Description

Technical Field

[0001] The present invention belongs to the field of medical equipment, in particular to a spinal correction component and correction device. Background Art

[0002] Scoliosis, also known as scoliosis, typically includes C-shaped and S-shaped curves. Currently, scoliosis requires correction with a corrective device. Commonly used corrective devices include wearable braces, which require long-term wear. These devices struggle to maintain stable pressure, are difficult to adjust based on spinal deformation, and offer limited visual monitoring of the corrective effect, resulting in poor results.

[0003] The invention patent with application number CN201610269624.2 discloses a fully automatic three-dimensional scoliosis corrector that can automatically correct the spine. The invention patent with application number CN202111422915.8 discloses a visual scoliosis correction treatment bed based on cloud computing control and its use method. The pelvic positioning device and axial traction device are used to position the patient on the bed, creating conditions for subsequent spinal correction; the patient's spine is scanned by an X-ray scanning unit to obtain a spinal image so that the control unit can obtain correction parameter information, thereby accurately controlling the correction device and axial traction device to perform automated correction operations on the patient's spine. The correction accuracy is high, the correction effect is greatly improved, and the patient's recovery time is shortened; when combined with a display, the patient can visualize the changes in spinal correction in real time.

[0004] The correction principles of various existing correction devices are as follows: Figure 1 As shown, pressure or thrust F is applied to the human body surface corresponding to the vertices of the scoliosis of the spine 100. Under the action of the pressure or thrust F, the curvature of the scoliosis of the spine 100 gradually decreases and eventually returns to the standard shape. When correcting with existing correction devices, the direction and point of action of the pressure or thrust F applied to each scoliosis of the spine 100 are fixed. During the process of spinal reduction, secondary scoliosis may occur, for example, Figure 1 When the spine 100 shown is corrected by the force F, the following may occur: Figure 2 Therefore, existing correction devices have the risk of secondary scoliosis.

DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the accompanying drawings and examples.

[0034] The spinal correction component of the present invention, such as Figure 3 As shown, including:

[0035] The main thrust mechanism 1 is used to apply a main thrust perpendicular to the direction of human height to the body surface position corresponding to the top of the scoliosis.

[0036] The upper auxiliary thrust mechanism 2 is used to apply an upper auxiliary thrust inclined downward to the body surface position corresponding to the upper segment of the scoliosis.

[0037] The lower auxiliary thrust mechanism 3 is used to apply an upward inclined lower auxiliary thrust to the body surface position corresponding to the lower segment of the scoliosis.

[0038] like Figure 4 As shown, when the spinal correction assembly of the present invention is used to correct the scoliosis segment, the main thrust mechanism 1 applies a main thrust F1 perpendicular to the direction of human height to the body surface position corresponding to the top of the scoliosis, the upper auxiliary thrust mechanism 2 applies an upper auxiliary thrust F2 inclined downward to the body surface position corresponding to the upper segment of the scoliosis, and the lower auxiliary thrust mechanism 3 applies a lower auxiliary thrust F3 inclined upward to the body surface position corresponding to the lower segment of the scoliosis.

[0039] In the present invention, the scoliosis section is divided into three parts: the top, the upper scoliosis section, and the lower scoliosis section. The upper and lower scoliosis sections are located on either side of the top. The upper and lower directions are based on a standing human body, for example, with the head and neck above the waist and abdomen.

[0040] During correction, the main thrust mechanism 1, the upper auxiliary thrust mechanism 2 and the lower auxiliary thrust mechanism 3 contact one side of the human trunk, providing thrust to the human trunk, and the thrust is transmitted to the scoliosis through the human body.

[0041] The main thrust F1 provides the primary corrective force, gradually reducing the scoliotic curve. The upper and lower auxiliary thrusts F2 and F3 assist in correcting the curve. Their directions can align with the radial direction of the upper and lower scoliotic segments. These forces increase the force-bearing area of the entire scoliotic segment during correction, improving force uniformity and effectively preventing secondary curvature caused by the main thrust F1, thereby ensuring effective correction.

[0042] During the correction process, the curvature of the scoliotic segment will gradually decrease. Therefore, the direction of the upper auxiliary thrust F2 and the lower auxiliary thrust F3 should be adjusted according to the curvature of the upper and lower scoliotic segments to ensure the correction effect. In order to make the direction of the upper auxiliary thrust F2 and the lower auxiliary thrust F3 compatible with the dimensions of the upper and lower scoliotic segments, the upper auxiliary thrust mechanism 2 and the lower auxiliary thrust mechanism 3 are both connected to an angle adjustment mechanism. The angle adjustment mechanism can adjust the angle of the upper auxiliary thrust mechanism 2 and the lower auxiliary thrust mechanism 3, and thus adjust the thrust direction provided by the upper auxiliary thrust mechanism 2 and the lower auxiliary thrust mechanism 3.

[0043] like Figure 5 、 Figure 6 As shown, the main thrust mechanism 1 includes a main thrust member 11, which is connected to a main thrust block 12. The side of the main thrust block 12 away from the main thrust member 11 is an arcuate surface. The main thrust member 11 can be a pneumatic cylinder, a hydraulic cylinder, or other device. The arcuate surface can better conform to the human torso and evenly transmit thrust to one side of the torso. The main thrust member 11 can push the main thrust block 12 to move, so that the arcuate surface of the main thrust block 12 contacts the left or right side of the human torso and provides appropriate thrust.

[0044] Both the upper auxiliary thrust mechanism 2 and the lower auxiliary thrust mechanism 3 include an auxiliary thrust power member 21, which is connected to an auxiliary thrust block 22. The side of the auxiliary thrust block 22 away from the auxiliary thrust power member 21 is an arcuate surface. The auxiliary thrust power member 21 can be a device such as a pneumatic cylinder or a hydraulic cylinder, which can push the auxiliary thrust block 22 to move so that the auxiliary thrust block 22 contacts the left or right side of the human torso and provides auxiliary thrust.

[0045] In order to facilitate monitoring of the magnitudes of the main thrust F1 , the upper auxiliary thrust F2 and the lower auxiliary thrust F3 , pressure sensors may be provided between the main thrust block 12 and the main thrust power member 11 , and between the auxiliary thrust block 22 and the auxiliary thrust power member 21 .

[0046] The main thrust block 12 and the auxiliary thrust block 22 can be a whole block, but because the surface shape of the human body is usually irregular, the curved surface of the main thrust block 12 and the auxiliary thrust block 22 is difficult to evenly fit the human body. In order to make the auxiliary thrust block 22 and the main thrust block 12 fully fit the human body, the main thrust block 12 and the auxiliary thrust block 22 each include a fixed block 121 and a plurality of adjustment blocks 122, one side of the fixed block 121 is fixedly mounted on the main thrust power member 11 or the auxiliary thrust power member 21, and the top and bottom of the other side of the fixed block 121 are respectively provided with an upper positioning plate 123 and a lower positioning plate 124, the upper end of each adjustment block 122 is slidably matched with the upper positioning plate 123, and the lower end of each adjustment block 122 is slidably matched with the lower positioning plate 124, and each adjustment block 122 is connected to the fixed block 121 by a spring 125.

[0047] An upper slide groove with a rectangular cross-section can be set on the lower surface of the upper positioning plate 123, and a lower slide groove with a rectangular cross-section can be set on the upper surface of the lower positioning plate 124. The upper end of the adjustment block 122 is located in the upper slide groove and slides with the upper slide groove, and the lower end of the adjustment block 122 is located in the lower slide groove and slides with the lower slide groove.

[0048] The thrust provided by the main thrust power member 11 and the auxiliary thrust power member 21 is first transmitted to the fixed block 121, and then transmitted to each adjustment block 122 through the spring 125, and each adjustment block 122 then transmits the thrust to the human body. Since the adjustment block 122 can slide, the position of each adjustment block 122 is not fixed, and can automatically adjust the position as the surface of the human body rises and falls, ensuring that each adjustment block 122 can fit closely to the surface of the human body. In addition, when the adjustment block 122 contacts the human body, the spring 125 can play a buffering role. The adjustment block 122 can be a rigid block such as a metal block. In order to improve comfort, an elastic pad can be set on the curved surface of the adjustment block 122 that contacts the human body.

[0049] The angle adjustment mechanism can be a telescopic mechanism, such as a pneumatic cylinder or linear motor, with the upper auxiliary thrust mechanism 2 and the lower auxiliary thrust mechanism 3 being hingedly mounted. The telescopic mechanism is hingedly connected to the upper auxiliary thrust mechanism 2 and the lower auxiliary thrust mechanism 3. When the telescopic mechanism is extended or retracted, it drives the upper auxiliary thrust mechanism 2 and the lower auxiliary thrust mechanism 3 to rotate, thereby achieving angle adjustment. However, this method makes it difficult to precisely control the rotation angle of the upper auxiliary thrust mechanism 2 and the lower auxiliary thrust mechanism 3.

[0050] To achieve precise adjustment, the angle adjustment mechanism includes a servo motor 23. Both the upper auxiliary thrust mechanism 2 and the lower auxiliary thrust mechanism 3 are fixedly mounted on a positioning block 24. A drive shaft 25 is provided at the upper or lower end of the positioning block 24. The servo motor 23 is connected to the drive shaft 25 via a reduction gear set. The servo motor 23 drives the drive shaft 25 through the reduction gear set, which in turn drives the positioning block 24, which in turn drives the entire upper auxiliary thrust mechanism 2 or lower auxiliary thrust mechanism 3. The servo motor 23 can precisely control the rotation angle. After being reduced by the reduction gear set, it can drive the upper auxiliary thrust mechanism 2 or lower auxiliary thrust mechanism 3 to rotate stably, and the rotation angle is controllable.

[0051] The main thrust mechanism 1, the upper auxiliary thrust mechanism 2, and the lower auxiliary thrust mechanism 3 can be installed on a base, which can be a solid metal plate. The transmission shafts 25 of the upper auxiliary thrust mechanism 2 and the lower auxiliary thrust mechanism 3 are installed on the base through bearings, and the main thrust mechanism 1 is installed between the upper auxiliary thrust mechanism 2 and the lower auxiliary thrust mechanism 3. In order to adjust the position of the main thrust mechanism 1, the upper auxiliary thrust mechanism 2, and the lower auxiliary thrust mechanism 3, three sliders can be provided on the base. The three sliders slide with the base. The main thrust mechanism 1, the upper auxiliary thrust mechanism 2, and the lower auxiliary thrust mechanism 3 are respectively installed on a slider. The positions of the main thrust mechanism 1, the upper auxiliary thrust mechanism 2, and the lower auxiliary thrust mechanism 3 can be adjusted by sliding the sliders. In addition, three bases can also be provided, with the main thrust mechanism 1, the upper auxiliary thrust mechanism 2, and the lower auxiliary thrust mechanism 3 respectively installed on a base.

[0052] The correction device of the present invention, such as Figures 7 to 10 As shown, it includes a bracket 5 and a shoulder positioning mechanism 6 and a waist-hip positioning mechanism 7 arranged on the bracket 5. A correction space is set between the shoulder positioning mechanism 6 and the waist-hip positioning mechanism 7, and a torso supporting mechanism is set in the correction space.

[0053] The shoulder positioning mechanism 6 is used to position the patient's shoulders, and the waist and hip positioning mechanism 7 is used to position the patient's waist and hips. After the patient's shoulders and waist and hips are positioned, the patient's trunk can be kept stable to facilitate spinal correction. The trunk support mechanism can be a horizontal support plate or multiple horizontal support rollers.

[0054] There are two sides of the correction space. Figure 3 、 Figure 5 and Figure 6 Spinal correction components shown.

[0055] The spinal correction assembly is mounted on bracket 5. Scoliosis is typically C-shaped or S-shaped. C-shaped scoliosis is characterized by a single-sided curve, requiring only one corrective force. S-shaped scoliosis, however, has two lateral curves, one on the left and one on the right, requiring simultaneous corrective force. The present invention incorporates a spinal correction assembly on each side of the correction space, addressing both C-shaped and S-shaped scoliosis.

[0056] Since the scoliosis position of different patients is different, in order to facilitate the adjustment of the positions of the main thrust mechanism 1, the upper auxiliary thrust mechanism 2 and the lower auxiliary thrust mechanism 3 according to the position and size of the patient's scoliosis, so that the main thrust mechanism 1 is aligned with the top of the scoliosis, the upper auxiliary thrust mechanism 2 is aligned with the upper section of the scoliosis, and the lower auxiliary thrust mechanism 3 is aligned with the lower section of the scoliosis, the present invention is provided with a first mounting seat 41, a second mounting seat 42 and a third mounting seat 43 on both sides of the correction space, and the first mounting seat 41, the second mounting seat 42 and the third mounting seat 43 are arranged in sequence along the direction from the shoulder positioning mechanism 6 to the waist and hip positioning mechanism 7, the first mounting seat 41, the second mounting seat 42 and the third mounting seat 43 are all slidably matched with the bracket 5, and the first mounting seat 41, the second mounting seat 42 and the third mounting seat 43 are all connected with a position adjustment mechanism; the main thrust mechanism 1, the upper auxiliary thrust mechanism 2 and the lower auxiliary thrust mechanism 3 are respectively installed on the first mounting seat 41, the second mounting seat 42 and the third mounting seat 43.

[0057] The first, second, and third mounting bases 41, 42, and 43 are capable of sliding under the guidance of a position adjustment mechanism, with the sliding direction being aligned with the height of the person being corrected. The position adjustment mechanism can adjust the positions of the first, second, and third mounting bases 41, 42, and 43, respectively, allowing the first, second, and third mounting bases 41, 42, and 43 to each be positioned in a variety of positions.

[0058] The position adjustment mechanism can be a pneumatic cylinder, a hydraulic cylinder, or other device that can drive the first mounting seat 41, the second mounting seat 42, and the third mounting seat 43 to slide by telescoping. However, pneumatic cylinders and hydraulic cylinders themselves require a certain length, making installation inconvenient and limiting the adjustment distance. As a preferred embodiment, the position adjustment mechanism includes a rack 44 fixedly mounted on the bracket 5. Adjustment motors 45 are fixedly mounted on the first mounting seat 41, the second mounting seat 42, and the third mounting seat 43. The main shaft of each adjustment motor 45 is provided with an adjustment gear 46, and each adjustment gear 46 meshes with the rack.

[0059] When the adjustment motor 45 rotates, it drives the adjustment gear 46 to rotate. Under the action of the rack 44, the adjustment gear 46 can move linearly, thereby driving the first mounting seat 41, the second mounting seat 42, or the third mounting seat 43 to move as a whole. Each adjustment motor 45 can operate independently to achieve independent adjustment of the position of the first mounting seat 41, the second mounting seat 42, or the third mounting seat 43. The three adjustment motors 45 share a single rack 44, simplifying the device structure.

[0060] The shoulder positioning mechanism 6 and the waist and hip positioning mechanism 7 can adopt existing technology, using clamping positioning plates on the left and right sides, respectively, which are connected to a power mechanism such as a cylinder or hydraulic cylinder. The power mechanism pushes the clamping positioning plates to move, thereby clamping the clamping positioning plates to the waist and hips or shoulders of the human body. This method has poor positioning stability, and when the body shapes of different patients vary greatly, different sizes of clamping positioning plates are required, which is inconvenient to use.

[0061] As a preferred embodiment of the present invention, the shoulder positioning mechanism 6 includes a fixed support plate 61, which is fixedly mounted on the bracket 5 and is in a horizontal state. A left shoulder positioning mechanism and a right shoulder positioning mechanism are provided on the fixed support plate 61, and the structures of the left shoulder positioning mechanism and the right shoulder positioning mechanism are the same. Specifically, the left shoulder positioning mechanism and the right shoulder positioning mechanism both include a first positioning belt 62, a clamping block 63 and a first reeling and unwinding mechanism 64, and the first positioning belt 62 adopts a flexible belt with high tensile strength. The clamping block 63 is slidably matched with the fixed support plate 61, and a dovetail-shaped slide groove can be provided on the upper surface of the fixed support plate 61, and a dovetail-shaped slider is provided at the bottom of the clamping block 63. The slider is located in the slide groove and slidably matched with the slide groove, and the length direction of the slide groove is consistent with the height direction of the human body during correction.

[0062] A first clamping surface is provided on one side of the clamping block 63, and the shape of the first clamping surface is adapted to the shape of the human shoulder. A first guide shaft 65 is provided on the other side. A first through groove is provided at the bottom of the clamping block 63 extending from the first clamping surface to the other side. One end of the first positioning belt 62 is fixed on the fixed support plate 61, and the other end is connected to the first rewinding mechanism 64 after passing through the first through groove and the first guide shaft 65 in sequence. The first rewinding mechanism 64 is located above the connection between the first positioning belt 62 and the fixed support plate 61.

[0063] When positioning the patient's shoulders, the patient lies face up with the head and neck positioned on the fixed support plate 61. The clamping blocks 63 of the left and right shoulder positioning mechanisms are positioned on both sides of the neck. The patient's hands are passed under the first positioning belt 62 so that the shoulders are positioned between the clamping blocks 63 and the fixed end of the first positioning belt 62. The first positioning belt 62 is then wound up using the first reeling and unwinding mechanism 64. When the first positioning belt 62 is wound up, a force is applied to the first guide shaft 65, pushing the clamping blocks 63 to slide toward the patient's shoulders until the clamping blocks 63 are in close contact with the patient's shoulders. After tightening the first positioning belt 62, the patient's shoulders are pressed against the fixed support plate 61 by the first positioning belt 62, and the clamping blocks 63 are in close contact with the patient's shoulders, thereby stably positioning the patient's shoulders.

[0064] The present invention can position the shoulders of patients of different body shapes, and since the first positioning belt 62 is used to tie and fix the patient's shoulders, the clamping block 63 only plays an auxiliary positioning role. Therefore, a universal clamping block 63 can be used, and there is no need to replace positioning mechanisms of different sizes according to the patient's body shape, which makes operation more convenient.

[0065] The bracket 5 is provided with a movable support plate 71 that slidably engages with the bracket 5. The movable support plate 71 can slide on the bracket 5 in a direction aligned with the patient's height during correction. The movable support plate 71 is connected to a drive mechanism 72. The drive mechanism 72 can drive the movable support plate 71 to slide, thereby adjusting the distance between the movable support plate 71 and the fixed support plate 61 to facilitate positioning of patients of different heights. The drive mechanism 72 can be a hydraulic cylinder, a pneumatic cylinder, or a motor-driven screw mechanism.

[0066] When the handle 72 is in the unlock position, the second stop 77 is in the unlock position, and the lock 71 is in the unlock position, and the lock 71 is in the unlock position, and the lock 71 is in the unlock position.

[0067] During positioning, the patient lies flat on the movable support plate 71, with the patient's legs passing under the second positioning belt 73, so that the support shaft 79 is located under the patient's crotch, the patient's left thigh is located between the support shaft 79 and the left clamping block 74, and the patient's right thigh is located between the support shaft 79 and the left clamping block 74. Then, the second reeling and unreeling mechanism 76 can be used to simultaneously reel in both ends of the second positioning belt 73. When the second positioning belt 73 is reeled in, a force is applied to the third guide shaft 78 and the second guide shaft 77, pushing the left clamping block 74 and the right clamping block 75 toward the patient, so that the left clamping block 74 and the right clamping block 75 respectively clamp the patient's left and right hips. After the second positioning belt 73 is tightened, the second positioning belt 73 can bind and secure the patient's left and right thigh roots to the movable support plate 71. At the same time, the left clamping block 74 and the right clamping block 75 play a role in auxiliary positioning, ensuring effective positioning of the patient.

[0068] In the present invention, since the left and right clamping blocks 74 and 75 only serve to assist in positioning, patients of all body shapes can use universal components, eliminating the need to replace multiple sizes of left and right clamping blocks 74 and 75, thereby improving ease of use. Furthermore, only one second retracting and unreeling mechanism 76 is required to simultaneously retract and unreel both ends of the second positioning belt 73, reducing the number of power devices and lowering equipment costs.

[0069] The first reeling and unreeling mechanism 64 and the second reeling and unreeling mechanism 76 can be small winches fixedly mounted on the bracket 5 .

[0070] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
