Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0030] figure 1 It is a schematic flow chart of the method of the present invention. As shown in the figure, the manufacturing method of the orthosis disclosed by the present invention has the characteristics of macro-micro integration, including the following steps:

[0031] S1: Perform three-dimensional scanning of the patient's part to obtain the surface contour data of the patient's part;

[0032] A three-dimensional scanning device (for example, a hand-held three-dimensional scanner) is used to scan the patient's part to obtain surface contour data of the patient's part. During the scanning process, the surface contour data of the patient's part is displayed on the monitor in real time in the form of point cloud data or surface data (surface data automatically connected by point data), and the scanner can analyze the surface contour acco...

Abstract

The invention provides an orthosis manufacturing method with a macroscopic-microcosmic integration feature. A diseased part is scanned with three-dimensional equipment to acquire surface profile data of the diseased part, a three-dimensional model of the diseased part is rebuilt, then a digital entity model of orthosis is generated, the macroscopic morphology of the orthosis is designed and optimized, the target gap morphology is determined according to the conditions such as the variety, the breathability requirement and the weight of the orthosis, and then the orthosis with a plurality of gaps which are arranged transversally and longitudinally and mutually communicated is generated on the basis of the macroscopic morphology of the orthosis. The orthosis manufactured through the method has the optimized macroscopic morphology and microcosmic gap structure, is good in breathability and small in weight and has the individuality, the aesthetics and the reasonability, the orthosis entity is directly printed through a three-dimensional printing technique, the manufacturing efficiency is high, and manufacturing is more excellent; meanwhile, the orthosis is beneficial for early recovery of a patient by adding medicine for promoting recovery and orthosis and a lubricating agent for improving contact face friction in the microcosmic gaps.

Description

technical field [0001] The invention relates to a manufacturing method of an orthosis featuring macro-micro integration, and belongs to the technical field of rehabilitation orthopedic appliances. Background technique [0002] Orthotics are external devices assembled on the limbs and trunk of the human body to prevent or correct deformities of limbs and trunk or to treat bone joint and neuromuscular diseases and compensate their functions. Traditional orthotic manufacturing methods include manual molding, plaster mold making, shape modification, and resin pouring. Not only is the working environment harsh, the process is complicated, and the efficiency is low, but also affected by the level of orthotic technicians, the quality of the orthotics produced varies. If it is uneven, the corrective effect cannot be guaranteed. [0003] With the application of 3D technology in reverse engineering and the rapid development of 3D printing (rapid prototyping or additive manufacturing)...
