Description

Technical Field

[0001] This invention relates to the field of knee joint orthopedic devices, and more particularly to a flexible knee joint orthopedic medical assistive device. Background Technology

[0002] As an important weight-bearing joint in the human body, the knee joint often requires the use of orthotic devices for auxiliary treatment and rehabilitation training in cases of sports injuries, degenerative diseases, etc.

[0003] Most existing knee orthotic devices have a fixed structure and lack flexible angle adjustment capabilities. They cannot accurately adjust the orthotic angle of the knee joint according to different patient conditions and rehabilitation stages, making it difficult to meet personalized treatment needs. During patient rehabilitation training, traditional knee orthotic devices can usually only provide fixed support and restriction, and cannot assist patients in performing small-amplitude leg movements. Patients are in a fixed state for a long time, which is not conducive to blood circulation and muscle function recovery in the knee joint, thus prolonging the rehabilitation period. Therefore, we designed a flexible knee orthotic medical assistive device to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flexible knee joint orthopedic medical assistive device. This device can adjust the orthopedic angle as needed through an angle adjustment mechanism to meet different usage requirements. Through the combination of torsion springs and buffer springs, it can assist patients in small-amplitude leg movements.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A flexible knee joint orthotic medical assistive device includes a knee joint orthosis. A protective arc plate is fixedly connected to one side of the knee joint orthosis. Two ventilation holes are formed through the knee joint orthosis. A U-shaped plate is fixedly connected to the outer wall of the knee joint orthosis. A rotating rod is rotatably connected to the side wall of the knee joint orthosis, passing through and rotatably connected to the U-shaped plate. An angle adjustment mechanism is provided on the U-shaped plate. A hollow column is fixedly connected to the end of the rotating rod, and a rotating rod is rotatably connected to the inner wall of the hollow column. Two connecting plates are provided on one side of the knee joint orthosis, and the rotating rod passes through the upper connecting plate and... The device is fixedly connected, with the lower connecting plate fixedly connected to the side wall of the knee joint orthosis. A torsion spring is sleeved on the outer wall of the rotating rod, and the two ends of the torsion spring are fixedly connected to the inner wall of the hollow column and the side wall of the connecting plate, respectively. Two buffer springs are fixedly connected to the outer wall of the connecting plate, and both buffer springs are fixedly connected to the inner wall of the hollow column. Hollow plates are slidably connected to the outer walls of the two connecting plates. Each hollow plate is provided with a lifting mechanism. An arc-shaped plate is provided on one side of the connecting plate and the hollow plate. Two elastic bandages are fixedly connected to the outer wall of each arc-shaped plate, and each pair of elastic bandages is provided with an adhesive mechanism.

[0007] Preferably, the angle adjustment mechanism includes a worm gear that passes through and is rotatably connected to the U-shaped plate, a handle is fixedly connected to the end of the worm gear away from the U-shaped plate, and a worm wheel is fixedly connected to the outer wall of the rotating rod, with the worm gear meshing with the worm wheel.

[0008] Preferably, the lifting mechanism includes an anti-detachment block fixedly connected to the end of the connecting plate. The anti-detachment block is located inside the hollow plate and slidably connected to its inner wall. A sliding rod is fixedly connected to the inner wall of the hollow plate. The sliding rod passes through the anti-detachment block and is slidably connected to it. A threaded rod is rotatably connected to the hollow plate. The threaded rod passes through the anti-detachment block and is threadedly connected to it. A knob is fixedly connected to the end of the threaded rod away from the hollow plate.

[0009] Preferably, the hollow column has a through opening, and the connecting plate passes through the through opening and is slidably connected to its inner wall.

[0010] Preferably, the inner wall of the knee orthotic cover is provided with a protective layer, and the protective layer is made of silicone.

[0011] Preferably, the outer wall of the handle and the outer wall of the knob are both covered with protective sleeves, and the protective sleeves are made of rubber.

[0012] Preferably, the adhesive mechanism includes a first Velcro fastener fixedly connected to the side wall of one of the elastic bandages, and a second Velcro fastener fixedly connected to the side wall of the other elastic bandage, wherein the first Velcro fastener and the second Velcro fastener are adhesively connected.

[0013] Preferably, a first connecting block is fixedly connected to the side wall of the hollow plate, the first connecting block is fixedly connected to the side wall of its corresponding arc-shaped plate, and a second connecting block is fixedly connected to the side wall of the connecting plate, the second connecting block is fixedly connected to the side wall of its corresponding arc-shaped plate.

[0014] Compared with the prior art, the beneficial effects of this invention are as follows:

[0015] 1. Through the angle adjustment mechanism of the worm gear and worm wheel meshing, the staff can hold the handle to turn the worm gear, which will drive the rotating rod and other components to rotate, and precisely adjust the orthopedic angle at the knee joint. It can meet the personalized treatment needs according to the different conditions and rehabilitation stages of patients, and effectively improve the rehabilitation effect.

[0016] 2. The operator rotates the knob to drive the threaded rod to rotate, causing the anti-dislodgement block to slide inside the hollow plate. This adjusts the position of the connecting plate on the hollow plate and flexibly changes the distance between the two arc-shaped plates. This can accommodate the leg size of patients of different heights, ensuring a good fit between the device and the patient's leg. This not only improves the orthopedic effect but also enhances wearing comfort and avoids discomfort or injury caused by local pressure.

[0017] 3. When patients wear orthotic devices for rehabilitation training, small movements of the lower leg cause the hollow plate, connecting plate, and knee orthotic cover to swing. At this time, the connecting plate rotates around the rotating rod, simultaneously tightening or loosening the torsion spring and compressing or stretching the cushioning spring, assisting the patient's small-amplitude leg movements. This not only benefits blood circulation and muscle function recovery in the knee joint, shortening the rehabilitation period, but also provides cushioning and elastic potential energy assistance through the cushioning spring and torsion spring, making the movement process gentler and reducing the risk of secondary injury.

[0018] In summary, the present invention can adjust the orthopedic angle as needed through the angle adjustment mechanism to meet different usage needs; through the combination of the torsion spring and the buffer spring, it can assist the patient in small-amplitude leg movements.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Reference Figures 1-5 A flexible knee joint orthotic medical assistive device includes a knee joint orthotic cover 1. The inner wall of the knee joint orthotic cover 1 is provided with a protective layer made of silicone. The protective layer provides a soft contact surface for the patient's knee joint, reducing the pressure sensation when wearing it. A protective arc plate 2 is fixedly connected to one side of the knee joint orthotic cover 1. The protective arc plate 2 fits the knee joint, enhancing the overall structure's protection of the knee joint and ensuring wearing comfort. Two ventilation holes 3 are opened through the knee joint orthotic cover 1 to promote air circulation and prevent discomfort caused by stuffiness around the knee joint when wearing it.

[0027] A U-shaped plate 4 is fixedly connected to the outer wall of the knee orthosis 1. A rotating rod 5 is rotatably connected to the side wall of the knee orthosis 1. The rotating rod 5 passes through the U-shaped plate 4 and is rotatably connected to it. An angle adjustment mechanism is provided on the U-shaped plate 4. The angle adjustment mechanism includes a worm gear 6 that passes through the U-shaped plate 4 and is rotatably connected to it. A handle 7 is fixedly connected to the end of the worm gear 6 away from the U-shaped plate 4. A protective sleeve is provided on the outer wall of the handle 7. The protective sleeve is made of rubber. The protective sleeve increases the friction between the handle 7 and the hand to prevent slippage during operation. A worm wheel 8 is fixedly connected to the outer wall of the rotating rod 5. The worm gear 6 meshes with the worm wheel 8. The self-locking property of the worm wheel and worm gear ensures the stability after angle adjustment. The rotation of the worm gear 6 is converted into the rotation of the rotating rod 5 to achieve angle adjustment.

[0028] A hollow column 9 is fixedly connected to the end of the rotating rod 5. A rotating rod 12 is rotatably connected to the inner wall of the hollow column 9. The rotating rod 12 provides a rotation center for the connecting plate 11, allowing the connecting plate 11 to rotate around it. Two connecting plates 11 are provided on one side of the knee joint orthosis 1. The rotating rod 12 passes through the upper connecting plate 11 and is fixedly connected to it. A through-hole 10 is provided on the hollow column 9. The connecting plate 11 passes through the through-hole 10 and abuts against its inner wall. The through-hole 10 restricts the movement trajectory of the connecting plate 11, allowing it to swing within a specific range. The lower connecting... The connecting plate 11 is fixedly connected to the side wall of the knee joint orthosis 1. The outer wall of the rotating rod 12 is fitted with a torsion spring 13. The two ends of the torsion spring 13 are fixedly connected to the inner wall of the hollow column 9 and the side wall of the connecting plate 11, respectively. The torsion spring 13 stores and releases elastic potential energy when the connecting plate 11 swings, assisting the leg to move in a small range. Two buffer springs 14 are fixedly connected to the outer wall of the connecting plate 11. Both buffer springs 14 are fixedly connected to the inner wall of the hollow column 9. The buffer springs 14 provide buffering force to reduce the impact during movement when the connecting plate 11 swings.

[0029] Both connecting plates 11 have hollow plates 16 slidably connected to their outer walls. The hollow plates 16 provide installation space for the lifting mechanism and cooperate with the connecting plates 11 to adjust the spacing. Each hollow plate 16 is equipped with a lifting mechanism, which includes an anti-detachment block 15 fixedly connected to the end of the connecting plate 11. The anti-detachment block 15 is located inside the hollow plate 16 and slidably connected to its inner wall. The anti-detachment block 15 prevents the connecting plate 11 from detaching from the hollow plate 16 and, in conjunction with the lifting mechanism, enables the sliding adjustment of the connecting plate 11. The inner wall of the hollow plate 16 is fixedly connected... A sliding rod 17 is connected to the anti-detachment block 15 and is slidably connected to it. A threaded rod 18 is rotatably connected to the hollow plate 16 and is rotatably connected to it. The threaded rod 18 is rotatably connected to the anti-detachment block 15 and is threaded to it. The threaded rod 18 converts the rotation of the knob 19 into the linear motion of the anti-detachment block 15, thereby realizing the lifting and lowering adjustment of the connecting plate 11. The end of the threaded rod 18 away from the hollow plate 16 is fixedly connected to the knob 19. The outer wall of the knob 19 is covered with a protective sleeve made of rubber. The protective sleeve increases the friction between the knob 19 and the hand, making it easier to apply force.

[0030] Both the connecting plate 11 and the hollow plate 16 have an arc-shaped plate 21 on one side. The arc-shaped plate 21 fits against the patient's leg to provide support and fixation. A first connecting block 20 is fixedly connected to the side wall of the hollow plate 16. The first connecting block 20 is fixedly connected to the side wall of its corresponding arc-shaped plate 21. A second connecting block 25 is fixedly connected to the side wall of the connecting plate 11. The second connecting block 25 is fixedly connected to the side wall of its corresponding arc-shaped plate 21. Two elastic bandages 22 are fixedly connected to the outer wall of each arc-shaped plate 21. The elastic bandages 22 use their own elasticity to tightly fix the arc-shaped plate 21 to the patient's leg. Each pair of elastic bandages 22 is provided with an adhesive mechanism. The adhesive mechanism includes a first Velcro 23 fixedly connected to the side wall of one of the elastic bandages 22, and a second Velcro 24 fixedly connected to the side wall of the other elastic bandage 22. The first Velcro 23 and the second Velcro 24 are adhesively connected. The first Velcro 23 and the second Velcro 24 are adhesively connected to achieve quick fixation and removal of the elastic bandages 22.

[0031] In this invention, when orthopedic treatment of a patient's knee joint, the patient wears the knee orthotic cover 1 on their knee joint, with one side of the leg close to the arc-shaped plate 21. The arc-shaped plate 21 is secured to the patient's leg using two elastic bandages 22, a first Velcro strap 23, and a second Velcro strap 24, thereby orthopedic treatment of the patient's knee joint. The operator can pre-grip the knob 19 to rotate the threaded rod 18, causing the anti-slip block 15 to slide within the hollow plate 16, which in turn adjusts the sliding of the connecting plate 11 on the hollow plate 16, thus adjusting the distance between the two arc-shaped plates 21. This allows for use by patients of different heights (and leg lengths). During orthopedic treatment, this device can assist the patient... With slight leg movements, the patient's lower leg moves slightly, causing the hollow plate 16, connecting plate 11, and knee orthotic cover 1 to swing. At this time, the connecting plate 11 rotates around the rotating rod 12 (the connecting plate 11 moves within the opening 10), and simultaneously drives the torsion spring 13 to store or release energy, while also driving the buffer spring 14 to compress or stretch. This allows the wearer to move slightly, increasing comfort. When the wearer needs to adjust the orthotic angle at the knee joint, the staff holds the handle 7 and rotates it, causing the worm gear 6, worm wheel 8, rotating rod 5, hollow column 9, upper connecting plate 11, and hollow plate 16 to rotate. The angle at the knee joint can be adjusted according to the patient's needs to meet different usage requirements.

[0032] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
