Feature-based quick bone plate design method

Abstract

The invention relates to a feature-based quick bone plate design method. The method is characterized in that the method includes the following steps that 1, an interesting region is selected through border lines according to a bone model, and surface reconstruction is conducted on the interesting region; 2, feature definition and parameter setting are conducted on the reconstructed surface region, and a surface feature is generated; 3, a bone plate entity feature is built through the generated surface feature, a mapping relation between the surface feature parameters and the bone plate entity feature parameters is built, and later quick editing and altering are facilitated. The feature-based quick bone plate design method provides a certain theoretical basis for the bone plate design, particularly the individualized design of bone plates, the design cycle of the bone plates is shortened, and design efficiency is improved.

Description

technical field [0001] The invention relates to a digital orthopedic implant design technology, in particular to a feature-based rapid design method for a bone plate, which belongs to the field of computer-aided design. Background technique [0002] In recent years, with the rapid development of computer technology, electronic information technology, medical imaging technology and medical image processing technology, the new concept of digital orthopedics has gradually formed. As an important research content of digital orthopedics, digital orthopedic implant design has attracted extensive attention from domestic and foreign researchers. The most common orthopedic implants include: bone plate, intramedullary nail, steel pin, etc., among which the design of bone plate is the core of implant design. The existing bone plate design method includes the following basic steps: (1) Using the sample data obtained by CT / MRI scanning to reconstruct a mesh-based bone model, and splicin...

AI Technical Summary

Problems solved by technology

Therefore, even if the bone plate manufacturer divides its specifications and models sufficiently, the conformity between the bone plate and the bone surface and the position of the screw are still not ideal, and clinicians need to make multiple comparisons and shapes, resulting in long operation time and low efficiency
