Description

Technical Field

[0001] This utility model relates to the field of scoliosis correction, specifically to a back chain scoliosis adjustment brace. Background Technology

[0002] Scoliosis is a three-dimensional deformity of the spine, including abnormalities in the coronal and sagittal planes. A normal spine should appear as a straight line from the back, with symmetrical sides of the trunk. If the shoulders are uneven when viewed from the front, or the back appears uneven from side to side when viewed from behind, scoliosis should be suspected. In this case, a standing full-spine X-ray should be taken. If the X-ray shows a lateral curvature of more than 10 degrees, scoliosis can be diagnosed. Severe scoliosis can affect the growth and development of infants and adolescents, causing physical deformities. In severe cases, it can affect cardiopulmonary function and even involve the spinal cord, leading to paralysis. Mild scoliosis can be observed and followed up. Moderate scoliosis patients can try conservative treatment. If it progresses to severe scoliosis, surgical treatment is required.

[0003] Bracing is the only internationally recognized and effective conservative treatment for scoliosis. However, currently available braces are custom-made, meaning they can only be worn for one cycle and cannot adapt to changes in body shape during adolescence. Furthermore, the design and manufacturing process often relies on human experience, resulting in braces that do not conform well to the body's natural curvature. Therefore, there is a need for braces that can be adjusted in three dimensions to better conform to the body and achieve better corrective results. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a back-chain type scoliosis adjustment brace. This brace can be adjusted to different widths, heights, and curvatures to meet the correction requirements of patients at different stages.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

There are also spacing adjustment devices between the upper and lower pressure zones, which can adjust the distance between different pressure zones, thereby adjusting the height of the brace in the vertical direction and improving the stability of the brace to prevent the pressure zones from shifting vertically. The axillary pressure zone and the main pressure zone are divided and the displacement is adjustable, which further improves the adjustability of the pressure zones.

[0027] 3) The front of the brace uses a knob-type tension adjustment, which is convenient, quick, and easy to operate.

[0028] In summary, the back chain-type scoliosis adjustment brace of this utility model is lightweight, breathable, comfortable and convenient. It is adjustable and can be adjusted in multiple dimensions in terms of height, width and curvature to best adapt to the patient's body shape at different stages, so that the brace fits the human body more closely and achieves excellent correction effect.

[0053] As an optional embodiment of this utility model, in the tension adjustment component, the tension cord 203 has a "ㄈ" shape in its winding pattern, and the opening of the "ㄈ" shape can face left or right. Specifically, as... Figure 1 As shown, the knob 201 and three rope buckles 202 can be sequentially set on the second pressure zone 102, the first pressure zone 101, the third pressure zone 103, and the fourth pressure zone 104. The starting ends of the second pressure zone 102 and the first pressure zone 101 are flush, and the starting ends of the third pressure zone 103 and the fourth pressure zone 104 are flush. One end of the tension rope 203 is fixed to the knob 201, and the other end passes through two rope buckles 202 in sequence and is then fastened to the last rope buckle 202, thus forming a "ㄈ" shaped pattern.

[0054] As an optional embodiment of this utility model, in the tension adjustment component, the tension cord 203 has a "Z" shape or an inverted "Z" shape. Specifically, the knob 201 and three cord buckles 202 can be sequentially arranged on the second pressure zone 102, the first pressure zone 101, the fourth pressure zone 104, and the third pressure zone 103. The starting ends of each pressure zone at the front of the human body are, from top to bottom, the second pressure zone 102, the first pressure zone 101, the fourth pressure zone 104, and the third pressure zone 103. One end of the tension cord 203 is fixed to the knob 201, and the other end passes through two cord buckles 202 in sequence and is then fastened to the last cord buckle 202, thus forming a "Z" shape.

[0055] The back chain support 3 includes several chain links 301 and two chain heads 302. The chain links 301 are connected and locked to each other and to the chain heads 302 by a detachable hinge. The two chain heads 302 are respectively located at both ends of the back chain support 3. Each chain link 301 includes at least one set of upper connecting holes 3011, a chain plate 3012, and at least one set of lower connecting holes 3013. The lower connecting holes 3013 of two adjacent chain links 301 are connected to the upper connecting holes 3011 by a connecting component. Each chain head 302 includes a fixed connecting hole 3021 and a fixed chain plate 3022. The fixed connecting hole 3021 is connected to the adjacent upper connecting hole 3011 or lower connecting hole 3013 by a connecting component. The detachable chain structure of the back chain support 3 can increase or decrease the number of links 301, and the angle between links 301 is adjustable, thereby realizing the adjustment of the height and curvature of the back in the vertical direction of the scoliosis adjustment brace, so as to adapt to the height and spinal curvature of the patient at different stages.

[0056] Both the chain plate 3012 and the fixed chain plate 3022 are provided with screw holes 6. Several screw holes 6 are also provided laterally at the end of each pressure zone. The back chain support 3 is movably fixed to the pressure zone of the brace through the screw holes 6 and bolts. The several screw holes 6 in each pressure zone can be used to adjust the length of the back of the scoliosis adjustment brace in the horizontal direction, that is, to adjust the width of the brace, so as to adapt to the width of the patient's body shape at different stages.

[0057] As an optional embodiment of this utility model, the upper connecting hole 3011 includes one set of connecting holes, and the lower connecting hole 3013 includes two sets of connecting holes; the top of the chain plate 3012 is provided with a groove 3014, and the outer side is provided with a locking screw hole 7, which communicates with but does not penetrate the groove 3014; the connecting assembly includes a connector 3032 and a displacement member 3031, wherein the connector 3032 includes two sleeves 30321 connected in parallel and two shafts B30322, wherein When a shaft B30322 is connected to the upper connecting hole 3011 of an adjacent chain link 301, it is in a locked state, meaning it cannot rotate within the hole; the displacement member 3031 includes a plate 30311 and a shaft A30312 fixed to the top of the plate 30311, and the plate 30311 and the groove 3014 are compatible; the top of the chain head 302 located at the bottom of the back chain support 3 is provided with a groove 3014, and the outer side is provided with a locking screw hole 7, which is connected to but does not penetrate the groove 3014.

[0058] Specifically, such as Figure 5-10 As shown, the first form of the back chain support 3 is as follows: Figure 5 As shown, the relatively smooth side is the inner side of the back chain support 3, and the side with the connecting structure is the outer side.

[0059] In this situation, link 301 is as follows: Figure 6 As shown, the upper connecting hole 3011 has one set of connecting holes, and the lower connecting hole 3013 has two sets of connecting holes. Each set of connecting holes includes two connecting holes, which are distributed on the left and right sides of the top or bottom of the chain plate 3012. The two sets of connecting holes of the lower connecting hole 3013 are arranged side by side in the horizontal direction. Furthermore, the upper connecting hole 3011, the lower connecting hole 3013, and the fixed connecting hole 3021 in the first form can be open on one side, made of elastic material, so that the shaft can be inserted into the connecting hole through the bayonet 8.

[0060] like Figure 7 As shown, the top of the chain plate 3012 is provided with a groove 3014, such as... Figure 9 The insert plate 30311 in the displacement member 3031 shown can be fully inserted into the groove 3014, and the shaft A30312 fixed to the top of the insert plate 30311 can be embedded in a set of connecting holes inside the lower connecting hole 3013 of the previous adjacent link 301. Figure 8The connector 3032 shown connects to the upper connecting hole 3011 of the next adjacent link 301 and a set of connecting holes outside the lower connecting hole 3013 of the previous adjacent link 301. The shaft B30322 connected to the upper connecting hole 3011 of the connector 3032 should not be able to rotate in the connecting hole. The upper connecting hole 3011 can be further closed by external force, or locking elements can be provided on both sides of the shaft B30322. The locking elements can be nuts, so that the shaft B30322 cannot rotate in the hole.

[0061] The shaft B30322 connected to the upper connecting hole 3011 can also be a screw. The upper connecting hole 3011 does not have a bayonet 8 and has an internal thread. The shaft B30322 can be screwed into the upper connecting hole 3011.

[0062] When the angle of each link 301 is manually adjusted, the shaft B30322 of the connector 3032 connected to the lower connecting hole 3013 of the previous adjacent link 301 can rotate, and the insert plate 30311 can move horizontally within the groove 3014 to adjust the volume of the insert plate 30311 within the groove 3014, thereby realizing the adjustment of the angle of the link 301 and adapting to the spinal curvature of the patient at different stages.

[0063] like Figure 6 As shown, the outer side of the chain plate 3012 is also provided with a locking screw hole 7. The locking screw hole 7 is connected to but does not penetrate the groove 3014. The bolt passes through the locking screw hole 7 to lock the insert plate 30311 to achieve the purpose of angle fixation. The screw hole 6 is located below the bottom of the groove 3014. The chain link 301 can be fixed on the pressure area through the screw hole 6.

[0064] like Figure 10 As shown, A is the top chain head 302, and B is the bottom chain head 302. The top chain head 302 has a fixing connection hole 3021 that is the same as the lower connection hole 3013 of the chain link 301, and its fixing chain plate 3022 has a screw hole 6. The bottom chain head 302, compared to the chain link 301, lacks the lower connection hole 3013.

[0065] As an optional embodiment of this utility model, the inner ring surfaces of the upper connecting hole 3011, the lower connecting hole 3013 and the fixed connecting hole 3021 are set in a toothed shape, and the connecting component is a pin with a toothed surface, and the connecting hole and the pin are engaged by gear teeth.

[0066] Specifically, such as Figure 11-14 As shown, the second form of the back chain support 3 is as follows: Figure 11 As shown, the relatively smooth side is the inner side of the back chain support 3, and the side with the connecting structure is the outer side.

[0067] In this situation, link 301 is as follows: Figure 12 As shown, the upper connecting hole 3011 is a group of connecting holes distributed on the left and right sides of the top of the chain plate 3012, and the lower connecting hole 3013 is a connecting hole distributed at the bottom of the chain plate 3012. The lower connecting hole 3013 fits precisely between the upper connecting holes 3011. The inner ring surfaces of the upper connecting hole 3011 and the lower connecting hole 3013 are set in a tooth shape, and the connecting assembly is as follows. Figure 14 The surface shown is set as a toothed pin, and the connecting hole and the pin are engaged by gear teeth. When the curvature of the back chain support 3 needs to be adjusted, the pin is removed, and then the connected chain link 301 is rotated coaxially to adjust the angle. Then the pin is locked, which can realize the adjustment of the angle of the chain link 301, so as to adapt to the spinal curvature of the patient at different stages.

[0068] Furthermore, such as Figure 14 As shown, the inside of the pin is hollow, which can be a pin hole or a screw hole for locking fasteners.

[0069] like Figure 13 As shown, A is the top chain head 302, and B is the bottom chain head 302. The top chain head 302 has a fixing connection hole 3021 that is the same as the lower connection hole 3013 of the chain link 301, and its fixing chain plate 3022 is provided with a screw hole 6; the bottom chain head 302 has a fixing connection hole 3021 that is the same as the upper connection hole 3011 of the chain link 301, and its fixing chain plate 3022 is provided with a screw hole 6.

[0070] As an optional embodiment of this utility model, the upper connecting hole 3011, the lower connecting hole 3013 and the fixed connecting hole 3021 are pin holes or screw holes, and the sides of each pair that are in contact with each other are set as teeth. The pin holes that are in contact with each other are engaged by gear teeth. The connecting component is a pin or bolt.

[0071] Specifically, such as Figure 15-17 As shown, the third form of the back chain support 3 is as follows: Figure 15 As shown, the relatively smooth side is the inner side of the back chain support 3, and the side with the connecting structure is the outer side.

[0072] In this situation, link 301 is as follows: Figure 16 As shown, the upper connecting hole 3011 is a screw hole, and the lower connecting hole 3013 is a screw hole. The two screw holes are respectively distributed on the left and right sides of the top and bottom ends of the chain plate 3012. The contact surfaces between the upper connecting hole 3011 and the lower connecting hole 3013 of the connecting link 301 are toothed, so that they mesh through the teeth when in contact, and are then locked by bolts. When the curvature needs to be adjusted, the bolts are removed, and the angle of the chain link 301 is adjusted to realize the adjustment of the curvature of the back chain support 3, so as to adapt to the spinal curvature of the patient at different stages.

[0073] like Figure 17 As shown, the chain head 302 has a fixed connection hole 3021 on only one end, and the fixed chain plate 3022 has a screw hole 6.

[0074] Several pressure zones located in the same vertical direction are connected at their starting ends by a spacing adjustment component 5, which can be a telescopic rod or a perforated plate. Specifically, for example... Figure 1 As shown, the starting ends of the first pressure zone 101 and the third pressure zone 103, and the starting ends of the second pressure zone 102 and the fourth pressure zone 104 are connected by telescopic rods. The telescopic rods allow for free adjustment of the distance between the connected pressure zones, thus adapting to the patient's varying body height at different times and improving the comfort of the brace. The telescopic rods can also be replaced with perforated plates, positioned via holes, and fixed with bolts, achieving the same adjustment purpose.

[0075] Each pressure zone has a edging 4 at its edge. Specifically, such as... Figure 3 , 4 As shown, the first pressure zone 101 has a edging 4 near the armpit and the upper side near the chest; the third pressure zone 103 has a edging 4 near the lower side of the abdomen; the second pressure zone 102 has a edging 4 near the armpit; the second pressure zone 102 may also have a edging 4 near the upper side of the chest; and the fourth pressure zone 104 may also have a edging 4 near the lower side of the abdomen (not shown in the figure). Furthermore, the edging can be made of elastic or soft material to make the patient more comfortable when in contact with the pressure area.

[0076] The pressure zones near the armpit include main pressure zones 1011 and 1021 and axillary pressure zones 1012 and 1022. These zones are connected by a spacing adjustment component 5, which can be a telescopic rod or a perforated plate. Adjusting the axillary pressure zones 1012 and 1022 upwards increases the pressure area, while adjusting them downwards increases comfort. Specifically, for example... Figure 3 , 4 As shown, the main pressure zones 1011 and 1021 and the underarm pressure zones 1012 and 1022 are connected by a telescopic rod, which allows for free adjustment of the distance between the connected pressure zones. The telescopic rod can also be replaced with a perforated plate, positioned via holes, and fixed with bolts, achieving the same adjustment purpose.

[0077] Furthermore, the axillary pressure zones 1012 and 1022 may be provided with a edging 4 near the edge of the armpit, which may extend to the inside and bottom of the axillary pressure zones 1012 and 1022. The edging may be made of elastic or soft material to make the patient more comfortable when in contact with the pressure area.

[0078] At least one pressure zone has several vent holes, forming a 3D grid structure.
