METHOD OF MAKING ORTHOPAEDIC PRODUCT Russian patent published in 2025 - IPC A61F5/01 G16H50/50 B29C64/393 B33Y50/02 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to a method of making an orthopaedic device. Method involves obtaining a digital three-dimensional model of the patient's body with subsequent programmed correction of the three-dimensional image taking into account the patient's pathology to form a digital model of the frame of the orthopaedic product and subsequent printing of the frame of the orthopaedic product on 3D printer. When forming a digital model of the frame of the orthopaedic device, data on mobility in human joints, data of anthropometric measurements and the purpose of the orthopaedic device are used. Orthopaedic product frame is printed on 3D printer from a thermoplastic material so that the surface of the orthopaedic product frame has through holes with a total area of not more than 80% of the area of the entire orthopaedic product, the linear dimensions of each through hole do not exceed 15 mm, thickness of the wall of the frame of the orthopaedic product was within range of 0.3 to 3 mm, and the density of filling the frame material of the orthopaedic product did not exceed 20%. Then the frame of the orthopaedic product is fitted on the patient and corrected by heating to the softening temperature of the thermoplastic material. Further, the surface of the frame of the orthopaedic product is laid on the convex side with a carbon fabric with total density of not less than 150 g/m², which is impregnated with a binding component; the carbon fabric is adapted to bends of the frame of the orthopaedic product. Then it is left till hardening at temperature lower than softening temperature of thermoplastic material from which frame of orthopaedic product is made. Then the orthopaedic product is subjected to mechanical treatment, in which excess carbon tissue and binder are removed, sanded, varnished for cosmetic purposes and fitted with fittings.

EFFECT: creation of a method for manufacturing an orthopaedic product with improved technical characteristics.
