[0002] Joint fixators, especially those used for the joints of the arms or legs, are used for orthopedic and shaping purposes. They provide fixation, allowing users to better secure their arms or legs for subsequent rehabilitation.

[0003] For example, US Publication No. US20020026136A1 discloses an orthotic joint for an orthosis in which two parts of the body can be bent and extended relative to each other, such as a knee or arm orthosis. The orthotic joint rotatably connects two splints, each splint being connected to the upper and lower parts of the orthosis that can be fixed to the corresponding parts of the body. A pair of splints with orthotic joints are respectively arranged on the sides and / or center of the orthosis. The splints engage with each other at the ends of the orthotic joint by one or more common pins or teeth. Adjustable end stops for extension and / or bending are provided, and the end stops are adjustable within one or more angular ranges.

[0004] However, when wearing a joint fixation device on the leg, it is necessary to properly limit the fixation device to prevent it from moving on the leg, especially during the user's walking process. It is necessary to prevent the joint fixation device from loosening or moving, which is a problem that urgently needs to be solved. Utility Model Content

The upper support 100 includes: an upper support arm 110 corresponding to the side of the leg, an upper surround 120 connected to the upper support arm 110 and extending in an arc towards the front of the thigh, and a first upper connecting strap 130 that cooperates with the upper surround 120 to secure the upper support 100 to the leg. The first upper connecting strap 130 is detachably assembled with the upper surround 120 and / or the upper support arm 110 via a quick snap fastener 140. The lower support 200 includes: a lower support arm 210 corresponding to the side of the leg, a lower surround 220 connected to the lower support arm 210 and extending in an arc towards the back of the calf, and a first lower connecting strap 230 that cooperates with the lower surround 220 to secure the lower support 200 to the leg. The first lower connecting strap 230 is detachably assembled with the lower surround 220 and / or the lower support arm 210 via a quick snap fastener 140.

[0044] This utility model of a joint fixation device for moderate osteoarthritis is designed for use by users with osteoarthritis. After wearing, the upper support arm 110 and the lower support arm 210 are positioned on the sides of the leg, while the upper surround 120 covers the front of the thigh (i.e., the front side) and the lower surround 220 covers the back of the calf (i.e., the back side). The device is then secured to the leg by the first upper connecting strap 130 and the first lower connecting strap 230, preventing it from loosening or shifting during user activity.

[0045] like Figure 1 As shown, the upper support arm 110 is located on the outside of the thigh, and the upper surround 120 is connected to the upper support arm 110 and extends from the outside of the thigh to the front of the thigh. The upper surround 120 does not completely cover the thigh. It is connected by the first upper connecting strap 130 to cover the thigh and fix the upper support 100 to the thigh.

[0046] Similarly, the lower support arm 210 is located on the outside of the lower leg, while the lower surround 220 is connected to the lower support arm 210 and extends from the outside of the lower leg to the front of the lower leg. The lower surround 220 does not completely cover the lower leg. It is connected by the first lower connecting strap 230 to cover the lower leg and fix the lower support 200 to the lower leg.

[0047] In this way, the joint fixation device for osteoarthritis can be fixed to the leg, with the upper band 120 limiting it from the front and the lower band 220 limiting it from the back, making it easier to wear.

[0048] In one embodiment, the quick-release snap 140 includes a male snap 141 and a female snap 142, which are inserted into each other.

[0049] Furthermore, the first upper connecting strap 130 can be disassembled on one side or both sides. In this embodiment, it is preferred to disassemble on one side. One end of the first upper connecting strap 130 is connected to the upper end of the upper support arm 110 and is at the same height as the upper enclosure 120. The other end of the first upper connecting strap 130 is provided with a male buckle 141 and the upper enclosure 120 is provided with a female buckle 142, which can realize quick assembly and disassembly.

[0050] The first lower connecting strap 230 can be disassembled on one side or both sides. In this embodiment, it is preferred to disassemble on one side. One end of the first lower connecting strap 230 is connected to the lower end of the lower support arm 210 and is at the same height as the lower enclosure 220. The other end of the first lower connecting strap 230 is provided with a male buckle 141 and the lower enclosure 220 is provided with a female buckle 142, which can realize quick assembly and disassembly.

[0051] In one embodiment, the upper support 100 is equipped with a second upper connecting strap 150, which is located below the upper enclosure 120 and helps to secure the upper support 100 to the leg.

[0052] The lower support 200 is equipped with a second lower connecting strap 250, which is located above the lower enclosure 220 and helps to fasten the lower support 200 to the leg.

[0053] The second upper connecting strip 150 and the second lower connecting strip 250 can be a single-segment structure or a multi-segment structure.

[0054] In one embodiment, the connecting mechanism 300 includes:

[0055] The activity module 310 assists the upper support 100 and the lower support 200 to swing relative to each other to adapt to the swing angle of the lower leg and thigh during walking;

[0056] Angle adjustment module 320 adjusts the angle between the upper support 100, the lower support 200 and the vertical axis;

[0057] Furthermore, two angle adjustment modules 320 are provided, one of which is connected to the lower end of the upper support 100 and the other is connected to the upper end of the lower support 200; the movable module 310 is connected between the two angle adjustment modules 320.

[0058] The angles between the upper support 100, the lower support 200 and the vertical axis are adjusted by two angle adjustment modules 320 to meet the needs of different users.

[0059] In one embodiment, the angle adjustment module 320 includes:

[0060] Support member 321: The support member 321 of one angle adjustment module 320 is fixedly connected to the upper bracket 100, and the support member 321 of the other angle adjustment module 320 is fixedly connected to the lower bracket 200. The support members 321 of both angle adjustment modules 320 are rotatably connected to the movable module 310.

[0061] Worm gear 322 and worm 323, the worm 323 is disposed at the connection between support 321 and movable module 310, and worm gear 322 and worm 323 mesh;

[0062] In use, an external force drives the worm gear 322 to rotate, which in turn drives the worm 323 to rotate, causing the support member 321 to swing relative to the movable module 310. Since one end of the support member 321 is connected to the upper bracket 100 and the lower bracket 200; assuming the position of the movable module 310 remains unchanged, when the worm 323 rotates, the support member 321 swings relative to the movable module 310. Figure 2As shown, if the upper angle adjustment module 320 is adjusted, the upper bracket 100 will rotate around the worm 323. The worm 323 is set horizontally, and the upper bracket 100 will swing inward or outward relative to the paper.

[0063] Similarly, continue as Figure 2 As shown, if the lower angle adjustment module 320 is adjusted, the lower support 200 will rotate around the worm gear 323. The worm gear 323 is set horizontally, and the lower support 200 will swing inward or outward relative to the paper.

[0064] In one embodiment, the angle adjustment module 320 further includes:

[0065] Multiple synchronous gears 324 are provided. When the worm gear 322 rotates, it drives the synchronous gears 324 to rotate. One of the synchronous gears 324 is provided with a scale.

[0066] The trigger element 325 is connected to the worm gear 322 and can trigger the worm gear 322 to rotate;

[0067] In this technology, the graduated synchronous gear is a dial, which allows the user to clearly know the rotation angle and the specific angle that is comfortable for them to wear, making it easy to adjust to the appropriate angle after wearing the joint fixation device for moderate osteoarthritis again.

[0068] Optionally, the graduated synchronous gear should be visible on the surface of the joint fixation device for osteoarthritis, or a viewing window should be provided to allow the user to observe the graduated synchronous gear, i.e., to easily observe the current rotation angle.

[0069] The trigger 325 assists in easily driving the worm gear 322 to rotate, such as Figure 1 As shown, the trigger element 325 is a fastener, as... Figure 3 As shown, the upper end of the worm gear 322 is connected to the trigger element 325 via a shaft; when it is necessary to drive the worm gear 322 to rotate via the trigger element 325, as... Figure 1 As shown in the angle adjustment module 320 located on the upper side of the joint fixation device for osteoarthritis, firstly, the trigger 325 is rotated to open, exposing the worm gear 323. Then, the trigger 325 is rotated, which drives the worm wheel 322 to rotate, thereby adjusting the rotation of the worm gear 323 and the synchronous gear 324, ultimately achieving the adjustment of the angle of the upper bracket 100.

[0070] Figure 1 The adjustment method of the angle adjustment module 320 located on the lower side of the joint fixator in osteoarthritis is the same as described above.

[0071] In one implementation, such as Figure 3 As shown, the activity module 310 includes:

[0072] The first connecting plate 311 has one end rotatably connected to an angle adjustment module 320, and the other end is provided with a bite tooth 313.

[0073] The second connecting plate 312 has one end rotatably connected to another angle adjustment module 320, and the other end is provided with a bite tooth 313;

[0074] The first connecting plate 311 and the second connecting plate 312 engage with each other via teeth 313;

[0075] The housing 314 covers the first connecting plate 311 and the second connecting plate 312.

[0076] When a user wears the joint fixation device for moderate osteoarthritis, the lower leg and thigh swing together while walking, and the upper support 100 and lower support 200 also swing relative to each other, making it more comfortable to wear.
