[0002] Due to their large amount of activity and potentially incorrect walking postures, children are prone to foot problems such as flat feet, pigeon toes, and paronychia. Therefore, in order to ensure the health of children's feet, the design of orthopedic insoles is particularly important. However, there are some problems in the existing technologies:

[0003] Firstly, the existing orthopedic insoles are insufficient in arch support and are difficult to provide sufficient support to help children form a correct arch structure, thus unable to effectively correct children's flat feet.

[0004] Secondly, the existing orthopedic insoles usually lack effective positioning of the toes and cannot fully reduce the friction and pressure between the toes caused by foot shape problems, and their function in preventing paronychia is relatively limited.

[0005] In addition, the existing orthopedic insoles cannot be dynamically adjusted according to different gait problems of children, resulting in unsatisfactory correction effects.

[0006] Therefore, there is an urgent need to design a 3D printed orthopedic insole facilitating rehabilitation that can solve the above technical problems. Summary of the Utility Model

[0007] Aiming at the problems mentioned in the background art, the purpose of the utility model is to provide a 3D printed orthopedic insole facilitating rehabilitation to solve the problems mentioned in the background art.

[0008] To achieve the above purpose, the utility model mainly provides the following technical solutions:

[0009] A 3D printed orthopedic insole facilitating rehabilitation, including a pad body, further including:

[0010] A gait guiding mechanism and an arch support mechanism; wherein:

[0011] The gait guiding mechanism includes a toe positioning groove opened on the upper wall of the flexible base layer, a cross-type toe strap movably installed on the periphery of the toe positioning groove, a vibration unit, a pressure sensor, and a battery fixedly installed on the upper wall of the gait guiding layer;

[0039] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. In addition, it should be noted that for the convenience of description, only the parts related to the utility model are shown in the drawings.

[0040] As Figures 1-5 shown, a 3D printed orthotic insole for facilitating rehabilitation of the present utility model includes a pad body 1, and further includes:

[0041] a gait guiding mechanism 2 and an arch support mechanism 3; wherein:

[0042] The gait guiding mechanism 2 includes a toe positioning groove 21 opened on the upper wall of the flexible base layer 11. The gait guiding mechanism 2 is mainly used to guide and correct the gait of children to prevent the problem of in-toeing. The toe positioning groove 21 can accurately limit the position of the toes to ensure that each toe maintains the correct posture during walking. A cross-type toe strap 22 is movably installed on the periphery of the toe positioning groove 21. The cross-type toe strap 22 is a detachable elastic band, and its position can be adjusted according to the size and shape of the child's foot to ensure the stability of the toes in the insole. A vibration unit 24, a pressure sensor 23 and a battery 25 are fixedly installed on the upper wall of the gait guiding layer 12. The battery 25 is used to provide power. The pressure sensor 23 can monitor the pressure distribution of the foot in real time and feedback it to the vibration unit 24. The vibration unit 24 prompts the user through vibration that the foot posture is improper to ensure that the orthotic insole can be dynamically adjusted and corrected according to the change of foot pressure;

[0043] The arch support mechanism 3 includes an airbag 31 arranged inside the flexible base layer 11 on the arch side. The airbag 31 can provide necessary support to correct the flat foot problem of children. A communicating through hole 32 is provided between the airbags 31. The through hole 32 can ensure the gas flow between the airbags 31. The pressure applied to the front sole and the heel makes the airbag 31 at the middle arch expand more to achieve a better support effect. An air hole 33 is opened on the inner wall of the airbag 31 at the innermost concave part on the arch side. The air hole 33 is used to inflate the airbag 31 or release excess gas to avoid too high or too low air pressure in the airbag 31 to ensure the comfort of the insole and the stability of the correction function. A rubber pad 34 is provided on the inner wall of the airbag 31 at the position of the air hole 33. The rubber pad 34 plays a sealing role.

[0044] As Figure 1 、 2As shown, in this embodiment, the toe positioning groove 21 is fixedly formed at the left end of the upper wall of the flexible base layer 11 to ensure that each toe is in the correct position within the insole, reducing toe friction or compression problems caused by improper postures. On the central part and the periphery of the lower wall of the flexible base layer 11, there are hook-and-loop fasteners with a rough surface 111, which ensure the detachable and replaceable nature of the flexible base layer 11. This enables users to easily clean or replace the flexible base layer 11, extending the service life of the insole while also ensuring the hygiene of the shoe interior environment.

[0045] As Figure 2 , 5 shown, in this embodiment, the cross-type toe strap 22 is movably installed at the left end of the flexible base layer 11, around the toe positioning groove 21. This position ensures that the cross-type toe strap 22 can restrain the toes in the correct position within the insole, effectively reducing toe slippage. At both ends of the cross-type toe strap 22, there are first hook-and-loop fasteners with a hook surface 221, which are adhesively connected to the hook-and-loop fasteners with a rough surface 111 on the periphery of the lower wall of the flexible base layer 11. The detachable cross-type toe strap 22 ensures that it can be adjusted according to the size of the child's foot, fully exerting its corrective function while achieving a stable fixation effect.

[0046] As Figure 4 shown, in this embodiment, the vibration unit 24 is fixedly installed in the middle of the left side of the upper wall of the gait guiding layer 12. The front sole closely adheres to the insole body 1 and has a relatively large area. This position can effectively transmit vibration signals, reminding the user to pay attention to the positions of their toes and soles, thereby helping the user adjust their gait and correct incorrect walking postures. On its right side, there are multiple pressure sensors 23 located around the middle of the upper wall of the gait guiding layer 12. These sensors can real-time monitor the pressure distribution of the foot and feedback the data to the vibration unit 24. A battery 25 is fixedly installed in the middle of the right side of the upper wall of the gait guiding layer 12.

[0047] As Figure 4 shown, in this embodiment, on the central part and the periphery of the upper wall of the gait guiding layer 12, there are second hook-and-loop fasteners with a hook surface 121, which can be adhesively connected to the hook-and-loop fasteners with a rough surface 111, thus realizing the detachable nature of the gait guiding layer 12.

[0048] As Figure 3 shown, in this embodiment, the number of air bags 31 is multiple and they are evenly distributed inside the flexible base layer 11 on the arch side. The multiple air bags 31 are evenly distributed, providing a raised inclined plane on the arch side, forcing the user to correct the in-toe posture. At the same time, the compression on the front sole and the heel causes more gas to accumulate at the arch, providing better support for the user's arch.

[0049] As Figure 3As shown, in this embodiment, the rubber pad 34 is annularly covered around the air holes 33 on the inner side wall of the airbag 31. After inflation is completed, the airbag 31 is filled with air, and the rubber pad 34 will shrink inward to block the air holes 33, preventing gas leakage, thereby maintaining the stable shape of the airbag 31.

[0050] As Figure 1 shown, in this embodiment, the upper surface of the flexible base layer 11 is made of a flexible and breathable polymer material, which can provide good comfort and breathability, can effectively remove the sweat on the feet, and keep the feet dry. The gait guiding layer 12 is made of a high-strength and wear-resistant material, which can withstand long-term wear and use, ensuring the durability and correction effect of the insole.

[0051] In this embodiment, the flexible base layer 11, the gait guiding layer 12, and the cross-shaped toe strap 22 are all made by 3D printing technology. 3D printing ensures the precise positioning of each component and the realization of its functions.

[0052] In this embodiment, the materials used in the 3D printing technology include any one or a combination of polyurethane, polylactic acid, nylon plastic, photosensitive resin, silicone, rubber, latex, ABS plastic, PVC plastic, silicone resin, and acrylic resin. The selection of materials is based on their unique performance advantages, giving full play to their performance advantages, and ensuring the overall functionality and durability of the insole.

[0053] The manufacturing process of a 3D printed orthopedic insole for facilitating rehabilitation of the present utility model is as follows: First, conduct a comprehensive examination of the patient's foot to evaluate the arch shape, gait characteristics, and other relevant orthopedic needs to determine the insole design parameters; then use a 3D scanner to scan the patient's sole to obtain 3D data of the sole, which will be used as the basis for customizing the insole to ensure a perfect fit with the patient's foot; immediately import the scanned 3D sole data into design software to generate a 3D model of the insole according to the patient's foot needs and orthopedic requirements; then select a suitable 3D printing material according to the design requirements and the actual needs of the patient to ensure the comfort and durability of the insole; finally, use a 3D printer to print out the designed insole model. After printing, perform necessary post-processing on the insole, such as surface treatment, flexible adjustment, etc., and make fine adjustments according to the patient's feedback to finally form an orthopedic insole finished product suitable for the patient.

[0054] The working principle and usage process of this technical solution are as follows: During use, first fill the airbag 31 with air through the air holes 33, attach the cross-type toe strap 22 to the appropriate position, then attach the gait guiding layer 12 under the flexible base layer 11, and then put the insole into the shoe. The combination of the toe positioning groove 21 and the cross-type toe strap 22 can fix the toe position, reducing friction and pressure caused by improper toe position. When the user walks, according to the user's foot shape, the arch support mechanism 3 will change dynamically to fit the user's foot sole. The pressure sensor 23 in the gait guiding mechanism 2 will monitor the pressure distribution of the foot in real time. When an incorrect foot posture is maintained for a long time and the pressure distribution is unreasonable, the vibration unit 24 will remind the user to adjust the gait to ensure the effect of gait correction.

[0055] The above describes the present utility model in further detail in combination with the embodiments, but the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by ordinary technicians in the art, various changes can be made without departing from the purpose of the present utility model.
