Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0032] Such as figure 1 , this three-dimensional scanning-based bone orthopedic brace shaping method of the present invention comprises the following steps:

[0033] S01: Use 3D scanning equipment to obtain 3D point cloud data of human body parts;

[0034] S02: Preprocessing the obtained 3D point cloud data, removing abnormal points in the point cloud, and performing smoothing and denoising processing;

[0035] S03: Using the processed 3D point cloud data, calculate the vertex normal vector of the 3D point cloud data. The main steps are:

[0036] 1) For any point p, use the points in the neighborhood to calculate the scanning point cloud density ρ=N / (πd 2 ), where N is the number of selected neighborhood points, d represents the average distance from point p to N domain po...

Abstract

The invention provides a skeleton orthosis brace shaping method based on 3D scanning. The method includes the steps that a 3D scanning technology is used for accurately acquiring point cloud data on the surface of a body part, and 3D modeling is carried out; an X-ray radioscopy device is used for acquiring skeleton information, and a 3D model is corrected; then, a 3D printing technology is used for conducting portioning multi-line printing, an orthosis brace is made, and finally forming is achieved by splicing. Compared with a gypsum shaping mode, the skeleton orthosis brace shaping method has the advantages of being low in cost, convenient to implement, high in speed, high in modeling precision, environmentally friendly and the like.

Description

technical field [0001] The invention relates to a manufacturing method of a medical orthopedic device, in particular to a method for shaping a bone orthopedic brace based on three-dimensional scanning. Background technique [0002] Scoliosis correction and prevention mainly include sports correction, brace correction and surgical treatment. Generally, the appropriate method is selected according to the degree of side bending. Among them, brace orthopedics has the advantages of easy implementation, good effect, and stable curative effect, and is widely used in orthopedics such as scoliosis. The shape of the traditional brace is shaped by plaster. The shaping effect is limited by the professional level of the brace technician. At the same time, it brings a lot of inconvenience to the patient and the cost is high. The three-dimensional model of the brace is obtained by three-dimensional scanning, and then printed by a 3D printer, which can be made into a brace that completely...
