Description

A hallux valgus corrector Technical Field

[0001] This patent relates to the field of medical devices, and specifically to a hallux valgus corrector. Background Art

[0002] Currently, the invention includes a metatarsal support, a big toe support, a big toe wearing piece provided on the big toe support, and a foot wearing piece provided on the metatarsal support. A correction adjustment component for adjusting the angle of the big toe support is installed on the metatarsal support. The traction end of the correction adjustment component is connected to the big toe support. The metatarsal support and the big toe support are rotatably connected via a rotating shaft. The big toe support is rotated by the correction adjustment component to pull the big toe for correction. The part where the metatarsal support contacts the metatarsophalangeal joint is the metatarsophalangeal joint support part. When a person walks, the metatarsophalangeal joint is in a state of rotation and movement, and friction occurs between the metatarsophalangeal joint and the metatarsophalangeal joint support part, which causes the skin at the metatarsophalangeal joint to easily rub and blister or calluses. Technical issues

[0003] The purpose of this patent is to solve the problem that the metatarsophalangeal joint support part of the existing hallux valgus corrector is prone to friction and blistering at the metatarsophalangeal joint. Technical Solutions

[0004] The hallux valgus corrector of this patent includes a metatarsal support, a big toe support, a big toe wearable device mounted on the big toe support, and a sole wearable device mounted on the metatarsal support. The metatarsal support is mounted with an adjustment assembly for adjusting the angle of the big toe support. The traction end of the adjustment assembly is connected to the big toe support. The metatarsal support is provided with a round metatarsophalangeal joint support portion corresponding to the metatarsophalangeal joint. The metatarsophalangeal joint support portion is movably connected to the metatarsal support and is provided with a soft cushion. Beneficial effects

[0005] When using this patented hallux valgus corrector, the sole wearer is placed on the sole of the foot and the big toe wearer is placed on the thumb. The angle of the big toe support is adjusted using the correction adjustment assembly. The metatarsophalangeal joint support is circular and rotatably connected to the metatarsal support. A soft cushion is provided on the metatarsophalangeal joint support. When walking, the metatarsophalangeal joint support rotates with the movement of the metatarsophalangeal joint, eliminating friction with the joint and preventing damage to the joint, resulting in a comfortable wear.

A correction adjustment component 5 for adjusting the angle of the big toe support is installed on the metatarsal support. The traction end of the correction adjustment component is connected to the big toe support. A metatarsophalangeal joint support portion 6 is provided on the metatarsal support 1 at the corresponding metatarsophalangeal joint. The metatarsophalangeal joint support portion is circular and is movably and rotatably connected to the metatarsal support. A soft pad 7 is provided on the metatarsophalangeal joint support portion. During use, the sole wearable component is placed on the sole of the foot, and the big toe wearable component is placed on the thumb. The angle of the big toe support component is adjusted using the correction adjustment assembly. The metatarsophalangeal joint support component is circular and rotatably connected to the metatarsal support component. The metatarsophalangeal joint support component is provided with a soft pad. When walking, the metatarsophalangeal joint support component rotates with the movement of the metatarsophalangeal joint, thereby avoiding friction with the metatarsophalangeal joint and preventing friction damage to the metatarsophalangeal joint, thereby providing a comfortable wear. In this embodiment, the soft pad is a silicone pad. When walking, the silicone pad contacts the metatarsophalangeal joint, providing a comfortable feeling.

A first rotating shaft buckle 62 is provided at the bottom of the first rotating shaft, which engages with the bottom of the first sleeve. During installation, the first rotating shaft is inserted into the first sleeve, and the first rotating shaft buckle engages with the bottom of the first sleeve, making installation simple and convenient. The metatarsal support member is provided with a metatarsophalangeal joint support mounting groove that mates with the metatarsophalangeal joint support portion, and the metatarsophalangeal joint support portion rotates within the metatarsophalangeal joint support groove.

[0012] In this embodiment, the metatarsal support member 1 includes a metatarsal support body 12 and a connecting portion 13 fixedly connected to the metatarsal support body. The connecting portion is fixedly connected to the metatarsal support body via a buckle. The metatarsophalangeal joint support portion is located on the side of the metatarsal support body closer to the foot. The connecting portion is connected to the side of the metatarsal support body farther from the foot. The big toe support member is connected to the connecting portion. A second sleeve 131 with a notch is provided on the connecting portion 13. The big toe support member 2 is provided with a second rotating shaft 21 that mates with the second sleeve. The big toe support member is rotatably connected to the connecting portion. During use, the second rotating shaft is directly inserted into the second sleeve, making installation simple and convenient, and manufacturing is easy and simple. In this embodiment, a second buckle 22 is provided on the second rotating shaft 21 to prevent the second rotating shaft from falling out of the second sleeve. The second buckle is arranged concentrically with the second rotating shaft, and a slot 132 is provided in the second sleeve 131 to mate with the second buckle. When the second rotating shaft is inserted into the second shaft sleeve, the second rotating shaft is positioned in the slot by the second buckle. When the second rotating shaft rotates, the second buckle rotates in the slot to prevent the second rotating shaft from moving out of position.

[0013] In this embodiment, the orthotic adjustment assembly 5 includes an adjustment strap 51, an adjustment strap fixing square slot frame 52 provided on the connector, and an adjustment strap support square slot frame 53 provided on the big toe support.
