(2) Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98
The disclosure and prior art relates to back brace devices and more particularly pertains to a new back brace device for adjusting curvature of the device for supporting a desired shape of the spine.
An embodiment of the disclosure meets the needs presented above by generally comprising a belt for extending around a torso of a human. The belt has a front closure and is positionable in a closed loop. A support panel is coupled to the belt such that the support panel projects from an inner surface of the closed loop towards a center of the closed loop. The support panel abuts the torso and has a curved surface facing the center of the closed loop. A curvature of the curved surface extending between lateral edges of the belt is adjustable.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A circumference of the closed loop 26 may be varied by adjustment of the front closure 24 or the circumference of the closed loop 26 may be set through adjustment of one of more other conventional adjustment mechanisms such that the front closure does not adjust to change the circumference of the closed loop 26. In the latter situation, the belt 12 may be provided in a length corresponding generally to torso size and fitted by adjustment of the other adjustment mechanisms which may then be set to prevent unwanted variation in the length of the belt 12 after fitting. It is contemplated that the front closure 24 may still provide minor adjustment to the circumference if desired after fitting while still allowing the fitting to establish desired positioning of the elements of the device 10 on the torso 22.
A curvature of the curved surface 34 extends between the lateral edges 18,20 of the support panel 32 is adjustable. The curvature may correspond to a desired formula or pattern such as a formula for correction of lumbar lordosis dependent on pelvic incidence. This exemplary formula and correction of lumbar lordosis is described in issued U.S. Pat. No. 9,237,956. The curvature of the curved surface 34 of the support panel 32 is adjustable such that the curvature is configured for adjustment corresponding to lumbar lordosis between 0 and 90 degrees of curvature. Adjustment may be achieved through use of an adjustment line 38 engaging the support panel 32 such that pulling on the adjustment line 38 adjusts the curvature of the curved surface 34 of the support panel 32. The adjustment line 38 may be linked to an array of pulleys, loops, channels, or the like to provide mechanical advantage in providing an adjustment force to the support panel 32. Use of such mechanisms is conventionally known in braces such as found in issued U.S. Pat. No. 6,602,214 disclosing specifically a pulley like system for laterally tightening a brace using a single pull line. A free end 40 of the adjustment line 38 is engageable to the belt 12 wherein the free end 40 of the adjustment line 38 is coupled to the belt 12. The free end 40 of the adjustment line 38 is coupled to the belt 12 in a static position wherein tension in the adjustment line 38 maintains the curvature of the curved surface 34 of the support panel 32. Each of a plurality of marks 42 is positioned on the outer surface 30 of the closed loop 26. The marks 42 are spaced along a length of the belt 12 wherein positioning of the free end 42, which for purposes of this application may effectively be the position of a fastener used to secure the adjustment line 38 to the belt 12, adjacent or corresponding to a selected one of the marks 42 corresponds to a degree of adjustment of the curvature of the curved surface 34. Thus, once fitted, the curvature of the curved surface is consistently adjustable to a desired degree of lordosis by securement of the free end 40 to corresponding to the appropriate corresponding mark 42.
Control of the adjustment of the curvature of the curved surface 24 of the support panel 32 may be achieved in various ways including but not limited to the following described mechanisms. In an embodiment of the invention, each of a plurality of bend lines 44 extends laterally across the support panel 32. The bend lines 44 are spaced apart between an upper end 46 and a lower end 48 of the support panel 32 wherein adjustment of a distance between the upper end 46 and the lower end 48 of the support panel 32 provided by pulling of the adjustment line 38 results in bending of the support panel 32 at the bend lines 44. Thus, the positioning of the bend lines 44 determines alteration of the curvature of the curved surface 34 of the support panel 32.
Alternatively as shown in
The support panel 32 may be coupled directly to the belt 12. Alternatively, the support panel 32 may be coupled to a backing panel 50 which is removably couplable to the belt 12 in a conventional manner using fasteners such as snaps, hook and loop fasteners, or the like. The backing panel 50 is typically stiff and secured rigidly relative to the belt providing additional bracing to a back of the user. The backing panel 50 has an uppermost edge 52 and a bottommost edge 54. A length between the bottommost edge 54 and the topmost edge 52 can range between 7.0 and 40.0 inches. The backing panel 50 may be one of a plurality of backing panels 50 having varied lengths within the above range such that support of the back of the user is customizable to cover a desired portion of the user's back. For a small brace the range may be between 7.0 and 8.5 inches, an LSO brace may be up to 14.5 inches, and a TLSO brace may be up to 40.0 inches. The support panel 32 is coupled to the backing panel 50 closer to the bottommost edge 54 than the topmost edge 52 and the curved surface 34 of the support panel 32 has a length and is positioned on the belt 12 or backing panel 50 such that the support panel 32 is configured for positional alignment extending between a L1 vertebral body and a S1 vertebral body. Thus, the device 10 is designed to be adjustable to provide lordosis support complementary to a desired lordosis for the back such as is exemplified in U.S. Pat. No. 9,237,956.
Adjustment of the curvature of the curved surface 34 is generally achieved through application of tension to draw the upper end 46 of the support panel 32 and the lower end 48 of the support panel 32 together. This may be achieved in a variety of ways including the lower end 48 being coupled to the belt 12, directly or through use of the backing panel 50, in a fixed position. However, the lower end 48 may be pivotal at the fixed position to facilitate formation of the desired curvature. The upper end 46 of the support panel 32 is slidably coupled to the belt 12, again either directly or through use of the backing panel 50. The curvature of the curved surface 34 of the support panel 32 is adjusted by sliding of the upper end 46 of the support panel 32 relative to the belt 12. Each of a plurality of slots 56 may extend through the support panel 32. Each of the slots 56 is parallel to a length of the support panel 32. Generally, each of a plurality of fasteners 58 is coupled to the belt 12, either directly or by virtue of being coupled directly to the backing panel 50. Each of the fasteners 58 extends through an associated one of the slots 56 wherein the fastener 58 is slidable within the associated one of the slots 56. Thus, manipulation of the adjustment line 38 translates to linear application of tension in the support panel 32 to drive adjustment of the curvature of the curved surface 34 of the support panel 32. The plurality of slots 56 may be an upper pair 60 of slots 56 positioned adjacent to the upper end 46 of the support panel 32, a lower pair 62 of slots 56 positioned adjacent to the lower end 48 of the support panel 32, or a combination of the upper pair 60 and lower pair 62 may be simultaneously employed with or without additional structure to fix the position of the support panel 32 relative to the belt 12 or backing panel 50 depending on whether it is desired for the support panel 32 as a whole to have a set curvature but be able to move relative to the belt 12 or backing panel 50.
Alternatively, as shown in
In another embodiment as shown in
The support panel 32 may also be provided with a curved medial portion 76 and end portions 78 extending from the curved medial portion 76 to facilitate coupling to the belt 12 or backing panel 50. In such an embodiment, the distance between a top edge 80 and bottom edge 82 of the curved medial portion 76 provides the effective curvature to be adjusted. The curved medial portion 76 may be further defined between pivotal connections 84 facilitating adjustment of the curvature while the end portions 78 remain adjacent to the belt 12.
The device 10 may be provided with a pair of support panels 32. Each of the support panels 32 is coupled to the belt 12 such that the support panel 32 projects from the inner surface 28 of the closed loop 26 towards a center of the closed loop 26 wherein each support panel 32 is configured for abutting the torso. The pair of support panels 32 is laterally aligned and spaced apart such that the curvature of the curved surfaces 34 of the support panels 32 defines a gap 70 between the support panels 32. Thus, the pair of support panels 32 is configured for spacing the belt 12 from direct contact with the user along the spine by aligning the gap 70 with the spine while the belt 12 is secured around the torso 22. An alignment bar 72 may be coupled to and extend between the pair of support panels 32 inhibiting independent movement of the support panels 32 and therefore promoting similar curvature in the curved surfaces 34 of the support panels 32. Further, a single adjustment line 74 engaging both support panels 32 may be utilized for a two support panel configuration. Pulling on the single adjustment line 74 shortens the distance between the upper end 46 and the lower end 48 of each of the support panels 32.
Alternatively, each of a pair of adjustment lines 76 is engaged to a respective one of the support panels 32 wherein a distance between the upper end 46 and the lower end 48 of each of the support panels 32 is separately adjustable by manipulation of the adjustment lines 76. Similar to the above description, each support panel 32 may be coupled directly to the belt 12 or to the backing panel 50.
The specific shape of the curvature of the support panel may correspond to a desired or preferred formula to be complementary to desired shape of the spine. By way of example, a cumulative angle between each of multiple pairs of vertebral bodies may be supported relative to pre-determined reference lines determined from measurements of pelvic incidence. Alternatively, other body references may be utilized to determine alternative formulations to achieve or determine the desired shape for the curvature of the curved surface 34. Additional factors may include pelvic tilt and C7 plumb line. Desired angles between each pair of vertebral bodies may be determined according to the chart of
As shown in
As demonstrated in
With the above information for a particular patient, incremental adjustment between adjacent vertebral bodies, and the corresponding complementary shape desired for the support panel 32 may be determined consistent with
In an embodiment of the invention, the curvature may be adjusted by utilizing flexible cords connecting rear surfaces of a supporting panel relative to one or more fixed points relative to a belt. Tension in the flexible cord produces a curvature in the surface of the supporting panel between the belt and the fixed points. This may again be provided for with one or more supporting panels. This can be structured to result in the desired curvature to the surface abutting the patient's back and application of the desired curvature to the spine of the patient. In this embodiment, two cords may be used, one for each lateral side of the device, but these cords may also be interconnected or adjusted through a single mechanism for providing consistent or equivalent force to each cord such that the adjustments to each side of the front section are consistent.
Additional embodiments may provide for adjustment of the curvature of the surface of the front section in different manners including but not limited to use of air pockets inflated or deflated as needed or adjustable length braces or rods extending between the main section and the front section.
In use, the support panel 32 of support panels 32 are shaped with the bend lines 44 or changes in thickness to provide the desired adjustment to the curvature as the adjustment line 38 is pulled. The support panel 32 is coupled to the belt 12 to rest against the back of the user in the desired position. The belt 12 is secured to the torso and the adjustment line 38 is pulled to adjust the curvature of the curved surface 34 either to a comfortable position, or using marks 42 to a specific setting to be complementary to a prescribed degree of lordosis for the particular user.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
