Description

Technical Field

[0001] This utility model belongs to the field of orthopedic medical device technology, and in particular relates to a hallux valgus correction insole. Background Technology

[0002] Hallux valgus is a common foot deformity, specifically defined as a tilt of the joint between the big toe and the first metatarsal bone exceeding 15 degrees. Hallux valgus is caused by various factors, such as genetics, frequently wearing high heels or pointed shoes, which cause the big toe to turn excessively outward. Additionally, people with flat feet are more prone to developing hallux valgus. To prevent the condition from worsening and to avoid complications, doctors may recommend that patients wear hallux valgus braces to relieve tension in the lateral ligaments of the big toe and help reduce pulling pain on the outer side of the toe.

[0003] Clinical statistics show that many patients with hallux valgus also experience painful calluses below the second metatarsal head. The metatarsal head compresses the plantar nerve, causing plantar pain. This is due to strain on the transverse arch of the forefoot, with compression or irritation of the plantar nerve leading to discomfort and pain in the metatarsal shafts and plantar surfaces of the metatarsal heads (i.e., the sole of the forefoot). However, simple hallux valgus correctors cannot relieve metatarsalgia. When bearing weight, patients experience pain not only in the bunion area due to hallux valgus but also in the area below the second and third metatarsal heads due to metatarsalgia. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a hallux valgus correction insole that improves hallux valgus while reducing the pain caused by metatarsalgia.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A hallux valgus correction insole is provided, including a foot-shaped sole, on which a hallux valgus correction sleeve and a metatarsal pad are provided. The hallux valgus correction sleeve includes: a dorsum strap, both ends of which are connected to the two sides of the foot-shaped sole to form a cavity for accommodating the patient's foot; a big toe sock, located at the front end of the dorsum strap corresponding to the patient's big toe, with an inner cavity size matching the big toe size, and a plurality of fastening buckles on one side of the big toe sock; a traction strap, one end of which is connected to the side of the dorsum strap away from the big toe sock, and the other end of which has a buckle that matches the fastening buckles; the metatarsal pad includes a silicone pad located on the foot-shaped sole, at the arch of the foot.

[0006] Preferably, the silicone pad is teardrop-shaped, with the larger end facing the toe tip.

[0007] Preferably, the silicone pad is disposed on the side of the foot-shaped sole pad facing the instep strap.

[0008] Preferably, the instep strap has several ventilation holes.

[0009] Preferably, the number of fixing buckles is three.

[0010] Preferably, the traction band has a through hole at the heel position.

[0011] The beneficial effects are as follows: This invention adds a hallux valgus traction strap and a metatarsalgia pad to the insole, reducing the size of the support and avoiding bulkiness. It can be worn inside the shoe to facilitate weight-bearing walking and is easy to put on. It can simultaneously improve the symptoms of hallux valgus and metatarsalgia, and reduce the patient's pain. For hallux valgus patients with metatarsalgia, this invention can achieve satisfactory clinical results. Attached Figure Description

[0013] Among them, 1-foot-shaped insole; 101-ventilation hole; 2-foot instep strap; 3-big toe sock; 301-fixing buckle; 4-traction strap; 401-fastener; 5-silicone pad. Detailed Implementation

[0014] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0015] like Figure 1 As shown, this utility model provides a hallux valgus correction insole (the left insole is shown in the figure; the right insole is symmetrical and not shown). It includes a foot-shaped base 1, on which a hallux valgus correction sleeve and a metatarsal pad are provided. The hallux valgus correction sleeve includes a dorsal foot strap 2, a big toe sock 3, a traction strap 4, and a metatarsal pad. The two ends of the dorsal foot strap 2 are connected to the two sides of the foot-shaped base 1, forming a cavity to accommodate the patient's foot. The big toe sock 3 is located at the front end of the dorsal foot strap 2 corresponding to the patient's big toe, and its inner cavity size matches the big toe size. A plurality of fixing buckles 301 are provided on one side of the big toe sock 3. One end of the traction strap 4 is connected to the side of the dorsal foot strap 2 away from the big toe sock 3, and the other end has a buckle 401 that matches the fixing buckles 301. The metatarsal pad includes a silicone pad 5 located on the foot-shaped base 1 at the arch of the foot.

[0016] In one specific embodiment, the silicone pad 5 is teardrop-shaped, with the larger end facing the toe tip. When worn, it is positioned in front of the metatarsal bones to transfer pressure from the painful area. Simultaneously, by altering the pressure distribution in the foot, the metatarsal pad can help correct abnormal gait, making the pressure on different parts of the foot more even and reducing pain and injury caused by uneven pressure. The silicone pad 5 is located on the side of the foot-shaped sole pad 1 facing the instep strap 2, directly contacting the patient's sole. Because it is made of silicone, the metatarsal pad has excellent cushioning properties, reducing the impact of ground reaction forces on the foot during walking or exercise, thereby alleviating pain.

[0017] In one specific embodiment, the instep strap 2 is an elastic band made of latex. When worn by the patient, it fits snugly on the instep to prevent the foot from slipping on the insole. The instep strap 2 has several ventilation holes 101 for breathability.

[0018] In one specific embodiment, the traction band 4 is a long strip with a through hole in its middle section. After the band is worn, the through hole should correspond to the heel position to prevent the patient from experiencing skin damage due to prolonged friction with the heel while wearing and walking.

[0019] In one specific embodiment, the bottom of the big toe sock 3 is not connected to the foot-shaped pad 1 to prevent the foot-shaped pad 1 from shifting when the big toe sock 3 is pulled by the pull strap 4.

[0020] In a kind of Figure 1 In the specific embodiment shown, there are three fixing buckles 301, arranged sequentially along the length of the big toe sock 3. The fixing buckle 301 is a semi-circular buckle groove, and the hook 401 is a rigid plastic hook. In use, the hook of the hook 401 is inserted into the fixing buckle 301 to complete the connection.

[0021] The following details the method of using this utility model: When using it, the patient puts the affected foot into the cavity formed by the instep strap 2 and the foot-shaped insole 1, and puts the big toe of the affected foot into the big toe sock 3. After the traction strap 4 is wrapped around the heel from behind the heel, the buckle 401 is fastened to different of the fixing buckles 301 according to the distance that the big toe needs to be pulled. After confirming that the wearing and connection are stable, the entire affected foot is put into the shoe without the need for an additional insole.
