Description
Technical Field
[0001] This utility model relates to the field of orthopedic rehabilitation technology, and in particular to a postoperative gait training device. Background Technology
[0002] In the fields of orthopedic rehabilitation (such as hip replacement, knee replacement, and post-fracture surgery) and sports rehabilitation, postoperative gait training devices are a type of rehabilitation equipment specifically designed to improve patients' walking function, standardize stride length, and reconstruct normal gait patterns. Its core objective is to help patients gradually regain normal walking ability during the postoperative recovery period through scientific structural design and training logic, avoid secondary injuries caused by excessively large or small strides or gait asymmetry, and improve walking stability and coordination.
[0003] Postoperative gait training devices mostly achieve gait adjustment through mechanical limiting or electronic guidance. However, during training, the pedals of mechanical limiting devices are mostly smooth and hard surfaces. When patients take steps, they can only perceive the gait boundary through tactile obstruction. The plantar pressure distribution cannot obtain dynamic feedback, and it cannot simulate the complex tactile feedback when the sole of the foot contacts the ground during normal walking. Plantar proprioception is an important sensory input for the human body to maintain balance and adjust gait. The lack of such stimulation will make it difficult for patients to adjust their gait independently according to the ground environment after removing the device. The training effect is disconnected from the actual walking scenario, affecting the stability and practicality of gait reconstruction, and ultimately leading to poor overall rehabilitation results. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a postoperative gait training device, which aims to improve the problem of poor training effect caused by the lack of effective stimulation of proprioception of the sole in the prior art.

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0018] Reference Figure 1 and Figure 4 An embodiment of this utility model is provided: a postoperative gait training device, including a fixed plate 1, with support plates 2 fixedly connected to the left and right ends of the front side of the fixed plate 1, and adjustment mechanisms 3 provided on the opposite sides of the two support plates 2. The adjustment mechanisms 3 are used to adjust the gait, and a stimulation mechanism 4 is provided at the bottom of the adjustment mechanism 3. The stimulation mechanism 4 is used to effectively stimulate the sole of the foot, and a moving mechanism 5 is provided at the top of the fixed plate 1. The stimulation mechanism 4 includes two foot pedals 41, with the opposite sides of the two foot pedals 41 respectively positioned between adjacent parts of the adjustment mechanism 3. A stride guide pad 42 is bonded to the bottom inner side of each foot pedal 41, and multiple massage particles 43 are fixedly connected to the top of each stride guide pad 42. A thick silicone film 44 is installed on the top of each of the multiple massage particles 43, and a thin silicone film 45 is installed on the top of each of the two thick silicone films 44. An installation component 46 is provided on the opposite side of each foot pedal 41, and a fixing component 47 is provided on the top of each foot pedal 41. Specifically, the stride guidance pad 42 is made of environmentally friendly foam, 1cm thick, and measures 200cm long x 80cm wide, with rounded edges. It features left and right footprints; the left footprint is blue, and the right footprint is red. The spacing between the left and right footprints is set according to the standard stride length and can be adjusted using replaceable stickers. Both the left and right footprint areas are equipped with massage particles 43, distributed according to the foot reflex zones. The heel area features circular particles with a diameter of 5mm and a height of 3mm. The foot features elliptical particles arranged in a dense pattern. The forefoot area has elliptical particles with a diameter of 3mm and a height of 2mm, arranged along the metatarsal direction. The inner arch area has sparsely distributed small particles with a diameter of 2mm. The surface of the massage particles 43 is covered with a removable thin silicone film 45 and a thick silicone film 44. The front and rear ends of the left and right foot prints are equipped with Velcro straps 471. The stride guide pad 42 has scale lines every 10cm along its length. The left and right foot prints are accompanied by text indicating weight transfer. An arrow is drawn at the front end of the foot print. Before using the device, the foot pedal 41 is connected and fixed to the adjustment mechanism 3 by the installation component 46. Depending on the patient's recovery stage, it is possible to install a thin silicone membrane 45 and a thick silicone membrane 44. In the early postoperative period, the thin silicone membrane 45 is covered on the surface of the massage particles 43. The patient can choose whether to use the fixation component 47 at the left and right footprints to fix the foot according to their own situation. Selective fixation of the foot is achieved by the cooperation of the Velcro strap 471 and the foot pedal 41. During training, the patient steps on the left and right footprints of the gait guide pad 42 and walks according to the arrows at the front of the footprints and the side weight transfer prompts. The scale lines on the gait guide pad 42 are used to record the daily gait. When the sole of the foot comes into contact with the massage particles 43, the particles in different reflex zones stimulate the sole of the foot according to the preset shape and distribution. The thin silicone film 45 buffers the direct pressure of the massage particles 43 on the sole of the foot. Through the cooperation of the gait guide pad 42 and the massage particles 43, gait guidance and initial stimulation of the sole of the foot are achieved. As rehabilitation progresses, the thin silicone membrane 45 is removed. If further stimulation is needed, the thick silicone membrane 44 can be removed, allowing the sole of the foot to directly contact the massage particles 43. The dense round particles in the heel area, the oval particles arranged along the metatarsal bones in the forefoot area, and the sparse small particles on the inner side of the arch provide targeted stimulation to different areas of the sole. Through the combination of the massage particles 43 with the thin silicone membrane 45 and the thick silicone membrane 44, the intensity of stimulation can be adjusted in stages. When the stride standard needs to be adjusted, replace the replaceable sticker on the stride guide pad 42 to change the distance between the left and right foot prints, adapting to the stride training needs of the patient in the rehabilitation process. Through the combination of the replaceable sticker and the stride guide pad 42, the stride standard can be flexibly adjusted. During maintenance, the foot pedal 41 can be removed from the adjustment mechanism 3 by installing component 46, the stride guide pad 42 can be removed separately for cleaning, and the thin silicone film 45 and thick silicone film 44 on the surface of the massage particles 43 can be directly removed and replaced. The detachable design of the installation component 46 and the silicone film improves the ease of maintenance of the stimulation mechanism 4, meets the needs of stride training and foot stimulation at different rehabilitation stages after surgery, and ensures the targetedness and safety of the training.
[0019] Reference Figure 1 , Figure 2 and Figure 3 The adjustment mechanism 3 includes two rotating rods 31. The outer walls of the two rotating rods 31 are rotatably connected to the inside of the two support plates 2. Rotating gears 32 are fixedly connected to the opposite sides of the two rotating rods 31. Fixed covers 33 are installed on the opposite sides of the two support plates 2. Telescopic rods 34 are fixedly connected to the rear inside of the two fixed covers 33. Racks 35 are fixedly connected to the front of the two telescopic rods 34. The bottom of the two racks 35 meshes with the outer walls of the two rotating gears 32. Support components 36 are provided on the opposite sides of the two racks 35. Specifically, before using the device, the adjustment mechanism 3 is adjusted according to the patient's initial postoperative stride requirements. The fixed cover 33 is fixed on the side away from the support plate 2, providing an installation base for the telescopic rod 34 and the rack 35. The telescopic rod 34 is activated, and the extension or retraction of the telescopic rod 34 drives the rack 35 to move back and forth along the inside of the fixed cover 33. The bottom of the rack 35 meshes with the outer wall of the rotating gear 32. The movement of the rack 35 drives the rotating gear 32 to rotate. Through the cooperation of the telescopic rod 34 and the rack 35, the rotation drive of the rotating gear 32 is realized. When the rotating gear 32 rotates, it drives the rotating rod 31 fixed to it to rotate synchronously along the inside of the support plate 2. The rotation of the rotating rod 31 changes its connection angle with the stimulation mechanism 4, thereby adjusting the distance between the two foot pedals 41. The support assembly 36 moves with the rack 35 and adjusts its position synchronously, providing lateral support for the rack 35, preventing the rack 35 from tilting during movement, and ensuring that the rack 35 and the rotating gear 32 always remain in mesh. Through the cooperation of the rotating rod 31 and the rotating gear 32, the stride distance can be adjusted. As the patient's rehabilitation progresses, when it is necessary to increase or decrease the stride length, the adjustment process is repeated. The telescopic rod 34 extends or retracts in the opposite direction, causing the rack 35 to move in the opposite direction. The rotating gear 32 and the rotating rod 31 rotate in the opposite direction, and the distance between the two foot pedals 41 changes accordingly. The support component 36 continuously provides support for the rack 35, ensuring structural stability during the adjustment process. Through the bidirectional adjustment of the telescopic rod 34, the stride length distance can be flexibly adjusted. After adjustment, the telescopic rod 34 stops operating and maintains its current length, the rack 35 is fixed in position, the rotating gear 32 and the rotating rod 31 no longer rotate, the distance between the two foot pedals 41 is maintained in the adjusted state, the support component 36 maintains support for the rack 35 to prevent the rack 35 from shifting due to force during patient training, and ensures the stability of the stride distance. Through the locking function of the telescopic rod 34 and the cooperation of the support component 36, the stability of the stride after adjustment is achieved. When maintaining the adjustment mechanism 3, the removable fixing cover 33 can be used to check the operating status of the internal telescopic rod 34 and rack 35. The structural design of the support component 36 makes it easy to remove it for cleaning or replacement. The rotating connection structure between the rotating rod 31 and the support plate 2 allows for the addition of lubricant to ensure smooth rotation. The removable design of the fixing cover 33 improves the ease of maintenance of the adjustment mechanism 3, realizes precise adjustment and stable maintenance of stride distance, adapts to the training needs of patients at different rehabilitation stages, provides reliable structural support for postoperative stride training, and improves the applicability and stability of the training device.
[0020] Reference Figure 3 and Figure 4 The mounting component 46 includes multiple connecting blocks 461, which are fixedly connected to each other on opposite sides of two foot pedals 41. Each connecting block 461 has a slidably connected fixing block 462 on its outer wall. Each fixing block 462 has two bolts 463 threadedly connected to its bottom. The fixing component 47 includes multiple Velcro straps 471, whose bottoms are fixedly connected to the front and rear top sides of the two foot pedals 41. Each Velcro strap 471 has a D-ring 472 fixedly connected to its top. The support component 36 includes two sliding plates 361, which are fixedly connected to each other on opposite sides of two racks 35. Each fixing cover 33 has a groove 362 on opposite sides of its interior. Each sliding plate 361 has a bead 363 fixedly connected to opposite sides of its interior. The outer walls of the two beads 363 are slidably connected to the interiors of the two grooves 362. Specifically, when installing the foot pedal 41, the connecting block 461 is slid along the inner wall of the fixing block 462, so that the foot pedal 41 is positioned at the bottom of the adjustment mechanism 3 along with the connecting block 461. The bolt 463 is rotated through the fixing block 462 and screwed into the corresponding threaded hole of the connecting block 461. Through the cooperation of the bolt 463 and the fixing block 462, the connecting block 461 and the fixing block 462 are fixed, thereby completing the connection and installation of the foot pedal 41 and the adjustment mechanism 3. When using the fixation component 47, the patient can choose whether to fix the foot according to their own needs. If fixation is required, the foot is placed on the stride guide pad 42 at the top of the foot pedal 41, and the Velcro strap 471 is pulled around the foot. The tightness of the strap is adjusted by the D-ring 472 so that the Velcro strap 471 fits the foot and is fixed in place. If fixation is not required, the Velcro strap 471 is loosened so that it is located on both sides of the top of the foot pedal 41 without affecting foot movement. The foot fixation state can be flexibly switched through the cooperation of the Velcro strap 471 and the D-ring 472. When the adjusting mechanism 3 is in operation, the rack 35 moves back and forth along the inside of the fixed cover 33, which drives the sliding plate 361 to move synchronously. The ball 363 on the side away from the sliding plate 361 slides along the inner wall of the groove 362. The ball 363 reduces the frictional resistance between the sliding plate 361 and the groove 362. The groove 362 restricts the movement direction of the ball 363, ensuring that the sliding plate 361 moves smoothly with the rack 35. Through the cooperation of the sliding plate 361 and the ball 363, lateral support is provided for the rack 35. During stride adjustment, the ball bearing 363 of the support component 36 always slides along the slide groove 362 to prevent the rack 35 from tilting due to force, ensuring the stable meshing state between the rack 35 and the rotating gear 32. The bolt 463 of the mounting component 46 keeps the connecting block 461 and the fixing block 462 fixed, preventing the foot pedal 41 from shifting during patient training. Through the cooperation of the support component 36 and the mounting component 46, the overall structural stability of the device is maintained. During maintenance, the connecting block 461 and the fixing block 462 can be separated by unscrewing bolt 463. The foot pedal 41 can be removed for cleaning or replacement. The Velcro strap 471 can be removed from the top of the foot pedal 41 for easy cleaning or replacement. The fixing structure of the sliding plate 361 and the rack 35 allows for separate inspection of the wear of the rotating ball 363. If necessary, the rotating ball 363 can be replaced. The detachable design of the mounting component 46 and the fixing component 47 improves the ease of maintenance of the device. It enables quick installation of the foot pedal 41, flexible adaptation of foot fixation, and stable support of the adjustment mechanism 3, providing a reliable structural guarantee for postoperative stride training and improving the applicability and stability of the device.
[0021] Reference Figure 5The moving mechanism 5 includes a motor 51, the bottom of which is fixedly connected to the top left side of the fixed plate 1. A protective cover 52 is fixedly connected to the top of the fixed plate 1. A connecting rod 53 is rotatably connected inside the protective cover 52. The output end of the motor 51 is fixedly connected to the left side of the protective cover 52. Bevel gears 54 are fixedly connected to both the left and right sides of the outer wall of the protective cover 52. Bevel gears 55 are meshed at the bottom of both bevel gears 54. Threaded rods 56 are fixedly connected to the bottom of both bevel gears 55. The same moving plate 57 is threadedly connected to the outer wall of both threaded rods 56. Limiting components 58 are provided on both the left and right sides of the fixed plate 1. A blocking component 59 is provided on the top front side of the movable plate 57. The limiting component 58 includes multiple limiting blocks 581. The multiple limiting blocks 581 are fixedly connected to the left and right sides inside the movable plate 57. Limiting grooves 582 are opened on both the left and right sides inside the fixed plate 1. The outer walls of the multiple limiting blocks 581 are slidably connected to the inside of the multiple limiting grooves 582. The blocking component 59 includes a rotating seat 591. The bottom of the rotating seat 591 is fixedly connected to the top front side of the movable plate 57. A guardrail 592 is rotatably connected inside the rotating seat 591. Specifically, before training, the patient adjusts the position of the moving plate 57 according to the training needs, starts the motor 51, and the output end of the motor 51 drives the protective cover 52 to rotate. The protective cover 52 drives the internal connecting rod 53 and the bevel gear 54 on the outer wall to rotate synchronously. The bevel gear 54 meshes with the bevel gear 55, transmitting the rotational power to the bevel gear 55, causing the bevel gear 55 to drive the threaded rod 56 at the bottom to rotate. Through the cooperation of the motor 51 and the bevel gear 54, the output and transmission of rotational power are realized. When the threaded rod 56 rotates, its outer wall engages with the threaded structure of the movable plate 57, pushing the movable plate 57 to rise and fall in the vertical direction. During the movement of the movable plate 57, the limiting blocks 581 on the left and right sides slide along the inner wall of the limiting groove 582 of the fixed plate 1. The limiting groove 582 restricts the movement direction of the limiting blocks 581, preventing the movable plate 57 from tilting when rising and falling. Through the cooperation between the threaded rod 56 and the movable plate 57, the rotational motion is converted into linear motion, and the position adjustment of the movable plate 57 is completed. When the moving plate 57 needs to be raised, the motor 51 rotates in the forward direction, driving the first bevel gear 54, the second bevel gear 55 and the threaded rod 56 to rotate in the forward direction. The moving plate 57 moves upward with the rotation of the threaded rod 56. When the moving plate 57 needs to be lowered, the motor 51 rotates in the reverse direction, and the components operate in the opposite direction. The moving plate 57 descends synchronously. During the adjustment process, the limit block 581 always slides along the limit groove 582 to ensure that the moving plate 57 rises and falls smoothly. The movement stability of the moving plate 57 is guaranteed by the cooperation between the limit block 581 and the limit groove 582. During patient training, the guardrail 592 inside the rotating seat 591 is rotated to a vertical position, providing support and preventing the patient from falling forward. The moving plate 57 is kept at the adjusted height, the motor 51 stops running, and the threaded rod 56 engages with the moving plate 57 to achieve self-locking, maintaining the stability of the moving plate 57. Through the cooperation of the rotating seat 591 and the guardrail 592, safety protection is achieved during training. After training, rotate the guardrail 592 in the opposite direction to make it fit the top of the moving plate 57 to reduce space occupation. Start the motor 51 to drive the moving plate 57 down to the initial position. The limit block 581 slides back to its original position along the limit groove 582 with the moving plate 57. The rotatable design of the guardrail 592 improves the convenience of device storage. During maintenance, the removable protective cover 52 can be used to check the meshing status of the internal connecting rod 53, bevel gear 1 54 and bevel gear 2 55. Impurities can be cleaned from the inner wall of the limiting groove 582 to ensure smooth sliding of the limiting block 581. The motor 51 can be disassembled and repaired separately through the bottom fixing structure. The removable design of the protective cover 52 improves the ease of maintenance of the moving mechanism 5, realizes the precise lifting and lowering of the moving plate 57 and training safety protection, provides reliable moving support for postoperative stride training, and improves the safety and applicability of the device.
[0022] Working principle: Before using the device, complete the basic installation and parameter adjustment. Install the foot pedal 41 through the installation component 46. Slide the connecting block 461 along the inner wall of the fixing block 462 to position the foot pedal 41 at the preset position at the bottom of the adjustment mechanism 3. Rotate the bolt 463 through the fixing block 462 and screw it into the corresponding threaded hole of the connecting block 461 to complete the connection between the foot pedal 41 and the adjustment mechanism 3. The stride guide pad 42 is made of environmentally friendly foam pad with a thickness of 1cm and a size of 200cm long × 80cm wide. The edges are rounded and there are blue left footprints and red right footprints on it, with spacing between them. Set according to the standard stride length and adjustable with replaceable stickers, with scale lines every 10cm along the length direction, weight transfer prompts next to the footprint, and an arrow at the front. Massage particles 43 are set in the footprint area, distributed according to the reflex zones of the sole of the foot. The heel area has densely arranged circular particles with a diameter of 5mm and a height of 3mm, the forefoot area has oval particles with a diameter of 3mm and a height of 2mm arranged along the metatarsal direction, and the inner arch area has sparsely distributed small particles with a diameter of 2mm. The surface is covered with a removable thin silicone film 45 and a thick silicone film 44. Velcro straps 471 are set at the front and back ends of the footprint. Adjustment mechanism 3 is adjusted according to the patient's initial postoperative stride requirements. Fixing cover 33 is fixed to the side away from support plate 2. Telescopic rod 34 is activated. Telescopic rod 34 extends or retracts, causing rack 35 to move back and forth along the inside of fixing cover 33. The bottom of rack 35 meshes with the outer wall of rotating gear 32, causing rotating gear 32 to rotate. This causes rotating rod 31, which is fixed to it, to rotate synchronously along the inside of support plate 2, changing the connection angle between rotating rod 31 and stimulation mechanism 4, and adjusting the distance between the two foot pedals 41. Sliding plate 361 of support component 36 moves with rack 35, and rotating ball 363 slides along slide groove 362 to provide lateral support for rack 35, ensuring that rack 35 and rotating gear 32 are always meshed. After adjustment, telescopic rod 34 stops operating and maintains its current length, keeping the distance between foot pedals 41 stable. Simultaneously, the moving mechanism 5 is adjusted according to training needs, and the motor 51 is started. The output end of the motor 51 drives the protective cover 52 to rotate. The protective cover 52 drives the connecting rod 53 and the first bevel gear 54 to rotate synchronously. The first bevel gear 54 meshes with the second bevel gear 55, driving the threaded rod 56 to rotate. The threaded rod 56 and the moving plate 57 are threadedly engaged to push the moving plate 57 to rise and fall in the vertical direction. When the moving plate 57 moves, the limiting block 581 slides along the limiting groove 582 to prevent the moving plate 57 from tilting. When the moving plate 57 needs to be raised, the motor 51 rotates in the forward direction. When it needs to be lowered, it rotates in the reverse direction. After adjusting to the height suitable for the patient, the motor 51 stops running. The threaded rod 56 and the moving plate 57 are threadedly self-locked to maintain a stable position. Once the device is ready, the patient begins training. Depending on the rehabilitation stage, the patient chooses whether to install a thin silicone membrane 45 or a thick silicone membrane 44. In the early postoperative period, the thin silicone membrane 45 is placed over the surface of the massage particles 43. The patient chooses whether to use the fixation component 47 based on their own condition. If fixation is required, the foot is placed on the footprint of the gait guide pad 42, and the Velcro strap 471 is pulled around the foot. The tightness is adjusted and the fastener is secured using the D-ring buckle 472. If fixation is not required, the Velcro strap 471 is loosened and placed on both sides of the top of the foot pedal 41. The patient steps on the footprint and walks according to the arrow at the front of the footprint and the text indicating the center of gravity shift on the side. The scale lines of the gait guide pad 42 record the daily step length. When the sole of the foot contacts the massage particles 43, the particles in different reflex zones stimulate the foot, and the thin silicone membrane 45 buffers the direct pressure. As rehabilitation progresses, the thin silicone membrane 45 is removed. If enhanced stimulation is needed, the thick silicone membrane 44 can be removed, allowing the soles of the feet to directly contact the massage particles 43. Particles in different areas provide targeted stimulation to the soles of the feet. When it is necessary to adjust the stride standard, replace the replaceable sticker on the stride guide pad 42 to change the spacing between footprints. During training, rotate the guardrail 592 inside the rotating seat 591 to a vertical position to provide blocking support for the patient and prevent tipping. After training, the guardrail 592 is rotated in the opposite direction to fit against the top of the moving plate 57. The motor 51 is started to drive the moving plate 57 down to the initial position. The limiting block 581 slides back to its original position along the limiting groove 582 with the moving plate 57. During maintenance, the foot pedal 41 can be removed by the bolts 463 of the mounting component 46. The stride guide pad 42 can be removed separately for cleaning. The thin silicone film 45, the thick silicone film 44, and the Velcro strap 471 can be removed and replaced. The adjustable mechanism 3 can be removed and fixed cover 33 to check the internal components and add lubricant to ensure smooth rotation. The moving mechanism 5 can be removed and protective cover 52 to check the internal engagement status and clean impurities from the limiting groove 582. The motor 51 can be disassembled and repaired separately. This achieves precise stride adjustment, graded adjustment of foot stimulation intensity, safety protection for patient training, and convenient maintenance of the device, meeting the training needs of different rehabilitation stages after surgery and ensuring the relevance and safety of the training.
