Abstract
Description
Technical Field
[0001] This invention belongs to the field of orthopedic nursing, and in particular relates to a walking aid device for orthopedic rehabilitation. Background Technology
[0002] Following orthopedic surgery, patients typically require early ambulation to promote rehabilitation and reduce postoperative complications (such as muscle atrophy, joint stiffness, and deep vein thrombosis). Walking aids, as common rehabilitation assistive devices, provide support and balance during walking, helping patients gradually regain motor function. Traditional walking aids primarily provide static support through hand gripping, and their stability relies on the user's upper limb strength. When walking, the user must repeatedly lift or push the walking aid, relying on continuous arm exertion to maintain balance. Prolonged use can easily cause fatigue in the upper limbs and shoulder / back muscles, and even lead to secondary injuries, thus delaying the rehabilitation process. Summary of the Invention
[0003] The purpose of this invention is to provide a walking aid for orthopedic rehabilitation, so as to solve the technical problems mentioned in the background art.
[0004] To achieve the above objectives, the specific technical solution of the orthopedic rehabilitation walking aid device of the present invention is as follows:
[0005] A walking aid for orthopedic rehabilitation includes two parallel base plates, a support frame positioned above the base plates and connected to the base plates by pillars, and a lifting frame positioned above the support frame and connected to the lifting frame by an adjusting assembly. Vertical supports for assisting the user's body are mounted on the lifting frame, symmetrically arranged about the longitudinal centerline of the lifting frame, with the top surfaces of the two supports able to support the user under the armpits. Universal wheels with brakes are distributed along the length of the bottom surfaces of the two base plates.
[0006] Furthermore, both the lifting frame and the support frame are C-shaped, and the open ends of both the lifting frame and the support frame face the same side. The bracket is located on the connecting plate of the lifting frame.
[0007] Furthermore, the adjustment assembly includes multiple screws rotatably mounted on the bottom surface of the lifting frame, with the screws threadedly connected to the support frame. Each screw is connected via a transmission unit, which includes a first synchronous pulley on each screw located on the bottom surface of the lifting frame. Two second synchronous pulleys are located on the two screws furthest from the opening of the lifting frame, both located below the first synchronous pulleys. The first synchronous pulleys on the same side are connected by a first synchronous belt, and the second synchronous pulleys are connected by a second synchronous belt. One of the screws on the top surface of the lifting frame, near its opening, penetrates the lifting frame, and a handwheel is located at the penetrating end of the screw, with an eccentrically positioned handle on the handwheel.
[0008] Furthermore, the bracket is U-shaped, and a sliding frame is slidably mounted on its vertical plate, with the two sliding frames connected by a handle. An adjusting bolt is threaded onto one of the sliding frames of the bracket, and the adjusting bolt passes through the sliding frame and contacts the vertical plate of the bracket.
[0009] Furthermore, the bottom end of the support frame is provided with a support arm, which is slidably connected to the connecting plate of the lifting frame, and a sliding hole is opened on the support arm for sliding with the connecting plate of the lifting frame. An adjustment device for adjusting the distance between the two support arms is provided on the lifting frame. The adjustment device includes fixing blocks at both ends of the connecting plate of the lifting frame, and a double-threaded rod is rotatably provided between the two fixing blocks. The threads at both ends of the double-threaded rod are threadedly connected to the connecting blocks. A crank handle is provided at one end of the double-threaded rod.
[0010] Furthermore, the lifting frame has guide rails at both ends of the connecting plate, and the tops of the two guide rails are connected by a support plate.
[0011] Furthermore, the guide rail is connected to its corresponding base plate by a reinforcing plate, and the reinforcing plate and its corresponding guide rail are slidably connected.
[0012] The orthopedic rehabilitation walking aid of the present invention has the following advantages:
[0013] This invention utilizes a support frame on a lifting device to assist the user's body. The user can place two supports under their armpits. During walking, the support eliminates the need for the user to rely entirely on arm strength for balance, significantly reducing the continuous exertion of upper limb muscles and preventing muscle soreness or injury after prolonged training, thus improving the sustainability of rehabilitation training. Simultaneously, when the user needs to rest, the support reduces stress on the legs, enhancing the user's overall experience with the device. Attached Figure Description

[0020] To better understand the purpose, structure, and function of this invention, a walking aid device for orthopedic rehabilitation will be described in further detail below with reference to the accompanying drawings.
[0021] like Figures 1 to 4 As shown, an orthopedic rehabilitation walking aid of the present invention includes two parallel base plates 1 and a support frame 8 disposed above the two base plates 1. The support frame 8 is connected to the two base plates 1 by a pillar 2, and the pillar 2 is vertically disposed between the support frame 8 and the base plates 1. A lifting frame 3 is disposed above the support frame 8, and the user can directly grip the lifting frame 3 to achieve the body support effect of the device. At the same time, a bracket 5 is also vertically disposed on the lifting frame 3 to provide auxiliary support for the user's body, and the brackets 5 are symmetrically arranged about the longitudinal center line of the lifting frame 3. The top surfaces of the two brackets 5 can support the user under the armpits. Through the support of the body by the underarm brackets 5 and the dual support structure of the body by the hand gripping the lifting frame 3, the user does not need to rely entirely on arm strength to maintain balance, greatly reducing the continuous exertion of upper limb muscles, preventing muscle soreness or injury after long-term training, and improving the sustainability of rehabilitation training.
[0022] The support frame 8 and the lifting frame 3 are connected by an adjustment component. The height of the lifting frame 3 and the support 5 can be adjusted according to the user's height to achieve a personalized fit. Furthermore, depending on the user's recovery progress, underarm support can be the primary method during the initial rehabilitation training after surgery, gradually transitioning to hand support later, thus promoting a gradual recovery process.
[0023] Specifically, when using this device, the user can stand between the two base plates 1, place their armpits on the top surface of the symmetrically arranged supports 5, and use the adjustment components to raise the supports 5 to a suitable position. Then, the user holds the hand support components with both hands. At this time, the body weight is distributed through the armpit supports 5 and the hand support components, thereby reducing the support force on the arms and improving the user experience.
[0024] To facilitate the movement of the device by the user, casters 21 with brakes are distributed along the length of the bottom surfaces of the two base plates 1. The casters 21 can rotate flexibly in multiple directions to adapt to turning or gait adjustment. Furthermore, as a prior art form, the casters 21 with brakes can be locked when the device is stationary by pressing or manually operating the brakes, preventing the device from accidentally slipping.
[0025] Specifically, both the lifting frame 3 and the support frame 8 are C-shaped, and the opening ends of both the lifting frame 3 and the support frame 8 face the same side. The bracket 5, used for underarm support, is specifically set on the connecting plate of the lifting frame 3. The design of the opening ends of the lifting frame 3 and the support frame 8 facing the same side forms a semi-enclosed structure, allowing the user to easily enter the interior of the device from the opening side without having to move their body significantly, thus improving the user's convenience in using the device.
[0026] like Figure 1 and Figure 2 As shown, the adjustment assembly for adjusting the height of the lifting frame 3 includes multiple screws 9 rotatably mounted on the bottom surface of the lifting frame 3. Four screws 9 are located on the bottom surface of the lifting frame 3, and the screws 9 are threadedly connected to the support frame 8. To ensure that all screws 9 rotate at the same speed and in the same direction, keeping the lifting frame 3 horizontal during height adjustment, each screw 9 is connected by a transmission unit. The transmission unit includes a synchronous pulley 10 mounted on each screw 9 on the bottom surface of the lifting frame 3. Simultaneously, synchronous pulleys 12 are mounted on two screws 9 located away from the opening of the lifting frame 3, and both synchronous pulleys 12 are located below synchronous pulleys 10. Synchronous pulleys 10 on the same side of the bottom surface of the lifting frame 3 are connected by a synchronous belt 11, while synchronous pulleys 12 are connected by a synchronous belt 13. Rotating any screw 9 will cause the remaining screws 9 to rotate in the same direction and at the same speed under the action of the transmission unit. This prevents the lifting frame 3 from tilting to one side and prevents instability or jamming of the lifting frame 3. It should be noted that the timing pulley 10 and timing pulley 2 12 in the transmission unit are connected by timing belt 11 and timing belt 2 13 respectively, which can prevent the timing pulley 10 and timing pulley 2 12 from slipping with the timing belt 11 and timing belt 2 13 connected to them, and further improve the stability of the lifting frame 3 during lifting.
[0027] To facilitate the rotation of the screws 9, one of the screws 9, near the opening side of the top surface of the lifting frame 3, passes through the lifting frame 3. A handwheel 14 is provided on the through end of the screw 9, coaxially arranged with the screw 9. A handle 15 is eccentrically mounted on the handwheel 14, vertically positioned. The handwheel 14's proximity to the opening end of the lifting frame 3 provides the user with ample operating space. Alternatively, one handwheel 14 can be provided on each of the two screws 9 near the opening end of the lifting frame 3, allowing the user to operate the handwheel 14 from different directions.
[0028] Specifically, the user rotates the handle 15 on the handwheel 14, causing the drive screw 9, which runs through the lifting frame 3, to rotate. The drive screw 9 drives the driven screw 9 on the same side to rotate synchronously via the first synchronous pulley 10 and the first synchronous belt 11. The second synchronous pulley 12 on this driven screw 9 also rotates, and the second synchronous pulley 12 and the second synchronous belt 13 further link the screw 9 away from the opening side to rotate. The first synchronous pulley 10 of this screw 9 also rotates, driving the connected first synchronous pulley 10 to rotate via the first synchronous belt 11, ultimately achieving the same speed and direction of rotation for all screws 9. The threaded connection between the screw 9 and the support frame 8 converts the rotational motion into the vertical displacement of the lifting frame 3, achieving smooth lifting. The threaded connection between the screw 9 and the support frame 8 prevents the lifting frame 3 from rotating on its own without external force, ensuring reliable locking of the height of the support 5.
[0029] This device can be used in different ways depending on the user's postoperative stage. Specifically, in the early postoperative period, the height of the lifting frame 3 is increased so that the axillary support 5 bears the main weight, reducing the load on the lower limbs. In the mid-rehabilitation period, the height of the support 5 is gradually reduced, transitioning to hand support as the primary method, to strengthen the user's ability to walk independently.
[0030] like Figure 1 and Figure 3 As shown, the bracket 5 is U-shaped, with sliding frames 19 slidably mounted on its two vertical plates, and the two sliding frames 19 are connected by a handle 6. An adjusting bolt 20 is threaded onto one of the sliding frames 19 of the bracket 5, and the adjusting screw 9 passes through the sliding frame 19 and contacts the vertical plate of the bracket 5. The adjusting bolt 20 provides a mechanical lock for the sliding frame 19, and the threaded tightening structure ensures that the position of the sliding frame 19 is fixed. After the sliding frame 19 is fixed, the handle 6 mounted on the sliding frame 19 is also fixed. In addition to holding the lifting frame 3, the user can also hold the handle 6, and the position of the sliding frame 19 and the handle 6 can be adjusted by adjusting the adjusting screw 9 to adapt to different uses.
[0031] The bottom end of the support 5 is provided with a support arm 4, which is slidably connected to the connecting plate of the lifting frame 3. A sliding hole 7 is provided on the support arm 4 for sliding with the connecting plate of the lifting frame 3. An adjustment device for adjusting the distance between the two support arms 4 is provided on the lifting frame 3. Specifically, the adjustment device includes fixed blocks 18 at both ends of the connecting plate of the lifting frame 3, and a bidirectional threaded rod 17 is rotatably provided between the two fixed blocks 18. The threads at both ends of the bidirectional threaded rod 17 are threadedly connected to connecting blocks 16 respectively. A crank is provided at one end of the bidirectional threaded rod 17. The bidirectional threaded rod 17 transmission mechanism achieves symmetrical synchronous adjustment of the two support arms 4, and the threaded connection between the bidirectional threaded rod 17 and the connecting blocks 16 has a self-locking characteristic to ensure that the position of the connecting blocks 16 is completely fixed after adjustment, with no risk of loosening. Rotating the crank drives the bidirectional threaded rod 17 to rotate. The opposing threads at both ends of the threaded rod drive the two connecting blocks 16 to move towards / away from each other. The connecting blocks 16 drive the support arms 4 to slide synchronously along the sliding hole 7, thereby achieving precise adjustment of the distance between the two supports 5. The spacing between the two supports 5 can be adjusted to accommodate users of different body sizes.
[0032] Preferably, the lifting frame 3 has guide rails 22 at both ends of the connecting plate, and the tops of the two guide rails 22 are connected by a support plate 23. During exercise, the user can also place their arms on the support plate 23 for support, thereby enhancing the user's experience with the device. Figure 1 and Figure 4 As shown, the guide rail 22 is connected to its corresponding base plate 1 via a reinforcing plate 24, and the reinforcing plate 24 is slidably mounted to the guide rail 22. The reinforcing plate 24 is inclined between the guide rail 22 and the base plate 1, which improves the stability of the device and prevents it from tipping over. Furthermore, the reinforcing plate 24 facilitates the movement of the device.
[0033] Instructions for use: The user enters the device through the opening of the lifting frame 3. The user or another person then turns the handwheel 14. The handwheel 14, through the transmission unit, drives the screws 9 synchronously at the same speed, adjusting the lifting frame 3 to an appropriate height and the support 5 to provide underarm support. Then, disconnect the adjusting bolt 20 from the support 5, adjust the grip 6 to the appropriate position, and tighten the adjusting bolt 20. The crank handle can then be turned, causing the double-threaded rod 17 to rotate. This causes the connecting block 16 on the double-threaded rod 17 to move, along with the support arm 4 on the connecting block 16, ultimately adjusting the spacing of the support 5 on the support arm 4. Once the support 5 is adjusted to the appropriate position, the device can be used for assisted walking training.
