Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a preoperative brace for leg bone injuries. Background Art

[0002] In daily orthopedic care, patients with leg injuries or fractures often need to remain in bed while the swelling subsides. This process can be lengthy, and during this time, patients are unable to move their legs normally and must lie in bed with their legs elevated above heart level. This prolonged inactivity can lead to leg atrophy and blood clots.

[0003] To prevent the formation of blood clots, patients are often advised to perform continuous foot exercises such as toe curling. However, due to leg injuries, patients cannot achieve the normal toe curling angle and can only perform simple stepping movements. At the same time, because the patient's leg may twist unconsciously, this unconscious movement is not only difficult to control, but may also cause secondary damage to the injured area, further prolonging recovery time.

[0004] While there are currently some assistive devices on the market that can help patients with leg exercises, these devices are often complex, difficult to operate, and fail to effectively prevent secondary injuries. Therefore, a solution that can both help patients perform effective leg exercises and prevent secondary injuries is urgently needed to improve the effectiveness of orthopedic treatment and accelerate patient recovery. Utility Model Content

[0005] The purpose of the utility model is to provide a preoperative brace for leg bone injuries that is simple to operate and can improve rehabilitation and reduce swelling in response to the above problems.

[0006] In order to achieve the above-mentioned purpose, the utility model discloses a preoperative brace for leg bone injuries, including a bracket and a high-density sponge covering the bracket.
