Description

Technical Field

[0001] This disclosure generally relates to orthotics, and more specifically, to shoulder slings for supporting and stabilizing the shoulder after surgery or injury. Background Technology

[0002] The shoulder is a relatively complex joint in the body, capable of rotation in multiple planes when the arm is displaced relative to the torso. Treatment of shoulder injuries often requires determining the optimal treatment position for the shoulder and associated arm, and placing them in that desired position. Such rehabilitation is particularly suitable for soft tissue injuries involving damage to one or more connective ligaments of the shoulder, and is often a treatment option following any number of surgical procedures, such as, but not limited to, surgery for recurrent posterior subluxation, rotator cuff surgery, and correction of fractures of the humeral head or shaft.

[0003] Shoulder support devices, such as orthotic braces, rigid castings, and slings, are commonly used to perform this type of placement and immobilization. However, at least in part, due to the use of one or more conventional shoulder straps that apply considerable force to the user's neck, and because users often experience confusion when multiple such straps are used, there remains a need for shoulder orthotics that offer greater comfort and versatility during immobilization, are easier for clinicians and / or patients to use, and reduce confusion. Summary of the Invention

[0004] According to some embodiments, a shoulder restraint device is provided. The device includes a forearm sling configured to receive the elbow, forearm, and wrist of a user's first arm. The forearm sling further includes a first fastener configured to secure a rear strap to a proximal portion of the forearm sling adjacent to the user's elbow. The forearm sling also includes a second fastener configured to secure a front strap to a distal portion of the forearm sling adjacent to the user's wrist. The device includes a counter-strap retainer. The counter-strap retainer includes a circumferential shoulder strap configured to wrap around the shoulder of the user's second arm to form a generally elliptical opening abutting against one of a chest area, a scapular area, and an axillary area or a laterally lateral portion of the shoulder of the second arm. The rear strap has a first swivel fastener configured to rotatably couple to one or more locations on the rear portion of the circumferential shoulder strap. The front strap has a second rotating fastener configured to be rotatably coupled to one or more locations on the front portion of the circumferential shoulder strap. The side strap retainers do not exert force on the user's neck.

[0005] According to some embodiments, a method of using a shoulder restraint device is provided. The method includes securing the elbow, forearm, and wrist of a user's first arm into a forearm sling. The forearm sling includes a rear strap and a front strap, the rear strap being secured to a proximal portion of the forearm sling adjacent to the user's elbow using a first fastener, and the front strap being secured to a distal portion of the forearm sling adjacent to the user's wrist using a second fastener. The method includes wrapping the circumferential shoulder strap of the opposite side strap retainer of the shoulder restraint device around the shoulder of the user's second arm to form a generally elliptical opening abutting against one of a chest area, a scapular area, and an axillary area, and a laterally lateral portion of the shoulder of the second arm. The method includes rotatably coupling a first rotating fastener of the rear strap to one or more locations on the rear portion of the circumferential shoulder strap. The method includes rotatably coupling a second rotating fastener of the front strap to one or more locations on the front portion of the circumferential shoulder strap, wherein the opposite side strap retainer does not exert force on the user's neck.

[0030] Turning to the accompanying drawings, where similar reference numerals denote similar elements, the techniques of this disclosure are illustrated for implementation in suitable settings. The following description is based on embodiments of the claims and should not be construed as limiting the claims with respect to alternative embodiments not explicitly described herein.

[0031] The phrases “connected to,” “coupled to,” and “communicating with” refer to any form of interaction between two or more entities, including mechanical, electrical, magnetic, electromagnetic, fluid, and thermal interactions. Two components can be functionally coupled to each other even if they are not in direct contact. The term “adjacent” refers to parts that are in direct physical contact with each other, but these parts are not necessarily attached together.

[0032] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are presented in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0033] The terms “orthotics” or “corrective device” are used herein to refer to braces, slings, or other such devices. Therefore, orthotics may be used interchangeably with the terms “braces” and / or “slings”, and when specified, may refer to a particular type of brace and / or sling (e.g., shoulder orthotics, shoulder braces, and / or shoulder slings).

[0034] A better understanding of the various features of this disclosure can be obtained from the following description, taken in conjunction with the accompanying drawings, in which similar reference numerals refer to similar elements where reasonably applicable. While this disclosure may be readily modified and alternatively constructed, certain illustrative features are shown in the drawings and described in detail below. However, it should be understood that this disclosure is not intended to be limited to the specific embodiments disclosed, but rather is intended to cover all modifications, alternatives, combinations, and equivalents falling within the spirit and scope of this disclosure.

[0035] Furthermore, it should be understood that unless a term is explicitly defined in this disclosure to have the meaning described, it is not intended to explicitly or indirectly limit the meaning of the term beyond its simple or ordinary meaning.

[0036] To facilitate understanding of the characteristics of the disclosed orthopedic devices, as used herein, "proximal" has its general meaning and refers to a position immediately adjacent to or close to the attachment point, origin point, or center point, or positioned towards the center of the body. Similarly, the term "distal" has its general meaning and refers to a position distant from the attachment point, origin point, or center point, or positioned away from the center of the body. The term "middle" refers to a position closer to the midline of the body, while the term "lateral" refers to a position further away from the midline of the body. The term "posterior" also has its general meaning and refers to a position behind or posterior to another location or feature. Finally, the term "anterior" has its general meaning and refers to a position in front of or in front of another location or feature.

[0037] The terms “rigid,” “flexible,” “ductile,” and “elastic” are used herein to differentiate certain characteristics of orthopedic devices. The term “rigid” is intended to indicate that the components of the device are generally or substantially inflexible. In the context of a rigid frame or support structure or housing, it is intended to indicate that they do not lose their overall shape when forces are applied. In contrast, the terms “flexible” or “ductile” are intended to encompass features that can bend or flex under load.

[0038] Embodiments of this disclosure relate to shoulder straps for securing the shoulders. Advantages of shoulder straps according to one or more embodiments described herein include lightweight construction, ease of application, quick and easy customization and / or adjustment of one or more sizes of the strap to provide a more precise and / or comfortable fit for the user, quick and easy adjustment of abduction and / or external / internal rotation, and easy conversion from left-shoulder user to right-shoulder user and vice versa. Additional features include the ability to employ precise amounts of abduction and external / internal rotation, and a breathable design.

[0039] Current market products are bulky and employ one or more shoulder straps that can impact nerves in the clavicular region (e.g., the proximal and / or middle portion of the clavicle), leading to neck pain and discomfort. Among other potential features, by using a contralateral strap retainer configured to support the sling and / or rest against the user's body on the opposite side of the chest, scapular, and axillary regions, the need for a conventional neck strap is eliminated compared to the shoulder / arm secured by the sling, shoulder device, or orthosis described herein, thus eliminating the associated pain and discomfort. Furthermore, the device's low-profile design reduces the bulk and weight present in other designs and allows for greater breathability and / or adjustability, thereby reducing patient discomfort when wearing the orthosis. Compared to existing sling designs, the sling described herein secures and supports the wearer's arm and shoulder in a comfortable, compliant, and convenient manner. In fact, the sling disclosed herein offers numerous advantages for individuals recovering from shoulder injuries, rotator cuff surgery, or other soft tissue strains. As will be described in more detail below, the telescopic adjustable strap system and universal sling can accommodate various patient sizes. Furthermore, the sling can fit either the wearer's right or left arm.

[0040] In some embodiments, an orthosis can be used to address a variety of conditions, including but not limited to: glenohumeral dislocation or subluxation, capsular displacement, posterior shoulder stabilization, Bankart repair, release of severe anterior capsular contracture, soft tissue strain or repair, rotator cuff repair, total shoulder replacement, superior labral repair (SLAP), shoulder debridement, fractures (humerus, elbow, forearm), biceps tendon repair, elbow ligament / tendon repair, anterior shoulder dislocation, and AC joint reconstruction.

[0041] The following discussion will take into account one or more embodiments of the shoulder fixation device according to the present disclosure, with reference to one or more accompanying drawings.

[0042] Figure 1 The illustration shows a shoulder restraint device 100 mounted on a user according to some example embodiments. Figure 2A and Figure 2B The illustrations depict examples of several embodiments. Figure 1 A shoulder restraint device 100, wherein the user is not shown for ease of reference. The shoulder restraint device 100 includes a forearm sling 110 configured to receive the elbow, forearm, and wrist of the user's first arm. This will be combined with at least the following... Figures 3-7 The forearm sling 110 and its associated examples will be discussed in more detail.

[0043] The forearm sling 110 also includes a first fastener 115 configured to secure the rear strap 139 to the proximal portion of the forearm sling 110 adjacent to the user's elbow when the user's arm is properly positioned in the sling 110. In some embodiments, the first fastener 115 may include one or more of a buckle, loop, strap receiving slot, hook-and-loop fastener, or any other suitable means for securing the strap to the proximal portion of the forearm sling 110.

[0044] The forearm sling 110 also includes a second fastener 114 configured to secure the front strap 131 to the distal portion of the forearm sling 110 adjacent to the user's wrist when the user's arm is properly positioned in the sling 110. In some embodiments, the second fastener 114 may include one or more of a buckle, loop, strap receiving slot, hook-and-loop fastener, or any other means for securing the strap to the distal portion of the forearm sling 110. In some embodiments, the second fastener 114 may include two such buckles, loops, strap receiving slots, or other means for securing the strap to the distal portion of the forearm sling 110. In some such embodiments, each such buckle, loop, strap receiving slot, or other fastening means may be configured to secure the front strap 131 to the distal portion of the forearm sling 110, on either upper edge of the forearm sling 110, adjacent to the user's wrist. In some such embodiments, at least one such buckle, loop, belt receiving slot or other fastening device may also be configured to attach and / or couple the forearm sling 110 to the waist belt 120.

[0045] In some embodiments, the forearm sling 110 further includes a third fastener 152 configured to secure around the user's wrist when the user's arm is properly positioned in the sling 110. In some embodiments, the third fastener 152 may include a hook-and-loop fastener (or any other suitable fastening device) configured to be releasably coupled to at least one compatible portion 154 of the forearm sling 110, the compatible portion being generally positioned between the distal portion of the forearm sling 110 (where the front strap 131 is fastened to the forearm sling 110) and the proximal portion of the forearm sling 110 (where the rear strap 139 is fastened to the forearm sling 110).

[0046] In some embodiments, the forearm sling 110 further includes a fourth fastener 156 configured to secure around at least a portion of the user's hand when the user's arm is properly positioned in the sling 110. For example, the fourth fastener 156 may be configured to extend between the thumb and forefinger of the hand of the arm positioned in the sling 110, such that the user's hand and / or arm is further secured to and / or restrained within the sling 110. In some embodiments, the fourth fastener 156 may include a hook-and-loop fastener (or any other suitable fastening device) configured to be releasably coupled to at least one compatible portion 158 of the forearm sling 110 positioned at the distal portion of the forearm sling 110.

[0047] The forearm sling 110 also includes a contralateral strap retainer 130. The strap retainer 130 includes a circumferential shoulder strap 138 configured to wrap around the shoulder of the user's second arm to form a generally elliptical opening 132 (see, for example, Figure 8 The opening should at least meet the chest area, scapular area, and axillary area (see example). Figure 1 , Figure 11A and Figure 11B ) or the lateral outward portion of the shoulder on the opposite side of the user's second arm (see, for example, Figure 10 One of them. This will be combined with the following... Figures 8-11B At least one of them is discussed in more detail regarding the side strap retainer 130, the circumferential shoulder strap 138 and its associated examples and / or portions.

[0048] This disclosure now turns to, at least in combination with Figures 1-7 Aspects of one or more example forearm slings 110, 310, 410, 510, 610, and 710 described herein. In some embodiments, one or more of the forearm slings 110, 310, 410, 510, 610, and 710 comprise a lightweight, breathable, and non-slip material. In some embodiments, one or more of the forearm slings 110, 310, 410, 510, 610, and 710 comprise an inner mesh, a full lining, and / or an outer tube, and in some cases, they may include foam material disposed therein and a plurality of ventilation holes.

[0049] For example, Figure 3 The illustration shows a forearm sling 310 of a shoulder restraint device according to some example embodiments, having a plurality of vents 312. In some such embodiments, the vents 312 may have a generally circular or slightly elongated shape. In some embodiments, the vents 312 may have a maximum diameter (e.g., 1 / 16 inch or less) to prevent window edema. However, this disclosure is not limited thereto, and the vents 312 may have any shape and / or size suitable for the applications discussed herein.

[0050] As yet another example, Figure 4 The illustration shows another forearm sling 410 of a shoulder restraint device according to some example embodiments, which has a plurality of elongated vent holes 412. In some such embodiments, the vent holes 412 may have a generally elongated shape, such as oval, rectangular, and / or rectangular with generally rounded corners. In some embodiments, the vent holes 412 may have a maximum diameter (e.g., 1 / 16 inch or less) to prevent window edema. However, this disclosure is not limited thereto, and the vent holes 412 may have any shape and / or size suitable for the applications discussed herein.

[0051] As yet another example, Figure 5 The illustration shows another forearm sling 512 of a shoulder restraint device according to some example embodiments, which has a generally open mesh 512. In some such embodiments, the generally open mesh 512 allows the opening portion of the mesh 512 to occupy a large portion of the surface area of ​​the forearm sling 510. In some embodiments, the opening in the generally open mesh 512 may have a maximum diameter (e.g., 1 / 16 inch or less) to prevent window edema. However, this disclosure is not limited thereto, and the opening in the generally open mesh 512 may have any shape and / or size suitable for the applications discussed in this disclosure.

[0052] In some embodiments, one or more of the forearm slings 110, 310, 410, 510, 610, and 710 include one or more slits to increase user comfort. For example, Figure 6 The illustration shows another forearm sling 610 of a shoulder restraint device according to some example embodiments, which has a cutout 616 configured to expose the user's elbow when the user's arm is properly positioned in the forearm sling 610. In some such embodiments, when the first arm is properly positioned within the sling 100, the forearm sling 610 does not contact at least a portion of the user's first arm's elbow, thereby reducing or eliminating associated pressure points and increasing user comfort.

[0053] Alternative or additional land, such as Figure 7 As shown, according to some example embodiments, another forearm sling 710 may include one or more cuts 716a, 716b configured to expose the upper portion of the user's forearm. In some such embodiments, the forearm sling 710 does not contact one or more portions of the user's forearm along its top edge to further increase user comfort.

[0054] Although the above combination Figures 1-7Several embodiments of forearm slings have been described, but this disclosure also contemplates any and all embodiments including any combination of features described herein, in a single forearm sling, and in some cases even including embodiments in which the forearm sling includes a complete sleeve that is substantially not open at its top, such as... Figures 1-7 Any one of them is shown.

[0055] This disclosure now turns to, at least in combination with Figures 1-2B and Figures 8-11B The described one or more examples are for the discussion of aspects of the sideband retainer 130. As combined with the above... Figures 1-2B Briefly described, the contralateral strap retainer 130 includes a circumferential shoulder strap 138 configured to wrap around the shoulder of a user's second arm to form a generally elliptical opening 132 or arm loop that at least abuts against one of the chest region, scapular region, and underarm region, or the laterally lateral portion of the shoulder of the user's second or contralateral arm. In some embodiments, the cross-section of the generally elliptical opening 132 may be generally circular. In some embodiments, the cross-section of the generally elliptical opening 132 may be generally oval or elliptical. In some embodiments, the generally elliptical opening 132 is generally about... Figure 8 The symmetrical dotted lines shown allow the sling 100 to be used on either shoulder without substantial adjustment. In some embodiments, the circumferential shoulder strap 138 may also include padding to further enhance user comfort.

[0056] like Figures 1-2B , Figure 8 and Figure 9 As shown in at least one of them, the front strap 131 may be coupled and / or is capable of being coupled to the front portion of the circumferential shoulder strap 138, while the rear strap 139 may be coupled and / or is capable of being coupled to one or more positions on the rear portion of the circumferential shoulder strap 138. (As will be combined) Figure 11A and Figure 11B A more detailed description, and as at least in Figure 2B As further shown, the rear strap 139 may have a first rotating fastener 143 configured to be rotatably coupled to one or more locations on the rear portion of the circumferential shoulder strap 138. Similarly, the front strap 131 may have a second rotating fastener 133 configured to be rotatably coupled to one or more locations on the front portion of the circumferential shoulder strap 138. Thus, one or both of the front strap 131 and the rear strap 139 are configured to extend between the forearm sling 110 and the circumferential shoulder strap 138, without wrinkles or folds.

[0057] Because the circumferential shoulder strap 138 is configured to wrap around the user's opposite shoulder to form a generally elliptical opening that abuts against one of the chest area, scapular area, and the lateral outward portion of the shoulder of the armpit or second arm, the opposite shoulder retainer 130 does not exert force on the user's neck as a conventional strap wraps around the neck or generally only around the top portion of the opposite shoulder.

[0058] In some embodiments, such as at least in combination Figure 9 As shown, the user can adjust the size of the generally elliptical opening 132 by adjusting the amount of overlap at the opposite ends 940 of the shoulder strap 138, which can be coupled to each other via any suitable type of fastener (e.g., hook-and-loop fastener) disposed on one or both ends 940 of the shoulder strap 138. In some embodiments, the opposite ends 940 of the shoulder strap 138 overlap each other at the top of the generally elliptical opening 132, for example, at the top of the generally elliptical opening 132 configured to rest against the opposite shoulder of the second arm, rather than generally resting only against the chest, scapula, or armpit portion of the opposite shoulder of the second arm. It has been found that, compared to the opposite ends 940 of the shoulder straps 138 overlapping at another portion of the elliptical opening 132 (e.g., at the bottom of the generally elliptical opening 132 or the axillary portion), which can interfere with vital signs of weight, the larger arm, and / or electrical transmission in larger patients during and / or after surgery, the opposite ends 940 of the shoulder straps 138 overlapping at the top of the generally elliptical opening 132 significantly facilitate the application of the forearm sling 100 to the patient while they are still unconscious or otherwise immobilized, for practitioners and medical personnel. The specific design of the forearm sling described in this disclosure is easier and less confusing for clinicians and patients to use than conventional slings, because knowing that the generally elliptical opening 132 is configured to wrap around the opposite shoulder of the second arm allows for simple and correct placement of the front strap 131 across the front of the patient's body, torso, and / or chest, and the rear strap 139 extending across the rear of the patient's body, torso, and / or chest.

[0059] In some embodiments, such as at least in combination Figure 10 As shown, the alternative circumferential shoulder strap 1038 can be configured in an over-arm orientation, so that it is compatible with... Figure 1 The portion corresponding to the shoulder strap 138 shown in Figure 2 extends around the underside of the user's contralateral arm (e.g., the armpit), rather than around the lateral aspect of the user's contralateral arm. In such an embodiment, the shoulder strap 1038 can be configured to apply force to the lateral aspect of the user's contralateral arm, rather than to the underside of the user's contralateral arm, while still providing similar neck pain relief benefits as the underarm embodiment, such as at least in combination with... Figures 1-2BThose described. In such an embodiment, the circumferential shoulder strap 1038 may have substantially the same features as the shoulder strap 138, except that a portion of the strap 1038 corresponding to the portion of the shoulder strap 138 configured to be placed along the armpit of the contralateral shoulder is instead configured to be placed along and / or around the lateral portion of the patient's contralateral shoulder for the circumferential shoulder strap 1038.

[0060] This disclosure now turns to a discussion of one or both of the front strap 131 and the rear strap 139 and one or more exemplary aspects of rotatable coupling between them and corresponding portions of the circumferential shoulder straps 138, 1038, such as in at least conjunction with Figures 1-2B , Figure 11A and Figure 11B As described. For example. Figure 11A The illustration shows a rotating fastener 133 according to some example embodiments, which is configured to rotatably couple a front strap 131 to the front portion of the circumferential shoulder straps 138, 1038, thereby allowing the front strap to extend between the forearm sling 110 and the circumferential shoulder straps 138, 1038 without wrinkling or folding. The rotating fastener 133 may include a stitched fabric loop 1137 or multiple stitched fabric loops 1137a, 1137b configured to be sewn or otherwise secured at one or more locations on the front portion of the circumferential shoulder straps 138, 1038, and a buckle having a slot 1134 configured to receive the front strap 131 and a rotating post 1135 (e.g., a snap-on rotating post) having a locking feature 1136 (e.g., a D-ring spring lock) configured to secure the rotating post 1135 to one fabric loop 1137 or to one of more than one fabric loop 1137a, 1137b. In some embodiments, the fabric loops 1137a, 1137b may also have stickers, patches, and / or identifiers of different colors, numbers, or other representations to easily guide the user to the appropriate loop so that the device 100 can be properly, safely, and comfortably fitted.

[0061] In some embodiments, a similar rotary fastener may be used to couple the rear strap 139 to the rear portion of the circumferential shoulder straps 138, 1038, as described above with respect to the front strap 131, thereby allowing the rear strap 139 to extend between the forearm sling 110 and the circumferential shoulder straps 138, 1038 without wrinkling or folding. For example, Figure 11BThe illustration shows a rotating fastener 143 according to some example embodiments, which is configured to rotatably couple a rear strap 139 to the rear portion of circumferential shoulder straps 138, 1038, thereby allowing the rear strap to extend between the forearm sling 110 and the circumferential shoulder straps 138, 1038 without wrinkling or folding. The rotating fastener 143 may include a stitched fabric loop 1147 or multiple stitched fabric loops 1147a, 1147b configured to be sewn or otherwise secured at one or more locations on the rear portion of the circumferential shoulder straps 138, 1038, and a buckle having a slot 1144 configured to receive the rear strap 139 and a rotating post 1145 (e.g., a snap-on rotating post) having a locking feature 1146 (e.g., a D-ring spring lock) configured to secure the rotating post 1145 to one fabric loop 1147 or to one of more than one fabric loop 1147a, 1147b. In some embodiments, the fabric loops 1147a, 1147b may also have stickers, patches, and / or identifiers of different colors, numbers, or other representations to easily guide the user to the appropriate loop for proper, safe, and comfortable fitting of the device 100.

[0062] This disclosure now turns to a discussion of one or more example abduction pads 120°, 130°, 140°, 150°, 160°, 170° for achieving a desired abduction angle of a user's arm relative to his or her torso, as in at least in conjunction with the following Figure 12-Figure 1 As described in 7. For example, Figure 12 An abduction pad 1200 for a shoulder immobilization device is illustrated according to some example embodiments. The abduction pad 1200 is shown as having an integral construction and having one end with a first thickness and an opposite end with a second thickness greater than the first thickness. Therefore, the abduction pad 1200 may be generally wedge-shaped. The abduction pad 1200 may include any suitable pad material, such as, but not limited to, memory foam, mattress material, or another foam or padding material. In some embodiments, the abduction pad 1200 may also include one or more recessed portions 1202 configured to secure the abduction pad 1200 between the user's immobilized arm and / or forearm and torso and establish a desired abduction angle.
