Diversified design method of tibial T-shaped bone plate based on parametric technology

Abstract

The invention discloses a parameterization technology based diversified design method for a T-shaped tibial connection plate. The method comprises the following steps: step 1, constructing the T-shaped tibial connection plate: drawing a boundary of the T-shaped tibial connection plate by utilizing a boundary line, and performing curved surface reconstruction on a region by constructing an internal constraint line; step 2, setting shape structure characteristics and parameters of the T-shaped tibial connection plate: defining characteristic points and characteristic lines on the reconstructed curved surface region to realize the setting of the characteristics and the related parameters; and step 3, performing diversified design on the T-shaped tibial connection plate: constructing a T-shaped tibial connection plate entity by utilizing a curved surface reconstructed in the step 1, and establishing a mapping relationship between a surface parameter and an entity thickness parameter, so that later fast editing and modification are facilitated for realizing diversified design. According to the method, the digitization, diversification and precision of tibial connection plate design can be realized through parameterization definition of the tibial connection plate; and the method has an important significance for improving the quality and efficiency of the tibial connection plate design.

Description

technical field [0001] The invention relates to a design technology of digital orthopedic implants, in particular to a method for diversified design of a tibial T-shaped bone plate based on parametric technology, and the invention belongs to the field of computer-aided design. Background technique [0002] With the advent of the computer digital age, the problem of digital orthopedics has become more and more prominent. Artificial orthopedic implants have been developed for more than a century and have become necessary to treat severely damaged bones. 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. However, the current method of designing implants is based on the three-dimensional mesh model of the bone, directly through the existing commercial CAD software and a large number of human-computer interaction to design and realize. This method needs to consume a l...

AI Technical Summary

Problems solved by technology

This method needs to consume a large amount of manpower and material resources, but the result is unsatisfactory and inaccurate

Also for doctors, it is necessary to artificially rely on clinical experience to continuously bend and change the bone plate in an appropriate amount during the operation process. It can be said that the bone plate designed in this way has brought great inconvenience to doctors and patients.
