[0001] The invention belongs to the technical field of medical auxiliary devices, and in particular relates to a fixing device for assisting hallux valgus osteotomy. Background Art
[0002] Hallux valgus osteotomy is a common surgical method for treating hallux valgus. Hallux valgus is a common foot deformity, which is usually manifested by the big toe (big toe) deviating to the outside and the first metatarsal (the large bone on the inside of the sole of the foot) protruding inward, forming a noticeable bone protrusion. This deformity is often accompanied by pain and limited movement, especially when wearing shoes, which often causes discomfort or even inflammation. The purpose of the surgery is to correct hallux valgus, relieve pain, and improve foot function and appearance. After the surgery, a fixation device is needed to protect the big toe and metatarsophalangeal joint.

[0022] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0023] Embodiment 1
[0024] See also Figure 1-4 The present invention is a fixing device for assisting hallux valgus osteotomy, comprising a placing plate 15, one side of which is fixedly connected to a shell 2; a fixing assembly is arranged inside the shell 2, the fixing assembly comprises an isolation plate 3, the isolation plate 3 is fixedly connected to the top of the inner cavity of the shell 2, the top of the isolation plate 3 is rotatably connected to a rotating rod 4, the surface of the rotating rod 4 is fixedly connected to a gear 5, fixing plates 1 are arranged on both sides of the inner cavity of the shell 2, one side of the fixing plate 1 is fixedly connected to a clamping pad 6; a protective assembly is arranged on one side of the top of the placing plate 15, the protective assembly comprises a protective plate 7, the protective plate 7 is fixedly connected to one side of the top of the placing plate 15, one side of the fixing plate 1 is fixedly connected to a protective pad 8, and the other side of the fixing plate 1 is fixedly connected to a fixing pad 9.
[0025] Specifically: the shell 2 facilitates the fixing component to fix the thumb, the isolation plate 3 can prevent the fixing component from causing damage to the patient's skin during fixation, the clamping pad 6 can protect the patient's thumb to prevent the patient's skin from being worn due to long-term fixation, and the protective pad 8 and the fixing pad 9 can protect the patient's skin and metatarsophalangeal joints.
[0026] Embodiment 2
[0027] See also Figure 1-4On the basis of the first embodiment, tooth plates 10 are provided on both sides of the gear 5, and a connecting plate 11 is fixedly connected to one side of the bottom of the tooth plate 10, and the bottom of the connecting plate 11 is fixedly connected to the top of the fixed plate 1, and a limiting rod 12 is fixedly connected to the top of the inner cavity of the shell 2, and a slider 13 is slidably connected to the surface of the limiting rod 12, and the bottom of the slider 13 is fixedly connected to the top of the tooth plate 10, and a strap 14 is fixedly connected to the top of the protective plate 7 and the bottom of the placement plate 15. A Velcro is fixedly connected to one side of the bottom of the strap 14, and a handwheel is fixedly connected to one end of the rotating rod 4, and a limiting pin is provided on one side of the top of the handwheel, and one end of the limiting pin passes through the inside of the shell 2, and a sliding groove is opened inside the isolation plate 3, and the connecting plate 11 is slidably connected to the inside of the sliding groove. The material of the protective pad 8 and the clamping pad 6 is sponge, which is used to protect the patient's skin, and a fixing groove is opened inside the fixing pad 9 for protecting the metatarsophalangeal joint.
[0028] Specifically: there are two tooth plates 10, which are respectively engaged with both sides of the gear 5.
