Embodiment 1

[0021] With reference to accompanying drawings 1 and 2 of the description, the knee joint varus and valgus deformity corrector of the present invention includes a thigh collar 1 and a calf collar 5, and is arranged on the inside of the leg, and is connected to the thigh collar through connecting plates 2 and 4 respectively. 1 and the universal joint 3 that is tightly connected with the calf hoop 5, and the foot hoop 7 that is connected with the calf hoop through the connecting plate 6. The above-mentioned connecting plate is made of stainless steel plate, and its strength is mainly considered. Using a high-strength steel plate can achieve a smaller size and meet the required strength requirements, and also make the structure of the aligner more compact.

[0022] Among them, the universal joint includes a steel cylinder 8 welded to the connecting plate 2 and has an internal thread, a steel cylinder 11 threaded with the steel cylinder, a connecting rod 12 threaded with the steel ...

Embodiment 2

[0028] With reference to accompanying drawings 1 and 2 of the description, this implementation ideally should be in accordance with embodiment 1, the main difference is that it is applied to the situation where there is a damaged surface in the outer joint of the knee varus or valgus deformity, that is, the universal joint 3 is set on the outer side of the right leg . Considering the manufacturing cost simultaneously, adopt thigh hoop 1, shank hoop 2 front sides to be provided with a long strip hole, its inner side is provided with evenly distributed sponge or cotton lining. There is a 4cm margin for the thigh cuff and the calf cuff corresponding to the physiological structure of the human body. In fact, the larger the margin, the easier it is to wear, but it will have an adverse effect on the binding, that is, to balance the resilience of the base of the leg sleeve, a greater binding force is required. The maximum size is 5cm. If it is too large, the binding force required w...

Embodiment 3

[0030] Refer to Figures 1 and 2 of the instruction manual. In fact, in order to obtain a more ideal correction effect, no matter whether the articular surface is damaged on the side of the knee varus or valgus deformity, if a universal joint 3 is installed on the inner and outer sides of the leg, it will be more effective. Good results. One is that the whole orthotic has high structural strength and good stability due to the adoption of two universal joints, and the adjustment is more convenient. For situations where the entire articular surface is damaged, this is an inevitable choice in the present invention.

Abstract

The invention relates to an eversion and enstrophe malformation corrector of knee joint, which comprises a thigh socket and a curs socket, further comprising a gimbal arranged at the inside, outside or two sides of the leg and fixedly and respectively connected with the thigh socket and the curs socket through a connecting board, and a leg socket connected with the curs socket through the connecting board. Wherein the gimbal can rotate around the centre axis and bend at the joint of the two connecting rods. The leg socket is articulated with the curs socket through the connecting board. Under the circumference that sufferers can walk as normal man, the invention can ensure the abrasion surface of the knee joint recover naturally, with convenient use and low cost.

Description

(1) Technical field [0001] The invention relates to a knee joint varus and valgus deformity corrector, in particular to an adjustable knee varus and valgus deformity corrector, which belongs to the technical field of medical devices. (2) Background technology [0002] With the aging of my country's population, the incidence of knee osteoarthritis is also on the rise. The disease is one of the main causes of knee pain in the elderly. People over the age of 50 often have knee osteoarthritis.
