Description

Technical Field

[0001] This application relates to the field of medical rehabilitation equipment, specifically to a foot deformity correction device. Background Technology

[0002] Foot deformities are common orthopedic conditions in clinical practice, including various types such as high arches, inversion, and eversion. These deformities not only affect patients' walking function but can also lead to pain, abnormal posture, and a decline in quality of life. Currently, treatment methods for foot deformities mainly include surgical treatment and postoperative rehabilitation training. Among these, postoperative rehabilitation training is of great significance for restoring foot function and preventing recurrence of deformities.

[0003] In the field of foot deformity correction, various orthopedic devices have been developed and applied. However, existing foot deformity correction devices still have some shortcomings. First, there is a lack of systematic design and standardization in assistive devices for postoperative rehabilitation training of high arches, especially in terms of dedicated devices for promoting forefoot abduction and eversion to improve hindfoot inversion. Current rehabilitation training mostly relies on manual passive traction, braces, or manual assistance from physical therapists, which is not only inefficient but also makes it difficult for patients to achieve autonomous rehabilitation training. Second, functional rehabilitation devices based on the principle of the wooden block experiment are currently lacking in technology. There is a lack of dedicated devices on the market that can systematically simulate the wooden block experiment movements and support adjustable training intensity and angle. Most existing devices have fixed structures, making it difficult to flexibly adjust training parameters according to the patient's rehabilitation progress and meet personalized rehabilitation needs. Third, traditional physical therapy methods rely heavily on medical staff, with low patient participation, making it difficult to form a continuous home rehabilitation mechanism. This not only increases the burden on medical resources but also prolongs the patient's rehabilitation period.

[0004] Therefore, there is an urgent need to develop a device that can effectively correct foot deformities (especially high arches). This device should have adjustable training intensity and angle, support patients' self-training, and be able to simulate professional rehabilitation training movements, thereby improving rehabilitation efficiency and shortening the rehabilitation cycle. Summary of the Invention

[0005] This application addresses the problem that rehabilitation training for patients with high arches after surgery often relies on manual passive traction, braces, or manual assistance from physical therapists, resulting in low patient participation and difficulty in establishing a sustainable home rehabilitation mechanism. It provides a device suitable for postoperative rehabilitation and daily exercise and intervention for patients with mild high arches, reducing dependence on medical staff, increasing patient participation, and facilitating the formation of a sustainable foot deformity correction device.

[0011] The support rod is located at the bottom of the transverse central axis of the base;

[0012] The crossbar assembly includes two sets of crossbars, each set consisting of at least two parallel crossbars, and each crossbar has its two ends connected to the support base and the support rod respectively; the two sets of crossbars are mirror-symmetrically distributed along the axial direction of the support rod; each pedal corresponds to a set of crossbars, and the pedal is disposed on the upper surface of the corresponding crossbar.

[0021] The connecting assembly includes two sets of connecting elements, each set of connecting elements corresponding to one of the pedals. Each set of connecting elements includes at least one connecting element, and both ends of the connecting element are respectively connected to the support rod and the inner side of the pedal corresponding to the connecting element.

[0022] Optionally, one end of the connecting element is connected to the base of the pedal on the side near the support rod.

[0023] Optionally, the connecting element may be a spring element or a hydraulic cylinder.

The pedal assembly is slidably mounted on the load-bearing surface of the base and includes two pedals. The upper surfaces of the two pedals are inverted V-shaped and respectively mounted on both sides of the load-bearing surface of the base. The inverted V-shaped pedal structure effectively solves the problem of insufficient forefoot abduction and eversion during the rehabilitation process after high arch surgery, which leads to recurrence of hindfoot inversion or unstable correction effects. The inner-lower, outer-higher structure of the pedals can induce abduction and eversion movements in the patient's forefoot, simulating the rehabilitation principle of the block experiment. The slidable pedal assembly allows the distance between the pedals to be adjusted according to the user's own situation, reducing dependence on medical staff, increasing patient participation, and helping to form a continuous home rehabilitation mechanism. The foot deformity correction device has a simple and portable structure and is applicable to various scenarios. Attached Figure Description

[0042] The foot deformity correction device of this application is simple in structure and portable, applicable to various scenarios such as home rehabilitation equipment and hospital rehabilitation equipment. The foot deformity correction device, through its inverted V-shaped pedal structure, effectively solves the problem of insufficient forefoot abduction and eversion during high arch surgery rehabilitation, leading to recurrence of hindfoot inversion or unstable correction effects. The pedal's inner-low and outer-high structure induces abduction and eversion movements in the patient's forefoot, simulating the rehabilitation principle of the block experiment. The sliding pedal assembly allows for adjustment of the distance between the pedals based on the user's individual needs, reducing reliance on medical personnel, increasing patient participation, and contributing to a sustainable home rehabilitation mechanism.

[0043] Example 1

[0044] This application addresses the shortcomings of existing assistive devices for postoperative rehabilitation of high arches, which largely rely on passive traction, braces, or manual assistance from physical therapists, resulting in low patient participation and difficulty in establishing a sustainable home rehabilitation mechanism. (See also...) Figures 1-4 The foot deformity correction device provided in this embodiment includes a base 1 and a pedal assembly 2; the pedal assembly 2 is slidably disposed on the load-bearing surface of the base 1, and the pedal assembly 2 includes two pedals, the upper surfaces of the two pedals being inverted V-shaped and respectively disposed on both sides of the load-bearing surface of the base 1.

[0045] The foot deformity correction device of this application includes a base 1 and a pedal assembly 2. The pedal assembly 2 is slidably mounted on the load-bearing surface of the base 1. The pedal assembly 2 includes two pedals, the upper surfaces of which are inverted V-shaped and respectively mounted on both sides of the load-bearing surface of the base 1. The inverted V-shaped pedal structure effectively solves the problem of insufficient forefoot abduction and eversion during postoperative rehabilitation of high arches, leading to recurrence of hindfoot inversion or unstable corrective effects. The inner-lower, outer-higher structure of the pedals can induce abduction and eversion movements in the patient's forefoot, simulating the rehabilitation principle of the block experiment. The slidable pedal assembly 2 allows the distance between the pedals to be adjusted according to the user's own situation, reducing dependence on medical staff, increasing patient participation, and helping to form a continuous home rehabilitation mechanism. The foot deformity correction device is simple in structure, portable, and applicable to various scenarios. This foot deformity correction device is not only suitable for postoperative rehabilitation but also for daily exercise and intervention for patients with mild high arches.

[0046] In this embodiment, the base 1 may include: a support base 11, a support rod 12, and a crossbar 13 assembly;

[0047] Support base 11 is provided on both sides of the bottom of the base 1. The support base 11 is in contact with the ground to support the entire device and provide stability. Nuts 14 can be provided at the bottom of the support base 11 to adjust the height of the support base 11 and to adapt to uneven ground.

[0048] Support rod 12 is located at the bottom of the transverse central axis of the base 1, serving as the central support structure of the entire base 1;

[0049] The crossbar assembly includes two sets of crossbars, each set consisting of at least two parallel crossbars 13, with each end of the crossbar 13 connected to the support base 11 and the support rod 12 respectively; the two sets of crossbars are mirror-symmetrically distributed along the axial direction of the support rod 12, forming a left-right symmetrical structure; each pedal corresponds to a set of crossbars 13, and the pedal is disposed on the upper surface of the corresponding crossbar 13.

[0050] In this embodiment, refer to Figures 1-4 The pedal may include: a base 21, a pedal surface 22, and a transmission component 23;

[0051] The base 21 is slidably disposed on the upper surface of the crossbar 13 and can slide freely on the crossbar 13 to meet the needs of different users;

[0052] The pedal surface 22 is located on the upper part of the base 21. The side of the pedal surface 22 near the support rod 12 is hinged to the base 21, so that the pedal surface 22 can be adjusted in angle relative to the base 21.

[0053] Specifically, the upper surface of the pedal surface 22 is provided with an anti-slip structure to prevent the user's feet from slipping during use, thereby improving safety. The angle of the pedal surface 22 can be adjusted between 10° and 40° via a transmission component 23 between the base 21 and the pedal surface 22. The height of the support base 11 can also be adjusted via the nut 14 located at the bottom of the support base 11, thereby adjusting the angle of the pedal surface 22 and increasing the training load intensity.

[0054] The transmission component 23 is connected between the base 21 and the pedal surface 22 and is used to adjust the angle between the base 21 and the pedal surface 22.

[0055] By way of example and not limitation, the transmission component 23 may be a hydraulic cylinder, and the tilt angle of the pedal surface 22 may be adjusted by the extension and retraction of the hydraulic cylinder.

[0056] Furthermore, the pedal may also include a fixing bolt 24, disposed between the base 21 and the pedal surface 22, for fixing the angle between the base 21 and the pedal surface 22. Once the appropriate angle is achieved, the fixing bolt 24 locks the angle between the pedal surface 22 and the base 21, ensuring that the angle does not change during use.

[0057] In this embodiment, the pedal has an inner low and outer high structure, which can induce the patient's forefoot to produce abduction and eversion movements.

[0058] In this embodiment, the foot deformity correction device may further include: a connecting assembly, including two sets of connecting elements 3, each set of connecting elements 3 corresponding to one of the pedals, each set of connecting elements 3 including at least one connecting element 3, and the two ends of the connecting element 3 are respectively connected to the support rod 12 and the inner side of the pedal corresponding to the connecting element 3.

[0059] Specifically, each set of connecting elements 3 includes two connecting elements 3, and the two connecting elements 3 are arranged in parallel to provide a more stable connection and support.

[0060] Furthermore, one end of the connecting element 3 is connected to the side of the base 21 of the pedal near the support rod 12.

[0061] By way of example and not limitation, the connecting element 3 may be a spring element or a hydraulic cylinder. The connecting element 3 may consist of multiple replaceable / adjustable spring elements or multiple hydraulic cylinders to control the sliding resistance of the pedal, simulate different levels of muscle tension and resistance in patients, and achieve progressive rehabilitation training goals.

[0062] In this embodiment, a sliding pedal assembly 2 is used, combined with a spring element or hydraulic cylinder as a connecting element 3, to provide a foot rehabilitation training device with a reasonable structure, adjustable angle and training intensity, and good stability and safety. The feedback resistance is controlled by the spring or hydraulic cylinder, making the training more "active-passive synergistic," thereby promoting neuromuscular function reconstruction and foot alignment restoration. The pedal can slide on the support crossbar 13 via a guide rail, and the sliding range and direction are controlled by the connecting element 3.

[0063] In this embodiment, the foot deformity correction device may further include: a support rod 4, the bottom end of which is fixedly connected to one end of the support rod 12, the support rod 4 being perpendicular to the load-bearing surface of the base 1, and handles 41 provided on both sides of the top end of the support rod 4 to provide upper limb support for the patient and prevent falls during training.

[0064] In this embodiment, the structure of the support pole 4 and handle 41 reduces the dependence on medical staff, increases the patient's own participation, and helps to form a sustainable home rehabilitation mechanism.

[0065] Furthermore, the support pole 4 is provided with an adjustment buckle 42 for adjusting the height of the support pole 4. Users can adjust the height of the support pole 4 according to their own height to help them maintain body balance during training. This is especially suitable for patients with ataxia or muscle weakness to obtain the most comfortable user experience.

[0066] The working principle of the foot deformity correction device in this embodiment is as follows: The user stands on two pedals, with both feet placed on the two pedal surfaces 22 respectively. By adjusting the angle between the pedal surface 22 and the base 21, the pedal surface 22 is made into an inverted V shape, thereby correcting the user's foot. The pedals can slide on the crossbar 13 to adapt to different users' foot distances. The connecting element 3 can provide appropriate resistance or assistive force to help the user perform foot correction training. The user can maintain balance by holding the handle 41 at the top of the support rod 4. This application can indirectly affect the inversion state of the hindfoot by forcibly inducing the abduction and eversion of the forefoot. If the patient's hindfoot inversion is of the soft type, the hindfoot deformity can be improved by the traction action of the forefoot, achieving the purpose of rehabilitation training. This application simulates this principle and controls the feedback resistance through a spring or hydraulic cylinder, making the training more "active-passive synergistic", thereby promoting the reconstruction of neuromuscular function and the restoration of foot alignment.

[0067] As an example and not a limitation, in practical applications, the connecting element 3 of the foot deformity correction device uses a spring element, and the pedal and support rod 12 can be connected by a spring element. The spring element is of the weak elasticity type (tension of about 15N). The transmission component 23 inside the pedal can be spring-type, so that the pedal surface 22 is tilted inward and downward. The angle between the pedal surface 22 and the base 21 is 10°. The height of the support seat 11 is set to the lowest level to ensure stability. The armrest is adjusted to the height of the armpit to assist balance. It is suitable for the early postoperative rehabilitation stage. Training time: 2 times a day, 15 minutes each time, mainly passive sliding.

[0068] In practical applications, the pedal and support rod 12 can be connected by a hydraulic cylinder. The medium strength type (tension is about 25N) is used. The transmission component 23 inside the pedal can be a hydraulic cylinder. The angle between the pedal surface 22 and the base 21 is 30°. The support seat 11 can be raised 3 levels and its height can be adjusted by the bottom nut 14 structure of the support seat 11 to increase the traction strength of the foot. It is suitable for patients in the postoperative strengthening stage or with mild high arches. The handrail can be adjusted in height to maintain balance.

[0069] The foot deformity correction device of this application is equipped with adjustable handrails and safety limits to ensure stable support during training and reduce the risk of falls in children or early postoperative training; the height of the support seat 11 and the angle of the pedal are adjustable, making it suitable for children aged 3 and above to teenagers of different body types.

[0070] Compared with traditional high-arch foot rehabilitation methods (such as external fixation with plaster casts or simple insoles), this application has advantages in improving the hindfoot inversion angle, patient participation, and shortening the rehabilitation period. The table below is a comparison table (Table 1):

[0071] Table 1

[0072] Foot deformity correction device Traditional bracing method Improvement in hindfoot inversion Significant (average improvement >10°) Poor (<5°) Training cycle 6–10 weeks 10–16 weeks Patient active participation High (Self-regulation training) Low (passive orthopedics) cost Low high Security High (equipped with limit switches and handrails) generally

[0073] Example 2

[0074] The foot deformity correction device provided in this embodiment is basically the same as that in Embodiment 1. (See attached document for details.) Figure 5 As shown, the difference lies in the fact that connecting element 3 uses a hydraulic cylinder instead of a spring. A hydraulic cylinder provides more precise force control, allowing users to adjust the pressure according to their needs to achieve different correction effects. The use of a hydraulic cylinder also enables smoother resistance changes, avoiding sudden force changes that can occur with spring elements, thus improving user comfort and safety.

[0075] Example 3

[0076] The foot deformity correction device provided in this embodiment is basically the same as that in Embodiment 1, except that each set of crossbars consists of three parallel crossbars 13 instead of two. Increasing the number of crossbars 13 can improve the stability and load-bearing capacity of the entire device, making it suitable for heavier users. The design of three crossbars 13 can also reduce the stress on a single crossbar 13, extending the service life of the device.

[0077] Example 4

[0078] The foot deformity correction device provided in this embodiment is basically the same as that in Embodiment 1, except that the anti-slip structure on the upper surface of the footplate 22 uses a silicone anti-slip pad. The silicone anti-slip pad has good anti-slip performance and a comfortable feel, ensuring the user will not experience discomfort during prolonged use. The silicone anti-slip pad also provides cushioning, reducing pressure on the user's feet and improving comfort. The silicone anti-slip pad is easy to clean and replace, facilitating daily maintenance of the device.

[0079] Example 5

[0080] The foot deformity correction device provided in this embodiment is basically the same as that in Embodiment 1, except that the support pole 4 adopts a telescopic design, achieving height adjustment through a multi-segment telescopic tubular structure, rather than adjusting the height through the buckle 42. The telescopic design allows for a wider range of height adjustment, accommodating users of different heights. The telescopic support pole 4 is also smaller in size when retracted, facilitating the storage and transportation of the device.

[0081] Example 6

[0082] The foot deformity correction device provided in this embodiment is basically the same as that in Embodiment 1, except that the transmission component 23 between the pedal surface 22 and the base 21 is an electric hydraulic cylinder, which can precisely control the angle of the pedal surface 22 through an electronic control system. The electric hydraulic cylinder allows for more precise angle adjustment; the user can set the desired angle through the control panel without manual adjustment. The electric hydraulic cylinder can also be programmed to automatically adjust the angle of the pedal surface 22 according to a preset angle change pattern, achieving dynamic correction training.

[0083] Example 7

[0084] The foot deformity correction device provided in this embodiment is basically the same as that in Embodiment 1, except that an anti-slip pad and a leveling nut 14 are added to the bottom of the support base 11. The anti-slip pad increases the friction between the device and the ground, preventing the device from moving during use. The leveling nut 14 can adjust the levelness of the device, maintaining its stability even on uneven ground. The leveling nut 14 can be adjusted independently, ensuring that the device remains level in various ground conditions.

[0085] Example 8

[0086] The foot deformity correction device provided in this embodiment is basically the same as that in Embodiment 1, except that the handle 41 at the top of the support rod 4 is designed with an adjustable angle. The handle 41 can be adjusted according to the user's needs to obtain the most comfortable grip posture. The adjustable handle 41 can also be folded to reduce the space occupied by the device when not in use. The surface of the handle 41 is covered with a non-slip material to improve grip comfort and safety.

[0087] It should be noted that Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4, Embodiment 5, Embodiment 6, Embodiment 7, and Embodiment 8 are all types of foot deformity correction devices.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
