Description

Technical Field

[0001] The utility model relates to the technical field of medical rehabilitation equipment, in particular to a lower limb skeletal movement rehabilitation device. Background Art

[0002] Lower limb skeletal injuries are a common clinical orthopedic problem, often caused by traffic accidents, sports injuries, and age-related bone degeneration. Rehabilitation training after lower limb fractures, ligament injuries, and joint replacement surgery is crucial for patients to regain their ability to walk and improve their quality of life. During the rehabilitation process, scientific lower limb functional recovery training helps restore muscle strength, improve joint mobility, promote fracture healing, and avoid complications such as muscle atrophy and joint stiffness caused by prolonged bed rest.

[0003] In order to improve the rehabilitation effect, patients usually need to perform daily walking outside the bed to achieve effective exercise for the bones. However, conventional walking mainly focuses on the strength of bones and muscles in the front-to-back direction, and it is usually difficult to get enough exercise for the bones and muscles that move sideways. Especially in the rehabilitation process after hip and knee injuries, neglecting the training of lateral strength may lead to decreased joint stability, muscle strength imbalance, and even delay the progress of rehabilitation. Existing rehabilitation equipment mostly focuses on the front-to-back direction movement, such as walking machines, steppers, etc., and rarely involves specialized training for the lateral strength of the lower limbs, resulting in insufficient recovery of the lateral muscles and bones. This may cause patients to suffer secondary injuries due to instability in daily life, especially in lateral movements such as turning, walking sideways, etc., the disadvantage of insufficient lateral strength is particularly obvious. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a lower limb skeletal exercise rehabilitation device.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present utility model is as follows:

[0006] The lifting of the lifting device is to lift the lifting device up and down, and the lifting of the lifting device is to lift the lifting device up and down, so that the lifting device can be lifted and lowered into the lifting position according to the lifting of the lifting device.

[0007] Furthermore, any one of the elastic components includes two longitudinally arranged springs, the two ends of which are fixedly connected to the inner side wall of the transverse guide groove and the slider, respectively. The elastic component provides a buffering and rebound effect for the slider, ensuring that it can always return to the middle position during the patient's leg transverse exercise, thereby increasing the functional scenario of the patient's horizontal exercise. In addition, when the patient performs circular motions of the lower limbs, the elastic changes of the elastic component can enable the patient to feel force feedback in different directions, thereby increasing the strength training of footstep control. The elastic component can also be used to make the force applied by the patient generate a corresponding reaction force, helping the patient to perform more stable exercise training.

[0008] Furthermore, a control groove is provided at the top of the transverse guide groove and arranged along the long side of the transverse guide groove, and the control groove is connected to the slideway of the transverse guide groove.

[0009] Furthermore, a screw hole is provided on the side of the slider facing the control slot, and a second tightening bolt passing through the control slot is provided on the screw hole. According to the use requirements, the patient can lock or release the free movement of the slider by adjusting the second tightening bolt. After locking, the slider is fixed in the center of the control slot, and only circular motion of the lower limbs is performed. After unlocking, the patient can perform lateral leg exercises by exerting force laterally, and perform more personalized training or local strengthening training during the circular motion to meet the needs of different patients at different stages of rehabilitation.

[0010] Furthermore, the adjustable bracket includes a sleeve portion and a movable portion. The sleeve portion is mounted on the fixed bracket, and the movable portion is movably and telescopically connected to the sleeve portion. The adjustable bracket can be adjusted in length through the telescopic connection design of the sleeve portion and the movable portion. Patients can flexibly adjust the overall height based on leg length, rehabilitation needs, and training posture, ensuring that the lower limb is at the optimal angle and position during rotation training, thereby increasing the adaptability of the device.

[0011] Furthermore, a guide rail is provided around the inner circumference of the annular hole, and a groove is provided around the sidewall of the rotating disk. The groove is adapted to engage with the guide rail. The engagement between the guide rail and the groove ensures that the rotating disk remains stable during rotation, preventing shaking or deviation, ensuring smooth and accurate movement and enhancing the effectiveness of rehabilitation training.

[0012] Furthermore, a display board with an electronic tablet is mounted on the top of the fixed bracket. Patients can view their exercise data in real time during lower limb skeletal exercise rehabilitation training. Medical staff can also monitor the patient's training results and make corresponding adjustments based on parameters such as the rotating disk's speed and number of revolutions.

[0013] Furthermore, the rotating disk is equipped with sensors and a data acquisition module, which are connected to an electronic tablet. These sensors and data acquisition modules are installed on the rotating disk and monitor the number of rotations and speed of the rotating disk in real time. The data acquisition module transmits these values ​​to a data processing module on the electronic tablet via a wireless transmission module, which then displays the movement status in real time on an electronic screen. The electronic screen displays data such as rotation angle, force change, speed, and other movement parameters through a pre-set application.

[0033] Example 2

[0034] Based on the first embodiment, this embodiment proposes a specific implementation process of a lower limb skeletal exercise rehabilitation device.

[0035] The specific implementation principle process is as follows:

[0036] First, the patient adjusts the length of the adjustable bracket 5 according to their height and leg length, ensuring that their lower limbs can rest on the footrest 12 during use. Next, according to their training plan and comfort level, they rotate the first jacking bolt 4 to adjust the inclination of the adjustable bracket 5, so that its forward and backward tilt meets the needs of rehabilitation and training. During rehabilitation training, the footrest 12 can be locked, that is, the second jacking bolt 14 is secured. At this point, the patient can perform lateral force exercises on their legs. The spring of the elastic component 11 provides a cushioning and rebound effect, increasing the resistance of the exercise while also ensuring that the footrest 12 always returns to the center position. When the patient's lower limb performs circular motions, the second jacking bolt 14 can be used to lock the footrest 12 to ensure relative stability. Based on the data displayed on the electronic tablet 17, the patient or medical staff can adjust the training intensity. For example, if the exercise angle is too small or the force is insufficient, the medical staff can adjust the elasticity of the elastic component 11 to increase or decrease the resistance of the slider 10. Adjusting the inclination angle of the bracket 5 can also change the difficulty of the exercise and the direction of force, ensuring optimal training results.

[0037] Of course, the present invention may have many other implementation methods. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
