Description
Technical Field
The utility model belongs to the technical field of the medical treatment orthopedic ware, concretely relates to lightweight hollow out construction ankle foot orthopedic ware based on 3D printing technique.
Background
Ankle foot orthotics, which are generally used to provide protection to a patient's ankle and foot while providing support against excessive plantarflexion (colloquially referred to as "foot drop"), may be used to support, protect, correct or protect a patient's limb by exerting a force on the patient's limb to effect the correction. Plantarflexion is a medical condition caused by disease, trauma, or congenital abnormalities. Patients affected by this disease typically have difficulty walking because the patient's feet generally tend to droop when lifted off the ground, so to avoid tripping over, the patient typically must lift the foot higher than it should. The primary function of the ankle foot orthosis is to provide resistance to plantarflexion, helping to maintain the patient's foot in the correct position when the foot is raised above the ground. When the existing ankle and foot corrector is used, symptoms such as varus and lower limb outward rotation deformity can be caused, and the optimal treatment limb position of a patient cannot be maintained, so that the recovery time and the treatment effect of the patient are influenced.
