Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a rehabilitation assistive frame for lumbar spine surgery. Background Technology

[0002] The lumbar spine is an important part of the human spine. Its main functions are to support the weight of the upper body, participate in the flexion, extension and lateral bending movements of the lower trunk and pelvis, and protect the spinal cord and cauda equina. Therefore, the lumbar spine often develops symptoms such as protrusion and scoliosis due to poor posture or trauma. In severe cases, surgery is required. After surgery, a rehabilitation brace is needed to assist the lumbar spine in supporting the body and help with the recovery of the lumbar spine.

[0003] Existing rehabilitation braces typically support the lumbar region by fixing it to the waist, restricting lumbar flexion and other movements. Some also add leg support, transferring upper body weight to the legs, greatly reducing the difficulty of movement and accelerating the traditional rehabilitation training process. However, after surgery, patients need to stay in bed from the first day and perform leg rehabilitation exercises while in bed. Leg flexion and extension movements increase blood circulation and muscle strength, accelerating the recovery process. However, many patients are afraid to move due to pain and discomfort after lumbar spine surgery. The aforementioned rehabilitation braces cannot assist patients in performing leg flexion and extension movements. Therefore, to address these issues, we propose a rehabilitation assistive activity brace for lumbar spine surgery. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a rehabilitation support frame for lumbar spine surgery. In the early postoperative period, it assists patients in performing leg flexion and extension exercises. While transferring the weight of the upper body to the legs, it can assist patients in performing leg flexion and extension exercises, increase blood circulation and muscle strength in the legs, and accelerate the recovery process of the lumbar spine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rehabilitation assistive activity frame for lumbar spine surgery, comprising a frame body, connecting parts, and leg fixation components. The frame body includes a front support part and a rear support part. The rear support part is provided with a connecting strap, which is connected to the front support plate via a connecting component. There are two connecting parts, which are symmetrically and detachably connected to the lower end of the frame body. A telescopic component is hinged to the bottom of the connecting part, and a locking component is provided between the telescopic component and the connecting part. A connecting plate is hinged to the bottom of the telescopic component. The leg fixation component is connected to the telescopic component, and an elastic sleeve is provided at the bottom of the leg fixation component. The bottom of the elastic sleeve is connected to the connecting plate. A training component is provided between the leg fixation component and the elastic sleeve.

[0006] The beneficial effects of this utility model are as follows: by supporting the patient's waist with the front support and the rear support, and then fixing the leg fixation piece to the thigh and the elastic sleeve to the calf, when the patient lies down to perform leg flexion and extension exercises, the training component causes the leg fixation piece and the elastic sleeve to bend, thereby driving the thigh and calf to perform flexion and extension movements, increasing blood circulation and muscle strength in the legs, and accelerating the recovery process of the lumbar spine.

[0007] To facilitate adjustments based on the individual patient's condition;

[0008] As a further improvement to the above technical solution: the training component includes a support plate connected to the lower end of the elastic sleeve, two retaining rings respectively disposed on the support plate and the leg fixing member, and a spring detachably connected between the two retaining rings.

[0009] The beneficial effects of this improvement are as follows: The elastic sleeve is worn on the patient's lower leg, and multiple springs are connected between the two retaining rings according to the patient's leg condition. When the springs recover their deformation, they pull the lower leg towards the thigh, causing flexion between the thigh and the lower leg. After the leg is bent, the patient's leg will straighten spontaneously under the action of gravity, and the springs will be stretched and deformed. When the leg is straightened, it will naturally relax. At this time, the springs will gradually recover their deformation and then drive the leg to bend again, thereby assisting the patient in performing leg flexion and extension movements and increasing blood circulation in the legs.

[0010] To facilitate the assembly and disassembly of the connecting parts;

[0011] As a further improvement to the above technical solution: the connecting part is provided with a mounting plate, and the two ends of the mounting plate are connected to the front support part and the rear support part respectively by screws.

[0012] The beneficial effects of this improvement are: by disassembling and assembling the connecting part, the entire part below the support body can be disassembled. When the patient is in the late stage of rehabilitation, the lumbar spine is in a state of near full recovery. At this time, the connecting part can be removed, which makes it easier for the patient to move around and increases the convenience of daily life.

[0013] To accommodate the different thigh needs of patients;

[0014] As a further improvement to the above technical solution: the telescopic component includes an outer rod hinged to the bottom of the connecting part and an inner rod slidably connected to the inside of the outer rod. A screw is threaded onto the outer rod, and one end of the screw extends into the inside of the outer rod.

[0015] The beneficial effects of this improvement are as follows: Different patients have different thigh lengths, so the screw rod can be loosened according to the patient's leg condition to release the inner rod from locking, and then pulled outwards from the outer tube. After the leg fixing part moves to the appropriate position, the screw rod is tightened, and the screw rod abuts against the inner rod to fix the inner rod.

[0016] To enable flexible use;

[0017] As a further improvement to the above technical solution: the locking member includes a second screw, which is threadedly connected to the connecting part and used to fix the telescopic member.

[0018] The beneficial effects of this improvement are as follows: When the patient is lying in bed and performing leg flexion and extension exercises, the second screw is loosened to facilitate the patient's leg flexion and extension. At this time, the second screw releases the lock on the telescopic component, and the thigh can also move easily when the thigh and calf are flexed and extended. When the patient stands up and walks, the second screw is tightened, and one end of the second screw abuts against the telescopic component to fix the telescopic component. At this time, the leg fixation component is positioned, thereby concentrating the power of the upper body on the legs and reducing the pressure on the upper body.

[0019] To facilitate leg fixation;

[0020] As a further improvement to the above technical solution: the leg fixing component includes an arc-shaped leg plate and an adjustment belt connected to the arc-shaped leg plate. The adjustment belt and the arc-shaped leg plate are connected by a connector. The arc-shaped leg plate has a flexible pad inside.

[0021] The beneficial effects of this improvement are as follows: when the legs need to be fixed, the patient's legs are placed on the curved leg board, and then the connection between the adjusting belt and the curved leg board is adjusted and fixed to keep the legs and upper body in a straight line, providing support for the lumbar spine. In addition, the flexible pad increases the patient's comfort and avoids pressure sores on the legs.

[0022] To increase patient comfort;

[0023] As a further improvement to the above technical solution: the lower end of the rear support is provided with a waist support, and the inner surfaces of the front support and the rear support are both provided with protective pads, and the protective pads and the waist support are both made of flexible materials.

[0024] The beneficial effects of this improvement are: the lumbar support is designed to adapt to the physiological curve of the lumbar spine, providing support for the lumbar spine; and the flexible material increases patient comfort and avoids damage to the patient's skin from an overly rigid support body.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0032] like Figure 1-5 As shown, a lumbar spine postoperative rehabilitation assistive activity frame includes a frame body 1, connecting parts 4, and leg fixation components. The frame body 1 includes a front support part 101 and a rear support part 102. The rear support part 102 is provided with a connecting strap 2, which is connected to the front support plate 901 by a connecting member 3. There are two connecting parts 4, which are symmetrically and detachably connected to the lower end of the frame body 1. A telescopic member is hinged to the bottom of the connecting part 4, and a locking member is provided between the telescopic member and the connecting part 4. A connecting plate 7 is hinged to the bottom of the telescopic member. The leg fixation component is connected to the telescopic member. An elastic sleeve 10 is provided at the bottom of the leg fixation component, and the bottom of the elastic sleeve 10 is connected to the connecting plate 7. A training component is provided between the leg fixation component and the elastic sleeve 10.

[0033] Specifically, the front support 101 is fitted to the front chest and abdomen, and the rear support 102 is fitted to the back. The connecting strap 2 is connected to the front support 101 by a connector, which can be Velcro. The structure includes a snap fastener, which confines the waist within the support body 1. The two leg fixation pieces are then moved to appropriate positions by adjusting the telescopic components and secured to the thighs on both sides. The elastic sleeve 10 is then fitted onto the lower legs. When the patient needs to stand and walk, the locking component locks the telescopic components, ensuring they are vertical and fixed to the connecting part 4. All pressure is transferred to the legs, reducing pressure on the upper body. When the patient needs to lie down, the locking component releases the telescopic components, allowing them to rotate. The training component then moves the elastic sleeve 10 and the leg fixation pieces, causing flexion and extension movements of the thighs and lower legs. Simultaneously, the telescopic components hinge with the connecting plate 7, assisting the patient in leg flexion and extension movements. This transfers upper body weight to the legs, increasing blood circulation and muscle strength, and accelerating lumbar spine rehabilitation.

[0034] Preferably, the training component includes a support plate 901 connected to the lower end of the elastic sleeve 10, two retaining rings 902 respectively disposed on the support plate 901 and the leg fixation member, and a spring 903 detachably connected between the two retaining rings 902. The elastic sleeve 10 is worn on the patient's lower leg, and then multiple springs 903 are connected between the two retaining rings 902 according to the patient's leg condition. When the springs 903 recover their deformation, they can pull the lower leg towards the thigh, causing flexion between the thigh and the lower leg. After the leg is bent, the patient's leg will straighten under the action of gravity, and the springs 903 will be stretched and deformed. When the leg is straightened, it will naturally relax. At this time, the springs 903 will gradually recover their deformation and then drive the leg to bend, thereby assisting the patient in performing leg flexion and extension exercises and increasing blood circulation in the legs.

[0035] Preferably, the connecting part 4 is provided with a mounting plate 11. The two ends of the mounting plate 11 are connected to the front support part 101 and the rear support part 102 respectively by screws 12. By disassembling and assembling the connecting part 4, all parts below the bracket body 1 can be disassembled. When the patient is in the late stage of rehabilitation, the lumbar spine is in a state of near-complete recovery. At this time, the connecting part 4 can be removed, which makes it easier for the patient to move around and increases the convenience of daily life.

[0036] Preferably, the telescopic component includes an outer rod 501 hinged to the bottom of the connecting part 4 and an inner rod 502 slidably connected to the interior of the outer rod 501. A screw 13 is threaded onto the outer rod 501, and one end of the screw 13 extends into the interior of the outer rod 501. Since the length of the thighs of different patients is different, the screw 13 can be loosened according to the patient's leg condition to release the inner rod 502 from locking, and then pulled outward from the outer tube. After the leg fixation component moves to the appropriate position, the screw 13 is tightened, and the screw 13 abuts against the inner rod 502 to fix the inner rod 502. The position of the leg fixation component can also be changed at any time to prevent pressure sores on the legs.

[0037] Preferably, the locking component includes a second screw 6, which is threadedly connected to the connecting part 4 and used to fix the telescopic component. When the patient is lying in bed and performing leg flexion and extension exercises, the screw 6 is loosened to facilitate leg flexion and extension. At this time, the screw 6 releases the locking of the telescopic component, and the thigh can also move easily when the thigh and calf flex and extend. When the patient stands up and walks, the screw 6 is tightened, and one end of the screw 6 abuts against the telescopic component to fix it. At this time, the leg fixing component is positioned, thereby concentrating the power of the upper body on the legs and reducing the pressure on the upper body.

[0038] Preferably, the leg fixation component includes an arc-shaped leg plate 801 and an adjustment strap 802 connected to the arc-shaped leg plate 801. The adjustment strap 802 and the arc-shaped leg plate 801 are connected by a connector 14. The arc-shaped leg plate 801 has a flexible pad 17 inside, which can be made of materials such as sponge or memory foam. The connector 14 can be a Velcro or snap fastener. When the legs need to be fixed, the patient places both legs on the arc-shaped leg plate 801, and then adjusts and fixes them by the connector 14 between the adjustment strap 802 and the arc-shaped leg plate 801, so that the legs and the upper body are in a straight line, providing support for the lumbar spine.

[0039] Preferably, the lower end of the rear support portion 102 is provided with a lumbar support 15, and the inner surfaces of the front support portion 101 and the rear support portion 102 are provided with protective pads 16. Both the protective pads 16 and the lumbar support 15 are made of flexible materials, such as sponge or memory foam. The lumbar support 15 is designed to adapt to the physiological curve of the lumbar spine and support the lumbar spine. The flexible material increases the patient's comfort and avoids damage to the patient's skin caused by the excessive rigidity of the bracket body 1.

[0040] The working principle and usage process of this utility model are as follows: When using this device, firstly, install the mounting plate 11 on the lower end of the bracket body 1 using screws 12. Then, fit the front support part 101 against the front chest and abdomen, and then fit the rear support part 102 against the back. Connect the connecting strap 2 to the front support part 101 using a connector. At this time, the lumbar support 15 supports the curved part of the lumbar spine. Then, the protective pad 16 increases the patient's comfort. Then, by loosening the screw 13, release the resistance to the inner rod 502 and pull the inner rod 502 out of the outer rod 501. Move the two leg fixing parts to the appropriate position and place the thighs on both sides inside the arc-shaped leg plate 801. The flexible pad 17 increases the patient's comfort. Then, the adjusting strap 802 is connected to the arc-shaped leg plate 801 through the connector 14. The lower leg is inserted into the elastic sleeve 10. When the patient is lying on the bed, loosen the screw 13. Screw 26 is used to release the telescopic component. Then, a suitable number of springs 903 are installed on the two retaining rings 902, ensuring that the number of springs 903 is sufficient to bend the thigh and calf. When the patient's legs are straightened, the springs 903 will pull the leg fixation component and support plate 901 when they return to their original shape in a relaxed state, thus pulling the thigh and calf into a bend. The patient can then straighten their legs under their own weight. When the legs are in a natural relaxed state, they will bend again. When the patient gets out of bed and walks, screw 26 is tightened, the springs 903 are removed, and the leg fixation component is fixed, thereby transferring the pressure of the upper body to the legs, reducing the pressure on the lumbar spine. While transferring the weight of the upper body to the legs, it can assist the patient in performing leg flexion and extension movements, increasing blood circulation and muscle strength in the legs, and accelerating the recovery process of the lumbar spine.
