Technical Field
[0001] This utility model relates to the field of medical rehabilitation training technology, and in particular to a gait training support frame for postoperative rehabilitation in orthopedic surgery. Background Technology
[0002] When performing gait training for post-operative rehabilitation in orthopedic surgery, a gait training support frame is often used. This is an assistive device that offers numerous benefits, such as helping patients gradually regain a normal gait after surgery, reducing the risk of falls by providing stable support, enhancing patients' confidence when walking, assisting in the recovery and exercise of muscle strength, and effectively promoting the rehabilitation process of physical function after orthopedic surgery. It is precisely because of these important roles in patient rehabilitation that this gait training support frame is used in the post-operative rehabilitation stage of orthopedic surgery.
[0003] A gait training support frame for post-orthopedic surgery rehabilitation is appropriately adjusted based on the patient's specific circumstances (such as height, body type, surgical site, and recovery stage) to ensure accurate and comfortable support. Next, under the guidance of medical staff or a rehabilitation therapist, the patient grips the support frame's handrails and leans their body weight appropriately against it for stable support. Then, following the steps outlined in the rehabilitation plan, the patient begins walking training with small steps and a slow pace. During walking, the support frame continuously provides support and balance, helping the patient maintain correct posture and reducing stress on the injured area. As the patient's rehabilitation progresses, the training intensity and walking method are gradually adjusted until the patient can walk more freely, ultimately achieving the rehabilitation goal and completing the transition from using the support frame to independent walking.
[0004] Existing technologies for gait training support devices in post-operative rehabilitation of orthopedic surgeons often lack flexibility in design. Many traditional gait training support frames have fixed widths and spacings, making them unadjustable to individual patient differences. Different patients vary significantly in height, body type, and surgical site. For example, tall and wide patients have drastically different needs for support frame widths and spacing compared to petite patients. Fixed-width support frames cause wider patients to feel cramped, preventing them from naturally and comfortably placing their feet, thus affecting training effectiveness and even increasing the risk of falls due to awkward posture. Conversely, for petite patients, excessively wide spacing makes it difficult to provide precise and effective support, hindering proper force transmission and gait training. Therefore, this paper proposes a gait training support frame for post-operative rehabilitation of orthopedic surgeons to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a gait training support frame for postoperative rehabilitation in orthopedic surgery, aiming to improve the problem that some existing devices cannot adjust the width and spacing of the gait training support frame.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1 to 2 This utility model provides an embodiment of a gait training support frame for post-orthopedic rehabilitation, including a rehabilitation gait shell 1, which is the main body of the entire gait training support frame to ensure stability and durability during use. A button 2 is fixedly connected to the outside of the rehabilitation gait shell 1. The operation button 2 located outside the rehabilitation gait shell 1 is used to control various functions of the support frame, such as adjusting the width, starting or stopping the motor 3, etc. The outside of the rehabilitation gait shell 1 is provided with a width adjustment mechanism, which includes a series of interconnected components for adjusting the width of the support frame to adapt to different patient body shapes. The outside of the rehabilitation gait shell 1 is provided with an anti-fall mechanism, a safety feature, to prevent patients from accidentally falling when using the support frame, so as to ensure that patients remain stable during walking.
[0034] The width adjustment mechanism includes a rehabilitation gait housing 1. An adjustment component for providing the width of the rehabilitation gait training support frame is fixedly connected inside the rehabilitation gait housing 1. A connecting rod 4, a rotatable rod, is rotatably connected to the outside of the adjustment component and connected to a motor 3 to transmit power and drive the width adjustment mechanism. Follower rods 5 are rotatably connected to the front and rear sides of the connecting rod 4. The follower rods move with the rotation of the connecting rod 4 to help adjust the width of the support frame. A fixing plate 6 is rotatably connected to the outside of the follower rod 5 to fix and support the plates of other components.
[0035] The external fixed connection of the fixation plate 16 is a sliding base 7, a base that slides on the fixation rod 8, used to support the fixation plate 3 10 and the axillary support rod 11. The internal sliding connection of the sliding base 7 is the fixation rod 8, ensuring that it has sufficient strength and stability to withstand the patient's weight and other external forces. Fixation plates 2 9 are fixedly connected to the front and rear sides of the fixation rod 8. The top of the sliding base 7 is fixedly connected to the fixation plate 3 10, a plate located at the top of the sliding base 7, used to fix the axillary support rod 11. The design of the fixation plate 3 10 should ensure that it can firmly fix the axillary support rod 11 without causing discomfort or injury to the patient.
[0036] Axillary support rods 11 are fixedly connected to both the left and right sides of the fixed plate 3 10. A pair of rods located on both sides of the fixed plate 3 10 are used to support the patient's underarm area. The design of the axillary support rods 11 should conform to ergonomic principles so that the patient feels comfortable and supported when using it. The adjustment component includes a motor 3, which is externally fixedly connected to the inside of the rehabilitation gait shell 1, and the connecting rod 4 is externally rotatably connected to the outside of the motor 3.
[0037] Reference Figures 2 to 3 The fall-prevention mechanism includes a slide rail 12. To provide a stable track for the smooth movement of the sliding block 15, a groove 13 is fixedly connected inside the slide rail 12. A recess inside the slide rail 12 accommodates a limiting block 14 and the sliding block 15. The groove 13 is designed to ensure that the sliding block 15 can slide smoothly within it, while the limiting block 14 effectively restricts the range of movement of the sliding block 15. The limiting block 14, a block-like object fixed inside the groove 13, is fixedly connected inside to restrict the range of movement of the sliding block 15. The position of the limiting block 14 can be adjusted as needed to ensure that the sliding block 15 stops moving at the appropriate position, thereby preventing the patient from falling during use.
[0038] The slide rail 12 is externally fixed to the outside of the axillary support bar 11. A sliding block 15, a block-shaped object that slides within the slide groove 13, is slidably connected inside the slide groove 13. Through its connection with the slide rail 16, it transfers the patient's weight to the support frame. The sliding block 15 is designed to ensure smooth sliding within the slide groove 13 and to withstand the patient's weight. The slide rail 16 is externally fixed to the sliding block 15 to further distribute the patient's weight and provide additional stability. An outlet 17, an opening, is internally fixed to the slide groove 13 to allow the sliding block 15 to enter or exit the slide groove 13.
[0039] The design of the slide rail outlet 17 should ensure its appropriate size, allowing the sliding block 15 to pass smoothly while preventing excessive external force from causing the sliding block 15 to fall off. An extension spring 18, an elastic element, is fixedly connected to the outside of the slide rail 16. The function of the extension spring 18 is to provide resistance when the sliding block 15 moves, thereby increasing the stability of the entire anti-fall mechanism. When the patient's weight is applied to the support frame, the extension spring 18 is compressed, thereby absorbing some of the impact force and reducing pressure on the patient's body.
[0040] Reference Figures 3 to 4 An extension spring 18 is externally fixedly connected to a connecting block 19, an intermediate connector used to connect the extension spring 18 to the fall arrestor belt 20. The connecting block 19 is designed to ensure it is securely fixed between the extension spring 18 and the fall arrestor belt 20 without causing discomfort or injury to the patient. The fall arrestor belt 20, a safety belt used to prevent the patient from falling during use, is externally fixedly connected to the connecting block 19. The fall arrestor belt 20 is typically made of soft materials, such as nylon or polyester, to ensure patient comfort during use.
[0041] One end of the fall prevention assist belt 20 is fixed to the connecting block 19, and the other end is wrapped around the patient's waist or other parts that need to be fixed to provide additional support and stability. The external fixed connection of the axillary support bar 11 is an anti-slip sleeve 21, a safety feature used to prevent the patient from falling accidentally when using the support frame, so as to ensure that the patient remains stable during walking. The external fixed connection of the anti-slip sleeve 21 is a pole 22, a pole perpendicular to the ground. The design of the pole 22 should ensure that it has sufficient strength and stability to withstand the patient's weight and other external forces.
[0042] The upright post 22 is externally fixedly connected to a handrail 23, a pair of handrails 23 located on both sides of the upright post 22, to help the patient maintain balance and stability. The upright post 22 is also externally fixedly connected to a support rod 24, a horizontal rod used to support the casters 25. The support rod 24 is designed to ensure sufficient strength and stability to withstand the patient's weight and other external forces. The support rod 24 is externally fixedly connected to a caster 25, a set of wheels located at the bottom of the support frame, to help the patient move easily.
[0043] Working principle: When using this gait training support frame for post-operative rehabilitation in orthopedic surgery, the motor 3 is first started by controlling the button 2 on the rehabilitation gait housing 1. The rotation of the motor 3 drives the connecting rod 4, which is rotatably connected to it, to rotate. The rotation of the connecting rod 4 causes the follower rods 5, which are rotatably connected on the front and rear sides, to move accordingly. The movement of the follower rods 5 causes the fixed plate 6 to move. The sliding base 7, which is fixedly connected to the fixed plate 6, slides on the fixed rod 8. The fixed plate 9 outside the fixed rod 8 provides auxiliary support and other functions.
[0044] The position of the fixed plate 3 10 at the top of the sliding base 7 is also changed accordingly, and the positions of the axillary support rods 11 fixedly connected on the left and right sides of the fixed plate 3 10 are also adjusted. Through the linkage of such a series of components, the width of the rehabilitation gait training support frame is adjusted to adapt to the body shape needs of different patients and ensure the use of the patient during the rehabilitation gait training process.
[0045] When a patient uses this gait training support frame, if the patient sways or has a tendency to fall, the movement of their body will cause the axillary support bar 11 to move accordingly. The slide rail 12, which is fixedly connected to the outside of the axillary support bar 11, moves accordingly. The sliding block 15 in the slide groove 13 inside the slide rail 12 will slide within the slide groove 13. The sliding block 15 will be restricted by the limiting block 14 so that it moves within a suitable range. At the same time, the sliding block 15 drives the externally fixed slide rail 2 16 to move, and the extension spring 18 outside the slide rail 2 16 will be stretched or compressed.
[0046] The extension spring 18 is connected to the anti-fall aid belt 20 via the connecting block 19. One end of the anti-fall aid belt 20 is fixed to the connecting block 19, and the other end is wrapped around the patient's waist or other parts that need to be fixed. When the patient's body sways, the extension spring 18 absorbs part of the impact force, and the anti-fall aid belt 20 provides the patient with extra support and stability, thereby preventing the patient from falling and ensuring the patient's safety during the use of the support frame.
[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
