A multi-axial adjustable joint brace

Abstract

This invention provides a multi-axial adjustable joint brace, comprising a first brace assembly, a second brace assembly, and a hinge assembly. The hinge assembly includes a fixed block, a rotating block, and a rotating rod. One end of the fixed block has a gradually thinning thickness along its longitudinal direction, forming an inclined portion. One end of the rotating block is attached to the inclined portion. This invention is rationally designed and has a novel structure, facilitating early movement for patients after injuries to the upper arm, elbow, and forearm, preventing joint adhesions and muscle atrophy. It also offers good breathability, improving patient comfort. Most importantly, compared to existing braces, this design allows for slight lateral deviation during joint flexion and extension, better conforming to the physiological movement trajectory of the elbow joint, reducing secondary injuries caused by brace restrictions, and promoting better recovery of the injured area.

Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a multi-axial adjustable joint brace. Background Technology

[0002] A fracture is a complete or partial break in the continuity of bone structure, most commonly seen in children and the elderly, but also frequently occurring in young and middle-aged adults. After reduction, fractures are prone to redisplacement due to instability; therefore, various fixation methods are used to immobilize the fracture in a satisfactory position to promote healing. External fixation is a commonly used method, such as using splints or plaster casts. During treatment, patients also need to increase blood circulation to the surrounding tissues through muscle contraction of the injured limb, promoting fracture healing and preventing muscle atrophy. Active or passive movement of unfixed joints also helps prevent joint adhesions and capsular contractures, allowing the injured limb to recover its function to its pre-fracture state as quickly as possible. Traditional fixation methods can only immobilize the arm in a specific position, making it difficult for patients to move their forearms. In addition, plaster casts are bulky and not breathable, and long-term fixation can cause joint stiffness, muscle atrophy, and even severe functional impairment. Although the adjustable flexion and extension braces currently on the market have increased breathability and allowed for simple flexion and extension movements, the designed movement trajectory does not conform to the complex joint kinematics in reality, which greatly reduces patient comfort and rehabilitation effects, and is not conducive to the patient's treatment.

[0030] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed explanations follow: Example

[0031] Please see Figures 1 to 9 This embodiment provides a multi-axial adjustable joint brace, including a first brace assembly 1, a second brace assembly 2, and a hinge assembly 3; The hinge assembly 3 includes a fixed block 31, a rotating block 32, and a rotating rod 33; One side end of the fixing block 31 gradually becomes shallower along the longitudinal direction of the fixing block 31 and forms an inclined part; One end of the rotating block 32 is in contact with the inclined portion, and the rotating block 32 and the fixed block 31 are connected by the rotating rod 33; The first protective gear component 1 is connected to the fixing block 31; The second protective gear component 2 is connected to the rotating block 32.

[0032] In this embodiment, by setting a first protective gear component 1, a second protective gear component 2, and a hinge component 3, the patient wears the first protective gear component 1, the second protective gear component 2, and the hinge component 3 on their arm during use. The first protective gear component 1 corresponds to the patient's upper arm, the second protective gear component 2 corresponds to the patient's forearm, and the second protective gear component 2 can rotate relative to the first protective gear component 1 through the hinge component 3.

[0033] Because the fixed block 31 has an inclined part on one side, when the rotating block 32 rotates relative to the fixed block 31, in addition to the conventional vertical rotation, the rotating block 32 can also move closer to or away from the inclined part of the fixed block 31. In the naturally extended state, the human forearm has a certain lateral deviation relative to the upper arm, which is called the "carrying angle". Generally, it is 5°-10° for men and 10°-15° for women. During the flexion process of the forearm approaching the upper arm, the setting of the inclined part matches the "carrying angle" very well, which can more effectively help patients recover their health and improve their comfort.

[0034] Please see Figure 1 , Figure 8 and Figure 9 The first protective gear assembly 1 includes a first support 11 and a first connecting rod 12. The second protective gear assembly 2 includes a second support 21 and a second connecting rod 22. There are two first connecting rods 12, two second connecting rods 22, and two hinge components 3. The two first connecting rods 12 are respectively inserted into the left and right sides of the first support 11. The two second connecting rods 22 are respectively inserted into the left and right sides of the second support 21. One end of the two first connecting rods 12 extends out of the first support 11 and is fixedly connected to the two fixed blocks 31. One end of the two second connecting rods 22 extends out of the second support 21 and is fixedly connected to the two rotating blocks 32.

[0035] The first support 11 is designed to cooperate with the upper arm, and the second support 21 is designed to cooperate with the forearm. The two first connecting rods 12 and the second connecting rod 22, together with the two hinge components 3, can make the rotational connection between the first support 11 and the second support 21 more reliable.

[0036] In this embodiment, the tilting directions of the two fixed blocks 31 are set in opposite directions to better match the tilt of the forearm in the horizontal direction.

[0037] Please see Figures 1 to 4The first support 11 includes a first pad 111, a first guide rail 112, and a second guide rail 113. There are two first pads 111 arranged opposite to each other. Each first pad 111 includes a first pad plate 1111 and a first pad block 1112. The first pad block 1112 is disposed on the first pad plate 1111. Two first connecting rods 12 are respectively inserted into the left and right sides of the two first pad plates 1111. The lower end of one of the first pad plates 1111 is provided with the first guide rail 112 horizontally, and the lower end of the other first pad plate 1111 is provided with the second guide rail 113 that cooperates with the first guide rail 112.

[0038] By setting a first support pad 111, a first guide rail 112, and a second guide rail 113, the two first support pads 111 are slidably connected through the first guide rail 112 and the second guide rail 113, so that the two first support pads 111 can move closer or further apart in the horizontal direction to match the upper arm size of different patients, and can also be adjusted according to the thickness of the patient's clothing.

[0039] The first pad 1111 is used to provide support, and the first pad 1112 is used to increase comfort.

[0040] In this embodiment, there are two first guide rails 112 and two second guide rails 113 to ensure the sliding stability of the two first pads 1111.

[0041] In this embodiment, the first pad 1111 can be made of an arc-shaped plastic sheet with a horizontal end at the bottom, which is used to ensure that the first guide rail 112 or the second guide rail 113 can be installed stably.

[0042] Please see Figures 2 to 4 The first pad 1112 includes a first breathable pad 1113 and a first fleece pad 1114. A plurality of first magnetic blocks 1115 are fixedly disposed on the first pad plate 1111. The first breathable pad 1113 is fixedly disposed on the first pad plate 1111. The first pad plate 1111 is provided with a plurality of first vent holes. The first breathable pad 1113 is provided with second vent holes corresponding to the plurality of first vent holes. The first fleece pad 1114 is provided with first iron pieces 1116 corresponding to the plurality of first magnetic blocks 1115.

[0043] Considering that some patients require a long recovery period after a fracture, which can vary with the seasons, the design incorporates a first breathable pad 1113 and a first fleece-lined pad 1114. In warmer weather, patients can remove the first fleece-lined pad 1114 and use the first breathable pad 1113 to contact their upper arm for increased comfort. In colder weather, the first fleece-lined pad 1114 can be magnetically attached to the first padding plate 1111 and adhering to the first breathable pad 1113, or the first breathable pad 1113 can be removed, using only the first fleece-lined pad 1114 and the first padding plate 1111 for increased warmth.

[0044] Please see Figures 5 to 7 The second support 21 includes a second support pad 211, a third guide rail 212, and a fourth guide rail 213. There are two second support pads 211 arranged opposite to each other. Each second support pad 211 includes a second pad plate 2111 and a second pad block 2112. The second pad block 2112 is disposed on the second pad plate 2111. Two second connecting rods 22 are respectively inserted into the left and right sides of the two second pad plates 2111. The lower end of one of the second pad plates 2111 is horizontally provided with the third guide rail 212, and the lower end of the other second pad plate 2111 is provided with the fourth guide rail 213 that cooperates with the third guide rail 212.

[0045] By setting a second support pad 211, a third guide rail 212, and a fourth guide rail 213, the two second support pads 211 are slidably connected through the third guide rail 212 and the fourth guide rail 213, allowing the two second support pads 211 to move closer or further apart in the horizontal direction to match the forearm size of different patients, and can also be adjusted according to the thickness of the patient's clothing.

[0046] The second pad 2111 is provided for support, and the second pad 2112 is provided to increase comfort.

[0047] In this embodiment, there are two third guide rails 212 and two fourth guide rails 213 to ensure the sliding stability of the two second pads 2111.

[0048] In this embodiment, the second pad 2111 can be made of an arc-shaped plastic sheet with a horizontal end at the bottom, which is used to ensure that the third guide rail 212 and the fourth guide rail 213 can be installed stably.

[0049] Please see Figures 5 to 7The second pad 2112 includes a second breathable pad 2113 and a second fleece pad 2114. Several second magnetic blocks 2115 are fixedly provided on the second pad plate 2111. The second breathable pad 2113 is fixedly provided on the second pad plate 2111. Several third vent holes are provided on the second pad plate 2111. The second breathable pad 2113 is provided with fourth vent holes corresponding to the several third vent holes. Several second iron pieces 2116 corresponding to the second magnetic blocks 2115 are provided on the second fleece pad 2114.

[0050] Considering that some patients require a long recovery period after a fracture, which can vary with the seasons, the design incorporates a second breathable pad 2113 and a second fleece-lined pad 2114. In warmer weather, patients can remove the second fleece-lined pad 2114 and use the second breathable pad 2113 to contact their upper arm for increased comfort. In colder weather, the second fleece-lined pad 2114 can be magnetically attached to the second padding plate 2111 and adhering to the second breathable pad 2113, or the second breathable pad 2113 can be removed, using only the second fleece-lined pad 2114 and the second padding plate 2111 for increased warmth.

[0051] Please see Figures 2 to 7 The first pad 1111 has an arc-shaped structure, and the shape of the first pad block 1112 is adapted to the first pad 1111. The first pad 1111 has a first ring buckle 1117 on the left side and a first Velcro 1118 that cooperates with the first ring buckle 1117 on the right side. The second pad 2111 has an arc-shaped structure, and the shape of the second pad block 2112 is adapted to the second pad 2111. The second pad 2111 has a second ring buckle 2117 on the left side and a second Velcro 2118 that cooperates with the second ring buckle 2117 on the other side of the opening of the second pad 2111.

[0052] By setting the first pad 1111 and the second pad 2111 into an arc-shaped structure, the patient can smoothly wear the first protective gear component 1 and the second protective gear component 2. The ring buckle and Velcro can ensure that the first protective gear component 1 and the second protective gear component 2 can be securely worn on the patient's arm.

[0053] In addition, in this embodiment, both the first connecting rod 12 and the second connecting rod 22 can be configured as telescopic rod structures, and both the first connecting rod 12 and the second connecting rod 22 are provided with adjusting bolts.

[0054] Here, both the first connecting rod 12 and the second connecting rod 22 include a base rod, an extension rod, and an adjusting bolt. The extension rod is inserted into the base rod, and the extension rod achieves its overlap length with the base rod through the adjusting bolt, thereby adapting to the arm length of different patients. Example

[0055] Please see Figures 9 to 12 It also includes a lateral deflection auxiliary component 4. The fixed block 31 and the rotating block 32 on the left side are connected by the lateral deflection auxiliary component 4. The lateral deflection auxiliary component 4 includes a cylinder 41, a first connecting block 42, a tension / compression sensor 43, a second connecting block 44, and a controller 45. The cylinder 41 is horizontally fixed to the end of the fixed block 31 away from the rotating block 32 by a cylinder seat (not shown). The output end of the cylinder 41 extends from the fixed block 31 and is connected to the rotating block 32 by a support rod 47. The first connecting block 42 is disposed on the inclined portion. A groove 421 is provided at one end away from the inclined portion. The tension / compression sensor 43 is fixedly disposed in the groove 421. The second connecting block 44 is fixedly disposed on the side end of the rotating block 32 facing the fixed block 31 and directly opposite the first connecting block 42. A protrusion 441 is provided on the side end of the second connecting block 44. The protrusion 441 is connected to the signal input terminal of the tension / compression sensor 43 through a first spring 46. The controller 45 is disposed on the fixed block 31. The signal output terminal of the tension / compression sensor 43 and the cylinder 41 are electrically connected to the controller 45 respectively.

[0056] The working principle of the lateral deviation assist component 4 in this embodiment is as follows: When the patient rotates the forearm, the forearm will shift horizontally relative to the upper arm. The rotating block 32 on the left side moves together with the second connecting block 44 towards the side away from the inclined part. The protrusion 441 pulls the first spring 46. After the first spring 46 is stretched, the tension sensor 43 receives the stretching signal and transmits the signal to the controller 45. The controller 45 controls the cylinder 41 to extend, so that the output end of the cylinder 41 moves toward the rotating block 32 and transmits the thrust to the rotating block 32, assisting the patient's forearm to shift outward.

[0057] When the patient's forearm returns to its initial state from the rotated position, that is, when the forearm tilt angle decreases, the rotating block 32, along with the second connecting block 44, moves toward the side closer to the tilted part. The protrusion 441 presses against the first spring 46. After the first spring 46 is compressed, the tension sensor 43 receives a compression signal and transmits the signal to the controller 45. The controller 45 controls the cylinder 41 to contract, causing the output end of the cylinder 41 to move away from the rotating block 32. At the same time, it pulls the rotating block 32 to reset. The rotating block 32 is no longer resisted by the cylinder 41, which allows the patient's forearm to smoothly shift inward.

[0058] The controller model in this embodiment is STM32F103C8T6.

[0059] Please see Figure 10 and Figure 12It also includes a side tilt return component 5. The fixed block 31 and the rotating block 32 located on the right side are also connected through the side tilt return component 5. The side tilt return component 5 includes a spring seat 51 and a second spring 52. There are two spring seats 51, which are respectively fixedly installed on the side ends opposite to the fixed block 31 and the rotating block 32. The two ends of the second spring 52 are respectively connected to the two spring seats 51.

[0060] The working principle of the lateral deviation correction component 5 in this embodiment is as follows: when the patient's forearm deviates outward, the fixed block 31 and the rotating block 32 on the other side are squeezed, causing the second spring 52 to be squeezed. When the patient's forearm returns to the initial state from the rotating position, that is, when the forearm tilt angle becomes smaller, the rotating block 32 moves towards the side away from the tilted part, the second spring 52 restores its deformation, and transmits the elastic force to the rotating block 32, assisting the rotating block 32 to move towards the side away from the tilted part, thus assisting the patient's forearm to return to the initial state from the rotating position.

[0061] In this embodiment, one spring seat 51 is inclinedly mounted on the inclined part of the fixed block 31, and the other spring seat is vertically mounted on the rotating block 32.

[0062] In this embodiment, the lateral deviation assist component 4 also has a certain lateral deviation correction function during the contraction of the cylinder 41. In this embodiment, it should be noted that the sensitivity and speed of forearm rotation of patients who have suffered fractures are far less than those of normal people. By setting up the lateral deviation assist component 4 and the lateral deviation correction component 5, the forearm can be assisted to rotate or extend slowly, just like a normal person's, to produce a certain deviation angle, or to correct the forearm, which is closer to the normal activity of the human arm, thereby speeding up the patient's recovery from the fracture.
