Abstract

The present invention provides an adjustable orthosis for degenerative joints, which comprises a corrective joint and two fastening-strap supports. The corrective joint comprises a fixing board assembly, two rotation rollers, a transmission axle, an operation piece, a transmission assembly, and a pushing member. The two rotation rollers are mounted on the fixing board assembly in a coaxially rotatable manner. The transmission axle is coupled to the two rotation rollers, and is arranged non-coaxially with respect to the two rotation rollers. The operation piece is fixed to the two rotation rollers. The transmission assembly has two opposite ends, and one of the ends of the transmission assembly is coupled to the transmission axle for being driven by the transmission axle to reciprocally move relative to the fixing board assembly. The pushing member is fixedly connected to the other end of the transmission assembly. The two fastening-strap supports are respectively coupled to two opposite ends of the fixing board assembly. To eliminate the drawback of the existing assistive correction device that has no concentrated correcting force, the present invention makes use of the corrective joint that is adjacent to the knee joint of a patient to directly apply a correcting force to the knee joint, so as to concentrate the force to enhance the effect of correction.

Degenerative knee joint adjustment bracket

This creative department relates to a corrective aid, especially a degenerative knee joint adjustment bracket that can provide direct corrective strength.

Human knee joints will degenerate due to age, overweight or overuse, causing knee pain and discomfort, inconvenience in walking, and knee joint deformation. In order to assist patients with knee joint degeneration to walk and live normally, assistive devices, such as correction straps, braces or knee pads, are used during the course of treatment to provide support to the knee joint of the patient.

An existing assistive device for treating knee joint degeneration includes: a strap bracket and a number of straps arranged on the strap support, which are tied to a single leg with a number of straps. Strength to improve the symptoms of knee joint degeneration in one leg; however, this kind of knee joint degeneration correction aid is prone to uneven straps, which will lead to inconcentration of support strength and reduce the effectiveness of the treatment.

To sum up, the existing knee joint degeneration correction aids cannot provide good improvement and support effects for patients. Therefore, there is still room for improvement and progress in the design of the aids.

In order to improve the existing knee joint degenerative correction aids, the support force is not concentrated due to uneven straps, this creation proposes a degenerative knee joint adjustment bracket, which corrects the joint system adjacent to the patient’s knee joint , And use the linkage assembly to drive the pusher to directly exert supportive force on the knee joint, so that the force can be concentrated and the support effect can be improved.
