Convenient design method for customized implants based on bionic vein structure features

Area of Science:

• Orthopedic Medicine
• Biomedical Engineering
• Computer-Aided Design

Background:

• Customized orthopedic implants require precise bone matching.
• Current design methods using parameterized deformation lack integrated information management, hindering efficiency.
• Fragmented semantic parameter representation limits feature retrieval and design optimization.

Purpose of the Study:

• To propose a rapid design method for customized orthopedic implants.
• To leverage bionic vein structure features for improved implant design.
• To enhance the efficiency and flexibility of customized implant creation.

Main Methods:

• Designing a bionic vein structure to represent implant types.
• Representing the bionic vein structure using a digraph with morphological and dimensional features.
• Rapidly constructing implant models through sketch retrieval and modeling operations.

Main Results:

• The proposed method integrates bionic vein structure features with traditional parametric deformation.
• Demonstrated flexibility and efficiency in designing various common orthopedic implants (e.g., T-shaped plates, femoral stems).
• Experimental results confirm significant improvements in customized implant design efficiency.

Conclusions:

• The bionic vein structure feature-based method offers a flexible and efficient approach to customized implant design.
• This method overcomes limitations of traditional fragmented parameter representations.
• The study highlights a promising direction for advancing orthopedic implant customization.
