Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, in particular to a hand tension deformity corrector. Background Art

[0002] A hand tension deformity corrector is a device specially designed to improve hand tension deformities. These deformities may be caused by congenital factors, trauma or pathological conditions, and manifest as excessive flexion or excessive extension of the hand joints, affecting the normal function and posture of the hand. The main function of this corrector is to adjust the muscles and joints of the hand by applying appropriate pressure and providing support, thereby promoting the balanced development of the hand muscles and improving the hand's posture control and power output. The hand tension deformity corrector is not just a simple support device, but also a therapeutic tool supported by scientific mechanical principles and medical theories. It is a key auxiliary means to restore and optimize the patient's hand function.

[0003] Most existing hand tension deformity correctors can only perform stretching exercises on the palms during correction, resulting in insufficient restoration of finger independence and flexibility, affecting the overall recovery of the hand. Patients may also find it difficult to complete tasks that require fine finger control, such as picking up small objects or tying shoelaces.

[0004] To this end, we provide a hand tension deformity corrector to solve the above problems. Utility Model Content
