Manufacturing process of full carbon fiber afo ankle-foot prosthesis

Abstract

The invention relates to a production process of a full-carbon-fiber AFO (Ankle Foot Orthosis) artificial limb, which comprises the following steps of: A: shape taking; B: positive mould casting; C: resin forming; D: polishing; E: mounting of a fiber carbon foot plate; F: secondary vacuum processing; G: polishing of a finished product. The full-carbon-fiber AFO artificial limb produced by the production process is simple in structure, convenient to wear, comfortable to walk and low in cost, can well assist in walking, and avoids bad lesions such as strephexopodia and strephexopodia, foot dropand the like in the future using process of an affected foot; by adopting full-contact design, an average pressure on a unit area is reduced, so that overloaded skin is partially free of load. Moreover, the larger the containing area is, the higher the load bearing capacity is. The residual limb is stressed uniformly so as to prevent swelling of the residual limb; sliding between the stump and anaccepting cavity is reduced, so that a case that the skin is stimulated and damaged is also reduced.

Description

technical field [0001] The invention relates to a manufacturing process of an artificial limb, in particular to a manufacturing process of an all-carbon fiber AFO ankle-foot prosthesis, and belongs to the technical field of medical devices. Background technique [0002] AFO ankle-foot prosthetics are also known as calf orthoses. It is an orthosis with a structure from the calf to the sole of the foot that controls the movement of the ankle joint. It can be divided into metal support bar ankle-foot orthosis, plastic ankle-foot orthosis, patellar ligament bearing ankle-foot orthosis, etc. AFO orthosis is one of the commonly used orthotics in clinical treatment. AFO orthosis controls abnormal movement patterns and spasticity of patients, corrects and prevents deformities, and performs compensation and orthopedic treatment for disabilities. It is an important means of rehabilitation treatment. The main function is to control the ankle joint or correct the deformity of the ankle...

Problems solved by technology

In the past, most patients with partial amputation wore traditional boot-shaped prosthetic half-foot prostheses. This prosthetic foot is made of materials such as leather socket, rubber foot end with leather pad and sponge, which can maintain the stability of the foot when walking. Make up for the appearance defects of the residual foot, but the prevention effect on the deformity of the foot is very poor, and it lacks the rolling characteristics of the forefoot when walking

At present, patients with foot amputations are generally equipped with silicone half-foot covers. This type of silicone half-foot covers has good decorative and aesthetic properties. It is used clinically to protect and stabilize the soft tissue of the residual limb, avoiding the friction of the residual limb in the receiving cavity and reducing the risk of injury. Stump pressure, but due to the inertia of the foot cover, and the lack of elasticity of the arch when walking, plantarflexion and dorsiflexion cannot compensate for the proper function of the foot, and the preventive effect on foot deformity is not obvious
