitation doctors with convenient and accurate treatment operation control, and providing more effective treatment plans for scoliosis patients in clinical practice.

[0032] The above description is only a specific embodiment of the present invention. It should be pointed out that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be included in the scope of protection of the present invention.
