Description

Technical Field

[0001] The present invention relates to the technical field of medical rehabilitation equipment, and in particular to a dynamic bionic scoliosis orthosis capable of accurately controlling continuous force. Background Art

[0002] Scoliosis refers to a complex three-dimensional deformity of one or more segments of the spine with coronal scoliosis, sagittal kyphosis / lordosis, and horizontal vertebral rotation. The application of scoliosis, orthoses, and related technologies is an important intervention for early detection and early treatment. Orthoses can effectively control the progression of spinal deformity, delay the natural course of EOS and AS progression, and reduce the degree of surgical intervention. It is currently the only non-surgical treatment method that can prevent the natural progression of EOS and AS.

[0003] At present, the correction mechanism of any type of orthosis for spinal deformity is to apply forces and torques in opposite directions on the patient's body surface to the spine through the principle of three-point mechanics or four-point mechanics, so as to change the load of the spine in three-dimensional space growth, assist the patient in spinal correction, and promote its normal growth through the Hueter-Volkmann law. The theoretical basis for orthosis correction of scoliosis is still: 1. Three-point or four-point force system in the coronal plane; 2. Local force pair system; 3. Sagittal spinal balance. In addition, the Hueter-Volkmann law also provides a basis for orthosis treatment.

[0004] At present, all types of orthotics are made according to the patient's scoliosis (coronal plane, scoliosis plane, vertebral rotation) to take a model, and are made and worn at one time. The main problems are as follows: 1. If the scoliosis correction is not satisfactory or the scoliosis angle changes during the wearing of the orthosis, it cannot be adjusted dynamically, and a new orthosis can only be made and worn again, resulting in poor treatment effect or failure. In short, correction is a long process. As the correction progresses, the scoliosis will deform, but it is difficult for the orthosis to adjust the correction angle and strength as the scoliosis changes, and the ideal effect cannot be achieved.

[0005] 2. The orthosis produced by one-step molding exerts a large force on the body, which can easily cause discomfort or even pain during the adaptation period. Patients cannot persist and treatment fails. For example, a scoliosis corrector disclosed in CN109288617A has a relatively fixed correction structure and is difficult to adjust, and is therefore not adaptable to different scoliosis patients. 3. The biomechanics of current orthoses are mainly based on horizontal plane compression, lacking longitudinal force, especially continuous longitudinal force, and the correction effect is limited; 4. Most scholars agree that orthoses are only suitable for patients with a Cobb angle of less than 30 degrees. Summary of the invention

[0006] In order to solve the problem that existing orthoses are made in one piece and it is difficult to dynamically adjust the force, resulting in unsatisfactory orthotic treatment effects, the present invention provides a dynamic bionic scoliosis orthosis with a precisely controlled continuous force. The lateral stretching combined with the longitudinal force can increase the treatment effect of the orthosis. At the same time, the force is precisely controllable, providing a slow and continuous force, which can flexibly adapt to patients with different scoliosis conditions and expand the scope of application of the orthosis.

[0007] To achieve the above purpose, the technical solution adopted by the present invention is: A dynamic bionic scoliosis orthosis with a precisely controlled continuous force, worn on a human trunk, comprises a front longitudinal orthosis plate, a rear longitudinal orthosis plate, a transverse orthosis unit and an orthosis brace, wherein the front longitudinal orthosis plate and the rear longitudinal orthosis plate are respectively arranged longitudinally on the front and rear sides of the human trunk, so as to provide a basis for the correction of the spine, wherein the front longitudinal orthosis plate and the rear longitudinal orthosis plate provide a force in the vertical direction of the human trunk to correct the spine, and the front longitudinal orthosis plate and the rear longitudinal orthosis plate are a kind of telescopic structure or a fixed structure, so as to provide a force in the vertical direction; The transverse correction unit provides a force in the horizontal direction of the human body to correct the spine. Multiple groups of the transverse correction units are arranged on the front longitudinal correction plate and the rear longitudinal correction plate, thereby realizing the combination of the transverse force and the longitudinal force. The multiple groups of transverse correction units are arranged at intervals in the upper, middle and lower parts. Each group of transverse correction units includes a fixed plate and a movable plate that can be adjusted on one side of the fixed plate. The fixed plate can be detachably arranged on the front longitudinal correction plate and the rear longitudinal correction plate. Under the premise that the fixed plate does not move, the distance between the fixed plate and the movable plate is adjustable; The orthopedic brace includes a brace 1, a brace 2 and a brace 3 which are arranged in sequence outside the human trunk from top to bottom. The brace 1, the brace 2 and the brace 3 are respectively detachably arranged between the transverse orthopedic units at the upper, middle and lower parts of the front longitudinal orthopedic plate and the rear longitudinal orthopedic plate. Different braces fit different parts of the human trunk.

[0008] Furthermore, the front longitudinal orthosis plate and the rear longitudinal orthosis plate are both fixed structures, or the front longitudinal orthosis plate and the rear longitudinal orthosis plate are both telescopic structures, or the front longitudinal orthosis plate is a fixed structure and the rear longitudinal orthosis plate is a telescopic structure, or the front longitudinal orthosis plate is a telescopic structure and the rear longitudinal orthosis plate is a fixed structure. It is convenient to select a fixed structure or a telescopic structure according to the patient's scoliosis condition.

[0009] Furthermore, the front longitudinal orthotic plate and the rear longitudinal orthotic plate are telescopic structures, and the front longitudinal orthotic plate and the rear longitudinal orthotic plate are thin plates with adjustable lengths. The front longitudinal orthotic plate and the rear longitudinal orthotic plate both include a lower plate, an upper plate and a screw lifting mechanism. The upper plate is slidably arranged above the lower plate to facilitate relative extension and retraction. There is an overlap between the lower plate and the upper plate, and the screw lifting mechanism for adjusting the relative distance between the lower plate and the upper plate is arranged between the lower plate and the upper plate to facilitate the sliding of the upper plate.

[0010] Furthermore, guide plates are symmetrically arranged on both sides of the upper part of the lower plate, and the upper plate is slidably arranged between the guide plates on both sides, so as to provide guidance for the sliding of the upper plate and avoid the deviation of the moving direction of the upper plate. The lower plate is extended upward from the upper end of the upper plate, and the arrangement direction of the upper plate is consistent with the arrangement direction of the lower plate. The screw lifting mechanism includes a quadrilateral mechanism arranged in a diamond shape and a bidirectional screw for driving the quadrilateral mechanism to move. The upper and lower hinge points of the quadrilateral mechanism are respectively connected to the lower end of the upper plate and the lower plate. The bidirectional screw is arranged in a direction perpendicular to the arrangement direction of the upper plate. The bidirectional screw facilitates the adjustment of the height of the quadrilateral mechanism, thereby controlling the upper plate and the lower plate to move closer or farther away from each other.

[0011] Further, or, the front longitudinal orthosis plate and the rear longitudinal orthosis plate are fixed structures, and the front longitudinal orthosis plate and the rear longitudinal orthosis plate are thin plates with fixed lengths. In this case, the lengths of the front longitudinal orthosis plate and the rear longitudinal orthosis plate are fixed and cannot be adjusted.

[0012] Furthermore, the front longitudinal orthotic plate and the rear longitudinal orthotic plate are each provided with three rows of mounting holes, and the number of mounting holes in each row is a number of holes arranged equidistantly up and down. The transverse orthotic unit is detachably connected to the front longitudinal orthotic plate and the rear longitudinal orthotic plate through any of the mounting holes, so as to facilitate adjustment of the installation height position of the transverse orthotic unit. Multiple groups of the transverse orthotic units are arranged on both sides of the front longitudinal orthotic plate and the rear longitudinal orthotic plate, and the multiple groups of transverse orthotic units are arranged in parallel.

[0013] Furthermore, the two sides of the fixed plate are connected with the mounting holes by screws, which facilitates the disassembly and assembly of the fixed plate and the adjustment of the installation position. The movable plate and the fixed plate are located on the same plane. The movable plate is longer than the fixed plate and can be connected to the orthopedic brace in a larger range. The movable plate is connected with the orthopedic brace by screws. A hand screw is provided between the movable plate and the fixed plate, and the hand screw is used to conveniently drive the movable plate to move its position. A fixed threaded barrel is provided in the middle of the fixed plate, and a hand screw is connected to the inner thread of the fixed threaded barrel. A movable circular ring sleeve is provided on the movable plate, and one end of the hand screw extends into the movable circular ring sleeve and is rotatably connected to the movable circular ring sleeve. A limiting rod is also provided on the hand screw, and the limiting rod is arranged at both ends of the movable circular ring sleeve.

[0014] Furthermore, the orthopedic brace is a curved shell-like structure that fits the corresponding part of the human trunk; the brace one is connected to the upper chest of the human trunk, and the brace one is a left-right split structure, which supports the upper chest in at least two directions; the brace two is connected to the waist and abdomen of the human trunk, and the brace two is at least two pieces, which supports the waist and abdomen in at least two directions; the brace three is connected to the hip of the human trunk, and the brace three is arranged in a ring to support the hip and buttocks.

[0015] Through the above technical solution, the beneficial effects of the present invention are: The structural design of the present invention is reasonable, and the three-point or four-point force of the existing orthosis is changed from one-time molding to a slowly continuous force that can be precisely controlled. The longitudinal force can be adjusted by the front longitudinal orthosis plate and the rear longitudinal orthosis plate of the telescopic structure, and the lateral force can be adjusted by the transverse orthosis unit. In this way, the lateral and longitudinal slowly continuous forces that can be precisely controlled are combined, so that the existing rigid orthosis can be optimized into a dynamic three-dimensional orthosis that can be precisely adjusted.

[0016] The orthopedic brace of the present invention includes a plurality of braces that fit the corresponding parts of the human body, which can conveniently support the parts of the human body. The orthopedic brace is installed by screws, which is convenient to wear on the human body trunk. The longitudinal force of the human body trunk is provided under the action of the front longitudinal orthopedic plate and the rear longitudinal orthopedic plate, while the transverse orthopedic unit provides the transverse force, so that the slow and continuous stretching that can be accurately adjusted can be performed, thereby correcting the scoliosis well.

[0017] The front longitudinal orthosis plate, the rear longitudinal orthosis plate and the transverse orthosis unit of the present invention are all adjusted by means of threads, which is convenient, flexible and accurate to adjust the force of the stretch correction, which can avoid the discomfort and pain caused by the large correction force applied, and ensure the continuous correction force. At the same time, the application of the thread adjustment means improves the versatility of the front longitudinal orthosis plate, the rear longitudinal orthosis plate and the transverse orthosis unit, and can adapt to the treatment of patients with different scoliosis. The installation position of the transverse orthosis unit is adjustable, which is convenient for correcting scoliosis occurring in different positions.

[0018] The three-point or four-point continuous force on the coronal plane of the present invention combined with the longitudinal force can greatly increase the therapeutic effect of the orthosis. The force adjustment is achieved through the thread, and the force adjustment has the characteristics of precise controllable and slow continuous stretching, so that the body gradually adapts to the force, greatly increasing the comfort of orthosis treatment and improving the therapeutic effect. The precise and controllable slow continuous force can dynamically adjust the applied force during orthosis treatment, greatly increasing the scope of application and therapeutic effect of the orthosis.

[0019] The present invention provides longitudinal force through front and rear longitudinal orthopedic plates, and transverse orthopedic units can be flexibly arranged on the longitudinal orthopedic plates, which can enable the orthosis to be flexibly adjusted according to the scoliosis condition and the position of the top vertebra. The transverse orthopedic unit provides transverse force, and the longitudinal force is combined with the transverse force, so that the orthosis can accurately and dynamically adjust the force to ensure the treatment effect. While the longitudinal force is adjusted, the position of the transverse orthopedic unit corresponding to the top vertebra position remains unchanged, and thus the transverse force remains unchanged.

DETAILED DESCRIPTION

[0032] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings: like Figure 1 to Figure 11 As shown, a dynamic bionic scoliosis orthosis with a precisely controlled continuous force is worn on a human trunk, and comprises a front longitudinal orthosis plate 1, a rear longitudinal orthosis plate 2, a transverse orthosis unit 3 and an orthosis brace 4. The orthosis can provide a precisely controllable slow continuous force in the transverse and longitudinal stretching directions, thereby improving the therapeutic effect of the orthosis.

[0033] The front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 are used to provide longitudinal force. The front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 are respectively arranged longitudinally on the front and back sides of the human body trunk. In short, the front longitudinal orthosis plate 1 can be arranged on the front chest of the human body, and the rear longitudinal orthosis plate 2 can be arranged on the back of the human body. The front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 provide force in the vertical direction of the human body trunk to correct the spine, such as Figure 1~Figure 3 Show.

[0034] In this embodiment, the front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 are a kind of telescopic structure or fixed structure. Specifically, the front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 can both be fixed structures; or the front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 can both be telescopic structures; or the front longitudinal orthosis plate 1 is a fixed structure and the rear longitudinal orthosis plate 2 is a telescopic structure; or the front longitudinal orthosis plate 1 is a telescopic structure and the rear longitudinal orthosis plate 2 is a fixed structure. Therefore, the front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 can choose different fixed or telescopic structures, so as to flexibly adapt to the scoliosis conditions of different patients.

[0035] If the front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 are fixed structures, the front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 are thin plates of fixed length. Here, the front and rear longitudinal orthosis plates can be made of thin steel sheets, which can be bent and deformed by external forces, such as Figure 4 If the front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 are telescopic structures, the front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 are thin plates with adjustable lengths, and the thin plates can be bent and deformed. By changing the lengths of the front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2, different degrees of longitudinal forces can be provided, such as Figure 5The front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 of the telescopic structure can be placed upright or inverted.

[0036] Under the premise that the front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 are telescopic structures, the front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 both include a lower plate 5, an upper plate 6 and a screw lifting mechanism 7, such as Figure 6 and Figure 7 As shown. The upper plate 6 and the lower plate 5 are both independent thin plates, and the arrangement direction of the upper plate 6 is consistent with that of the lower plate 5, that is, the upper plate 6 and the lower plate 5 are arranged on a vertical line, and there is an overlap between the lower plate 5 and the upper plate 6. The upper plate 6 is slidably arranged above the lower plate 5, and then the upper plate 6 can slide on the basis of the fixed lower plate 5, which forms a telescopic structure and changes the distance between the upper plate 6 and the lower plate 5.

[0037] In order to guide the sliding of the upper plate 6, guide pieces 8 are symmetrically arranged on both sides of the upper part of the lower plate 5. The guide pieces 8 are bent into a "﹁" shape. After the guide pieces 8 on both sides are connected and assembled with the lower plate 5, the cross section is an open rectangular flat tube shape, that is, one side wall of the rectangular flat tube is disconnected and open in the middle. There is a gap between the guide piece 8 and the lower plate 5 for the purpose of facilitating the insertion of the upper plate 6. One end of the guide piece 8 is bent and connected to the lower plate 5, and then the upper plate 6 is arranged between the guide pieces 8 on both sides for sliding, and the upper end of the upper plate 6 extends upward from the lower plate 5. The guide piece 8 can prevent the upper plate 6 from deflecting when moving.

[0038] In order to adjust the position of the upper plate 6, a screw lifting mechanism 7 is used here, that is, a screw lifting mechanism 7 is provided between the lower plate 5 and the upper plate 6, and the screw lifting mechanism 7 can adjust the relative distance between the lower plate 5 and the upper plate 6. The screw lifting mechanism 7 is close to the lower part of the lower plate 5, so that the overlapping distance between the lower plate 5 and the upper plate 6 is longer, and the height position of the screw lifting mechanism 7 will change when the front longitudinal orthopedic plate 1 and the rear longitudinal orthopedic plate 2 are placed upright or inverted.

[0039] The screw lifting mechanism 7 includes a quadrilateral mechanism 71 arranged in a diamond shape and a bidirectional screw 72 for driving the quadrilateral mechanism 71. The quadrilateral mechanism 71 includes four connecting rods arranged in a diamond shape, and two adjacent connecting rods are hinged by bolts, so that the left and right spacing of the quadrilateral mechanism 71 can be adjusted, and its height changes while the left and right spacing is adjusted.

[0040] The left and right hinge points of the quadrilateral mechanism 71 are suspended and not connected to the upper plate 6 and the lower plate 5. The upper and lower hinge points of the quadrilateral mechanism 71 are connected to the lower end of the upper plate 6 and the lower plate 5 respectively. The position of the hinge point at the bottom of the quadrilateral mechanism 71 is fixed, and the position of the hinge point at the top will change up and down. This change means that the upper plate 6 is moving. When the quadrilateral mechanism 71 is adjusted, the upper plate 6 and the lower plate 5 are relatively extended and retracted. Figure 8 shown.

[0041] The arrangement direction of the bidirectional screw 72 is perpendicular to the arrangement direction of the upper plate 6. When the bidirectional screw 72 is installed, a movable threaded barrel 9 is arranged at the hinge points on the left and right sides of the quadrilateral mechanism 71, and the movable threaded barrels 9 on both sides are located on the same horizontal line. The thread rotation directions on both sides of the bidirectional screw 72 are different, and the two sides of the bidirectional screw 72 are respectively threadedly connected with the movable threaded barrel 9.

[0042] The adjustment principle of the telescopic structure is as follows: after the bidirectional screw 72 is turned, the movable threaded cylinders 9 on both sides can move closer or farther away from each other, and then the height of the quadrilateral mechanism 71 can be extended or shortened. The relative spacing between the upper plate 6 and the lower plate 5 can be changed by the quadrilateral mechanism 71, so as to achieve the purpose of length telescopic adjustment. In order to facilitate the operation of the bidirectional screw 72, a prism 10 is provided in the middle of the bidirectional screw 72. The axis of the prism 10 and the bidirectional screw 72 are consistent. By operating the prism 10 with a tool, it is convenient to drive the bidirectional screw 72 to operate, so as to achieve the function of adjusting the length of the front longitudinal orthopedic plate 1 or the rear longitudinal orthopedic plate 2.

[0043] The transverse correction unit 3 provides a force in the horizontal direction of the human body trunk, that is, the transverse correction unit 3 can provide a three-point or four-point continuous force on the coronal plane, thereby correcting the spine. Three groups of transverse correction units 3 are arranged on the front longitudinal correction plate 1 and the rear longitudinal correction plate 2. The three groups of transverse correction units 3 are arranged at intervals in the upper, middle and lower parts, and are kept parallel from top to bottom. The number of each group of transverse correction units 3 is two, and the two transverse correction units 3 are arranged on the left and right sides of the front longitudinal correction plate 1 and the rear longitudinal correction plate 2.

[0044] If the front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 are telescopic structures, the three groups of transverse orthosis units 3 are arranged on the upper plate 6 and the lower plate 5. If the front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 are fixed structures, the three groups of transverse orthosis units 3 can be arranged at any height position on the front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2. Each group of transverse orthosis units 3 includes a fixed plate 31 and a movable plate 32 which is adjustably arranged on one side of the fixed plate 31, so that the distance between the fixed plate 31 and the movable plate 32 is adjustable, such as Fig. 9 shown.

[0045] When the fixing plate 31 is installed, the fixing plate 31 can be detachably arranged on both the front longitudinal orthotic plate 1 and the rear longitudinal orthotic plate 2. Specifically, three rows of mounting holes 12 are provided on the front longitudinal orthotic plate 1 and the rear longitudinal orthotic plate 2, and the number of mounting holes 12 in each row is a number of holes 12 arranged equidistantly up and down. The transverse orthotic unit 3 is detachably connected to the front longitudinal orthotic plate 1 and the rear longitudinal orthotic plate 2 through any mounting hole 12, that is, the fixing plate 31 can be connected and fixed to any two adjacent mounting holes 12 through screws, so that the installation position of the fixing plate 31 is flexible and adjustable.

[0046] Taking the installation of the fixing plate 31 on the front longitudinal orthotic plate 1 as an example, the fixing plate 31 can be installed at any height position of the front longitudinal orthotic plate 1, or it can be installed on any side of the left and right sides of the front longitudinal orthotic plate 1. The same is true for the installation of the fixing plate 31 on the rear longitudinal orthotic plate 2. It should be noted that: two groups of transverse orthotic units 3 are installed on the lower plate 5, one of which is directly connected to the lower plate 5. Since the upper plate 6 and the lower plate 5 overlap, a strip hole 11 is opened at the lower part of the upper plate 6. The fixing plate 31 of the other group of transverse orthotic units 3 located in the middle is placed in the strip hole 11 and is detachably connected to the lower plate 5. A group of transverse orthotic units 3 is installed on the upper plate 6.

[0047] The two sides of the fixed plate 31 and the mounting hole 12 are connected by screws to achieve the installation and fixation of the fixed plate 31. On the basis of the fixed position of the fixed plate 31, the movable plate 32 can be close to or away from the fixed plate 31 to adjust the position of the movable plate 32. The movable plate 32 and the fixed plate 31 are located on the same plane, the length of the movable plate 32 is greater than that of the fixed plate 31, and the movable plate 32 is used to connect the orthopedic brace 4.

[0048] In order to adjust the position of the movable plate 32, a hand screw 13 is provided between the movable plate 32 and the fixed plate 31. Specifically, a fixed threaded barrel 14 is provided in the middle of the fixed plate 31, and the hand screw 13 is threadedly connected to the fixed threaded barrel 14. At the same time, a movable annular sleeve 15 is provided on the movable plate 32, and one end of the hand screw 13 extends into the movable annular sleeve 15 and is rotatably connected to the movable annular sleeve 15, and there is no threaded connection between the two.

[0049] When the hand screw 13 is turned, the hand screw 13 and the fixed threaded barrel 14 are threadedly connected, and then the hand screw 13 and the fixed plate 31 move relative to each other, and the hand screw 13 moves axially. The axial movement of the hand screw 13 can drive the movable plate 32 to move. Here, a limit rod 16 is also provided on the hand screw 13. The limit rod 16 adopts a fastening pin or a top screw. The limit rod 16 radially penetrates the hand screw 13, and the two ends of the limit rod 16 extend out of the hand screw 13. There are two limit rods 16, and the limit rods 16 are arranged at the two ends of the movable annular sleeve 15. In this way, when the hand screw 13 moves axially, it can drive the movable annular sleeve 15 and the movable plate 32 to move together.

[0050] The orthopedic brace 4 is a curved shell-like structure that fits the corresponding part of the human body trunk. The orthopedic brace 4 includes a brace 1 41, a brace 2 42, and a brace 3 43 that are sequentially arranged outside the human body trunk from top to bottom. The brace 1 41, the brace 2 42, and the brace 3 43 are detachably arranged between the transverse orthopedic units 3 at the upper, middle, and lower parts of the front longitudinal orthopedic plate 1 and the rear longitudinal orthopedic plate 2. Specifically, the movable plate 32 is screwed to the orthopedic brace 4. Two rows of connection holes 17 are provided on the movable plate 32. There are multiple connection holes 17 in each row. At least any two connection holes 17 can be selected and screws are passed through the connection holes 17 to connect and fix the orthopedic brace 4.

[0051] Brace 1 41 is connected to the upper chest of the human body, and is a left-right split structure, which supports the upper chest at least in the left and right directions. Brace 2 42 is connected to the waist and abdomen of the human body, and is at least two pieces, which supports the waist and abdomen at least in the left and right directions. Brace 3 43 is connected to the hip of the human body, and is arranged in a ring shape to support the hip and buttocks.

[0052] The principle of the present invention is: according to the scoliosis of the patient, a front longitudinal orthotic plate 1 and a rear longitudinal orthotic plate 2 of a fixed or telescopic structure are selected. In the present embodiment, the front longitudinal orthotic plate 1 is a telescopic structure, and the rear longitudinal orthotic plate 2 is also a telescopic structure. When worn, the front longitudinal orthotic plate 1 and the rear longitudinal orthotic plate 2 are placed on the front chest and back of the human body respectively, and the length of the front longitudinal orthotic plate 1 is adjusted according to the scoliosis situation, so that an upward and downward longitudinal force can be formed on the human body later. The transverse correction unit 3 is flexibly installed on the front longitudinal orthotic plate 1 and the rear longitudinal orthotic plate 2, respectively, so that a left and right lateral force can be formed on the human body later. Here, two groups of transverse correction units 3 are installed on the lower plate 5, and each group of transverse correction units 3 is two arranged on the left and right, and one group of transverse correction units 3 is installed on the upper plate 6.

[0053] Then, the brace 1 41, the brace 2 42 and the brace 3 43 are respectively installed between the corresponding transverse correction units 3 to ensure that the brace 1 41, the brace 2 42 and the brace 3 43 fit the corresponding parts of the human body trunk. In this way, the orthosis is worn on the human body.

[0054] After wearing, the cooperation of the front longitudinal orthosis plate 1 and the rear longitudinal orthosis plate 2 can provide a basis for the correction of the spine. The height position of the transverse orthosis unit 3 can be adjusted by the screw lifting mechanism 7, and then the position of the orthosis brace 4 can be changed, so that the orthosis brace 4 corresponds to the deformed position of the spine. During adjustment, the upper plate 6 and the lower plate 5 will move relative to each other, a group of transverse orthosis units 3 connected to the upper plate 6 will change, and the two groups of transverse orthosis units 3 connected to the lower plate 5 will change at the same time. Then, the position of the movable plate 32 is adjusted by hand-tightening the screw 13, and then the left and right positions of the orthosis brace 4 are changed, so that the orthosis brace 4 can produce a suitable corrective force on the deformed spine.

[0055] After wearing it for a period of time, the left and right positions of the orthotic brace 4 can be adjusted by means of thread adjustment according to the deformation of the spine, so as to gradually and accurately correct the deformation of the spine, so that the body can gradually adapt to the force, greatly increase the comfort of orthotic treatment, and improve the treatment effect.

[0056] The present invention can periodically stretch a certain distance during correction treatment, and the distance is appropriate to the patient's tolerance to avoid discomfort and pain caused by excessive force. Through lateral stretching and then adding longitudinal stretching, the use of threaded connection means to promote lateral and longitudinal stretching can achieve precise control effects, and can also slowly and continuously stretch, which is completely different from conventional one-time rigid orthoses.

[0057] The transverse correction unit of the present invention can be flexibly arranged on the front and rear longitudinal correction plates, and then the brace 1 41 and the brace 2 42 can be flexibly installed according to the type of scoliosis of the patient and the position of the top vertebra. The brace 1 41 and the brace 2 42 are installed with two or one, thereby forming a relative "three-point or four-point" correction force, such as Fig.10 As shown, the scoliosis deformity can be corrected in a targeted manner, and the vertical arrow indicates the direction of the longitudinal force.

[0058] Fig.10 The diagram a in the middle shows an apical vertebra. The three horizontal arrows indicate that it is corrected by three transverse correction units. The horizontal arrows are in the direction of the relative force, and the horizontal arrow in the middle points to the apical vertebra. The diagram b shows two apical vertebrae. The four horizontal arrows indicate that they are corrected by four transverse correction units. The horizontal arrows are in the direction of the relative force, and the two horizontal arrows in the middle point to the apical vertebra. Fig.10 The spinal condition shown in the figure a can be Fig.11 The orthosis shown in the figure a is used for correction; Fig.10 The spinal condition shown in the middle diagram b can be Fig.11 The orthosis shown in Figure b can be used for correction.
