Intelligent construction method and system for orthopaedic implant class characteristics

Abstract

The invention discloses an intelligent construction method and system for orthopaedic implant class characteristics. The method comprises the following steps: S1, carrying out restoration processing on a fuzzy region in a fracture image, and extracting fracture characteristics by training a deep convolutional neural network model; s2, extracting the collected bone morphological parameters througha principal component analysis method and a decision tree to obtain bone morphological characteristics; and S3, fusing the fracture characteristics and the bone morphological characteristics into implant characteristics to generate implant class characteristics. The system corresponds to the method. According to the method and system, an internal correlation mechanism of implant characteristics and skeleton characteristics is established, so that repeated definition of the characteristics is avoided; moreover, the method and system are high in flexibility and strong in applicability, shorten the design period of the implant, have important theoretical significance and practical application value for improving the efficiency and automation level of fracture preoperative planning, and have very wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of computer-aided analysis, and in particular relates to a method and system for intelligently constructing features of orthopedic implants. Background technique [0002] The construction of orthopedic implant features is an important link in the preoperative planning of fractures and plays a crucial role in the effect of surgical treatment. Orthopedic implants refer to devices and materials that are surgically implanted into the human body to replace and repair the patient's bones, joints, cartilage and other tissues, or to position and support these tissues. In recent years, with the continuous improvement of medical level and health awareness, as well as the increasing degree of population aging, the scale of my country's implant market has continued to grow rapidly. At present, the design of implants mainly adopts digital technology, and is gradually developing in the direction of intelligence. However...

Problems solved by technology

However, the application of digital technology in medical methods is a very unique interdisciplinary field at home and abroad. At this stage, in the process of constructing implant models, it still relies on too much medical-industrial interaction, and the degree of automation is not high.

This is due to the lack of effective design patterns and parameter carriers, resulting in design errors and prolonging the design cycle
