Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of orthosis, in particular to a reset fixing orthosis for orthopedics. BACKGROUND

[0002] Biomedical engineering is a multidisciplinary field that combines mechanical engineering, materials science, electrical engineering, computer science, and biology. The progress of these disciplines directly translates into the upgrading of orthopedic devices. In order to prevent or correct deformities of the limbs and torso, or to treat bone and joint diseases and compensate for their functions, patients often need to wear orthoses.

[0003] According to the search, the Chinese invention patent with the publication number CN114587736B has the invention name of a reset fixing orthosis for orthopedics. The invention works through the walking of the wearer, which makes the damping mechanism and the rolling mechanism work. The damping mechanism works to buffer the vibration generated by the wearer walking while ventilating the air under the wearer's feet. The rolling mechanism works to massage the wearer's feet. It can effectively ventilate the wearer's feet, prevent the wearer from wearing for a long time, and prevent the wearer's feet from smelling and sweating. It improves comfort and prevents the wearer's feet from being injured and provides good protection for the wearer.

[0004] However, the above-mentioned and similar technical solutions still have some problems in actual use.

[0005] 1. The foot and leg positions are fixedly connected in an integrated manner. This design limits the natural activity of the feet. For patients with foot inversion or eversion, it is difficult to adjust the posture flexibly during walking, and it is difficult to adapt to individual walking training needs, reducing the applicability of the orthosis to different patients in rehabilitation training scenarios.

[0006] 2. In winter, the orthosis lacks a convenient and effective leg heating mechanism. Cold weather can cause blood vessels to constrict, hindering blood circulation and hindering patient recovery.

[0007] 3. When the patient's feet or legs sweat, the orthosis has some problems in terms of sweat treatment and cotton pad replacement. Due to the structural design, it is difficult to directly wipe and clean the feet. If you want to replace the cotton pad, you need to remove the bottom plate and the fixed plate, which not only increases the difficulty of the patient's operation, but also affects the rehabilitation effect.
