Hallux valgus deformity refers to the lateral deflection of the hallux at the first metatarsophalangeal joint, which is a complex anatomical deformity and is extremely challenging to treat. The treatment mode of hallux valgus is divided into traditional operation and minimally invasive operation, wherein the traditional operation commonly used for treating hallux valgus comprises soft tissue operation and osteotomy operation, the operation needs to make an incision at or around the thumb, peel off tissues such as skin, joint capsule and nerve, and excise osteophyte, synovial capsule or perform osteotomy, thereby achieving the purposes of correcting deformity and relieving pain.
The minimally invasive surgery is a surgery method appearing in recent years, the minimally invasive surgery mode is suitable for hallux valgus with various degrees, local infiltration anesthesia or combined block anesthesia is needed to be carried out on the foot of a patient during the minimally invasive surgery, and then an incision is made on the inner side of the 1 st metatarsal head to excise osteophytes; after the minimally invasive surgery is completed, a toe pad is additionally arranged between the 1 st and 2 nd toe webs, and the 1 st metatarsal bone is fixed by bandaging. However, the use of a toe-separating pad in combination with a bandage has the following problems: 1. the bandage corrects the eversion position of the first metatarsal by means of the wrapping force, the sole is sore when the wrapping force is too large, and the correction cannot be achieved when the wrapping force is too small; 2. although the toe separating pad can utilize the interaction force between the 1 st and 2 nd toe webs to support the big foot bone outwards, the 1 st metatarsal eversion part lacks the corresponding correction force.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the utility model designs a minimally invasive auxiliary brace for hallux valgus, which utilizes the force couple principle to correct the 1 st metatarsal valgus, can also correct the 1 st metatarsal inwards while supporting the phalanges outwards, and prevents the relapse of hallux valgus in the postoperative rehabilitation process; this brace formula structure as an organic whole, the postoperative is used and is changed very conveniently.
In order to achieve the technical effects, the utility model discloses a following technical scheme realizes:
the minimally invasive hallux valgus auxiliary brace comprises a toe-separating clamping block, a connecting part, a fitting part and a restraining block, wherein the toe-separating clamping block is fixedly connected with the connecting part, the connecting part is fixedly connected with the fitting part, the fitting part is fixedly connected with the restraining block, a first clamping groove and a second clamping groove are respectively arranged on two sides of the toe-separating clamping block, the connecting part and the fitting part are in a sheet shape, the fitting part is in arc-shaped transition and then is fixedly connected with the restraining block, and a third clamping groove is arranged on the inner side of the restraining block. The toe separating clamping block and the constraint block are arranged in parallel, the attaching part and the constraint block are arranged vertically, and the attaching part and the connecting part are arranged vertically.
Furthermore, the minimally invasive hallux valgus auxiliary brace is integrally formed by the toe separating clamping block, the connecting part, the fitting part and the restraining block.
Furthermore, the toe separating clamping block, the connecting part, the attaching part and the restraining block are all made of latex materials.
The utility model has the advantages that: the brace corrects the 1 st metatarsal eversion by utilizing the force couple principle, can correct the 1 st metatarsal inwards while supporting the phalanges outwards, and prevents the problem of relapse of the hallux eversion in the postoperative rehabilitation process; the bone fracture stabilizing agent is used for stabilizing bone fracture and preventing displacement after osteotomy; this brace formula structure as an organic whole, the postoperative is used and is changed very conveniently.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1-2, the minimally invasive hallux valgus auxiliary brace is formed by integrally molding a toe separating clamping block 1, a connecting part 2, a fitting part 3 and a restraining block 4, wherein the toe separating clamping block 1, the connecting part 2, the fitting part 3 and the restraining block 4 are all made of latex materials. Divide toe clamp splice 1 in connecting portion 2 fixed connection, connecting portion 2 and the 3 fixed connection of laminating portion, laminating portion 3 and about piece 4 fixed connection, the both sides of dividing toe clamp splice 1 be equipped with first clamp groove 11 and second clamp groove 12 respectively, connecting portion 2 and laminating portion 3 are the slice, the left side of laminating portion 3 is arch and arc transition back and about piece 4 fixed connection, about piece 4's inboard is equipped with third clamp groove 41.
Wherein, divide toe clamp splice 1 and restraint piece 4 parallel arrangement, laminating portion 3 sets up with restraint piece 4 looks vertically, laminating portion 3 sets up with connecting portion 2 looks vertically.
As shown in fig. 3, which is a using state diagram of the brace on the hallux valgus of the left foot, in the figure, the toe-divided clamping block 1 is placed between the 1 st and 2 nd phalanges, and the 1 st phalange and the 2 nd phalange are respectively clung to the cambered surfaces of the second clamping groove 12 and the first clamping groove 12; the connecting part 2 extends to the back of the 1 st and 2 nd toe webs and is attached to the dorsum of the foot, the attaching part 3 straddles over the 1 st metatarsal, and the third clamping groove 41 of the restraint block 4 is closely attached to the skin on the outer side of the 1 st metatarsal. Because the patient is hallux valgus, the magnitude of the acting force F 'applied to the 2 nd phalange by the 1 st phalange is larger than that of the acting force F generated by the 2 nd phalange, the 2 nd phalange is pushed to the right, the support generates a force couple M and rotates anticlockwise under the action of the force couple M, the lower edge of the restraint block 4 is tightly attached to the 1 st metatarsal, the 1 st metatarsal generates a force F2 (F' -F) to the restraint block 4, the support reaches a balance state, the 1 st metatarsal is corrected inwards under the support of the restraint block 4, and the 1 st phalange is corrected outwards under the correction of the split-toe clamp block 1, so that the 1 st phalange is kept in a vertical state as much as possible, and the problems of displacement and relapse of hallux valgus are prevented.
The minimally invasive hallux valgus auxiliary brace shown in fig. 1 is subjected to mirror symmetry, and the manufactured brace can be used for minimally invasive postoperative auxiliary fixation of right foot hallux valgus.
