Product structure composition:

The lower limb orthosis is composed of joint parts, thigh bracket parts, leg bracket components and tension band

[scope of application]

It is suitable for knee varus and varus arthritis.

[contraindications]

Knee ankylosis, knee arthritis stage. Osteogeny varus and valgus.

[usage]

① The four tension bands of the combined lower limb orthosis were extracted from the clip connector to separate the thigh outer sheath from the thigh inner sheath: the lower leg outer sheath was separated from the lower leg inner sheath;

② The principle is that the adjustment system should be located on the outside of the affected leg and the center of its rotation axis should be consistent with the knee joint flexion center of the affected leg;

③ Put the corresponding tension band into the corresponding clip connector and tighten it so that the outer sheath of thigh and inner sheath of thigh are respectively placed on the outer side of thigh and the inner side of thigh; the outer sheath of lower leg and inner sheath of lower leg are respectively placed at the outer side and inner side of lower leg. It is required that the clip connector should be placed horizontally on the inside, and there should be no inclination to avoid affecting the tension. In order to ensure that the clip connector is flat, it can be realized by moving the black hole on the force increasing belt at the lower leg support plate and thigh support plate, that is, screw out the fixing screw, move the force increasing belt so that the clip connector on it is just at the flat position outside the inner leg sheath and the inner thigh sheath of the affected leg, and the fixed screw is penetrated into the corresponding screws of the lower leg support plate and the thigh support plate which are directly opposite to the loading band Screw the hole in the black eye.

④ The tension strap is threaded into the clip connector to tighten, and then the tension band is glued to complete the installation process, and the knee joint is properly flexed to feel the adaptation.

⑤ Some patients have a tendency of tension and need to limit over extension. At this time, the limit screw can be screwed into the corresponding hole to limit the angle of knee joint extension. The design of the invention has two limits, one is 10 degrees and the other is 30 degrees.

⑥ According to the doctor's plan, in the specified time interval and amplitude, rotate and adjust the handle to make the worm gradually change the angle, and then drive the leg to adduct or abduct around the knee joint. For patients with knee varus, it is necessary to adjust the abduction of the lower leg of the patient. In the process of gradual adjustment and change, the patient's lower leg and big leg will be changed gradually The angulation of the leg changes the knee joint space.

Due to the change of the stress state of the knee joint, the internal stress of the joint changes from non-uniform to uniform. The pressure pain point reduces the pressure and pain, and gradually changes the angle and persists for a certain period of time to repair the damaged part. According to the concept of human adaptation, the tissues around the knee joint change adaptively, and gradually restore the stability of the tissue around the knee joint, so that the knee joint osteoarthritis can be alleviated and corrected.

[precautions]

① The adjustment should be carried out gradually. ② the tension of the belt should be moderate and not easy to be too tight or too loose. ③ the carrying time depends on the recovery progress and should not be too hasty.
