A design and modeling method for corrective brace maintaining fitting all the time, and system

Abstract

The invention discloses a design and modeling method for a corrective brace maintaining fitting all the time, and a system. A corrective brace includes a rigid outer layer model and a flexible inner layer model. The modeling method for the inner layer model includes obtaining three-dimensional surface models of a to-be-fixed part under swelling and normal states; unfolding the three-dimensional surface model of the swelling state, and mapping the model to a plane through conformal mapping; performing equilateral triangular mesh generation on the model in the plane, performing reflecting to thethree-dimensional surface model of the swelling state, taking the connection line of the central point of the adjacent two sides of each equilateral triangle as an edge, and re-performing mesh generation so that an initial stretching structure can be obtained; and performing optimization on the initial stretching structure so that the stretching structures corresponding to the swelling and normalstates can be obtained. The costumed corrective brace can always maintain fitting and good heat dissipation, and is high in comfort level.

Description

technical field [0001] The invention relates to the technical field of brace design oriented to 3D printing, in particular to a design, modeling method and system for always maintaining a fit correction brace. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] 3D printing technology is based on digital model files, using metal powder, nylon, plastic and other bondable materials to construct physical objects by layer-by-layer printing. From the perspective of process comparison, 3D printing technology can achieve high-precision printing through pre-modeling, with high efficiency and material saving, which is unmatched by traditional processes. [0004] my country introduced 3D printing technology into the medical industry in the late 1980s, and the development of 3D printing technology and the combination with medical care are getting deeper...

AI Technical Summary

Problems solved by technology

During the recovery process of fracture patients, the injured part may change with the reduction of swelling. However, because the traditional brace is made of rigid materials and is not easy to deform, it cannot fit the injured part during the rehabilitation process, which may seriously cause secondary injuries.
