Technical Field
The utility model relates to the technical field of orthopedic auxiliary appliances, in particular to a knee joint orthosis.
Background
The knee joint orthosis is a common knee joint rehabilitation auxiliary device, and consists of a liner, a belt pad, a knee protection pad, a buckling belt, a lock pin, an angle adjusting disc, a stainless steel pipe frame, an aluminum frame or an aluminum oxide plate, a plastic straightening limiting block, a buckling limiting block, a lantern ring and the like, and has the function of limiting the extension and the buckling of the knee joint within a proper moving range or fixing the knee joint at a certain angle so as to promote the recovery of the function of the knee joint.
At present, common knee joint orthotics in the market mainly play roles in supporting and stabilizing the damaged knee joints of patients. However, these knee joint orthoses cannot adapt to the change of the muscle shape of the thigh and the lower leg during walking, and when the change degree of the muscle shape is large, the knee joint orthoses can slip and cannot be well fixed on the lower limb of the patient. The displacement of the knee brace can cause the patient to become burdened with walking and can even cause the patient to fall, which in the long run can cause pain to the patient by wearing the knee. The reason is that the existing knee joint orthotics cannot change along with the deformation of muscles in the knee extension and knee flexion processes of patients, once a large gap is formed between a pad and the skin, friction cannot be generated, and the knee joint orthotics cannot rapidly fall down to cause slippage without friction against gravity.
Disclosure of Invention

The utility model provides a knee joint orthosis capable of changing shape along with the deformation of lower limb muscles, which comprises an elastic fixing trousers and a protective exoskeleton, the elastic fixing trousers comprise high-elasticity trousers and four connecting blocks, the two connecting blocks are respectively fixed on the front sides of thighs and the front sides of shanks of the high-elasticity trousers, the exoskeleton for protection comprises a thigh protective shell, a shank protective shell and two adjustable knee joint hinges, the thigh protective shell and the shank protective shell are respectively connected into a whole through two adjustable knee joints, two groups of connecting block fixing switches are respectively arranged at the front sides of the thigh protective shell and the shank protective shell, each group of connecting block fixing switches comprises a pair of fixing bars, a rectangular buckle and a trapezoidal switch, the thigh protective housing and the shank protective housing are provided with a pair of fixed wrapping cloth at the rear side respectively, and each pair of fixed wrapping cloth is provided with two pairs of magic tapes.
When the adjustable knee joint hinge is used, the elastic fixing trousers are firstly worn on the lower limbs, the protection exoskeleton is fixed on the elastic fixing trousers through the embedding of the connecting block fixing switch and the connecting block, then the thigh and the shank are wrapped by the fixing wrapping cloth on the protection exoskeleton and fixed through the magic tape, and finally the angle of the chuck of the adjustable knee joint hinge is adjusted to a proper position, so that the adjustable knee joint hinge can be used.
Compared with the prior art, the utility model has the following advantages:
1. the utility model provides an orthosis fixing mode, wherein a knee joint orthosis is fixed on a lower limb through elastic fixing trousers capable of changing shapes along with the deformation of lower limb muscles, so that the knee joint orthosis which cannot be adapted to the lower limb muscles in motion and the lower limb muscles can move together, the probability of slipping of the knee joint orthosis is reduced, direct friction between the knee joint orthosis and thigh muscles is reduced, and the comfort of a patient wearing the knee joint orthosis is improved.
2. When the elastic fixing trousers are worn, a certain pressure can be applied to the lower limbs of a human body, so that the backflow of venous blood of the lower limbs is promoted, the blood circulation of the lower limbs is accelerated, the recovery speed of a patient is improved, and meanwhile, the generation of complications such as lower limb varicose veins and lower limb muscular atrophy can be prevented.
In conclusion, the knee joint orthosis has the advantages of ingenious structure and convenient installation, reduces the slipping probability of the knee joint orthosis, simultaneously gives certain pressure to the lower limbs, improves the rehabilitation speed and the rehabilitation quality of patients, has higher economic value and application value in the aspect of auxiliary medical treatment, and is suitable for large-scale popularization.

Detailed Description
The utility model will now be described in detail with reference to the accompanying drawings.
Referring to fig. 1 to 2, the knee joint orthosis capable of changing shape along with the deformation of lower limb muscles provided by the utility model comprises two large modules, namely elastic fixing trousers and an exoskeleton for protection. The two modules are connected and combined through a connecting block fixing switch 1. The connecting block fixing switch 1 comprises a connecting block 1a, a rectangular buckle 1b and a trapezoidal switch 1c, wherein the connecting block 1a is sewn on the high-elasticity trousers 6 to form an elastic fixing trousers module, and the rectangular buckle 1b and the trapezoidal switch 1c are fixed on a shank protective shell 2 and a thigh protective shell 4 of the exoskeleton module for protection. Shank protective housing 2 and thigh protective housing 4 are connected through a pair of adjustable knee joint hinge 3, and two adjustable knee joint hinges 3 set up and pass through the screw fixation in shank protective housing 2 and thigh protective housing 4 left and right sides, and the accessible adjusts the flexible angle change shank protective housing 2 and the thigh protective housing 4 between the scope of stretching. The rear sides of the shank protection shell 2 and the thigh protection shell 4 are respectively provided with a pair of fixed wrapping cloth 5. The fixed wrapping cloth 5 is fixed between the adjustable knee joint hinge 3 and the interlayer of the shank protective shell 2 or the thigh protective shell 4 by screws. Each pair of fixed wrapping cloth 5 is composed of two pieces of knitted fabric, and the surface of each pair of fixed wrapping cloth is provided with a magic tape which is connected through the magic tape.
