Description

How to make corrective foot pads

The present invention relates to a method of making a corrective foot pad, and in particular to a method of making a corrective foot pad using a foot shape mold.

Foot deformity refers to the abnormal shape or structure of the foot, including flat feet, varus feet, valgus feet, drop feet, heel feet and other different types of foot deformities. It can be caused by congenital foot defects or secondary diseases. caused by reasons. When the symptoms of foot deformity occur, it will affect the human body's standing posture and increase the weight of the foot, and lead to abnormal gait such as lameness, causing calluses or pressure sores on the instep, sole or heel due to friction, and even worse. It may cause tendonitis or osteomyelitis, affecting the patient's health status and quality of life.

In terms of correction of foot deformity, mild foot deformity is usually corrected by physical correction, allowing the patient to undergo rehabilitation treatment with the assistance of protective gear or other auxiliary tools, while severe foot deformity requires Surgical treatment is required, and protective gear and other auxiliary tools must be worn after surgery to maintain the normal shape and position of the foot. However, foot deformity is mostly corrected by doctors or physical therapists based on experience, and the accuracy of the correction remains to be evaluated. Furthermore, the protective gear and auxiliary tools used to correct foot deformities are relatively expensive and difficult to obtain. They are also difficult to use and bulky in appearance, making it difficult to use conventional protective gear and auxiliary tools. Correction of foot deformity has its inconveniences.

In order to solve the above problems, a variety of different orthotic pads have appeared on the market, including arch pads, forefoot pads or heel pads. The corrective pads can be placed in shoes corresponding to the parts of the foot where deformities occur to correct the foot. Compared with conventional protective gear and auxiliary tools, orthotic pads are low-priced, lightweight and easy to obtain, making them popular in the market. However, using orthotic pads to correct foot deformities cannot ensure that the long axis of the Achilles tendon of the user's foot and the long axis of the calcaneus can be completely aligned. This may cause the user to have the sole of the foot touch the ground. Under such circumstances, the best correction effect cannot be achieved. Furthermore, the aforementioned correction pads are easily displaced due to external forces when the user walks, or the size and thickness of the correction pads cannot meet the needs of different users, thereby affecting the accuracy of foot correction and reducing the cost of correction. s efficiency.

In order to solve the above problems, some manufacturers are customizing the production of corrective foot pads for a single user. When making customized corrective foot pads, the user's feet must first be inspected and adjusted to obtain a foot-shaped template that fits the user's foot shape, and then the foot-shaped template is used to mold and manufacture the foot pads. Although the orthopedic foot pad produced by the above method can meet the needs of different users, it requires the molding of a single user's foot shape, and the manufacturing cost of the foot pad is relatively high. Furthermore, the process from obtaining the foot template to completing the production of the orthotic foot pad usually takes several days, so that the manufacturing efficiency of the customized orthotic foot pad is relatively inefficient.

Therefore, how to make customized orthopedic foot pads suitable for different users in a fast, accurate and low-cost manner to improve the applicability and correction efficiency of the orthopedic foot pads has become a development goal of the relevant academic circles and industry.

The above summary of the invention is intended to provide a simplified summary of the content disclosed in the invention so that readers can have a basic understanding of the content disclosed in the invention. The above summary of the invention is not a complete summary of what is disclosed. It is not intended to identify important or critical elements of the invention, nor is it intended to limit or define the scope of the invention.

Several embodiments of the present invention will be described below with reference to the drawings. For the sake of clarity, many practical details will be explained together in the following narrative. However, it will be understood that these practical details should not limit the invention. That is to say, in some embodiments of the present invention, these practical details are not necessarily described in detail. In addition, in order to simplify the drawings, some commonly used structures and components are shown in the drawings in a simple schematic manner.

Please refer to FIG. 1 , which is a step flow chart of a method S10 for manufacturing a corrective foot pad according to an embodiment of the present invention. The manufacturing method S10 of the orthotic foot pad includes step S11, step S12, step S13 and step S14.

Step S11 is a detection step, which involves making a subject's foot step on a foot shape mold to obtain a corrected front foot shape. The pre-corrected foot shape can truly reflect the structure and shape of the subject's foot and serve as a basis for subsequent comparison and adjustment. The pre-corrected foot shape includes a plurality of detected curved surfaces, and the corresponding long axis of the calcaneus and the distance between the foot and the foot. The long axes of the Achilles tendon are not collinear. Specifically, the sole of the foot shape before correction is composed of a plurality of detection curved surfaces. The detection curved surface represents the configuration and state of the subject's sole before correction, and the corresponding calcaneus of the subject's foot The relative relationship between the long axis and the long axis of the Achilles tendon of the foot represents whether the force exerted by the subject's legs on the foot is even. Specifically, when the long axis of the calcaneus corresponding to the foot is collinear with the long axis of the Achilles tendon of the foot, the long axis of the subject's leg will be vertical to the ground, and the weight of the leg will be equally exerted at this time. In the foot, it means that the subject does not suffer from foot deformity, and when the long axis of the calcaneus corresponding to the foot and the long axis of the Achilles tendon of the foot are not collinear, it means that the Achilles tendon will be deformed due to the turning of the foot. It is tilted or twisted rather than in a straight state, which makes the subject prone to discomfort and pain when walking and moving, and symptoms of foot deformity occur.

Step S12 is an evaluation and adjustment step, which is to determine an abnormal block characteristic of the detected curved surface of the foot shape before correction, where the abnormal block characteristics include an abnormal block number and an abnormal block position, and the evaluation and adjustment step is to adjust The long axis of the calcaneus corresponding to the foot is collinear with the long axis of the Achilles tendon of the foot. After confirming whether the long axis of the calcaneus and the long axis of the Achilles tendon of the foot are collinear, use a pair of Obtain a corrected foot shape. Specifically, the corrected forefoot shape can be compared with the foot configuration in the natural state of a normal foot without foot deformity. When the corrected forefoot shape is consistent with the foot configuration in the natural state, the corrected forefoot shape is The multiple detected curved surfaces of the sole of the foot will respectively correspond to the normal curved surface of the foot configuration in the natural state. On the contrary, if the subject is a patient with monopodia, at least one detected curved surface of the sole of the corrected forefoot shape will not correspond to one of the normal curved surfaces, nor will it show the same pressure distribution pattern, and the aforementioned non-corresponding parts This is the abnormal block characteristic described above. The abnormal block characteristics can reflect the abnormal parts of the subject's foot, and the number and location distribution of the abnormal blocks can be used to determine the type of foot deformity in the subject's foot for subsequent correction. Furthermore, the assessment and adjustment steps can be adjusted according to the skew angle of the subject's long axis of the calcaneus and the long axis of the Achilles tendon of the foot, and the alignment of the long axis of the calcaneus and the long axis of the Achilles tendon of the foot can be confirmed with a pair of optics. The long axes of the Reese's tendons are aligned to obtain the correct corrected hindfoot shape.

Step S13 is a comparison and analysis step, which involves overlapping and comparing the pre-corrected foot shape and the post-correction foot shape. The post-correction foot shape includes a plurality of corrected curved surfaces, and the post-correction foot shape is at a position of the foot shape mold and the pre-corrected foot shape. The position of the foot shape mold is overlapped to determine an abnormal area between each corrected curved surface of the corrected foot shape and a plurality of detected curved surfaces of the pre-corrected foot shape before and after correction. Specifically, when the non-abnormal areas of the corrected front foot shape coincide with the corrected foot shape, the multiple corrected curved surfaces of the sole of the corrected foot shape will respectively correspond to the multiple detected curved surfaces of the corrected front foot shape. At this time, comparison analysis The step will further determine the corrected curved surface of the sole of the foot after correction and its corresponding detected curved surface to accurately determine the abnormal areas before and after correction to facilitate subsequent steps.

Step S14 is a foot pad pressing step, which is to capture an outline of the corrected foot shape as a sole model, and place at least one support member on a foot pad corresponding to at least one abnormal area to form a corrected foot pad. . In detail, the number of abnormal blocks and the position of the abnormal blocks are the positions that need to be corrected based on the natural foot configuration of the subject, and placing at least one support member on the foot pad corresponds to the abnormal blocks before and after correction. It can help the subject's foot maintain the corrected state, so that the corrective foot pad made according to the corrected foot shape can effectively comply with the adjustment results of the subject's foot, so as to facilitate the subsequent obtaining of the correct corrective foot pad. . Furthermore, the support member can be connected to the footpad through adhesive means or thermoplastic means, and the invention is not limited thereto. Furthermore, the support member can be made of elastomer material, and its shape and size can also be adjusted according to the types of foot deformity of different subjects' feet, so that the adjustment margin for correction can be greatly improved.

Please refer to Figures 2, 3 and 4. Figure 2 is a step flow chart illustrating the method S20 for making a corrective foot pad according to another embodiment of the present invention.

One mold space 125. Specifically, when one of the subjects' feet steps on the stepping surface 123, each telescopic rod 120 will be displaced in response to a stepping force of the foot and form a foot-shaped mold cavity 1231 on the stepping surface 123 (marked in Figure 6) .

The positioning member 130 is provided on the base 110 and is used to position the telescopic rod 120 so that the telescopic rod 120 can still maintain its position after the force exerted by the foot is removed for subsequent image capture and judgment. .

The support member 150 is detachably disposed in the mold space 125, and the support member 150 may be made of an elastomer material, but the invention is not limited thereto.

Schematic diagram of the adjustment of the long axes L2 and L4 of the calcaneus and the long axes L1 and L3 of the Achilles tendon of the foot when correcting flat feet.

Flatfoot is a common foot deformity. The sole of a normal person's foot presents a natural arch, which is the arch of the sole of the foot. When the human body is walking or running, the arch of the foot will provide appropriate elasticity and torsion according to various terrains to achieve the purpose of shock absorption and balance. However, patients with flat feet have very obvious arches or almost no arches. When they stand or step flat on the ground, the arches on the inside of the soles of the feet will sink, and the soles of the feet will become flat, even flat against the ground, so that There will be a feeling of discomfort, or even pain, which will affect normal walking. The foot mold 100 and the contents of Figures 2 to 8 will be used below to explain more clearly the method S20 of manufacturing the corrective foot pad of the present invention.

Step S22 is a first stepping step, which involves releasing the plurality of telescopic rods 120 to allow the foot to step on the treading surface 123 for the first time, so as to form a first foot-shaped mold cavity 1231 on the treading surface 123 .

Step S23 is a first capturing step, which uses the positioning member 130 to fix the plurality of telescopic rods 120 to fix the first foot-shaped mold cavity 1231, and uses the image capturing device 140 to capture one of the first foot-shaped mold cavities 1231. Three-dimensional images are used to obtain a corrected forefoot shape (not shown in the figure), in which the corrected forefoot shape includes a plurality of detection curved surfaces, and a corresponding long axis of the calcaneus L2 and a long axis of the Achilles tendon of the foot L1 Not collinear.

Specifically, when the method S20 for making a corrective foot pad of the present invention is used to prepare a corrective foot pad for correcting flat feet, as shown in Figure 5, when a subject suffering from flat feet steps on the foot pad, When the surface 123 is reached, the first end 121 of the telescopic rod 120 will abut against the surface of the foot, causing the telescopic rod 120 to displace according to different stress levels, and the second end 122 of the telescopic rod 120 will also move due to the force exerted by the foot. By stepping on it, you can move to different degrees. Next, as shown in Figure 6, after the telescopic rods 120 are positioned using the positioning member 130, even if the subject's feet leave the stepping surface 123, each telescopic rod 120 can still maintain its displacement position after receiving force. , thereby fixing the first foot-shaped mold cavity 1231. At this time, the image capturing device 140 will further capture the three-dimensional image of the foot-shaped mold cavity 1231 for subsequent analysis.

Step S24 is an evaluation step, which uses the computing module to analyze the corrected forefoot shape to obtain an abnormal block characteristic of a plurality of detected curved surfaces of the corrected forefoot shape, where the abnormal block characteristics include an abnormal block number and an abnormal block characteristic. Abnormal block positions, and the evaluation step is to obtain a placement position of at least one support member 150 in the mold space 125 based on the number of abnormal blocks and the abnormal block positions. Specifically, as shown in Figure 6, the computing module will analyze the three-dimensional image of the foot shape mold cavity 1231 captured by the image capture device 140 to determine whether the foot shape before correction coincides with the foot configuration in the natural state. When correcting the abnormal area that cannot correspond between at least one detected curved surface of the sole of the forefoot and the corresponding normal curved surface of the foot configuration in the natural state. Furthermore, as shown in Figure 7 , when the method S20 for making a corrective foot pad of the present invention is used to prepare a corrective foot pad for correcting flat feet, the abnormality of the arch of the subject's foot analyzed by the calculation module is confirmed. After determining the severity of the flatfoot condition, an appropriately sized and shaped support member 150 is placed in the mold space 125 of the foot mold 100 relative to the arch of the flatfoot foot.

Step S25 is to perform a second step of adjusting and stepping, which is to release the positioning member 130 to reset the plurality of telescopic rods 120, and to make the foot step on the stepping surface 123 a second time to form a second foot-shaped mold cavity (not shown in the figure). As shown in the figure), a position where the foot performs the second step on the tread surface 123 coincides with a position where the foot performs the first step on the tread surface 123 . Specifically, after the evaluation step, the subject's foot will step on the stepping surface 123 again. At this time, the plurality of telescopic rods 120 relative to the position of the arch will move upward due to the change in the body shape of the foot. Elevate the subject's arch. As shown in Figure 8, the long axis L2 of the calcaneus corresponding to the corrected foot and the long axis L1 of the Achilles tendon of the precorrected foot are non-collinear (as shown by the dotted line). After correction, the corresponding long axis of the foot The long axis L4 of the calcaneus and the long axis L3 of the Achilles tendon of the foot will be corrected from the non-collinear state before correction to the collinear state. In other words, the skew angles of the corresponding long axes L2 and L4 of the calcaneus and the long axes L1 and L3 of the Achilles tendon of the foot will be corrected at the same time. In addition, the operation mode of the foot-shaped mold 100 is the same as that of the first stepping step and the stepping mode. The only difference is that the second adjusting stepping step is used to capture the second foot-shaped mold cavity. The relevant operating methods are here. No more details.

Step S26 is a second capturing step, which uses the positioning member 130 to fix the telescopic rod 120 to fix the second foot-shaped mold cavity, and uses the image capturing device 140 to capture a three-dimensional image of the second foot-shaped mold cavity, so as to Obtain a corrected foot shape. The operation method of the second capturing step on the foot mold 100 is the same as that of the first capturing step. The only difference is that the second capturing step is used to capture the three-dimensional image of the second foot mold cavity and further obtain the corrected foot shape. The relevant operation methods will not be described again here.

Step S27 is an analysis step in which the pre-corrected foot shape and the post-correction foot shape are overlapped and compared, and the computing module is used to determine an abnormality between the detected curved surface of the pre-corrected foot shape and the post-correction foot shape before and after correction. block to obtain multiple corrected curved surfaces of the corrected foot shape.

Step S28 is a step of making a foot pad, which involves placing at least one support member 150 into the mold space 125 at a position corresponding to the corrected curved surface, to obtain a foot pad model 1241 corresponding to the model surface 124, and translate the foot pad model 1241 to A foot pad material (not shown) is used to form a corrective foot pad.
