Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a novel foot and ankle orthosis. Background Art

[0002] Foot drop is one of the signs of orthopedics. When the patient sits, the lower limbs hang naturally. If the foot is in plantar flexion and cannot actively dorsiflex, invert, or evert, it is foot drop. This sign can be seen in sciatic nerve palsy and common peroneal nerve palsy. In the former, the toes cannot dorsiflex or plantar flex, while in the latter, the toes can plantar flex. For patients with foot drop, they are usually corrected by using foot and ankle orthoses.

[0003] However, the existing ankle orthoses in clinical use are generally connected by gluing one side with fluff and the other side with a hook, or by snapping together with a snap fastener. Although this connection method is convenient, it is not firm, which can easily cause the ankle orthosis to fall off when the patient moves while wearing the ankle orthosis. If the patient chooses to connect the ankle orthosis with bolts and nuts, it will also be inconvenient for the patient to wear the ankle orthosis. Utility Model Content
