Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to the field of orthopedic supports and braces, and more particularly to a knee brace with improvements in more intuitive donning, doffing and comfort.

2. Description of the Related Art

Certain specialized orthopedic knee braces and supports are used to address osteoarthritis (OA). This is typically achieved by employing a plurality of rigid support members positioned adjacent to the body on either side of the skeletal joint being stabilized. The manner of fixation and articulation of the brace creates corrective forces that relieve condyle knee pain. Orthopedic braces are medical devices where design focus is mainly on function. While they can be effective, they are often bulky and heavy with excessive rigid framework. They typically employ a multitude of straps that require continuous lacing and unlacing each time, making it tedious to don and doff. Their overall size and coverage area over the limb can trap heat generated by activities of daily living making the brace uncomfortable to wear. These factors decrease patient compliance even against the benefits of pain relief and mobility.

As will be disclosed below, the present invention addresses all of these issues. The device is designed to be light by reducing the size of the framework. It uses a single sided framework made of light but strong metal components. The frame is integrated with plastic cuffs that are designed for toughness and a balance of flexibility and rigidity where necessary. The cuffs have significant openings to allow air flow.

The use of a multitude of straps is most effective in stabilization of the knee and migration of the brace. The straps are engineered with quick release attachments. This eliminates the need for threading the straps each time it is used. Additionally, it allows for the strap lengths to be preset, minimizing the need to adjust the straps.

Unloading is achieved by independently articulating the frame section directly adjacent to the knee joint. The present invention includes means to easily adjust the amount of unloading while providing minimal intrusion into site of the knee infirmity.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings and the characters of reference marked thereon, FIGS. 1-5 illustrate a preferred embodiment of the orthopedic device of the present invention, designated generally as 10, shown positioned on the leg of the user, shown in phantom lines 12. The orthopedic device 10 includes an articulating frame designated generally as 14, and four straps designated generally as 16, 18, 20, and 22. These four straps include a first thigh strap 16, a second thigh strap 18, a first calf strap 20, and a second calf strap 22.

The articulating frame 14 includes a thigh portion 24, a calf portion 26, and a center hinge assembly 28. The thigh portion 24 includes a semi-flexible curved thigh cuff 30 having an upper end 32 configured to wrap anterior to the leg 12 and a lower end 40. The calf portion 26 includes a semi-flexible curved calf cuff 34 having a lower end 36 configured to wrap posterior to the leg 12 and an upper end 38. The term “semi-flexible” as used herein relative to each cuff refers to the ability of each cuff to conform to the curvature profile of the user's leg. Each cuff is preferably formed of an polyester elastomer plastic approximately 3 mm thick. An example material that can be used is sold by Dupont under the trademark Hytrel® 7246 which is a high modulus grade with nominal hardness of 72D. The semi-flexible curved thigh cuff 30 preferably includes a flexible strap anchor 31 at said upper end thereof which provides improved conformability to the leg.

The center hinge assembly 28 connects the thigh portion 24 and the calf portion 26. The center hinge assembly 28 includes a center hinge element 42, a first Q-angle adjuster 44, and a second Q-angle adjuster 46. The first Q-angle adjuster 44 is positioned between the center hinge element 42 and the thigh portion 24 and is configured to adjust the Q-angle of the thigh portion 24 of the articulating frame 14. The second Q-angle adjuster 46 is positioned between the center hinge element 42 and said calf portion 26 and is configured to adjust the Q-angle of the calf portion 26 of the articulating frame 14. The Q-angle adjusters 44, 46 are configured to adjust the Q-angle of the articulating frame 14 in the coronal (i.e. frontal) plane. The Q-angle adjusters 44, 46 apply an unload force in the transverse (i.e. horizontal) plane. They can be adjusted in towards the knee or out away from the knee to provide either a push or pull unloading force, respectively. The center hinge assembly 28 includes an insert at each side for limiting flexion and extension. The center hinge assembly 28 shown is a polycentric hinge; however, a monocentric hinge can be substituted.

The thigh portion 24 includes an upright thigh bar 48 having an upright thigh bar first end 50 and an upright thigh bar second end 52. The upright thigh bar first end 50 is connected to the center hinge assembly 28. The upright thigh bar second end 52 fits into a thigh pocket 54 formed in the thigh cuff 30. The calf portion 26 includes an upright calf bar 56 having an upright calf bar first end 58 and an upright calf bar second end 60. The upright calf bar first end 58 is connected to the center hinge assembly 28. The upright calf bar second end 60 fits into a calf pocket 62 formed in the calf cuff 34. The upright thigh bar second end 52 and the upright calf bar second end 60 are stepped to provide a low profile integration of frame to cuff.

The upper end 32 of the semi-flexible curved thigh cuff 30 includes an upper thigh slot 64 and an upper thigh attachment element 66. The lower end 40 of the semi-flexible curved thigh cuff 30 includes a lower thigh slot 68 and a lower thigh attachment element 70. The upper end 38 of the semi-flexible curved calf cuff 34 includes an upper calf slot 72 and an upper calf attachment element 74. The lower end 36 of the semi-flexible curved calf cuff 34 includes a lower calf slot 76 and a lower calf attachment element 78.

The first thigh strap 16 includes a first thigh strap anchor end 80 securely attachable to the upper thigh slot 64. A first thigh strap adjustment end 82 is securely attachable to the upper thigh attachment element 66. The second thigh strap 18 includes a second thigh strap anchor end 84 securely attachable to the lower thigh slot 68. A second thigh strap adjustment end 86 is securely attachable to the lower thigh attachment element 70. The first calf strap 20 includes a first calf strap anchor end 88 securely attachable to the upper calf slot 72. A first calf strap adjustment end 90 is securely attachable to the upper calf attachment element 74. The second calf strap 22 includes a second calf strap anchor end 92 securely attachable to the lower calf slot 76. A second calf strap adjustment end 94 is securely attachable to the lower calf attachment element 78.

In this embodiment the attachment elements 66, 70, 74, 78 are latch mechanisms, discussed below in detail.

The upper calf slot 72 is angled to follow the curvature of a user's upper calf to minimize migration of the orthopedic device.

Referring now to FIGS. 6A-6D the upper thigh attachment element (latch mechanism) 66 is shown enlarged.

The latch mechanism 66 includes a lever assembly 96, a draw bar 98, and, a chafe 100.

Each lever assembly 96 includes a lever 102 having a looped first end 103, a lever axle 104 depending from the lever 102 at a second end thereof, for securing the lever 102 to a support structure (e.g. upper end of thigh cuff 30) of the orthopedic device 10; and, a snap fit hook 110 projecting from the lever 102.

The draw bar 98 is pivotably attached to the lever 102. The chafe 100 is attached to the draw bar 98. A catch 106 extends from the support structure (i.e. upper end of thigh cuff 30) to receive the lever axle 104. A snap fit ledge 108 depends from the support structure 30 to engage and hold the snap fit hook 110. The catch 106 is configured to stand substantially above a nominal height of the support structure 30 such that the lever axle 104 is easily received by the catch 106 for fastening by the user. The nominal height is the height of the outside surface of support structure 30 at the region where the catch 106 extends from the support structure 30. Thus, the term “substantially above” refers to a height above the diameter/thickness of the lever axle 104. The chafe 100 is preferably a D-ring chafe.

A press location 112 is located on the lever 102 adjacent to looped first end 103.

To close the latch mechanism 66 the user engages the lever axle 104 against the catch 106, pushes down on the looped first end 103, presses at the press location 112, pushes down until the snap fit hook 110 engages the snap fit ledge 108, and pushes the draw bar 98 down.

To open the latch mechanism 66 the user pulls the looped first end 103 to disengage the snap fit hook 110 from the snap fit ledge 108. As can be seen in FIG. 6C user engagement of the looped first end is illustrated to open the latch mechanism.

FIG. 6D shows the last steps in closing the latch mechanism 66, illustrating the user pressing at the press location 112 and pushing down until the snap fit hook 110 engages the snap fit ledge 108. He then pushes the draw bar 98 down.

Thus, separate locations are utilized for engagement and release of lever. This embodiment utilizes separate locations for engagement and release of lever 102. It provides mechanical advantage for snap fit hook 110 engagement. The press location 112 is at the approximate midline of lever 102. This ensures the snap fit hook 110 is engaged with a light tactile force. The location 112 is configured for intuitive use by its distinctive geometry differentiation from the surrounding area. The lever release, i.e. looped first end 103, is at an alternate location and is at the end of the lever 102. This looped first end 103 tab-like geometry is configured to flex and allow convenient access thereunder. This ensures the snap fit hook 110 is disengaged when intended. The flexion characteristic of the looped first end (i.e. end tab) 103 minimized undesired hook 110 engagement and encourages the user to the press location 112 to engage the lever 102.

Referring now to FIGS. 7-11, a second embodiment of the orthopedic device is illustrated, designated generally by 10′. This embodiment includes attachment elements that are pushbutton assemblies 114 rather than latch mechanisms 66. Other than the differing strap attachments, orthopedic device 10 is the same as 10′.

Each of the straps 16, 18, 20, 22 has a pushbutton clip at a free end, i.e. strap clip engagement end 116 thereof. A strap pushbutton clip 118 includes a D-ring section. The strap pushbutton clip 118 provides means for quick attachment or release of the thigh strap 18 from the articulating frame 14 for donning and doffing.

Referring now to FIGS. 12A-12C, the pushbutton clip 118 and integral pushbutton receptacle 120 provide quick attachment or release of the strap 18 from the articulating frame 14 for donning and doffing. The pushbutton assembly is illustrated, which collectively includes the receiver component (i.e. receptacle 120) that is integral with the cuff, and the pushbutton clip 118 (i.e. chafe) that attaches to the strap 16, 18, 20, or 22. The receptacle 120 has a slot 123 for the pushbutton clip 118 to slide into, a hole 124 for a button 126 to snap into and retain the clip 118 plus a dished-out area 128 that allows the finger to easily navigate to the button that also helps prevent accidental pressing of the button. The pushbutton clip 118 has a slot 123 for the strap to attach through, a thin area of plastic 125 between the slot 124 and the button 126 (on the concave pushbutton portion of the clip), that allows the pushbutton clip to flex in order to match the circumference of the anatomy and the button 126. The button 126 has a round shape that allows the pushbutton clip 118 to rotate so that the strap can follow the shape of the anatomy. The button 126 in the middle of this round shape has a dished out area 130 that helps prevent accidental pressings which is also more intimate with the shape of the finger that allows for easier pressing. There is a dome 131 in the middle of this dish and a concentric ridge 132 on the exit side that helps the finger get a good grip to activate the button. This button has a flexible hinge area 134 that allows the button 126 to flex out of the way of the receiver hole's wall 136 for removal. The receiver hole's wall 136 has a lead-in chamfer 138 on the upper outside edge created by the slot opening 122. The chamfer 138 assists an entry side 140 of the button 126 through slot 122. It also has two stops 142 that allows the button to not get flexed up into the receiver's hole 124 too far so that the flexible hinge 134 does not get sprung. The height of the button 126 is lower on the entry side 140 so that it is easy to insert but is higher on an exit side 144 for retention. This graded height also flexes the receiver's top section with the hole 124 to slightly flex out of the way for insertion. The entry side 140 is still high enough that the button 126 doesn't accidently disengage itself when the pushbutton clip 118 is rotated while in the receiver 120. The exit side 144 is high enough for retention, but still can slide through the slot opening 122 of the receiver 120 when being activated. The location of the hinge 134 and stops 142 along with the exit side 144 of the button allows the button to flex and remain intimate with the receiver's hole wall 136 when being flexed around the anatomy and when stronger forces are being applied from the strap so that the pushbutton clip 118 does not get pulled out of the receiver 120 (receptacle).

Referring now to FIGS. 13A and 13B strap adjustment is illustrated. In FIG. 13A the strap tension is shown being adjusted at the adjustment end 82 by the use of hook and loop fasteners. Such a fastening system may use VELCRO® fasteners or fasteners manufactured by Paiho North America. The strap adjustment is for the initial fitting to the leg. Subsequently, the device can be removed and refitted using the latch mechanism or pushbutton.

Referring now to FIGS. 14A and 14B a supplementary orthopedic support wrap is illustrated, designated generally as 150. This support wrap 150 can be used in conjunction with the orthopedic brace 10 for soft tissue containment in the thigh area. The support wrap 150 includes a substrate, designated generally as 152, that includes an elastic layer, for example, a neoprene layer 154, a loop material layer 156 bonded to one side of the neoprene layer 154, and a target area (i.e., placement position) 158 on the loop material layer 156. (The target area 158 may be sewn on the loop material layer as shown in FIG. 14B so that the stiches 158 for the target area go through the substrate and can be seen on the other side, as shown in this figure. Alternatively, the target area may be imprinted with a different color from the loop material layer 156.)

The support wrap 150 includes at least one relocatable stay 160 with one side having hook material for engagement with the loop material layer 156. The relocatable stays 160 include at least one strap engagement loops 162 for engaging a thigh strap of the orthopedic brace. In the embodiment shown two strap engagement loop 162 are shown, one for each thigh strap. A support wrap tab 164 is secured to one end of the substrate 152, having hook material on one side thereof for engagement with the loop material layer 156. A finger opening 166 provides ease of applying the support wrap 150.

During use, the support wrap 150 is positioned between the user's thigh and the orthopedic brace 10 to contain excessive soft tissue during application of the orthopedic brace 10 minimizing skin impingement.

This support wrap 150 can be used with various types of orthopedic braces, for example, as described in U.S. Pat. No. 10,369,037.

Referring now to FIGS. 15, a tibia cuff extension is illustrated, designated generally as 168, shown affixed to an orthopedic brace 10, shown in phantom. The tibia cuff extension 168 includes a tibia cuff liner 169 having an attachment portion 170 attachable to the inside of the calf cuff of the orthopedic brace 10. An upper calf strap portion 172 extends from the attachment portion 170. A lower calf strap portion 174 extends from the attachment portion 170.

A thermoformable shell 176 is attached to the attachment portion and to the lower calf strap portion 174. A fastening strip 178 is secured to the thermoformable shell 176.

During use the user attaches the tibia cuff extension 168 to the inside of the calf cuff 34, applies heat to the thermoformable shell 176, and presses the lower calf strap portion 174 against the tibia forming it over the tibia crest to enhance rotational control of the orthopedic brace 10. Application of heat to the thermoformable shell 176 can be provided by an adhesive exothermic heat pack or a heat gun while the lower part of the liner 169 remains in place. The lower part of the liner 169 protects the patient from the heated thermoformable shell 176 while being formed to the patient's tibia.

The tibia cuff extension 168 preferably includes lower strap control tabs 180 for maintaining the location of the straps. Additionally, the tibia cuff extension 168 preferably includes a movable upper tibia cuff strap control tab 182 for maintaining the position of the upper calf strap. The movable upper tibia cuff strap control tab 182 can be positioned to avoid the tibia crest on legs of different circumferences.

This tibia cuff extension 168 can be used with various types of orthopedic braces, for example, as described in U.S. Pat. No. 10,369,037.

During donning the user, in an initial fitting, presses the orthopedic device against his leg. The Q-angle adjusters are adjusted to fit the contour of his leg. The straps are wrapped around the leg, attaching free ends of the straps to the articulating frame, and adjusting the tension of the straps as desired. After this initial fitting the Q-angle adjusters can be adjusted accordingly to achieve pain relief.

As mentioned above, other embodiments and configurations may be devised without departing from the spirit of the invention and the scope of the appended claims.
