Description

Technical Field

[0001] The present invention relates to the field of walking assist devices, and in particular to a walking assist device for orthopedic rehabilitation. Background Art

[0002] Orthopedic rehabilitation is a highly comprehensive and sophisticated medical process. It is committed to effectively alleviating the limb dysfunction of orthopedic patients, accelerating the full recovery of their body functions, and helping them return to normal social life as soon as possible and with higher quality through the careful planning and coordinated use of a series of diversified medical intervention measures. This rehabilitation concept encompasses professional methods in multiple fields such as physical therapy, exercise therapy, and medical engineering, and each link is aimed at promoting the patient's physical and psychological recovery.

[0003] Specifically, the core content of orthopedic rehabilitation is broad and in-depth, covering the following key aspects: Strength training: As the cornerstone of the rehabilitation program, strength training uses targeted exercises to strengthen the damaged area and surrounding muscles, which is essential for stabilizing joints and improving movement efficiency. The training methods are diverse, ranging from simple isometric contractions to complex dynamic resistance exercises, aiming to gradually restore the patient's muscle strength and endurance.

[0004] Joint function training: This part focuses on improving the range of motion and flexibility of the joints. Through gentle joint movements, stretching exercises, and joint mobilization, it reduces adhesion and stiffness, promotes the secretion of synovial fluid, and thus improves the joint's movement function.

[0005] Joint proprioception and balance function training: Proprioception refers to the body's ability to perceive its own position and movement state, which is essential for maintaining body balance. Through balance board exercises, single-leg standing and other training, the patient's proprioception can be enhanced, their balance ability in different environments can be improved, and the risk of falling can be reduced.

[0006] Gait training: For patients with impaired walking ability, gait training aims to optimize walking patterns by adjusting parameters such as step length, speed, and step width, reduce the extra burden caused by abnormal gait, and promote natural and smooth walking.

[0007] Rehabilitation treatment of neurological function: For patients whose nervous system functions are affected by orthopedic diseases or trauma, such as spinal cord injury, peripheral nerve injury, etc., advanced technologies such as neural remodeling training, electrical stimulation therapy, and biofeedback are used to promote nerve regeneration and functional recovery.

[0008] Application of prostheses and orthoses: For patients with functional impairment caused by limb loss or severe deformities, customized prostheses and orthoses can effectively replace or compensate for the missing functions and improve patients' daily self-care ability and quality of life.

[0009] In order to implement the above rehabilitation measures more effectively, the application of rehabilitation equipment is indispensable. From simple elastic bands and dumbbells to complex treadmills, balance training equipment, and even high-tech rehabilitation robots and virtual reality training systems, these equipment not only provide strong support for rehabilitation training, but also greatly enrich the training form, improve the fun and effectiveness of training, and promote the dual improvement of patient participation and rehabilitation effect.

[0010] In summary, orthopedic rehabilitation is an all-round, multi-level treatment process, which requires the medical team to have a high degree of professional knowledge and humanistic care, and to jointly push patients towards comprehensive recovery through accurate assessment, personalized planning, scientific training, and timely introduction of advanced rehabilitation technology and equipment.

[0011] Existing walking assist devices are mainly brackets welded or assembled from steel, such as the walking assist device disclosed in the Chinese patent with patent application number "CN202210311317.1". When in use, the patient needs to use the strength of the upper arms to support the entire body. When walking, the walking assist device needs to be moved forward one step, and then the whole body is supported by the supporting force of the upper limbs, and then the lower limbs are moved to the walking assist device. The upper limb strength requirements are relatively high, and it is inconvenient for patients with weak upper limb strength to perform rehabilitation training. Therefore, how to reduce the upper limb strength requirements for patients so as to achieve the purpose of rehabilitation training for patients' lower limbs.

[0012] In order to solve the above problems, the present application proposes a walking assist device for orthopedic rehabilitation. Summary of the invention

[0024] The above technical solution of the present invention has the following beneficial technical effects: The distance between the support rods is adjusted according to the height and physique, and the telescopic rods are adjusted to the height to suit the height. The laying rods support the underarms instead of the active support of the artificial arms, thereby reducing the consumption of manpower. When the lower limbs are not exercised, the weight of the human body acts on the spring through the laying rods to compress the spring. The laying rods move downward to rotate through the rack and the turntable, and under the action of the damping shaft, they slowly descend and respond at the same time, which serves as a reminder to move downward, so that the user is mentally prepared and the downward movement of the sleeve , driving the moving tube to move downward so that the support rod is supported by the ground, thereby achieving contact with the ground, so as to limit the position of the entire device, so that it is limited when the legs are not exercising, thereby increasing the safety of use. When the legs apply force to exercise walking, the legs act on the ground, and the body moves up to support the body. At this time, the force exerted on the spring is reduced, so as to drive the mounting rod to move up with the body, thereby self-adaptively assisting walking. When the legs walk, the support rod is accompanied by the reduction of the effect of the human body weight, and the contact with the ground is released to release the limit on the entire device, thereby achieving the effect of adaptive use.
